Abstract

The invention provides a magnetic resonance coupling wireless charging system based on photoelectric encryption. Energy transfer is carried out on a primary side transmitting coil and a load circuit of the system through electromagnetic coupling connection among a single chip microcomputer control switching group, a resonance unit and the load circuit. Transfer of a charging request signal and secret key information is carried out on a primary side circuit to be decrypted and the load circuit through an electric signal encryption unit, an electric signal control LED light frequency signal unit, a specific frequency LED light-emitting unit and an LED light signal frequency decoding unit. Electric energy transmission can be encrypted by carrying out photoelectric encryption on the frequency. One-time linear encryption is carried out by applying a single chip microcomputer programmer to generate a secret key, so that frequency adjustment unpredictability is realized. The magnetic resonance coupling wireless charging system has the advantages that directional supply is achieved for charging electronic equipment is achieved, wireless charging safety is improved, and meanwhile an illuminating function is provided in an LED light encryption mode.

Description

technical field [0001] The invention relates to the field of wireless charging technology and visible light communication technology, in particular to a magnetic resonance coupled wireless charging system based on photoelectric encryption. Background technique [0002] Electromagnetic waves are the basic medium of modern communication technology, which can better carry and transmit various types of information. Visible light, as a kind of electromagnetic wave, not only has the above advantages, but also has the following characteristics that other wave bands do not have, which makes it have the advantages of being applied in the field of encryption technology. First of all, the linearity and directionality of visible light transmission are better, which is convenient for directional transmission of information; second, visible light will not penetrate walls. This means that when visible light is used in the field of communication, the security is higher, and the information...
