[0037] Figure 3 This is a structural diagram of a preferred embodiment of the smart door lock of the present invention. DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, 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 used to limit the present invention.

[0039] The visitor identity confirmation method based on the smart door lock described in the preferred embodiment of the present invention is as follows: Figure 1 As shown, the visitor identity confirmation method based on the smart door lock includes the following steps:

[0040] Step S10: When it is detected that a visitor enters a temporary password through the input panel of the smart door lock, the camera of the smart door lock is activated to shoot the face of the visitor to obtain a facial image of the visitor.

[0041] Before step S10, it also includes: according to the user's setting operation instructions, a temporary password is set through the supporting mobile phone application of the smart door lock, and the valid time period for the visitor is selected; according to the sending method selected by the user, the temporary password is sent to the visitor. For example, a user (such as the owner of the house) sets a temporary password through the supporting mobile phone application (APP) of the smart door lock and selects the valid time period for the visitor. The user can choose the method of sending the password (such as SMS, email, etc.) and confirm that it is sent to the visitor's mobile phone. That is, when the visitor enters the temporary password and passes the face recognition verification, the system will immediately generate a notification content, which includes the visitor's facial image, name (if registered), entry time and status (such as "entered", "access denied", etc.). The system sends notifications through multiple channels, mainly including:

[0042] (1) Mobile APP push notifications: The APP installed on the user’s mobile phone will receive notifications in real time to ensure the timeliness of the information.

[0043] (2) SMS / email notification: If the user fails to check the APP in time, the system can also send notifications via SMS or email to ensure that the user does not miss important information.

[0044] Specifically, when the visitor arrives at the door, he enters the received temporary password through the input panel of the smart door lock. That is, when it is detected that the visitor enters the received temporary password through the input panel of the smart door lock within the valid time period, the temporary password is preliminarily verified; when the preliminary verification passes, the camera on the smart door lock is activated, and the visitor's facial image is captured by the camera to obtain the visitor's facial image.

[0045] Step S20, perform facial image processing on the visitor's facial image to extract key point features of the visitor's face. If it is determined that the visitor's facial image meets preset requirements based on the key point features, a notification that the visitor has entered, the visitor's facial image and the entry time are sent to the user.

[0046] Specifically, the system processes the captured image to ensure the image quality, that is, performs image clarity detection on the visitor's facial image to determine whether the visitor's facial image is clear. If it is blurred or incomplete, re-shoot the visitor's facial image, and try to shoot a clear and unobstructed visitor's facial image before the visitor opens the door to enter; performs occlusion detection on the visitor's facial image to check whether the visitor's facial image is obstructed. If it is obstructed, re-shoot the visitor's facial image to ensure that the facial features are completely visible; after the visitor's facial image is processed, extract the key point features of the visitor's face (such as eyes, nose, mouth, etc.), and judge the key point features according to preset requirements; if the visitor's facial image meets the preset requirements, wherein the preset requirements are that the image is clear and complete without obstruction, send a notification to the user's mobile phone APP to inform that the visitor has successfully entered, and attach the visitor's facial image and entry time, so that the user can view the visitor's related information through the mobile phone APP (that is, the user can choose to view the real-time video stream or historical records, so that the user can view the picture when the visitor enters in real time).

[0047] Step S30: When the smart door lock is unlocked, a linkage instruction is sent to the sweeping robot to control the sweeping robot to move to the door to take real-time pictures of the visitor, and send the captured pictures to the user in real time.

[0048] Specifically, the smart door lock establishes linkage control with the indoor sweeping robot in advance. The function of the linkage monitoring device is to realize all-round monitoring of visitors through the smart door lock and other monitoring devices (such as sweeping machines) to work together. This mechanism not only improves security, but also enhances the user's monitoring experience. The linkage device is controlled through a local area network or the cloud to ensure rapid response. The sweeping machine is equipped with a camera that can capture the image and video of the visitor in real time; when the smart door lock is detected to be unlocked, a linkage instruction is sent to the sweeping robot to control the sweeping robot to move to the door area; the sweeping robot receives the real-time picture of the visitor, and sends the captured picture to the user's mobile phone APP in real time to ensure that the user can understand the visitor's situation in real time. The video stream shot by the sweeping robot is encrypted and transmitted to the user's mobile phone APP, and the user can view the visitor's entry and exit in real time. Or when the smart door lock is detected to be unlocked, a linkage instruction is sent to the indoor camera to shoot the visitor, and the captured picture is sent to the user's mobile phone APP in real time.

[0049] If the user determines through the mobile phone APP that the visitor entering is abnormal, the user can conduct a two-way conversation through the sweeper, question the visitor, or take measures such as calling the police.

