System for achieving high-speed communication and wireless energy transmission on basis of public inductive coupling

The invention discloses a system for achieving high-speed communication and wireless energy transmission on basis of public inductive coupling. The system comprises a powering unit and a powered unit, wherein the powering unit comprises a power transmission module and a communication signal receiving module, and the powered unit comprises a power receiving module and a communication signal emitting module; the power transmission module is coupled with the power receiving module on the basis of public inductance; the power transmission module is coupled with the communication signal receiving module, the power receiving module is coupled with the communication signal emitting module, and power transmission and communication signal transmission are based on different kinds of transmission frequency. Compared with a traditional wireless energy transmission circuit without a communication function, the system has the advantages that the communication function is increased, meanwhile, cost and the size are basically not increased, and a control mode of the traditional wireless energy transmission circuit is not changed; the communication speed is high.
