供水管网流量数据统计分析用于漏损定位研究

Leakage Location through Flow Data of Water Supply Network

漏损问题是当今社会的热点问题,为了使漏损定位更加快速、科学,对供水管网流量数据进行了统计分析。通过供水管网中的流量监测点,能够得到大量的流量数据,以此为基础,分别研究了 t检验分析法和均值差分析法应用在漏损定位中的可行性与准确性,并对这两种方法进行从无漏点到单漏点、从无漏点到多漏点、从少漏点到多漏点、等多种情况的比较分析,为水司进行供水管网漏损管理提供新思路。结果表明,两种方法均能较为准确地定位漏损,其中均值差分析定位漏损时干扰较少,t检验分析则能够充分利用每个数据。

The leakage problem of water supply network is hot in modem society. In order to locate leakage more quickly and scientifically, the flow data of water supply network were analyzed. A large amount of flow data can be obtained through the flow monitoring points in water supply network. On this basis, the application of mean difference test and student' s t test in leakage location was introduced, and the two methods were compared from no leakage to single leakage, no leakage to multiple leakages, and few leakages to multiple leakages. The results showed that both methods could locate the leakage accurately, and the mean difference test had less interference when locating the leakage. The student's t test could make full use of each data.
