Abstract

The invention provides a wireless energy and signal synchronous transmission system based on a multi-resonant technique, relating to the technical field of wireless power transmission and aiming to solve the problem that stable power output can not be obtained as the transmitted energy is affected by amplitude modulation in existing energy and signal synchronous transmission methods. The system has the beneficial effects that LC series-parallel circuits with a plurality of resonance points serve as primary / secondary side resonance matching circuits, so that different frequencies are used for energy transmission and communication respectively, thus minimizing mutual effects of energy and data while energy and data synchronous transmission is achieved; the system can be applied underwater and underground and to other media based on the communication mode of near-field resonant coupling; the system can achieve full-duplex communication and half-duplex communication of primary and secondary sides, simplex communication from the secondary side to the primary side and simplex communication from the primary side to the secondary side while energy is continuously transmitted, without extra antennae, and can lengthen the distances of energy transmission and communication by increasing the relay; the system is suitable for wireless energy and signal synchronous transmission.
