[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0022] Figure 1 FIG. 1 is a schematic diagram of an unlocking system of a smart door lock according to an embodiment of the present application. Figure 1 As shown, the system includes a mobile terminal and a smart door lock. According to some implementations, the mobile terminal includes mobile devices such as mobile phones and tablet computers. For the convenience of expression and understanding, "mobile phone" is used below to represent the smart terminal, that is, the operations performed by the mobile phone can also be performed by other smart terminals. Smart door locks refer to locks that are improved on the basis of traditional mechanical locks and are more intelligent and simple in terms of user security, identification, and manageability. In the solution of the present application, a passive NFC tag is embedded on the surface of the smart door lock.

[0023] like Figure 1 As shown in the figure, the user approaches the door lock and places the NFC-enabled mobile phone close to the passive NFC tag of the door lock.

According to some embodiments, the identity information of the smart door lock includes the device code of the smart door lock. The mobile phone confirms the identity of the smart door lock through the read identity information of the smart door lock to ensure security.

[0025] According to some embodiments, if the identity confirmation of the smart door lock fails, the mobile phone will send a prompt message through the application to prompt the user and terminate the unlocking process.

[0026] According to some embodiments, if the identity of the smart door lock is successfully confirmed, the mobile phone sends a BLE connection request to the smart door lock. The BLE module of the smart door lock receives and confirms the connection request and establishes a BLE communication connection. After establishing a BLE connection with the smart door lock, the mobile phone sends the identity information of the mobile phone to the smart door lock through the application. According to one embodiment, the identity information of the mobile phone includes user login information, such as the user's unique identifier, that is, the unique identifier of the user who owns this door lock. According to some embodiments, before the identity information of the mobile phone is sent to the smart door lock through the application, the identity information of the mobile phone is encrypted, and the identity information sent to the smart door lock through the application is encrypted information. It can be understood by those skilled in the art that encryption can be performed in various formats, such as symmetric encryption (AES, DES), asymmetric encryption (RSA, ECC), hash function (MD5, SHA-1, SHA-256, SHA-512), etc., and this application does not make any limitation on this.

[0027] The smart door lock obtains the identity information of the mobile phone through the BLE connection and completes the authentication of the mobile phone. The verification process includes checking the user's identity information to ensure that only authorized users can unlock the door.

[0028] When the identity information of the mobile phone is verified, the mobile phone sends an unlocking instruction to the smart door lock through the application, and this instruction is sent through the BLE connection.

[0035] Step S203, when the identity information of the smart door lock is authenticated, a BLE connection request is sent to the smart door lock.

[0036] According to some embodiments, if the identity confirmation of the smart door lock is successful, the mobile phone sends a BLE connection request to the smart door lock. According to other embodiments, if the identity confirmation of the smart door lock fails, the mobile phone will send a prompt message through the application to prompt the user and terminate the unlocking process.

[0037] Step S204, after establishing a BLE connection with the smart door lock, sending the identity information of the mobile terminal to the smart door lock through the application.

[0038] According to some embodiments, the BLE module of the smart door lock receives and confirms the connection request and establishes a BLE communication connection. After establishing the BLE connection with the smart door lock, the mobile phone sends the identity information of the mobile phone to the smart door lock through the application. According to one embodiment, the identity information of the mobile phone includes user login information, such as the user's unique identifier, that is, the unique identifier of the user who owns this door lock. According to some embodiments, before sending the identity information of the mobile phone to the smart door lock through the application, the identity information of the mobile phone is encrypted.

[0039] Step S205: sending an unlocking instruction to the smart door lock via the BLE connection.

[0040] According to some embodiments, the smart door lock obtains the identity information of the mobile phone through the BLE connection to complete the identity authentication of the mobile phone. The verification process includes checking the user's identity information to ensure that only authorized users can unlock the door.

[0041] When the identity information of the mobile phone is verified, the mobile phone sends an unlocking instruction to the smart door lock through the application, and this instruction is sent through the BLE connection. According to some embodiments, the unlocking instruction can be encrypted to ensure the security of instruction transmission. After receiving the unlocking instruction, the door lock executes the unlocking operation to complete the unlocking.

[0042] Based on the above system, according to another aspect of the present application, a method for unlocking a smart door lock is provided. Figure 3FIG. 1 is a flow chart of a method for unlocking a smart door lock according to a smart door lock of an embodiment of the present application. Figure 3 As shown, the method includes the following steps.

[0045] Step S302: Establishing a BLE connection with the mobile terminal in response to a BLE connection request from the mobile terminal.

[0046] According to some embodiments, if the identity of the smart door lock is successfully confirmed, the mobile phone sends a BLE connection request to the smart door lock. The BLE module of the smart door lock receives and confirms the connection request and establishes a BLE communication connection.

[0047] Step S303: Acquire the identity information of the mobile terminal through the BLE connection.

[0048] According to some embodiments, after establishing a BLE connection with a smart door lock, the mobile phone sends the identity information of the mobile phone to the smart door lock through the application. According to one embodiment, the identity information of the mobile phone includes user login information, such as a unique identifier of the user, that is, a unique identifier of the user who owns the door lock. According to some embodiments, before sending the identity information of the mobile phone to the smart door lock through the application, the identity information of the mobile phone is encrypted.

[0049] Step S304, when the identity information of the mobile terminal is authenticated, receiving an unlocking instruction from the mobile terminal through the BLE connection; Step S305: performing an unlocking operation according to the unlocking instruction.

[0052] Among them, the passive NFC tag can be embedded in the surface of the smart door lock to store the identity information of the smart door lock and trigger the start of the application corresponding to the smart door lock in the mobile terminal. The BLE module is used to respond to the BLE connection request from the mobile terminal and establish a BLE connection with the mobile terminal; under the control of the main controller, the BLE module will actively communicate with the mobile terminal to transmit data and unlocking instructions. The main controller is the core processing unit of the door lock, responsible for receiving and processing data from the BLE module. The main controller is used to obtain the identity information of the mobile terminal through the BLE connection. When the identity information of the mobile terminal is authenticated, it receives the unlocking instruction from the mobile terminal through the BLE connection, and issues an unlocking control command according to the unlocking instruction. The motor drive module is responsible for driving the mechanical part of the smart door lock to lock or unlock. In response to the unlocking control command of the main controller, the motor drive module will issue an unlocking drive operation instruction to control the locking / unlocking mechanism. The locking / unlocking mechanism is the mechanical part of the door lock and is responsible for the actual locking and unlocking operations. In response to the unlocking drive operation instruction of the motor drive module, the locking / unlocking mechanism will perform corresponding mechanical actions to unlock or lock the door lock.
