Indoor wireless energy transmission system and wireless energy transmission method

Abstract

The invention discloses an indoor wireless energy transmission system and a wireless energy transmission method. The energy transmission system comprises a power receiving end and a power transmitting end, wherein the power transmitting end is composed of a power transmitting array, a signal analysis circuit, a signal processing module, a variable power amplifier and a power monitoring module; the power transmitting array in a receiving mode is sequentially connected with the signal analysis circuit, the signal processing module, the variable power amplifier and the power monitoring module; the power transmitting array in a transmitting mode is connected with the variable power amplifier; and the power receiving end is composed of multiple to-be-charged devices, and each to-be-charged device is composed of an energy receiving antenna and a rectifier circuit. The problems that the traditional method of using electromagnetic wave propagation for wireless energy transmission is only applied to a power transmitting array formed by antennas by regularly-arranged units with the same structure, single-frequency operation exists, the multi-target beam optimization time is long, serious interference is generated to a device in no need of charging, and safety of a person, an animal, a plant and a device in no need of charging in the energy transmission space can not be ensured can be solved.

Description

technical field [0001] The present invention relates to wireless energy transmission, in particular to a system using electromagnetic wave propagation for wireless energy transmission, in particular to an indoor wireless energy transmission system and a wireless energy transmission method using time inversion technology, a rectifier circuit, an antenna and an antenna array. Background technique [0002] Thanks to the advent of wireless communication, life has become more and more convenient and efficient. People are also gradually realizing that not using cables to power a large number of stationary / mobile portable devices will make these electronic devices truly "portable". Wireless power transmission (WPT) is this method of power supply that does not require cables. Unlike wireless communication, WPT transmits energy rather than data. Electronic devices to be charged, such as mobile phones, tablet computers, etc., can convert the electromagnetic energy from the power tra...
