Full duplex communication ICPT system based on shared channel

Abstract

The invention discloses a full duplex communication ICPT system based on a shared channel. The system comprises a power supply circuit, a primary side electric energy resonance circuit, a secondary side electric energy resonance circuit and a load circuit. A part of a winding of an electric energy transmitting coil in the primary side electric energy resonance circuit is used as a primary side signal transmission coil, and primary side signal channel circuits are connected in parallel to two ends of the main circuit, thereby forming the primary side signal resonance circuit. A part of a winding of an electric energy receiving coil in the secondary side electric energy resonance circuit is used as a secondary side signal transmission coil, and secondary signal channel circuits are connectedin parallel to the two ends of the circuit board, thereby forming the secondary side signal resonance circuit. A signal resonance network formed by the primary side signal resonance circuit and the secondary side signal resonance circuit is provided with at least two resonance points. According to the invention, the system structure can achieve the electric energy transmission and signal transmission in mutually independent resonant networks, and a part of the electric energy transmission networks has a wave blocking function, so that the signal transmission cannot influence the transmissionof electric energy, and the quality of the signal transmission and the electric energy transmission is ensured.
