摘　　要：针对供水管网的终端泄漏检测问题,基于三端型线性霍尔敏感元件UGN3501T和嵌入式ARM处理器S3C2410A设计了泄漏自动检测和报警控制仪,将泄漏检测报警、自动关断支网水源和用水量计量等功能集为一体,能很好地解决因下游阀门未关而造成的泄漏问题。测试分析表明,新型检测仪的平均泄漏检测率高达98%,设计方案科学可行,应用前景广阔。In order to solve the shortcomings of the leak detection for water supply network, a novel detection system was designed based on UGN3501T and embedded ARM chip of S3C2410A. The detection system has the advantages of leak detection, automatic alarm, water metering and so on. Experimental results show that the success rate of detection as high as 98%, the design decision is feasible and the application is broad.
