摘要/Abstract

摘要： 对监控系统技术改造过程中出现的信号误报警、调度通信系统数据通信异常、101规约通信数据刷新慢及AGC/AVC工作站死机4个典型故障进行分析,发现上述问题分别由回路电磁干扰、程序存在bug、流程考虑不周全、固件版本落后及负荷分配计算程序不合理引起。通过下列处理方法故障全部得到解决:加强回路抗干扰能力及在程序中对信号进行滤波,剔除程序bug、合理安排进程启停时间及顺序,优化程序流程及策略以减少发送的数据量、缩短发送队列的长度,升级固件版本、优化负荷分配计算程序以防止AGC/AVC工作站死机。结果表明所采用处理方法是有效的。

Abstract: In the process of technical renovation for the monitoring and control system, there are four typical faults: false alarm signals, abnormal data communication in dispatch communication system, slow data refreshing of the 101 communication protocol and AGC/AVC workstation crash. Through analysis, we found that these faults are caused by circuit electromagnetic interference, software bugs, ill-considered procedures, outdated firmware version and unreasonable allocation in calculation procedures, respectively. We can solve all the faults by strengthening circuit anti-interference ability and filtering signals in the program, removing program bugs , reasonably arranging the start-stop time and orders in processing sequence, optimizing process and strategies to reduce the amount of data sent and shorten the queues length, upgrading the firmware version, and optimizing the load distribution of calculation program to avoid halt of AGC/AVC workstation system. Results show that the measures are effective.
