Detection method, device and equipment of vehicle-mounted lightning arrester and medium

The invention provides a detection method of a vehicle-mounted lightning arrester. The detection method can be applied to the technical field of power equipment maintenance and the technical field of the Internet of Things. The detection method of the vehicle-mounted lightning arrester comprises the following steps: acquiring real-time electric quantity data between a target vehicle and a power supply network and a real-time image sequence of the lightning arrester in a running time period of the target vehicle; performing spectral analysis on the real-time electrical quantity data to obtain change information of the real-time electrical quantity in the operation time period; performing target detection on the visible light image sequence to obtain a first position area of the lightning arrester; based on the first position area of the lightning arrester, identifying the infrared image sequence to obtain temperature change information in the first position area in the operation time period; and obtaining the
