Far-field wireless charging system and charging method based on green energy

Abstract

The invention relates to a far-field wireless charging system and charging method based on green energy. The charging system comprises an energy base station and terminal equipment, wherein the energybase station comprises an energy collection device and a direction antenna which are fixed on a communication base station; the terminal equipment comprises a first battery, a second battery, an energy converter, an energy receiving antenna, a data transceiving module and an information transceiving antenna; the energy receiving antenna is connected with the input end of the energy converter, theoutput end of the energy converter is connected with the first battery, and the energy receiving antenna is used for receiving radio waves emitted by the direction antenna; and the second battery isconnected with the power supply end of the data transceiving module, the data transceiving module is connected with the information transceiving antenna, and the data transceiving module receives andtransmits information through the information transceiving antenna. According to the invention, the efficiency of far-field wireless charging can be improved, and convenient wireless charging of large-range Internet-of-Things terminal equipment can be provided.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a far-field wireless charging system and charging method based on green energy. Background technique [0002] With the rapid development of modern communication technology, the Internet of Things has gradually entered people's lives.

The Ministry of Industry and Information Technology clearly pointed out in the "Guiding Opinions of the Ministry of Industry and Information Technology on Accelerating the Cultivation of New Models and New Formats of Shared Manufacturing and Promoting the High-quality Development of the Manufacturing Industry" that "promote the construction of new infrastructure, strengthen 5G, artificial intelligence, and industrial Internet...

AI Technical Summary

Problems solved by technology

[0004] The deficiencies of the existing research mainly lie in: in terms of far-field wireless charging, there is a lack of terminal equipment design that supports simultaneous energy reception and information transmission, resulting in low wireless charging efficiency; in terms of multi-channel radio waves simultaneously providing wireless charging, there is a lack of reasonable support. A design that modulates multiple radio waves for "constructive" charging
