Detailed ways

In order to enable those skilled in the art to better understand the solution of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation manners. the

Referring to Figure 1, it shows a flow chart of Embodiment 1 of the wireless charging method of the embodiment of the present invention, the method includes:

Step 101, a first wireless access point receives a charging request sent by a first device. the

In the wireless local area network, the terminal device and the wireless access point (English: access point, abbreviation: AP) communicate with each other through wireless signals. When the terminal device wants to perform wireless charging, it sends a charging request to the wireless access point. Here, the first device is a terminal device that sends a charging request to the wireless AP, and the first wireless access point refers to multiple wireless APs that receive the charging request sent by the first device. the

Step 102, the first wireless access point selects the beam pointing with the highest received signal strength from all the received signal beam points for the first device, and directs the first device according to the beam pointing with the highest received signal strength Performs wireless charging of the beamforming method. the

After the first wireless AP receives the charging request sent by the first device, it selects the best beam pointing according to the received signal strength of the first device, and the signal strengths received on different beam points are also different. Select the beam pointing with the highest received signal strength among the beam points of all received signals, and the first wireless AP performs wireless charging on the first device in a beamforming manner according to the selected beam pointing with the highest received signal strength. The beams pointing to the beamforming manner maximizes the strength of the signal reaching the first device. the

Step 103, the first wireless access point receives the association request sent by the second device, and sends the association request to the wireless access controller, so that the wireless access controller switches the first device to the second device. The channel of the wireless access point is used to accept wireless charging of the first device by the second wireless access point in a beamforming manner, wherein the channel of the second wireless access point is the same as that of the first wireless access point The channels of the points are different. the

When the first wireless AP wirelessly charges the first device, the second device sends an association request to the first wireless AP, indicating that the second device needs the first wireless AP to provide it with wireless communication services. The first wireless AP can provide wireless charging and wireless communication services for multiple devices. In the case that the capability of the first wireless AP is not enough to further provide wireless communication services for the second device while continuing to perform wireless charging for the first device, other wireless APs may be allowed to provide wireless communication services for the second device. However, preferably, in this embodiment of the present invention, the first wireless AP provides wireless communication services for the second device, and the first device is transferred to other wireless APs, and the other wireless APs continue to wirelessly charge the first device. In order to achieve the purpose of prioritizing the association request of the second device without affecting the charging process of the first device, the first wireless AP needs to be controlled by a wireless access controller (English: access controller, abbreviation: AC). The specific process is : The first wireless AP forwards the received association request sent by the second device to the wireless AC. Generally, adjacent wireless APs in the WLAN use different channels. Therefore, when the wireless AC receives the request, it needs to switch the first device from the channel of the first wireless AP to the channel of the second wireless AP. The second wireless AP selects the beam pointing with the highest received signal strength from all the beam points of the received signals, and performs wireless charging on the first device according to the beam pointing with the highest received signal strength, so that the first wireless AP is the second wireless AP. When the second device provides normal communication services, the charging process of the first device is not interrupted, and the first device is charged by the second wireless AP. the

As can be seen from the foregoing embodiments, the advantages of the embodiments of the present invention are:

After the first wireless AP receives the charging request sent by the first device, it selects the beam direction with the highest received signal strength from all the received signal beam directions for the first device, and uses the beam direction with the highest received signal strength for the The first device performs wireless charging in a beamforming manner. This charging manner ensures that the signal strength reaching the first device is the largest, and can improve wireless charging efficiency. At the same time, when the first wireless AP is charging the first device, the first wireless AP receives the charging request sent by the second device, and sends the association request to the wireless access controller, so that the wireless access controller The first device switches to the channel of the second wireless access point. Such a processing manner enables the first wireless AP to meet the wireless charging requirement of the first device while ensuring priority processing of communication services. the

Such a processing method can not only ensure that the first wireless AP can preferentially process the communication service, but also avoid affecting the charging efficiency of the first device due to the processing of the communication service by the first wireless AP. the

In order to better improve the efficiency of wireless charging, the embodiment of the present invention also provides a wireless charging method, see Figure 2, which shows the flow chart of Embodiment 2 of the wireless charging method of the embodiment of the present invention, the method includes:

