Embodiment Construction
[0043] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0044] The present invention provides a flowchart of a preferred embodiment of a wireless charging method for fast handshaking between devices, as shown in image 3 As shown, the method includes:
[0045] Step S100, real-time detection of the distance between the energy receiving device and the energy transmitting device.
[0046] During specific implementation, the energy transmitting device may be a power transmitting unit (Power Transmitting Unit, PTU). In the following embodiments, the PTU is used instead of the energy transmitting device. The energy receiving device may be a power receiving unit (Power Receiving Unit, PRU), and the PRU is use...

The invention discloses a wireless charging method, system, device, energy transmitting device and receiving device. The method includes: detecting the distance between the energy receiving device and the energy transmitting device in real time; when the energy transmitting device detects the distance between the energy receiving device and the energy receiving device When the distance is less than a predetermined value, the energy receiving device obtains the identification information of the energy transmitting device, and sends a unicast message to the energy transmitting device according to the identification information; when the energy transmitting device receives the unicast message, it establishes an Connect to start charging the energy receiving device. In the present invention, the energy receiving device obtains the identification information of the energy transmitting device through an out-of-band mechanism, and realizes sending the information of the energy receiving device in the form of unicast, and the energy receiving device can send a connection request without making other judgments, reducing waiting time, and also The cross-connection between multiple devices is avoided, and the safety of the energy receiving device and the energy transmitting device is improved.
Description
technical field [0001] The present invention relates to the technical field of consumer electronics, in particular to a wireless charging method, system, device, energy transmitting device and receiving device. Background technique [0002] With the popularity of smart terminals, people have more and more smart devices that they carry with them, such as smart phones, tablets, wearable devices and so on. While people enjoy the convenience brought by these devices, they are often troubled by charging these devices. Whether it is convenient to charge anytime and anywhere in some daily work and life places is becoming a trend. According to the forecast of IHS, by 2018, the number of devices with wireless charging function will reach 1 billion. There are currently two main wireless charging technologies: the inductive type of WPC (Wireless Power Consortium) and the resonant type of A4WP (Alliance for Wireless Power). Among them, the resonant charging method is becoming the tre...
