[0009] 例如,诸如这样的系统已经被用于提供对制冷剂泄漏进行检测的监控功能和其它有毒气体监控应用。 [0009] For example, as such a system has been used to provide a refrigerant leak detection monitoring, and other toxic gas monitoring applications. 与此相似的其他系统,例如Veelenturf等人的美国专利第6,241, 950 号描述的系统(通过引用将该专利并入本文中),公开了一种流体采样系统,包括集气管, 所述集气管具有输入、一般净化和采样路径、以及阀,所述阀耦合/去耦合第一组输入和第二组输入,用于测量穿过采样位置的压力差分。 Similarly to other systems, e.g., U.S. Patent No. 6,241, 950, the system described Veelenturf et al (hereby incorporated by reference herein), discloses a fluid sampling system comprising a manifold, the manifold having an input, the general purification and sample path, and a valve, the valve coupling / decoupling a first set of inputs and a second set of inputs, for measuring the pressure differential across the sampling positions.

[0010] 此外,这些类型的星形配置的系统已经用于以单个微粒计数器监控多个区域(例如干净房间区域)中的微粒。 [0010] In addition, in a star configuration of these types of systems have been used in a single particle counter to monitor a plurality of regions (e.g., clean room area) microparticles. 该设备的现有技术示例是复用微粒计数器,诸如Lighthouse Worldwide Solutions有限公司制造的通用集气管系统和控制器,与他们的微粒计数器(例如他们的型号Solair 3100的基于便携式激光器的微粒计数器或基于遮蔽的微粒传感器)華禹合。 An example of this prior art device is multiplexed particle counter, such as a universal manifold system and the controller Lighthouse Worldwide Solutions Limited manufactured, and their particle counter (such as their model Solair 3100 portable laser based particle counter or based sheltered particulate sensor) Huayu together.

Sharp的美国专利第6,125,710号中描述了示例性网络化空气采样系统,通过引用将该专利并入到本文中。 Sharp U.S. Patent No. 6,125,710 describes an exemplary networked air sampling system, which patent is incorporated by reference herein. Siarp等人的题为“Air Quality Monitoring Systems and Methods”的美国专利申请第09/779,379号提到了不同的多点空气监控系统,包括用于专家系统分析性能的多点空气采样系统,也通过引用而将该专利申请并入本文中。 Siarp et al., Entitled "Air Quality Monitoring Systems and Methods" US Patent Application No. 09 / 779,379 referred to the different multi-point air monitoring systems, including multi-point air sampling system is used to analyze the performance of the expert system, but also by reference in this patent application is incorporated herein. [0013] 最后,可以用于实现本发明的各部分的另一复用形式的设施监控系统在本发明的上下文中被定义为网络化的光子采样系统,其复用光的分组而不是空气的分组,并且可以包括星形配置的布局或网络/总线类型的布局。 [0013] Finally, another may be used to implement various parts of the complex of the present invention is defined in the form of facility monitoring system in the context of the present invention for networked photonic sampling system-multiplexed optical packet instead of the air packet, and may include a star configuration or layout of the network / bus type of layout. 基本构思使用中央激光发射器和中央激光检测器,所述中央激光检测器发送出激光分组,并对其进行检测,所述激光分组被切换进入房间,以由光学开关来感测。 The basic idea of using a central laser transmitter and central laser detector, said central laser detector laser sends out a packet, and detects it, the packet is switched laser light to enter the room, to be sensed by the optical switch. 在所感测的区域中定位和使用光纤传感器、红外线吸收单元或传感器、以及其它感测技术,以由于环境的影响而改变光的特性。 Positioned in the sensed area and use of fiber optic sensors, infrared absorption unit or sensors, and other sensing technologies, due to environmental influences which change the optical characteristics. 其后,光分组被切换回到中央检测器,在所述中央检测器中,确定环境对光特性的影响。 Thereafter, the optical packet is switched back to the central detector in the central detector, to determine the effect of ambient light characteristics. 这种系统的主要优点在于,诸如光纤传感器或开放式单元传感器之类的传感器潜在地成本很低。 The main advantage of this system is that the optical fiber sensor such as a very low open cell or a sensor like sensor potentially cost. 昂贵的部分是激光器和中央式的检测器系统。 Expensive part is a laser-type detector and the central system. 与前面的多点空气采样系统相似,可以利用中央设备和电信概念的波分复用来同时进行对来自微粒、气体、和其它污染物、湿度等对光的多种影响,其中波分复用允许多个波长,并且因此多路信号共享同一光纤。 Similar to the previous multi-point air sampling system, can utilize the concept of a central telecommunications equipment and wavelength division multiplexing is performed simultaneously on a variety of influences from particles, gases and other pollutants, humidity and other light, wherein the wavelength division multiplexing allows multiple wavelengths, and thus multiplexed signals share the same fiber. 该系统的明显优点是具有周期时间非常快速的能力,该时间周期可以是几十毫秒或更短。 Obvious advantage of this system is the ability to have a very fast cycle time, the time period may be several tens of milliseconds or less. 题为“Networked Photonic Distribution System forSensing Ambient Conditions”的美国专利第6,252,689号详细描述了这种采样系统,通过引用并入本文中。 Entitled "Networked Photonic Distribution System forSensing Ambient Conditions" U.S. Patent No. 6,252,689 describes in detail such a sampling system, incorporated by reference herein.

[0014] 前述的多点空气采样系统和网络化光子采样系统合起来被称为采样系统,其可以应用于监控整个建筑物的广大范围的位置,包括任意类型的房间、过道、大厅、间隙空间、楼顶房间、室外位置、以及管道系统、通风间和空气处理器内的任意数量的位置。 [0014] The foregoing multi-point air sampling systems and networked photonic sampling system together is called the sampling system, which can be used to monitor the position of the majority of the range of the entire building, including any type of room, hallway, hall, the interstitial space , the roof of the room, an outdoor location, and piping systems, ventilation and air in between any number of processors position. 为了提供这些不同空间的控制和监控,可以创建虚拟传感器信号或连续的模拟信号或数字信号,所述虚拟传感器信号在本发明的上下文中指的是软件变量或固件变量,所述连续的模拟信号或数字信号可以被传递到其它系统(例如建筑物控制系统或实验室空气流控制系统),并且表示给定空间的空气质量参数值的状态。 In order to provide these different spatial control and monitoring, can create a virtual sensor signal or a continuous analog signal or a digital signal, the virtual sensor signal is the present invention in the context of the middle finger is the software or firmware variable variable, the continuous analog signal or digital signal may be passed to other systems (e.g., building control systems or laboratory airflow control system), and shows the state air quality parameter value to the given space. 实际上,这些信号反映了如果使用本地传感器而不是多点空气采样系统或网络化光子采样系统(共同被称为采样系统),则本地传感器将有怎样的读数。 In fact, if you use these signals reflect local sensor instead of multi-point air sampling system or networked photonic sampling system (collectively referred to as sampling system), there will be what the local sensor readings.

[0015] 多点空气采样系统已经与很大范围的空气质量参数传感器一起使用,以监控建筑物或设施的很大范围的空气质量属性或空气特性。 [0015] multi-point air sampling system has been used with a wide range of air quality parameter sensors to monitor a wide range of buildings or facilities, air quality or air characteristic properties. 在本发明的上下文中,空气质量参数传感器是可以检测一个或多个空气质量属性或参数的传感器,其将空气质量参数的存在情况的水平或者关于空气质量参数的存在情况的信息转换为连续改变或不连续的气动、电子、 模拟或数字信号,或转换为软件或固件变量,所述软件或固件变量表示在给定空间中的空气质量参数的存在情况的水平或者关于空气质量参数的存在情况的信息。 In the context of the present invention, the air quality parameter sensor can detect one or more air quality attributes or parameters of a sensor, which converts the information level of air quality parameters with regard to the presence or the presence of air quality parameter is continuously varied or discontinuous pneumatic, electronic, analog or digital signal, or converted to software or firmware variables, the variables represented in the software or firmware to the horizontal space air quality parameters or the presence of information on the presence of the air quality parameter information. 空气质量参数传感器可以基于本领域技术人员所知的各种感测技术中的任何技术,例如电化学、光子或光学、红外吸收、光声、聚合物、可变电导率、火焰离子化、光离子化、固体状态、混合金属氧化物、离子迁移、声表面波、或光纤。 Air quality parameter sensor may be known to a person skilled in the art based on a variety of sensing techniques in any technique, such as electrochemical, photon or optical, infrared absorption, photoacoustic, polymer, variable conductivity, flame ionization, light ionization, solid state, mixed metal oxide, ion mobility, surface acoustic wave, or optical fiber. 空气质量参数传感器可以是有线传感器类型或无线传感器类型,并可以用各种类型的物理硬件(例如基于微电机械系统(MEMS)的硬件、基于纳米技术的硬件、基于微系统的硬件、基于模拟的硬件、或基于数字的硬件)来实现。 Air quality parameter sensor may be a wired or wireless sensor type sensor type, and may be used for various types of physical hardware (e.g., based on micro electro-mechanical systems (MEMS) hardware, nanotechnology-based hardware, hardware-based micro-system, based on analog hardware, or based on digital hardware). 此外,空气质量参数传感器可以感测多于一个的空气质量参数,并且可以在单个封装的设备中包括多于一个的空气质量参数传感器。 In addition, the air quality parameter sensor may sense more than one air quality parameter, and may include more than one air quality parameter sensor devices in a single package.

[0016] 此外,为了本专利的目的,空气质量参数被定义为一种空气特性,其可以包括空气污染物、空气舒适度参数、或二氧化碳(C02)。 [0016] Further, the present patent for the purpose of the air quality parameter is defined as a characteristic of the air, which may include air pollutants, air comfort parameters, and carbon dioxide (C02). 在本发明的上下文中,空气污染物指的是空气的某种潜在有害或刺激性化学、生物、或放射性复合元素或特性,例如C0、各种尺寸的微粒、烟、悬浮物、TVOC(挥发性有机化合物总量)、感兴趣的特定V0C、甲醛、N0、N0X、S0X、S02、 硫化氢、氯、氮氧化合物、甲烷、烃、氨、制冷气体、氡、臭氧、放射物、生物和/或化学恐怖活动制剂、其他有毒气体、霉菌、其他生物物质、以及要被感测的其它污染物。 In the context of the present invention, refers to a certain air pollutants potentially harmful or irritating chemical, biological, or radiological properties of the composite element or air, for example C0, various sizes of particles, smoke, suspended solids, TVOC (volatile the total amount of organic compounds), a specific V0C of interest, formaldehyde, N0, N0X, S0X, S02, hydrogen sulfide, chlorine, nitrogen oxides, methane, hydrocarbons, ammonia, refrigerant gases, radon, ozone, radiation, biological and / or chemical terrorist agents, other toxic gases, fungi, other biological materials, and other contaminants to be sensed. 此外,空气污染物具体地说不表示这样的其它空气质量参数,例如温度、二氧化碳、或者对空气中的水分或湿度的多种形式的测量中的任意一个,例如以下参数中的任意一个:比如相对湿度、露点温度、绝对湿度、湿球温度、焓等。 In addition, air pollutants not specifically represent such other air quality parameters, such as temperature, carbon dioxide, or any of the various forms of measurement of moisture in the air or in a humidity, for example, any one of the following parameters: for example, relative humidity, dewpoint temperature, absolute humidity, wet bulb temperature, enthalpy and the like.

[0017] 此外,空气污染物可以进一步被再划分为两种类型,基于气体的污染物和基于微粒的污染物。 [0017] In addition, air pollutants may be further subdivided into two types, based on pollutant gases and particulate pollutants. 基于气体的污染物在本发明的上下文中被定义为作为基于气体或蒸气的空气污染物(例如CO、TV0C、臭氧等)。 Based contaminant gases in the context of this invention, is defined as the gas or vapor based air pollutants (e.g. CO, TV0C, ozone, etc.). 另一方面,基于微粒的污染物包括任意尺寸的生存和非生存的空气传播微粒物质,但通常微粒大小是直径0.01微米到100微米。 On the other hand, based on the particles include any size of contaminant existence and non-existence of airborne particulate matter, but usually particle size is 0.01 microns to 100 microns in diameter. 这样,这种类型的污染物还包括所有生物微粒物质,例如霉菌孢子、细菌、病毒等。 Thus, this type of contaminants including all biological particulate matter such as mold spores, bacteria, viruses and the like.

[0018] 二氧化碳具体指的是作为除了氧和氮之外的组成成分在大气中可自然找到的气体二氧化碳。 [0018] Specifically referring to carbon dioxide as a gaseous carbon dioxide in addition to oxygen and nitrogen components in the atmosphere can be found in nature. 它在外部空气中的浓度典型地在300PPM和500PPM之间,并且对于正在进行典型办公室工作的人来说以每人0. OlCFM的近似速率由人类呼出。 Its concentration in the outside air and is typically between 300PPM 500PPM, and being typical for people who work in the office a rate of approximately 0. OlCFM per person exhaled by humans. 与送入建筑物的外部空气量相比,办公室里的人的数量的变化可以容易地将室内的C02水平改变到500PPM到2500PPM之间。 Compared with the amount of outside air into the building, the number of changes in the office of the person can easily change the levels of C02 to chamber between 500PPM to 2500PPM. 这样,由于空间中的C02的水平直接与C02从室外水平的增大除以空间中的人数有关,因此C02可以被用作基于每人的合适通风(有时也称为CFM外部空气每人)的极好的指标。 Thus, since the horizontal space C02 and C02 directly from the increased number of outdoor space divided by the level, and therefore C02 can be used as a suitable ventilation per person based (sometimes referred to as the outside air per CFM) of excellent indicators. 虽然高C02水平通常与差的室内空气质量水平关联,但并非是C02自身的水平创建了与差的室内空气质量关联的不舒适和症状,而是关联的空气污染物的增多没有被合适地稀释。 Although the high C02 levels are usually associated with poor indoor air quality and level, but not the level of C02 itself creates poor indoor air quality associated with discomfort and symptoms, but is associated with the increase in air pollutants are not suitably diluted . 人类不受相对高水平的C02 (例如高到5000PPM)的影响,5000PPM在任意普通结构的建筑物中都是及其难被发现的。 Effect of humans from relatively high levels of C02 (e.g. high to 5000PPM) of, 5000PPM in the building in any conventional construction and is difficult to be found.

[0019] 为了本专利的目的,空气舒适度参数具体地是指温度的测量或空气中的水分或湿度的许多相关的干湿测量中的一种,例如相对湿度、露点温度、绝对湿度、湿球温度、和焓。 [0019] For purposes of this patent, air comfort parameter specifically means measuring the temperature of the wet and dry many related measurements or moisture in the air or moisture in one, such as relative humidity, dewpoint temperature, absolute humidity, wet bulb temperature, and enthalpy. 空气舒适度参数也不是指二氧化碳或任意空气污染物。 Air comfort parameters nor refers to any carbon dioxide or air pollutants. 此外,在本发明上下文中,空气质量参数、空气污染物、或空气舒适度参数具体不包括以下参数的任何测量:空气流量、速度、或压力,例如以下测量:可以用每分钟立方英尺空气为单位或其它单位来表示的空气量、速度压力、空气速率或速度、静压、差分压力、或绝对压力。 Further, in the context of this invention, the air quality parameters, air pollutants, or air comfort parameter specifically does not include any measure the following parameters: air flow rate, speed, or pressure, for example, the following measurement: can be used as a cubic foot of air per minute amount of air units or other units represented by the velocity pressure, air velocity, or speed, static pressure, differential pressure, or absolute pressure.

[0020] 过去,现有技术多点空气采样系统已经频繁被使用来对于一个或多个被分别感测的空气质量参数提供监控、数据日志记录、告警、控制、或限制功能,但并未针对混合或复合的空气质量参数信号。 [0020] In the past, the prior art multi-point air sampling system has frequently been used to for one or more air quality parameters are being measured to provide monitoring, data logging, alarm, control, or limit the function, but not for blended or composite air quality parameter signal.

[0021] 在本发明上下文中,混合空气质量参数信号(也称为复合空气质量参数信号)被定义为模拟信号、数字信号、光学信号、软件或固件变量或地址位置或信息的其它基于时间的表示,其受到多个空气质量参数的影响、或与其有关、或以某种方式成为其函数,所述多个空气质量参数与一个或多个位置有关,例如房间、空间、区域、空气管道、或建筑物内的风险环境或建筑物或设施周围或附近的周围条件。 [0021] In the context of this invention, the mixed air quality parameter signal (also called composite air quality parameter signal) is defined as an analog signal, the other time-based digital signals, optical signals, or a software or firmware variable location or address information said plurality of air which is affected quality parameters, or relating to, or in some way become a function thereof, the plurality of air quality parameters related to one or more locations, such as a room, space, region of the air duct, or risk surrounding environment or building or facility or around the vicinity of the conditions within the building. 这样的混合或复合空气质量参数信号与现有技术相比可以用于实现各种优点,例如简单性、精确度、成本有效性、以及可靠性。 Such hybrid or composite air quality parameter signal as compared with the prior art may be used to achieve various advantages, such as simplicity, accuracy, cost effectiveness, and reliability. 混合信号还可以如稍后描述独特地使得能够进行新的空气流控制应用,也能够用于通用IEQ监控、命令空气流控制设备、或用于控制与它们有关的建筑物的操作的任何方面,例如结合其HVAC以及建筑物控制系统。 Mixed-signal may also be as described later can be uniquely enables new air flow control applications, can also be used for general IEQ monitoring, command an air flow control device, or to control any aspect of their operation of the building concerned, e.g., combined with its HVAC and building control system. [0022] 关于现有技术的其它方面,针对来自多点空气采样系统的各个空气质量参数的告警或限制功能输出信号在过去有时已经被传送给其它系统,例如建筑物管理系统(BMS),其基于这些功能的状态可以影响建筑物的操作的各个方面,例如到达由多点空气采样系统监控的区域内的位置的空气流等级,其中,监控系统已经检测到单个感测的空气质量参数已经超过预定极限。 [0022] For other aspects of the prior art, the output signal of the alarm or limiting function for each air quality parameter from the multi-point air sampling system in the past may have been transferred to other systems, such as a building management system (BMS), which based on the state of these functions may affect the operation of various aspects of a building, such as the air flow reaches the level position region by multipoint air sampling system monitors within, wherein the monitoring system has detected a single sensing air quality parameter has exceeded predetermined limit. 例如,基于采样的制冷剂监控系统是多点空气采样系统的一个示例,其提供告警/限制功能,例如针对各个参数的告警/限制功能,其中,一个或多个继电器触点(relay contact)或模拟输出信号(例如0_10伏特或4_20毫安信号)在安置了一个或多个共享传感器的地方被本地地提供,或者经由通过数字网络与传感器硬件进行通信的远程模块而被提供。 For example, the sample-based refrigerant monitoring system is an example of multi-point air sampling system, which provides alarm / limit function, such as the various parameters for alarm / limit function, where one or more of the relay contact (relay contact) or The analog output signal (e.g., volts or 4_20 0_10 mA signal) was placed in the one or more shared local sensors is provided locally, or remotely via a digital network by communicating with the sensor hardware is provided. 由BW Technologies的Vulcain分部所制造的VASQN8X多点制冷剂监控器是例如具有这些性能的监控系统的一个示例。 Division of BW Technologies by Vulcain manufactured VASQN8X multi-point refrigerant monitors, for example, has an example of the performance monitoring system. 按照该方式,多点空气采样系统已经被用于提供不连续信号,典型地经由继电器触点,其反过来基于单个空气质量参数提供不连续的控制功能。 In this manner, multipoint air sampling systems have been used to provide a discontinuous signal, typically via relay contacts, which in turn provides a single air quality parameter based on a discontinuous control function. 注意,在本发明的上下文中,不连续信号被定义为具有受限的一组值或状态的信号,例如两状态或三状态以及这些值之间没有中间值或中间状态的阶跃。 Note that, in the context of the present invention, no continuous signal is defined as a signal having a limited set of values or states, e.g., no intermediate values or intermediate step between the two states, and the state or status of these three values. 本发明的上下文中的不连续控制功能相似地被定义为具有受限的一组输出值或状态的信号,例如两状态或三状态并且相似地在这些值之间没有中间值或中间状态的阶跃。 In the context of the present invention, the discontinuous control function similarly is defined as a set value or state of the output signal having a limited, for example, two or three state and a state similar to the intermediate value between these values are not the order or the intermediate state jump.

[0023] 美国专利第5,292, 280号和第5,267, 897号描述了另一种多点空气采样系统,其在多个位置监控单个示踪气体,典型地是二氧化碳(C02),包括回风空气、外部空气、以及与空气处理器关联的送风排出空气,以便直接计算外部空气流成分,用于控制空气处理器。 [0023] US Patent No. 5,292, 280 and 5,267, 897 describes another multi-point air sampling system, which monitors a single tracer gas in multiple locations, typically carbon dioxide (C02), including return air, blowing outside air, and the processor associated with the air exhaust air to the outside air flow directly calculate component for controlling air handler. 该方法使用公共C02或示踪气体传感器和阀,它们被分配给每一采样位置,以提供基于正在被采样的当前位置而在时间上改变的来自C02传感器的复用信号。 This method uses common C02 or tracer gas sensors and valves, which are assigned to each sampling position, to provide based on the current location being sampled on a time change in the multiplexed signal from the sensor C02. 由分离的控制模块来读取来自共享C02传感器的时变信号,在所述分离的控制模块中,基于表示外部空气、回风、 以及送风排出空气C02浓度的序列状态的连续知识来将该时变信号分解为三个分离的C02 或示踪气体信号。 By a separate control module to read the time from the shared sensors C02-varying signal, in the separate control module, based on the outside air shows, return air, and a continuous knowledge of the concentration of the blowing air is discharged C02 sequence state to the time-varying signal is decomposed into three C02 or tracer gas signal separation.

[0024] Warden在题为"SuppIy air C02 Control of minimum outside airfor multiple space system"(David Warden,出版于2004 年10 月,ASHRAE Journal)的论文中所描述的相似的多点空气采样系统现有技术方法应用了公共的单参数C02传感器,使用三向阀或两个分离的双向阀来交替地切换从空气处理器的送风排出空气以及从室外取得的空气采样。 Similar multi-point air sampling system of the prior art [0024] Warden entitled "SuppIy air C02 Control of minimum outside airfor multiple space system" (David Warden, published in October 2004, ASHRAE Journal) described in the paper Application of the common single parameter C02 sensor, using a three-way valve to valve or two separate alternately switched from exhaust air and outdoor air samples taken from the air handler air. 这样便创建了复用信号,所述复用信号可以由计算机以潜在地直接数字控制模块(或DDC 控制器)的形式进行分解,以便得到送风空气C02浓度关于外部空气C02浓度的读数,这反过来可以用于控制进入空气处理器的外部空气。 This creates a multiplexed signal, the multiplexed signal can be decomposed by a computer in order to potentially form of direct digital control module (or DDC controller), so as to obtain the concentration of blowing air on the outside air C02 C02 concentration readings, which in turn can be used to control the outside air entering the air handler.

[0025] Sharp和Desrochers的美国专利第6,609, 967号和第6,790, 136号公开了方法和装置,用于在受控通风环境中安全地再循环空气,以最小化每个房间的通风和热负荷需求, 并且从而降低所需外部空气的量。 [0025] US Patent Sharp and Desrochers first 6,609, 967 and 6,790, 136 discloses a method and device number for safely recycled in a controlled environment in the air ventilation to minimize each room ventilation and heat load requirements, and thus reduce the amount of external air required. 特别地,如果在通风环境的房间之一中感测到一种或多种单个的空气污染物,则从该房间再循环的空气量被减少或潜在地被切断,以防止污染通风环境中的其它房间。 In particular, if one of the ventilation room sensed one or more of the individual air pollutants from the air in the room recirculation amount is reduced or potentially be cut off to prevent contamination airy environment other rooms.

[0026] 其它现有技术系统,例如上述AIRxpert 7000多传感器、多点监控系统、或先前在Sharp的美国专利第6,125,710号中描述的网络化空气采样系统,讨论了测量多个单个的空气质量参数,但仍然没有讨论如何创建或采用来自这些系统的混合空气质量参数信号。 [0026] Other prior art systems, such as the aforementioned AIRxpert 7000 multi-sensor, multi-point monitoring system or networked air sampling system previously in US Patent No. 6,125,710 Sharp described in the discussion of the measurement of a number of individual air quality parameters, but still did not discuss how to create or mixed air from these systems signal quality parameters.

[0027] 此外,迄今为止,使用多个单个的本地传感器来创建来自多个位置的复合信号将涉及用于建筑物管理系统(BNS)或数据获取系统的大量单个的传感器,具有关联的大量先期成本以及大的进行中的校准成本。 [0027] In addition, to date, the use of a plurality of local sensors to create a single composite signal from a plurality of locations will relate to the building management system (BNS) or the data acquisition system of a large number of individual sensors associated with a large number of pre- costs and large ongoing calibration costs. 另一方面,虽然如上所述,多点空气采样系统可以在离散采样和单个的基础上成本有效地感测多个参数,但迄今为止装置一直不能在不连续或连续的基础上合适地组合和混合这些信息使得它能够被有利地应用于适当的监控或控制应用。 On the other hand, although as described above, multi-point air sampling system can be cost-effectively sensing a plurality of parameters in discrete samples and based on the individual, but the device has not so far in the discontinuous or continuous basis on a suitable combination and mixing the information such that it can be advantageously applied to a suitable monitor or control applications.

[0028] 混合空气质量参数信息可以用于明显优点的一个有关应用涉及基于房间或区域的需求控制稀释(DCV)(例如应用于办公室、教室、生产线、礼堂或可变占用空间),或者基于空气处理单元的控制稀释(例如应用于建筑物的空气处理器)。 [0028] A hybrid air quality parameter information about the application can be used to clear the advantages of on-demand room or area involved in the control of dilution (DCV) (for example, used in offices, classrooms, production lines, auditorium or variable space), or on the air Dilution control processing unit (e.g., used in building air processor). 如上所述Warden在题为“Supply air C02 Control of minimum outside air for multiple spacesystems,,的论文中所述,可以通过测量作为C02的用于占用情况和稀释的代理测量(proxy measurement), 基于设施或给定区域或房间中的人数来改变进入设施的外部空气以及进入给定房间或区域的送风量。如上所述,空间或建筑物中的人越多,C02增加得越多,这允许在人数增多时C02的测量驱动和增大进入建筑物的外部空气,如果相反,当空间中人较少时,允许外部空气的量降低。相似地,对于基于房间或区域的需求控制稀释,当区域的C02水平增大时,可以增大进入空间的送风空气,以增大空间中的稀释通风量,反之,当由于空间(例如会议室)中的人减少而C02水平下降时,可以将进入该空间的送风空气降低到处理房间热负荷所需的最小送风空气,以节省能量。 Warden noted above entitled "Supply air C02 Control of minimum outside air for multiple spacesystems ,, the paper in, you can measure for occupancy as C02 and diluted proxy measure (proxy measurement), based on the facility or to the area or room to change given the number of outside air entering the facility and the air volume set to enter a room or area. As mentioned above, space or building more people, C02 increased the more it allows When increasing the number of drivers and increased C02 measurement of outside air into the building, if the contrary, when the amount of human space, allowing reduction in the amount of outside air. Similarly, room or area based demand for control dilution, when the area When the level of C02 increases, the air can be increased air into the space, in order to increase the amount of space in the dilution ventilation, on the contrary, when due to the space (e.g. conference room) and C02 decrease in the level of the person fall into the can blowing air into the space to reduce the processing load required for the minimum heat room air blowing, in order to save energy.

