中文摘要: 介绍了数据采集与监视控制系统中遥测误差产生的原因,以及检测遥测数据误差的方法.运用T-SQL语言中的查询指令对数据库中凌晨3时至4时的数据进行查询运算,可有效避免电容器组带来的误差影响,准确判断出遥测数据中的不正常信息,且计算速度快、工作量小.
Abstract:The causes of errors of the telemetry SCADA system is described and some data error detection methods are described.By applying the T-SQL query language commands in the database, the query expression is applied at 3 to 4 o’clock data points,which can effectively avoid the error caused by capacitor effect and estimate the abnormal information.Morever,the method also has characteristics of high calculation speed and small workload.
