低成本地磁场监测设备的设计与实现

Low-cost geomagnetic field monitoring equipment: design and implementation

摘要:

为能够在短时间内建成区域高密度地磁场观测台网,实现地磁场数据成网、成片观测，需要解决精准捕捉极震区特大震前磁场异常现象的问题。项目组利用物联网通信技术,基于RM3100三轴磁传感器,开发低成本地磁场监测设备,并部署在天津市宝坻区、武清区,同时利用人工智能数据分析技术和时序数据存储技术,开展地震前兆异常自动判定和可视化预报技术研究。该成果在2022年6月23日天津宝坻M2.0地震中得到了验证,说明低成本地磁场观测系统不仅对大震有察觉,对于近距离的中小地震同样敏感。

Abstract:

We developed low-cost magnetic field monitoring equipment to accomplish the rapid establishment of a regional high-density geomagnetic field observation network, which is capable of recording geomagnetic field data and precisely identifying magnetic field anomalies preceding major earthquakes in the meizoseismal region. The devised equipment—based on Internet of Things communication and RM3100 triaxial magnetic sensors—was deployed in the Baodi and Wuqing Districts of Tianjin. Subsequently, the automatic judgment and visual prediction of earthquake precursor anomalies were investigated by employing artificial intelligence data analysis and temporal data storage techniques. The effectiveness of the proposed monitoring equipment was verified during the M2.0 earthquake that struck Baodi, Tianjin, on June 23, 2022, demonstrating its ability to detect anomalies preceding major earthquakes and its sensitivity to small-and medium-magnitude earthquakes over short distances.
