Embodiment 1

[0064] see figure 1 , is a schematic flowchart of an automatic matching method between wireless charging devices provided in Embodiment 1 of the present invention. The wireless charging device includes a wireless charging transmitter and a receiver, and both the transmitter and the receiver transmit data through a wireless radio frequency module. communication, the method includes the steps of:

[0065] Step S10, the receiving end obtains an idle transmitting end.

[0066] After the wireless charging car installed with the receiving end enters the charging area, the receiving end obtains all the idle transmitters in the charging area, so as to select the target transmitter from the idle transmitters and realize the matching between the receiving end and the transmitting end.

[0067] Wherein, the wireless radio frequency modules of the receiving end that has just entered the charging area and the idle transmitting end both use a common address as the communication address.

Embodiment 2

[0085] see image 3 , is a schematic flowchart of an automatic matching method between wireless charging devices provided in Embodiment 2 of the present invention. The difference between Embodiment 2 and Embodiment 1 is that after step S50 in Embodiment 1, the method further includes:

[0086] Step S60, sending a private address test command to the target transmitting end through the private address.

[0087] Step S70, judging whether a reply message based on the private address test command from the target transmitter is received.

[0088] Step S80, if a reply message from the target transmitter based on the private address test command is received, receive the wireless power transmission of the target transmitter.

[0089] Step S90, if the reply information based on the private address test command from the target transmitter is not received, change the communication address of the wireless radio frequency module to the common address, and return to step S10, that is, the r...

Embodiment 3

[0095] see Figure 4 , is a schematic structural diagram of an automatic matching device between wireless charging devices provided in the second embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown. The wireless charging device includes a wireless charging transmitting end and a receiving end, and the transmitting end and the receiving end both perform data communication through a wireless radio frequency module, and the automatic matching device between the wireless charging devices includes:

[0096] The idle transmitting end obtaining unit 10 is used for the receiving end to obtain an idle transmitting end.

[0097] The idle transmitter acquisition unit 10 includes: a scanning transmitter command sending module, which is used for the receiving terminal to control the wireless radio frequency module to send a scan transmitter command through a common address;

[0098] An idle tr...

Abstract

The invention provides an automatic matching method and device between wireless charging devices and a storage medium. Each wireless charging device comprises a transmitting end and a receiving end for wireless charging, the transmitting end and the receiving end perform data communication through a wireless radio frequency module, and the method comprises the following steps: acquiring an idle transmitting end; sending a wireless power transmission time sequence to the target transmitting end; after detecting the electric energy transmitted according to the wireless electric energy transmission time sequence and establishing communication with the target transmitting end, calculating a private address according to the equipment information of the receiving end and the target transmittingend, and taking the private address as a communication address of the receiving end and the target transmitting end; and performing data communication through the private address. An additional wireless communication module capable of networking is not needed, and one-to-one automatic matching is realized by changing the communication address of the wireless radio frequency module. Communication interference in a public area is overcome by adopting the transmitting end and the receiving end which are communicated through the private address, and data transmission errors in the wireless charging process are avoided.

Description

technical field [0001] The present invention relates to the technical field of wireless charging, in particular to an automatic matching method, device and storage medium between wireless charging devices. Background technique [0002] With the development of technology, wireless charging devices are widely used. A wireless charging system is generally divided into a transmitter and a receiver. Because the two parties are non-contact when working, they can only exchange data by means of wireless communication. [0003] At present, many wireless charging devices use low-cost radio frequency communication modules to achieve communication, such as 433M HZ, 2.4G HZ communication modules. The communication between the transmitting end and the receiving end is realized by controlling the radio frequency communication module through the MCU. Wireless charging data transmission is realized by means of radio frequency communication, which has the advantages of low cost and easy te...
