摘　　要：Since the leakage signals have some characteristics such as low amplitude and wide dynamic range,it is difficult to catch these signals in the real industrial applications. In this paper,a leakage signal acquisition system,which has some unique characteristics such as low noise,low power consumption and easy to be adjusted according to the practical settings,is analyzed and designed. Based on the SCM,this system is capable for signal acquisition and data communication with DSP. It could satisfy the requirements of leak detection and data acquisition in outdoor long-distance operation mode.针对供水管道泄漏信号幅度低、动态范围大的特点,设计了管道泄漏信号采集系统。该系统具有低噪声、低功耗特性,而且采集参数动态可调。系统实现以单片机为核心,完成了数据采集并实现与DSP的数据通信,能够满足户外长距离管道泄漏信号数据采集的要求。Since the leakage signals have some characteristics such as low amplitude and wide dynamic range, it is difficult to catch these signals in the real industrial applications.
