英文摘要：

In order to solve the time synchronization problem of seismic exploration and other areas, a synchronization technology project based on the GPS time dissemination is designed, which uses the real-time, continuity and high-precision PPS signal as the benchmark to calibrate the local clock, and makes use of the wireless communication and single chip microprocessor to achieve the data collection synchronization. By synchronizing the seismic data collected by wireless remote sensing, the problem of real-time in collection and storing process has been solved when the data collected by the local seismic explorers become larger. Especially, the key problems of independence synchronization and time-sharing processes existing in future digital seismic detectors can be solved.
