摘要
介绍基于MEMS加速度计的地震触发器的测量原理和软硬件设计。该设备可检测地面加速度峰值(PGA)和地面累积绝对速度(CAV),当检测值达到设定阈值时,对外发出报警。
The measurement principle and software/hardware designs of a seismic trigger based on the MEMS accelerometer are introduced. This instrument can detect peak ground acceleration (PGA) and cumulative absolute velocity (CAV). If the test result exceeds the set threshold, the seismic switch will give alarm command.
