Problems solved by technology

However, due to the characteristics of the wireless channel, the energy signal of the energy transmitter will have a large fading during transmission, so that the wireless energy received by the energy receiver is too small
In addition, during the transmission of the energy signal, due to the existence of obstructions, the energy signal may be blocked or even unable to be transmitted to the energy receiver
These phenomena lead to problems such as too small energy collected by the energy receiver, low conversion efficiency, and small coverage.

Abstract

The invention discloses a wireless energy transmission system, a wireless energy transmission device, a wireless energy transmission method, an energy transmitter, an intelligent reflecting surface and a computer readable storage medium. The method comprises the following steps of acquiring the channel state information; calculating a beam forming vector and the reflection parameters of an intelligent reflection surface according to the channel state information; sending an energy signal according to the beam forming vector, and sending the reflection parameter to the intelligent reflection surface, so that the intelligent reflection surface adjusts a reflection array according to the reflection parameter, wherein the intelligent reflecting surface comprises a plurality of reflecting arrays, and the energy signal sent by the energy transmitter is directly irradiated to the energy receiver and is reflected to the energy receiver through the intelligent reflecting surface. According to the wireless energy transmission method disclosed by the invention, the wireless energy transmission efficiency is improved, and the coverage area is enlarged.

Description

technical field [0001] The present application relates to the field of computer technology, more specifically, to a wireless energy transmission method, device, system, an energy transmitter, and a computer-readable storage medium. Background technique [0002] With the development of the 5th generation mobile communication (5G) communication and post-5G in the future, the application of the Internet of Things will become more and more closely related to people's lives, and the demand for portable charging of a large number of energy transmitters such as mobile phones, tablet computers, and Bluetooth headsets will increase. It is getting stronger and stronger. [0003] Wireless energy transmission technology based on radio frequency has attracted people's continuous attention due to its characteristics of mobility, portability, and long transmission distance. However, due to the characteristics of the wireless channel, the energy signal of the energy transmitter will have a...
