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

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of wireless energy transmission, and in particular relates to a system for realizing high-speed communication and wireless energy transmission based on public inductive coupling. Background technique [0002] As a power transmission method that has emerged in recent years, wireless energy transmission technology has been widely used in various fields. In the use of many consumer electronic products, the charging interface of the battery is a very critical design. Due to wear problems at the joints, failures can result. Non-contact charging can effectively avoid such problems. In some medical application fields, many artificial organs such as pacemakers need electric energy to assist power supply, and such power supply measures often require built-in batteries to complete. Similarly, the use of wireless charging technology can effectively power these in-body devices while reducing maintenance times and pai...
