介绍了一种基于无线数据采集的地震波定位系统设计方法。该系统以C8051F020单片机为主控芯片,利用GPS模块提供的PPS信号实现分布式采集系统的同步,利用无线射频模块XBeePro实现数据的无线传输。整个系统通过上位机进行实时控制。实验证明,该系统能够实现严格同步采集,整个采集系统工作稳定、操作简单,具有较高的工程应用价值。

This paper introduces a method of the seismic data acquisition system based on wireless network. The system takes C8051F020 single chip microcomputer as main control chip, uses GPS module to provide the PPS signal to realize the synchronization of distributed acquisition system, and uses the radio frequency module XBee-Pro to realize the wireless transmission of data. The whole system is controlled by PC in real time. Experiments show that the system can realize strictly synchronous acquisition, the acquisition system works stably, and the operation is simple. It has high engineering application value.
