基于北斗通信的流动地震观测台站远程监控技术研究

A Study on the remote monitoring of the portable seismic station based on Beidou system

实现地震观测台站的远程监控对于保证观测数据质量和提高野外观测效率具有重要意义,目前国内对于高原、沙漠等无有效网络接入的偏远地区的流动地震观测尚无经济有效的远程监控方法。基于我国"北斗"卫星导航系统短报文通信功能,提出并实现适用于国内流动地震观测台站的无盲区远程监控技术。使用结果表明,自主研发的远程监控设备实现了目前流动地震观测的基本需求,通过软件通信协议扩展,也可应用于其他对通信带宽和频度要求不高、具备串口或网口通信功能设备的远程监控领域,具备一定推广性。

The remote monitoring of the seismic station have the significant meaning for improving the seismic data quality and seismic observation efficiency. However, there is no effective and economic monitoring method for the stations which are located at the remote areas without effective network access, such as the plateu, desert, etc. This paper focuses on the problem, aims to design and develop a remote monitoring device for field seismic station based on Beidou sattelite navigation system, which would make up the deficiency of domestic seimic observation system. Actual application shows that the remote monitoring device we developed achieves the basic requirements of the current portable seismic observation. Furthermore, through the modifying of the software communication protocol, this device can also be applied to the other remote monitoring areas where the communication bandwidth and frequency requirements are not high, with a serial or ethernet port interface, therefore has the broad application prospects.
