The invention discloses an intelligent electrical appliance control device which comprises a first communication unit, a processor, a second communication unit and a relay; the first communication unit is used for forwarding packets between the processor and a main control terminal, and realizing the information interaction of the processor and the main control terminal; the second communication unit is used for forwarding packets between the processor and an electrical equipment, and realizing the information interaction of the processor and the electrical equipment; the processor is used for controlling the connection or disconnection of the relay according the information carried in the forwarded packets; and the relay is connected between an ac power supply end and the electrical equipment in series. The technical proposal includes that the main control terminal realizes the complete start-up or shutdown of the electrical equipment on the premise that the user has no need to manually connect or disconnect the power supply of the electrical equipment. Besides, the main control terminal can set or query the work state of the electrical equipment through the intelligent electrical appliance control device.
