摘　　要：当今工业生产中,为了保证控制系统中各种设备充分挥作用以实现控制系统整体的协调有效运行,系统集成越来越受到人们的视。OPC技术把对象链接和嵌入技术应用于工业过程控制领域,为工业控制网络的集成创造了条件。OPC规范主要基于COM心COM的分布式组件技术。通过深入研究O规范和COM技术,对几种网络集成技术的比较研究,论文实现了控制网络的横向和纵向集成,解决了网络传输确定性问题。通过采用交换式以太网技术,提高了系统的实性、网络平台的开放性和可扩展性。模块化设计的方法为其它类型的OPC服务器的开发提供了一种通用性依据。In order to achieve the coordination of the system,the equipments must be used fully,so the system integration attracted more attention.Object Link and Embed technology were applied to industry process control by the technology of OPC,which created conditions for integration of industry control system.OPC was mainly developed based on COM/DCOM technology.Firstly,a composite industry control system that was based on OPC was set up by occupational OPC criterion and COM.The landscape and portrait integration were realized,and the question of veracity in net transmission was resolved.The real-time,openness and expansibility of the system were improved by adopting Switched Ethernet.
