[0020] 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.

[0021] 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 1As shown, the system includes a mobile terminal and a smart door lock, or includes a mobile terminal, a smart door lock and a gateway device. 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 to represent the smart terminal below, 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, an NFC tag is embedded on the surface of the smart door lock, which can be a passive NFC tag or an active NFC tag. The gateway device can be a Zigbee gateway or a Thread gateway, which is used to forward data or authentication information from the mobile terminal to the smart door lock.

[0022] According to some embodiments, the user's mobile phone writes the identity information of the smart door lock and the information for starting the application (APP) corresponding to the smart door lock into the NFC tag through a specific NFC writing application. The identity information of the smart door lock includes the device code of the smart door lock, such as UUID (Universally Unique Identifier) ​​or MAC (Media Access Control Address, Media Access Control Address), etc., and the information for starting the application corresponding to the smart door lock includes App URL and / or App schema (Android application record). If it is a passive NFC tag, it can generally be attached to the smart door lock.

[0023] like Figure 1 As shown, the user approaches the door lock and places the NFC-enabled mobile phone close to the NFC tag of the door lock. When the mobile phone detects the NFC tag, it automatically triggers the application corresponding to the smart door lock in the mobile phone to start. In the process of starting the application, the user does not need to operate manually, which improves convenience.

[0024] After the application is started, the mobile phone automatically reads the identity information of the smart door lock in the NFC tag. The mobile phone confirms the identity of the smart door lock through the read identity information of the smart door lock to ensure security. 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.

[0025] According to some embodiments, if the identity of the smart door lock is successfully confirmed, the mobile phone sends a communication connection request to the smart door lock, and the mobile phone and the smart door lock can establish a communication connection according to the corresponding communication protocol, and then exchange data through the communication protocol, which includes BLE protocol, WiFi protocol, ZigBee protocol and Thread protocol, etc. You can choose one of these communication protocols, or you can use a combination of these communication protocols.

[0026] Among them, the BLE protocol is used for short-range low-power communication. When the mobile phone approaches the smart door lock, a BLE connection is established, and identity authentication and data exchange are performed through BLE; for the WiFi protocol, it is suitable for WiFi protocol smart door locks. When the mobile phone approaches the smart door lock, a WiFi connection is established, and identity authentication and data exchange are performed through WiFi; for the ZigBee protocol or Thread protocol, when the mobile phone approaches the smart door lock, the identity authentication information is sent to the corresponding gateway, and the gateway forwards the identity authentication information to the smart door lock.

[0027] According to some embodiments, there are multiple authentication mechanisms between the mobile phone and the smart door lock to ensure that only authorized users can control the door lock, including user identity authentication and device authentication. Among them, user identity authentication means that the application corresponding to the smart door lock must be in the login state, and the user login requires identity authentication, such as password input, fingerprint recognition or face recognition, etc. At the same time, identity authentication is time-sensitive and the login status needs to be refreshed regularly; device authentication refers to device authentication between the mobile phone and the smart door lock to ensure that both communicating parties are trusted devices, including certificate verification and encryption channel establishment.

[0028] After establishing a communication 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. The smart door lock obtains the identity information of the mobile phone through the established communication connection and completes 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. Among them, the identity information of the mobile phone includes the user's unique identifier.

[0029] When the identity information of the mobile phone is verified, the mobile phone sends an unlock instruction to the smart door lock through the application, and the instruction is sent through the established communication connection. According to some embodiments, before sending the unlock instruction to the smart door lock through the communication connection, the unlock instruction can be encrypted to ensure the security of instruction transmission.

[0030] After receiving the unlock command, the smart door lock executes the unlock operation and completes the unlocking. The user can enter smoothly, and the entire unlocking process is fast, safe and convenient. After unlocking, the smart door lock system records all operation events to ensure traceability and management in the future, including operation logs. The smart door lock records the logs of each operation, including time, operation type and results, which is convenient for users to query and manage. At the same time, mobile phones can also record operation logs. In addition, the smart door lock also provides a feedback mechanism. After the operation is completed, the system provides feedback to the user, such as notifying the user through the mobile phone whether the unlocking is successful or failed.

