Description

Technical Field

[0001] This utility model relates to the field of door station technology, specifically a modular door station that can be expanded independently. Background Technology

[0002] In existing door station technologies, most devices have fixed functions and single interfaces, making it difficult to meet the diverse needs of different scenarios.

[0003] For example, in some high-end residential communities or commercial office buildings, the door access control unit may need to have a variety of advanced functions such as facial recognition, remote control, and voice interaction; while in some older communities or places with limited budgets, only basic access control functions may be needed.

[0004] However, existing door station configurations often lack the flexibility to adjust their functions, leading to resource waste or insufficient functionality. Furthermore, with the rapid development of IoT technology, the demands for intelligence and networking in door stations are increasing, while traditional door stations have significant limitations in interface expandability and network communication capabilities.

The side wall of the switch interface 15 away from the electric lock interface 18 is fixedly connected to an expansion board 22.

A microphone interface 25 is fixedly connected to the side wall of the expansion board 22 near the anti-tamper interface 24. A speaker interface 26 is fixedly connected to the side wall of the expansion board 22 near the microphone interface 25.

[0038] The main control board 13 has a Bluetooth interface 19 fixedly connected to the side wall near the electric lock interface 18, and a sensor interface 20 fixedly connected to the side wall near the Bluetooth interface 19. A power interface 21 is fixedly connected to the side wall at the bottom of the expansion board 22, and an SD card interface 27 is fixedly connected to the side wall at the top of the expansion board 22.

[0039] A touch screen display 2 is embedded and fixedly connected to one side wall of the protective shell 1. A display screen fixing plate 9 is fixedly connected to the side wall of the inner cavity 8 near the touch screen display 2. The end of the display screen fixing plate 9 near the touch screen display 2 is fixedly connected to the side wall of the touch screen display 2. A sensor plate 3 is provided on the side wall of the protective shell 1 at the bottom of the touch screen display 2.

The detection end of the camera 10 is positioned facing the end of the transparent hole 5.

[0040] The working principle of this utility model is as follows: When the door station is powered on, the main control board 13 begins initialization, loading the operating system and application programs. At the same time, various functional modules such as the camera 10, display screen, speaker 12, and microphone 11 also perform self-tests and initialization.

[0041] When someone approaches the door station, the human detection module senses the movement via the human sensor interface 23, triggering the camera 10 to perform facial recognition. The facial image captured by the camera 10 is compared by the image processing algorithm on the main control board 13. If the recognition is successful, the main control board 13 controls the door lock to open via the electric lock interface 18, allowing the person to enter.

[0042] During facial recognition or access control, speaker 12 is used to play prompts and voice messages, such as "Please scan your face" or "Door is open." Simultaneously, microphone 11 is used to collect user voice commands to enable voice interaction.

[0043] The door station can be connected to various external devices or sensors, such as card readers, fingerprint recognition modules, and temperature sensors, via the first expansion connector 6 and the second expansion connector 7, to achieve more functions. These external devices are connected to the main control board 13 or the expansion board 22 through corresponding interfaces to realize data transmission and control functions.

[0044] During the operation of the door station, the main control board 13 will periodically check the status of each functional module. If a module is found to be faulty, such as the camera 10 failing to recognize a face or the display screen going black, the main control board 13 will generate a corresponding fault code and report it to the user or after-sales personnel through the network interface 14 or the display screen so that timely repair and replacement can be carried out.
