基于单片机的普及型地震报警器设计与应用

Design and application of alarm device for earthquake prediction based on single-chip computer

依据震级与地震加速度的关系,用单片机、三轴加速度传感器、时钟芯片、数模转换器、声音报警、字符显示等功能模块,设计了普及型地震报警器。论述了系统硬件的设计方法与实现过程;用仿真软件分析了震级与地震加速度的关系;介绍了系统控制软件的编程思想;模拟地震烈度并实现了声音警报,实时记录并显示震级大小及地震时间等信息。该普及型地震报警器设计新颖、灵敏度较高,不需复杂调试即可使用,还可开发系列应急功能,对预警减灾有积极的现实意义。

The accurate prediction of earthquake is a universal problem.The earthquake prediction would provide a possible and valuable moment time for people to escape with life.According to the relationship between earthquake grade and its accelerated speed,an affordable earthquake alarm system is designed by using the single-chip computer,three axis accelerated sensors,clock chip,digit-analogue(D/A)converter, sound alarm,character display and so on.The process realization and hardware design are discussed.This article analyses the relationship between the earthquake grade and its accelerated speed by using the simulation software,introducing programming idea of system control software,simulating the earthquake seismic intensity,and carried out the sound alarm device,the real-time recording and display earthquake grade and time information and so on.Based on single-chip computer,this affordable earthquake system is new,sensitive and easy to debug.Its function for emergency,lighting,building alarm and especially early mitigation would be a meaningful future research and application.
