Problems solved by technology

This patent divides the priority of multi-device charging, and selects the appropriate charging scheme for different conditions. However, considering the time-division charging of mobile devices with different frequencies, the charging efficiency is reduced, and there is no such thing as mobile devices meeting various conditions. Address specific priority issues
[0008] Since the single wireless charging technology has been relatively mature, many companies at home and abroad have been researching the multi-device wireless charging technology. The existing papers and patents only propose some simple solutions on the charging scheme, and there is no good solution. systems and solutions

Embodiment 1

[0064] see figure 1 , figure 1 It is a schematic flowchart of the multi-device wireless charging method provided by the first embodiment of the present invention. like figure 1 As shown, the multi-device wireless charging method includes:

[0065] S101, sensing whether there is a mobile device in the charging area of ​​the charging board;

[0066] S102. When sensing that there is a mobile device in the charging area of ​​the charging board, further determine whether there is a mobile device charging;

[0067] As an optional implementation manner, when it is sensed that there is a mobile device in the charging area of ​​the charging board, the step of further judging whether there is a mobile device charging also includes:

[0068] When it is determined that no mobile device is being charged, the charging board enters a sleep state.

[0069] S103, when it is judged that there is a mobile device charging, further judge whether there is a mobile device leaving the charging a...

Embodiment 2

[0086] see figure 2 , figure 2 It is a schematic flowchart of the multi-device wireless charging method provided by the second embodiment of the present invention.

[0087] S201, sensing whether there is a mobile device in the charging area of ​​the charging board;

[0088] S202. When it is sensed that there is a mobile device in the charging area of ​​the charging board, it is further judged whether there is a mobile device charging; when it is judged that there is no mobile device charging, go to step S209.

[0089] S203. When it is judged that there is a mobile device charging, further judge whether there is a mobile device leaving the charging area; when it is judged that there is a mobile device leaving the charging area, go to step S208.

[0090] S204, when it is judged that no mobile device has left the charging area, further judge whether it is a newly connected mobile device; if it is judged that it is not a newly connected mobile device, go to step S207.

Abstract

The invention provides a multi-device wireless charging method and system. The method comprises the following steps: sensing whether a charging zone of a charging board is provided with a mobile device; when sensing that the charging zone of the charging board is provided with the mobile device, further determining whether a mobile device is charged; when determining that the mobile device is charged, further determining whether the mobile device leaves the charging zone; when determining that no mobile device leaves the charging zone, further determining that whether a mobile device is newly accessed; and when determining that the mobile device is newly accessed, starting the charging initialization by virtue of the charging board, re-acquiring current data of the mobile device transmitted by virtue of Bluetooth, selecting a charging mode according to the acquired current data of the mobile device, providing a mobile device access charging form and a mobile device leaving charging form, and classifying a priority and different charging modes according to the current data of the mobile device transmitted by virtue of the Bluetooth.

Description

technical field [0001] The present invention relates to the technical field of magnetic resonance wireless charging, in particular to a multi-device wireless charging method and system. Background technique [0002] At present, wireless charging technology mainly includes four basic methods: electromagnetic induction, magnetic resonance, electric field coupling, and radio wave. At present, the most mature and common one is the electromagnetic induction type. Its technology is to apply the principle of electromagnetic induction. The alternating current flows through the transmitting coil to generate a changing magnetic field, and the transmitting coil generates current under the changing magnetic field to charge the receiving device. Magnetic resonance technology also applies the principle of electromagnetic induction, and the transmission and reception frequencies are the same to achieve a resonance effect to enhance transmission efficiency. The principle of electric field ...
