A method for achieving binary coding communication by controlling a vibration manner of a smart phone vibrator involves a smart phone (104) with a vibration unit (1041) and is characterized in that App software (1042) written according to a communication protocol and used for controlling the vibration unit (1041) to generate a vibration signal is installed in the smart phone (104). Correspondingly, an electric automobile charging gun controlled by the vibration signal comprises a power plug (101), a cable control box (102) with a power supply unit (1023) and a charging gun head (103). A control circuit is arranged in the cable control box (102) and comprises a vibration sensor unit for receiving the vibration signal, an amplification, detection and shaping unit (1022), a single-chip microcomputer master controller unit (1024), a charging execution unit (1026) running according to the communication protocol, an electronic lock control unit (1025) and the like. By the adoption of the method, no key needs to be designed on the cable control box (102), no remote control unit is needed, and the cable control box (102) can be operated through the smart phone (104).
