基于OPC技术的分布式监控系统研究

Research of Distributed Monitoring and Control System Based on the OPC

该文在构建了一种基于OPC技术的分布式监控系统体系结构基础上,探讨了OPC服务器和客户端的实现技术,提出了在客户浏览器和内部服务器之间增加一个XML数据发布层———OPCXMLServer的设计思想。OPCXMLServer采用OPC、Java和XML技术编程向浏览器端提供监控画面结构和实时数据,从而实现Internet/Intranet网络异构环境中对各种仪器仪表的远程测量及数据共享。

On the basis of OPC Technology,this paper designs a new architecture of distributed control system and dis-cusses the implementation of OPC Sever and Client.It also gives a concept of OPC XML Server,which is added be-tween client and server.Adopted OPC,Java and XML technology,OPC XML Server sends supervision and control picture and real-time data to clients' browsers.Therefore,remote measurement of instrumentation and data sharing are implement-ed in heterogeneous systems on internet/intranet.
