基于OPEN-3000系统前置网络问题的排查与处理

Investigation and Handling of Front-end Network Problems Based on OPEN-3000 System

摘要:

前置系统作为调度自动化系统的组成部分，对于实现主站端与厂站端之间实时数据通信处理具有重要意义。文中研究了一起调度自动化前置系统单平面厂站104通道全部退出故障处理案例。通过前置通道分析对比、网络拓扑结构测试、关键设备软硬件排查等多种技术手段，最终定位到故障点并解决了问题。首先，提出系统前置服务器程序的逻辑判断存在家族性缺陷；然后，针对性地给出了处理方案，对于其他公司自动化专业人员进行前置服务器故障处理具有借鉴意义。

Abstract:

The front-end system, as an essential part of dispatching automation system, plays an important role in data transmission between master station and substation. A fault handling case is investigated when all 104 channels of single plane plant station exit in dispatching automation front-end system. Through channel comparative analysis, network topology structure test, software and hardware troubleshooting of key equipment and other technical means, the fault point is located and the problem is solved eventually. It is the first time to propose the familial defect in logic judgment program of front-end server, and its targeted treatment plan is given, which can provide a reference for automation professionals in other companies when dealing with the front-end server failure.