[0029] 虽然基于房间的稀释通风控制和基于空气处理器的外部空气控制的这两个需求控制稀释方法已经被使用了多年,但这些构思的一个问题在于,潜在地存在非人类污染物质,例如微粒、一氧化碳、TVOC(挥发性有机化合物总量)或其它空气污染物,当这些污染物质的源出现并且通风水平很低时,这些污染物质可以累积并且其值增大。 [0029] Although the room based dilution ventilation control based on the outside air and the air handler controls the two demand control dilution method has been used for many years, but a problem with these ideas is that the presence of non-human potentially contaminated materials, e.g. particulates, carbon monoxide, TVOC (total volatile organic compounds) or other air pollutants, when the source of these pollutants and the emergence of low ventilation levels, these pollutants can accumulate and increase its value. 如果例如空间是被稀疏地污染的,并且某些强的和潜在地刺激性清洁剂在空间中被使用,则对于那些现有占用者,由于当现实中清洁剂的存在应该需要高得多的通风等级时占用者的低水平可能已将通风等级向下驱动到低水平,因此问题随之而来。 If for example, the space is sparsely contaminated, and some strong and potentially harsh cleaning agents are used in space, then for those existing occupant, since when there is a real need in the detergent should be much higher When the occupants of the low level of ventilation may have been driven down to the low level of ventilation, so the problem comes. 如由Kurt X. Roth, JohnDieckmann 和James Brodrick 所著的2003 年7 月发表在ASHRAEJournal 上的题为''Demand Control Ventilation"的文章,虽然“实际上DCV已经将每年的能耗降低了每平方英尺0. 05美元到1美元,...当前,多数建筑物并不使用DCV,因为担心前面所述的非人类室内污染物。 '' Demand Control Ventilation "the article, though," as described by Kurt X. Roth, JohnDieckmann and James Brodrick's book was published in July 2003 on ASHRAEJournal entitled DCV consumption has actually reduced the per square foot per year $ 0.05 to $ 1, ... At present, most of the buildings do not use the DCV, for fear of the aforementioned non-human indoor pollutants. (In practice DCV has reduced annual energy cost by$0. 05 to $lper square foot.... Currently, most buildings do not use DCV becauseof concerns about non human indoor pollutants mentionedpreviously·),,。 (In practice DCV has reduced annual energy cost by $ 0. 05 to $ lper square foot .... Currently, most buildings do not use DCV becauseof concerns about non human indoor pollutants mentionedpreviously ·) ,,.

[0030] 除了先前感测这些非人类室内污染物质或空气质量参数的高成本之外,通风控制领域的技术人员尚不知道应该结合自身并非污染物的二氧化碳信息来使用多么不同的空气污染物(例如TV0C、微粒、一氧化碳、和其它污染物),以通过混合使用C02的需求控制稀释加上基于一种或多种空气污染物的稀释通风控制两者的元素来适当地控制进入建筑物的外部空气。 [0030] In addition to these non-human previously sensed indoor air pollutants or costly quality parameters outside, ventilation control is not skilled in the art should know the information itself is not combined with carbon dioxide pollutants how to use different types of air pollutants ( e.g. TV0C, particulates, carbon monoxide, and other pollutants), to use C02 diluted by mixing together the required control of both elements based dilution ventilation control of one or more air pollutants into the building appropriately controlled external air.

[0031] 参照另一工业问题,虽然仅使用上述多点空气采样系统以创建复合或组合的空气质量参数信号存在多个优点,但存在不能通过使用这些多点空气采样系统中的至少一些(若非全部)来被合适地检测到的某些空气质量属性。 [0031] Referring to another industrial problems, although there are several advantages of using only the above-mentioned multi-point air sampling system to create a composite or a combination of air quality parameter signal, but can not exist through the use of these multipoint air sampling system in at least some (if not all) to be appropriately detected some air quality attributes. 最值得注意的是,由于穿过空气采样管道或管子的空气采样的温度将快速把温度改变为等于采样管道或管子的温度,因此不能以中央传感器远程感测温度。 Most notably, since the air passing through the air sampling pipe or tube temperature of the sample quickly to the temperature change is equal to the sampling pipe or tube temperature, and therefore can not be the center sensor remotely sensed temperature. 在很多情况下,在空气温度已经实质上受采样管材的温度影响之前,空气无需传输多于10至20英尺。 In many cases, before the air temperature has substantially affected by the impact of temperature sampling pipe, air without transmission of more than 10 to 20 feet. 此外,还存在其它空气质量属性,例如臭氧或微粒,它们取决于所使用的管材类型或传输速度而可能受通过管材传输的影响。 In addition, there are other air quality attributes, such as ozone or particles, which depends on the type of pipe or the transmission speed is used which may be affected by the pipe transmission. 关于温度,例如,在使用多点空气采样系统测量与水分有关的特性,例如相对湿度和焓时,基于远程传感器的多点空气采样系统欠缺在空气采样位置测量房间或管道温度的能力而产生问题。 On the temperature, e.g., to cause problems in the use of multipoint air sampling system measures moisture related properties, such as relative humidity and enthalpy, the ability to measure the temperature in the room or duct air sampling location based on the multi-point air sampling system lacks remote sensor . 这是因为只能通过多点空气采样系统直接测量绝对湿度、以千分之几的空气中的水蒸气量、或者露点温度。 This is because only through multi-point air sampling system to directly measure the absolute humidity in thousandths of the amount of water vapor in the air, or the dew point temperature. 因而,在空气采样温度受空气采样管材影响之前获得空气采样温度的测量、其后将该温度测量与绝对湿度测量组合或混合的难度在过去阻止了使用这些多点空气采样系统用于在房间中或空气管道中监控或控制相对湿度和焓的混合空气质量参数。 Thus, before the air temperature on the air sampling pipe samples obtained by measuring the temperature of the air sampling, followed by measurement of the temperature measurement and absolute humidity combined or mixed difficulty in the past to prevent the use of these multi-point air sampling systems are used in the room or air duct to monitor or control the relative humidity and enthalpy of mixing air quality parameters.

[0032] 由于所述空气的宽范围的温度及其典型的微粒和灰尘的高浓度,当用作本地传感器时,特别是对于涉及外部空气测量的某些应用,潜在地用于空气处理单元的节能装置中的本地相对湿度和焓传感器难以维持和保持精确性,因此这是潜在地很重要的。 [0032] Since the temperature of the air of a high concentration and a wide range of typical dust particles and, when used as a local sensor, particularly for certain applications involving the measurement of the outside air, potentially for the air handling unit saving means local relative humidity and enthalpy sensors difficult to maintain and keep accuracy, so this is potentially very important. 例如,New BuildingsInstitute进行的对I^acific Northwest中的节能装置和空气处理单元的的最近的研究表明,大约三分之二的节能装置被评估为没有适当地工作,或在由于传感器故障而导致在很多情况下完全失效。 For example, New BuildingsInstitute performed on I ^ acific Northwest Energy Saving device and an air handling unit, recent studies have shown that approximately two-thirds of the energy saving device is evaluated to be not properly work, or due to sensor failures in completely ineffective in many cases.

[0033] 为了更详细地解释该应用,本发明上下文中定义的节能装置是存在作为建筑物空气处理系统的一部分的系统,用于通过引入外部空气代替或辅助机械制冷(例如基于机械设备的空调)来减少制冷成本。 [0033] In order to explain in more detail the application, power saving device as defined in the context of the present invention is present in the system as part of a building air handling system for the introduction of outside air in place of or assisted mechanical refrigeration (e.g., based on mechanical air conditioning equipment ) to reduce cooling costs. 节能装置的有效性很大程度上基于当外部空气条件适合从而外部空气可以用于所谓的“自由制冷”以减少压缩机使用时的感测能力。 Effectiveness is largely based on energy saving device when outside air conditions are suitable so that outside air can be used for so-called "free cooling" to reduce the sensing capability of the compressor when used. 美国专利第4,182,180号和第4,570,448号公开了使用外部空气来用于制冷的示例性技术,通过引用将这些专利并入本文中。 U.S. Patent No. 4,182,180 and No. 4,570,448 discloses the use of outside air to exemplary techniques for refrigeration, these patents are incorporated by reference herein. 它包括基于干球温度、单个焓、以及差分焓的节能装置。 It consists on a dry bulb temperature, single enthalpy and differential enthalpy economizers. 在这些类型的节能装置中,基于焓的类型(具体地说,基于差分焓的节能装置)已经显示出较好性能,尤其在更热的更潮湿的气候中,其中,与制冷外部空气关联的潜热负荷(latent heat load)可以是一个重要因素。 In these types of energy-saving devices, based on the enthalpy of the type (specifically, the economizer means differential enthalpy) have shown better performance, especially in the hotter and more humid climates, which is associated with the cooling outside air latent heat load (latent heat load) may be an important factor. 对于该应用,焓传感器可用于节能装置,例如Honeywell型号C7650固态节能装置控制。 For this application, the enthalpy sensor apparatus can be used for energy saving, such as Honeywell Model C7650 solid state saving means controls.

[0034] 虽然以基于焓的节能装置的节省潜力可以是显著的,但上述这些系统通常在实践中部分地由于不可靠的传感器技术的问题而导致实现受限的节能,这是本领域所公知的。 [0034] Although the potential savings based on energy saving device enthalpy may be significant, but these systems are usually in practice in part because of the problem is not reliable sensor technology and leading to limited energy, as is known in the art a. ASHRAE(美国采暖、制冷、和空调工程师协会)已经评价了这些传感器的有限的可靠性,例如在ASHRAE标准90. 1用户手册中。 ASHRAE (American Society of Heating, Refrigerating, and Air Conditioning Engineers) has evaluated the limited reliability of these sensors, such as ASHRAE Standard 90.1 User's Manual. 已知的焓传感器基于塑料丝,其会随时间而恶化,导致故障或总的校准误差。 Known enthalpy sensor plastic wire, which will worsen with time-based, resulting in a total failure or calibration error. 较新的传感器基于固态设计,但它们仍然遭受漂移和可重复能力的问题。 The sensor is based on the newer solid-state design, but they still suffer from the problem of drift and repeatability.

[0035] 中央远程绝对湿度和冷镜湿度计精确、可靠的多,并且当作为多点空气采样系统的一部分时被成本有效地使用。 [0035] remote central chilled mirror hygrometer absolute humidity and accurate, more reliable, and when used as part of a multi-point air sampling system is effectively the cost. 如果本地温度测量的方面可以被成本有效地解决,则这些传感器可以有利地用于相对湿度和焓的更常用的测量。 If the aspect local temperature measurement can be cost-effectively solve, these sensors may advantageously be used more commonly measured relative humidity and enthalpy.

[0036] 节能装置的另一问题在于,存在室外条件劣于室内条件的时间,例如在高峰时段期间位于主要公路附近的建筑物。 [0036] Another problem is that the energy-saving devices, outdoor conditions inferior to indoor conditions, the existence of time, such as during peak hours is located in a building near the main road. 在这些时间段期间,如果节能装置要求自由制冷,则潜在地100%外部空气被抽入建筑物中,这可以节省能量,但是由于建筑物外部的高交通流量, 设施的室内空气质量可能实际上变得更糟。 During these time periods, if the energy saving devices require refrigeration freedom is potentially 100% outside air is drawn into the building, which can save energy, but due to high traffic outside the building, facilities, indoor air quality may actually worse. 结果,将有助于能够创建混合外部空气污染物信号,其包括多种空气污染物,例如TV0C、C0、以及潜在地包括微粒,它们可以用于空气处理器,以当外部空气“很脏”时,强制覆盖(override)外部空气的节能装置控制。 As a result, will help to create a mixed signal outside air pollutants, which include a variety of air pollutants, e.g. TV0C, C0, and potentially including microparticles, they can be used for an air handler, when the outside air to the "dirty" When mandatory coverage (override) outside air economizers control.

[0037] 使用空气污染物传感器(例如用于微粒、CO、TV0C、或其他空气污染物的传感器) 的建筑物中的稀释通风的一个已知问题在于,如果外部空气浓度变得足够高,则增大进入受控区域或房间的外部空气或送风空气的空气流量将实际上增大空间、管道、或空气处理器中的所感测的空气污染物水平。 [0037] The use of air pollutants sensors (e.g. for particulates, CO, TV0C, or sensors of other air pollutants) dilution ventilation of buildings a known problem is that, if the external air concentration becomes sufficiently high, then increases enters the controlled area or room air or outside air air flow rate will actually increase the levels of air pollutants sensed space, duct, or air processor. 当超过内部稀释通风阈值水平时,这可以潜在地创建负反馈情形,迫使外部空气水平和/或房间送风空气流水平达到其最大水平。 When the internal dilution ventilation exceeds the threshold level, which could potentially create negative feedback case, forcing the level of the outside air and / or room air supply air flow level reaches its maximum level. 取决于HVAC系统的设计容量的水平,在这种锁闭情况下,可能超过空气处理系统的容量,导致HVAC系统控制的性能降低。 Depends on the level of the design capacity of the HVAC system, in this case locked, may exceed the capacity of the air handling system, resulting in reduced HVAC system control performance.

发明内容 SUMMARY

[0038] 因此,本发明的主要目的在于提供一种系统,用于至少部分地使用多点空气采样系统并且在某些情况下还使用本地离散空气质量参数传感器,提供从各个空气质量参数测量推导出的混合空气质量参数测量。 [0038] Accordingly, a primary object of the present invention is to provide a system for, at least in part, using multi-point air sampling system and also uses discrete local air quality parameter sensors in some cases, provided from the respective air quality parameter measurements derived out of the mixed air quality parameter measurements.

[0039] 本发明的另一目的在于提供一种系统,用于提供精度和成本有效性改进的空气质量参数测量,这在仅使用离散本地传感器或仅使用多点空气采样系统的情况下无法实现。 [0039] Another object of the present invention is to provide a system for providing an improved accuracy and cost effectiveness of the air quality parameter measurement, which can not be achieved in the case where only the discrete sensors or only local multi-point air sampling system .

[0040] 本发明的另一目的在于提供一种系统和方法,用于提供用于控制建筑物HVAC(加热、通风、以及空调)操作和包括控制设备的设备的一种类型的成本有效且精确的混合空气质量参数传感器测量,这在过去一般无法实现。 [0040] Another object of the present invention is to provide a system and method for providing a building for controlling the HVAC (heating, ventilation, and air conditioning) and one type of operating control apparatus comprising the device cost-effective and accurate The mixed air quality parameter sensor, which is generally not possible in the past. 本发明的另一个目的在于使得能够进行具体控制和监控应用,其涉及创建相对湿度和/或焓的混合空气质量参数测量,利用本发明能够更加成本有效且精确地进行上述操作。 Another object of the present invention is to enable specific control and monitoring applications, which involves creating relative humidity and / or air quality parameters measured enthalpy of mixing, the use of the present invention can be more cost-effectively and accurately perform the above operation.

[0041] 本发明的另一目的在于使得能够进行改进的和更健康的形式的需求控制稀释,其涉及创建和使用改进的外部空气控制信号和/或送风空气流控制信号。 [0041] Another object of the present invention is to enable improved and healthier in the form of demand control dilution, which involves the creation and use of improved outside air control signal and / or blowing air flow control signal. 这些控制信号也被称为外部空气命令信号和/或稀释通风命令信号,可以例如使用混合空气质量参数信号来进行创建,所述混合空气质量参数信号可以典型地包括二氧化碳水平信息的各个方面,以实现需求控制稀释的各个方面;以及来自至少一个其它空气质量参数测量(例如TV0C、微粒、一氧化碳、或甚至湿度)的信息,以辅助通过以下操作来保持空间或建筑物中的良好的空气质量:将适当水平的送风空气流提供给空间,和/或提供进入建筑物的外部空气,以将任何这样的所感测的空气污染物稀释下降到安全或推荐的水平。 These control signals are also referred to as outside air command signal and / or the dilution ventilation command signal, for example, using the combined air quality parameter signal to be created, the mixed air quality parameter signal may typically include information on various aspects of carbon dioxide levels in implement various aspects demand control dilution; and information from the at least one other air quality parameter measurements (e.g. TV0C, particulates, carbon monoxide, or even humidity) to assist the operation by space or building to maintain good air quality in: The space available for an adequate level of air flow of air, and / or to provide outside air entering the building, to dilute any such sensed air pollutants down to safety or the recommended level.

[0046] 在本发明的上下文中,上述建筑物控制系统或建筑物管理系统被定义为位于建筑物或设施中的控制系统,其用于控制建筑物中的HVAC系统的一个或多个功能,例如控制空间温度、空间相对湿度、空气处理单元空气流和操作、排风机流、冷却操作、节能装置操作、 管道静压、建筑物加压、风险环境空气流。 [0046] In the context of the present invention, the above-described building control systems or building management system is defined as a building or facilities located in the control system, for one or more of the functions in the building HVAC system control, such as space temperature control, space relative humidity, air flow and air handling unit operation, exhaust fan flow, cooling operation, energy-saving operation of the device, static pressure pipeline, building pressurization, air flow risk environment. 这些系统经常集成有或包括有其它建筑物系统或子系统,例如着火和安全系统、卡访问系统、闭路电视监控系统、烟控制系统、电源监控系统、跟踪空气流控制系统、和风险环境空气流控制系统。 These systems are often integrated with or include other building systems or subsystems, such as fire and security systems, card access systems, CCTV surveillance systems, smoke control systems, power monitoring systems, tracking air flow control system, and the risk of ambient air flow control system. 建筑物控制系统可以具有气动、电力、电子、微处理器、计算机或基于web的控制,其使用气动信号、模拟信号和/或数字信号输入和输出。 Building control systems may have pneumatic, electrical, electronics, microprocessors, computer or web-based control, the use of a pneumatic signal, analog and / or digital signal inputs and outputs. 这些系统经常具有中央监控功能、中央控制性能或本地控制性能,并可以具有基于因特网或web的访问。 These systems often have a central monitoring function, the central control or local control performance properties, and may have access to the Internet or web-based. 它们还可以被称为建筑物管理系统(BMS)、设施控制系统(FCS)、或设施管理系统(FMS)。 They can also be referred to the Building Management System (BMS), facility control system (FCS), or facility management system (FMS).

[0047] 本发明的另一目的在于提供系统和方法,用于防止稀释通风和外部空气流控制由于高室外空气污染物水平而变成锁闭在高流等级。 [0047] Another object of the present invention to provide a system and method for preventing outside air dilution ventilation and outdoor air flow control due to the high levels of contaminants and become locked in the high flow grades. 对于外部空气控制解决该问题的优选实施例涉及使用用于控制的混合空气污染物信号,其从取得室内对室外污染物水平的差分而不是绝对室内水平而被创建。 For the outside air is preferably controlled to solve the problem using the mixed signal is used to control air pollutants involves the implementation of the embodiment, obtained from the indoor to outdoor its contaminant level difference rather than absolute indoor levels are created. 由于以相同传感器来进行室内和室外测量实质上减小了当获取两个不同传感器之间的差时被典型地放大的一般传感器误差,因此使用多点空气采样系统提供了独特的高精确度来使得该应用成为可能。 Since the same sensor for indoor and outdoor measuring substantially reduced when acquiring the difference between the two different sensors are typically amplified general sensor error, and therefore the use of multipoint air sampling system provides a unique high degree of accuracy The application makes it possible. 同样,用于对于基于房间的稀释通风控制解决该问题的优选实施例涉及使用用于控制的混合空气污染物信号,其通过使用共享传感器空气采样系统而被创建,所述空气采样系统使用馈送受监控的区域或空间的送风空间中的污染物水平与区域或空间污染物水平的测量之间的差来生成差分空气污染物信号。 Similarly, for the control room based dilution ventilation preferred solution to this problem using the mixed signal is used to control air pollutants involves the implementation of the embodiment, which is created by an air sampling system using a shared sensor, said air sampling system by feeding the difference between the level and regional level space measuring pollutants or contaminants air space surveillance in the area or space between the signal to generate a differential air pollutants.

[0048] 近来,当由信号处理控制器要使用多个空气质量参数来帮助创建稀释通风或外部空气流命令信号时,尤其在每个空气质量参数具有关注的不同阈值的情况下,每个空气质量参数可以被比例缩放为相对于该阈值的标准比例。 [0048] Recently, when the signal processing controller to be used by a plurality of air quality parameters to help create a dilution ventilation or outside air flow command signal, especially in the case of each air quality parameter concerned having different threshold value, each air quality parameter may be a standard proportional scaling with respect to the threshold. 例如,0至10伏特范围中的2伏特可以表示空气流应该开始被增大的阈值点,而10伏特表示最大流。 For example, 0-10 Volts 2 volts may represent the air flow should be increased start threshold point, and 10 volts represents the maximum flow. 于是,可以高选择单个的信号,从而这些信号中的较高的信号控制稀释流。 Thus, you can select a single high signal, so that these signals in a higher signal to control the dilution flow. 作为替换方案,在信号已经基于每一感测的化合物的健康影响的严重性或基于先前阈值的加权以相对方式被加权之后可以对它们求和。 As an alternative, the severity of the signal has been sensed based on the health effects of each compound or weighting a previous threshold relative manner can be based on a weighted sum them after. 在以下情况下也可以使用非线性加权:例如超过阈值的增大水平的危险污染物要求高得多的空气流例如对于一氧化碳,相对于更良性的但仍然重要的污染物例如微粒。 In the following cases can also use non-linear weighting: e.g., exceeds the threshold level is increased much higher risk of contamination of the air flow requirements of for example carbon monoxide, with respect to the more benign but still significant contaminants such as fine particles.

Scanivalve. You can see the com, which uses pneumatic selector switch and the stepper motor to the plurality of input ports is connected to the outlet port, the outlet port may be connected to a sensor such as a pressure sensor or the like. 螺线管阀161至167被控制逻辑110控制为按照一种顺序进行切换。 Solenoid valves 161-167 control logic 110 is controlled to be switched in accordance with an order. 所述顺序可以是一个螺线管接一个螺线管的简单顺序模式,或者是例如通过编程而改变为潜在的多个预设定模式中的一个,或者它可以具有这样的模式:所述模式可以通过手动或远程命令、或通过基于一种或多种感测的空气质量参数的值或信号模式的触发事件,从而被中断并且改变为新的顺序。 The order may be connected to a solenoid of a solenoid simple sequential mode, or for example, by changing the programming of a plurality of potential modes of a preset, or it may have a mode: the mode can thus be interrupted by a manual or remote command, or by a value based on a triggering event or signal pattern of one or more sensed air quality parameters, and changing to the new order. 所述触发事件可以从多点空气采样系统100的外部生成,也可以从信号处理控制器块130所处理的传感器信息创建。 The triggering event from an external multi-point air sampling system 100 generates, you can create a sensor information processing signal processing controller block 130 from.

[0067] 螺线管阀161至167通过管材14、24A、44A、44B、54B、24C和64连接到空间中的采样位置13、23A和23C、以及管道感测位置43A、43B、5!3B和63。 [0067] solenoid valves 161 to 167 through the pipe 14,24A, 44A, 44B, 54B, 24C and 64 connected to the sample location space 13,23A and 23C, as well as position sensing pipe 43A, 43B, 5! 3B and 63. 在图1中,例如,走廊10中的采样位置13通过管材14连接到螺线管161。 In Figure 1, for example, the sampling positions corridor 10 to the solenoid 13 is connected via tubing 14 161. 房间20A和20C中的区域感测位置23A和23C通过管材24A和24C分别连接到螺线管162和166。 20A and 20C in the room area sensed position 23A and 23C are respectively connected via tubing 24A and 24C to the solenoids 162 and 166. 回风管道采样位置43A和回风传送管道采样位置4¾通过管材44A和44B分别连接到螺线管163和164。 Return air duct sampling location and return air delivery duct 43A sampling location 4¾ are connected to the solenoid 163 and 164 through the pipes 44A and 44B. 送风管道采样位置5¾通过管材54B连接到螺线管165。 Air duct sampling location 5¾ through pipes connected to the solenoid 165 54B. 最后,外部空气管道采样位置63通过管材64连接到螺线管167。 Finally, the outside air duct sampling location 63 is connected to the solenoid 167 via tubing 64. 作为替换,管材64可以连接到除了管道60之外的一些其它合适的位置,以获得外部空气采样。 Alternatively, pipe 64 may be connected to the pipe 60 in addition to some other suitable location, to obtain external air sampling.

[0068] 上述管材将空气采样从感测位置传输到多点空气采样系统100的螺线管。 [0068] The air sampling pipe will be transferred from the sensed position to the solenoid multi-point air sampling system 100. 所述管材在直径上典型地具有八分之一到二分之一英寸的内径,优选的内径是大约四分之一英寸。 The tubes typically have a diameter in the one-eighth to one-half inch inside diameter, the inner diameter is preferably about one-quarter inch. 所述管材可以用标准塑料气管(pneumatic tubing)或本领域技术人员所知的其它合适的管材来制成,所述标准塑料气管材例如NJ的Mirling的ThermoplasticProcesses有限公司制作的,Dekoron TM低密度聚乙烯(LDPE)塑料、聚四氟乙烯、不锈钢的“Bev-A-Line XX”管材。 The tubing can be other suitable pipe with standard plastic tubing (pneumatic tubing) or known to those skilled in the art to be made, such as the standard plastic gas pipe Mirling of ThermoplasticProcesses NJ Limited production, Dekoron TM low-density polyethylene Ethylene (LDPE) plastic, Teflon, stainless steel "Bev-A-Line XX" pipe. 然而,为了在传输TVOC和微粒中的较优性能,对VOC呈惰性而具有很少的吸收和解吸附的、并且导电以防止静电累积的材料是优选的,例如柔性不锈钢管材。 However, for optimum performance in transmission TVOC and microparticles, of VOC inert and has little absorption and desorption, and the conductive material to prevent the accumulation of static electricity is preferred, e.g., a flexible stainless steel pipe. 在2004年9月23 日提交的题为“TUBING FORTRANSPORITNG AIR SAMPLES IN AN AIR MONITORINGSYSTEM” 的美国专利申请序列号第10/948,767号以及在2005年6月10日提交的题为“Α^ MONITORING SYSTEM HAVINGTUBING WITH AN ELECTRICALLY CONDUCTIVE INNERSURFACE FOR TRANSPORTING AIR SAMPLES”的美国专利申请序列号第11/149,941号中描述了其它优选材料和构造。 Entitled September 23, 2004 filed "TUBING FORTRANSPORITNG AIR SAMPLES IN AN AIR MONITORINGSYSTEM" US Patent Application Serial No. 10 / 948,767, and in June 10, 2005 filed entitled "Α ^ MONITORING SYSTEM HAVINGTUBING WITH AN ELECTRICALLY CONDUCTIVE INNERSURFACE FOR TRANSPORTING AIR SAMPLES "US Patent Application Serial No. 11 / 149,941 describes other preferred materials and construction.

