However, with the advancement of technology and changes in people's lifestyles, there are higher requirements for the convenience and intelligence of door locks.

[0003] For example, the publication number is CN106530465B, which discloses a low-power smart door lock and its implementation method, including a smart door lock and its response device and a cloud server, wherein the smart door lock is connected to a router, which is linked to the cloud server, and also includes a transfer box, which is linked to the smart door lock and the router. Since the transfer box is linked to the smart door lock, the smart door lock can be awakened by the transfer box, so that a low-frequency heartbeat packet can be used, thereby greatly reducing the power consumption of the smart door lock and extending the battery life.

[0004] However, the above-mentioned device is only a simple base station and does not cooperate with surrounding equipment to share videos, which affects the overall use effect. At the same time, during long-term use, due to the long-term use of the video recognition cat's eye of the smart door lock, the overall power consumption of the smart door lock is large, which affects the service life and requires frequent charging. Finally, this technology cannot provide the video interaction experience of the video door lock, and it is difficult to meet the user's demand for richer functions and good experience in actual usage scenarios.

[0046] The smart door lock module is connected to a cat's eye camera module, which provides camera recognition effect for the smart door lock module;

[0047] The wireless network video intercom module is connected to a human-shaped face algorithm information module, which is activated when the smart door lock module is triggered to detect whether there are people in various places in the room. The specific trigger content is: when there is someone inside the door, when someone outside the door rings the doorbell;

[0048] The wireless network video intercom modules are provided with multiple groups, which are usually matched with the number of rooms in the user's apartment, and each group of wireless network video intercom modules is separately provided with a human-shaped face algorithm information module for detecting people inside the room. The human-shaped face algorithm information module is connected to a volume detection module, and the volume detection module collects the human voice volume information in each room through the wireless network video intercom modules in each room, and transmits the collected information to the human-shaped face algorithm information module. When the human-shaped face algorithm information module fails to detect the presence of people in the room, the room with the largest human voice volume is selected according to the human voice volume information in different rooms provided by the above-mentioned volume detection module, and the wireless network video intercom module set in the corresponding room is started to ring, and the volume detection module is connected to the wireless network video intercom module.

[0049] The central processing module is connected to a remote control module, which transmits information from the smart door lock module, the wireless network camera module and the wireless network video intercom module to the user's mobile phone APP.

At the same time, when the human face algorithm information module detects that there are only elderly people and children in the room, after the remote control module transmits the video to the app, the video integration module integrates the images obtained by multiple groups of wireless network video intercom modules and smart door lock modules and wireless network camera modules into a panoramic home information, so that users can intuitively understand the comprehensive information of the family, and start the two-way audio and video communication capability of the wireless network video intercom module; S303. When there is an abnormality at the door, the indoor personnel turn on the video through the voice interaction function of the wireless network video intercom module, so that the wireless network video intercom module reads the image information outside the door collected by the wireless network camera module or the cat's eye video module through the communication module and displays it.
