生命探测信号在强震作用下的波动特性分离
Separation of Fluctuation Characteristics of Life Detection Signals Under Strong Earthquakes
摘要
Abstract
Earthquake disaster seriously affects the safety of people's lives and property,and the difficulty of earthquake relief is more difficult in the harsh environment after the earthquake,which puts forward higher requirements for rescue technology and life detection equipment.The current seismic rescue equipment,especially the life signal exploration equipment,has many problems,such as huge volume,small detection range,complex operation,and poor anti-interference ability.It is difficult to judge the validity of life signal and the accurate range of life signal.In view of the above problems,a micro acoustic life detection system based on the separation of wave characteristics under strong earthquakes is proposed,which can detect the life signal more accurately,so as to quickly complete the rescue and cleanup work after earthquake.The system is verified by experiments.It is proved that the micro acoustic life detection system has wide range of detection of life signal,strong anti-interference ability,and accurate positioning of life signals,which is of great significance for better completion of earthquake relief work.关键词
