摘　　要：介绍了声发射的主要特性和基本定位方法,并讨论了2种基于单片机技术的AE信号测量方案,推导了平面定位的具体定位算法,给出了时差测量的电路方案以及测量方案的硬件电路图.通过在金属平台上的敲击试验,证明了该方案的可行性.On the basis of brief introduction of the background of AE, two schemes are developed for AE measurement with singlechip computer. The plane orientation algorithm is derived. The circuit of measurement of time difference and diagrams of these methods are shown. Experiment shows that the methods are feasible by knocking on the metal plane.