[0069] 此外,在图1中,真空泵140通过管材将空气从感测位置吸入螺线管161至167以及吸入集气管(manifold) 190,所述集气管190将螺线管的所有输出端口连接在一起,并将它们连接到共享传感器120的入口。 [0069] Further, in FIG. 1, the vacuum pump draws air into the pipe 140 through the solenoid 161 to 167 and all output ports connected to a suction manifold (manifold) 190, the solenoid of manifold 190 from the sensing position together, and connect them to the inlet 120 of the shared sensor. 共享传感器120的出口由管材141连接到真空泵,所述管材141的构造并不关键,并且可以是不昂贵的塑料管材,例如上述的Dekoron TM或其它管材。 Shared outlet pipe 141 by the sensor 120 is connected to a vacuum pump, the tube structure 141 is not critical, and may be an inexpensive plastic tubing, such as described above Dekoron TM or other pipe. 所述管材的内直径可以做成与连接到螺线管阀的入口的管材的尺寸相似,或可能为了较少的压降因而做得更大。 Similar to the internal diameter of the pipe can be made with a solenoid valve connected to the inlet pipe size, or the pressure drop and thus less likely to be made larger. 共享传感器120可以包括一个或多个传感器,用于测量空气舒适参数,例如绝对湿度或露点温度、二氧化碳;非空气质量参数,例如差分静压;或空气污染物,例如C0、微粒、烟、TV0C、感兴趣的特定V0C、甲醛、NO、Ν0Χ, S0X、氮氧化合物、氨、 制冷气体、氡、臭氧、生物和/或化学恐怖活动制剂、霉菌、其它生物制剂、以及待感测的感兴趣的其它空气污染物。 Shared sensor 120 may include one or more sensors, for measuring the air comfort parameters, such as dew point temperature or absolute humidity, carbon dioxide; non-air quality parameters, e.g., differential static pressure; or air pollutants, e.g., C0, particulates, smoke, TV0C , and interest to be sensed, specific V0C interest, formaldehyde, NO, Ν0Χ, S0X, nitrogen oxides, ammonia, refrigerant gases, radon, ozone, biological and / or chemical terrorist agents, mold, other biologicals other air pollutants. 这些传感器可以串联、并联、或串联和并联组合连接。 These sensors can be connected in series, parallel, or connected in series and parallel combinations.

[0070] 共享传感器120的信号输出被传递到多点空气采样系统100的信号处理控制器块130。 [0070] Sharing the sensor signal output 120 is transmitted to the multipoint air sampling system 100 of the signal processing controller block 130. 该块130还从传感器输入块150接受其它传感器信息。 The block 130 also receives information from other sensors, sensor input block 150. 该输入块150根据需要或期望从本地房间或管道传感器而不是远程传感器接受传感器信号或信息。 The input block 150 to accept the sensor signals or information from the local room or duct sensor instead of the remote sensor as needed or desired. 例如,由于空气的温度将随着其移动通过管材而快速变化为管材的温度,因此不能远程感测温度。 For example, since the temperature of the air as it moves through the pipe will change rapidly as the temperature of the pipe, and therefore can not remotely sensed temperature. 此外,某些区域可能需要对空气质量参数的即时的感测。 In addition, some areas may require immediate sensing of air quality parameters. 这在房间20A中示出,其中房间传感器25A 通过电缆26A连接到传感器输入块150,所述房间传感器25A例如可以是温度传感器。 This is shown in the room 20A, 25A which room sensor 26A is connected via a cable to the sensor input block 150, the room sensor 25A may for example be a temperature sensor. 如果对于25A使用温度传感器,并且位于采样入口23A附近,则可以将该位置的共享传感器绝对湿度或露点温度测量与来自传感器25A的温度测量进行组合或混合,以创建非常精确的对相对湿度、焓或其它有关的干湿测量之一的成本有效的测量。 If the temperature sensor is used for 25A and is located near the entrance of the sample 23A, the shared sensor location can be an absolute humidity or dewpoint temperature measurement and temperature measurement from the sensor 25A may be combined or mixed to create a very precise relative humidity, enthalpy or one of the other costs related to the measurement of wet and dry valid measurement. 类似地,如果外部空气管道传感器65被用于测量温度,则来自采样位置63的共享传感器绝对湿度测量或露点温度测量的组合将允许计算相对湿度或焓的外部空气测量,其中所述采样位置63的位置可以接近于传感器位置65。 Similarly, if the sensor 65 is outside air duct for measuring the temperature, the sampling position from the absolute humidity sensor 63 is shared measurement or a combination of dew point temperature measurements would allow the calculation of the relative humidity of the outside air or enthalpy measurement, wherein said sampling position 63 The position can be close to the sensor position 65.

[0071] 传感器和传感器输入块可以利用多种信号形式工作,例如模拟电压、模拟电流、或数字。 [0071] Sensors and sensor input block can use a variety of signals in the form of work, such as analog voltage, analog current, or digital. 作为替换方案,传感器可以具有其自己的板载(on board)微处理器,并通过数据通信协议与传感器输入块150通信,所述数据通信协议例如是Echelon公司的LonTalk、或ASHRAE's BACnet通信标准所概述的合适的协议、或实际上任意其它合适的协议,包括各种专有协议和常用于提供建筑物环境内的设备之间的数据通信的其他工业标准协议。 As an alternative, the sensor may have its own on-board (on board) microprocessor, and a data communication protocol through the communication 150 with the sensor input block, the data communication protocol, for example, Echelon's LonTalk, or ASHRAE's BACnet communication standard appropriate protocol outlined or indeed any other suitable protocols, including commonly used in a variety of proprietary protocols and other industry standard protocols provide data communication between devices within a building environment. 然而, 典型地,当使用数字数据通信来连接到离散设备,例如25A时,使用在物理层(例如EIA 485 物理层)上运行的协议来实现这种操作,在所述物理层的顶部将使用合适的上层协议。 Typically, however, when using the digital data communication to connect to the discrete devices, such as 25A, use the physical layer (e.g., EIA 485 physical layer) protocol running on to achieve this operation, will be used on top of the physical layer right upper-layer protocols. 在这些情况下,例如,电缆26A可以被指定为双绞线屏蔽导线对。 In these cases, for example, the cable 26A can be designated as shielded twisted wire pair. 尽管如此,可以使用对建筑物控制产业常用的任意数量的电缆类型来实现传感器25A与输入块150之间的连接。 Nevertheless, you can use the connection 150 between the building control any number of conventional industrial cable types to achieve the sensor 25A and the input block. 此外, 可以省略电缆26A,并且传感器25A可以使用诸如IEEE 802. lla/b/g、Zigbee、Bluetooth、 网状网络(mesh networking)之类的协议和方法,或者用于建筑物和IT(信息技术)工业中的其他无线方法,与输入块150进行无线通信。 In addition, you can omit the cable 26A, 25A and the sensor can be used, such as IEEE 802. lla / b / g, Zigbee, Bluetooth, mesh networking protocol and methods (mesh networking) and the like, or for buildings and IT (information technology ) industry other wireless methods, with an input block 150 performs wireless communication.

[0072] 使用信号处理控制器块130来处理来自共享传感器的传感器信息,以创建反映所感测的位置中的环境状况的虚拟传感器信号。 [0072] Using the signal processing controller block 130 to process the sensor information from the shared sensors, to create the virtual sensor signal measuring the position of the reflection of the sensed environmental conditions. 该信息被添加到来自任何本地房间传感器(例如25A)或管道传感器65的信息,然后可以被进一步处理以创建混合的或复合的空气质量参数信号,然后以各种可能的方式被使用。 This information is added to or pipe sensor information from any local room sensor (eg 25A) 65, and can be further processed to create a hybrid or composite air quality parameter signals, and then be used in every possible way. 例如,为了监控和/或控制的目的,可以通过数字网络化的连接181将该信息发送到建筑物控制系统180。 For example, for the purpose of monitoring and / or control 181 can be connected to the information sent to the building control system 180 through the digital networked. 例如可以使用BACnet协议、 Lonworks, 0PC、XML数据交换或其它合适的接口信息转换来进行信息交换。 For example you can use the BACnet protocol, Lonworks, 0PC, XML data exchange or other appropriate conversion interface information to exchange information. 物理连接181 可以是以太网连接、EIA 485(也称为RS480连接、或其它类型的数字数据通信连接。数据的另一使用可以是通过内部局域网和/或外部局域网或广域网将其发送,以在远程位置进行监控。此外,数据可以直接地或通过局域网而穿过电话网络或其它合适的连接装置171, 以连接到因特网或专用网络,可以从所述因特网或专用网络使用网站或其它合适的装置来远程访问、显示、和分析来自多点空气采样系统100的数据。 Physical connection 181 may be an Ethernet connection, EIA 485 (also known as RS480 connection, or other types of digital data communication connection to another data may be used by the internal LAN and / or an external LAN or WAN, send it to the remote location to be monitored. Additionally, the data can be directly or through a local area network and through the telephone network or other suitable attachment means 171, to connect to the Internet or a private network, the site may be used or other suitable means from the Internet or a private network to remote access, display, and analyze data from multi-point air sampling system 100.

[0073] 最重要的是,信号处理控制器块130还可以提供房间空气流控制器30所使用的控制信号31,以及稀释通风命令信号31A、31B和31C,其中所述房间空气流控制器30在图1 中被示出为块30A、30B和30C。 [0073] Most importantly, the signal processing controller block 130 may also provide room air flow controller 30 used by the control signal 31, and the dilution ventilation command signal 31A, 31B and 31C, wherein said room air flow controller 30 In Figure 1 is shown as blocks 30A, 30B and 30C. 控制信号31用于动态改变空间的最小送风空气流等级,其也等同地控制房间20A、20B和20C的稀释通风的量。 Control signal 31 for dynamically changing the minimum air space air flow level, which is also equivalent to the control room 20A, 20B and 20C of the amount of dilution ventilation. 由于可以由共享传感器所感测的空气质量参数中的一个是二氧化碳,因此混合稀释通风命令信号还可以包括与给定空间中的二氧化碳水平有关的信息,用于实现对变化的占用情况进行响应的本地房间水平需求控制通风方法。 Since the sensor can be shared by the sensed air quality parameter a is carbon dioxide, mixing dilution ventilation command signal may also include information relating to the carbon dioxide level in a given space, for implementing changes in occupancy of responding local the level of demand control room ventilation methods. 并且,给定与房间空气流控制器30关联的电子器件的柔性特性,可以在房间空气流控制器30内执行由信号处理控制器130执行的部分或全部功能,所述房间空气流控制器30可以是可编程设备。 And, 30 associated with a given room air flow controller of the flexible nature of the electronic device, may perform some or all of the functions performed by the signal processing controller 130 in the room air flow controller 30, the room air flow controller 30 may be a programmable device. 在此情况下,可以在控制器30内至少部分地创建信号31。 In this case, the signal 31 can be created within the controller 30 at least partially.

[0074] 参照稀释通风命令信号31A、31B、31C,信号处理控制器块130可以产生这些信号或这些信号的一些部分,或者全部或一部分控制功能可以由建筑物控制系统180产生。 [0074] Referring dilution ventilation command signals 31A, 31B, 31C, the signal processing controller block 130 may generate these signals or portions of these signals, or all or part of the control functions can be generated by the building control system 180. 例如在图2中示出这种情况,其中稀释通风命令信号31C使用来自图2中的共享传感器220和/或本地房间传感器(例如^C)的传感器信息,特别是空气质量参数传感器信息。 For example in Figure 2 illustrates such a situation, in which the dilution ventilation command signal 31C in Figure 2 using the sensor information from the shared sensors 220 and / or a local room sensors (e.g. ^ C), in particular air quality parameter sensor information. 进一步地,应该清楚,图1的信号处理控制器130、图2的信号处理控制器210、或图6的信号处理控制器1130无需分别被物理地封装在块100、200或1100内,并且能够将信号处理控制器130、210或1130实现为单机模块,或将它们与例如图1、图2或图6内示出的某些其它部分或系统集成在一起。 Further, it should be clear, the signal processing controller 130 of FIG. 1 signal processing, signal processing controller of Figure 2 the controller 210, or 1130 in FIG. 6, respectively, without being physically encapsulated within the block 100, 200 or 1100, and can be The signal processing controller 130,210 or implemented as a stand-alone module 1130, or they may be integrated with the example in Fig. 1, Fig. 2 or some other part or system 6 is shown.

[0075] 参照图2,该图涉及本发明的另一优选实施例,其针对于使用网络化空气采样系统(例如与美国专利第6,125,710号中所描述的相似的空气采样系统)来创建混合或复合空气质量参数测量以及稀释通风空气流命令信号。 [0075] Referring to Figure 2, this figure relates to another preferred embodiment of the present invention, which directed to the use of networked air sampling system (e.g., similar to air sampling systems and U.S. Patent No. 6,125,710 described above) to create hybrid or composite air quality parameter measurements and dilution ventilation air flow command signal. 这种采样系统具有许多种功能,并且与图1 所指示的系统相似,主要差别在于,螺线管开关和一些控制分布在建筑物中的各个地方,而不是位于一个中央单元中。 This sampling system has many functions and is similar to the system indicated in Figure 1, the main difference is that some of the solenoid switch and control the distribution of the various places in the building, rather than in a central unit. 结果,图1所示的中央采样单元100被传感器和控制单元200 连同分布式空气和数据路由器300A、300B、300C和300D有效地替代。 As a result, the central sampling unit 100 is shown in 200, together with air and distributed data routers 300A, 300B, 300C and 300D in Figure 1 effectively replace the sensor and control unit. 由信号处理控制器块210来处理信号处理功能和系统的序列化控制。 By signal processing controller block 210 to process the sequence control and signal processing functions of the system. 块210执行图4中的块510和530的功能, 稍后对其进行描述。 4 in block 510 and block 210 in FIG execution function 530, be described later. 共享传感器块220执行与图4的块520或图1的块120相同的功能。 Shared sensor block 220 performs the same functionality as in Fig. 4 block 520 or block 120 of FIG.

Adding these conductors enables local sensors can be more easily and more cost effectively added to the system.

[0077] 例如,采样位置23A、以及其它采样位置43A、43B、53B、24C和63也可以包含本地温度传感器,以感测房间或管道温度,所述本地温度传感器与被集成到采样位置中的本地传感器25A相似。 [0077] For example, sampling location 23A, and the other sampling positions 43A, 43B, 53B, 24C and 63 may also comprise local temperature sensors to sense the temperature of the room or duct, and the local temperature sensor is integrated into the sampling position Local sensor 25A similar. 可以把来自该温度传感器或来自其它本地传感器(例如湿度传感器、臭氧传感器)的信号,或其它本地空气质量参数特性通过数据通信电缆(例如双绞线、屏蔽双绞线、光纤光缆)或其它数字数据通信介质发送到空气数据路由器300,作为数字数据通信信号。 Can be a signal from the temperature sensor or sensors from other local (e.g., a humidity sensor, ozone sensor), or other local air quality parameter characteristics via the data communication cable (e.g., twisted pair, shielded twisted pair, fiber optic cable), or other digital transmitting the data communication medium to the air data router 300, as digital data communication signals. 作为替换,可以通过一个或多个信号导体经由模拟信号将传感器信息发送到路由器300,作为模拟电压或电流信号。 Alternatively, can be sent via one or more signal conductors via the analog sensor signal information to the router 300, as an analog voltage or current signal. 其后,可以由路由器300A或300B中的1/0块320A或320B分别将这个模拟信号转换为数字信号。 Thereafter, router 300A or 300B may be formed in a 1/0 block 320A or 320B, respectively, the analog signals into digital signals.

[0078] 这些I/O块320A和320B还可以监控其它空气质量参数或信号输入,所述信号输入可以与也可以不与空气采样入口直接关联,但将具有数据通信电缆、模拟信号电缆、或对I/O块的其它连接。 [0078] The I / O blocks 320A and 320B may also monitor other air quality parameters or signal input, the signal input may or may not be directly associated with the air inlet and the sample, but will have a data communication cable, analog signal cable, or for I / O blocks other connections. 这些传感器中的一个的示例是房间传感器27A,其可以是温度传感器、 空气质量参数传感器、或其它类型的传感器,例如光学传感器、差分压力传感器、空气速率传感器、或其它建筑物传感器,例如占用传感器或占用开关,或甚至其他类型的某种类型的开关,比如本地房间开关81。 Examples of these sensors is a room sensor 27A, which may be a temperature sensor, an air quality parameter sensor, or other types of sensors, such as optical sensors, differential pressure sensors, air velocity sensors, or other building sensor, occupancy sensor e.g. or occupancy switch, or even other types of certain types of switches, such as the local switch 81 rooms. 在后者的传感器或房间开关中,占用传感器在本发明的上下文中被定义为这样一种传感器:它可以通过红外线能量装置、运动装置、卡访问装置、或其它装置来检测空间中的人的存在情况,而占用开关在本发明的上下文中被定义为房间开关, 例如手动操作的灯开关或当占用者进入或离开该空间时由他们操作的其它类型的房间开关。 In the latter sensor or switch rooms, occupancy sensor in the context of the present invention is defined as a sensor: it can be infrared energy means, movement means, the card access device, or other means to detect a person in the space presence while occupying switch is defined in the context of the present invention, the switch for the room, such as a manually operated light switch or when the occupant entering or leaving the room space by other types of their operation switch. 房间开关在本发明的上下文中被定义为其它类型的开关,其例如可以是电气开关、机械开关、光开关、或气动开关,其位于环境中或环境附近,可以被手动地操作为将状态变化传送给与其连接的系统。 In the context of the present invention, the switch room is defined as the other types of switches, which may be for example an electrical switch, a mechanical switch, optical switch, or pneumatic switch, which is located in the environment or the environment, can be manually operated to change the state transferred to the system connected to it. 房间开关可以为了方便共享布线而位于同一房间位置中,并可能地与空气采样拾取装置处于同一包围物(enclosure)中。 To facilitate sharing room switch wiring in the same position in the room, and possibly with the air sampling in the same pickup surround (enclosure) in. 其它类型的房间开关或传感器也可以连接到空气和数据路由器300的I/O块320。 Other types of switches or sensors rooms may also be connected to the air and data routers 300 of I / O block 320.

[0079] 在空气数据路由器300内,多个螺线管阀的输出可以和集气管390A和390B集合在一起。 [0079] in the air data router 300 can output a plurality of solenoid valves together and the manifold 390A and 390B. 这些集气管加上各个螺线管阀(例如空气和数据路由器300C中的361C、或路由器300D中的361D)的输出与管材或空气传输导管202连接在一起,以随着真空源140移动而将空气采样传输到多点空气采样单元200中的共享传感器220。 These manifold coupled with each solenoid valve (e.g., air and data routers 300C in 361C, or 300D of the router 361D) and the output of the air delivery tube or conduit 202 are connected together, with the vacuum source 140 to move the Transfer to a multi-point air sampling air sampling unit 200 shared sensor 220. 通过数据通信电缆201进行空气和数据路由器的控制以及把来自路由器内的I/O块或来自空间中的本地传感器的数字感测的信息和空气质量参数数据传送回到多点空气采样单元200。 201 is controlled by the air and data routers, and the data communications cable from the router's I / O blocks and air quality parameter information or data from the digital space of the sensed local sensors is sent back to the multipoint air sampling unit 200. 可以使用上述用于管材24A的相同材料以及从空间20到路由器300的其他连接来构建空气传输介质202。 Can use the same material for the tubing 20 from the space 24A and the other connected to the router 300.

[0080] 如图1中所示,多点空气采样单元200还连接到因特网170,以将关于环境的信息发送到受口令保护的网站以供占用者或设施人员查看。 [0080] As shown in Figure 1, the multi-point air sampling unit 200 is also connected to the Internet 170, to send information about the environment to a password-protected Web site for viewing occupancy or facility personnel. 同样如图1中所示,多点采样单元200也可以通过数据通信介质181与设施的建筑物控制或管理系统180进行接口连接,并将数据往返发送。 Also shown in Figure 1, multi-sampling unit 200 can also communicate media data 181 and the control facility or building management system 180 to interface, and the data sent back and forth. 可以直接地或通过多个接口协议(例如BacNet、OPC、Echelon的Lon、XML 或其它协议)中的一个来进行该操作。 Either directly or through multiple interface protocols (eg BacNet, OPC, Echelon's Lon, XML or other protocols) in one of the operation.

[0081] 除了空气和数据路由器300之外,建筑物控制系统180也可以用于接受各种传感器输入信号,例如来自本地房间传感器28(:的四(:、以及来自房间开关81的信号82,其中所述空气和数据路由器300可以从空间20接受所感测的输入信号并且提供信号输出31以帮助对房间20进行控制。该信息可以由建筑物控制系统来直接使用用于控制,和/或被传送回多点空气采样系统200。例如,如果房间传感器28C是温度信号,则可以由建筑物控制系统180来检测该信息,并且通过建筑物控制系统或多点空气采样系统来将该信息与从多点空气采样系统的共享传感器220推导出的房间20C的绝对湿度或露点温度信息组合,以创建房间20C的相对湿度或焓测量或信号。建筑物控制系统180还可以使用来自多点空气采样系统100或200的共享传感器信息、以及潜在的本地感测到的信号、房间开关信息、以及其它建筑物信息,从而将由信号31示出的用于帮助控制房间20中的空气流的控制信号提供给房间空气流控制器块30C。 [0081] In addition to the air and data routers 300, a building control system 180 can also be used to accept input signals from various sensors, such as from local room sensor 28 (: tetrakis (:, and the signal switch 81 from the room 82, wherein the air and data routers 300 may sense from the space 20 receives an input signal and providing a detected signal output 31 to assist in the control room 20. This information may consist of a building control system to be used directly to control, and / or sent back to multi-point air sampling system 200. For example, if the room temperature sensor 28C signal, you can by building control system 180 to detect the information, and to the information through the building control system with multi-point air sampling system from absolute humidity or dew point temperature combination of information sharing sensor multi-point air sampling system 220 deduced room 20C to 20C create room relative humidity or enthalpy measurement or signal building control system 180 can also be used from a multi-point air sampling system 20, a control signal 100 or 200 sharing the sensor information, and a signal, switches the room information, as well as other potential local building information sensed thereby shown by the signal 31 is used to help control the flow of air supplied to the room room air flow controller block 30C.

[0082] 图3示出其中一个受监控的区域的更详细的图,所述区域受控于房间空气流控制器和一些空气流控制和反馈设备、以及在其中所使用的信号。 [0082] Figure 3 illustrates one of the areas monitored by the more detailed diagram, in which the signal used for the zone controlled by the room air flow controller and a number of air flow control and feedback equipment, as well. 此外,该图还包括房间回风空气流感测和控制设备41、回风空气流控制信号47、以及房间回风反馈信号48。 In addition, the figure also includes room return air sensing and control device 41, return air flow control signal 47, and the room air return feedback signal 48. 还指示了一个或多个送风空气流感测和控制设备51、送风空气流控制信号57、以及送风空气流反馈信号58。 Also indicates one or more blowing air sensing and control device 51, the blower air flow control signal 57, and the blowing air flow feedback signal 58.

[0083] 虽然指示了回风空气流控制设备,但多数建筑物将仅具有受房间空气流控制器所控制的送风空气流控制设备。 [0083] while indicating return air flow control device, but most of the buildings having an air flow by blowing room air flow control device controlled by the controller only. 在这些情况下,回风是不受控的,并且典型地取道经由顶棚或其它通风空间(plenum space),经由蛋篓型格架(egg crate)或顶棚中的其它网栅,或从房间到通风空间的空气流传输管道或回风管道,从房间或区域回到空气处理单元。 In these cases, the return air is not controlled, and typically by way of the roof or other ventilation space (plenum space), through the egg crate-type lattice (egg crate) or other ceiling grid, or from room to air stream or return air duct ventilation duct space, room or area back from the air handling unit. 回风空气流控制设备通常用于这样的房间:房间和周围房间(例如医院里的隔离室或手术室、或清洁室)之间期望某种压力差或空气流量偏置。 Expect some kind of pressure differential or air flow bias around the room and the room (such as a hospital isolation room or operating room, or clean room) between: return air flow control devices are often used in such a room. 换句话说,在回风流和送风流之间设定偏置空气流,从而基于应用,房间对于周围区域的空气流总是处于稍微负、中性或正。 In other words, between the return air flow and air flow sent Merry setting bias, thus based on the application, the room for air flow in the peripheral region is always slightly negative, neutral or positive. 此外,在某些情况下,如果房间可能包含危险污染物,或由于其它原因,则可能期望将空气流从房间完全排出到外部。 In addition, in some cases, if the room may contain hazardous contaminants, or due to other reasons, it may be desirable to flow air from the room is completely discharged to the outside. 在此情况下,房间回风可以通过管道被送入将房间空气完全排出的排气风机,并且通过由房间空气流控制器30通过控制算法来控制示出为房间回风空气流控制设备的设备,使得该设备有效地成为房间排风空气流控制设备,至少对于这种简单情形,与图5所示的用于房间回风空气流控制设备的控制器相似。 In this case, the room return air can be fed to the room air is completely discharged from the exhaust fan through a pipe, and the room air by the flow controller 30 is controlled by the control algorithm is shown for the room return air flow control device apparatus , such that the device effectively becomes the room exhaust airflow control device, at least for this simple case, shown in Fig. 5 for the controller room return air flow control device similar.

[0084] 如果房间空气流控制器30所控制的房间或区域中不存在回风空气流控制设备, 则图3和相关控制图图5仍可适用,但是房间回风空气流控制设备41及其信号47和48、力口上房间偏置命令32和送风流反馈信号58应该从示出它们的图中被省略。 [0084] If the room or area to the room air flow controller 30 controls in the absence of return air flow control device, Figure 3 and Figure 5 associated control could still be used, but the room return air flow control device 41 and signals 47 and 48, the biasing force of the room on the command port 32 and 58 should send a feedback signal from the air flow which are illustrated in FIG omitted.

[0085] 在图3中,本地温度传感器91通过电缆92与温度控制器90通信。 [0085] In Figure 3, the local temperature sensor 91 via communication cables 92 to a temperature controller 90. 所述温度控制器可以是建筑物控制系统180的一部分、单机系统、房间空气流控制器30的一部分、或以回风或排风空气流控制设备来控制空间或房间中的空气流的分立系统的一部分。 The temperature controller may be a part of the building control system 180, stand-alone system, a portion of the room air flow controller 30, or as return air or exhaust air flow control device to control the space or room in a discrete system air flow part. 这样的后者的控制系统包括图3的房间回风或房间排风和送风空气流控制器设备41和51、以及房间空气流控制器30,并通过维持房间和相邻空间之间的给定房间压力或量偏置来至少控制房间加压,所述控制系统在本发明的上下文中被称为跟踪空气流控制系统,其例如还可以用于风险环境、实验室、医院、饲养室以及各种类型的清洁室。 Such a control system which includes a chart room 3 of the return air and supply air or room exhaust air flow controller device 41 and 51, as well as room air flow controller 30, and by maintaining the space between the adjacent room and to fixed amount of bias to room pressure, or at least the room pressure control, the control system in the context of the present invention is referred to the air flow tracking control system, which for example may also be used for risk environment, laboratories, hospitals, and feeding chamber Various types of cleaning chamber. 在所述后者情况下,房间空气流控制器30在本发明的上下文中还可以被称为跟踪空气流控制器。 In the latter case, the room air flow controller 30 in the context of the present invention may also be referred to track air flow controller.

[0086] 温度控制块90的目的在于提供对房间温度的调节,所述调节可以包含将热负荷或温度命令93发送给房间空气流控制器30,以增大或减少进入空间20的调节送风空气流的量。 [0086] The purpose of the temperature control block 90 is to provide for adjustment of the room temperature, the adjustment may comprise a heat load or temperature command 93 sent to the room air flow controller 30, to increase or decrease the air entering the space 20 is adjusted amount of air flow. 温度控制90还可以控制再热盘管,以增大馈送入空间20的送风空气的温度、或空间20中的作为进一步的温度控制装置的周边(perimeter)加热盘管的温度。 Temperature control 90 may also control the reheat coil, to increase the blowing air is fed into the space 20 of the temperature, or the space 20 as a temperature control apparatus further periphery (perimeter) of the temperature of the heating coil.

