| 摘 要： | 本文论述了基于CPLD的用于灾害救援中的实用声振救生仪的设计与实现方法。通过重力加速度传感器拾取被救人员发出的敲击信号,然后经过前级调理板的放大和次级放大和滤波及其它处理,再进行进一步数字信号处理后送到耳机监听通道,以发现废墟中是否有生存人员,并进一步确定位置。

| Abstract: | The design and the implementation of the rescuing system are introduced,which can be used in the rescuing process of the earthquake.It collects the picking signal by the wrecked man via the sensor based on the acceleration of gravity.Then the system process the signal by magnifying,filtering,and some other processing.And again,the signal will be displayed to the way of headphone monitor,The instrument can be used in practical rescuing process to find if the person was live and make sure the location where the person. |
