[0039] In order to make the purpose, technical solutions and advantages of the present invention more clear and distinct, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] The intelligent door lock control method based on face recognition and age determination described in the preferred embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, the smart door lock control method based on face recognition and age determination includes the following steps:

[0041] Step S10: When it is detected that the distance between a user and the smart door lock is within a preset range, the user's facial image is collected, and facial recognition is performed based on the facial image.

[0042] Specifically, when the smart door lock detects that the distance between the user and the smart door lock is within a preset range (for example, within 1 meter) (that is, when the smart door lock detects that a user is approaching), the smart door lock controls the camera to collect the user's facial image and performs facial recognition based on the facial image, that is, matches the collected facial image with the face pre-stored in the face database.

[0043] Step S20: If face recognition fails or the recognition result shows that the current user is not registered, determine whether the user is an elderly user based on the face image.

[0044] Specifically, after the smart door lock performs facial recognition based on the facial image, if facial recognition fails or the recognition result indicates that the current user is not registered (the current user may not have pre-entered the face into the face database), the smart door lock determines whether the user is an elderly user based on the facial image. For example, the user's age can be roughly determined by facial recognition. If the user is over a preset age (e.g., 60 years old), the user can be considered an elderly user. If facial recognition is successful, the smart door lock can be directly controlled to unlock.

[0045] If it is determined based on the facial image that the user is not an elderly user, the smart door lock is controlled to start the password input mode (i.e., the default mode), prompting the user to enter the password. When it is detected that the user has entered the password, the password is verified. If the password is correct, the smart door lock is controlled to unlock. If the password is incorrect, the smart door lock is controlled to prompt the user to re-enter the password. If it is detected that the number of incorrect password inputs exceeds a preset threshold (for example, 3 times), the smart door lock is controlled to lock within a preset time (for example, 1 hour) (the user outside the door may be a stranger at this time), and the management user of the smart door lock is remotely notified (for example, the door lock abnormality information is remotely sent to the management user's APP for reminder, and the management user is generally the owner of the house).

[0046] Step S30: If the user is an elderly user, the smart door lock is controlled to start the elderly-friendly mode, the password input interface is switched to a large-font password input interface, and a slow and clear voice is used to prompt the elderly user to enter a password on the large-font password input interface.

[0047] Specifically, if the user is judged to be an elderly user based on the facial image, the smart door lock is controlled to start the elderly-friendly mode (that is, the default mode is switched to the elderly-friendly mode), the password input interface is switched to the large-font password input interface (the large-font interface is convenient for the elderly to enter the password, and high contrast can also be used), and a slow and clear voice is used to prompt the elderly user to enter the password on the large-font password input interface. When it is detected that the elderly user has entered the password, the password is verified. If the password is correct, the smart door lock is controlled to unlock; if the password is incorrect, the smart door lock is controlled to prompt the elderly user to re-enter the password. If it is detected that the number of incorrect password inputs exceeds a preset threshold (for example, 3 times), the smart door lock is controlled to lock within a preset time (for example, lock for 1 hour), and the management user of the smart door lock is remotely notified.

[0048] Furthermore, if the password entered by the elderly user is incorrect, and it is detected that the accuracy rate of the numbers in the password entered by the elderly user is greater than a preset percentage (for example, the correct numbers out of 6 numbers are greater than 4), the smart door lock is controlled to remind the management user whether to unlock the door remotely. For example, face recognition fails due to obstruction or light, and the keys are entered incorrectly. However, if several of the numbers are entered correctly, the management user can be reminded. When the smart door lock receives the instruction to confirm remote unlocking, it controls the smart door lock to unlock remotely.

[0049] Furthermore, when it is detected that the smart door lock is unlocked and then remains in an unlocked state (for example, an elderly user forgets to lock the door after entering the house) for more than a predetermined time (for example, half an hour), the smart door lock voice reminds the elderly user and remotely notifies the management user of the smart door lock that there is a door lock abnormality.

[0050] like Figure 2 As shown in the figure, the control process of the entire smart door lock is as follows:

[0051] 1. Detect whether there is a user approaching the smart door lock;

[0052] 2. When a user is detected approaching the smart door lock, the user's facial image is collected;

[0053] 3. Performing face recognition based on the face image;

[0054] 4. Determine whether face recognition is successful;

[0055] 5. If the face recognition is successful, the smart door lock is directly controlled to unlock;

[0056] 6. If face recognition fails or the recognition result indicates that the current user is not registered, determine whether the user is an elderly user based on the face image;

[0057] 7. If the user is determined to be an elderly user based on the facial image, the smart door lock is controlled to start the elderly-friendly mode, the password input interface is switched to a large-font password input interface, and the elderly user is prompted to enter a password on the large-font password input interface;

[0058] 8. If it is determined based on the facial image that the user is not an elderly user, controlling the smart door lock to start a password input mode and prompting the user to enter a password;

[0059] 9. Password verification;

[0060] 10. After the elderly user enters the password, the password verification is performed. If the password is correct, the smart door lock is controlled to unlock; if the password is incorrect, the smart door lock is controlled to prompt the elderly user to re-enter the password;

[0061] When the user enters the password, the smart door lock is controlled to unlock if the password is correct; if the password is incorrect, the smart door lock is controlled to prompt the user to re-enter the password;

[0062] If it is detected that the number of incorrect password inputs exceeds a preset threshold, the smart door lock is controlled to be locked within a preset time, and the management user of the smart door lock is remotely notified.

[0063] Beneficial effects of the present invention:

[0064] (1) Improve the convenience of facial recognition authentication for elderly users;

[0065] (2) Through the failure compensation mechanism, the risk of the elderly being locked out due to recognition failure is reduced;

[0066] (3) Simplify the operation process for elderly users and improve safety and comfort;

[0067] (4) The family member’s remote assistance function ensures the safety of the elderly when entering the house.

[0068] Furthermore, if Figure 3 As shown, based on the above-mentioned smart door lock control method based on face recognition and age determination, the present invention also provides a smart door lock control system based on face recognition and age determination, wherein the smart door lock control system based on face recognition and age determination includes:

[0069] The face recognition module 51 is used to collect the user's face image and perform face recognition based on the face image when it is detected that the distance between the user and the smart door lock is within a preset range;

[0070] An age determination module 52 is configured to determine whether the user is an elderly user based on the facial image if face recognition fails or the recognition result indicates that the current user is not registered;

[0071] The mode control module 53 is used to control the smart door lock to start the elderly-friendly mode if the user is an elderly user, switch the password input interface to a large-font password input interface, and use a slow and clear voice to prompt the elderly user to enter a password on the large-font password input interface.

[0072] like Figure 4 As shown, the smart door lock (i.e., the smart door lock system) also includes a user interaction module, a remote management module, and an execution control module, wherein the mode control module is used to switch between the elderly-friendly mode and the default mode.

[0073] Furthermore, if Figure 5 As shown, based on the above-mentioned smart door lock control method and system based on face recognition and age determination, the present invention also provides a smart door lock, which includes a processor 10, a memory 20 and a display 30.
