AI Technical Summary

Problems solved by technology

However, in the application scenario of multiple sets of wireless charging devices, only one transmitter can be fixed to pair with one receiver
Fixing one transmitter corresponds to fixing one receiver. This combination leads to low utilization of the transmitter, especially when there are more devices installed with the wireless charging system, the more transmitters will increase, which increases the purchase cost and equipment installation. Second, whenever the device needs to be charged, it is necessary to find a fixed corresponding transmitter instead of nearby charging, which increases the complexity of the charging process of the system

[0033] Such as figure 1 As shown, a first embodiment of a method for pairing a transmitter and a receiver in a wireless charging scenario includes the following steps:

[0034] S101, the receiving end broadcasts charging requirements to multiple transmitting ends;

[0035] S102. The receiving end receives feedback results from a plurality of transmitting ends according to the charging requirement, and the feedback results include PWM waveforms;

[0036] S103, the receiving end determines the nearest transmitting end according to the PWM waveform, and obtains the local address of the nearby transmitting end;

[0037] S104, the receiving end uses the local address of the nearest transmitting end as its own destination address;

[0038] S105, the receiving end broadcasts its own local address to the nearest transmitting end to complete the pairing.

[0039] In this embodiment, no additional sensors and hardware devices are required. Use the coil and wireless communication mod...

[0041] Such as figure 2 As shown, a second embodiment of a method for pairing a transmitter and a receiver in a wireless charging scenario includes the following steps:

[0042] S201, the receiving end broadcasts charging requirements to multiple transmitting ends.

[0043] Specifically, the wireless communication module I at the transmitting end has a local address I and the destination address I, and the wireless communication module II at the receiving end has a local address II and a destination address II. The local address I of each transmitting end is a specific value defined manually, namely local address Ⅰ 1 , local address I 2 , ..., local address I N . Similarly, the local address II of each receiver is also a specific value defined by humans, that is, the local address II 1 , local address II 2 ,...,local address II N . What needs to be explained is that since the local address I and the local address II are defined artificially, there is no limitation her...

Abstract

The invention relates to the field of wireless charging and discloses a pairing method and a paring system of a transmitting end and a receiving end under a wireless charging scene, wherein the methodcomprises the following steps: the receiving end broadcasts a charging requirement to a plurality of the transmitting ends; the receiving end receives a result of feedback of the plurality of transmitting ends according to the charging requirement, and the result of feedback comprises PWM waveform; the receiving end determines the transmitting end nearby according to the PWM waveform and obtainsa local address of the transmitting end nearby; the receiving end takes the local address of the transmitting end nearby as an own destination address; and the receiving end transmits the own local address to the transmitting end through unicast to complete paring. According to the method and the system provided by the invention, additional sensors and hardware devices are not needed, own coils and wireless communication modules of a wireless charging device are used, and pairing is executed nearby before charging of the wireless charging device. Utilization rate of the transmitting end of thewireless charging device is improved, device procurement cost is reduced, device mounting area is decreased, time for finding a unique transmitting end position before charging is reduced, and charging efficiency is improved.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a pairing method and system for a transmitter and a receiver in a wireless charging scenario. Background technique [0002] At present, wireless charging uses radio wave and electromagnetic induction technology to generate current through the induction of the coil in the transmitting end and the coil in the receiving end, and convert the induced current into an electromagnetic wave signal, and the electromagnetic wave signal is transmitted from the transmitting end to the receiving end. The receiving device at the receiving end converts the received electromagnetic wave signal into a DC power source used by the receiving end, thereby realizing charging. However, in the application scenario of multiple wireless charging devices, only one transmitter can be fixed to pair with one receiver. Fixing one transmitter corresponds to fixing one receiver. This combination leads to low uti...
