Title: GROUNDING MONITORING SYSTEM, METHOD AND DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM
Abstract:
A grounding monitoring device (7, 92), method and system, and a computer-readable storage medium, relating to the field of coal mine safety. The device (7, 92) comprises: a measuring power supply (13), for powering the grounding monitoring device (7, 92); a resistance measuring device (9), connected between the measuring power supply (13) and a grounding electrode (5, 91); the resistance measuring device forms a current detection circuit with the measuring power supply (13) and the grounding electrode (5, 91) by means of the earth; and the resistance value of grounding resistors is determined according to the current flowing through the grounding electrode (5, 91) in the current detection circuit, so as to determine the monitoring result. Said solution can improve the reliability of grounding safety.