[0031] In order to ensure that the user is within a reasonable physical range and further improve the security level of the unlocking process, according to some embodiments, before sending an unlocking command to the smart door lock through the established communication connection, the distance between the mobile phone and the smart door lock is measured, and the unlocking command is sent only when it is confirmed that the mobile phone and the smart door lock are within the preset range. According to some embodiments, both the mobile phone and the smart door lock can measure the distance between each other. The ways to measure the distance between the mobile phone and the smart door lock include UWB (Ultra Wide Band) communication, geo-fence technology, iBeacon, etc., and one of them can be selected or used in combination. Among them, UWB communication provides high-precision positioning services and can also confirm that the mobile phone is inside or outside the door; geo-fence can provide the approximate physical location of the mobile phone and the distance from the door lock; iBeacon is more accurate and the cost is more reasonable than UWB.

[0032] Through the unlocking system of the above-mentioned smart door lock, users only need to touch the NFC tag to quickly wake up the application and complete unlocking or other operations, which greatly improves the convenience of use, thereby improving the user experience; by using the active NFC function of the mobile phone, users no longer need to carry additional NFC cards, reducing the risk and inconvenience of losing the card; if the passive NFC solution is selected, the hardware manufacturer does not need to modify the lock body, and only needs to attach a passive NFC tag to implement this solution, which is low-cost; multiple authentication and multi-protocol communication ensure the high security of the system, prevent unauthorized access, and enhance security; the system supports common communication protocols and device types, has good compatibility and scalability, and strong compatibility. Through the above-mentioned system, while improving the convenience and security of smart door locks, it provides users with an efficient and flexible unlocking and control method, which has broad application prospects.

[0033] Based on the above system, according to one aspect of the present application, a method for unlocking a smart door lock implemented by a mobile terminal is provided. Figure 2 FIG. 1 is a flow chart of a method for unlocking a smart door lock implemented by a mobile terminal according to an embodiment of the present application. Figure 2 As shown, the method includes the following steps.

[0034] Step S201, in response to detecting the NFC tag of the smart door lock, starting an application corresponding to the smart door lock.

[0035] According to one embodiment, the user approaches the door lock and places a mobile phone with NFC function close to the NFC tag of the door lock. When the mobile phone detects the NFC tag, the application corresponding to the smart door lock in the mobile phone is automatically triggered to start. In the process of starting the application, the user does not need to operate manually, which improves convenience.

[0036] Step S202: read the identity information of the smart door lock in the NFC tag through the application.

[0037] After the application is started, the mobile phone automatically reads the identity information of the smart door lock in the NFC tag. 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.

[0038] Step S203, when the identity information of the smart door lock is authenticated, a communication connection request is sent to the smart door lock according to the identity information of the smart door lock.

[0039] According to some embodiments, if the identity of the smart door lock is successfully confirmed, the mobile phone sends a communication connection request to the smart door lock, and the mobile phone and the smart door lock can establish a communication connection according to the corresponding communication protocol, and then exchange data through the communication protocol, which includes BLE protocol, WiFi protocol, ZigBee protocol and Thread protocol, etc. You can choose one of these communication protocols, or you can use a combination of these communication protocols.

[0040] Among them, the BLE protocol is used for short-range low-power communication. When the mobile phone approaches the smart door lock, a BLE connection is established, and identity authentication and data exchange are performed through BLE; for the WiFi protocol, it is suitable for WiFi protocol smart door locks. When the mobile phone approaches the smart door lock, a WiFi connection is established, and identity authentication and data exchange are performed through WiFi; for the ZigBee protocol or Thread protocol, when the mobile phone approaches the smart door lock, the identity authentication information is sent to the corresponding gateway, and the gateway forwards the identity authentication information to the smart door lock.

[0041] Step S204, after establishing a communication connection with the smart door lock, sending the identity information of the mobile terminal to the smart door lock through the application; and Step S205, in response to the smart door lock authenticating the identity information of the mobile terminal, sending an unlocking instruction to the smart door lock through the communication connection.

[0042] After establishing a communication 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. The smart door lock obtains the identity information of the mobile phone through the established communication connection and completes 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.

[0043] When the identity information of the mobile phone is verified, the mobile phone sends an unlock instruction to the smart door lock through the application, and the instruction is sent through the established communication connection. According to some embodiments, before sending the unlock instruction to the smart door lock through the communication connection, the unlock instruction can be encrypted to ensure the security of instruction transmission.

[0044] Figure 3 FIG. 1 is a flow chart of a method for unlocking a smart door lock implemented by a mobile terminal according to another embodiment of the present application. Figure 2 compared to, Figure 3 Steps S301 to S305 of the method shown are Figure 2 The steps S201 to S205 are the same as above, except that: Figure 3 The method shown also includes: Step S306, before sending an unlocking instruction to the smart door lock through the communication connection, measuring the distance between the mobile terminal and the smart door lock.

