Monitoring method, device and equipment of mine power supply system and medium

The invention provides a monitoring method and device of a mine power supply system, equipment and a medium, and relates to the technical field of data processing. The method comprises the following steps: acquiring a power supply topological graph corresponding to a mine power supply system; for a first cable connected between any two nodes in the power supply topological graph, obtaining loss information of the first cable; determining whether at least one second cable in the first cables is abnormal or not; in response to existence of a second cable in the first cables, performing abnormal labeling on the second cable in the power supply topological graph, and performing loss information labeling on the first cables; and displaying the marked power supply topological graph. Therefore, the loss information of each cable is marked in the power supply topological graph, and the abnormal cable is marked, so that related workers can timely know the abnormal cable and the loss of each cable, and the cables in th
