摘要
为了能够及时发现长距离输水管线泄漏等的异常状况,需要对其压力流量的监测数据进行处理分析。本文提出运用方差检验法来判断压力流量等监测数据平稳状况,结合压力流量的平稳状况来判断管线是否运行正常。结果表明:运用方差检验法可以准确判断压力或流量的监测数据是否平稳;结合压力、流量的方差检验结果可以准确判断管线是否运行正常。此方法运用简单,有助于及时发现威胁管线安全的因素。
The monitoring data of pressure flow capacity should be processed and analyzed in order to discover the abnormalities of long-distance water pipeline. In the paper, it is proposed that the variance test method can be applied for judging the stable condition of pressure flow capacity and other monitoring data. The stable condition of pressure flow capacity can be combined for judging whether the pipelines are operated normally or not. Results show that the variance test method can be applied for accurately judging whether the monitoring data of the pressure or flow capability is stable or not. Pressure and flow capacity variance test results are combined for accurately judging whether the pipelines are operated normally or not. The method is applied simply, which is beneficial for discovering factors threatening pipeline safety timely.
