模式识别在输水管网明漏与暗漏检测中的应用

输水管网的明漏和地下水管的暗漏是供水系统的重要研究问题,挖掘输水管网明漏和暗漏的漏损模式,对于保障供水系统的正常运转有着重要意义。文章基于整体-局部的思想,首先针对明漏问题构建端到端的失水率模型,以5%作为警戒阈值,刻画失水率分析图;其次引入皮尔逊系数对端与邻端做相关性检测,建立地下水管暗漏的检测预警模型,结合实际数据进行检测和定位。实验结果表明,该模式能有效、快速的检测漏损情况。

The open leakage of the water pipe network and the concealed leakage of the underground water pipe are two important research issues of the water supply system. Excavating the leakage pattern of the open leakage and the dark leakage of the water delivery pipe network is of great significance for ensuring the normal operation of the water supply system. Based on the whole-local idea, this paper constructs the end-to-end water loss rate model for the open leakage problem, and takes 5% as the warning threshold to depict the water loss rate analysis chart;secondly, Pearson coefficient is introduced to detect the correlation between the end and the front. The detection and early warning model of underground water pipe leakage is established, and the detection and location are combined with the actual data. The experimental results show that this mode can detect leakage effectively and quickly.
