Further, the system controller 110 is configured to perform the following processing:

First, the system controller 110 determines the power equipment that needs to be temporarily supplied with power, and acquires a plurality of the power box use conditions of the power equipment. Specifically, when the power equipment needs to be overhauled and the power box 120 needs to be used for temporarily supplying power to the power equipment, a related overhauler can submit an overhauling application at an upper computer, the system controller 110 receives the overhauling application and sends the overhauling application to an auditing upper computer used by the related auditor, wherein a factory area and an area need to be selected in the application content, the power equipment needing to be temporarily supplied with power and fault phenomenon information of the power equipment are filled in, the related auditor audits the overhauling application, the device is approved to be used after the auditing passes, approval information is sent to the system controller 110, the system controller 110 responds to the approval information, determines the power equipment needing to be temporarily supplied with power according to the overhauling application, and obtains a plurality of power box use conditions which are stored in advance in a mapping mode with identification information of the power equipment from a local database.
