摘　　要：针对地质灾害发生时周围地质层都会受到不同程度的振动的特点,在当地质灾害发生时监测其振动情况,为了给人们争取逃生时间,在此基于MEMS加速度传感器和GPRS模块,采用MSP430单片机设计了一种小型、快速、低功耗的振动监测报警系统,给出了系统的基本结构和电路实现的解决方案。试验结果表明本系统灵敏、可靠。Before the happening of geological hazard,its surrounding geological layers are affected by change of vibration.According to the characteristic,a small-sized,low-power and rapid detecting system is designed for monitoring the geological layer vibration to get more time for people to escape when geological hazard happens.It is based of the MEMS sensors,GPRS module and MSP430.The solution to realize the circuit and the basic architecture of the system is given.The result shows that the system is sensitive and reliable.
