To improve the precision and synchronize the distributed node clock of the microseismic monitoring system, it proposes a microseismic data synchronization acquisition design based on Precision Time Protocl(PTP) clock agreement. Firstly, it chooses the computer clock as the main system clock, STM32 as the processor and IP178CH as clock divider of the network card driver design implanted PTP clock protocol. And then, it sends the synchronization signal to each acquisition node of the net work periodically through the clock divider. Finally, it makes each node of the RTC clock synchronized with the master clock through the calibration from the time deviation and the Network delay time, thus achieves the synchronization of data acquisition node and makes the precision of the clock synchronization arrive at us class. 