[0087] 图5是房间空气流控制器30的控制图的示例性实施例。 [0087] FIG. 5 is an exemplary embodiment of the room air flow controller 30 of the control chart. 由以下信号中较高的一个来设定送风空气流:1)房间温度控制信号,其表示用于维持适当的房间温度的房间送风空气流需求;或2)稀释通风命令信号,其表示基于空间中的污染物水平、的稀释通风的送风空气流需求,在某些情况下加上基于空间二氧化碳水平的测量的为满足空间占用所需的送风空气量。 The higher one of the following signals to set the blower air flow: a) Room temperature control signal, which represents the demand for flow of the room air blower to maintain proper room temperature; or 2) dilution ventilation command signal, which represents dilution ventilation air air flow demand based on the level of contaminants in the space, and in some cases together with the blower to meet the air amount based on the measurement of carbon dioxide levels of space occupied by the space required. 如图5所示,由高选择比较器块34来实现用于这两个信号的最小强制覆盖 5, by the high select comparator block 34 to achieve the minimum of these two signals for mandatory coverage

22(override)或高选择功能,所述高选择比较器块34用于取得向其提供的两个信号中的较高的一个,在任何给定时间,通过该块34的信号总是这两个信号中较高的信号。 22 (override) or high select function, the high select comparator block 34 is used to obtain the two signals supplied thereto in a higher, at any given time, the block 34 via the signal always two higher signal signals. 进入高选择块34的第一输入是用于改变送风流的比例缩放后的温度命令93。 Select the block of the first input into the high 34's is used to change the temperature of the airflow to send commands after scaling 93. 该信号在比例缩放块38中根据需要被比例缩放,并潜在地被偏置,对于模拟电压信号,使其具有与输入到高选择比较器34的其它空气流命令信号相同的比例因子(例如每伏特特定数量的cfm),或者对于表示空气流的软件变量或固件变量,所述温度命令93被直接比例缩放为给定的一组单位(例如每秒cfm或公升)。 This signal is scaled according to the block 38 needs to be scaling, and potentially be biased for analog voltage signal, to have the input to the high select comparator 34 commands other air flow scale factor of the same signal (e.g., per volts specific number cfm), or for showing software or firmware variable variable air flow, the temperature of the command 93 is scaled directly proportional to the given group of units (e.g., cfm or liters per second). 进入块34的第二信号是稀释通风命令信号31,该信号在多点空气采样系统或建筑物控制系统180的辅助下生成,并且同样根据需要由比例缩放块39进行比例缩放和偏置,以使该命令具有与其它信号相同的比例因子。 The second signal into the block 34 is dilution ventilation command signal 31, the signal is generated in the auxiliary multi-point air sampling systems or building control systems under 180, and also in accordance with 39 blocks need to be scaled by the ratio of scaled and biased to so that the command has the same scale factor other signals.

[0088] 进一步示出通过以下方式来创建的用于送风空气流控制设备51的命令57 :取高选择比较器块34的输出,并通过减法块37从该输出中减去偏置信号32。 [0088] further illustrates commands for blowing an air flow control device 51 in the following manner to create the 57: take the output of the high select comparator block 34, and the offset is subtracted from the output signal 32 by subtracting block 37 . 房间偏置空气流命令32可以是固定偏置设定点,例如最大送风或排风cfm的10%,或其可以是来自建筑物控制系统、多点空气采样系统、或跟踪空气流控制系统的信号,其按照两状态、多状态、或VAV 方式改变。 Room air flow command bias 32 may be a fixed bias set point, for example, 10% of the maximum supply or exhaust cfm, or it can be from a building control system, multipoint air sampling systems, or air flow control system to track The signal, which according to the two-state, multi-state, or VAV way to change. 如果使用这种偏置空气流信号或变量32,则该偏置空气流信号或变量32的目的在于创建对采用房间回风或房间排风空气流控制设备的房间来说一般较轻微的负压力、正压力、或中性压力。 If such a bias signal or variable air flow 32, the purpose of the offset signal or variable air flow 32 is to create room for the use of return air or room exhaust air flow control devices are generally more room for slight negative pressure , positive pressure, or neutral pressure. 作为两状态控制信号的房间偏置空气流命令32的一个示例性应用是, 信号32例如是正常房间操作的最大送风量的10%的值。 As a two-state control room air flow command signal bias an exemplary application 32 is the signal 32, for example 10% of the maximum amount of normal room air operation value. 然而,当经由某些传感器、告警系统检测到清洁剂或其他溢出或其它紧急状况(例如着火或烟雾释放)时,或手动地利用房间开关81,可以通过多点空气采样系统100或200、或建筑物控制系统180的控制器中之一来将房间偏置空气流从其正常值增大。 However, when detecting an overflow or other cleaning agents or other emergency condition (e.g., fire or smoke release) via some sensors, alarm systems, or the use of the room manually switch 81, through multi-point air sampling system 100 or 200, or The controller 180 of the building control system to the flow of air from the room normal bias increases. 将偏置空气流增大到潜在的高得多的值例如将降低送风空气流的量,从而对于房间创建大的负偏置空气流,以提供对增多的污染物的测量,从而防止潜在的溢出蒸汽或烟雾扩散进入其它空间。 The air flow is increased to the bias potential value will be much higher, for example, reduce the amount of blowing air flow, thereby creating a large negative bias to the room air flow, in order to provide a measure of the increase of the contaminants, thereby preventing potential Overflow steam or smoke spread into the other space.

[0089] 最后,图5示出如何通过首先以送风流反馈信号58作为开始来创建用于房间回风或房间排风空气流控制设备的命令47的一个实施例。 [0089] Finally, Figure 5 shows how the air flow through the first to send a feedback signal 58 to create a command as start room return air or room exhaust airflow control device 47 for one embodiment. 然后由加法块36将信号58加到房间偏置空气流命令32。 Then by adding block 36 is added to the signal 58 room air flow bias command 32. 所得到的信号是房间回风或排风命令信号47,其用于设定和控制房间回风或排风空气流控制设备41的流。 The resulting signal is room return air or exhaust command signal 47, which is used to set and control room return air or exhaust air flow control device 41 streams.

[0090] 如果受房间空气流控制器30控制的空间或房间没有回风或排风控制设备41,则不存在房间偏置命令32或房间回风命令47。 [0090] If the space or room 30 by the control room air flow controller is no return air or exhaust control device 41, the room or rooms bias command 32 47 return air command does not exist. 此外,送风流命令57简单地等于高选择比较器;34的输出,而不需要减法块37。 Further, send airflow command 57 is simply equal to the high select comparator; output 34, without the need for subtraction block 37.

[0091] 图6示出应用于监控和/或控制目的的空气处理单元的多点空气采样系统的一个优选实施例。 [0091] Figure 6 shows a supervisory control and / or multi-point sampling system of a preferred air control purposes embodiment of the air handling unit. 如图6所示,空气处理单元1000的回风空气1001例如来自房间20或其它区域。 6, the air handling unit return air 1001 20 1000 for example from room or other area. 如所示的那样,回风空气1001来自房间20A的回风管道40A,以及来自通风空间40C, 由来自房间20B的传输管道40B和来自房间20C的顶棚网栅42C对其提供回风空气。 As shown above, return air from room 1001 of the return air duct 20A 40A, as well as from the ventilation space 40C, 42C provide its return air from the ceiling grid 40B and 20B of the transmission pipeline from the room from the room. 20C. 回风空气还可以来自建筑物中的其它位置或区域,如回风管道或通风空间40D所示。 You can also return air from the building to other locations or regions, such as the return air duct or plenum 40D shown. 由空气处理单元1000所提供的送风空气1014通过送风管道50A、50B和50C分别被提供给建筑物中的空间,例如房间20A、20B和20C。 By air supply pipe 50A, 50B, and 50C are provided by the air handling unit 1000 provided an air blower 1014, respectively, to the space in the building, such as rooms 20A, 20B and 20C. 虽然未示出,但也可以由空气处理器单元1000对建筑物的其他区域或房间(例如走廊10)进行送风。 Although not shown, but may be from other areas or rooms of the building air handler unit 1000 (e.g. corridors 10) blows air. 回风风机1002和送风风机1011用于将空气移动通过建筑物。 Return air and supply air blower fan 1002 1011 for air to move through the building. 预过滤器1016典型地用于所示的位置,并且通常是用于外部空气流的粗过滤器。 Pre-filter 1016 is typically used for position shown, and is usually used for a coarse filter outside air stream. 在这之后是典型地更有效和更高等级的过滤器,示出为过滤器1008。 After this is typically more efficient and higher level of the filter, the filter 1008 is shown. 可以通过冷却盘管1012和加热盘管1013来控制送风空气的温度和湿度含量的控制。 Blowing air can be controlled to control the temperature and moisture content of the cooling coil 1012 and through the heating coil 1013. 用于满足各种应用的对于空气处理单元或相似的屋顶单元所使用的过滤器以及加热和冷却盘管的其他组合对于设计空气处理单元的领域的技术人员来说是公知的。 To meet a variety of applications for air handling unit or similar roof unit used filters, and other combinations of heating and cooling coils for the skilled in the art air handling unit design is well known.

[0092] 此外,循环的回风空气1005、排出的回风空气1004、以及外部空气1007的量的控制是通过排气调节风门1003、循环空气调节风门1006、以及外部空气调节风门1067的控制来进行的。 [0092] In addition, circulating return air 1005, discharge of return air 1004, and 1007 of the outside air quantity is controlled by the exhaust damper 1003, recirculation air damper 1006, and an outside air conditioning control damper 1067 to carried out. 这些调节风门也可以是先前对于图1或图2中的诸如设备41A之类所定义的空气流控制设备,尽管图6中的调节风门或空气流控制设备将典型地是由于涉及更大空气量而导致的更大的设备。 The damper may also be previously for FIG. 1 or FIG. 2 or the like, such as devices 41A defined by the air flow control device, although Figure 6 damper or air flow control device will typically be due to the greater amount of air involved result of larger equipment. 图6将用于控制这些调节风门的控制信号示出为外部空气调节风门控制信号1068、排气空气调节风门控制信号1070、以及循环空气调节风门控制信号1072。 Figure 6 a control signal for controlling the damper is shown as an external air adjusting damper control signal 1068, an exhaust air damper control signal 1070, and the recirculation air damper control signal 1072. 本领域技术人员知晓多种方法和算法来控制这些调节风门的相对位置。 The skilled person knows a variety of methods and algorithms to control the relative position of the damper. 典型地,建筑物控制系统180或空气处理控制单元1015将控制这些调节风门,以满足建筑物的各种需求,例如关于所需的外部空气量、与建筑物的加热和制冷有关的能量效率的问题、以及建筑物加压。 Typically, the building control system 180 or air processing control unit 1015 to control the damper to meet the various needs of the building, for example, with regard to the required amount of outside air, and the building's heating and cooling energy efficiency-related problems, and the building pressure.

[0093] 在现有技术系统的情况下,尤其是关于所需外部空气的量的控制,已经能够监控空气处理单元1000的操作,和/或有帮助对其进行更精确、可靠、和更加成本高效地进行控制,可以通过使用多点空气采样系统(例如图6中示出为块1000的多点空气采样系统)来监控若干空气处理器位置。 Operation [0093] In the case of the prior art systems, particularly with regard to the control of the amount of external air required, has been able to monitor the air handling unit 1000, and / or help them more accurate, reliable, and more cost- efficiently controlled by using the multi-point air sampling system (e.g., FIG. 6 shows a block 1000 for a multi-point air sampling system) to monitor the position of a plurality of air processor. 为了例示的目的,在图6中,多点空气采样系统1000被示出为星形配置的多点空气采样系统,与图1中的多点空气采样系统100的配置相似。 For purposes of illustration, in Figure 6, multi-point air sampling system 1000 is shown as a star configured multipoint air sampling system, similar to the configuration in Figure 1 multipoint air sampling system 100. 然而,本发明同样可适用于网络化的空气采样系统,例如图2的块200和300所示出的。 However, the present invention is equally applicable to networked air sampling system, such as illustrated in FIG. 2 blocks 200 and 300. 相似地,本发明可以用于网络化光子采样系统。 Similarly, the present invention can be used for networked photonic sampling system.

[0094] 为了监控空气处理器的操作的多数方面,并更好地控制它,图6所示的其中一个优选感测位置涉及在回流风机之前或之后感测回风1002,并且具有空气采样位置1031和本地管道传感器1021,所述本地管道传感器1021对于大多数应用来说典型地是温度传感器。 [0094] In order to monitor most aspects of the operation of the air handler, and better control of it, as shown in FIG. 6 wherein a preferred position sensing relates reflux fan before or after sensing the return air 1002, and having an air sampling position 1031 and local duct sensor 1021, the local duct sensor 1021 for most applications is typically a temperature sensor. 另一优选感测位置涉及典型地在风机以及各种加热和制冷盘管之后感测送风,以更好地确保送风管道内的温度和空气污染物的更均勻的分布。 Another preferred position sensing involves typically after the fan and various heating and cooling coils sensed air, to better ensure that the temperature and air pollutants within the air duct more uniform distribution.

[0095] 图6示出该情况,具有采样位置1037和本地管道传感器1027,所述本地管传感器1027典型地是温度传感器。 [0095] Figure 6 shows the case, having a sampling location 1037 and local duct sensor 1027, the local tube sensor 1027 is typically a temperature sensor. 前述感测位置涉及感测外部空气。 Sensing the position of the foregoing involve sensing the outside air. 在图1和图2中,以采样位置63和本地管道传感器65来执行该操作。 In Figures 1 and 2, the sampling position sensor 63 and the local pipeline 65 to perform the operation. 在图6中,在外部空气调节风门1067和预过滤器1016之前,例如在外部空气管道中由空气采样位置1023和本地管道传感器1033感测外部空气1007,所述本地管道传感器1033典型地是温度传感器。 In Figure 6, before the outside air damper 1016 and 1067 pre-filter, for example, by the outside air duct air sampling location 1023 and local duct sensors 1033 sense the outside air detected 1007, the local duct sensor 1033 is typically a temperature sensor. 最后,还可能有助于感测的位置在空气处理器的混合空气通风间(plenum)中,其中,存在空气处理器的混合空气1009。 Finally, also may contribute to the sensed position in the mixed air ventilation between the air handler (plenum) in which the presence of the mixed air 1009 of the air handler. 这种空气与送风空气相似,但尚未被空气处理器过滤、加热或冷却,所以它更接近地反映了回风空气1005和外部空气1007的混合空气质量参数特性。 Such air and blowing air are similar, but has not yet been filtered air handlers, heating or cooling, so that it more closely reflects the return air and outside air 1005 1007 air quality parameter characteristics. 由空气采样位置1035和本地管道传感器1025来感测混合空气1009,所述本地管道传感器1025对于大多数应用典型地是温度传感器。 By air sampling location 1035 and 1025 local pipe sensor to sense the mixed air 1009, the local pipe sensor 1025 for most applications typically is a temperature sensor. 注意必须小心地选择混合空气通风间中的空气采样和管道传感器位置是有用的。 Note that you must be careful to choose between the mixed air ventilation and air sampling pipe sensor location is useful. 在很多空气处理器中,在过滤器1008之前的混合空气通风间中可能较差地混合了回风和外部空气,这产生由于出现在回风和外部空气中的不同的值而导致的非均勻空气污染物和温度分布。 In many air handler, in 1008 prior to the mixing between the air plenum filter may be poorly mixed return air and outside air, which results in non-uniform due to the return air and outside air caused by different values air pollutants and temperature distribution.

[0096] 关于所感测的管道位置,当多点空气采样系统用于对管道系统、通风间、空气处理器进行采样,或者在部分密闭的区域(例如管或管道)中的流动的空气要以远程传感器来采样和测量的任何其它应用中,可以将管子或空心管道探针插入管道或部分密闭的空间中,以取出采样,或可以在管道中制成孔,并从连接到管墙中的开孔的管子从管道提取采样。 [0096] With regard to the sensed position of the pipe, when the multi-point air sampling system for piping systems, airy, air sampling processor, or in a part of the closed area (e.g., tubes or pipes) in flowing air should Remote sensors to sample and measure any other applications, can be a hollow tube or probe is inserted into the pipe or pipe section closed space in order to remove the sample, or may be made in the pipe hole, and is connected to the tube wall from the samples extracted from the pipe conduit opening. 然而此外,如上所述,还需要一个或多个分立的温度或其它参数或污染物感测探针来搞清楚从这些管道或部分密闭的区域中期望怎样的本地传感器测量。 In addition, however, as described above, also need one or more discrete temperatures or other parameters or contaminants sensing probe to find out how these pipes from or partially enclosed area in a desired local sensor. 可以在这些位置上采用用于感测流动的空气流、并且用于抽取空气采样的多个分立的探针,或者可以使用唯一的集成采样探针,其使用用于本地空气特性测量并且用于空气采样的一个探针,如题为“DUCT PROBE ASSEMBLY SYSTEM FORMULTIPOINT AIR SAMPING” 的美国专利申请第11/312,164 号中所描述的,通过引用将该专利申请并入本文中。 May be used for sensing air flow flowing in these positions, and for extracting a plurality of air sampling probe discrete, or may use only integrated sampling probe, which is used for local use and for measuring the characteristics of air US patent application a probe air sampling, as entitled "DUCT PROBE ASSEMBLY SYSTEM FORMULTIPOINT AIR SAMPING" in No. 11 / 312,164 described by the patent application is incorporated by reference herein. 这种类型的集成管道探针或其它非集成管道探针可以用于感测图1、图2、或图3中所涉及到的任何管道位置。 This type of integration of the probe or other non-integrated piping duct probes can be used to sense the Figure 1, Figure 2, Figure 3, or any position in the pipeline involved. 此外,本发明还涉及使用空气采样管道探针,所述探针使用沿着管道的截面扩散的多个感测孔,以获得管道状况的较好的平均值。 Further, the present invention also relates to the use of an air sampling pipe probe, the sensing probe using a plurality of apertures along the cross-section of the pipe diffusion, in order to obtain a better average of the pipe condition. 这种类型的多拾取采样探针加上在后者的专利申请中描述的平均管道温度传感器可以被有利地用于例如测量空气处理器的混合空气1009。 This type of multi-pickup sampling probe plus the average pipe temperature sensor in the latter patent application described herein may be advantageously used, for example measuring the mixed air 1009 of the air handler.

[0097] 如图6所示,多点空气采样系统1100接受四个前述的空气采样位置,它们由空气采样管子1032、1034、1036和1038从采样位置1031、1033、1035和1037分别连接到螺线管阀1163、1164、1162和1161。 [0097] As shown, the multi-point air sampling system 6 1100 to accept the position of the four aforementioned air sampling, air sampling tubes are made 1032,1034,1036 and 1038 connections from the sampling location 1031,1033,1035 and 1037 respectively to screw Line pipe valve 1163,1164,1162 and 1161. 这种管材与前面参照图1和图2所描述的管材24A相似。 This pipe above with reference to Figures 1 and 2 described in the pipe 24A is similar. 这些空气处理器位置处的空气质量参数被共享传感器1120所感测,并被信号处理控制器1130处理,所述信号处理控制器1130可以实现图4中对于信号处理控制器530所示的全部功能。 Air quality parameters at the location of the air handler is shared by the detecting sensor 1120 is detected, the processing by the signal processing controller 1130, the signal processing controller 1130 may implement all of the functions shown in Figure 4 with respect to the signal processing controller 530. 螺线管161到164也受控制逻辑块1110控制。 Solenoid 161 to 164 are also controlled by the control logic block 1110. 最后,多点空气采样系统1100可以通过传感器输入块1150接受本地房间或管道传感器信号或信息。 Finally, multi-point air sampling system 1100 can accept local room or duct sensor signals or messages through the sensor input block 1150. 这个块分别通过电缆1032、1034、1036和1038感测本地管道传感器1031、1033、1035和1037。 This block through cable 1032,1034,1036 and 1038 respectively sensing local pipe sensor 1031,1033,1035 and 1037. 这些电缆与前文中对于图1和图2描述的电缆26A相似。 These cables are similar to that previously described in respect to two cable 26A described in FIG. 1 and FIG. 作为替换方案,本地管道传感器1031、1033、1035、 或1037可以通过无线或无线网络装置(例如无线网状网络(mesh network))将它们的空气质量参数信息传递给传感器输入块1150。 As an alternative, the local pipeline sensors 1031,1033,1035, or 1037 may be a wireless or a wireless network device (e.g., a wireless mesh network (mesh network)) passing them on air quality parameter information to the sensor input block 1150.

[0098] 所图所示可以将信号处理控制器1130的控制或监控信号输出提供给例如建筑物控制系统180,以控制外部空气调节风门1067,或提供给其它建筑物系统或控制器,例如空气处理器控制块1015,或更具体地说,提供给外部空气流控制器块1200,其可以用于生成外部空气流命令信号1075,并且通过图9中对其进行更详细的描述。 [0098] The signal processing controller shown in FIG control or supervisory signal output 1130 may be provided to control system 180 such as a building, in order to control the outside air damper 1067, or provided to other building systems or controllers, such as air processor control block 1015, or more specifically, to an external air flow controller block 1200, which may be used to generate an external air flow command signal 1075, and be described in greater detail by FIG. 9. 虽然图6中未示出,但建筑物控制系统180、空气处理器控制块1015、或其他控制器可以用于在来自外部空气流控制器1200的外部空气流命令信号1075的帮助下,通过使用外部空气调节风门1067额外加上其他空气处理器调节风门1003和1005,来控制进入建筑物的外部空气流。 Although not shown in Figure 6, but the building control system 180, air handler control block 1015, or other controller can be used in the outer air flow command signal from the external controller 1200 with the help of air flow 1075, through the use of additional outside air damper 1067, together with other air handler damper 1003 and 1005, to control the flow of outside air entering the building.

[0099] 此外,图1、图2和图6中提及的控制或感测方法、或控制输入或输出可以应用于其它附图的系统或方法。 [0099] In addition, FIG. 1, the control or sensing method in Figures 2 and 6 mentioned, or the control input or output may be applied to other systems or methods of the drawings. 相似地,这些相同的方法或系统可以应用于与图1、图2或图6相似的设施监控系统实施例,它们不是以多点空气采样系统来实现,而是使用光纤光分组采样和感测系统来实现,例如美国专利第6,252,689号所描述,并且在本专利中被称为网络化的光子采样系统。 Similarly, the same method or system can be used with the FIG. 1, 6 similar facility monitoring system embodiment of FIG. 2 or FIG., They are not to multipoint air sampling system to achieve, but the use of fiber optical packet sampling and sensing system to achieve, for example, U.S. Patent No. 6,252,689 described, and is referred to in this patent networked photonic sampling system.

[0100] 涉及使用多点空气或光子采样系统的混合空气质量参数信号的创建开始于虚拟空气质量参数信号的创建,通过对图1、图2、图4、或图6的共享传感器块120、220、520、或1120的传感器流信号解复用来创建所述虚拟空气质量参数信号,分别由图1、图2、图4、或图6中的信号处理控制器块130、210、530、或1100来执行所述解复用操作。 [0100] involving the use of creating a virtual air quality parameter starts at a signal created multipoint air sampling system or photon mixing air quality parameter signal, by Figure 1, the shared Figs. 2, 4, or 6 of a sensor block 120, 220,520, or 1120 Solutions sensor flow signal multiplexing is used to create the virtual air quality parameter signals, respectively, by Figs. 1, 2, 4, or FIG. 6 the signal processing controller block 130,210,530, or 1100 to perform the demultiplexing operation. 在图4的信号处理控制器块530中示出进行所述解复用加上其它功能的信号处理控制器块的信号处理逻辑的一部分的实现。 In Figure 4 the signal processing controller block 530 of Fig. 23 shows the demultiplexing plus implemented as part of the signal processing controller block of signal processing logic of the other functions. 在此图中,所述控制功能可以按照模拟或数字逻辑实现,或者通过计算机软件或固件程序或它们的任何组合来实现。 In this figure, the control function may be implemented in accordance with the analog or digital logic, or computer software or firmware programs, or any combination thereof to achieve. 在图4中,共享传感器520创建一个或多个输出信号或变量,其被示出在附图中例如作为传感器信号525、5沈和527,这些信号分别表示各个传感器C02、湿度(例如被测量为露点温度、绝对湿度、或水蒸气浓度)、以及TVOC 的输出。 In Figure 4, the sensor 520 to create a shared or more output signals or variables, which is shown in the drawings, for example, as a sensor signal 525,5 Shen and 527, these signals represent the respective sensor C02, humidity (e.g., measured dew point temperature, absolute humidity, or water vapor concentration), and TVOC output. 虽然图4示出使用这三个传感器,但可以使用任意数量或类型的传感器。 Although Figure 4 shows the use of three sensors, but can use any number or type of sensor. 由于已经从多个房间(在该示例中是三个房间)使传感器对于空气采样进行复用,因此如上所述,给定空气质量参数的与传感器信号对应的给定房间的各个或“虚拟”传感器信号、或者该房间或区域中的所表示的软件变量必须从空气质量参数的信号流中被解复用。 As has been from a plurality of rooms (in this example are three rooms) for air sampling sensor are multiplexed, and therefore as described above, a given air quality parameter sensor signal corresponding to each of a given room or "virtual" sensor signals, or the room or area in software variable represented must be demultiplexed from the signal stream of air quality parameter. 由解复用器531、 532和533在信号处理控制器530内进行该操作,所述解复用器531、532和533使用来自控制逻辑块510的控制信号511来分别对C02、湿度、以及TVOC传感器信号进行解复用。 By the demultiplexer 531, 532 and 533 to carry out the operation in the signal processing controller 530, the demultiplexer 531, 532 and 533 using a control signal from the control logic block 510 to 511 respectively C02, humidity, and TVOC sensor signal demultiplexing. 块510分别与图1和图6的控制逻辑块110和1100、以及图2中的信号处理控制器块210的一部分和控制逻辑块310A、310B和310C的一部分相对应。 Part of the control logic block 510 and block 110 1100, and in Figure 2 a portion of the signal processing controller block and the control logic block 310A 210, 310B and 310C, respectively, in Fig. 1 and Fig. 6 corresponds. 解复用器块531、532和533的输出是各个或“虚拟”传感器信号或软件变量,其表示房间20A、20B和20C的所感测的空气质量参数。 Output demultiplexer block 531, 532 and 533 are each or "virtual" sensor signal or software variable which represents the room 20A, 20B, and air quality parameters sensed. 20C. 例如,信号522A、522B和522C分别表示房间20A、20B和20C中的所感测的C02 水平的信号或变量。 For example, signals 522A, 522B and 522C respectively denote room 20A, C02 levels 20B and 20C in the sensed signal or variable.

[0101] 这些虚拟传感器信号将典型地具有表示最后解复用的值的值,所述最后解复用的值将在该水平保持恒定,直到对该信号的相应位置的下一采样,将基于应用的需要每几分钟或更有可能每10至30分钟进行所述采样。 [0101] The virtual sensor signal will typically have a final demultiplexed represents the value of use, solutions of the final value of multiplexing will remain constant at this level until the signal corresponding to the position of the next sample, based on need to be applied or are more likely to be the sampling every few minutes every 10 to 30 minutes. 此时,信号将把值改变为等于新的解复用后的值。 In this case, the signal will be changed to the value equal to the new value of the demultiplexed. 这种从一个解复用后的值到下一个解复用后的值的状态的转变可以作为快速变化而发生,或近似地作为信号的阶跃变化而发生,或者它可以按照斜坡方式逐渐出现,所述斜坡方式取决于虚拟信号的期望的特性、信号可能正在控制什么、以及对位置进行采样的频率, 而在时间上持续几秒钟到很多分钟。 This demultiplexed from a value to the next transition of a demultiplexed values after a state change occurs as quickly, or approximately as a step change in the signal occurs, or it can occur gradually ramp way in accordance with , the slope depends on the desired characteristics of the virtual signal, the control signal may be any, as well as the position sampling frequency, and in the time for a few seconds to many minutes. 用于控制应用的信号的一种优选方法将具有在5秒到60秒中发生值的逐渐改变。 A preferred method for controlling the application of a signal having a gradual change in the value of 5 seconds to 60 seconds.

