摘要
基于COM/DCOM技术的OPC是工业控制界流行的软件互操作标准。文中介绍了OPC技术,提出了实现INFI-90数据开放的基本软件构架。INFI-90为系统的数据开放提供了多种接入方式,文中分析并比较了INFI-90系统与外部系统通信的几种方式。在此基础上,将OPC技术与INFI-90系统提供的实时数据开放接口相结合,开发了INFI-90实时数据OPC服务器,实现了INFI-90实时数据的真正开放与共享。
OPC based on COM/DCOM technology is a popular co-operating standard for industrial software. This paper describes the OPC technology and puts forward a basic software framework to make the INFI-90 system's real-time data open, and compares several communication ways of access to data open of the INFI-90 system with external systems. Finally, hy combining the OPC technology with the INFI-90 system' s data open interface, the INFI-90 real-time data OPC server is developed, by which the INFI-90 system's real-time data can be genuinely opened and shared.
