The invention relates to a power supply maintenance method and system based on wireless communication. The method comprises the following steps: acquiring basic information of a maintenance power box, an electric tool and a maintainer; in the cloud server, equipment and personnel auditing is carried out, and if the equipment and personnel pass the auditing, a remote power supply contactor of the maintenance power box is switched on; the safety controller judges whether an auxiliary contact signal of the earth leakage protection test button is received or not within the first time after the electromagnetic lock is unlocked, and if not, the maintenance power box is marked as unsafe; if yes, judging whether a disconnection signal of the incoming line switch is received in a later second time, and if not, marking the maintenance power box as unsafe; if yes, whether the current exceeds the first multiple of the rated current of the electric tool or the situation that leakage protection action is triggered occurs i
