【摘要】 文章论述了用于地震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滤波及其它处理,分为两路信号分别送到耳机监听通道和A/D通道进行转换后,再作进一步数字信号处理后,送到LCD上显示,以发现废墟中是否有生存的人员,并进一步确定人员的位置;通过实验验证,本系统已可用于实际生命探测行动。更多还原

【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 processed signal will be divided into two signal,one to the way of headphone monitor,another to the way of A/D for converting.Finally,the signal will be displayed on the LCD after the further data processing.The instrument can be used in practical rescuing process,it has been tested by the experiment.更多还原
