摘要
模拟屏控制系统是调度自动化的重要人机接口,为解决实时数据服务器与分布式模拟屏之间一对多的不匹配通信问题,研制了一种多线程通信服务器。利用Java多线程和RMI远程调用的分布式技术,从硬件接口、通信规约、软件编码与工程应用等方面,进行了关键通信服务过程的交互控制设计实现和运行测试研究。该多线程通信服务器已作为分布式模拟屏控制系统的核心模块,在铁路电力调度中心牵引供电远动系统工程中投入了实际应用,在工程现场取得了良好的效果。
Mimic screen control system is an important human-machine interface of automation system.In order to solve mismatch communications between real-time data and distribution mimic screen,multi-thread communication server was developed.Interaction implementation of key communication service processes was designed in terms of hardware interfaces,communication protocol,software code and engineering application.Test was carried out based on java multi-threads and remote method invocation.This multi-thread communication server has been used in distribution mimic screen control system as a core module,and good results are achieved in tele-control engineering application of railway power dispatch center.
