摘　　要：为实现地震信息的报警及生命信息的探测,设计了地震检测报警系统。根据地震波的特点,采用加速度传感器检测地震波,经单片机分析、处理后,判断地震发生与否。如果检测到地震发生,警报系统第一时间向人们发出地震警报和逃生语音提示,之后通过内置的生命探测红外传感器探测周围的生命信息,当检测到被困人员时,无线发射模块向外界发送两种不同频率的电磁波,进行无线求救和语音求助,以求最大限度地减少地震灾害造成的损失。In order to realize the alarm of seismic information and detection life information, an earthquake alarm is designed. According to seismic wave characteristics, the acceleration sensor is used to detect seismic waves and determine whether the earthquake occurred. If it detects an earthquake, warning system would alarm and give a voice to escape at the first time. The built-in infrared sensor would detect life information around. When trapped personnel are detected, two different kinds of electromagnetic waves are sent to the outside world by wireless transmitter module different for wireless and voice help to minimize losses caused by the earthquake.
