地震勘探方法被广泛应用于煤炭、石油、天然气等资源探测。采集同步精度是地震数据采集系统的一项重要技术指标。文章通过分析地震勘探系统的几种同步方法，提出一款新型一体化折射地震仪，介绍该套折射地震仪同步采集的实现方法，即GPS授时同步技术与高精度恒温晶振相结合，采用FPGA设计秒脉冲同步电路、晶振驯服电路来解决由于星历变化或障碍物屏蔽导致个别折射仪接收不到GPS信号而不能同步的问题。

The seismic prospecting method is widely used in coal, oil, gas, and other resource exploration. The acquisition synchronization precision is an important technology indicator for the seismic data acquisition system. The paper, by analyzing several synchronization methods of seismic prospecting system, puts forward a new integrative refraction seismograph, and introduces the synchronization acquisition implementation method. That is, combine the GPS clock synchronization technology and high-precision OVXO, and adopt the FPGA to design circuit to solve such a problem:due to ephemeris change or barriers, some refraction seismograph couldn't receive the GPS signals.
