The invention provides a magnetic resonance coupled wireless charging system based on photoelectric encryption technology. The primary transmitting coil of the system and the load circuit transmit energy through the electromagnetic coupling connection between the single-chip computer control switch group, the resonance unit and the load circuit. The primary circuit to be decrypted and the load circuit transmit the request charging signal and key information through the electrical signal encryption unit, the electrical signal control LED optical frequency signal unit, the specific frequency LED light emitting unit, and the LED optical signal frequency decoding unit. Encryption of electrical energy transmission can be achieved by applying optoelectronic encryption to the frequency. A single-chip microcomputer programming is used to generate a linear encryption key to realize the unpredictability of frequency adjustment. The effect of the present invention is to realize directional supply to charging electronic equipment through photoelectric encryption means, improve the safety of wireless charging, and meanwhile provide lighting function in the way of LED light encryption.
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...
