摘　　要：提出了一种对输油管道泄漏检测信号的统计处理方法。实际应用表明 ,该方法可以有效地滤除粗大误差、累进性系统误差和周期性系统误差 ,为管道监测部分提供了可靠的数据 。This article introduces a statistic processing method for automatically detected signal of pipe laying leakage. The practical application indicates that this method can effectively filtertip the bulky errors, progressive system errors and periodic system errors. It can also provide reliable data for the pipe supervising and reduce the rate of erroneous warning greatly.
