[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] A screenless, networked facial recognition lock includes a server for storing user identity data and a door lock installed on a residential door. It further includes: a data acquisition module 1 for collecting user identity data when the user approaches a predetermined location; a main control chip module 2 for issuing a first identity signal when the identity data collected by the data acquisition module 1 matches the identity data stored in the server, and otherwise issuing a second identity signal, and sending the identity data collected by the data acquisition module 1 to the server; a lock control module 3 for controlling the door lock to open the residential door when the main control chip module 2 issues the first identity signal; and a network communication module 4 for establishing signal communication between the main control chip module 2 and the server. The network communication module 4 enables data interaction with the server and can be a 4G module, etc., which will not be elaborated further. First, the user inputs their identity information into the server. For example, when checking into a hotel, the user inputs their information through a hotel booking platform and completes the check-in process. The system binds a user's identity information to a specific room. When a user approaches the door of that room, the data acquisition module 1 collects the user's face in real time to obtain identity data. This identity data is then transmitted to the server via the network communication module 4. When the identity data matches the facial data stored on the server, a first identity signal is emitted, causing the lock control module 3 to open the door. Therefore, the lock control module 3 requires two conditions to open the door: first, the user's identity data must be stored on the server; second, the door opened by the user must match the door bound to the identity data in the server. This prevents unauthorized access to the door, ensuring user safety. Furthermore, even if someone follows the homeowner into the room, the data acquisition module 1 will collect their facial data when they approach the designated location. This allows the homeowner to be alerted or the facial data to be saved to the server, ensuring the traceability of the follower and protecting user safety from multiple angles.

[0030] The circuit structure of the main control chip module 2 is described in detail below. The main control chip module 2 includes chip U7, which is used to process identity data and interact with the server, as well as issue commands to control the action of the lock control module 3. Chip U5 is connected to chip U7, which is used to store firmware programs and face recognition logs.

[0031] The circuit structure of the data acquisition module 1 is described in detail below. The data acquisition module 1 includes a chip J3 connected to the main control chip module 2 for connecting to the camera. Electrostatic protectors E1 and E2 are connected between pin 1, pin 2, and pin 3 of the chip J3 to prevent the camera and the chip J3 from being damaged by electrostatic discharge.

[0032] To further enrich the diversity of data acquisition methods in the data acquisition module 1, the data acquisition module 1 also includes a chip J5 for connecting to the fingerprint acquisition device. Pins 1 and 2 of the chip J5 are connected in sequence to the main control chip module 2 via an electrostatic discharge protector Z1, a capacitor C21, and a MOSFET Q4. The capacitor C21 performs power filtering to ensure the stability of the MOSFET during switching. The MOSFET Q4 acts as a power switch in the circuit, and its conduction state is controlled by the main control chip module 2 through the FP_EN signal, thereby managing the power supply of the face recognition module (such as turning the module power on / off) to achieve low-power design and modular power management.

[0033] The circuit structure of the lock control module 3 is described in detail below. The lock control module 3 includes a chip U4 connected to the main control chip module 2. This chip is a motor drive chip that controls the opening and closing of the door lock. A capacitor E3 is connected between pin 4, pin 6, and pin 7 of chip U4. A chip J6 is connected between pins 5 and 8. A capacitor C69 is connected between chip U4 and chip J6. A grounded capacitor C13 and a capacitor C14 are connected in parallel on pin 1 of chip U4.

[0034] To facilitate the precise operation of the lock control module 3 and the monitoring of the door lock status, the lock control module 3 also includes a chip J4. The chip J4 is connected to a sensor for monitoring the opening and closing status of the electronic lock. The grounded electrostatic discharge protector Z12 and electrostatic discharge protector Z13 are connected to pins 2 and 3 of the chip J4, respectively.

[0035] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
