[0002] Electronic class signs, as an important component of smart campus construction, have been widely adopted in primary and secondary schools. Traditional electronic class signs primarily display class information, notices, timetables, and campus activities. These functions mainly focus on one-way information display and basic administrative support, with limited interactivity. With the development of artificial intelligence technology, students' demand for personalized and real-time learning guidance is increasing. Currently, when students encounter learning difficulties, they usually need to seek help from teachers, classmates, or use photo-based question-solving apps on their mobile phones or other personal electronic devices. The former is limited by time and space, and may not provide timely answers, while the latter can easily distract students during class or self-study time, and schools typically have strict regulations on student mobile phone use.

[0003] Therefore, how to utilize existing information technology equipment on campus to provide students with a convenient and focused learning aid is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] 1. This utility model integrates an optical lens into an electronic class sign. Students do not need to use their personal mobile phones; they can simply place their test papers or exercises below the class sign to take pictures and ask questions. At the same time, this utility model optimizes the shooting angle, ensuring complete and clear coverage of the shooting area at a conventional installation height. The operation process is greatly simplified, making it suitable for students taking pictures of questions in wall-mounted environments. It effectively avoids the inconvenience and awkward posture of the traditional "raising your hand to take a picture with the front camera" operation, improving the shooting experience and the aesthetics of the scene.

[0017] 2. This utility model can automatically turn on the fill light when it detects that the ambient light is too dim and may affect the clarity of the image, so as to provide a uniform and soft light source for the shooting area and ensure that high-quality images can be obtained under any lighting conditions.

[0018] 3. This utility model expands the application scenarios of electronic class signs, upgrading them from a simple information display tool to an intelligent learning terminal with human-computer interaction capabilities.

[0019] 4. This utility model provides students with a convenient and focused learning aid, effectively avoiding problems such as students being distracted in class and browsing irrelevant content due to the use of personal devices such as mobile phones, which is conducive to maintaining classroom discipline and a good learning atmosphere.

[0025] Example 1

[0026] See Figures 1 to 3 As shown, the AI ​​electronic class sign provided in this embodiment includes a class sign body 1, an image acquisition module 2, an embedded motherboard 3, a speaker 4, and a microphone 5;

[0027] The main body 1 of the class sign is in a horizontal position and includes a flat shell 101. The front end of the flat shell 101 is provided with a display screen mounting position. The display screen 102 is installed at the display screen mounting position and displays in a horizontal position. The display screen 102 is an LCD or OLED touch screen. The rear end of the flat shell 101 is provided with several heat dissipation holes 1011 and fixing holes 1012 for fixing to the wall.

[0028] The image acquisition module 2 includes a tilting bracket 201, an optical lens 202, a fill light 203, and an ambient light sensor 204. The tilting bracket 201 is installed at the bottom edge of the class sign body 1, and the optical lens 202 is installed on the tilted surface of the tilting bracket 201, so that the optical lens 202 is tilted outward and forms an angle of 13°-15° with the bottom edge of the class sign body 1, for acquiring images towards the user's operating area, ensuring complete and clear coverage of the A4 paper-sized area below at a normal installation height. A fill light 203 and an integrated ambient light sensor 204 are mounted around the optical lens 202. The optical lens 202 is a high-definition wide-angle camera. Two sets of fill lights 203 are respectively arrayed and installed on both sides of the high-definition wide-angle camera. The optical lens 202, fill light 203, and ambient light sensor 204 are connected to the embedded motherboard 3. When the ambient light is detected to be too dark, which may affect the clarity of the image, the fill light 203 is automatically turned on to provide a uniform and soft light source for the shooting area, ensuring that high-quality images can be obtained under any lighting conditions.

[0029] The embedded motherboard 3 is integrated into the main body 1 of the class sign and connected to the image acquisition module 2 and the display screen 102. The embedded motherboard 3 has a built-in Android smart operating system. The embedded motherboard 3 includes a processor 301, a communication module 302, a memory 303, and a power module 304. The processor 301 and the power module 304 are respectively connected to the communication module 302, the image acquisition module 2, the microphone 5, the speaker 4, and the memory 303. The memory 303 is used to receive data from the processor 301 and communicates with the server 6 through the communication module 302. Preferably, the memory 303 is pre-installed with image analysis software for local OCR processing of captured images. The embedded motherboard 3 is communicatively connected to the server device 6, which is a local server or a cloud server. The server device 6 integrates an LLM large language model 7.

[0030] The microphone 5 and speaker 4 are both integrated in the main body 1 of the class sign. The microphone 5 and speaker 4 are both connected to the server device 6 and the large language model 7 through the embedded motherboard 3.

[0031] The workflow of the AI ​​electronic class sign provided in this embodiment is as follows:

[0032] Students place their test papers or workbooks with difficult questions in the shooting area below the main body of the class sign 1, and click the virtual button on the display screen 102. After receiving the trigger signal, the embedded motherboard 3 immediately controls the image acquisition module 2 to take a picture and acquire image data containing the questions.

[0033] Subsequently, the embedded motherboard 3, connected via a network interface (not shown in the figure) to the LLM large language model 7 stored in the server device 6, directly processes the image, identifies the problem, analyzes and calculates it, and generates detailed solution steps and answers. Preferably, the embedded motherboard 3 calls the image analysis software mounted on the memory 303, which can preprocess the image, such as denoising and tilt correction, and then identify the question area in the image using deep learning technology. Next, it is analyzed by the LLM large language model 7.

[0034] Finally, the embedded motherboard 3 will format the solution result, including a screenshot of the original question, solution steps, and final answer, and send it to the display screen 102 for easy comparison by students. Students can ask follow-up questions via microphone 5 based on the displayed answer. The embedded motherboard 3 will capture the speech, convert it into text, and send it again to the LLM Large Language Model 7 to achieve continuous dialogue until the student fully understands. Furthermore, the LLM Large Language Model 7 can be requested to generate related variant questions for students to practice and reinforce their understanding.
