Step S101: Obtain verification information indicating to unlock the access control;

Step S102: Establish a wireless communication connection with the mobile terminal according to the verification information;

Step S103: Based on the wireless communication connection, obtain the fingerprint information input by the user through the mobile terminal; and

Step S104: Determine whether the fingerprint information matches the pre-stored user fingerprint information, and if so, unlock the access control.

The method for unlocking the access control in this preferred embodiment will be described in detail below.

In steps S101 and S102, obtaining verification information indicating to unlock the access control includes: obtaining verification information indicating to unlock the access control from the mobile terminal, wherein the verification information includes identity verification information of the mobile terminal; according to the verification information and the mobile terminal Establishing a wireless communication connection includes: judging whether the identity verification information of the mobile terminal matches the pre-stored identity information, and if so, establishing a wireless communication connection with the mobile terminal.

The mobile terminal transmits verification information instructing to unlock the access control to the surroundings. After the access control obtains the verification information, it judges whether the identity verification information of the mobile terminal in the verification information matches the pre-stored identity information in the access control. If it matches, the access control and The mobile terminal establishes a wireless communication connection. If there is no match, the access control will ignore the verification information transmitted by the mobile terminal indicating to unlock the access control, that is, it will not establish a wireless communication connection with the mobile terminal. It can be understood that this method supports the user to actively search for matching access control through the mobile terminal, which increases the user's active experience and is more flexible and convenient in actual use.

Of course, the method of obtaining the verification information indicating to unlock the access control and establishing a wireless communication connection with the mobile terminal according to the verification information is not limited to the above-mentioned situation, and may also be:

Obtaining the verification information indicating to unlock the access control includes: obtaining the verification information indicating to unlock the access control locally, wherein the verification information includes local identity verification information; establishing a wireless communication connection with the mobile terminal according to the verification information, including: The terminal transmits local identity verification information, obtains a matching signal sent by the mobile terminal according to the local identity verification information, and establishes a wireless communication connection with the mobile terminal according to the matching signal.

After receiving the fingerprint matching failure signal, the mobile terminal prompts the user to re-input the fingerprint information and transmits the re-input fingerprint information to the access control. The access control obtains the fingerprint information input by the user again and performs Judging until the fingerprint information input by the user through the mobile terminal matches the pre-stored user fingerprint information.

In order to prevent the access control from being maliciously cracked, you can set the number of times the access control will reacquire the fingerprint information entered by the user through the mobile terminal within a certain period of time. For example, within 1 minute, if the access control reacquires the number of times If it exceeds 5 times, the access control will no longer perform the reacquisition action, and the user needs to open the access control through other methods, such as entering a password, opening with a key, and so on.

When multiple users use the same access control, the fingerprint information of multiple users can be stored in the access control, that is, the user fingerprint information of multiple users is stored in the access control. After the fingerprint information, judge whether the acquired fingerprint information matches one of the pre-stored user fingerprint information of multiple users, and if it matches, unlock the access control, so that multiple users can open the access control, improving the The practicality of access control applying the method.

After unlocking the access control, it also includes: transmitting a paging signal to the mobile terminal at a preset time interval, and if receiving a response signal fed back by the mobile terminal according to the paging signal within the preset time, then controlling the access control to remain in the unlocked state ; If the response signal fed back by the mobile terminal according to the paging signal is not received within the preset time, the access control is locked.

For example, every 30 seconds, the access control will transmit a paging signal to the mobile terminal. If the user is still within a certain range from the access control, the mobile terminal will receive the paging signal and feed back a response signal to the access control according to the paging signal. If the response signal is received within 5 seconds, the access control will remain unlocked; if the distance between the user and the access control exceeds a certain range, the mobile terminal will not receive the paging signal, that is, the access control will not be able to receive it within 5 seconds If the corresponding response signal is received, the access control will be locked. The method supports the access control to automatically determine whether the user is within a certain range, and realizes unlocking or locking the access control according to the judgment result without user intervention, bringing certain convenience to the user. Of course, in some occasions, even if the user is within a certain range from the access control, that is, the access control can receive the response signal fed back by the mobile terminal, but the user wants to lock the access control, the user can send a control signal to the access control through the mobile terminal, so that The door locks automatically.

The method provided in this preferred embodiment makes full use of the fingerprint sensor in the mobile terminal to collect the fingerprint information input by the user, so that the fingerprint sensor in the mobile terminal can be applied to both mobile terminal unlocking and access control unlocking.
