摘要: 针对现有矿山微震信号采集系统存在价格昂贵且通用性不强等问题，设计了一种多通道微震信号采集系统。该系统采用地震计拾取微震信号，利用采集电路实现对微震信号的放大、数模转换及数字滤波，利用STM32将滤波后的信号通过USART实时发送给上位机进行分析处理。测试结果表明，该系统可以准确采集、记录地震计拾取的3个通道的微震信号，稳定性好、可靠性高、成本低。

Abstract: In view of problems of high cost and low universality existed in current acquisition systems of mine microseismic signal, an acquisition system of multi-channel microseismic signal was designed. The system adopts seismometer to collect microseismic signals, uses acquisition circuit to implement amplification for microseismic signals, analog-to-digital conversion and digital filter, and uses STM32 to real-timely send filtered signals to PC for analysis by USART. The test results show that the system can accurately collect and record 3-channel microseismic signals collected by seismometer with good stability, high reliability and low cost.