[0102] 如果我们再次关注房间20A的变量,则用于C02、湿度和TVOC的信号分别是522A、 523A和524A。 [0102] If we are concerned about the room again 20A of variables, for C02, humidity and TVOC signals are 522A, 523A and 524A. 如上所述,其后可以根据需要利用偏置和比例缩放因子块534A、535A、和536A 分别来修改这些各个或虚拟传感器信号522A、523A和524A,或者其后可以应用一些其它控制功能。 As mentioned above, the subsequent use as needed bias and scaling factor block 534A, 535A, and 536A, respectively, or to modify each of these virtual sensor signals 522A, 523A and 524A, or later can use some other control functions. 此外,传感器输入块550的输入可以是本地房间或管道传感器,例如其在图1和图2中被示出为例如25A、27A和27B。 Furthermore, the sensor input 550 of the input block can be a local room or duct sensors, for example which is shown, for example, 25A, 27A and 27B in Figures 1 and 2. 来自这些传感器^A、28A和^B的信号被应用于传感器输入块阳0,所述传感器输入块550可以对这些信号进行缓冲,并且其后将这些信号提供给信号处理控制器530。 From these sensors ^ A, 28A and ^ B signal is applied to the sensor input block male 0, the sensor inputs block 550 may buffer these signals, and thereafter these signals to the signal processing controller 530. 具体地说,对于房间20A,信号551A表示来自本地温度传感器25A 的信号,并且信号552A表示来自本地房间传感器27A的信号。 Specifically, for the room 20A, 551A signal represents the signal from the local temperature sensor 25A, and the signal 552A represents the signal from the sensor 27A of the local room. 通过虚拟信号,本地传感器信号551A和552A其后可以根据需要而被偏置和比例缩放因子块561A和562A分别修改, 或者除了偏置和比例因子缩放功能之外(还)通过一些其它功能来修改,其中所述偏移和比例缩放功能典型地提供Y = AX+B的功能,其中,Y是输出,X是输入。 Through virtual signal 551A and 552A local sensor signal can then be biased to the needs and the scaling factor block 561A and 562A, respectively, modify, or in addition to bias and scale factor other than the zoom function (also) be modified by a number of other functions , wherein the offset and the scaling function is typically provided function Y = AX + B, where, Y is the output, X is the input. 其后由多输入功能块537A对来自块534A、535A、536A、56IA和562A的修改后的信号进行作用,在本示例中,所述多输入功能块537A通常涉及与房间20A关联的信号。 Followed by a number of function block input from the block 537A to 534A, 535A, 536A, and 562A of the signal modification 56IA performed after effect, in the present example, the multiple input function block 537A generally relates to a signal associated with the room 20A. 作为替换方案,也可以由例如用于创建其中一些空气质量参数信号的差分信号形式的多输入功能块537A来使用来自其它区 As an alternative, you can create a differential signal which is used for example in the form of a number of air quality parameters of the signal of the multi-input function blocks 537A to use from other zones

26域或管道位置的空气质量参数信号。 Air quality parameter signal domain or conduit 26 position. 此外,虽然图4中未示出,但信号处理控制器可以包含多输入功能块,以硬件、或以固件、软件或其组合来实现这些多输入功能块,以创建其它空间或房间的各种混合空气质量参数信号。 In addition, although not shown in FIG. 4, but the signal processing controller may comprise a multi-input function block, in hardware, or firmware, software, or combinations of these multi-input function block, in order to create additional space or room of the various mixed air quality parameter signals. 来自多输入功能块537A的输出信号(例如稀释通风反馈信号538A)可以进一步由输出控制块MOA来处理或修改,以便例如生成输出命令信号,例如稀释通风命令信号31。 Multiple input function block 537A of the output signal from the (e.g., dilution ventilation feedback signal 538A) may be further controlled by the output block MOA to be processed or modified, for example, to generate an output command signal, such as dilution ventilation command signal 31. 例如,如图8所示的控制环路功能、或者图7所示的具有或不具有滞后的阈值水平比较器可以用于输出控制块Μ0Α,而不是功能块537A,以将由多输入功能块537A所产生的混合空气质量参数反馈信号转换为命令信号输出,所述命令信号输出可以用于控制稀释通风的最小送风空气流水平,或用于其它目的。 For example, the control loop functions shown in Figure 8, or as shown in FIG. 7 with or without a hysteresis threshold level of the comparator output can be used to control block Μ0Α, instead of the function block 537A, in order to by multiple input function block 537A mixed air quality parameters generated by the feedback signal into the output of the command signal, the command signal output can be used to control the minimum air dilution ventilation airflow level, or for other purposes.

[0103] 如图4所示,多输入功能块537A还可以具有多个输出,其中,示出第二输出571A, 它是用于相对湿度的混合监控或反馈控制信号。 [0103] As shown in Figure 4, multiple input function block 537A may also have a plurality of outputs, wherein is shown a second output 571A, which is used to monitor the relative humidity of the mixing or feedback control signal. 可以使用公知的干湿计(psychrometric) 将绝对湿度或露点输出532A与本地温度传感器输出551A组合,以创建相对湿度信号571A, 或者如果期望,创建其它与含水量有关的信号,例如湿球温度或焓。 You can use the well-known psychrometer (psychrometric) the absolute humidity or dew point output 532A and 551A local temperature sensor output combined to create a relative humidity signal 571A, or, if desired, to create additional moisture associated with the signal, such as wet bulb temperature or enthalpy. 这种混合相对湿度信号571A可以用于监控或作为反馈信号,所述反馈信号可以由另一控制器使用,以便控制空间20A中的相对湿度水平,或由与MOA相似的另一输出控制块使用,以便创建相对湿度命令信号,所有信号都来自信号处理控制器530内。 This mixed signal 571A relative humidity can be used to monitor or as a feedback signal, the feedback signal may be used by another controller, to control the relative humidity level in the space 20A, or by other output with MOA similar control block used to create a relative humidity command signal, all signals from the signal processing controller 530.

[0104] 更详细地描述多输入功能块537A,该块例如可以将信号输入相加在一起;获取不同信号之间的差,从而创建微分信号;高选择或取各种信号中较高的那个;低选择或强制覆盖各种信号;将阈值或信号模式触发功能单独地、作为群组、或作为子群组而施加于信号,以修改信号或创建新的信号;应用与图8所示的输出控制块MOA相似的控制环路功能; 应用图7所示的滞后功能;应用任何布尔逻辑、线性、或非线性功能;或者应用任何其它有利的功能或方法来混合或使用这些信号,以创建混合监控信号或控制信号。 [0104] more detailed description of multi-input function block 537A, for example, signal inputs can be added together in the block; obtaining the difference between the different signals, thereby create a differential signal; a high selectivity or to take the higher of the various signals ; low selectivity or forced to cover various signals; the threshold or signal pattern trigger function individually, as a group, or as a subgroup is applied to the signal, a signal to modify or create a new signal; Application and shown in Fig. 8 output control block MOA similar control loop functions; hysteresis function application shown in Figure 7; applying any Boolean logic, linear or non-linear function; or apply any other beneficial functions or methods to mix or use these signals to create Mixed monitor signal or a control signal. 块537A的结果在于创建以下信号中的一个或多个:可以用作稀释通风反馈的基础的两状态、三状态、或多状态、或连续可变混合空气质量参数信号、稀释通风命令,外部空气命令、以及其它监控信号或控制反馈信号。 Result block 537A is to create the following signal one or more of: a two-state can be used as the basis of dilution ventilation feedback, three-state, multi-state, or a continuously variable mixing of the air quality parameter signal, dilution ventilation command, the outside air commands, and other monitoring or control signals the feedback signal. 最终,该命令或反馈信号或控制变量其后可以输出到建筑物控制系统或输出到另一系统,作为数字信号或变量(例如稀释通风反馈信号538A),或者作为空气流命令信号或软件变量(例如由输出控制块^OA所创建的稀释通风空气流命令信号31A),并用作到房间20A的环境空气流控制块30A的输入。 Ultimately, the command or feedback signals can be output or control variable subsequently to a building control system or to another system outputs, as a digital signal or variable (e.g., dilution ventilation feedback signal 538A), or as an air flow command signal or software variable ( such as dilution ventilation air flow by the output control block ^ OA created command signal 31A), and 20A is used as the room ambient air flow control block 30A of the input.

[0105] 可以在多输入功能块537A内或潜在地在输出控制块MOA中实现的另一功能是时间延迟或斜坡功能,当创建用于控制系统的不连续输出信号(例如两状态、三状态、或多状态信号)时,所述时间延迟或斜坡功能非常适用。 [0105] can be in multiple-input function block 537A or potentially another function in the output control block MOA implemented is the time delay or ramp function, when used to create discrete output signal control system (such as two-state, three-state or multi-state signal), the time delay or slope is very applicable. 由于很多控制系统不能以稳定方式来响应快速变化的信号,因此它在某些情况下是有用的,用于从多状态信号有效地创建连续可变信号。 Since many control systems do not respond in a stable manner to rapid changes in the signal, and therefore it is useful in certain circumstances, be used to create a continuously variable signal from a multi-state signal effectively. 例如,当超过了用于给定空气质量参数信号或混合空气质量参数的阈值时,功能块537A或MOA的输出可以被增大到其最大值或净化(purge)值,其例如可以对应于5ACH 至15ACH之间的房间换气水平。 For example, when it exceeds a threshold air quality parameter or blended air quality parameter signal for a given output function block 537A or MOA may be increased to its maximum or purification (purge) value, which for example may correspond to 5ACH room ventilation levels to 15ACH between. 这种值的增大可以即刻出现,或者也可以由功能块537A或MOA命令为逐渐以斜坡倾斜。 This increase in value can occur immediately, or it may be a gradual ramp incline by the function block 537A or MOA command. 这样的斜坡倾斜或缓慢增大的信号可以发生一分钟或更长的时间段。 Such inclination or slope of the signal can occur slowly increasing or longer time period one minute. 该操作还可以有助于防止控制系统或空气流控制设备不成功地试图跟上快速变化的信号所产生的问题,如果送风和回风空气流控制设备没有恰当地跟踪变化的空气流命令信号,则在具有回风或排风空气流控制设备的空间例如在房间20A中的情况下,会导致加压问题。 The operating system can also help to prevent or control air flow control device unsuccessfully attempted to keep pace with rapidly changing signal problem generated, if the supply and return air flow control device is not properly track changes in air flow command signal , then the return air or exhaust air having a flow control device 20A in the room space, for example under the circumstances, can lead to pressure problems. 相似地,当稀释通风命令信号表示要从较高水平(例如10ACH)降低到较低水平或最小水平(例如2ACH)时,功能块537A可以创建缓慢斜坡,其在某个时间段(例如一分钟或更长)中逐渐降低输出信号31A。 Similarly, when the dilution ventilation command signal indicates to a lower level or a minimum level (e.g. 2ACH) from a higher level (e.g. 10ACH), function blocks 537A to create a slow ramp, which in a certain time period (e.g., one minute or longer) gradually decreases the output signal 31A.

[0106] 相似地,水平的这种增大或降低斜坡或逐渐改变可以是具有恒定增大或降低速率的线性方式,或者也可以是例如具有指数变化速率的非线性方式,因此斜坡可以更快地开始并逐渐放慢或反之缓慢地开始并逐渐增大其值的变化速率,直到信号达到最终的值。 [0106] Similarly, the level of such increase or decrease may be a gradual change or ramp having a constant rate of increase or decrease in a linear manner, or may be for example, a non-linear manner exponential rate of change, and therefore faster ramp and gradually began to slow down or vice versa and slowly began to gradually increase the rate of change of its value, until the signal reaches the final value. 这些斜坡还可以基于信号是增大还是减小而处于不同速率。 The ramp may also be based on the signal is increasing or decreasing and at different rates. 例如,可能有利的是,如果检测到房间中的空气质量参数水平显著增大,则通过快速增大稀释通风命令31来快速增大房间的通风。 For example, it may be advantageous if it detects the room air quality parameter levels were significantly increased, by rapidly increasing the dilution ventilation command 31 to quickly increase the room is ventilated. 例如,可能已经由于清洁剂而发生溢出。 For example, the cleaning agent may have been due to overflow. 然而,具有缓慢向下的斜坡也可能是有帮助的;可能用5分钟到15分钟来逐渐降低稀释通风流,以确保空气质量参数甚至被移除到低于检测阈值的水平。 However, having a slow downward slope may also be helpful; may 5 to 15 minutes to gradually reduce the dilution ventilation flow, in order to ensure that the air quality parameter or is removed to a level below the detection threshold.

[0107] 在大信号范围中对变化的流进行斜坡变化的一个替换方案中,出于与上述相同的原因,可能期望不仅改变由块537A或MOA的例如对于稀释通风命令信号31的输出的变化速率,而且还基于例如来自共享的解复用后的传感器信号522A、523A、和/或524A的所感测的空气质量参数的变化来改变可能的阶跃变化量。 [0107] In the large-signal range of variation of the flow of a change in slope in the alternative, for the same reason as described above, it may be desirable to change not only by changes in the block 537A or MOA such as dilution ventilation command for the output signal 31 rate, but also on e.g. sensor signals 522A Solutions from shared multiplexed, 523A, and changes in air quality parameters and / or 524A of the sensed amount of change may be changed step. 换句话说,与从一个空气采样测量允许从最小稀释等级到最大稀释等级的完全转换(full slew)相比,可能更加期望限制稀释通风空气流中的最大阶跃变化,或者对块537A或MOA的信号输出的等级能够多快地变化施加转换等级(slew rate)极限。 In other words, compared with from one air sampling measurements allow complete conversion (full slew) was diluted from minimum level to maximum level of dilution, the dilution may be more desirable to limit the maximum ventilation air flow step changes, or to block 537A or MOA The signal output level can change how fast switching levels applied (slew rate) limit. 限制输出信号的阶跃大小或转换等级的优点在于,对于信号幅度的一般变化,这种方法产生非常少的延迟,导致更加稳定的控制。 Limiting the output signal of the advantages of the conversion step size or level is that, for the average change in signal amplitude, this method produces very little delay, resulting in more stable control. 作为这种方法的一个示例,可以将最大阶跃变化大小设定成表示在从最小的2ACH到最大的8ACH的可能范围中的2ACH的空气流的增大。 As one example of this method, can be set to represent the maximum step change increases in size from the smallest to the largest possible range 2ACH 8ACH 2ACH in air flow. 例如在将最大阶跃大小设定为2ACH的情况下,可以取三个连续的空气采样,其具有超过触发值的空气质量参数值,以便将稀释通风命令信号31从最小值提升到其最大值。 For example, the step size is set to the maximum case 2ACH can take three successive air sampling, having an air quality parameter value exceeds the trigger value, in order to enhance the dilution ventilation command signal 31 from the minimum value to its maximum . 相似地,如果最大降低也被限制为等于2ACH的流等级,则将取低于用于稀释命令水平的触发值的环境空气质量参数的三个连续测量,从对应于8ACH的水平降低到2ACH。 Similarly, if the maximum reduction is also restricted to equal 2ACH stream level, it will take less than three for dilution ambient air quality parameter level trigger command value of the continuous measurement, from a level corresponding to 8ACH reduced to 2ACH.

[0108] 按照与上述斜坡方法相似的方式,阶跃高度的增大或降低可以具有不同的大小。 [0108] Following a similar manner to the method described above the ramp, the step height of the increase or decrease may be of different sizes. 例如,为了快速响应于清洁剂的溢出,对于稀释通风命令31的向上或增大变化,可以没有极限或具有较大的极限。 For example, in order to respond quickly to the overflow of the cleaner for the dilution ventilation command 31 is increased upward or changes, there is no limit or may have a larger limit. 然而,如果源不是溢出而是连续发射,为了确保使大量稀释降为很低的水平并且降低振荡的概率,可能有利的是,具有较小的阶跃变化大小的降低,以将稀释通风保持在较高水平达到较长时间段,从而花费几个空气采样周期来将通风水平充分降低到其最小值。 However, if the source is not overflow but the continuous emission, in order to ensure that a large number of diluted reduced to very low levels and reduce the probability of oscillation, it may be advantageous, with smaller changes in the size reduction step, in order to keep the dilution ventilation a longer period of time to reach a higher level, so it takes a few cycles to the ventilation air sampling sufficiently reduced to its minimum level.

[0109] 用于设定阶跃高度或也可能是斜坡坡度的另一手段基于所检测的空气质量参数或其变化率的水平。 [0109] is used to set the step height, or it may be another means the gradient of slope of the level of air quality parameters, or based on the rate of change detected. 如果自从最后的采样或最近的几个采样以来检测到空气质量参数的较大值和/或其水平的快速上升,则可能有利的是,使用不同的阶跃变化高度或斜坡坡度。 If the sample since the last or most recent large value of several sampling detected air quality parameter and / or a rapid rise in the level, it may be advantageous to use a different step changes in height or slope gradient. 例如,在其中突然增大到大的空气质量参数值的溢出中,立即将稀释通风命令信号31标记为其最大值可能是比较谨慎的。 For example, where a sudden increase to large overflow air quality parameter values, immediately dilution ventilation command signal 31 to its maximum value tag may be more cautious. 当感测的空气质量参数以比较小的阶跃或者更加逐渐的改变来移动时,可以使用值的较小的或更逐渐的增大。 When the sensed air quality parameter with a relatively small step or a more gradual change to move, or can use the value increases more gradually smaller. 另一方面,所感测的空气质量参数或混合信号的急速的向下改变可能不改变向下阶跃水平,以保持较高的通风更长时间,来更好地清洁空气。 On the other hand, the rapid downward change sensed air quality parameter or the mixed signal may not alter the step-down level, in order to maintain a high ventilation longer, to better clean air. 作为替换方案,出于节能的原因,和/或如果偶然有很多空气质量参数的短暂向上漂移,其可能并不危险,如果空气质量参数水平已经刚刚快速下降到触发水平之下,则将稀释通风命令信号31快速降低到其最低水平可能更有利。 As an alternative, for energy-saving reasons, and / or if by chance there is a lot of short-term upward drift of air quality parameters, it may not be dangerous, if the air quality parameter levels have quickly dropped to just below the trigger level, then the dilution ventilation command signal 31 rapidly decreased to the lowest level may be more advantageous. 这样,可能也会有利的是,使不同阶跃或输出特性与每一空气质量参数相关联。 Thus, it may also be advantageous to make the output characteristics with different step or each air quality parameter is associated. 结果,基于哪种(哪些)空气质量参数触发了对更多稀释通风的需要,输出控制特性将会不同。 The results, based on which (what) air quality parameter triggers the need for additional dilution ventilation output control characteristics will be different.

[0110] 信号处理控制器块530的输出信号还可以被用于基于感兴趣的溢出检测、空气污染物之一的快速上升、或者空气质量参数的水平,来改变采样序列,以更紧密地观察。 [0110] The signal processing controller block 530 may also be used for the output signal based on an overflow detection, rapid rise in one of the air pollutants, or the level of air quality parameters of interest to change the sampling sequence, in order to more closely observe . 在这个替换方法中,可以通过控制逻辑块510所用的信号处理控制器块输出信号512来改变从环境20进入共享传感器的空气采样的序列,以便在特定空间20中的所检测到的感兴趣的事件的时间段期间,基于潜在的时间上的基础来修改采样序列。 In this alternative method, by controlling the logic block output signal of the signal processing controller block 510, 512 used to change the sequence of the sampled air from the environment into the shared sensor 20, so that the space 20 is in particular of interest detected during the time period of the event, based on the basis of the potential to modify the sampling time sequences. 基于看到控制信号或软件变量512的值增大到某个较高的触发水平或表现出某种信号模式,例如幅度的快速上升, 控制逻辑块510可以提高检测到该事件的空间的空气采样的频率。 See the value of the control signal based or software variables 512 increases to a higher trigger level or show some signal patterns, such as the rapid rise of the control logic block 510 can improve the air space of the event is detected sampling frequency. 作为替换或者附加地, 受影响的空间周围的区域可以接着被快速采样,或以较高频率被采样,以寻找对其它空间的空气污染物的扩散。 Alternatively or additionally, the space around the affected area can then be quickly sampled or sampled at a higher frequency, to find space for the diffusion of other air pollutants. 在本发明的上下文中,幅度的快速上升可以被定义为,例如由于挥发性有机化合物例如清洁剂的溢出而导致的,值在小于5分钟内突然增大到诸如正常触发水平的许多倍的水平。 In the context of the present invention, the fast rise can be defined as, e.g., volatile organic compounds, for example due to overflow resulting detergent, suddenly increases to a value less than 5 minutes, such as within the normal level of the trigger level many times .

[0111] 可以用图1、图2、或图6的采样系统来实现采样或控制序列时的这种改变。 [0111] is illustrated in Figure 1, Figure 2, Figure 6 or sampling system to achieve control of sampling or when such a change sequence. 如果例如使用了图2的系统,则很有可能由信号处理控制器块210来执行对事件的检测,并且由控制逻辑块310A、310B、310C和310D来执行序列的改变。 If, for example using the system of Figure 2, it is likely that by the signal processing controller block 210 performs detection of an event, and by the control logic block 310A, 310B, 310C and 310D to perform the change sequence.

[0112] 如果在一个或若干个空间中检测到某种类型的事件,则可以实现的控制序列的另一种改变是:通过一次将若干个空间的空气采样相加以测量若干个房间的混合采样,来改变采样序列。 [0112] Another change if one or several spaces detects certain type of event, it is possible to realize the control sequence is: by a plurality of air sampling phase space of the room is measured several mixed sample to change the sample sequence. 可以通过一次接通一个或多个螺线管接通以收集受影响区域的混合采样或靠近受影响区域的多个区域的混合采样,以快速寻找进入其它区域的潜在溢出,从而实现上述操作。 You can turn on one or more once the solenoid to collect samples by mixing the affected area or multiple areas near the affected area of the mixed sample, in order to quickly find potential spillover into the other areas in order to achieve the above operations. 可以用与上述相同的方式来实现该操作,但其将涉及接通多个螺线管阀,例如图1 中的螺线管161、162、263和164,或者图2中的螺线管361A、362A、363A和361B。 Can be used in the same manner as described above to implement this operation, but it will involve a plurality of solenoid valves is turned on, for example, in Figure 1 the solenoid 161,162,263 and 164, or in Figure 2 the solenoid 361A , 362A, 363A and 361B.

[0113] 存在几种不同的方法可以用于创建混合或复合空气质量参数信号,所述混合或复合空气质量参数信号可以仅用于进行监控,或用于控制目的,例如稀释通风命令信号31或外部空气命令信号1075。 [0113] There are many different methods can be used to create hybrid or composite air quality parameter signal, the mixed or composite air quality parameter signal that can be used only to monitor, or for control purposes, such as dilution ventilation command signal 31 or outside air command signal 1075. 可以至少部分地通过以下部件来实现这些混合信号:图1、图2、 图4、或图6的相应信号处理控制器块130、210、530、或1130 ;建筑物控制系统180 ;或图4 的输出控制块MOA ;以及图6和图9的外部空气流控制器1200。 May be at least in part by the following means to achieve these mixed signals: Figure 1, the signal processing controller block corresponding to FIG. 2, FIG. 4, or Fig 6, 130,210,530, or 1130; building control system 180; Fig. 4, or The output control block MOA; and an external air flow controller 1200 in FIG. 6 and FIG. 9. 这些混合信号,尤其是用于控制的信号,具有两个重要的方面。 These mixed signals, in particular for control signals, has two important aspects. 一个组件涉及信号类型,其还影响控制方法,例如两状态、三状态、或多状态、连续变量,或影响涉及不连续和连续功能两者的组合的信号或控制方法。 Relates to a component signal type, which also affects the control methods, such as two state, three state, or state, continuously variable, or affect the signal or control a method involving both discontinuous and continuous function of the combination. 另一个方面涉及信号的组成或多个传感器信号如何被组合或混合以生成空气质量参数反馈、或监控信号,以及通风、外部空气或其它控制和命令信号。 Another aspect relates to how the composition of a signal or a plurality of sensor signals are combined or mixed to produce an air quality parameter feedback, or monitoring signals, as well as ventilation, air or other external control and command signals.

[0114] 例如可以用于稀释通风命令信号31的混合空气质量参数信号的一个实施例是两状态控制信号,通过该信号,稀释通风命令信号31被维持在其最小水平,例如对应于2ACH 或4ACH的稀释通风值(或者某些其它合适的较低值,这取决于什么适合于被监控的环境), 除非发生触发事件,其中所述触发事件可以包括传感器信号,尤其是诸如TVOC、CO、或微粒之类的空气污染物传感器的信号超过阈值或触发值。 [0114] For example one embodiment may be used for dilution ventilation command signal 31 is mixed air quality parameter signals is a two-state control signal through the signal, the dilution ventilation command signal 31 is maintained at its minimum level, e.g., corresponding to 2ACH or 4ACH The dilution ventilation values (or some other suitable low value, depending on what is suitable for the environment to be monitored), unless the trigger event occurs, wherein the triggering event may include a sensor signal, in particular such as TVOC, CO, or signal particulate air pollutants like sensor exceeds a threshold or trigger value. 如果传感器信号仅包括一种空气质量参数,则可以定义简单的阈值或触发值(与要对其采取某种行动的所感测的空气质量参数的值相对应)。 If the sensor signal includes an air quality parameters, you can define a simple threshold or trigger value (the value you want to take some action on its air quality parameters sensed corresponds). 作为替换方案,所述触发事件可以包括信号以某种方式与指定的信号模式匹配,诸如水平快速增大,即使没有达到所指定的阈值水平。 As an alternative, the triggering event may include a signal in some way with the specified signal pattern matching, such as the level increases rapidly, even if does not reach the specified threshold level. 触发事件还可以由一组或多组阈值和信号模式的对的组合构成,上述中的任何一个都可以构成触发事件。 Trigger event may also be constituted by a combination of one or more sets of thresholds and signal pattern, any one of the above may constitute a triggering event.

