【摘要】 为了实现破坏性地震强度的速报,提高地震应急响应效率,指导抗震救灾,设计一种新型地震烈度计。采用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,保证仪器整体性能,能够满足地震烈度速报需要;此外,该地震烈度计具有开关量输出,可以作为地震紧急处置系统的地震开关来使用,实现一机多用,一机多能。更多还原

【Abstract】 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.ADS 1274 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.更多还原
