technical field [0001] The invention belongs to the field of geomagnetic anomaly monitoring, and in particular relates to a mobile Internet-based global earthquake geomagnetic anomaly big data monitoring and early warning system and a monitoring and early warning method. Background technique [0002] Earthquake is one of the major natural disasters faced by human beings. The loss caused by a strong earthquake is very huge. All countries are working on the monitoring and early warning research of earthquakes. [0003] The "Law of the People's Republic of China on Earthquake Prevention and Disaster Mitigation" encourages and guides social organizations and individuals to carry out mass earthquake monitoring and prevention activities to monitor and prevent earthquakes; earthquake prediction opinions should be reported to the competent national authorities.

AI Technical Summary

Problems solved by technology

Unfortunately, nature's strong warning signals through geomagnetic disturbances before major earthquakes have been ignored.

[0030] 5. At present, global geomagnetic monitoring is constrained by high construction and maintenance costs, and the number distribution is very limited

For example, the Beijing Jinghai Geomagnetic Observatory is the only professional geomagnetic comprehensive observation station in the capital area. It is constructed using carbon fiber non-magnetic technology, which requires high construction requirements and high costs.

[0032] 6. In order to monitor geomagnetic anomalies more accurately, dense distribution of points is necessary, but it is difficult to do so in practice

At the same time, in order to effectively analyze the data, it is necessary to analyze the data of multiple stations in order to eliminate the abnormal data. It is necessary to judge the geographic location of the source of the magnetic field anomaly and the scope of the affected data according to the change intensity of the geomagnetic data at different stations. The data can only be completed, which is not capable of the existing geomagnetic station model

[0033] 7. Geomagnetic monitoring requires a global layout

[0036] The solution that is relatively close to the method of the present invention: the idea of ​​the International Geomagnetic Station Network (INTERMAGNET) is also global data sharing, but it is a professional station construction mode, and the data is seriously insufficient. There are only about 144 networked stations in the world, and the professional geomagnetic stations of various countries There are problems of high construction and maintenance costs, insufficient distribution points, and insufficient effective data. At the same time, there is a lack of real-time automatic early warning and analysis of earthquake and geomagnetic anomaly big data; No.: 201510049262.1 "Seismic Data Recording and Analysis System Based on Mobile Phone Seismic Monitoring Network" "Using mobile phone records and earthquakes to obtain the vibration and geomagnetism of each location monitored at each stage before, during, and after the earthquake. Provide a system that is more comprehensive than the monitoring data of traditional seismic stations, and can solve the problems of insufficient seismic data at professional seismic stations, insufficient post-earthquake data, and insufficient aftershock data.” This solution is a good idea

However, there is a lack of solutions for mobile devices using shaking abnormal data. The data error can reach more than 15% when moving. There is a lack of non-professional sensors that can monitor and define the magnetic field range. There is a lack of research on earthquake geomagnetism. For example, the accuracy of professional equipment can reach 0.1nT. level, while the accuracy of mobile phone magnetic field sensors is generally 40-200nT, and the basic variation value due to environmental interference is generally around ±500-1500nT, so the proposed "provide more comprehensive data than professional geomagnetic stations" is inaccurate and unrealizable

[0037] There will be geomagnetic anomalies before earthquakes, but at present, this geomagnetic anomaly cannot be used to warn people
