The invention relates to a wireless parallel transmission method for an energy and signal shared channel and belongs to the field of radio energy transmission. The wireless parallel transmission method is used for solving the problem that the implementation of synchronous transmission of wireless energy and information needs two channels. According to the wireless parallel transmission method for the energy and signal shared channel, provided by the invention, a system primary side circuit and a system secondary side circuit adopt a pair of coils as a shared channel and achieve the parallel synchronous transmission of the information and the energy by adopting the same frequency; the system primary side circuit achieves the forward transmission of the information in a variable frequency manner, and the system secondary side circuit achieves the reverse transmission of the information in a controllable rectifying manner. The method is applied to wireless radio energy transmission.
