Secondary cable power transmission line safety monitoring system, method, equipment and medium

The invention discloses a secondary cable power transmission line safety monitoring system, method and device and a medium, and relates to the technical field of cables. The voltage near the power transmission line is detected through a sensor to obtain detection data. Detection data are calculated and analyzed through the voltage data acquisition and signal processing module, and electric field intensity and induced voltage are generated and sent to the second wireless communication module through the first wireless communication module. And receiving the electric field intensity and the induced voltage sent by the second communication module through a main control processing module in the rear early warning end, and comparing the electric field intensity and the induced voltage in combination with a preset safety threshold to generate safety early warning data. And finally, an acousto-optic reminding module carries out alarm operation according to the safety early warning data to generate safety monitoring
