In this step, one of the first device and the second device is a terminal device, the other is a charging device, and the first device and the second device successfully handshake, that is, the terminal device and the charging device successfully handshake.
When the terminal device is located in the charging area of the charging device, the magnet change condition detected by the terminal device or the charging device can be used, and when the detected magnetic field change condition meets a certain condition, the handshake success between the terminal device and the charging device can be determined, namely 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 handshake between the terminal device and the charging device is successful.
The first unlocking information can be fingerprint information, face feature information, pupil information and the like. Fingerprint information of a user can be collected through a fingerprint module arranged on first equipment; or the face feature information or pupil information of the user is acquired through a camera arranged on the first device.
In this step, the unlocking information of the first device and the second device may be shared, and when the first unlocking information acquired by the first device fails to match with the second unlocking information stored in the first device, the third unlocking information stored in the second device may be acquired, so as to identify matching again. Therefore, the success rate of matching can be effectively improved.
For example, the first device is a charging device, the second device is a terminal device, fingerprint information stored on the charging device by the user is fingerprint information of a right index finger, and fingerprint information stored on the terminal device is fingerprint information of a left index finger; in the process of charging the terminal equipment, fingerprint information of a left index finger is used for unlocking, but the fingerprint information of a right index finger is stored in the charging equipment, so that unlocking identification is caused, and a user cannot charge; however, the user is the owner of the terminal device, and the user may not have a good charging experience due to the fact that the user forgets which finger the pre-stored fingerprint information is, which leads to charging failure.
Under the condition, the fingerprint information stored in the terminal equipment can be acquired and matched again, and if the matching is successful, the subsequent power charging process is executed, so that the charging experience of the user is improved.

The relative distance between the geometric center of the first charging coil and the first magnet is equal to the relative distance between the geometric center of the second charging coil and the second magnet, and the second magnet on the charging device is arranged corresponding to the position of the first magnet on the terminal device.
If the first unlocking information and the second unlocking information are successfully matched, the first magnet is also controlled to work at the first power, so that the first magnet generates a magnetic field and has magnetic adsorption force, magnetic adsorption is carried out on a second magnet arranged on the second equipment, and the first equipment and the second equipment are adsorbed and aligned on the basis of a magnetic adsorption alignment principle.
And step 404, after the first device and the second device are adsorbed and aligned, transmitting electric energy through the first charging coil so that the charging device charges a battery of the terminal device.
In the step, a first device is provided with a first charging coil, and a second device is provided with a second charging coil; if the first device is a terminal device and the second device is a charging device, the first charging coil can receive electric energy transmitted by the second charging coil, and a battery of the terminal device is charged; on the contrary, if the first device is a charging device and the second device is a terminal device, the electric energy can be transmitted to the second charging coil through the first charging coil so as to charge the battery of the terminal device.
Therefore, whether the charging operation of the terminal equipment is executed or not is determined by acquiring and identifying the unlocking information of the user, and the safety and the interactivity of the charging process can be effectively improved; and through adsorbing counterpoint with first magnet on the first equipment and the second magnet on the second equipment to make first charging coil on the first equipment aim at with the second charging coil on the second equipment, thereby improve charging equipment to terminal equipment's power transmission efficiency, and then improve the charge efficiency to terminal equipment.
Moreover, the unlocking information stored in the first device and the unlocking information stored in the second device are shared, so that the matching success rate of the unlocking information can be effectively improved, and the charging experience of a user is further improved.
Optionally, the obtaining third unlocking information stored in the second device includes: sending unlocking request information to the second equipment; and receiving third unlocking information sent by the second equipment, wherein the third unlocking information is extracted by the second equipment based on the unlocking request information.
In this embodiment, the unlocking information stored in the second device may be acquired by sending the unlocking request information.
One of the first device and the second device is a terminal device, and the other one is a charging device. The aim of bidirectional information sharing can be achieved by sharing the unlocking information stored by the charging equipment to the terminal equipment for unlocking recognition, or sharing the unlocking information stored by the terminal equipment to the charging equipment for unlocking recognition.
The method comprises the steps that for a terminal device with an unlocking function, after unlocking information on the charging device is identified and stored, and after the charging device collects the unlocking information again, the collected unlocking information is matched with the stored unlocking information. If the matching is successful, controlling the electromagnet of the charging equipment to work so as to generate larger magnetic force, carrying out magnetic adsorption on the terminal equipment, and simultaneously indicating that the light color of a second indicator lamp of the charging equipment changes; if the matching fails, the device serves as a device to send an instruction, the Bluetooth function of the device is awakened, meanwhile, the terminal device receives a magnetic field change induction signal of the charging device, the Bluetooth function of the device is also awakened, after the Bluetooth of the charging device and the Bluetooth of the terminal device are automatically matched successfully, the charging device can call unlocking information stored in the terminal device, if the collected unlocking information is successfully matched with the unlocking information of the terminal device, the electromagnet of the charging device is controlled to work, so that large magnetic force is generated, the terminal device is subjected to magnetic force adsorption, and meanwhile, the light color of a second indicator light of the charging device can be indicated to change.
Similarly, for the charging equipment with the unlocking function, after the unlocking information on the terminal equipment is identified and stored, and after the folding equipment collects the unlocking information again, the collected unlocking information is matched with the stored unlocking information. If the matching is successful, controlling an electromagnet of the terminal device to work so as to generate larger magnetic force, carrying out magnetic adsorption on the charging device, and simultaneously indicating that the light color of a first indicator lamp of the terminal device changes; if the matching fails, the terminal equipment sends an instruction to awaken the Bluetooth function of the terminal equipment, meanwhile, the charging equipment receives a magnetic field change induction signal of the terminal equipment and also awakens the Bluetooth function of the charging equipment, after the Bluetooth of the folding equipment and the Bluetooth of the charging equipment are automatically matched successfully, the terminal equipment can call unlocking information stored by the charging equipment, if the collected unlocking information is successfully matched with the unlocking information of the charging equipment, the electromagnet of the terminal equipment is controlled to work, so that larger magnetic force is generated, the charging equipment is subjected to magnetic adsorption, and meanwhile, the change of the light color of a first indicator lamp of the terminal equipment can be indicated.

