WIFI (wireless fidelity) electricity control box

The invention discloses a WIFI (wireless fidelity) electricity control box. The WIFI electricity control box comprises a master control air switch, a transformer, a WIFI module, a singlechip, a relay (a), a relay (b) and a plurality of air switches, wherein the master control air switch is serially connected with the relay (a) and then is electrically connected with the transformer; the air switches are connected to one another in parallel; each air switch is serially connected with the relay (b) and then is connected to a circuit between the relay (a) and the transformer; an outputting end of the transformer is respectively connected to a WIFI transmitting and receiving module and the singlechip; the WIFI transmitting and receiving module receives control commands of a control terminal, transmits the control commands to the singlechip and feeds back feedback signals of the singlechip; and the singlechip processes the control commands, after the control commands are processed, control signals are generated, and switching-off and switching-on of the corresponding relays are controlled. The WIFI electricity control box is provided with the WIFI transmitting and receiving module and the singlechip, and various secondary circuits of the electricity control box are closely or remotely controlled through terminals such as a mobile phone and a tablet personal computer.
