The RTC clock chip 321 and the button battery 322 can form a first power module, which is used to provide working power to the main chip module.

[0072] In this embodiment of the disclosure, the video module 100 serves as the image acquisition unit of the smart door lock and can be used for acquiring video images, such as... Figure 1 As shown, the video module 100 may specifically include the following main components or modules: video main control chip 101; EMMC (optional) 102; storage chip (flash memory, FLASH) 103; programming interface 104; infrared LED module consisting of infrared LED 105 and LED driver 106; camera IR-Cut 107; IR_CUT driver 108; camera module 109; microphone 110; photosensor 111; USB switch 113; production test port 114; programming interface 115; multi-channel switch chip 117; OTA-UART 118; and infrared lamp mutual exclusion signal 119.

It is the core computing unit of the video module 100. For example, it can be used to control the camera module to collect image information in front of the door and to control the sound acquisition module to collect sound information in front of the door. The camera module may include a camera IR-Cut 107, an IR_CUT driver 108, and a camera module 109. The sound acquisition module may include a microphone 110.

[0074] In specific application scenarios, as a preferred method, such as Figure 1As shown, both the camera module 109 and the 3D face recognition and palm vein recognition module 302 use 940nm wavelength infrared lights for illumination. Therefore, the infrared illumination times of the camera module 109 and the 3D face recognition and palm vein recognition module 302 need to be mutually exclusive, and a mutual exclusion signal line is used for communication between the two modules. Accordingly, the camera module 109 and the 3D face recognition and palm vein recognition module 302 are connected via a mutual exclusion signal line, which is used to transmit the mutual exclusion time signal for the infrared illumination of the camera module 109 and the 3D face recognition and palm vein recognition module 302.

The power system 416 provides power to the rear panel control system 2 and can be controlled by the main chip to control the switching of related power supplies so that the rear panel control system 2 enters low power consumption mode.

[0080] The display module 500 serves as the display unit of the smart door lock, providing image display functionality to the rear panel control system 2. For example... Figure 1 As shown, it includes the following main components and / or modules: screen chip 501; debug port 502; SPI FLASH memory chip 503; display screen 504; backlight driver 505; display screen backlight 506.

[0081] The screen chip 501 is a CPU that serves as an image display interface. It has a USB interface, which can act as a SLAVE to receive video streams output from the "101-Video Master Control Chip". It supports RGB or MIPI-DSI interfaces for connecting an external LCD display, and can also connect to the 101 video master control chip to drive the display to show the door-viewing image information sent by the video master control chip. It also has an external SPI-Flash storage chip expansion interface for storing local display content. The debug port 502 can be used for R&D debugging or firmware upgrades; the SPI FLASH storage chip 503 can be used to store relevant logos or icons that need to be displayed.

[0082] In specific application scenarios, the door lock system is powered by a lithium battery and maintains a low-power state by default to extend the system's operating time. In this low-power state, the WIFI module 201 and the PIR human infrared proximity sensor 202 of the WIFI module 200 operate in a low-power mode. When maintaining a low-power state by default, the following components on the front panel—ultrasonic sensor module 305, finger vein or fingerprint module 306, button module 311, smart card module 313, doorbell button 324, anti-tamper switch 315, USB insertion detection circuit 317, and main chip 301—are all in a low-power operating state, awaiting event input to wake up the entire system.

[0083] like Figure 3 The embodiments of this disclosure provide a control method for a door lock system, including:

[0084] Step 601: Use the ultrasonic sensor module to detect obstacle information in front of the door lock.

[0085] Step 602: When it is determined that someone is approaching based on obstacle information, the biometric module is used to perform unlocking authentication and the unlocking authentication result is sent to the control module so that the control module can perform unlocking control on the lock body according to the unlocking authentication result.

[0086] The biometric module includes at least two acquisition devices, such as 3D face recognition and palm vein recognition modules, finger vein modules or fingerprint modules, button modules, smart card modules, etc. The at least two acquisition devices in the biometric module are used to collect different biometric features respectively.

[0087] In the embodiments of this disclosure, one possible implementation for controlling the door lock system is as follows: Figure 4As shown, a door lock control system can be provided with control logic 1---door opening via an external "two-in-one module, namely a 3D face recognition and palm vein recognition module". This door lock control system includes a main chip module 300 and a rear panel module 400. Specifically: the user pre-configures the smart door lock APP to support 3D face recognition or palm vein recognition unlocking. When the user approaches the door with the door lock system installed at approximately 1 meter, the "305-ultrasonic sensor module", operating in a low-power state, detects... When a human approaches, the "305-ultrasonic sensor module" outputs an interrupt to the "301-main chip," which wakes up the entire system. The "301-main chip" then powers on the two-in-one module, activating the corresponding face module or palm vein module. The corresponding module completes detection and recognition. If authentication is successful, the "400-Bluetooth rear panel module" controls the "413-motor driver" to drive the "414-motor" and "415-lock body" to unlock. If authentication fails, re-detection or timeout management is performed. After unlocking, the two-in-one module powers off, and the system enters low-power standby mode.

