一种供水管道泄漏检测及定位的新方法

针对目前供水管道泄漏检测及定位系统准确性和灵敏度较低的现状,通过采集供水管道泄漏时的多种特征信号,采用最优加权融合算法,将多传感器信息进行综合处理,扩展了时间和空间上的检测范围,提高了泄漏检测系统的灵敏度和可靠性。利用供水实验系统进行了模拟实验,实验结果验证了信息融合检漏方法比单一检漏方法具有明显的优越性。

A new method for water supply pipeline leakage detection and localization

At present, the sensitivity and reliability of the water supply pipeline leakage detection and localization system remain low. The characteristic signals of pipeline leakage are dealt with by using the adaptive weighted fusion estimating method. This method can extend the monitoring range for the time domain and the space domain. And it can raise the sensitivity and reliability of the leakase detection system. We have experimented on the water circulation system which are composed of the water pump and the stainless steel pipeline in laboratory. Compared with the mere use of leakage detection, information fusion technology has remarkable superiority.
