基于GSM/GPRS的城域化管网泄漏监测与定位系统

针对城市供水管网的地下破裂和泄漏,设计了基于GSM/GPRS通信的远程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GPRS网络实现远程数据传输;系统基于GIS技术构建,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,可及时、准确的发现和定位泄漏点.该系统运用GPRS网络实现了低成本、高效率的城域化、网络化的管网泄漏检测,为城市供水管网的应急抢险提供了一个良好的平台,在实际使用中取得良好的效果.

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

On the underground booster and leakage of the city water network pipe,a remote leakage monitoring and locating system based on GSM/GPRS is developed .The parameters of tap water pipe network ,i.e., flow, velocity, direction and pressure are collected by monitor terminal ,the data transmission is realized by GSM/GPRS network .Aiming at the feature of the underground booster and leakage of the water pipe, with the GIS technology and the signal processing methods ,such as negative P wave and flow detecting, accurate and prompt positioning of leakage location can be detected. The system can not only realize the leakage detection of low cost, city area, networking by GPRS network but also provide a emergency platform of tap water pipe network .The system has been used in practical tap water pipe network with excellent results.
