[0003] Since the temporary grounding device does not have a fixed signal collection point to collect its status, in the existing power supply dispatching monitoring system, it is impossible to monitor and display the temporary grounding device, which is not convenient for dispatchers to control the situation on the spot, and it is easy to cause damage to the temporary grounding device. Mis-supply power without dismantling, resulting in grounding short circuit and equipment damage

A grounding state monitoring method and system provided by the present invention are applied to a grounding state monitoring system including dispatching terminals, mobile terminals, power supply equipment and temporary grounding devices. The steps of the method include: the mobile terminal acquires the ID of the power supply equipment and generates the power supply The grounding request of the equipment is sent to the dispatching terminal; the dispatching terminal receives and displays the grounding request, and responds to the user operation and sends a grounding permission notification to the mobile terminal; after receiving the grounding permission notification, the mobile terminal obtains the temporary grounding device connected to the power supply equipment ID, and generate the grounded information of the equipment and send it to the dispatching terminal; the dispatching terminal receives the grounded information of the equipment, displays the grounding mark for the power supply equipment connected to the temporary grounding device, and prohibits sending remote control commands to the power supply equipment. In this way, the monitoring of the on-site temporary grounding device is realized, and the power transmission accident caused by the inability to judge the setting status of the temporary grounding device during the maintenance operation is avoided.
Description
technical field [0001] The invention relates to the field of power supply monitoring, in particular to a grounding state monitoring method and system. Background technique [0002] During the repair and maintenance of power supply equipment, it is necessary to connect a temporary grounding device to discharge the equipment after the equipment is powered off, so as to prevent the residual voltage from causing harm to the maintenance personnel. [0003] Since the temporary grounding device does not have a fixed signal collection point to collect its status, in the existing power supply dispatching monitoring system, it is impossible to monitor and display the temporary grounding device, which is not convenient for dispatchers to control the situation on the spot, and it is easy to cause damage to the temporary grounding device. Mis-supply power without dismantling, resulting in grounding short circuit and equipment damage. Contents of the invention [0004] In order to over...
