Thermoelectric field potential measuring device and observation method

The invention belongs to the technical field of geophysical exploration and investigation, and particularly discloses a thermoelectric field potential measuring device and an observation method. And the problem of interference of environmental noise on acquisition results is solved. The measuring device comprises a reference non-polarized electrode, a plurality of groups of acquisition nodes and a data integration center, wherein the reference non-polarized electrode is used as a reference point for measurement of all the acquisition nodes. And each group of acquisition nodes comprises a non-polarized electrode for acquisition, a red copper electrode, a signal conditioning board card, a signal feedback board card, a signal acquisition board card, a data acquisition control board card, a satellite receiver board card and a LoRa wireless communication sending board card. The signal conditioning board card is respectively connected with the reference non-polarized electrode, the acquisition non-polarized electro
