Design of a wireless network seismic sensor with posture self-correction

针对复杂的地理环境中地震数据采集多采用分布式无线采集系统,但是地震传感器布排的随机性和不确定性对地震波数据的采集有很大影响的问题。提出一种对加速度传感器姿态自校正的方法,其能够消除传感器安装位置的影响,提高地震数据质量。以C8051F020主控制器为核心,利用MEMS传感器模块采集地震波数据,通过Xbee-Pro无线射频模块实现无线数据传播,设计一种无线网络地震传感器系统。结果表明,该系统能够实现无线数据采集并对采集到的数据进行姿态校正,对复杂环境下地震波数据采集领域具有广泛的应用价值。

Since the distributed wireless acquisition system is mostly adopted for seismic data acquisition in the complex geographical environment, and the layout randomness and uncertainty of the seismic sensor has great influence on the acquisition of the seismic wave data, a posture self-correction method for the acceleration sensor is proposed to eliminate the influence on the installation position of the sensor, and improve the quality of the seismic data. A wireless network seismic sensor system was designed, which takes C8051F020 master controller as the core, uses the MEMS sensor module to acquire the seismic wave data, and adopts the Xbee-Pro wireless RF module to transmit the wireless data. The result indicates that the system can acquire the wireless data and perform the posture correction for the collected data, and has a wide application value in the seismic wave data collection field in the complex environment.