[0115] 更典型地,如果采用多种传感器空气质量参数(例如来自共享传感器120和/或本地房间传感器25A),则可以将触发事件定义为以下中的任何一个:所采用的传感器信号超过阈值、与一个信号模式匹配、或满足潜在的多组阈值水平和信号模式的对中之一的条件。 [0115] More typically, if using a variety of sensors air quality parameters (such as from the shared sensors 120 and / or the local room sensors 25A), you can trigger event is defined as any one of the following: a sensor signal exceeds the threshold value used , with a signal pattern matcher, or to meet the conditions of one of the plurality of sets of threshold potential level and signal pattern. 每个传感器信号很可能具有不同阈值水平和/或信号模式,所述不同阈值水平和/或信号模式对应于所感测的空气质量参数的合适值,其中所述合适值基于该信号的被接受的水平,此水平与对于所述感测的空气质量参数来说的健康、舒适度、或其他重要性准则之一或组合有关。 Each sensor signal is likely to have a different threshold level and / or signal pattern, said different threshold levels and / or signal pattern suitable air quality parameter values sensed in, wherein the appropriate value based on the signal accepted level, this level of air quality parameters with respect to said sensed for health, comfort, or a combination of the relevant criteria or other significance. 例如,PIDTV0C传感器可能具有大约0. 5PPM至2PPM的阈值水平。 For example, PIDTV0C sensor may have a threshold level of about 0. 5PPM to 2PPM. 该范围内的水平感测其OSHA TLV(阈值极限值)之下的多种材料,同时仍然通过停留在不那么有害的材料(例如酒精蒸汽)的正常水平之上而不生成很多错误告警。 - Being in this range were measured for a variety of materials OSHA TLV (threshold limit value) below, while still staying in by above less harmful materials (e.g., alcohol vapor) without generating a lot of normal levels of false alarms. 如果使用在0. 3至2. 5 微米范围内进行测量的微粒计数器,则可以设定这样的水平,所述水平在正常情况下不会被超过(例如在每立方英尺1. 0至5百万个微粒的范围中),而仍然拾取通过被监控的空间中的某种事件产生的烟或某种类型的悬浮物的发展。 If measured in the 0.3 to 2.5 micron range particle counter, it is possible to set such a level, the level will not be exceeded under normal conditions (e.g. 1.0 to 5 one hundred per cubic foot 10,000 microparticles range), and still pick up the space to be monitored through the development of a certain event generated in some type of smoke or suspended solids. 可以基于对空间的过滤的水平来设定具体的水平,即,过滤越多,可能被使用的水平就越低。 May be based on the level of spatial filtering to set a specific level, i.e., the filter, the more the low levels may be used. 其它传感器,例如一氧化碳、氨、氮氧化合物、臭氧、或其它有毒气体传感器可以直接被设定为用于感测化合物的TLV或者在典型的操作中通常将不会被达到的较低水平。 Other sensors, such as carbon monoxide, ammonia, nitrogen oxides, ozone or other toxic gas sensors can be set to be used for sensing a compound TLV or typical operation would not normally be reached lower levels.

[0116] 虽然以连续动作或可变信号来典型地进行基于C02的需求控制通风,但也可以通过以下方式来实现更简单的控制形式:当房间中的C02水平超过某个阈值水平(例如1000PPM)、或超过C02的800PPM至1500PPM范围内的值、或高于C02的周围室外浓度400PPM 至1000PPM的值时,增大通风。 [0116] Although the continuous action or variable signals typically C02-based demand control ventilation, but can also be achieved in the following ways simpler forms of control: When the room in the C02 level exceeds a certain threshold level (eg 1000PPM ), or more than 800PPM C02 to a value within the range of 1500PPM, C02 or higher than the surrounding outdoor concentration of 400PPM to 1000PPM value, increased ventilation. 由于C02在几乎所有情况下都不被认为是有害空气污染物, 因此C02的这些阈值不以任何方式涉及C02的健康极限,但是C02是每人充足的外部空气等级的代理,这是由于空间中的C02对室外水平的微分值也涉及空间中的外部空气通风量除以人数,有时也被称为cfm外部空气每人。 Because C02 In almost all cases are not considered hazardous air pollutants, these thresholds C02 does not in any way related to health limit C02, but the C02 is sufficient levels of outside air per person agency, which is due to space The C02 level of the differential value of the outdoor space are also involved in the outside air ventilation rate divided by the number, sometimes called cfm outside air per person. 工程师组织ASHRAE(采暖、制冷、和空调工程师协会)已经设定了用于外部空气通风值的各种指导方案,其可以对于不同类型的设施而改变,但通常期望在每人12cfm到每人15cfm的范围内,这对应于高于建筑物外部的环境水平的大约425PPM至大约875PPM,其中建筑物外部的环境水平典型地可以在300PPM到500PPM 之间。 Engineers ASHRAE (heating, cooling, and air-conditioning Engineers) has been set up for a variety of mentoring programs outside air ventilation values, which can be for different types of facilities varies, but usually expect each person to person 15cfm 12cfm within the range, which corresponds to a level higher than the environment outside the building about 425PPM to about 875PPM, wherein horizontally outside the building environment typically be between 300PPM to 500PPM.

[0117] 作为替换方案,触发条件可以包括两个或更多感测的空气质量参数的组合,每一空气质量参数均达到或超过对于该化合物的给定水平或满足某种信号模式条件。 [0117] As an alternative, the trigger conditions may include two or more combinations of sensed air quality parameters, each air quality parameters are met or exceeded for a given level of the compound or to meet certain conditions of signal patterns. 例如,个别地,精细微粒的适中水平(例如每立方英尺1.5百万个微粒)、TVOC的适中水平(例如0. 5PPM)、或漂移到大于85度的温度的适中水平本身可能不会触发对于增大稀释通风的需要。 For example, individually, moderate levels of fine particles (for example, 1.5 million particles per cubic foot), TVOC moderate level (eg 0. 5PPM), or drift to a temperature greater than 85 degrees moderate level itself may not trigger for increased dilution ventilation needs. 然而,满足前面条件的全部这三种空气质量参数的组合可以指示着火或爆炸,这将明确地需要增大通风水平。 However, the combination of all three front air quality parameters satisfy the condition may indicate a fire or explosion, which will clearly need to increase the level of ventilation.

[0118] 涉及多个感测的空气质量参数的触发条件的另一种实施方式可以包括加性的触发条件。 [0118] involving multiple sensed air quality parameters of the trigger conditions may include another embodiment additive trigger conditions. 这种情况的一个好的示例与对危险材料的暴露有关。 A good example of this situation and the risk of exposure to the material. OSHA表明,可以通过相加每种单个化合物的水平对其TLV的分数来计算混合气体的有效TLV,以取得组合后的混合物对组合后的TLV的分数。 OSHA show, by adding a level of each of its individual compounds TLV scores to compute the effective TLV mixed gas, in order to obtain a mixture of the combined TLV the combined scores. 例如,如果系统检测到一氧化碳处于阈值限制值的65%,并且感测到二氧化硫处于其TLV值的70 %,则虽然单独来看没有化合物会触发该系统,但它们二者 For example, if the system detects carbon monoxide in the 65% threshold limit values, and sensed TLV sulfur dioxide in 70 percent of its value, then there is no point of view, although the compounds alone will trigger the system, but they are both

30的组合将处于组合后的TLV的135%,这样将组成触发条件。 Assembly 30 will be at 135% of the combined TLV, so that the composition of the trigger condition. 为了实施该方法,每一感测的感兴趣的空气质量参数将基于其阈值而被个别地比例缩放,然后加在一起,并且为加和后的结果设定阈值触发。 To implement this method, each air quality parameters of interest to be sensed based on the zoom ratio of the threshold individually, and then added together, and the threshold value is set to plus and the results after triggering.

[0119] 例如,可以通过以下操作来实现上述方案:首先选择主导参数来执行(例如C02) 的通风控制关闭,其后基于主导参数的触发水平与附加参数的触发水平的比率对其它参数(微粒、TVOC等)进行比例缩放而将其包括在复合反馈信号中。 [0119], for example, can be achieved by following the above scheme: First select the dominant parameters to perform (such as C02) ventilation control turned off, then the trigger level trigger level based on the dominant parameters and additional parameters of the ratio of the other parameters (particle , TVOC, etc.) will be scaled and included in the composite feedback signal. 例如,如果C02是主导参数,具有IOOOppm的触发水平(设定点),TVOC是次要参数,具有30ppm的触发水平,则在此情况下将TVOC对C02进行“归一化”或比例缩放的乘数是: For example, if the C02 is the dominant parameters, with IOOOppm trigger level (set point), TVOC is secondary parameters, with 30ppm trigger level, then in this case the C02 TVOC on a "normalized" or scaled multiplier is:

[0120] 在这些条件下,将TVOC读取乘以33. 33,其后将其加到C02信号上,从而用于C02 的设定点或触发点为IOOOppm的控制器可以用于将TVOC限制到30ppm。 [0120] Under these conditions, the TVOC reading multiplied by 33.33, whereafter it is applied to the C02 signal, thereby setting points or trigger point C02 for IOOOppm controller may be used to limit the TVOC to 30ppm. 作为替换,可以对这两个信号彼此之间进行高选择,以创建混合空气质量参数信号,该信号其后可以与信号阈值水平或控制设定点进行比较,用于更简单的操作。 Alternatively, these two signals can be high selectivity between each other, to create a mixing of the air quality parameter signal, which subsequently can be compared to a threshold signal level or the control set point, for simpler operation.

[0121] 关于可以如何设定触发条件的另一种变化方案是,使一个或多个所感测的空气质量参数的触发条件基于某些其它空气质量参数或空间的某些其它条件而变化或改变。 [0121] on how you can set another variation, the trigger condition is sensed so that the trigger condition of one or more air quality parameters based on some other conditions, or some other air quality parameters vary or change the space . 例如,触发条件可以基于占用情况而改变,如果空间中没有人,则可以将用于某些空气质量参数的触发条件稍微增大,以通过对于非占用时间段允许较低的通风等级和较高的污染物水平来节省更多的能量。 For example, the trigger condition may be changed based on occupancy, if no space, it can be used to trigger certain conditions of air quality parameters increased slightly, by the time period allowed for the recessive lower and a higher level of ventilation The contaminant levels to save more energy. 其后,当例如通过占用存储器或光开关、卡访问系统、或其它手段(例如在空间中检测C02的变化)以某种方式检测或确定有人在空间中时,可以降低触发水平。 Thereafter, when, for example by occupying memory or optical switch, card access systems, or other means (such as detecting changes in space C02) in some way to detect or determine someone in space, you can reduce the trigger level. 还可以基于例如关于房间或空间中的空气质量参数的增大或减小的关注而对触发水平进行手动本地改变、或远程强制覆盖改变。 You can also increase or decrease based on the example of a room or space concerns about air quality parameters while the trigger level manually change locally or remotely mandatory coverage change. 作为替换方案,可以分别由图1、图2、图4、或图6的相应信号处理控制器130、210、530、或1130、某些其它系统(例如建筑物自动化或建筑物控制系统180、或跟踪空气流控制系统)来自动改变该水平。 As an alternative, may be made to Figure 1, the signal processing controller corresponding to FIG. 2, FIG. 4, or Fig 6, 130,210,530, or 1130, some other system (such as a building or building automation control system 180, respectively, air flow control or tracking system) to automatically change the level.

[0122] 最后,受任何其它组条件影响的、或被其它系统作用的、作用于任意数量的所感测的空气质量参数的、所感测的空气质量参数值或传感器信号模式条件的任意数量的不同逻辑或布尔组合可以用于创建混合空气质量参数信号,所述混合空气质量参数信号可以与合适的触发条件一起使用,以创建两状态混合反馈信号,其可以通过增大稀释通风命令31来要求增大的稀释通风。 [0122] Finally, by any other group influences, or other systemic effects, acting on any number of air quality parameters are sensed, and that any number of measuring air quality parameter values or sensor signal pattern conditions different sense Boolean logic or a combination can be used to create hybrid air quality parameter signal, said mixed air quality parameter signals can be used with an appropriate trigger conditions to create the mixed state of the two feedback signals, which may be increased by increasing the dilution ventilation request command 31 large dilution ventilation.

[0123] 存在大量控制技术,其可以例如使用输出控制块MOA来生成命令31,以便改变所监控的环境20内的通风量,从而充分稀释感测到的空气质量参数,以防止空气传播的空气质量参数的浓度超过特定水平。 [0123] the presence of a large number of control techniques, which may for example output control block generates commands MOA 31, so as to change the amount of ventilation within the monitored environment 20, thereby being sufficiently dilute to the sensed air quality parameters, in order to prevent airborne air mass concentration parameter exceeds a certain level. 从控制逻辑或算法的角度来说,人们可以使用的任意方法都被看作是本发明的各个方面,无论该方法是涉及连续或不连续控制功能、模糊逻辑、比ί列一禾只分一微分功能(proportional-integral-derivativefunction)、前馈功能、自适应控制的开环或闭环策略,或是控制系统设计领域中的技术人员所知的其它技术。 Control logic or algorithm from the point of view, one can use any of the methods are considered as aspects of the present invention, relates to whether the process is a continuous or discontinuous control functions, fuzzy logic, than ί Wo only a fraction of a column Differential function (proportional-integral-derivativefunction), feed-forward function, open or closed loop adaptive control strategy, or control system design in the field of skill in the art of other technologies.

[0124] 图7A示出当信号处理控制器130被配置为提供两状态控制功能时,与命令31相关联的稳态(steady state)水平的一种可能的情形,提供所述两状态控制功能使得当例如与环境20有关的由功能块537A所创建的一个或多个混合或复合空气质量参数信号转变为高于一个或多个所建立的触发值时,稀释通风命令信号31从正常水平或ACH(每小时换气次数)值增大到增强的稀释模式水平。 [0124] Figure 7A shows when the signal processing controller 130 is configured to provide a two-state control function, and a steady state (steady state) level of 31 possible scenarios associated with the command, to provide the two-state control function such that when the trigger value such as one or more hybrid or composite air quality parameter signal 20 related to changing circumstances created by the function block 537A is above one or more established, the dilution ventilation command signal 31 from a normal level or ACH (air changes per hour) value increased to enhance the level of dilution mode. 反之,当一个或多个混合空气质量参数信号的值从合适的触发值之上的水平转变为该值之下的水平时,命令31将降回到其正常稳态空气流或ACH值。 On the contrary, when the value of one or more signal quality parameters of the mixed air from a suitable value above the trigger level for the value below the transition level, command 31 will fall back to its normal steady-state value of the air flow or ACH. 图7A没有涉及在命令31从正常ACH值转变为增强的稀释模式、或从增强的稀释模式转变为正常ACH值时所述命令31的时间响应,因为这是一种特定控制技术的功能, 所述特定控制技术用于在确保在系统内维持了稳定性的同时进行这样的转变。 Figure 7A not involved in the command 31 for transitioning from the normal ACH value enhanced dilution mode, or transition from the enhanced dilution mode to a normal ACH value of the time response command 31, because it is a function of the particular control technique, the said specific control technique is used to ensure the maintenance of the stability in the systems for performing such transformation. 作为本发明的一个实施例,图7A的两状态方法对于在许多应用中使用来说是可接受的。 As an embodiment of the present invention, two-state method of FIG. 7A for use in many applications is acceptable. 然而,在某些情况下,将通过包括防止命令31或其他命令诸如外部空气命令信号1075震荡的措施而使图7A所描绘的用简单切换机制所实现的系统稳定性受益。 However, in some cases, will be prevented by including a command or other command system 31 with a simple handover mechanism stability achieved depicted 7A measures such as outside air command signal 1075 shocks leaving benefit FIG.

[0125] 作为本发明的一个实施例,当命令31从正常ACH值(例如1ACH-4ACH)转变为增强的稀释模式(例如10ACH-15ACH)时,命令31将例如被输出控制块MOA锁存或者成为被固定在该较高的值,从而如果在该转变之后,所测量的空气质量参数降低到触发值之下,则换气率将仍然保持是高的。 [0125] As an embodiment of the present invention, when the command 31 transitioning from the normal ACH value (e.g. 1ACH-4ACH) for enhanced dilution mode (e.g. 10ACH-15ACH), the command 31 is output to the control block such as the latch or MOA become the values are fixed at the higher, so that if after the transition, the measured air quality parameter drops below the trigger value, the ventilation rate will remain high. 这种方法可以伴随某种形式的通知机制,所述通知机制来自建筑物控制系统180、或采样系统100、300、400、1100、或经由互联网连接171、或来自空气流控制器30或空气流控制器30所连接的该系统的某些其它部件,所述通知机制将向维护人员或其它员工告警:已经超过了触发值,从而可以手动重置该信号处理控制器。 This approach may be accompanied by some form of notification mechanisms, the notification mechanism 180, or the sampling system from building control systems 100,300,400,1100, or via the Internet 171, or from the air flow controller 30 or the air flow Certain other components of the controller 30 is connected to the system, the mechanism will notify maintenance personnel or other personnel alarm: has exceeded the trigger value, which can be manually reset the signal processing controller.

[0126] 作为替换实施例,替代锁存命令31,当所感测的或混合的空气质量参数的值超过所建立的触发值时,人们可以应用图7B所示的滞后功能,其描述了例如与命令31相关联的稳态水平的另一情形,其中,提供了两个不同的触发或转变点(输入低触发和输入高触发)。 [0126] As an alternative embodiment, replace the latch command 31, when the trigger value is a value of the sensed air quality parameter or blended exceeds established, one can apply a hysteresis function shown in Fig. 7B, and which is described e.g. Another case of the steady state level of the command 31 is associated, which provides two different triggering or transition point (low input trigger and the input high trigger). 在此,当命令31处于与正常ACH值对应的水平时使用输入高触发,而当命令31处于与增强的稀释模式对应的水平时使用输入低触发。 Here, when the command 31 using the input in the normal ACH value corresponding to a high level when the trigger, and when the command 31 is enhanced dilution mode with a level corresponding to the use of low input trigger.

[0127] 用于稀释通风命令信号31或推导自空气质量参数信号的其它混合监控或控制信号的优选信号类型和所得的控制方法涉及使用三状态信号来实现三状态控制方法。 [0127] for the dilution ventilation command signal 31 or be derived from the signal type and is preferably obtained by the process control monitoring or other control signal mixing air quality parameter signal relates to the use of three-state signal to achieve a three-state control method. 与具有两个输出水平(例如典型地用于净化(purge)的高水平、以及低正常操作水平)的前述信号类型和控制方法不同,本方法具有三个输出水平。 And the aforementioned signal type and control approach has two output levels (e.g. high levels typically used Purification (purge), and the normal operation of the low level) is different, this method has three output levels. 这三种水平的一个典型应用是,与前述相同的两个水平,并且添加中间水平,所述中间水平不是用于溢出(所感测的空气质量参数的水平中的极度越界),而是用于控制期望被降低的所感测的空气质量参数的更适中的水平。 A typical application of the three levels is the same as the foregoing two levels, and add an intermediate level, the intermediate level is not used for overflow (horizontal air quality parameters measured in the sense of extreme bounds), but for More modest levels expected to be reduced by controlling the sensed air quality parameter. 例如,如果感测到来自TVOC检测器的IPPM和10PPM之间的水平,则系统将增大适中的水平,例如从3ACH的最小水平增大到6ACH的水平。 For example, if the sensed level between 10PPM from IPPM and TVOC detector, the system will increase the moderate levels, e.g., from the minimum level to the level 6ACH 3ACH increases the. 然而,如果TVOC检测器感测到10PPM之上的水平,则系统将进入净化模式,该净化模式可能具有10ACH至15ACH的稀释通风。 However, if the TVOC detector sensed 10PPM above the level, the system will enter purge mode, the purge mode may have 10ACH to 15ACH dilution ventilation. 这种方法限制了用于适中空气质量参数水平的能耗,并且降低了以下情况发生的机会: 如果多个房间处于这种适中水平,则过多的房间被命令为最大换气率(ACH)值使得超过建筑物的总系统空气流容量。 This approach limits the energy consumption for a moderate level of air quality parameters, and reduces the chance of the following occurs: if a plurality of rooms in such a modest level, the room is excessive command maximum ventilation rate (ACH) making the total value of more than building the system air flow capacity. 三水平方法或其它多水平方法(或者VAV方法)的另一优点在于,其减少了实现不稳定状况的机会,在所述不稳定状况中,由于随着系统通过超过稳定操作状况所需的量而交替地增大并超调(overshoot)、然后降低并欠调(undershoot)所期望的稀释空气流命令水平,所述空气质量参数的稳态释放被交替地净化为低的值、然后缓慢往回增进,导致房间空气流会上下变化。 Three levels of multi-level methods, or other method (or methods VAV) Another advantage is that it reduces the chance of achieving the unstable situation in the unstable condition, because the amount required as the system by more than a stable operating conditions alternately increase and overshoot (overshoot), and then reduce undershoot (undershoot) the desired level of the dilution air flow command, the steady-state release of air quality parameters are alternately purified to a low value, and then slowly to Back promotion, resulting in lower air flow at the change room.

[0128] 可以将所述三状态控制方法从三个输出状态扩展到用于稀释通风命令信号31的任意数量的输出状态,以提供用于空间的稀释通风的不同水平。 [0128] can be the three-state control method of output from the three state extended to any number of output states for the dilution ventilation command signal 31 to provide a space for different levels of dilution ventilation. 最终,使用诸如来自共享传感器120和/或本地房间传感器25A之类的多个感测信号的方法中的任何方法都可以如上所述用于所述的两状态的方法,并且还可以通过添加用于中间或其他输出信号状态的另一组或另外的多组触发水平和比较器而用于三状态或其它多状态控制方法。 Method final, such as the use of a plurality of sensing signals from the shared sensors 120 and / or the local room sensor 25A or the like in any method as described above may be used for the two states, and may also be used by adding in the middle of the state or other output signal of another group or another multi-trigger level and the comparator group was used in three other state or multi-state control methods. 此外,可以把来自多个参数的比较器的输出加在一起,从而例如如果越过了用于两个空气质量参数的第一阈值或中间阈值,则将输出信号索引(index)到三状态信号的最大流或信号状态,或将其索引到多个流或多个状态空气质量参数信号中的第三流水平或信号状态,而不是仅索引到第二或中间水平。 Further, the output from the comparator of the plurality of parameters are added together, so, for example if the first threshold value or over the intermediate threshold is used for both air quality parameters, the three-state signal is output signal index (index) to the The maximum flow or signal state, or to an index to the plurality of streams or a plurality of state parameters of air quality in the third stream signal level or signal state, rather than just an index into the second or intermediate level. 此外,可以存在这样一些空气质量参数,由于这些空气质量参数的危险级另IJ,它们不需要或仅需要很少的其它中间阈值或触发级别,甚至越过“第一”阈值水平就要求使用高的多的或潜在的最大流或信号状态。 In addition, there may be some air quality parameters, due to the risk level of air quality parameters of these other IJ, they do not require or require very little other intermediate threshold or trigger level, even over the "first" threshold level would require the use of high more or potential maximum flow or signal status. 作为替换方案,在一个优选实施例中,可以将空气质量参数对于彼此之间比例缩放,其后将它们如上所述相加在一起,以创建混合空气质量参数信号,其可以仅与两个或更多阈值水平中的一组进行比较。 As an alternative, in a preferred embodiment, the air quality parameter may be proportional to each other for zooming, followed by adding them together as described above, to create the mixed air quality parameter signal, which may be only two or More of a threshold level were compared. 后者的方法对于多个输出状态或当期望改变阈值水平时是方便的,仅需要修改一组阈值。 The latter method for a plurality of output status or when it is desired to change the threshold level is convenient, it is necessary to modify only a set of thresholds.

[0129] 用于创建和使用混合空气质量参数信号(例如稀释通风命令信号31)的另一优选类型的信号和有关的控制方法是,使用连续可变的信号,其可以用于实现可变空气量或VAV 控制方法。 Signal and the associated control method according to another preferred type of [0129] is used to create and use a mixed air quality parameter signals (e.g., dilution ventilation command signal 31) is to use a continuously variable signal, which may be used to implement a variable air volume or VAV control methods. 利用这种信号类型和控制方法,一旦所感测的空气质量参数信号达到某个触发水平或与某种信号模式匹配时,稀释通风命令信号31或对应的稀释通风反馈信号538A就可以用连续方式从最小水平一路增大到最大水平,所述最小水平将与两状态或多状态方法的最小状态输出相匹配,所述最大级别将对应于两状态或多状态方法的最大水平。 With this type of signal and control method, once the sensed air quality parameters measured signal reaches a certain trigger level, or a signal pattern is matched, the dilution ventilation command signal 31 or the corresponding dilution ventilation feedback signal 538A can be used in a continuous manner from all the way to the minimum level to increase the maximum level, the minimum level to match with the two-state or output state of minimum state method, the maximum level corresponding to the two-state or multi-state method of the maximum level. 可以用如上所述的控制方法通过以下操作来实现这种有效“无限状态”的方法:从例如来自共享传感器120和/或本地房间传感器(例如25A)的多个所感测的空气质量信号创建混合空气质量参数信号,所述多个所感测的空气质量参数可以按照任何方式被混合或组合。 The control method described above can be used by the following operation to achieve this effective "infinite state" method: air quality from measured signal from the shared sensors 120 such as a plurality and / or a local room sensors (e.g., 25A) being created by mixing air quality parameter signal, said plurality of air quality parameters sensed can be mixed in any manner or combination. 如前所述, 各个空气质量参数信号可以分别被作用,其后相加或被高选择,以形成混合的所得信号。 As described above, each air quality parameter signal may be acted separately, followed by the addition or a high selectivity, resulting in the formation of a mixed signal. 然而,采用连续可变信号,通常优选的是,在利用图4的输出控制块MOA将控制环路、滞后、或其它功能应用于例如混合的反馈信号538A之前,首先例如利用多输入功能块537A对例如来自图4的比例缩放和偏置块561A、562A、534A、535A、或536A的输出的被比例缩放、偏置、 或以其他方式被修改的空气质量参数信号进行相加或高选择。 However, the use of a continuously variable signal, it is generally preferred in the use of the output control block diagram of the control loop MOA 4, hysteresis, or other function is applied, for example prior to mixing with the feedback signal 538A, for example, using the first multiple-input function block 537A Figure 4, for example, from the ratio of the scaling and bias block 561A, 562A, 534A, 535A, or 536A is the output of scaling, offset, or otherwise modified for adding air quality parameter signal or high selectivity. 此外,多输入功能块537A还可以在组合各自被比例缩放的信号之前或之后,将输入的空气质量参数信号之间的强制覆盖或低选择功能应用于这些信号,或者将其它线性、非线性或布尔逻辑功能应用于这些信号。 In addition, multiple input function block 537A can also be a combination of the respective scaled before or after the proportional signal, select mandatory coverage or low air quality parameter signal between the input applied to these signals, or other linear, nonlinear, or Boolean logic function applied to these signals.

[0130] 输出控制块MOA还可以将线性或非线性功能应用于混合空气质量参数信号,例如538A。 [0130] output control block MOA also be linear or non-linear function of the signal applied to the mixed air quality parameters, such as 538A. 例如,在线性关系的情况下,可以使用偏置和简单比例缩放或增益因子以及最小和最大箝位,从而稀释通风反馈信号538A增大超过最小命令信号值,稀释通风命令信号31 也将增大,直到其达到所允许的最大命令信号值。 For example, in the case of linear relationship, you can use a simple scaling or offset and gain factor and the minimum and maximum clamp, thereby increasing dilution ventilation feedback signal 538A command signal exceeds a minimum value, dilution ventilation command signal 31 will increase until it reaches the maximum allowed value of the command signal. 使用连续可变信号状态的其中另一原因在于创建受监控的空间或建筑物内的室内环境质量的闭环控制,从而防止可能在某些情况下由两状态或甚至多状态方法生成的振荡控制模式。 Use continuously variable signal state wherein another reason is to create a closed-loop control of indoor environmental quality space or building monitored inside, thereby preventing a state may be provided by two methods, or even up state in some cases generated oscillation control mode . 采用连续可变信号状态,可以实现可变空气量(VAV)控制方法,从而增大的通风水平可以以稳定方式被维持在最小命令信号水平和最大命令信号水平之间,特别是在存在空气质量参数的粗略恒定发射水平的情况下。 Using a continuously variable signal state, can achieve a variable air volume (VAV) control method, thereby increasing the level of ventilation can be maintained between the minimum and maximum levels of the command signal commands the signal level in a stable manner, especially in the presence of air quality situation roughly constant emission levels under the parameters. 该方法可以用于调节空气质量参数的水平(例如TV0C、微粒、或处于某种设定点的其它参数),而不是将其驱动到最小级别,所述最小级别被证明就运行在高通风达到很长时间段的能量消耗而言是昂贵的。 This method can be used to adjust the level of air quality parameters (e.g. TV0C, microparticles, or in some other parameter set point), instead of being driven to a minimum level, said minimum level is proven to achieve operating at high ventilation Energy consumption in terms of a very long period of time is expensive. 当空气质量参数不是特别危险的参数并且可以被设定为被维持在不会产生健康影响的水平时(例如对于微粒),该方法也是适合的。 When the air quality parameter is not particularly dangerous parameter and may be set to be maintained at a level no health effects when (for example, fine particles), which are also suitable. 更具体地说,通过使用包括多个空气质量参数的混合空气质量参数信号,可以将空间中的质量维持为“清洁水 More specifically, by using a mixed air quality parameter signal comprises a plurality of air quality parameters, the quality of the space can be maintained at "clean water

In this method, may be mixed air quality control feedback signal to the set point, the set point representation space combined state of cleanliness of air or measured.

