Abstract

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.

Description

technical field [0001] The invention relates to a wireless parallel transmission method for energy and signal sharing channels, belonging to the field of wireless energy transmission. Background technique [0002] Since Marin Sauljaksi and others from the Massachusetts Institute of Technology made new progress in the field of wireless power transmission in 2007, various research institutions at home and abroad have taken further explorations, gradually shifting from wireless to wireless. Energy transmission transitions to synchronous transmission of energy and information, but the existing wireless synchronous transmission of energy and information is usually limited to one-way transmission of energy and information, if two-way transmission is to be achieved, two channels are required. Contents of the invention [0003] The purpose of the present invention is to solve the problem that two channels are required for synchronous transmission of existing wireless energy and in...
