摘　　要：针对供水管道泄漏检测与定位问题,提出了基于多传感器的泄漏微弱信号检测及漏点定位方法,与传统的检测方法相比,该方法可以提高检测定位的精度。设计了以STC89C52为核心的信号检测及提取装置,该装置可检测管道泄漏情况,并通过USB接口与上位机通信,进而实现对泄漏点进行定位分析,满足了对信号处理与分析的灵活性要求。In order to solve the problems of the leakage detection of water supply pipeline and the location of leakage, the methods for the detection of the weak leakage signal and the localization of the leakage based on multi-sensor were presented. Com- pared with the traditional detection methods,this method can improve the detection accuracy. Using STC89C52 as the core, the sig- nal detection and extraction device was designed and can be used to detect the leakage conditions of the pipeline. Through USB in- terface communicating with the host computer, the positioning analysis of the leakage points was realized,thus meeting the flexible requirements for the processing and analysis of the signal.
