Description
The application requires in the interests of the U.S. Provisional Application sequence number 60/085,539 of proposition on May 15th, 1998, the whole open reference as this paper of this application.
The a part of this disclosure content comprises the copyright that the applicant requires.The applicant does not oppose to duplicate these contents in the process of copy application documents or any the application's of issue patent, but keeps all other rights of these content of copyright.
Relate generally to of the present invention utilizes the control of the OO Control Software of modularization and monitors the system and method for various systems, described Control Software with the local controller related with controlled system in operation and utilize communication network such as the Internet centralizedly to its control, supervision and renewal.These system and methods are particularly useful in brick pattern automatic system (BAS) application.
Past is such as the control system of the brick pattern automatic system proprietary solution of single tame manufacturer or autonomous system complicated integrated typically.Industrially be devoted to formulate standard, but also do not had real unified approach so that can more effectively integrated such system.
The BACnet/LonMark that is used for the brick pattern automatic system
TMThe issue of fieldbus (fieldbus) communication standard causes the thinking again to brick pattern automatic system architecture, and this may thoroughly change the controlling schemes prospect.Traditional special-purpose brick pattern automatization system arrangement works is good, but they in design and install be expensive, on reconfiguring be trouble and need a large amount of software usually for the facility of integrated independent utility is professional.On the contrary, under distributed BACnet/LonMark fieldbus architecture, logical process is encapsulated in autonomous many producers module, and these modules communicate with one another to coordinate to solve brick pattern control problem by standard software.Yet, in known brick pattern automatization system structure, before BAS can control new parts effectively, must be input to the external interface feature of adding the parts in the control system in the database of the external interface feature of representing parts.
But but the distributed control expection under this mode can make the minimized optimal control software of installation wiring, reduce operation/maintenance cost and simplified system expansion.Under the global competition environment of current market, the user needs the flexible, reusable of fieldbus and drops into effective brick pattern control solution so that respond variation in the facilities management business fast.
Yet the progress in the brick pattern automated system has taken place not to be applied in a satisfactory manner as yet in other calculating field.For example, the various computer system standards of the cost and the development requires of the system of streamlining procedures have been developed.Major technology comprises OO software, is Java
TMVirtual machine (JVM) and JavaBeans
TM
Object oriented programming provides a kind of new method of more directly with the software brick pattern entity of real world being carried out modeling, compares it with conventional programming mechanism and mates with real world better.Influence hardware design and functional same way as with microprocessor, this new software normal form influences software field day by day.
In Object oriented programming, create application program from building block module (object) independently.The invention wheel is different again during with each creation new procedures, the application module that the Application Engineer finishes writing before can taking from the storehouse and insert them simply.By using library of object, the developer is devoted to suitable object connected together and write their required any customized objects of application.Customized objects can and then be added re-using after being provided with in the storehouse to.
The networking standard is also developed in the process of the cost of being devoted to simplify the system integration and development requires.The major technique of developing in the brick pattern robotization industry comprises the assembling and the Control Network (BACnet of U.S. heating, refrigeration and air-conditioning man SCTE (ASHRAE)
TM) and ECHELON LONTALK
TMAgreement (by the Echelon company of California Palo Alto) exploitation.
Simultaneously in computer industry, also be devoted to develop communication standard, although these standards are not applied in the specific question of brick pattern robotization with any real effective and efficient manner once more as yet.For example, the purpose of the Internet/www/Java/CORBA standard provides the information that the user wants, and do not consider to use any class method, what operation or the form of information be on which type of machine.
By the hypertext system, the user of Web can select and watch the information from all over the world.But, Web lack real interactivity-promptly lack user and use between real-time, dynamic and visual mutual.Java has brought this interactivity that lacks to Web.By the Web browser that allows Java, the user can run into animation and interactive application.
Because contracted affreightment send temporal changeability and the Internet to lack guaranteed transmission, all be unsuccessful usually in the effort that realizes real-time control system on the Internet.
Conclusion is, control system is mainly based on the proprietary technology of single producer in history.Although made an effort these structures of standardization, only obtained limited success.The inventor need to be sure of a high comprehensive standard in the control system field, this standard is integrated be specially adapted to the brick pattern automation application based on the Common Object Model of Java and utilize communication network standards that centralized control and supervision are provided such as the internet.
