Leakage monitoring and locating method of water supply pipe network

To solve the monitoring and locating problems of the underground booster and leakage of the supply water network, a remote leakage monitoring and locating system based on GSM/GPRS is designed. The parameters of water supply pipe network, i.e., flow, flow velocity, flow direction and pressure are collected by monitor terminal. The data transmission is realized by GSM/GPRS network and the status of tap water pipe network is monitored by the GIS based Web software. Based on the feature of the underground booster and leakage of the water pipe, negative P wave and flow detecting methods is used based on the pattern recognition. Practice shows the system can detect leakage of the water pipe timely and found the leakage location accurately. At present, it has been used in practical tap water pipe network with excellent results, and it is valuable for generalization and application.