[0131] 图8A和8B示出输出控制块MOA的控制逻辑和功能的潜在实施例,所述输出控制块MOA包括闭环系统900,以便通过以下方式提供稀释通风控制:在规定的极限内以连续(或VAV)方式改变环境内的换气率或有效地改变送风空气流等级,以如上所述防止所感测的空气质量参数(例如TV0C)的水平或混合空气质量参数信号超过所规定的值。 [0131] Figures 8A and 8B show the control logic and functionality of the potential embodiments of the output control block MOA, MOA said output control block 900 comprises a closed loop system, in order to provide dilution ventilation by the following control: within the limits specified in a continuous (or VAV) way to change the ventilation rate within the environment, or to effectively change the blower air flow level, as described above in order to prevent the sensed air quality parameters (e.g. TV0C) level or mixing air quality parameter signal exceeds a predetermined value . 在此,从空气质量参数设定点901减去传感器反馈908,以便(由误差级902)来创建误差信号914, 其中所述空气质量参数设定点901表示系统900所要控制的混合的一组参数或所感测的空气质量参数的水平,所述传感器反馈908可以是图4的稀释通风反馈信号538A。 Here, subtracting from the air quality parameter set point 901 feedback sensor 908, so that (by the error level 902) to create an error signal 914, wherein the air quality parameter set point 901 represents the mixing system to be controlled, a set of 900 level parameter or the sensed air quality parameters, the sensor 908 may be a feedback Figure 4 dilution ventilation feedback signal 538A. 控制时钟903作用于误差信号914,以便创建由最小ACH箝位块904和最大ACH箝位块905限定的项,从而产生命令信号920。 903 acting on the control clock error signal 914, in order to create the smallest ACH ACH clamp block 904 and clamp block 905 defines the maximum items, thereby generating a command signal 920. 取决于所感测的空气质量参数信号908和设定点901的特性和源,命令信号920可以表示图4的稀释通风命令信号31,或其它相关的空气流命令或控制信号,例如外部空气流命令信号1075。 Depending on the measured air quality parameter signal 908 and the set point and the sensed characteristic of the source 901, the command signal 920 may be represented in Figure 4 dilution ventilation command signal 31, an air flow or other related command or control signals, such as external airflow command Signal 1075. 图8中的命令信号920还被命令到空气流块906,其可以包括图1、图2和图3中的空气流控制器30以及其所控制的回风和送风流(42和52)。 Figure 8 is also a command signal 920 to the air flow command block 906, which may include 1, 2 and 3 of the air flow controller 30, and it controls the return air and feed air flow (42 and 52). 作为替换方案,空气流块906可以是另一控制块,例如图9中的空气处理器调节风门控制器1213以及图6的相关联的调节风门或空气流控制设备1068、1070和1072,其表示用于外部空气1007、排风空气1004、和循环空气1005的关联于空气处理器1000的空气流的控制设备。 As an alternative, the air flow control block 906 may be another block, such as in FIG. 9 air handler damper controller 1213 and FIG. 6 associated damper or air flow control devices 1068,1070 and 1072, which represents 1007 for external air, exhaust air 1004, and 1005 associated with circulating air in the air handler air flow control device 1000. 图8A还描述了块907,其表示环境的稀释特性。 Figure 8A also depicts a block 907, which represents the dilution characteristics of the environment. 对于熟悉控制系统设计领域的技术人员,907表示环境的传输特性,其在此情况下定义了受控环境的空气流等级如何与所感测的空气质量参数908的值有关。 For those familiar with the field of control system design and technical personnel, 907 represents the transmission characteristics of the environment, which defines the level of air flow and the value of the controlled environment of how air quality parameters sensed about the 908 in this case. 在此,可以在图6和图9的输出控制块MOA或外部空气流控制器块1200内,或潜在地或部分地分别在图1、图2、图4、或图6的信号处理控制器块130、 210、530、或1130内,或在建筑物控制系统180内实现误差级902、反作用控制块903、最小ACH箝位904、以及最大ACH箝位905。 Here, the block may be controlled within MOA or external air flow controller block 1200 the output of Figures 6 and 9 in, or are potentially or partially in Figs. 1, 2, 4, or signal processing controller 6 of FIG. the block 130, 210,530, or 1130, or implement error level 180 in the building control system 902, reaction control block 903, the minimum ACH clamp 904, and the maximum ACH clamp 905.

[0132] 可以使用控制系统设计领域技术人员已知的大量控制策略中的任何策略来实现控制块903,并且控制块903作为示例可以包括以下控制的任意组合:比例控制、比例-积分控制、比例-积分-微分控制、前向反馈技术、自适应和预测控制、以及模糊逻辑策略。 [0132] Using the control system designers skilled in the art of a large number of control strategies in any strategy to achieve control block 903, and the control block 903 as an example may include any combination of the following control: proportional control, proportional - integral control, proportional - integral - derivative control, forward feedback technology, adaptive and predictive control, and fuzzy logic strategy. 控制块903的本质要素之一在于,它提供必要的反作用以及电平转换(levelshifting)功能, 从而它可以合适地作用于误差信号914(给出对误差级902示出的减法逻辑),以便创建命令信号920,至少对于传感器反馈908超过空气质量参数设定点901的情况,所述命令信号920可以产生环境的空气流等级的增大。 One of the essential elements of the control block 903 is that it provides the necessary reaction and level translation (levelshifting) function, so that it can be appropriately applied to the error signal 914 (given subtraction logic error level 902 shown), in order to create command signal 920, at least for the sensor feedback 908 exceeds the air quality parameter set point 901, the command signal 920 may be generated ambient air flow level is increased. (作为替换方案,可以改变902的逻辑,从而使908 减去901)。 (As an alternative, the logic 902 can be changed, so that the 908 minus 901). 举例来说,质量参数设定点901可以被设定为1. 5ppm,并且所感测的空气质量参数例如可以是从感测TVOC (例如使用光离子化检测器或PID传感器)和二氧化碳而创建的混合信号。 For example, the quality parameter set point 901 may be set to 1. 5ppm, and the air quality parameter may be sensed for example from the sensing TVOC (e.g. using Photoionization detector or PID sensors) and carbon dioxide created Mixed signals. 控制块903将被配置成使得当传感器反馈908小于设定点901时,903的输出将小于或等于由最小ACH箝位块904所建立的最小箝位值。 Control block 903 will be configured such that when the sensor 908 feedback 901 is less than the setpoint, the output 903 will be less than or equal to the minimum value by the minimum ACH clamp clamping block 904 established. 904是“高-选择(high-select),, 土夬,即它将比较903的输出值与某个最小箝位值(例如4ACH),并将两个值中较大的值呈递给下一个块905。例如,如果903的输出是2ACH,并且904中设定的最小箝位值是4ACH,则904的输出将是4ACH。904的输出被呈递给最大ACH箝位905,其中所述最大ACH箝位905 提供“低-选择(low-select) ”功能,即它将比较904的输出值和规定的“最大箝位”值(例如12ACH),并将这两个值中较小的值输出到空气流块906。系统900的工作方式是:如果所感测到的空气质量参数的水平突然增大(例如由于清洁剂的溢出)到空气质量参数设定点901 (例如设定为1. 5ppm TV0C)之上,则控制块将(在例如设定为12ACH的最大箝位905 的限制内)把命令信号920增大到将受控环境内的TVOC浓度限制到1.5ppm所必需的值。 在实践中,可以将设定点901设定为小于用于要被感测的空气质量参数或混合参数的TLV 的值,以确保所维持的浓度将被限制为安全的稳态值。作为替换方案,空气质量参数设定点901可以具有基于由908监控的空气质量参数的持久性而进行调节的动态值。 904 is a "high - Select (high-select) ,, soil Jue, i.e. it compares the output value 903 and a minimum clamp value (e.g. 4ACH), and the larger value of two values presented to the next block 905. For example, if the output 903 is 2ACH, and the minimum clamp value 904 is set 4ACH, the output of the 904 will be presented to the output 4ACH.904 is maximum ACH clamp 905, wherein said maximum ACH Clamp 905 to provide "low - Select (low-select)" function, that it will "maximum clamping" comparative output value 904 and a predetermined value (for example 12ACH), and the smaller of the two values of the output to air flow block 906. The system 900 works by: if the level of the sensed air quality parameter feeling suddenly increases (e.g., due to overflow of detergent) to the air quality parameter set point 901 (e.g., set to 1. 5ppm ) above TV0C, the control block (e.g., set to a maximum within the limit clamp 12ACH 905) the command signal 920 is increased to the limit TVOC concentration to 1.5ppm controlled environment within the required value. In In practice, the set point 901 may be set to be smaller than the TLV value for the sensed air quality parameter or mixing parameters, in order to ensure that the concentration will be limited to maintain the security of the steady-state value. As an alternative , air quality parameter set point 901 may have a value based on the dynamic persistence 908 monitor air quality parameter and for adjusting.

[0133] 图8B示出提供与图8A相同的控制功能的系统900的可选实施例,但用于任意数量“η”的空气质量参数,其使用各个空气质量参数反馈信号,例如图4的561Α、562Α、534Α、 535Α或536Α的输出,而不是使用混合空气质量参数反馈信号(例如图4的538Α)的图8Α 的方法。 [0133] Figure 8B shows a view similar to providing system control functionality. 8A alternative embodiment 900, but the air quality parameter for any number "η", which uses individual air quality parameter feedback signal, e.g., FIG. 4 Method 561Α, 562Α, 534Α, 535Α or 536Α output, instead of using the mixed air quality parameter feedback signals (e.g. 538Α FIG. 4) of FIG 8Α. 采用本方法,为每一感测的空气质量参数(1至“η”)提供专用误差级902和控制功能块903,其中,信号909所示的第η个感测的空气质量参数的设定点进入误差级910,其中所述误差级910具有输出915,所述输出915由功能块912来处理。 According to the present method, for each sensed air quality parameter (1 to "η") to provide dedicated error stage 902 and control block 903, a setting in which the signal of η a sensed air quality parameter 909 as shown in Enter error level 910, wherein said error stage 910 has an output 915, the output 915 from the function block 912 to process. 来自每一控制块(例如来自控制块903至91¾的输出被呈递给高选择块913,所述高选择块913将各控制项中的最大的一个从控制块传递到空气流块906,作为命令信号920。通过使用该方法,我们可以基于通过使用用于每一受监控的空气质量参数的各个设定点(例如901至909)以及各个感测的空气质量参数反馈信号908或911而从多个空气质量参数(例如TV0C、微粒、以及其它空气质量参数的宿主(host))创建的混合命令信号920,将稀释通风控制提供给环境(例如20)。有效地,图8B允许为每一空气质量参数来个别化各个控制功能块912,在某些情况下这是有利的,因为特定空气质量反馈信号潜在地需要可以基于各个控制环路来最佳处理的不同的控制增益和稳定性设定,而不是使用一个控制环路和增益设定以及混合反馈信号。采用图8的实现,在高选择块913处的控制环路的积分创建混合命令信号920。此夕卜,对于某些情况,块913可以被实现为求和,而不是高选择块,其中,根据需要来比例缩放对块913的输入中的每一个,以允许信号关于彼此被适当地加权以及求和。 From each control block (e.g., from the control block 903 to 91¾ high output is presented to the selection block 913, the high select block 913 will each control item in the largest one transfer from the control block 906 to block air flow, as a command signal 920. By using this method, we can be based on various set points by using for each of the monitored parameters of air quality (e.g., 901-909) and each sensed air quality parameter feedback signals 908 or 911 from the multi- Mixed air quality parameters command signal (e.g. TV0C, particulates, and other air quality parameters of the host (host)) created 920, the dilution ventilation control to the environment (e.g., 20). effectively, allowing for each air Fig. 8B Quality parameters of each individual control function block 912, in some cases it is advantageous because the specific air quality feedback signal potentially require different control gain can be set to the optimum and stability of processing based on various control loop instead of using a control loop and the gain setting and mixed feedback signal. FIG. 8 using realized, in order to create a high mixing block 913 to select the control loop of this integral signal 920. Xi Bu, for some cases, block 913 may be implemented as summation, rather than high selection block, wherein, scaling as needed to the input of block 913 in each of a signal with respect to each other is to allow the appropriately weighted and summed.

[0134] 通过使用图1、图2、图6的系统或网络化的光子采样系统,存在若干有利的控制实现和方法,其可以被实现为解决当尝试创建并使用基于混合或复合的空气质量参数的信号以用于建筑物系统(例如HVAC系统)的监控和控制时出现的问题。 [0134] By using FIG. 1, FIG. 2, FIG system or networked photonic sampling system 6, there are several advantageous realization and control methods, which can be created and used to achieve when attempting to solve the hybrid or composite air quality problem when the signal parameters to monitor and control systems for buildings (eg HVAC systems) arise. 这些信号的一个应用是在控制进入建筑物的外部空气时,或相似地控制被提供进入空间的稀释通风或外部空气的量。 An application of these control signals are in the outside air entering the building, or similar control is supplied into the space of dilution ventilation or outside air quantity. 例如,被引入建筑物的外部空气可能变得被一种或多种空气污染物轻微污染或严重污染。 For example, the outside air is introduced into the building may be by one or more air pollutants slightly polluted or heavily polluted. 这样的污染物可以包括来自汽车或卡车排气装置或来自熔炉或锅炉排风装置的再次飞散的一氧化碳、高水平的室外微粒、可能从附近的排风烟囱(exhaust stack)再次飞散的TV0C、或其它室外空气污染物源。 Such contaminants may include carbon monoxide from scattering again car or truck exhaust or exhaust from furnace or boiler means, a high level of outdoor particles, may exhaust from nearby chimney (exhaust stack) scattering again TV0C, or Other outdoor air pollutant sources. 如果这些空气污染物没有被滤清并且进入到正被馈送入房间的送风空气中,则可能触发稀释通风控制,以不适当地增大来自外部空气入口的外部空气流和/或送风空气流。 If these are not Filtration and air pollutants being fed into the air supply into the room air, it may trigger dilution ventilation control to unduly increase the flow of outside air from the outside air inlet and / or blowing air stream. 相似地,送风空气污染物的增多可能没有高得足以通过其本身来触发增大的送风空气流或外部空气流命令,而是被加到房间或建筑物中的现有空气污染物水平中,这可能使系统对发源于房间或建筑物内的低的或中等的空气污染物水平过度敏感。 Similarly, an increase in blowing air pollutants may not be high enough by itself to trigger the increase of blowing air or outside air flow command, but is added to the existing air contaminant levels in the room or building , which may make the system for low or moderate levels of air pollutants originated within a room or building overly sensitive. 由于增大包含空气污染物的送风或外部空气的控制操作仅增大了房间或建筑物内的特定的空气污染物的水平,因此这两个问题都可能潜在地产生失控的结果。 Due to the increase of air pollutant control operations include air or outside air only increases the level of air pollutants particular room or building, so these two issues could potentially produce results runaway. 这可能驱使送风空气流或外部空气流水平甚至更高,直到无论是使用两状态、三状态、还是VAV方法,如果外部空气或送风系统污染物足够高,则进入房间的送风空气流或进入建筑物的外部空气流将最终被命令到其最大值。 This may drive the blower air flow or even higher level of outside air flow until either the use of two state, three state, or VAV method, or if the external air supply system contamination is high enough, the room air into the air flow or outside air flow entering the building will eventually be a command to its maximum. 由于送风系统空气流潜在地馈送多个房间,因此潜在地所有这些房间将被推到其最大流,或者被抽入建筑物中的外部空气的量可能潜在地达到100%之多的外部空气。 Since the amount of air supply system feeding the air stream potentially multiple rooms, thus potentially all of these rooms will be pushed to their maximum flow, or is drawn into the external air in buildings could potentially reach as much as 100% of the outside air . 这会导致超过送风系统的空气流容量和/或加热和制冷容量,其潜在的结果是进入房间空间的流减少,并且如果由于过量外部空气被吸入建筑物而导致被调节的送风空气的温度不能被合适地控制,则这可能导致这些空间的温度控制的潜在损失。 This causes the air flow capacity than the air supply system and / or heating and cooling capacity, the potential result is to reduce the flow into the room space, and if the outside air is sucked in due to excessive building caused by the blowing of air is adjusted Temperature can not be properly controlled, this can result in a potential loss of control of the temperature of these spaces.

[0135] 作为替换方案,在使用回风的建筑物中(例如以图6中的空气处理单元100来实现和示出的系统),可能会将一个空间中的高水平的污染物通过回风及其后的送风空气而循环进入其它空间。 [0135] As an alternative, the use of the return air in the building (e.g., in Figure 6 to achieve the air handling unit 100 and the system shown), may interpret a high level of contaminants in the space through the air return after blowing air and is circulated into the other space. 在这种情况下的正确行动不应是增大各个房间中的房间送风空气,而是反之适当地增大外部空气,以稀释包括作为污染物源的空间的整个建筑物。 In this case the corrective action should be increased in each room of the room air blower, but on the contrary suitably increased outside air, including as a contaminant source at a dilution space entire building.

[0136] 解决这些问题的一种示例性控制方法是使用差分测量技术。 [0136] An exemplary control method for solving these problems is to use a differential measurement technique. 在该方法中,从房间空气测量中减去外部空气或送风空气测量,以创建感兴趣的各种空气污染物对外部空气或送风空气的差分测量。 In this method, subtracting the measured outside air or blowing air from the room air measurements, in order to create a variety of air pollutants of interest differential measurement of the outside air or blowing air. 因此,如果外部空气或送风空气的微粒、CO、TVOC等增多,则由于将减去送风源的效果,因此将仅对于房间中的空气污染物源来评估房间空气的空气质量。 Therefore, if the outside air or blowing air particles, CO, TVOC, etc. increases, the effect due to the air source is subtracted, so the only source for the room air pollutants in the air of the room to assess the air quality. 有效地,由于如果送风空气或外部空气是空气污染物源,则增多送风空气或外部空气将不会使房间更干净,因此我们在此不关注房间空气的绝对空气质量,而是仅关注空气质量是否由于房间或空间中的源而恶化。 Effectively, due to air or outside air if the air is a source of air pollutants, the increase in air or outside air will not make the room air cleaner, so we are not concerned in this room air absolute air quality, but the only concern Air quality is due to the room or space in the source and worse.

[0137] 例如,如前文所述,我们首先开始于使用例如图1和图2中的房间采样位置23A、 回风管道采样位置43A、和/或房间传感器27A进行例如空间20A中的空气的空气污染物测量。 [0137] For example, as previously described, we first start using e.g., Figs. 1 and 2 in a room sampling position 23A, the return air duct sampling location 43A, and / or room sensor 27A 20A performed, for example air space air pollutant measurements. 作为替换方案,如图6所示,还可以使用建筑物水平测量(例如被选择为感测空气污染物对温度的回风管道传感器1021、和/或来自空气处理单元1000的回风管道空气采样位置1031)。 As an alternative, as shown in Figure 6, you can also use the building level measurements (for example, choose to sense the temperature of air pollutants on the return air duct sensor 1021 and / or 1000 of the return air duct from the air handling unit air sampling position 1031). 在该示例性方法中,接下来基于下述情况来进行空气污染物的基准测量:1)外部空气使用例如图1或图2中的空气采样位置63、或图6中的空气采样位置1033 ;或2)送风空气使用例如图1或图2中的送风管道空气采样位置53B,或图6中的空气处理器1000 送风管道空气采样位置1037。 In this exemplary method, based on the following conditions for the next reference measurement of air pollutants: 1) the use of outside air such as in Figure 1 or Figure 2 air sampling location 63, or Fig. 6 air sampling location 1033; or 2) an air blower for example Figure 1 or Figure 2 of the air duct air sampling location 53B, or FIG. 6 air handler supply duct air sampling location 1000 1037. 测量外部空气或测量送风空气的要被感测的具体位置基于感兴趣的空气处理系统和参数而改变。 Measuring the external air or blowing air to the specific measurement position is sensed based air handling system and the parameters of interest change. 例如,如果空间正在直接从室外接收100%外部空气,而没有回风空气,则来自图1的外部空气管道60之内、或来自图6的外部空气管道采样位置1033的送风空气或外部空气的测量将至少对于气体或VOC测量提供精确的结果。 For example, if the space is receiving 100% outside air directly from the outside, but no return air, the outside air from the duct 60 of FIG. 1, or from the outside air duct sampling location in Fig. 6 blowing air or outside air 1033 Measurement of VOC gas or at least to provide accurate measurement results. 然而,当至少微粒测量是所感测的感兴趣的空气污染物时,重要的是,要在从空气处理单元的所有风机系统和所有空气过滤器下游的位置(例如在上述送风管道采样位置1037或53B) 进行空气污染物的基准测量。 However, the measurement is of interest when at least the particles sensed air pollutants, it is important that all the fan from the system to the air handling unit and all the air filter downstream of the location (e.g., in the above-mentioned air duct sampling location 1037 or 53B) benchmark measurement of air pollutants. 这种需求是由于送风处理单元过滤器(例如图6中的预过滤器1016和过滤器1008)改变直接外部空气测量和其中一个过滤器之后的送风空气之间的微粒读数所造成的影响而导致的。 This demand is due to the impact of particle readings blowing air blower filter processing unit (e.g., FIG. 6 of the pre-filter 1016 and filter 1008) to change the direct measurement of the outside air and one after the filter caused between caused. 因此,由于后者的情况和这些原因,应该从外部空气测量直接采取基准测量。 Thus, due to the latter case and for these reasons, a reference measurement should be taken directly from the outside air measurement.

[0138] 此外,如果来自其它区域的回风与外部空气混合以产生送风空气,如图6中的空气处理单元1000示出,则至少对于外部空气和回风空气变得充分混合之后的位置,使用下游送风管道空气流基准测量而不是直接外部空气基准测量作为对空间或区域污染物测量的基准也是必要的。 Position [0138] In addition, if the return air and the outside air from other areas are combined to produce blowing air, as shown in the air handling unit 1000 is shown, at least for the outside air and return air becomes sufficient after mixing , using the air duct downstream of the air flow baseline measurement rather than a direct reference measured outside air as a reference measurement of the spatial region or contaminants are also necessary. 由于外部空气和回风空气的混合将潜在地产生送风管道中与外部直接可见的污染物水平不同水平的污染物,因此对于涉及回风系统甚至气体的任何空气污染物测量都是如此的情况。 Due to the outside air and return air mix will potentially generate air ducts and external direct visible contaminant levels at different levels of pollutants, so the return air system involving the measurement of gas or air pollutants are so any situation . 由于从同一空气系统流入这些空间的所有送风空气应该具有相似的特性和空气污染物值,因此对于从单个空气处理器或主送风管道馈送的所有空间,仅使用一个送风或外部空气管道测量应该就足够了。 All of these blowing air flowing into the space from the same air system should have similar characteristics and values of air pollutants, so for all of the space from a single processor or a main air supply duct feeding, using only one supply or outside air duct measurements should be sufficient.

[0139] 另一方面,如果使用建筑物送风空气或建筑物回风空气的空气污染物测量来帮助控制被引入建筑物的外部空气的量,则应该从外部空气测量而不是从送风空气测量来获取合适的基准测量。 [0139] On the other hand, if the use of the building or building air blowing air pollutants return air measurement is introduced to help control the amount of outside air of the building, should be measured from the outside air instead of blowing air from measurements to obtain the appropriate reference measurement.

[0140] 此示例性方法中的下一步骤涉及取每一对空气污染物测量(空间或建筑物空气、 和外部空气或送风空气),以及通过以下方式将它们转换为一组差分测量:从空间空气污染物测量减去基准外部空气污染物测量或送风空气污染物测量,如果更方便反过来进行操作,则也可以反过来进行操作。 [0140] The exemplary method of the next step involves taking each pair of measuring air pollutants (space or building air, and outside air or blowing air), and by the following manner to convert them to a set of differential measurements: measurements of air pollutants from the space outside air pollutants minus baseline measurements or measuring air pollutants, in turn, if more convenient to operate, you can also turn to operate. 执行该操作的实施例的示例是图5的减法块37,其中,例如TVOC的送风或外部空气测量将施加到减法块的负(-)输入端,TVOC的空间或回风管道空气污染物测量则将被施加到正(+)输入端。 Example embodiments of the implementation of this operation is subtraction block 37 of FIG. 5, which, for example, the air or outside air TVOC measurements will be applied to the subtraction block negative (-) input, TVOC space or return air duct of air pollutants measurement will be applied to the positive (+) input terminal. 其后,输出将是该空间的TVOC的差分测量。 Subsequently, the output will be a differential measurement of the space TVOC. 本领域技术人员将知道减去这些空气污染物测量的其它方法,例如在计算机化的控制系统中的软件变量、或者其它实施方式。 Those skilled in the art will know other methods subtracting these measurements of air pollutants, such as in a computerized control system software variable, or other embodiments.

[0141] 于是将以前述对于非差分房间空气测量的相同方式来处理单个的差分空气污染物测量,并且因而将例如被单独使用或组合,然后由图1、图2、图4、或图6的信号处理控制器块130、210、530、或1130分别比较和分析,以创建空气质量参数反馈信号538或1075,其中所述信号538或1075例如可以由输出命令块MOA或外部空气流控制器1200分别进一步作用,以产生用于改变进入空间20的送风空气流的命令信号31、以及用于进入建筑物的外部空气流的命令信号1075。 [0141] For the same manner as in the foregoing will so non-differential room air processing of a single measurement of the differential measurement of air pollutants, and thus for example be used alone or in combination, and then by the FIG. 1, FIG. 2, FIG. 4, or Fig 6 The signal processing controller blocks 130,210,530, or 1130, respectively, compared and analyzed, in order to create an air quality parameter feedback signals 538 or 1075, or 1075 wherein the signal 538 may be composed of output command block MOA or outside air flow controller 1200, respectively, and further action, to generate a command signal for changing the blowing of air into the space 20 of the stream 31, and a command signal 1075 is used to enter the building outside air stream.

