Description

technical field [0001] The present invention relates to IPC classification G01V3 / 00 electric or magnetic prospecting or detection equipment technology, especially a solar power-powered field geoelectric and geomagnetic high-density dot matrix measurement and acquisition big data system. Background technique [0002] The earth can be divided into five parts: crust, upper mantle, mantle, outer core, and inner core. Among them, the crust refers to a thin shell mainly composed of igneous rocks, metamorphic rocks and sedimentary rocks between the earth's surface and the Moho interface. Below the crust is the mantle, and the upper mantle is mostly made of olivine. The dividing line between the crust and mantle is called the Mohs discontinuity. The earth-going current of direct current transmission mainly propagates in the crust and upper mantle, so the research on the earth resistivity structure parameters in these two regions is of great significance.

Problems solved by technology

[0010] Earthquake disasters have always caused great harm to human beings. Geoelectric measurement is very important in the data of earthquake advance prediction. At present, the accuracy of geoelectric monitoring instruments is not high, and the measurement parameters are single. They only measure DC signals and do not measure low frequency. The geoelectric signal is not measured, and the geomagnetic signal is not measured, and the multi-channel and terminal data processing capabilities are emphasized, resulting in an increase in manufacturing costs, a reduction in layout and inconvenient

[0011] In the past, similar instruments and equipment were expensive, and the measurement channels were concentrated, and the data was centrally processed before data transmission. Therefore, generally only a few monitoring points can be arranged in a city or county, so the density is small and the amount of data is small. In the later data processing process The amount of available data is very large, and it is easy to cause misjudgment
