电力线连网装置和方法 Powerline networking device and method

技术领域 Technical Field

一般地,本发明涉及电力线连网技术领域,进一步说,本发明涉及计算机电源线和计算机数据通信接口之间的信号接口。 Generally, the present invention relates to the field of power line networking technology, and further, the present invention relates to a signal interface between a computer power cord and computer data communications interfaces.

背景技术 Background

电力线技术(PLT)已经并将继续被快速引入消费市场,以支持家庭连网和其他本地网络情况。 Power line technology (PLT) has been and continues to be the rapid introduction of the consumer market to support home networking and other local network conditions. 例如,可以利用家中的电力线路以不同于电力传输频率的频率载送数据通信信号,把家中的多台计算机连到一起。 For example, you can use home power lines different from the frequency of the power transmission frequencies carrying data communication signals, around the house multiple computers connected together. 而且可以把其他的数据处理设备用类似的方式在家中连网。 And you can put other data processing devices in a similar fashion home networking. 例如,可以用电力线技术把家中的应用设备以及家庭通信设备连在一起,如电话、视频设备、家庭安全设备、监视设备等。 For example, even with a power line technology in applications around the house and home communications equipment together, such as telephones, video equipment, home security equipment, surveillance equipment.

通常,个人计算机(PC)不需要优化来支持PLT。 Typically, a personal computer (PC) does not require optimization to support PLT. 目前,附加PLT系统的基本体系或者是内部PC卡(如ISA或PCI),用户将其安装在已有计算机上,或者是具有USB口的外部独立盒或与PC接口的并行电缆。 Currently, the basic system of additional PLT systems or internal PC card (such as ISA or PCI), the user has to install it on a computer, or a parallel cable box has an external USB port independently or with PC interface. PLT模块,无论是内部的还是外部的,必须以某种方式耦合到电力线。 PLT modules, whether internal or external, must be coupled to the power line in some way. 通常PLT模块是通过将信号耦合模块插入到个人计算机附近的空电源插座中来耦合到电力线的。 Typically PLT module by coupling the signal modules are plugged into a personal computer nearby empty power outlet to be coupled to the power line. 为了实现这种耦合,需要有空的电源插座,这在个人计算机系统附近是少见的,因为通常有显示器、打印机和其他附件连接到电源板。 In order to achieve this coupling requires free outlet, which in the vicinity of the personal computer system are rare, because usually there are monitors, printers and other accessories connected to the power supply board. 在有空插座的情况下,用户被迫将PLT模块连到相当嘈杂的电源节点,其中PC是直接连到该电源节点的,而没有通过适当的滤波。 In the case of free outlet, the user is forced to quite noisy PLT module connected to the power supply node, wherein the PC is directly connected to the power supply node, without passing through an appropriate filter. 将PLT模块连接到嘈杂的电源节点会影响PLT网络的运行和性能,这取决于PC及其相连附件所用的电源类型。 The PLT module is connected to a noisy power supply node can affect the operation and performance of PLT networks, depending on the type of power source and connected to PC accessory used.

在使用电源板(power strip)的情况下,现有的电源板可能包含能有效地从电力线解耦高频信号的滤波器。 In the case of using a power strip (power strip), the existing power board may contain high-frequency signal can be effectively decoupled from the power line filter. 因此,为了优化性能将PLT适配器连接到电源板不一定恰当,因为电源板可能滤去的一些高频信号可能是正常的PLT家庭连网通信所需要的。 Therefore, in order to optimize the performance of the PLT adapter to the power board is not necessarily appropriate, because some high-frequency signal may be filtered power board may be normal PLT home networking communication needs. 即使电源板不含滤波器,由于PC电源及其所有连到电源板的外设表现出来的过度噪声和低阻抗,将PLT模块耦合到附近的电源板或插座也是不合适的。 Even if the power board without filters, since PC power supply and all peripherals connected to a power strip manifested excessive noise and low impedance, the PLT module is coupled to a power strip or outlet nearby inappropriate.

在典型的PLT连网接口中,变压器接口用于将高频数据载波信号耦合到电力线。 In a typical PLT networking interface, resolver interface for high frequency data carrier signal is coupled to the power line. 变压器的初级线圈通过耦合电容器连到电力线的交流(AC)插座。 The primary winding of the transformer is connected via the coupling capacitor to the power line of the alternating (AC) outlet. 变压器的次级线圈连到PC或PLT模块内部的数据载波信号驱动器/接收器。 The secondary winding of the transformer is connected to the PC or PLT module internal data carrier signal driver / receiver. 变压器将PC系统与电力线隔离,同时滤去交流电信号成分。 PC system with the power transformer line isolation, while filtered AC signal component. 而且,变压器是通过物理连接器而不是PC电力电缆耦合到电力线,以避免由PC开关电源造成的任何干扰。 Also, the transformer is coupled through a physical connection instead of PC power cables to the power line, in order to avoid any interference caused by a switching power supply PC.