[0142] 由于可以在合理短的时间段内(例如5到30分钟)用同一传感器来执行送风空气或外部空气的测量以及空间空气测量,因此对于所述差分测量控制构思,图1、图2或图6 的共享传感器多点空气采样系统实施例是优选实施例。 [0142] since it is possible in a reasonably short period of time (e.g., 5-30 minutes) by the same sensor to perform blowing air or outside air measurements and measurements of air space, so for control of the differential measurement concept, Fig. 1, Fig. 2 or FIG. 6 shared sensor multipoint air sampling system embodiment is a preferred embodiment. 结果,由于当相减这两个测量时抵消了很多传感器误差,因此消除了这些传感器误差。 As a result, because when the subtraction of these two measurement offset many sensor error, thus eliminating the errors of these sensors. 因此,即使在与外部空气或送风空气污染物的潜在高的源水平相比,房间中的很重要的空气污染物的增大非常少时,也可以进行十分精确的差分测量。 Thus, even in comparison with the outside air or potential source of high levels of air pollutants in the air, the room is very important to increase air pollutants is very low, it can be very accurate differential measurements. 结果,这些高的室外或送风背景水平实质上没有降低环境空间内的任何污染物源的测量的分辨率和精度。 As a result, these high outdoor air or background level is substantially not reduced resolution and accuracy of the measurement of any contaminant source ambient environment.

[0143] 可以用于图1、图2或图6的实现的另一优选控制方法与可能出现高水平的送风或外部空气污染物的情况有关,但上述差分房间空气信号指示在空间中不存在实质的空气污染物源。 [0143] Figure 1 can be used, another preferred control for the Figure 2 or Figure 6 may be the case with a high level of air or outside air pollutants concerned, but the difference signal indicates that the room air in the space is not the existence of a substantial source of air pollutants. 在此情况下,空间中的空气污染物的绝对水平可以高得足以触发增大的稀释水平, 但差分信号正确地指示增大送风不合适。 In this case, the space in the absolute level of air pollutants may be high enough to trigger an increased level of dilution, but the differential signal correctly indicates an increase in air inappropriate. 在此情况下,由于空气污染源是送风空气,因此有利的是,减小经由送风控制设备51的送风空气和/或通过外部空气控制调节风门1067的外部空气,直到外部或源空气包含较低水平的空气污染物。 In this case, due to air pollution is blowing air, is therefore advantageous to reduce the air control device 51 via the blowing air and / or control to the outside air through the outside air damper 1067, or until the external air source comprises lower levels of air pollutants.

[0144] 这种控制方法的一个实施例包括如上所述在送风管道50B、外部进风口管道60、 或空气处理器外部空气管道采样位置1033进行一个或多个空气污染物测量。 An Example [0144] This control method described above comprises one or more air pollutants measured in air duct 50B, the external air inlet duct 60, the outside air or air duct sampling location processor 1033. 于是,所述一个或多个空气污染物测量可以被组合或单独使用,其后分别由图1、图2、图4、或图6的信号处理控制器块130、210、530、或1130进行比较和分析,以确定这些信号是否超过合适的触发水平(例如用于环境空间20的水平)。 Thus, the measurement of one or more air pollutants may be used alone or in combination, respectively, by the subsequent Figures 1, 2, 4, or Fig 6, the signal processing controller block 130,210,530, or 1130 were Comparison and analysis, to determine whether the trigger signal exceeds the appropriate level (e.g., level 20 for the environment space). 如果满足了这些触发水平或合适的触发条件,则可以由若干种方法中的一种来使用块130、210、或1130,以减小送风和/或外部空气流。 If the trigger level or those suitable trigger conditions, it is possible by a number of methods used in one block 130,210, or 1130, in order to reduce the supply and / or outside air flow. 例如,为了减小房间送风流,可以通过从信号处理控制器块130或210输出的命令来完全不考虑并且有效禁用温度控制块90的图3中的温度控制输出93,从而送风流将变得仅由将被减小到低水平的稀释通风命令31所命令的流来控制。 For example, in order to reduce airflow delivery room, by the signal processing controller block 130 or 210 outputs the command with no regard to the temperature control and effectively disable block 90 in FIG. 3 temperature control output 93, which will be sent to Merry only by dilution ventilation will be reduced to a low level command stream 31 commands to control. 例如,为了减小建筑物外部空气流, 可以由信号处理器控制器1130来将空气处理器单元1000的外部空气调节风门1067命令到与用于以节能装置(economizer)来进行自由制冷的潜在地更高流等级相比的更低流等级,所述更低流等级表示用于占用的最小所需流等级。 For example, in order to reduce the flow of air outside the building, by the signal processor controller 1130 can be a processor unit the air of the outside air damper 1000 and 1067 is used to command to the power saving device (economizer) for free cooling of potentially higher compared to the lower level of the stream flow levels, the lower flow level indicates the minimum required flow for occupancy levels.

[0145] 可以在本发明中执行的一个特别有用的混合空气质量参数测量涉及焓测量。 [0145] A particularly useful mixed air quality parameter measurements can be performed in the present invention relates to enthalpy measurements. 参照该方法,湿度计是用于进行水分测量的设备,并且典型地提供电压、电流、或数字输出,所述输出表示被采样的空气或其他气体的水分含量。 Referring to this method, the hygrometer is used for moisture measurement apparatus, and will typically provide voltage, current, or digital output, the output represents the moisture content of the sampled air or other gases. 湿度计所进行的基本测量典型地是露点(或冷凝)温度,或者可以通过浓度来呈现,例如百万分之几-ppm、或千分之几-ppt、或一些其它合适的单位的系统。 Basic measurement hygrometer performed typically dew point (or condensing) temperatures, or may be presented by the concentration, e.g., parts per million -ppm, or a few thousandths -ppt, or some other suitable unit system. 此外,对于可商业上获得的湿度计十分平常的是计算其它干湿特性,所述干湿特性可能需要同时测量所感测的气体的第二属性(例如温度),以便获得期望的特性(例如焓和相对湿度)以及其它特性。 In addition, for the hygrometer can be obtained commercially very common is to calculate other wet and dry properties, the wet and dry properties may need to measure the properties of the sensed second gas (e.g. temperature), so as to obtain the desired properties (e.g., enthalpy and relative humidity), and other features. 此外,如果已知绝对压力,则可以将湿度计的水分测量用于推导湿度比率,某些可商业上获得的湿度计也提供上述功能。 In addition, if the absolute pressure is known, it can be used to derive a hygrometer to measure humidity, moisture ratio, hygrometer can get some of these features are also available commercially. 为了本发明的目的,湿度计可以基于熟悉水分测量领域的技术人员所知的各种技术中的任何技术。 For purposes of the present invention, any technique can hygrometer familiar moisture measurement based on various technologies known to a person skilled in the art of. 这些技术包括但不限于:冷镜湿度计(chilled mirror hygrometer)、基于红外线的水分分析仪、声表面波(SAW)技术、氧化铝传感器、以及将RH感测设备与温度传感器组合以从所感测的空气或被感测的其它气体推导出露点温度、水分浓度、或水分含量的其它合适的测量。 These techniques include, but are not limited to: chilled mirror hygrometer (chilled mirror hygrometer), infrared moisture analyzer based on surface acoustic wave (SAW) technology, aluminum oxide sensors, and the RH sensing device in combination with the sensor from the sensed temperature air or other gas sensed deduced other suitable measuring dew point temperature, water concentration, or moisture content. 例如,这些类型的仪器中的一些的源例如包括可以由Marlborough,MA的Edgetech Moisure and Humidity Systems提供的冷镜湿度计、或者基于红外线的水分分析仪,例如可以从LICOR Biosciences 公司获得的LICOR 840 单元。 For example, the source of these cold mirror in some types of instruments include, for example may be provided by Marlborough, MA's Edgetech Moisure and Humidity Systems hygrometer, or LICOR 840 units based on infrared moisture analyzer, such as available from LICOR Biosciences Corporation .

[0146] 当由这样的湿度计设备来测量所推导的干湿特性(例如焓、RH、以及其它依赖于温度或压力的特性)时,所推导出的参数(RH、焓等)的精度高度依赖于由设备同时进行的温度或压力的本地测量的精度。 [0146] When the device by such a hygrometer to measure the wet and dry properties are derived (e.g., enthalpy, RH, and the other depends on the temperature or pressure characteristics), the derived parameters (RH, enthalpy, etc.) the accuracy of the height depends on the accuracy of local measurements performed simultaneously by a device temperature or pressure. 因此,当将这些湿度计设备应用于多点采样系统时,例如由于采样的位置和共享传感器位置220之间的温度差,多数所推导出的干湿特性(例如RH和焓)将实际上随着空气采样从采样位置被传输到多点采样系统的共享传感器位置220(图2)而被改变,因此仅可以使用基本露点温度或其所提供的水分浓度测量。 Therefore, when these hygrometer equipment used in multi-sampling systems, such as the temperature of the sample due to the location and position of the sensor 220 share difference between wet and dry most of the derived properties (such as RH and enthalpy) will actually follow the air sampling position is transferred from the sampling location to a shared multi-point sampling system sensor 220 (FIG. 2) is changed, and therefore can only be measured using the moisture concentration substantially the dew point temperature or they provide.

[0147] 还可以从本领域公知的干湿表来推导焓或其它干湿特性信号的公式。 [0147] can also be known from the art to derive formulas psychrometer wet enthalpy or other characteristics of the signal. 作为示例, 美国专利第4,672,560号公开了一种示例性焓计算器,通过引用而将该专利的全部内容并入到本文中。 As an example, U.S. Patent No. 4,672,560 discloses an exemplary enthalpy calculator, by reference the entire contents of which patents are incorporated herein.

[0148] 从露点温度和周围温度计算RH的一种常用方法例如涉及Clausius-Clapeyron方程的解释,该方程用于在下面的式(1)中所阐述的蒸气压力: [0148] A common method of calculating RH from dew point temperature and ambient temperature, for example concerning the interpretation Clausius-Clapeyron equation, the equation used to (1) set forth in the following equation vapor pressure:

[0149]式 1 [0149] Formula 1

[0150] 其中,E =蒸气压力,ES =饱和蒸气压力,TA =周围温度,单位是开尔文,TD =饱和或露点温度,单位是开尔文。 [0150] where, E = vapor pressure, ES = saturation vapor pressure, TA = ambient temperature in Kelvin, TD = saturation or dew point temperature in Kelvin. 此外,如对干湿测量领域熟悉的技术人员所知道的,存在多种其它近似,当温度和露点温度已知时,这些近似可以用于计算蒸气压力和饱和蒸气压力, 从所述蒸气压力和饱和蒸气压力中,可以计算RH和其它干湿特性,例如焓。 In addition, as the measurement of wet and dry areas of the art are familiar known, there are a variety of other approximation, when the temperature and dew point temperature are known, these can be used to calculate the approximate vapor pressure and the saturated vapor pressure, the vapor pressure and from saturated vapor pressure can be calculated RH and other wet and dry properties, e.g. enthalpy.

[0151] 通过检查式(1)可以看出,相对湿度不仅取决于露点温度TD,而且还取决于周围温度TA。 [0151] By examining the formula (1) can be seen, not only depends on the relative humidity of dew point temperature TD, but also on the ambient temperature TA. 例如通过使用该式我们可以看出,(例如)对于给定露点温度51华氏度,如果由 E.g., by using this formula we can see, (e.g.) the dew point temperature for a given 51 ° F, if the

38空气采样系统从处于70华氏度的位置取空气采样,并且在传输到包含湿度计的共享传感器220(图2、的过程中,采样的温度增大到75华氏度,则该采样的RH将从大约51% RH改变到大约43% RH,当进行这样的测量时,上述情况是举足轻重的。当进行其它干湿特性的远程测量时存在相似的问题。 38 air sampling system to take air samples from a position at 70 degrees Fahrenheit, and is transferred to a shared hygrometer sensor 220 (FIG. 2, in the process, the sample temperature is increased to 75 degrees Fahrenheit, the sample will RH change from about 51% RH to about 43% RH, when performing such measurements, the above situation is important. A similar problem exists when the remote measurement of other wet and dry characteristics.

[0152] 在本发明的一个方面中,多点空气采样系统包括湿度计,其被包括作为公共传感器组中的其共享传感器220(图幻中的一个,其中所述传感器的用于每个采样位置(例如20A、20B和20C)的水分测量与从每一采样空间进行的本地温度测量(例如25A)进行组合, 以生成信号(例如连接到BAS的181,或信号571A),其表示依赖温度的干湿特性,例如每一采样空间20A、20B、20C的焓或相对湿度。 [0152] In one aspect of the present invention, a multi-point air sampling system includes a hygrometer, which are included as a common sensor group which shared sensors 220 (FIG magic one, wherein said sensor is used for each sample position (e.g., 20A, 20B and 20C) of the moisture measurement and the local temperature measurement (e.g., 25A) from each sample space are combined, to generate a signal (e.g., 181 is connected to the BAS, or signal 571A), which represents the temperature dependence The wet and dry properties, e.g., each sample space 20A, 20B, 20C, or enthalpy relative humidity.

[0153] 多点空气采样系统可以包括传感器组中的湿度计,其可以被用于与所感测的位置的本地离散温度传感器甚至和压力传感器组合,以确定所感测的位置的绝对湿度和温度两者,从而计算混合空气质量参数信号,该信号表示相对湿度、焓、湿度比率、以及其它干湿特性。 [0153] Multipoint air sampling system may include a sensor group hygrometer, which can be used with the measured position of the sensed local discrete temperature sensor and a pressure sensor even in combination, to determine the measured absolute position of the sensed humidity and temperature for two persons, thereby calculating the mixed air quality parameter signal that indicates a relative humidity, enthalpy, humidity ratio, and other wet and dry properties. 当应用于RH感测时,这种布置的一个重要的优点在于,与使用倾向于随时间而明显漂移的分布式RH传感器的常规系统相比,这种布置提供了相当可观的改善。 When applied to the measured RH sense, an important advantage of this arrangement is that, compared with conventional systems tend to drift significantly over time distributed RH sensor, this arrangement provides a considerable improvement. 当在用于建筑物通风系统的管道系统或通风间内进行RH测量时,尤其如此。 When RH measurements in between piping system or ventilation for building ventilation systems, in particular. 例如,如果湿度计被并入到共享传感器220(图2),则位于管道50B中的输出温度传感器27B(图2、可以与从所感测的位置5¾获得的水分测量组合,以便提供来自管道50B的对RH的高度精确且漂移稳定的测量,以及其他依赖于温度的干湿特性。这与可商业获得的管道安装的RH传感器相比具有很大的优势,至少由于当被放置在空气流中时与这些传感器对微粒物质的暴露有关的捕获(fowl ing)而导致这些传感器不可靠。此外,这些离散传感器倾向于由于传感器元件的成本以及所需的电源和机械外壳而导致价格昂贵。 For example, if the hygrometer is incorporated into a shared sensor 220 (FIG. 2), are located in the duct 50B output temperature sensor 27B (FIG. 2, may be obtained from a combination of moisture measurement sensed position 5¾, so as to provide from conduit 50B RH on the highly accurate and stable measurement drift, and other characteristics dependent on the temperature of the wet and dry. This is commercially available pipe installed RH sensor has a great advantage as compared to at least due when placed in an air stream When these sensors related to exposure to particulate matter captured (fowl ing) which causes these sensors unreliable. In addition, these sensors tend discrete sensor elements due to the cost and the required power and resulting mechanical enclosure expensive.

[0154] 相似地,可以根据本发明的教导来进行高精度和稳定的焓测量,其与进行这种测量的常规装置相比提供了实质的改进。 [0154] Similarly, high accuracy and stability can be measured according to the teachings of the present invention, the enthalpy, which is the conventional means to perform such measurement offers substantial improvements compared. 这对于与外部空气的控制(例如节能装置应用)有关的应用、以及其它空气处理器控制应用是尤其重要的。 This outside air control (e.g., power saving device applications) the application, as well as other air handler control applications are particularly important.

[0155] 图9示出这些混合焓测量加上用于外部空气控制目的的其它混合空气质量参数测量的创建和使用的示例,其中图9示出用于来自图6的外部空气流控制器块1200的逻辑和功能的一种潜在实现。 [0155] Figure 9 shows an external air flow controller block enthalpy of mixing of these measurements together with the outside air is used to create the sample other mixing air quality parameter measurements and the use of a control purposes, in which FIG. 9 shows a from Figure 6 a potential to achieve 1200 logic and functionality. 在该图中,由回风焓块1205通过使用上述干湿关系以及回风空气露点或绝对湿度1201加上回风空气温度1202的空气质量参数测量中的一些来执行回风空气1001的焓计算。 In the figure, the return air enthalpy block 1205 using the above relations, and return air dry and wet air dew point or absolute humidity of 1201 plus the return air temperature of the air quality parameter measurements of some 1202 to 1001 perform return air enthalpy calculation . 这些测量分别从采样位置1031和管道传感器1021取得,并由来自图6 的信号处理控制器块1130来处理。 These measurements are sampled from the position sensor 1031 and the pipe 1021 made by the signal processing controller block 1130 in Figure 6 to process from. 相似地,由外部空气焓块10¾通过使用外部空气露点或绝对湿度信号1203以及外部空气温度信号1204来进行外部空气焓测量。 Similarly, by the outside air enthalpy block 10¾ by using outside air dew point or absolute humidity signal 1203 and 1204 outside air temperature signal to the outside air enthalpy measurement. 这些测量分别从空气采样位置1033和管道传感器1023取得。 These measurements were obtained from the 1023 and 1033 air sampling pipe sensor location. 由减法块1207使块1025和10¾输出的两个焓信号彼此相减,如所示的那样,或者从外部空气焓信号减去回风空气焓。 By subtracting block 1025 and 1207 so that the two block signals 10¾ enthalpy output subtracted from each other, as shown above, or minus return air from the enthalpy of the outside air enthalpy signal. 得到的差分焓信号用于节能装置控制器1208,其是可商业获得的,并且为空气领域技术人员所知,当与对回风制冷相比引入更多外部空气则成本会更低时,它可以生成外部空气流命令,以便引入更多外部空气。 Enthalpy difference signal obtained for energy saving device controller 1208, which is commercially available, and known to those skilled air, when compared with the return air cooling of the outside air is introduced into the additional cost will be lower when it outside air flow can be generated commands to bring in more outside air. 可商业获得的节能装置控制器的一个制造商是Honeywell。 A manufacturer saving device controller is commercially available Honeywell.

[0156] 于是可以由功能块1209对来自节能装置控制器1208的自由制冷外部空气流命令进一步进行比例缩放和偏置,然后,由低选择比较器或强制覆盖块1210对其进行作用。 [0156] Thus can be further scaled and offset by the function block 1209 pairs 1208 Freedom cooling outside air flow control commands from the energy-saving devices, and then select the low comparator or enforce its role in covering the 1210 block. 这个块的目的在于,当外部空气被污染到的水平使得如果可能的话最好不要增大外部空气时,强制覆盖并降低来自节能装置1208的自由制冷外部空气命令。 The purpose of this block, when the external air is polluted to a level such that, if possible, it is best not to increase the outside air is forced to cover and reduce freedom of saving a command from the external air cooling apparatus 1208. 为了实现该功能,可以进行外部空气污染物测量并组合该测量,并由低选择比较器来使用。 To achieve this, the outside air pollutants can be measured and the combination of the measurement by the low select comparator to use. 例如以室外空气质量参数信号1221、1223和1225来示出该操作,空气质量参数信号1221、1223和1225分别表示微粒、一氧化碳、TVOC的室外水平。 For example, outdoor air quality parameter signals 1221,1223 and 1225 to illustrate the operation of the air quality parameter signals 1221,1223 and 1225 respectively, particulates, carbon monoxide, TVOC outdoor levels. 其后,将这些信号与它们各自的阈值信号或设定点1220、1222和12¾进行比较。 Thereafter, these signals with their respective threshold signal or setpoint 1220, 1222 and 12¾ comparison. 比较器1231、1233和1235分别比较这些室外空气污染物信号,并基于所述阈值与空气质量参数信号的差,在两状态、多状态、或连续可变方式中产生变高的输出信号。 Comparators 1231,1233 and 1235 respectively compare the outdoor air pollutants signal, and the difference between the threshold air quality parameter signal based on, in the two-state, multi-state, or a continuously variable manner to produce an output signal goes high. 其后,将这些比较后的信号提供给功能块1232、1234、和1236,所述功能块1232、1234、和1236可以对这些信号进行比例缩放和偏置或应用任何其它适当的处理, 从而它们可以被低选择比较器1210使用,以完全或部分强制覆盖(override)节能装置的经过比例缩放的输出。 Then, after comparison of these signals is supplied to the function blocks 1232,1234, and 1236, the function blocks 1232,1234, and 1236 of these signals can be any other suitable processing or scaling and bias application, so that they You can choose to be relatively low 1210 used in full or partial mandatory coverage (override) after saving device scaling output. 同等地,室外空气质量参数信号可以被组合和混合为混合室外空气质量参数信号,并且可以使用一个比较器来创建强制覆盖信号。 Equally, the outdoor air quality parameter signals may be combined and mixed for mixing outdoor air quality parameter signal, and a comparator can be used to create a forced override signal. 否则,低选择比较器1210 组合并使用各个信号。 Otherwise, the low select comparator 1210 and uses a combination of the respective signals. 然后,比较器块1201的输出由另一功能块来比例缩放或修改,从而它可以处于与其他信号相同的比例、或适合于以其他信号一起来进行高选择,其中所述其它信号表示基于C02测量而对建筑物中的占用的量进行供给所需的外部空气的量,以及合适地稀释在建筑物中偶然生成的任何空气污染物的足够外部空气。 Then, the output of the comparator block 1201 by another function block scaling or modified so that it can be in the same proportion with other signals, or other signals adapted to select a high together, wherein the other signal representation based on C02 measurement of the amount of occupancy of the building will be the amount of external air required to supply, as well as adequate outside air is suitably diluted accidentally generated in the building of any air pollutant.

[0157] 创建这种基于组合的稀释和占用情况的外部空气命令信号开始于来自信号处理控制器1130的空气质量参数测量,这种测量可以基于解复用的共享传感器测量或本地传感器读数。 [0157] combinations that are based on the outside air dilution and occupancy start command signal to the air quality parameter measurements from the signal processing controller 1130, this measurement may be based on a shared sensor demultiplexed measurement or local sensor readings. 例如,附图示出使用来自两个房间20A和20B的测量、以及用于每个房间的两个空气质量参数测量的潜在设置,所述两个空气质量参数测量即C02和TVOC,C02用于确定占用情况的外部空气量需求,TVOC表示空气污染物测量,以确定稀释这些空气污染物所需的外部空气的量。 For example, the drawings show the use of the potential provided from two rooms 20A and 20B of the measurement, and the two air quality parameter measurements for each room of said two air quality parameter measurements i.e. C02 and TVOC, C02 for determine the occupancy of the outside air traffic demand, TVOC, said air pollutants measured to determine the amount of dilution air pollutants required external air these. 作为替换方案,可以使用其它空气污染物,以及可以使用多种空气污染物来创建混合空气污染物信号。 As an alternative, you can use other air pollutants, and can use a variety of air pollutants to create a mixed signal of air pollutants. 此外,如上所述,优选地,使用空气污染物对合适的基准的差分测量。 In addition, as described above, preferably, a differential measurement of the air pollutants suitable reference. 当使用房间空气测量用于控制进入建筑物的外部空气时,合适的基准是外部空气测量。 When a measurement is used to control the room air into the outside air of the building, the outside air is a suitable reference measurement. 因此,通过减法块1237从房间20A TVOC信号1227减去室外TVOC信号1225。 Thus, by subtracting block 1237 minus 1225 outdoor TVOC signal from room 20A TVOC signal 1227. 相似地, 通过减法块1239从房间20B TVOC信号12¾减去外部TVOC基准1225。 Similarly, subtract 1225 from external TVOC reference room 20B TVOC signal 12¾ by subtraction block 1239. 如前文所述,任何这些减法或用于C02的减法可以被反过来执行,即从一个信号中间去另一个信号,或者从该另一个信号中间去该一个信号。 As mentioned above, any of these subtractor or subtraction for C02 can be executed in turn, i.e. to the middle of a signal from another signal, or to which a signal from the further intermediate signal. 这些差分测量产生房间20A的差分空气污染物信号1241 和来自房间20B的1M3,由比例缩放和偏置块1245和1247分别对其进一步处理。 These differential measurements generated air pollutants room 20A of the differential signal 20B in 1241 and from the room 1M3, by scaling and offset blocks 1245 and 1247, respectively, for its further processing. 典型地, 对这些房间或为空气污染物测量或C02占用测量而选择的其它房间进行选择,因为它们被看作“风险区域”,其具有高占用情况或高水平的空气污染物的潜在可能。 Typically, these rooms or other rooms or C02 occupancy measurements measure selected for air pollutants selected because they are considered "risk zone", which has the potential for high levels of high occupancy or air pollutants.

[0158] 对于关于外部空气的占用需求的信息,C02被用作测量占用情况和传送到空间的外部空气的量的装置,如前文所述。 [0158] For the outside air on the occupancy demand information, C02 is used as a measure occupancy and transferred to the outside air means the amount of space, as previously described. 为了执行合适的测量,由于对空间中的C02的绝对水平的差是占用情况所直接基于的,因此还期望C02的差分测量。 In order to perform proper measurement, due to the space C02 is the difference between the absolute level of occupancy of the direct-based, it is also desirable C02 differential measurements. 因此,在减法块1238中从房间20AC02信号12¾减去室外空气C02信号1226,以生成差分C02信号1M2,其被比例缩放块1246进行比例缩放和偏置。 Therefore, the subtracting block 1238 subtracts signal 1226 from the outside air C02 room 20AC02 signal 12¾, C02 to generate a differential signal 1M2, scaling block 1246 which is to be scaled and offset ratio. 相似地,在减法块1240中从房间20B C02信号1230减去外部空气C02信号1226,以生成差分C02信号1M4,其被比例缩放块1248进行比例缩放和偏置。 Similarly, block 1240 is subtracted in the subtracter outside air C02 signal 1226 signal 1230 from the room 20B C02, C02 to generate a differential signal 1M4, scaled block 1248 which is scaled and offset. 现在可以基于期望的控制需求以多种方式来组合或混合各个比例缩放之后的差分空气污染物信号。 Now the demand differential air pollutant control signal may be based on a desired combination or in various ways after mixing the respective scaling. 例如,可以对这些信号进行高选择,这是优选的,或可以将它们加在一起。 For example, these signals can be high selectivity, which is preferred, or they can be added together. 以房间20B示出一个示例,其中,由混合功能块1249来组合差分C02和TVOC信号,以生成用于该房间的一个混合空气质量参数信号。 To room 20B shows an example in which, by the function block 1249 to combine the mixed C02 and TVOC differential signal to generate a mixed air quality parameter signal that room. 房间20A的信号被示出是单独使用的,但其后在特殊功能控制1250中与来自房间20B的混合信号一起被高选择或组合。 Room signal 20A is shown alone is used, but then the special function control 1250 20B mixed with a signal from the room along with a high selectivity or a combination thereof. 特殊功能控制1250的输出是流命令信号,其对于修改后的自由制冷信号被高选择,以生成用于外部空气的最终命令信号1075。 Special Function Control 1250 is a streaming command output signal, which is highly selective for the modified free-cooling signals to generate a final order for the external air signal 1075. 此外,空气处理器调节风门控制器块1213可以用于创建实际调节风门控制信号1068、1070和1072,它们分别与外部空气、排风空气、和循环空气对应,用于空气处理器1000,其潜在地使用来自外部空气流测量信号1080的外部空气流量的反馈。 In addition, air handler damper controller block 1213 may be used to create the actual damper control signals 1068,1070, and 1072, respectively, and the outside air, exhaust air, and the corresponding circulating air for air handler 1000, its potential using feedback from the external air flow measurement signal 1080 external air flow.
