基于GSM/GPRS的供水管网泄漏监测与定位系统

GSM/GPRS Based Leakage Monitoring and Locating System of Tap Water Pipe Network

介绍了一种基于GSM/GPRS网络的供水管网泄漏监测与定位系统,由管网监测终端实时采集管网流量、流速、流向和压力,通过GSM/GPRS网络实现远程数据传输,利用基于GIS的Web技术实施城域化、网络化、信息化的管网状态监管。针对供水管网突发性的爆管和地下泄漏特点,综合运用了负压波和流量检测法进行泄漏模式识别与漏点定位,能够及时、准确的发现和定位泄漏点,并在实际使用中取得良好的效果。

A GSM/GPRS based leakage monitoring and locating system of tap water pipe network is introduced. The parameters of tap water pipe network, i.e. flow, flow velocity, flow direction and pressure are collected by monitoring 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. With the pattern recognition and position detecting methods, such as negative P wave and flow detecting, a booster leakage or a underground leakage of the water pipe can be detected timely and the leakage location can be found accurately. The system has been used in practical tap water pipe network with excellent results.
