Research of PC- MEMS seismic data acquisition and early warning information transmission system
【摘要】 我国地震预警新的技术系统研发正处于起步阶段,根据PC-MEMS(使用MMES加速度计进行数据采集并在PC端配置具有数据解析、处理、传输等功能软件的系统设备)地震预警系统技术需求,结合C/S软件架构,以边缘计算为技术思路,将数据计算移到了客户端,只须将计算结果信息传给预警中心,减少了数据传输的信息量和预警中心的工作,大大提高了预警系统在大地震时的时效性和可靠性。使用C#编写完成了PC-MEMS地震数据采集预警信息传输软件,实现了PC-MEMS数据自动采集、数据处理、参数远程配置、自动触发及地震事件自动保存等核心功能以及频谱分析、地震回放、远程下载数据等附属功能,使得软件的应用得以扩展,最后展示了通过人工触发和接收到预警信息时软件的运行示例,检验了软件运行的准确性。统计了边缘计算方式与预警中心计算方式所使用的时间,表明了使用边缘计算方式在地震预警软件中的优越性。
【Abstract】 The research and development of a new technology system for earthquake early warning in China is in its infancy. According to the technical requirements of thePC-MEMS(MMES accelerometer is used to data collection, and configure system equipment with data analysis, processing, transmission and other functional software on the PC side) earthquake early warning system, combined with the C/S software architecture, with edge computing as the technical idea, the data calculation is moved to the client, and only the calculation results are required. The information is transmitted to the early warning center, which reduces the amount of data transmitted and the work of the early warning center, and greatly improves the timeliness and reliability of the early warning system during a major earthquake. Using C#, the PC-MEMS seismic data acquisition and early warning information transmission software was completed, which realized the core functions of PC-MEMS data automatic acquisition, data processing, remote parameter configuration, automatic triggering and automatic preservation of seismic events, as well as spectrum analysis, seismic playback, Auxiliary functions such as remote downloading of data enable the application of the software to be expanded. Finally, an example of the operation of the software when the early warning information is received through manual triggering is shown to verify the accuracy of the software operation. The statistics of the time used by the edge computing method and the early warning center computing method show the superiority of using the edge computing method in earthquake early warning software.
