为了能实现对破坏性地震的强度进行速报，提高地震应急响应效率，指导抗震救灾，设计了一种新型地震烈度计。设计中采用了性价比较高的微机电加速度计MODEL-1221作为地震传感器；利用4个通道的同步24位模数转换器ADS1274进行地震信号转换；使用32位的嵌入式处理器AT91RM9200作为地震事件的判定和烈度参数计算的平台，既保证了仪器整体性能能够满足地震烈度速报的需要；此外，该地震烈度计还具有开关量输出，可以将其作为地震紧急处置系统中的地震开关来使用，实现了一机多用，一机多能。

In order to realize the rapid report of devastating earthquake intensity and improve the efficiency of earthquake emergency response to guide the disaster relief , a new type of seismic intensity meter was designed. MODEL-1221 as higher cost-effective MEMS accelerometer, was designed as seismic sensors. ADS1274 was utilized for four channels simultaneously 24 ADC to convert seismic signal. 32-bit embedded processor AT91RM9200 as seismic events determination and intensity parameter computing platform was also used to ensure the overall performance of the instrument can meet the needs of seismic intensity rapid report. Additionally, the seismic intensity meter also has a digital output, which can be used as an emergency earthquake disposal system switches to use which implements as a multi-purpose and multi-function.
