摘要
设计和实现了一种用于灾害救援的单通道便携式声波/振动探生仪。能够实现对地下声/振信号的捕捉、放大功能,并以声音的方式传送至监听耳机,以供救援队员确定该区域是否有生命存在,为进一步使用多通道声波/振动探生仪等系统救援设备进行准确、系统的救援提供可靠的依据,能大大提高救援速度。该设备灵敏度高,体积小,功耗低,通过实验验证,可用于实际救援和信号探测工作。
One kind of single - channel portable life explorer （ SC- PLE） based on sound wave/vibration for lifesaving after natural disaster is designed and implemented. It collects and amplifies various vibrations from the ruins then sends that to the monitor aground, owing to which, the rescuing team can confirm whether there are survivals under the ruins. It would offer credible evidence for the further precise and system research and rescue, and can also improve the efficiency. The SCPLE has a high sensitivity, portable size and low power consumption. The experiment shows that it can help a lot in the search and rescue work.
