Description

Technical Field

[0001] This utility model relates to the field of multimedia terminal technology, specifically to a smart multimedia terminal based on facial recognition technology. Background Technology

[0002] Multimedia terminals, as an important tool for modern information dissemination, typically consist of three core components: terminal software control, network information transmission, and multimedia terminal display, collectively forming a complete advertising broadcasting and control system. This system is widely used in various public places, such as shopping malls, stations, and residential communities. It achieves advertising goals by displaying a variety of multimedia materials, including images, text, and videos, as well as providing real-time information plugins (such as weather and exchange rates). However, this advertising dissemination method is often one-way; the advertising content is delivered to the audience through the multimedia terminal, while the audience passively receives the information.

[0003] In densely populated residential environments such as community centers, multimedia terminals are frequently used not only for advertising but also for security monitoring and access control systems. Facial recognition technology is crucial for achieving these functions. However, currently common facial capture cameras are usually fixed in a specific location, which limits their effectiveness in capturing faces. Users need to adjust their posture and position according to the camera's location. During facial recognition, the fixed camera position cannot be adjusted based on the user's height and location, thus failing to effectively capture facial information and resulting in inaccurate facial recognition. This not only affects residents' normal entry into the community but may also pose a security risk to the community. Therefore, we provide a smart multimedia terminal based on facial recognition technology to solve these problems. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a smart multimedia terminal based on facial recognition technology, including a mounting box 3. Inside the mounting box 3, two electric slide rails 11 are installed. The outer surfaces of the two electric slide rails 11 are slidably mounted on a movable frame 12. Inside the movable frame 12, there is a partition 13. The outer surface of the partition 13 is equipped with a motor 14. The output end of the motor 14 passes through the partition 13 and is equipped with a threaded rod 15. The left end of the threaded rod 15 is rotatably mounted inside the movable frame 12. The outer surface of the threaded rod 15 is threadedly connected to a movable block 16. The outer surface of the movable block 16 is equipped with a recognition camera 17. The outer surface of the mounting box 3 is equipped with a controller 4.

[0022] The mounting box 3 has a heat dissipation frame 8 installed on its outer surface. The heat dissipation frame 8 has a fixing frame 9 installed inside its interior. The fixing frame 9 has a cooling fan 10 installed on its outer surface. The cooling fan 10 can draw air from the mounting box 3 and dissipate the hot air inside, effectively reducing the internal temperature of the equipment and helping to prevent the equipment from overheating and keep the equipment within a suitable operating temperature range.

[0023] The inner wall of the mounting box 3 is equipped with a mounting bracket 18, and the outer surface of the mounting bracket 18 is provided with multiple positioning holes 19. By providing the mounting bracket 18 and the positioning holes 19, electrical components can be easily installed and removed.

[0024] The inner bottom wall of the mounting housing 3 is equipped with a filter plate 22. The function of the filter plate 22 is to filter the air entering the mounting housing 3, preventing dust and impurities from damaging the internal electrical components. This helps keep the equipment clean, reduces maintenance costs, and extends the service life of the equipment. A backup power supply 20 is installed on the outer surface of the filter plate 22. The backup power supply 20 can provide independent power supply in the event of a power outage, providing power support for a period of time. It can continue to perform its functions, such as facial recognition and advertising display, until the main power is restored, thereby reducing downtime caused by power outages.

[0025] The outer surface of the mounting box 3 is equipped with a display screen 5, and the upper surface of the mounting box 3 is equipped with two support rods 6.

[0026] The top of the two support rods 6 are jointly fitted with a top cover 7, and a support base 1 is installed on the bottom surface of the mounting box 3.

[0027] The support base 1 has multiple ventilation holes 21 on its outer surface and two support pads 2 on its bottom surface. External cold air enters the interior of the mounting box 3 through the ventilation holes 21. During the process of cold air entering, it will cool down the power supply 20 and the electrical components installed on the mounting bracket 18 inside the mounting box 3, thereby assisting the cooling fan 10 in cooling the inside of the equipment.

[0028] Working principle: In use, firstly, the device is placed in the designated area using the support pad 2. When a person approaches, the recognition camera 17 starts working, capturing the person's position information. This information is sent to the controller 4 for processing. The controller 4 then starts the motor 14, which drives the threaded rod 15 to rotate. The rotation of the threaded rod 15 causes the moving block 16 and the recognition camera 17 to move up and down inside the moving frame 12, thus flexibly adjusting the usage height according to people of different heights. At the same time, the electric slide rail 11 is activated, causing the moving frame 12 and the recognition camera 17 to move left and right inside the moving frame 12. The identification position can be flexibly adjusted according to the location of the personnel. During use, the cooling fan 10 is activated to draw air out of the mounting box 3 and dissipate the hot air inside. At the same time, cold air from outside enters the mounting box 3 through the ventilation hole 21. During the process of the cold air entering, it will cool down the power supply 20 and the electrical components installed on the mounting bracket 18 inside the mounting box 3, which helps to keep these components within a suitable operating temperature range. The incoming air will be filtered through the filter plate 22 to prevent external dust and impurities from affecting the internal electrical components, thereby protecting the long-term stable operation of the equipment.

[0029] 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.