[0050] In addition, the visitor's entry and exit records, images and videos are saved to the cloud or stored locally. When the user's viewing instruction is detected, the user can view them at any time for security auditing. The system provides a playback function, and the user can select a specific time period to view the visitor's entry and exit records.

[0051] Users can view the real-time status of visitors in the APP. The interface includes: real-time video stream (if supported by camera), historical visitor records, visitor's image and identity information, and users can choose to operate on visitors, such as allowing entry, denying access or sending messages.

[0052] All notification information during the entire communication process uses encryption technology during transmission to ensure the security of user information and visitor identity, and to ensure that user privacy is not leaked. The system allows users to set privacy mode and turn off the monitoring function under certain circumstances. The system records the sending and receiving status of all notifications for subsequent review and tracking.

[0053] Through the above steps, the present invention can effectively improve the security and user experience of smart door locks, ensure accurate recording and real-time monitoring of visitor identities, improve the security of visitor identity confirmation, reduce the risk of unauthorized entry, and realize real-time monitoring. Users can instantly view visitor identities and entry situations, thereby enhancing the sense of family security.

[0054] For example, the user sets a temporary password for the visitor through the smart door lock APP and turns on the visitor monitoring function. When the visitor arrives at the door and enters the password, the camera starts and captures the visitor's facial image. The system sends the captured facial image to the user APP. The user views and confirms the visitor's identity through the APP. When the visitor completes the password input, the door lock opens according to the user's confirmation result.

[0055] For example, if the identity of a visitor cannot be verified, the system automatically links up with a sweeping robot. After receiving the command, the sweeping robot moves to the door and starts the camera to begin photographing the visitor. The sweeping robot transmits the captured images or videos to the user's APP, and the user monitors the visitor's behavior through the APP to further confirm the visitor's identity.

[0056] For example, the user sets a temporary password for the visitor through the smart door lock APP and turns on the visitor monitoring function. When the visitor arrives at the door and enters the password, the camera starts and captures the visitor's facial image. The system sends the captured facial image to the user APP. The user checks and confirms the visitor's identity through the APP. The visitor completes the password input and the door lock is opened according to the user's confirmation result. At the same time, the system controls the indoor smart camera to move to the door area and take pictures of the visitor. The images or videos taken by the indoor smart camera are transmitted to the user APP for real-time monitoring and confirmation by the user.

[0057] Furthermore, the user sets a temporary password for the visitor through the smart door lock APP and turns on the visitor monitoring function. When the visitor arrives at the door and enters the password, the camera starts and captures the visitor's facial image. The system sends the captured facial image to the user APP. The user checks and confirms the visitor's identity through the APP. The visitor completes the password input and the door lock is opened according to the user's confirmation result. At the same time, the system controls the indoor smart lighting adjustment system to light up the lights in the door area to provide visitors with a better lighting environment.

[0058] Furthermore, the user sets a temporary password for the visitor through the smart door lock APP and turns on the visitor monitoring function. When the visitor arrives at the door and enters the password, the camera starts and captures the visitor's facial image. The system sends the captured facial image to the user APP. The user checks and confirms the visitor's identity through the APP. After the visitor completes the password input, the door lock opens according to the user's confirmation result. At the same time, the system controls the indoor smart audio system to play music to welcome the visitor, creating a warm welcoming atmosphere.

[0059] That is, the system can be linked with a variety of monitoring devices, for example, smart cameras: provide higher quality video monitoring; smart home devices: automatically adjust the indoor environment (such as lighting, temperature, etc.) when visitors arrive. Each device communicates through a unified protocol to ensure smooth transmission of information.

[0060] The present invention uses a real-time notification and feedback mechanism to enable users to obtain visitor information in a timely manner, thereby enhancing safety and convenience. The linkage monitoring device provides a more comprehensive monitoring solution through the collaborative work of multiple devices, further improving the user experience.

[0061] Furthermore, if Figure 2 As shown, based on the above visitor identity confirmation method based on the smart door lock, the present invention also provides a visitor identity confirmation system based on the smart door lock, wherein the visitor identity confirmation system based on the smart door lock includes:

[0062] The image acquisition module 51 is used to activate the camera of the smart door lock to take a picture of the visitor's face and obtain a facial image of the visitor when it is detected that the visitor enters a temporary password through the input panel of the smart door lock;

[0063] The image verification module 52 is used to process the visitor's facial image and extract key features of the visitor's face. If the visitor's facial image is determined to meet preset requirements according to the key features, a notification of the visitor's entry, the visitor's facial image and the time of entry are sent to the user;

[0064] The real-time monitoring module 53 is used to send a linkage instruction to the sweeping robot when the smart door lock is unlocked, so as to control the sweeping robot to move to the door to take real-time pictures of the visitor, and send the taken pictures to the user in real time.