[0045] In order to ensure that the user is within a reasonable physical range and further improve the security level of the unlocking process, according to some embodiments, before sending an unlocking command to the smart door lock through the established communication connection, the distance between the mobile phone and the smart door lock is measured, and the unlocking command is sent only when it is confirmed that the mobile phone and the smart door lock are within the preset range. According to some embodiments, both the mobile phone and the smart door lock can measure the distance between each other. Ways to measure the distance between the mobile phone and the smart door lock include UWB communication, geo-fence technology, iBeacon, etc., and you can choose one or use them in combination. Among them, UWB communication provides high-precision positioning services and can also confirm whether the mobile phone is inside or outside the door; geo-fences can provide the approximate physical location of the mobile phone and the distance from the door lock; iBeacon is more accurate and the cost is more reasonable than UWB.

[0046] Thus, step S305 may specifically include: When the distance between the mobile terminal and the smart door lock is within a preset range, an unlocking instruction is sent to the smart door lock through the communication connection.

[0047] According to another aspect of the present application, a method for unlocking a smart door lock implemented by a smart door lock is provided. Figure 4 FIG. 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 4 As shown, the method includes the following steps.

[0048] Step S401, providing an NFC tag, wherein the NFC tag is used to trigger the start of an application corresponding to the smart door lock on the mobile terminal.

[0049] According to one embodiment, the NFC tag can be a passive NFC tag or an active NFC tag. If it is a passive NFC tag, it can generally be attached to the smart door lock. The user approaches the door lock and brings a mobile phone with NFC function close to the NFC tag of the door lock. When the mobile phone detects the NFC tag, it automatically triggers the start of the application corresponding to the smart door lock in the mobile phone.

[0050] Step S402: Establishing a communication connection with the mobile terminal in response to a communication connection request from the mobile terminal.

[0051] According to some embodiments, if the identity of the smart door lock is successfully confirmed, the mobile phone sends a communication connection request to the smart door lock, and the mobile phone and the smart door lock can establish a communication connection according to the corresponding communication protocol, and then exchange data through the communication protocol, which includes BLE protocol, WiFi protocol, ZigBee protocol and Thread protocol, etc. You can choose one of these communication protocols, or you can use a combination of these communication protocols.

[0052] Step S403, obtaining identity information of the mobile terminal through the communication connection; Step S404, when the identity information of the mobile terminal is authenticated, receiving an unlocking instruction from the mobile terminal through the communication connection; and Step S405: performing an unlocking operation according to the unlocking instruction.

[0053] After establishing a communication 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. The smart door lock obtains the identity information of the mobile phone through the established communication connection and completes 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. Among them, the identity information of the mobile phone includes the user's unique identifier.

[0054] When the identity information of the mobile phone is verified, the mobile phone sends an unlock instruction to the smart door lock through the application, and the instruction is sent through the established communication connection. According to some embodiments, before sending the unlock instruction to the smart door lock through the communication connection, the unlock instruction can be encrypted to ensure the security of instruction transmission.

[0055] After receiving the unlock command, the smart door lock executes the unlock operation and completes the unlocking. The user can enter smoothly, and the entire unlocking process is fast, safe and convenient.

[0056] Figure 4 1 is a flow chart of an unlocking method of a smart door lock implemented by a smart door lock according to another embodiment of the present application. Figure 4 compared to, Figure 5Steps S501 to S505 of the method shown are Figure 4 The steps S401 to S405 are the same as above, except that: Figure 5 The method shown also includes: Step S506, before performing the unlocking operation according to the unlocking instruction, measuring the distance between the smart door lock and the mobile terminal.

[0057] In order to ensure that the user is within a reasonable physical range and further improve the safety level of the unlocking process, according to some embodiments, before sending an unlocking command to the smart door lock through the established communication connection, the distance between the mobile phone and the smart door lock is measured, and the unlocking command is sent only when it is confirmed that the mobile phone and the smart door lock are within a preset range. According to some embodiments, both the mobile phone and the smart door lock can measure the distance between each other. Ways to measure the distance between the mobile phone and the smart door lock include UWB communication, geo-fencing technology, iBeacon, etc., and you can choose one or use a combination.

[0058] According to the smart door lock and its unlocking method and system provided by the present application, the mobile terminal can complete the verification of the smart door lock by reading the NFC tag of the smart door lock, establish a communication connection with the smart door lock through other wireless communication technologies, and issue an unlocking instruction through the established communication connection, thereby realizing the unlocking control of the smart door lock.
