[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] Example 1
[0022] like Figures 1-3 As shown, the smart classroom management system based on the concept of energy conservation and emission reduction includes an ambient light sensor, a temperature sensor, a face recognition module, a 51 microcontroller, an ATmega16U2 chip, a voice broadcast module, an LCD display screen 3, and several lights, electric curtains, and fans installed in the classroom.
[0023] The temperature sensor is connected to the input terminal of the development board containing the 51 microcontroller; the LCD display and fan are connected to the output terminal of the development board containing the 51 microcontroller; the ambient light sensor and face recognition module are connected to the input terminal of the Arduino uno R3 motherboard with the ATmega16U2 chip; the voice broadcast module, lights, and electric curtains are connected to the output terminal of the Arduino uno R3 motherboard with the ATmega16U2 chip.
[0024] The ambient light sensor, temperature sensor, face recognition module, 51 microcontroller, ATmega16U2 chip, voice broadcast module, and LCD display screen 3 are integrated into one unit mounted on the housing 2. The face recognition module is a camera.
[0025] The camera is installed at the upper front of the housing 2, and the LCD display screen 3 is also installed at the front of the housing 2.
[0026] Working principle:
[0027] This embodiment has the following functions:
[0028] 1. Intelligent balance of indoor and outdoor light: When there is sufficient natural light from outside, the brightness of the lights will be appropriately reduced, and the curtains will be automatically opened to make full use of natural light sources and further save energy; when the light from outside dims, the curtains will be automatically closed, and the lighting will be adjusted to ensure that the light in the classroom is always at the best level.
[0029] 2. Intelligent Temperature Control Fan: A temperature sensor monitors real-time temperature changes in the classroom, and combined with 51 microcontroller technology, it achieves precise adjustment of fan speed. The fan speed is set to three levels: below 25℃ (Level 1), 25-29℃ (Level 2), and above 29℃ (Level 3). This avoids the over-cooling or overheating problems that may occur with traditional fixed-mode operation, achieving both energy savings and ensuring indoor comfort.
[0030] 3. Facial Recognition Monitoring Alarm: Utilizing a facial recognition smart camera trained with an AI chip, it can accurately identify whether there is anyone in the classroom. When the classroom is detected to be empty, it will automatically issue a reminder to turn off unnecessary power.
[0031] This invention reduces unnecessary energy consumption and achieves energy efficiency by automatically adjusting lights and electrical appliances; it maintains suitable light and temperature to improve the comfort of studying and working; it prevents power waste through intelligent reminders; and it contributes to environmental protection by reducing energy consumption and emissions.
[0032] This invention comprehensively utilizes light sensing, temperature sensing, 51 microcontroller control technology, ATmega16U2 chip control technology, and facial recognition and speech synthesis modules to achieve precise control of the classroom through multiple systems, while maintaining relatively low energy consumption. This smart classroom management system enables centralized control and management of classroom lights, automatically adjusting brightness based on indoor lighting and human activity, significantly saving electricity while meeting lighting needs. Temperature-controlled fans monitor indoor temperature in real time via sensors, achieving precise temperature control and improving energy efficiency. The facial recognition system controls the entire classroom through specific data, reducing manpower consumption.
[0033] This utility model design not only emphasizes energy conservation but also focuses on user-friendliness. This is reflected in the following aspects:
[0034] (1) The 51 microcontroller is small in size, low in power consumption, low in cost, powerful in function, high in reliability and easy to use. Compared with ordinary temperature control fans, the 51 microcontroller temperature control fan has obvious advantages in intelligent control, energy efficiency, user interaction experience and multifunctionality.
[0035] (2) Facial recognition is more accurate than traditional infrared recognition. Traditional infrared detection is prone to misjudging heat sources, while facial recognition is more precise and accurate. When no one is detected in the classroom, an automatic reminder is issued to turn off unnecessary power, avoiding the situation where lights are left on when people leave.
[0036] (3) Use an ambient light sensor to automatically adjust indoor lighting. When the room is dark, the lights become brighter; when the room is bright, the lights become dimmer.
[0037] (4) The face recognition intelligent control system has low energy consumption: it uses integrated sensors, which helps classrooms save energy while its own power consumption is also very small.
[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
