摘　　要：针对目前煤矿井下地震仪有线连接、施工复杂的问题,研制出了一种节点存储式矿用地震仪。详细介绍了地震仪的硬件组成和功能,仪器采用地震专用数据采集芯片和基于GPS的授时守时电路,并研制了电磁感应式震源同步触发装置。In view of problem that coal mine seismograph are connected with wire and operate complication. A mine seismic exploration instrument which is node and storage type is designed. The hardware and function of the seismograph are introduced in detail. The instrument adopts the seismic data collection chip and the GPS-based timing and time-keeping circuit are used. Meanwhile, the electromagnetic induction type source synchronous trigger device are developed.

关 键 词：GPS授时仪 同步触发装置 守时电路
