The invention relates to a method for implementing mobile operation of a low-voltage distribution region based on an intelligent mobile terminal. A terminal layer, a network layer and a master station layer are mainly adopted in the method; and the method is characterized in that the terminal layer comprises the intelligent mobile terminal for carrying out tasks of touring, first-aid repairing, defect eliminating, meter reading, charging, surveying and overall protecting and exchanging which are issued by an operation management master station; the network layer is used for constructing an McWiLL (Multi-carrier Wireless Information Local Loop) electric power special wireless broadband network by arranging a service access controller SAC and a base station BTS (Base Transceiver Station), and providing safe, reliable, convenient and fast channels for real-time interaction of background and field operators; and the master station layer is used for carrying out interfacing by arranging a network device, an active service system, an SG186 (State Grid) marketing system and a production management system so as to obtain user/equipment archive data, scheduled task data and first-aid repairing task data, and implementing issuing and estimating of the tasks, and monitoring of executive conditions of field operations.
