[0019] 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.

[0020] 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.

[0021] According to some embodiments, in the scheme of the present application, the smart door lock adopts geo-fencing technology to broadcast geo-fencing signals outward, wherein geo-fencing is a technology based on location services, which is commonly used in application scenarios such as automated control, location reminders, and security monitoring. The present application triggers specific actions when the device enters or leaves the area through a preset virtual area. The geo-fencing technology in the present application includes iBeacon or UWB (Ultra Wide Band), and accordingly, the broadcasted signal includes, for example, iBeacon signals or UWB signals. Among them, iBeacon is a BLE-based micro-positioning technology launched by Apple, which triggers the actions of nearby devices by continuously broadcasting specific signal packets. iBeacon technology is commonly used in application scenarios such as indoor positioning, push notifications, and automated control. UWB communication provides high-precision positioning services and can also confirm whether the mobile phone is inside or outside the door, and the cost is relatively high.

[0022] The mobile terminal scans the geo-fence signal broadcast by the smart door lock, and confirms whether the mobile terminal is in the preset area based on the scanned geo-fence signal. The preset area can be an area predetermined by a technician, or the range can be manually set. When the user enters the preset area or detects the iBeacon signal, the application (APP) corresponding to the smart door lock in the mobile phone is automatically triggered to start. In the process of starting the application, there is no need for manual operation by the user, which improves convenience.

[0023] According to some embodiments, after the application corresponding to the smart door lock is started, the wireless communication signal broadcast by the smart door lock is scanned, such as a BLE signal, a WiFi signal, etc. Among them, the smart door lock or other smart device corresponding to the application can be one or more. After scanning the wireless communication signal of the smart door lock, the identification information of the smart door lock, such as the UUID (Universally Unique Identifier) ​​of the smart door lock, is obtained through the wireless communication signal.

[0024] According to some embodiments, the mobile phone confirms the identity of the smart door lock through the identification information of the smart door lock to ensure security. 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] After the application recognizes the door lock identification information, it first checks whether it is currently connected to the door lock. If the connection is not established, the application actively sends a connection request to the communication module (such as the BLE module) of the door lock. If it is connected, the application directly performs identity authentication.

[0026] Send a communication connection request to the smart door lock, and establish a communication connection with the smart door lock, such as a BLE connection or a WiFi 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 a unique identifier of the user, that is, a 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, 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 functions (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 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.

[0028] When the identity information of the mobile phone is verified, the mobile phone sends an unlocking instruction to the smart door lock that is desired to be unlocked through the application, and the instruction is sent through the established communication connection. According to some embodiments, the unlocking instruction can be encrypted to ensure the security of instruction transmission.

[0029] After receiving the unlock command, the 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.

[0030] According to some embodiments, there is only one device under the application corresponding to the smart door lock, for example, there is only one smart door lock, and after the identification information of the door lock is obtained and a communication connection is established, an unlocking instruction can be sent to the device through the established communication connection. However, if there are multiple devices under the application corresponding to the smart door lock, for example, ten smart door locks, the application can obtain the identification information of the ten door locks respectively and establish a communication connection, but if an unlocking instruction is sent, it is not clear which smart door lock the unlocking instruction is for.

[0031] In this regard, according to one embodiment, a passive NFC tag can be set on the smart door lock, and the passive NFC tag stores the identification information of the smart door lock. The passive NFC tag can generally be attached to the smart door lock. The user approaches the door lock and places a mobile phone with NFC function close to the passive NFC tag of the door lock. When the mobile phone detects the NFC tag, the application automatically reads the identification information of the smart door lock in the NFC tag.

[0032] The application compares the first identification information of the smart door lock obtained by scanning the wireless communication broadcast with the second identification information of the smart door lock obtained by reading the NFC tag. If the two are the same, the application sends an unlock instruction to the smart door lock indicated by the first identification information. For example, if the identification information of ten smart door locks is obtained by scanning the wireless communication broadcast and the identification information of one smart door lock is obtained by reading the NFC tag, among the ten smart door locks, the application will only send an unlock instruction to the smart door lock whose identification information is the same as the identification information obtained by reading the NFC tag.

[0033] According to another embodiment, the user can operate on the interface of the application. For example, the application displays the current connections established with ten smart door locks and the information of each smart door lock (for example, name, identification information, etc.). The user can operate the application to determine the smart door lock that needs to be unlocked, and send confirmation information of the unlock instruction. The confirmation information includes the identification information of the smart door lock that needs to be unlocked, and then, the unlock instruction is sent to the smart door lock confirmed by the user.

[0034] Based on the above system, according to one aspect of the present application, a method for unlocking a smart door lock 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.

[0035] Step S201, scanning geo-fence signals broadcast by multiple smart door locks; Step S202, confirming whether the mobile terminal is located in a preset area according to the geo-fence signal; Step S203, in response to the mobile terminal being located in a preset area, starting the application programs corresponding to the multiple smart door locks.

[0036] According to some embodiments, in the scheme of the present application, the smart door lock adopts geo-fence technology to broadcast geo-fence signals to the outside, wherein geo-fence is a technology based on location services, which is commonly used in application scenarios such as automated control, location reminders, and security monitoring. The present application uses a preset virtual area to trigger specific actions when the device enters or leaves the area.

[0037] The mobile terminal scans the geo-fence signal broadcast by the smart door lock, and confirms whether the mobile terminal is in the preset area based on the scanned geo-fence signal. The preset area can be an area predetermined by a technician, or the range can be manually set. When the user enters the preset area or detects an iBeacon signal, the application corresponding to the smart door lock in the mobile phone is automatically triggered to start. In the process of starting the application, there is no need for manual operation by the user, which improves convenience.

