In this step, one of the first device and the second device is a terminal device, and the other is a charging device, and the first device and the second device successfully shake hands, that is, the terminal device and the charging device successfully shake hands.

Among them, when the terminal device is located in the charging area of the charging device, the change of the magnet detected by the terminal device or the charging device can be used, and when the detected magnetic field change meets certain conditions, the terminal device and the charging device can be determined. The handshake is successful, that is, the terminal device is located in the preset area of the charging area. The distance between the terminal device and the charging area of the charging device can also be detected. For example, when the distance is less than a certain value, it can be determined that the terminal device and the charging device have successfully shaken hands.

Wherein, the first face feature information of the user, such as facial information, eye information, etc., may be collected by an image collector, such as a camera, etc., provided on the first device.

Step 402: If the first face feature information is successfully matched with the preset face feature information, control the first magnet to work with the first power.

In this step, the preset face feature information may be face feature information pre-stored by the owner of the terminal device. If the first face feature information is successfully matched with the preset face feature information, it can be shown that the terminal device is controlled by the owner. Then, the first magnet can be controlled to work with the first power, so that the first magnet has a magnetic adsorption force, and the second magnet arranged on the second device is magnetically adsorbed, and based on the principle of magnetic adsorption alignment, to The first device and the second device are adsorbed and aligned, and the first charging coil on the first device and the second charging coil on the second device are adsorbed and aligned, thereby improving the charging device's ability to the terminal device.

Wherein, when the power of the terminal device can be set to be the preset power, the power of the terminal device is just enough for the first magnet to perform a strong adsorption and alignment, and to achieve the alignment of the first charging coil and the second charging coil, so as to improve the performance of the terminal device. charging efficiency.

Wherein, when the power of the terminal device is lower than the preset power, it means that the remaining power of the terminal device is not enough to perform a strong adsorption alignment. At this time, the first magnet can be controlled to have a certain magnetic adsorption force by controlling the first magnet to work with the first power whose power is the first preset power value. Moreover, in this case, the charging device can also send the first information, the first information is used to indicate that the second magnet, which is the electromagnet, works with the power of the third preset power value, and by setting the third preset power value Set the power value to be greater than the first preset power value, that is, the second magnet generates a large magnetic adsorption force, so that a strong adsorption alignment is performed between the second magnet and the first magnet, so as to realize the first charging coil and the second magnet.

Optionally, during the adsorption alignment process of the first device and the second device, the adsorption alignment time of the first device and the second device can be set. For example, when the adsorption alignment time is set to 1 second, after the first magnet is controlled to work at the first current for 1 second, the adsorption alignment of the first device and the second device is determined, and then the adsorption current of the first magnet is reduced, In order to reduce the unit energy consumption of the first magnet during the charging process of the terminal device.

For example, when the first device and the second device are adsorbed and aligned, the magnitude of the working current required by the first magnet is I ₁ , and after the first device and the second device are adsorbed and aligned, the first magnet requires The magnitude of the working current is I ₂ , where I ₂ is smaller than I ₁ , thereby reducing the unit energy consumption of the first magnet during the charging process.

Optionally, the information interaction between the first device and the second device can be verified by QR code scanning, Bluetooth communication, WIFI communication, NFC communication, etc., as long as the information between the first device and the second device can be realized.
