AC charging pile ordered charging CC and CP signal equipment and control method

The invention relates to the technical field of automobile charging, in particular to signal equipment and a control method for ordered charging CC and CP of an alternating current charging pile, and the signal equipment comprises a user side, a cloud platform, a charging pile and an automobile side; the start-stop control unit is used for controlling the charging state of the automobile end by controlling PWM signals on CP and CC signal lines connected with the charging pile body and the automobile end; when detecting that the states of the CP and CC signal lines are changed, the automobile end controls an internal resistance switch of the automobile end to change the state of a charging gun, and the start-stop control unit controls the CP and CC signal lines to enable an automobile at the automobile end to be recognized as a non-gun-insertion state; and when the PWM signal state is changed again, the start-stop control unit controls CP and CC signal lines to enable the vehicle at the vehicle end to be recog
