Embodiment

[0055] The wireless charging system in this method is a resonant optical wireless charging system. Traditional optical wireless charging is generated by resonators composed of two parallel mirrors and a gain medium between them, which are integrated into a single device, however, in resonant optical wireless charging systems, these resonator components are separated, as figure 1 shown.

[0056] figure 1 The shown resonant optical wireless charging system includes a sending end and a receiving end, the sending end includes a resonant optical wireless charging transmitter and a first communication signal transceiver, and the receiving end includes a resonant optical wireless charging receiver and a second communication signal transceiver.

[0057] In the resonant optical wireless charging transmitter, there is a first mirror R1 with 100% reflectivity and a gain medium for amplifying the passing photons. In the resonant optical wireless charging receiver, the second mirror R2 w...

Abstract

The invention relates to a wireless charging system and a transmission link establishment method. The method comprises steps that 1, scanning, a charging sending end is found by a receiving end of thewireless charging system through scanning; 2, link authentication, a link authentication request is sent by the receiving end to a certain sending end, and link authentication can be carried out under secret key and no-secret key conditions; 3, association, an association request is sent by the receiving end to the sending end, the association request is responded by the sending end when chargingconditions are satisfied, and association is established; and 4, establishing an energy transmission link, resonance light charging is carried out through forming resonance of light in a resonance cavity between the sending end and the receiving end, and the harmonic light can automatically align at the receiving end along with movement of the receiving end. Compared with the prior art, information interaction between the sending end and the receiving end of the wireless charging system is completed in a wireless communication mode, the energy transmission link is further established, and mobile one-to-multiple real-time wireless charging is realized.

Description

technical field [0001] The present invention relates to wireless charging technology, in particular to a wireless charging system and a method for establishing a transmission link. Background technique [0002] According to the Cisco Visual Networking Index (VNI) report, wireless service traffic will increase by nearly 100% every year in the future, and wireless data traffic will increase by 1000 times in the next ten years. Subsequently, the information processing capabilities of wireless communication and mobile computing devices will also continue to increase, thus putting forward higher and higher requirements for the energy supply of mobile devices. Taking the current smart phone as an example, more than 70% of the volume and weight are occupied by batteries, and this proportion is still increasing. Secondly, power supply is also a key technology of the Internet of Things and wearable devices, especially long-distance, mobile, and durable power supply is still a very c...