[0038] Step S204, scanning the wireless communication signals broadcast by the multiple smart door locks to obtain multiple first identification information of the multiple smart door locks; Step S205, sending a communication connection request to the multiple smart door locks to establish a communication connection with the multiple smart door locks; Step S206, in response to detecting the passive NFC tag of the smart door lock, reading the second identification information of the smart door lock in the passive NFC tag through the application; Step 207: confirming the smart door lock indicated by the identification information that is the same as the second identification information among the multiple first identification information as the smart door lock that needs to be unlocked; and Step S208: Sending an unlocking instruction to the smart door lock that is confirmed to need to be unlocked via the established communication connection through the application.

[0039] According to some embodiments, after the application corresponding to the smart door lock is started, the wireless communication signal broadcast by the smart door lock is scanned, such as a BLE signal, a WiFi signal, etc. Among them, the smart door lock or other smart device corresponding to the application can be one or more. After scanning the wireless communication signal of the smart door lock, the identification information of the smart door lock, such as the UUID (Universally Unique Identifier) ​​of the smart door lock, is obtained through the wireless communication signal.

[0040] According to some embodiments, the mobile phone confirms the identity of the smart door lock through the identification information of the smart door lock to ensure security. 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.

[0041] A communication connection request is sent to the smart door lock to establish a communication connection with the smart door lock, such as a BLE connection or a WiFi 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 a unique identifier of the user, that is, a unique identifier of the user who owns the 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.

[0042] The smart door lock obtains the identity information of the mobile phone through the 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 unlocking instruction to the smart door lock that is desired to be unlocked through the application, and the instruction is sent through the established communication connection. According to some embodiments, the unlocking instruction can be encrypted to ensure the security of instruction transmission.

[0044] After receiving the unlock command, the 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.

[0045] According to some embodiments, there is only one device under the application corresponding to the smart door lock, for example, there is only one smart door lock, and after the identification information of the door lock is obtained and a communication connection is established, an unlocking instruction can be sent to the device through the established communication connection. However, if there are multiple devices under the application corresponding to the smart door lock, for example, ten smart door locks, the application can obtain the identification information of the ten door locks respectively and establish a communication connection, but if an unlocking instruction is sent, it is not clear which smart door lock the unlocking instruction is for.

[0046] In this regard, according to one embodiment, a passive NFC tag can be set on the smart door lock, and the passive NFC tag stores the identification information of the smart door lock. The passive NFC tag can generally be attached to the smart door lock. The user approaches the door lock and places a mobile phone with NFC function close to the passive NFC tag of the door lock. When the mobile phone detects the NFC tag, the application automatically reads the identification information of the smart door lock in the NFC tag.

[0047] The application compares the first identification information of the smart door lock obtained by scanning the wireless communication broadcast with the second identification information of the smart door lock obtained by reading the NFC tag. If the two are the same, the application sends an unlock instruction to the smart door lock indicated by the first identification information. For example, if the identification information of ten smart door locks is obtained by scanning the wireless communication broadcast and the identification information of one smart door lock is obtained by reading the NFC tag, among the ten smart door locks, the application will only send an unlock instruction to the smart door lock whose identification information is the same as the identification information obtained by reading the NFC tag.

[0048] According to another embodiment, the user can operate on the interface of the application. For example, the application displays the current connections established with ten smart door locks and the information of each smart door lock (for example, name, identification information, etc.). The user can operate the application to determine the smart door lock that needs to be unlocked, and send confirmation information of the unlock instruction. The confirmation information includes the identification information of the smart door lock that needs to be unlocked, and then, the unlock instruction is sent to the smart door lock confirmed by the user.

[0049] Based on the above system, according to another aspect of the present application, a method for unlocking a smart door lock is provided. Figure 3 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 3 As shown, the method includes the following steps.

[0050] Step S301, sending a geo-fence signal, the geo-fence signal enables the mobile terminal to confirm whether it is located in a preset area, so as to trigger the start of an application corresponding to the smart door lock on the mobile terminal; Step S302, receiving a communication connection request from the mobile terminal; Step S303, establishing a communication connection with the mobile terminal when the identity information of the mobile terminal is authenticated; Step S304, providing a passive NFC tag, wherein the passive NFC tag stores identification information of the smart door lock, so that the mobile terminal confirms the smart door lock that needs to be unlocked by reading the identification information; Step S305, receiving an unlocking instruction sent by the mobile terminal through the established communication connection; and Step S306: performing an unlocking operation according to the unlocking instruction.

[0051] According to some embodiments, after the application corresponding to the smart door lock is started, the wireless communication signal broadcast by the smart door lock, such as a BLE signal, a WiFi signal, etc., is scanned. Among them, the smart door lock or other smart device corresponding to the application can be one or more. After scanning the wireless communication signal of the smart door lock, the identification information of the smart door lock, such as the UUID of the smart door lock, is obtained through the wireless communication signal.

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.

[0054] The smart door lock obtains the identity information of the mobile phone through the 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.

[0055] When the identity information of the mobile phone is verified, the mobile phone sends an unlocking instruction to the smart door lock that is desired to be unlocked through the application, and the instruction is sent through the established communication connection. According to some embodiments, the unlocking instruction can be encrypted to ensure the security of instruction transmission.

[0056] After receiving the unlock command, the 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.

[0057] According to some embodiments, there is only one device under the application corresponding to the smart door lock, for example, there is only one smart door lock, and after the identification information of the door lock is obtained and a communication connection is established, an unlocking instruction can be sent to the device through the established communication connection.
