摘　　要：电力二次系统的通道接入调试和通道运行状况诊断一直是调度自动化建设和运行过程中非常重要的工作环节。通过查看通道报文来调试和诊断通道运行状况则是远动运行维护中频繁使用的一项手段。这些工作之前必须是在安全I区完成。本文设计并实现了一种在安全III区通过浏览器订阅并查看分析前置报文的方法。该方法通过网络中间件穿越物理隔离装置,利用高速缓存实现三区准实时前置报文浏览,实现了跨电力安全区的前置报文查看,大大提高了通道调试的效率和方便性。The debugging and diagnosis of channel accession in power secondary system have bean an important part for power dispatching automation.Through view messages to debug and diagnose channel health is a commone method of remote operation and maintenance.In the past,this work must be done in the safety zone I.This paper designed and implemented a method for subscribing to and analyzing the front end messages through the browser in the security zone III.The method cross through the physical isolation device through the network middleware,and the quasi-real-time front-end message browsing by using the cache was implemented.The efficiency and convenience of Front End channel debugging were greatly improved.
