摘　　要：针对地震动信号采集系统电路可靠性低、设计复杂的问题,基于大量地震波理论并结合过零数分析,利用MMAS传感器和DSP设计了一种信号采集与处理系统。试验结果表明,该系统结构简单、可靠性较高,可有效识别由人员与车辆运动引起的地震动信号。Aiming at the drawbacks of lower reliability and complicated design of the circuit for seismic signal acquisition system,a signal acquisition and processing system,based on seismic wave theory and analysis of zero-crossing number,has been designed with application of MMAS sensor and DSP.Experimental results show that this system has simple structure and high reliability and it is capable of effectively identifying seismic signal caused by the movement of people and vehicle.