[0088] Correspondingly, as another possible implementation method for controlling the door lock system, a control logic 2 for the door lock control system can be provided. This door lock control system includes a main chip module 300 and a rear panel module 400. Specifically, for unlocking via other authentication modules outside the door: the user pre-configures the smart door lock APP control terminal to not support 3D face recognition or palm vein recognition unlocking, and the "305-ultrasonic sensor module" does not work. When the user approaches the door, the "two-in-one module" is not activated; the user unlocks the door using other unlocking methods on the front panel. These other unlocking methods include using modules such as "306-finger vein module or fingerprint module," "311-button module," and "313-smart card module" to input a password. After authentication, the "400-Bluetooth rear panel module" controls "413-motor drive" to drive "414-motor" and "415-lock body" to unlock. If authentication fails, a re-test or timeout management is performed. After the unlocking action is completed, the system enters a low-power standby state.

[0089] Furthermore, when controlling a door lock system, one possible implementation method is, such as Figure 5As shown, a control logic 3 for a door lock control system can be provided. This door lock control system includes a main chip module 300 and a rear panel module 400. Specifically, for ETOUCH unlocking from inside the door: the user unlocks the door by touching the "404-ETOUCH button *2 (unlock button)" on the "400-Bluetooth rear panel module". After authentication, the "400-Bluetooth rear panel module" controls the "413-motor drive" to drive the "414-motor" and "415-lock body" to unlock. After the unlocking action is completed, the system enters a low-power standby state. Correspondingly, the implementation steps may include: receiving unlocking information uploaded by the user through the unlock button in the rear panel control system; after the unlocking information is approved, using the motor module in the rear panel control system to drive the lock body to unlock.

[0090] In specific application scenarios, when controlling a door lock system, one possible implementation method is... Figure 6As shown, a working logic for a video system can also be provided. This video system includes a video module 100, a WIFI module 200, and a display module 500. Specifically: When someone passes by the door: When a user approaches the door with the door lock system approximately 3 meters away, the "202-PIR Human Infrared Proximity Sensor," operating in a low-power state, detects the approaching person. The PIR output interrupt is sent to the "201-WIFI Module," which in turn sends an interrupt to the door lock system. The door lock system powers on the "100-Video Module." Based on the illumination information collected by the "111-Photosensitive Sensor," the "100-Video Module" configures the "107-Camera IR-Cut" and "109-Camera Module" to night vision or daytime mode. The "109-Camera Module" captures the video stream of the image in front of the door. The video stream, in UVC format, is transmitted to the "500-Display Module" on the rear panel via a USB cable connecting the front and rear panels. The "500-Display Module" then transmits the video stream to the "503-Memory Chip SPI" module. The LOGO image stored in "FLASH" is integrated with the UVC video stream transmitted from the front panel, and the integrated image is presented to the user inside the door through the "504-display". Simultaneously, the "100-video module" transmits the video stream to the "200-WIFI module". The "200-WIFI module" transmits the video stream collected by the system to the cloud via the WIFI network, and the cloud distributes it to the user's mobile APP. The user can view the locally occurring events and video stream on the APP. Accordingly, the implementation steps may include: responding to a second interrupt signal sent by the WIFI module, controlling the switching of the working mode of the camera in the camera module based on the ambient light information collected by the photosensitive sensor, and using the camera module to collect the door-front image information. The door-front image information is transmitted to the screen chip in the display module via a USB cable connecting the front and rear panels. The screen chip controls the display of the door-front image information on the display screen. The interrupt signal is sent to the video main control chip in the video module when the PIR human infrared proximity sensor in the WIFI module detects a human approaching. The door-front image information is then uploaded and stored in the cloud via the WIFI module so that the user can view the door-front image information in the cloud.

[0091] Accordingly, in the embodiments of this disclosure, as one possible implementation for controlling the door lock system, such as Figure 7As shown, a logic for the interaction between a video module and a door lock control system can be provided. The video system includes a video module 100, a Wi-Fi module 200, and a display module 500. The door lock control system includes a main chip module 300 and a rear panel module 400. Specifically, when a user approaches a door with the door lock system installed approximately 3 meters away, the "202-PIR human infrared proximity sensor," operating in a low-power state, detects the approaching human. The PIR sensor then wakes up the entire door lock system and video system. The video system captures and uploads or outputs the video stream to the "display module" on the rear panel. The user completes the authentication process of the door lock system through a "two-in-one module" or other authentication input modules ("306-finger vein module or fingerprint module", "311-button module", "313-smart card module"). The "400-Bluetooth rear panel module" on the rear panel controls the actions of "414-motor" and "415-lock body" to complete the unlocking or locking action. The user's series of actions of opening and closing the lock will be captured by the video system and uploaded to the cloud or the user's display screen inside the door, providing the user with a complete monitoring view.

[0092] In summary, according to the control method of the door lock system provided in this application, when a person is detected approaching the door lock, a biometric module is used for unlocking authentication, and the authentication result is sent to the control module. The control module then executes unlocking control on the lock body based on the authentication result.
