Development of mine seismic recorder based on GPS technique
Qingqing Zhang · Journal of Xi'an Shiyou University · 2013
A mine seismic recorder is developed based on the timing function of GPS.For the precise clock synchronization among different mine seismic recorders,a temperature compensation crystal oscillator and corresponding frequency division circuit are used in the recorder.A GPS timing circuit and timing flow chart is also provided.This seismic recorder can record and store data independendy and collect data after data acquisition,the data acquisition experiment result of the recorder is presented.
