[0002] Traditional building intercom systems typically employ fixed installations, and their facial recognition modules often have cameras facing a single direction (mostly horizontal or slightly tilted). This leads to significant limitations in practical applications: existing devices struggle to meet the recognition needs of individuals with dwarfism, wheelchair users, and children. Because their faces are below the camera's field of view, these individuals often require assistance from others or rely on alternative verification methods such as access cards, reducing access efficiency and violating accessibility design principles. To address these shortcomings, we propose a mobile building wireless intercom system. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] A mobile building wireless intercom device includes a device base, which consists of a base plate 10 and a support cylinder 11 vertically fixed to the upper surface of the base plate 10. The bottom of the base plate 10 is provided with mounting holes, and the inner wall of the support cylinder 11 is reserved with heat dissipation holes. The base plate 10 is fixed to the ground through the mounting holes, and the support cylinder 11 is vertically welded to the upper surface of the base plate 10. The reserved heat dissipation holes on the inner wall enable natural heat dissipation.

[0028] The upper surface of the support cylinder 11 is a 45° inclined surface. Its top end is rotatably connected to the rotating disk 12 through a bearing. The rotating disk 12 has a through hole in the center. The rotating disk 12 is connected to the support cylinder 11 through the bearing. The wire harness tube 13 is embedded in the central through hole. The inner wall of the wire harness tube 13 is provided with a wire harness groove 14. The wire harness groove 14 is used to organize the power cord and data cable.

[0029] A face recognition mechanism, including a housing 20, is fixedly installed on the upper surface of the rotating disk 12. The housing 20 has a flange 23 on its surface and forms a 45° angle with the support cylinder 11. The housing 20 is fixed to the rotating disk 12 by bolts through the flange 23. The housing 20 integrates a face recognition camera 21 and a display screen 22, supporting liveness detection and feature code comparison.

[0030] The support cylinder 11 integrates an access control card reader 50, an intercom 51, and control buttons 52 on its surface. The upper surface of the support cylinder 11 is designed with a 45° inclination to ensure that the device housing 20 is at the optimal human-machine interaction angle after the rotating disk 12 is installed. The access control card reader 50 is located on the surface of the support cylinder 11 and supports card swiping at a distance of 1-3cm or mobile phone NFC recognition to trigger the access control switch signal. The intercom 51 communicates with the indoor unit through a wireless module such as an IoT DTU to realize two-way audio and video calls (the face recognition camera 21, display screen 22, access control card reader 50, and intercom 51 are all existing technologies and will not be described in detail).

[0031] The inner wall of the support cylinder 11 is provided with a drive assembly, including a motor 30 fixedly installed on the inner wall of the support cylinder 11. A first spur gear 31 is fixedly installed at the output end of the motor 30. A second spur gear 32 is fixed on the outer wall of the wire harness tube 13 and meshes with the first spur gear 31 driven by the motor 30. The motor 30 can control the rotating disk 12 to rotate 180°. The control button 52 is used to manually control the motor 30 to start and stop. When the motor 30 starts, the first spur gear 31 drives the second spur gear 32 to rotate, and transmits torque to the rotating disk 12 through the wire harness tube 13, so that the face recognition mechanism switches between the upward and downward states.

[0032] The device housing 20 is provided with a protective cover 40. A threaded post 41 is fixedly installed on the inner top wall of the protective cover 40. The top of the device housing 20 is provided with a threaded hole 42. The protective cover 40 is made of transparent acrylic material and covers the face recognition camera 21 and the display screen 22. The transparent acrylic protective cover 40 is fixed by the threaded post 41 and the threaded hole 42. The light transmittance is over 93%. The protective cover 40 can shield the device housing 20 and also has dustproof and impact-proof performance.

[0033] Specifically, the working principle and operation method of this utility model are as follows:

[0034] Facial recognition function operation

[0035] By default, the face recognition camera 21 faces upwards, suitable for users taller than 1.4 meters. The user stands 50cm in front of the device and looks directly at the display screen 22. The system automatically locates the face and completes liveness detection using the HOG algorithm. After successful recognition, the access control automatically unlocks, and the display screen 22 shows "Verification passed".

[0036] Switching operation: Press and hold the control button 52. The motor 30 drives the first spur gear 31 to drive the second spur gear 32, causing the rotating disk 12 to rotate 180°. The face recognition camera 21 switches to the downward position. Short users, such as those under 1.2 meters tall, can approach the device, look up and face the face recognition camera 21 to complete the recognition.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
