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] The purpose of this invention is to provide a classroom environment sensing and control device that can improve the equipment connectivity and ease of operation in a classroom system.
[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 1-2 As shown, this utility model provides a classroom environment sensing and control device, including: a client 1, a cloud server 2, a control terminal 3, a control device 4, a sensor assembly 5, an execution module 6, a camera 7, and a communication module 8.
[0024] The client 1 is connected to the cloud server 2, and both the client 1 and the cloud server 2 are connected to the communication module 8; the camera 7 and the communication module 8 are both connected to the control terminal 3; the control terminal 3 is connected to the power supply via a UART serial port and is soldered to the PCB socket according to the corresponding pins; the control device 4 is connected to the PCB socket and is connected to the sensor assembly 5 via any serial port or GPIO port; the execution module 6 is connected to the control device 4 via the PCB socket.
[0025] In one specific implementation, the control terminal 3 is also connected to the Baidu AI server through the communication module 8, and the Baidu AI server is also connected to the client 1.
[0026] In one specific implementation, the sensor assembly 5 includes: a temperature sensor, a humidity sensor, an alcohol sensor, a smoke sensor, a carbon dioxide sensor, and a photosensor.
[0027] In one specific implementation, the execution module 6 includes: a buzzer, a device controller, and a relay; wherein the device controller includes an LED light and a servo motor.
[0028] In one specific implementation, the control terminal 3 uses an i.MX6ULL processor, and the control device 4 uses an STM32 microcontroller.
[0029] Based on the above technical solution, the following embodiments are provided.
[0030] In this embodiment, the device mainly includes the following components:
[0031] (1) IMX6ULL development board: connected to power supply via serial port (UART).
[0032] (2) PCB socket: The pins of the PCB socket correspond to the pads on the circuit board and are connected to the circuit board by soldering.
[0033] (3) STM32 microcontroller: The STM32F103C8T6 chip is selected and connected to the circuit board through the PCB socket.
[0034] (4) Sensors: There are temperature sensors, humidity sensors, alcohol sensors, smoke sensors, carbon dioxide sensors and photosensors, which are used to monitor classroom environmental parameters. They are installed on the circuit board through PCB sockets, and each sensor is connected to the STM32 microcontroller through serial port or GPIO port.
[0035] (5) Camera 7: Connect to it via the built-in camera 7 module interface on the IMX6ULL development board.
[0036] (6) Execution Module 6: This module includes LED lights, relays, servos, and a buzzer. The LED lights simulate the classroom lighting system, the relays simulate the curtains and air conditioner switches, the servos simulate the access control switches, and the buzzer simulates the alarm system. Each actuator is connected to the microcontroller via a PCB socket. The relays also need to be connected to an additional separate power supply module (not the power supply mentioned above).
[0037] (7) Communication module 8: A WIFI module is used for data transmission and is connected to it through the SDIO WiFi interface built into the IMX6ULL development board.
[0038] After the device is started, sensor component 5 begins to collect environmental data in the classroom in real time and transmits the data to the STM32 microcontroller. The STM32 microcontroller transmits the data to the i.MX6ULL processor for processing and analysis. The processor determines whether the environmental parameters in the classroom need to be adjusted based on preset thresholds. If adjustment is required, the processor sends control commands to relevant devices, causing the devices to perform corresponding actions according to the received commands. Wireless control of connected devices is achieved through button control or built-in voice control. Furthermore, based on the structure of this embodiment, by embedding the Linux operating system and existing QT programs into the i.MX6ULL processor, human-computer interaction and remote management can also be realized. For example, the required data can be obtained by controlling the acquisition timing of each sensor, displayed on an OLED screen, and then integrated into data packets, which are sent to cloud server 2 via the MQTT protocol. Cloud server 2 makes judgments based on the corresponding built-in data thresholds and issues corresponding commands to control terminal 3 for display. Voice recognition and face recognition are implemented through HTTP requests initiated by Baidu AI, and timetable queries can be achieved by querying the database service in cloud server 2.
[0039] Therefore, the device structure in this embodiment, combined with the embedded system, enables attendance management and information interaction based on client software and a server. For example, after students clock in using facial recognition, teachers can view students' attendance through the client software, students can view their class schedules, grades, classroom usage status, and other information, and administrators can remotely monitor the system through the server.
[0040] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope.
