The Design Of Intelligent Uptown Monitor System

In order to construct low-priced,reliable intelligent network in the uptown,to meet the demands of safety and information management in the intelligent uptown,I studied the fieldbus technology.Base on our contry condition of intelligent building system and development tendency in the future,I made a suggestion on technical precept of High Speed Ethernet and designed an Intelligent Uptown monitor system.Monitor system Configurable platform adopts Configurable software of King Word ,and system control network adopts HSE(High Speed Ethernet) which is easy to commune together with business Ethernet .In the design of device driver open OPC standard interface technology is adopted which reduces the time of developing device driver, implements pluging and playing between study and software and is convenient for devices to updating.For expansion connectors are left in advance new functions can be added to according to the practical demand of different clients.The main content of this article is made up of six sections. Section 1 studies some basic problems of intelligent Uptown, introduces the method of intelligent Uptown system analysis, the noteworthy principles in the design of intelligent Uptown ,and the problems exist in the design of intelligent Uptown currently . Section 2 and section 3 analyse field-bus and HSE and introduce development of control system, features of field-bus, development current status and trend of field-bus. The two sections also analyses the problems exist in the real time of industry Ethernet, introduces the features of OPC interface technology, analyses the communication model structure of HSE,and introduces the topology structure and fault tolerance handling . Section 4 introduces the design of monitor system such as safekeeping of Uptown, alarm of fire, automatic charging of car park and three-meter receiving. Section 5 introduces the application of OPC in the monitor system .This section introduces in detail the hierarchical structure, the design and implementation method of OPC data service server and the method of reading and writing data to field-device. Finally in the appendix the method of system configuration is introduced.
