[0024] 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.

[0025] In today's business world, advertising, as an important marketing tool, plays a crucial role in helping companies promote their products and services and enhance brand awareness. With the continuous advancement of technology, advertising display technology has also evolved from traditional paper posters and lightbox advertisements to electronic display screen advertisements, such as LED displays and LCD displays. These can display dynamic images, videos, and other content, possessing stronger visual impact and appeal, and are widely used in public places such as shopping malls, train stations, and airports.

[0026] Due to the limitations and technical defects of existing technologies, please refer to... Figures 1-5 This embodiment provides an intelligent advertising screen based on STM32 microcontroller control, which has the advantage of being switchable between unidirectional and bidirectional use, and can cope with more application scenarios. The advertising screen includes a support column 1 and a main screen shell 2 installed on the top of the support column 1. The front of the main screen shell 2 is provided with a main screen 3, and the back of the main screen shell 2 is provided with a receiving groove 201. A secondary screen shell 4 is hinged in the receiving groove 201. A secondary screen 5 is provided on the side of the secondary screen shell 4. The top of the receiving groove 201 is provided with two clearance grooves 202. A locking component 6 connected to the secondary screen shell 4 is fixed in the clearance groove 202. When bidirectional display is required, the secondary screen 5 can be placed behind the main screen 3. When unidirectional display is required, the secondary screen 5 can be rotated to be above the main screen 3. Under the action of the locking component 6, the secondary screen shell 4 can be fixed to maintain the stability of the secondary screen 5 during use.

[0027] Although the secondary screen housing 4 can rotate on the main screen housing 2, its movable nature makes it unstable during use. For this issue, please refer to [link / reference needed]. Figure 5 The locking component 6 includes a guide frame 601 fixed in the clearance groove 202. The guide frame 601 has a guide hole, and a stud 602 connected to the sub-screen housing 4 is slidably disposed in the guide hole. One end of the stud 602 is threadedly connected to a nut 603. When the sub-screen housing 4 rotates, it can drive the stud 602 to move in the guide frame 601. When it moves to the correct position, the nut 603 can be used to lock the stud 602, thereby fixing the sub-screen housing 4.

[0028] In practical applications, the advertising screen should have diverse functions. To this end, a wireless communication module 7, a temperature and humidity sensor 8, and an infrared sensor 9 are embedded side by side at the bottom of the front of the main screen housing 2. A date display screen 10, a temperature and humidity display screen 11, and an air quality display screen 12 are arranged side by side at the top of the front of the main screen housing 2. By setting the temperature and humidity sensor 8 and the infrared sensor 9, the ambient temperature and humidity can be monitored and displayed in real time. The infrared sensor 9 can detect whether there are pedestrians around, so that the lights turn on when people are there and turn off when people leave, which has the advantage of reducing energy consumption. It also has the functions of monitoring date, temperature and humidity, and air quality. Furthermore, two symmetrically arranged lighting lamps 13 are set at the top of the front of the main screen housing 2. The lighting lamps 13 can be used to illuminate the surrounding environment, making it easier to see the content displayed on the advertising screen.

[0029] Furthermore, a control panel 14 is fixedly provided on one side of the front of the main screen housing 2; the control panel 14 is equipped with multiple buttons, including a power switch, a function switching button, a brightness adjustment button, etc.; at the same time, an STM32 chip controller 15 is embedded in the side wall of the main screen housing 2; the STM32 chip controller 15 is used to control the operation of the electrical equipment inside the entire advertising screen.

[0030] When the ambient temperature is too high, the entire system will be in a high-temperature state during operation, which will lead to malfunction. To address this issue, cooling fans 16 are installed on both sides inside the main screen casing 2, and a dustproof mesh 17 is embedded in the side wall of the main screen casing 2 directly opposite the cooling fans 16. A cover 18 fixed to the main screen casing 2 is provided above the dustproof mesh 17. By setting up the cooling fans 16 and the dustproof mesh 17, the internal components can be actively cooled in high-temperature environments, avoiding the problem of excessive temperature affecting use.

[0031] Furthermore, the main screen 3, the secondary screen 5, the date display screen 10, the temperature and humidity display screen 11, and the air quality display screen 12 all adopt LED dot matrix screens; the use of LED dot matrix screens has the advantages of fast response and dynamic display.

[0032] It should be noted that 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.

[0033] 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.