现有的耦合技术通常是最基本的,因为当PC已经通过PC电源线连接到电力线时需要在PC上设有外部端口以支持数据载波信号到电力线的连接。 Existing coupling technology is often essential, because when the PC is connected to the power line through the PC power cord required external ports on the PC has to support data carrier signal to the power cable. 而且,需要从PC到交流电源插座的机内的互连模块以提供必要的耦合功能。 Moreover, the need to interconnect module from PC AC power socket inside the machine to provide the necessary coupling function. 这样,PLT连网设备的主要花费在于到已连接有PC的电力线网络的冗余连接。 Thus, the main cost PLT networked device that is connected to a PC with redundant power line network.

参考图1,描述现有技术的个人计算机(PC)10。 Referring to Figure 1, the prior art describes a personal computer (PC) 10. 在其他硬件中PC 10还包括PC电源15。 In other hardware in PC 10 also includes a PC power supply 15. PC电源15通常包括含有交流插头25的电源线20,用于耦合到传统的电源插座。 PC power supply 15 typically include those containing AC plug 25 of the power line 20, for coupling to a conventional power outlet. 在实施例中,交流插头25可以是但不限于J-类型插头。 In an embodiment, the AC plug 25 may be, but is not limited to, J- type plug. 在典型实现中,电磁干扰(EMI)过滤器25被耦合在电源线20和PC电源15间。 In a typical implementation, electromagnetic interference (EMI) filter 25 is coupled between the power supply line 20 and PC 15. 现有的EMI过滤器25包括在交流插头25的火线(H)和中性线(N)端间耦合的电容器30。 Existing EMI filter 25 is included in the AC plug FireWire 25 (H) and the neutral line between (N) terminal coupling capacitor 30. 变压器35在H和N端耦合并耦合到分别在H端和地间以及N端和地间耦合的电容器40和45。 Transformer 35 H and N terminal coupled and coupled to each terminal and ground between the H and the N-terminus and coupled between the capacitors 40 and 45. 电力线EMI过滤器25一般存在于很多开关电源中。 EMI power line filters 25 are generally present in a lot of switching power supplies. 变压器35通常用与电源端50和55串联的两个共模扼流圈(同向螺旋)电感器实现。 Transformers and power supply terminal 35 is usually 50, and two common mode choke 55 in series (co-helix) inductor to achieve. 两个电感器以常用的螺旋方式缠绕,目的是通过从电力线解耦高频噪声(电感器通常对高频表现出高阻抗)来抑制内部电源电路的EMI发射。 Two spiral inductors in the usual way wound object is achieved by decoupling high-frequency noise from the power line (high frequency inductor usually exhibit high impedance) to suppress internal power supply circuit of EMI emission. 在传统的实现中,这种电感器的值是毫亨(mH)级的。 In conventional implementations, this is the value of the inductor mH (mH) level. 在传统的实现中,可以将数量级为0.1微法(μF)的电容器30加在或不加在H和N之间以进一步解耦通过PC电源线注入到电源的噪音。 In traditional implementations, you can be of the order of 0.1 microfarad (μF) capacitor 30 is applied or not applied between the H and N is injected into the further decoupling PC power supply through power line noise.

因此,PLT连网设备需要将PC内的信号驱动器/接收器不通过外部端口、电力/信号线和/或互连模块耦合到电力线。 Therefore, PLT networking equipment needs to signal drive in PC / receiver is not external ports, power / signal lines and / or interconnect module coupled to the power line through. 而且,为改型现有PC,还对PLT适配器有另一需要,该适配器具有PLT模拟前端(AFE)卡、包括数字信号输入、电力线输入和耦合到PC电源的电源输出。 Moreover, in order to retrofit an existing PC, also have another need PLT adapter, the adapter has a PLT analog front end (AFE) cards, including digital signal input coupled to the input power lines PC power supply output. 而且还需要被优化用于PLT家庭连网的电源板。 But also it needs to be optimized for the PLT home networking power strip. 电源板包括内嵌到具有PLT耦合器的电源板的电源滤波器。 Power board includes embedded PLT coupler having the power board power supply filter.