Before the terminal device and the charging device perform handshake communication, unlocking information of the owner, such as fingerprint information or face feature information, can be stored on the charging device, and after the owner successfully stores the unlocking information, the second indicator lamp can emit light of a fourth color; then, when the charging device enters a state of starting to charge the terminal device, the light color of the second indicator light may be controlled to be converted from the fourth color to the first color, for example, yellow-charging to green-charging.
Optionally, after the indicator light of the first device is controlled to emit the light of the first color, the method further includes: acquiring fourth unlocking information acquired by the first equipment; if the fourth unlocking information is successfully matched with any one of the second unlocking information and the third unlocking information, interrupting the magnetic adsorption force between the first magnet and the second magnet, and controlling the light color of the indicator light to be converted from the first color to the second color; and if the fourth unlocking information is failed to be matched with the second unlocking information and the third unlocking information, increasing the magnetic adsorption force between the first magnet and the second magnet, and controlling the light color of the indicator light to be converted into a third color from the first color.
In this embodiment, fingerprint information or face feature information may be collected, and comparison and matching may be performed based on the collected fingerprint information or face feature information and pre-stored unlocking information (including pre-stored fingerprint information or pre-stored face feature information), and if matching is successful, it is determined that unlocking is successful; and if the matching fails, determining that the unlocking fails.
If the unlocking is successful, the power supply to the first magnet is interrupted, if the second magnet is also electrified, the power supply to the second magnet can be interrupted simultaneously, so that the magnetic adsorption force between the first magnet and the second magnet is relieved, and a user can take the terminal equipment away; if the unlocking is failed, the current unlocking object is determined to be not the owner of the terminal equipment, and at the moment, the magnetic adsorption force between the first magnet and the second magnet can be increased to prevent the non-owner user from taking away the terminal equipment.
When the unlocking is successful, the light color of the second indicator light can be controlled to be converted from the first color to the second color, for example, from yellow to blue, so as to remind the user that the magnetic attraction force between the terminal device and the charging device is relieved, and the user can take the terminal device away; in case of a failed unlocking, the light color of the second indicator light may be controlled to be switched from the first color to a third color, such as yellow-filled to red, to warn the non-owner user to prevent the terminal device from being taken away by the non-owner user. Through the setting of pilot lamp to according to the change of pilot lamp colour, can remind the specific state of user's battery charging outfit in the charging process, and promote user's the experience of charging.

Optionally, the preset times may be set to 2 times, 3 times, and the like, and the setting of the preset times may be set according to the habit of the user.
Therefore, the problem that the terminal equipment is taken away by a stranger in the charging process can be effectively solved by encrypting the charging equipment; moreover, through in the charging process, encryption and unlocking are added, and the operation experience of a user can be improved.
Optionally, the first device is a terminal device, the second device is a charging device, before the first magnet is controlled to operate at the first power, the electric quantity of the terminal device can be acquired, and the first power is controlled according to the electric quantity of the terminal device; if the electric quantity of the terminal equipment is detected to be lower than the preset electric quantity, the first magnet can be controlled to work at a higher power, and meanwhile, the first magnet of the terminal equipment is controlled to work at a lower power, so that the magnetic adsorption alignment of the first magnet and the second magnet is realized; if the detected electric quantity of the terminal equipment is higher than or equal to the preset electric quantity, the second magnet and the first magnet can be controlled to work at normal working power so as to meet the requirement of magnetic adsorption alignment of the first magnet and the second magnet. Therefore, the aim of aligning the first charging coil of the terminal device with the second charging coil of the charging device is fulfilled.