Step 202, the first wireless access point selects the beam direction with the highest received signal strength from all the received signal beam directions for the first device, and directs the first device according to the beam direction with the highest received signal strength Performs wireless charging of the beamforming method. the

Step 203, the first wireless access point receives the association request sent by the second device, and sends the association request to the wireless access controller, so that the wireless access controller switches the first device to the second device. The channel of the wireless access point is used to accept wireless charging of the first device by the second wireless access point in a beamforming manner, wherein the channel of the second wireless access point is the same as that of the first wireless access point The channels of the points are different. the

Steps 201-203 are the same as steps 101-103, and will not be repeated here. the

In order to better improve the efficiency of wireless charging, in this embodiment, the wireless AC is used to control the third wireless access point to wirelessly charge the first device, as specifically shown in steps 204-205. the

Step 204, the third wireless access point receives the coordinate position sent by the wireless access controller, and the coordinate position is calculated by the wireless access controller according to the signal strengths sent by the at least three wireless access points. The coordinate position of the first device, the third wireless access point is a wireless access point other than at least three wireless access points that send received signal strength to the wireless access controller. the

In steps 201-203, the first wireless AP or the second wireless AP sends the received signal strength for the first device to the wireless AC. The signal strength can be the maximum signal strength received by the wireless AP, or it can be an omnidirectional beam. When the wireless AC receives the signal strengths sent by at least three wireless APs, the coordinate position of the first device may be calculated according to the signal strengths sent by the at least three wireless APs. For example, the wireless AC can select the signal strengths sent by three wireless APs from the received signal strengths, use the received signal strength to indicate the positioning algorithm to calculate the coordinate position of the first device, and then the wireless AC sends the calculated first device to the third wireless AP. The coordinate position of a device is used to instruct the third wireless AP to charge the first device. The third wireless AP is another wireless AP that is different from the first wireless AP and the second wireless AP in the network. the

Step 205, the third wireless access point adjusts the beam pointing according to the coordinate position, and performs wireless charging in a beamforming manner on the first device. the

When the third wireless AP receives the coordinate position of the first device sent by the wireless AC, it adjusts the beam to point to the coordinate position, that is, the third wireless AP adjusts the beam to point to the first device, so that the third wireless AP reaches the signal strength of the first device. maximum. the

On the basis of Embodiment 1 of the above-mentioned method, the wireless AC sends the coordinate position of the first device to the third wireless AP in the network, instructing the third wireless AP to adjust the beam pointing according to the coordinate position, and perform beam direction on the first device. Shaped wireless charging, so that the first device can receive signals sent by multiple wireless APs at the same time (for example: receive signals sent by the first wireless AP and the third wireless AP at the same time, or receive the signals sent by the second wireless AP and the third wireless AP at the same time The signal sent by the three wireless APs), therefore, can further improve its wireless charging efficiency. the

It should be noted that the third wireless AP may be specifically embodied as one wireless AP other than the first wireless AP and the second wireless AP, or multiple wireless APs other than the first wireless AP and the second wireless AP. the

In order to further improve the efficiency of wireless charging, on the basis of the above method embodiment 1 or embodiment 2, the method may also include:

On the basis of Embodiment 1 of the above method, the first wireless AP or the second wireless AP may obtain the medium access control (English: media access control, abbreviation: MAC) address of the first device, and send the MAC address to To the wireless AC, the wireless AP in the network that is not charging the first device is controlled by the wireless AC to associate with the first device according to the MAC address. According to the beam pointing with the highest received signal strength, wireless charging is performed on the first device in a beamforming manner. At this time, the wireless AP in the network controlled by the wireless AC that does not charge the first device is the other wireless AP in the network that is different from the first wireless AP and the second wireless AP. the

The beam with the highest intensity is directed to perform wireless charging in a beamforming manner on the first device.

For example: when the charging speed is lower than the preset charging speed, it means that the charging efficiency of the first device is too low to meet the wireless charging requirements of the device, and the charging efficiency needs to be improved to reduce the charging time. The charging wireless AP performs wireless charging to the first device according to a beamforming manner. Or, considering that the phase superposition of transmitted signals between different wireless APs may attenuate the signal reaching the first device, the wireless AC can also control some wireless APs that are wirelessly charging the first device to stop charging, so as to indirectly improve the charging efficiency. . the
