摘　　要：为了实现沪久550mm热连轧生产线过程控制系统和人机交互界面的动态数据交互,设计并开发了过程机与WinCC监控系统之间的通讯软件。该通讯软件的数据接口采用双层结构,内层基于OPC协议,使用多线程技术在人机界面端建立了OPC服务器进行数据读写;外层基于TCP/IP协议与过程机建立SOCK-ET通讯,建立了线程互斥机制,实现了并行处理的效果。实际应用表明,该软件完全满足了现场过程控制系统和人机交互界面间动态数据交互的需求且运行稳定。Communication interface software for WinCC monitoring system and process computer was designed and developed independently in order to realize dynamic data exchange between process control system and hu- man machine interface of the Hujiu 550ram strip line. The communication software data interface used double layer structure. The internal layer of interface was followed the OPC technology specification with multi-thread technology. The outer layer was based on the TCP/IP protocol to communicate with process computer. A new parallel thread structure was projected and it can achieve real effect of parallel processing. The practical pro- duction show that it can completely satisfied the requirement of dynamic data exchange between process control system and human machine inter{ace on site.
