摘　　要：针对矿用节点式地震仪无主机、无大线,各台之间独立工作的特点,采用GPS授时技术实现各台地震仪之间的时钟同步。分析了GPS授时技术的原理,设计了GPS时钟同步的电路,在嵌入式ARM9处理器上开发了GPS授时控制软件,并在实际应用中得到验证。GPS technology to achieve timing synchronization between each seismograph clock is used by us, for mine node type seismograph no host, no line between each independent characteristics. The principle of GPS timing technology is analyzed, the circuit design of GPS clock synchronization, GPS timing control software of embedded ARM9 processor are developed, and the effect is verified in pratical application.
