煤矿监控系统产生伪数据的原因和应对措施

摘要

针对煤矿监控系统普遍存在的伪数据问题,通过实地调查、现场测试和分析研究,总结了煤矿监控系统产生伪数据的主要原因,指出巷道中电力电缆的浪涌干扰是产生伪数据最主要的原因;提出了去除伪数据的主要技术措施、抗电力电缆浪涌干扰的具体措施及由分站软件通过识别数据变化速率滤除伪数据的方法.%In view of problem of false data existed in coal mine monitoring and control system,the paper summed up main causes of false data of coal mine monitoring and control system through field investigation,testing and analyzing,pointed out surge interference of power cable in roadway is the most main cause.It put forward main technical measures to remove the false data,concrete measures of antiinterference measures for power cable surge,and proposed method of using substation software to filter false data by identifying change rate of data.
