Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, a smart campus terminal according to this utility model includes a housing 1. A touch screen 2 is disposed on the front of the housing 1. Inside the housing 1, there is a cavity for accommodating and electrically connected to the touch screen 2, and a main control circuit board 4. The power supply battery 3 and a main control circuit 5 are disposed on the front of the main control circuit board 4. An induction coil 6 is disposed on the inner wall of the back side of the main control circuit board 4 near the front end of the housing 1. A sensor assembly 7 is disposed on the inner wall of the middle part of the housing 1 on the back side of the main control circuit board 4. The main control circuit 5 includes a microprocessor, a wireless communication module, an NFC read / write module, a positioning module, a data storage module, and a recording module. The microprocessor is electrically connected to the touch screen 2, the wireless communication module, the positioning module, the data storage module, the sensor assembly, and the recording module. The power supply battery 3 is electrically connected to the main control circuit 5 on the main control circuit 4, providing power to each module of the main control circuit 5. The induction coil 6 is connected to the microprocessor via an NFC read / write module. In this invention, the touch screen 2 is a 3.2-inch TFT LCD screen. The positioning module is used to locate the user and the terminal. The induction coil 6 is an NFC antenna used to receive NFC radio frequency signals and receive NFC contactless payment requests through the NFC read / write module. The NFC read / write module enables basic contactless reading and writing functions, allowing the terminal to make payments on campus. The data storage module is a Flash memory, a SIM memory card, an SWP-SIM memory card, or an SD memory card. The NFC read / write module uses a contactless radio frequency (RFID) S50 chip. As a high-frequency (13.56MHz) chip, the S50 chip uses wireless radio frequency technology for communication, requiring no physical contact. It has a rewritable function and can store, process, and transmit data, improving the convenience of reading and inputting data. The smart campus terminal, based on an NFC read / write module, writes student identity information and related spending amounts into a data storage module and uploads the personal information to the school's public service platform. This allows for personalized information updates, which can be initiated after feedback to the public service platform. Personal information can be re-personalized or deleted and then updated again. Therefore, this smart campus terminal can be integrated into the same system within the campus network, providing convenience for students' daily lives and offering a channel for teachers and school management. It can be deployed into the campus network system without altering the existing school architecture, enabling students to easily communicate and exchange information on campus.

[0022] In this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, a USB data interface 8 and an audio input module 9 are provided on the rear side wall of the outer casing 1. The audio input module 9 is a microphone. An audio output module 10 is provided on the front surface of the outer casing 1. The audio output module 10 is a speaker or miniature speaker. The audio input module is connected to the microprocessor through a recording module. The recording module can encode the student's recording information and perform voice communication. The audio output terminal of the microprocessor is connected to the audio output module. Audio signals can be input to a teacher's management terminal (mobile terminal, tablet computer, or PC) or a parent's mobile terminal through the audio output module 10 and the audio input module 9. In the classroom, this smart terminal can be used for classroom teaching. By turning on the recording function and recording the teaching content through the recording module, students can easily record complex knowledge points after class and organize them, facilitating student learning, use, and daily interaction and communication. It is understood that both verbal communication and school-wide broadcasting on campus have drawbacks such as poor timeliness, low notification efficiency, and high uncertainty. However, the wireless communication module and voice input and output module of this campus terminal can enable timely communication with teachers. Therefore, teachers can send messages one-to-one to students' terminals through the wireless communication module, without worrying about difficulties in communication between teachers and students or missing campus notices. This not only greatly improves the efficiency of teachers in selecting notification recipients online, but also transforms information from widespread and redundant broadcasts into precise and efficient targeted notifications, reducing the probability of students being disturbed by irrelevant messages.

[0023] In this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the sensor assembly 7 includes a temperature and humidity sensor, an atmospheric pressure sensor, a ranging sensor, and an attitude sensor. These sensors are electrically connected to the microprocessor, which uses an RP2040 processor. The temperature and humidity sensor is an SHT20 sensor, capable of reliably measuring ambient temperature and humidity with extremely low power consumption. The SHT20 uses I... 2The C-bus communicates with the microprocessor, monitors ambient temperature and humidity data via temperature and humidity sensors, and provides temperature information to the user, allowing them to stay informed about weather changes. A BMP280 barometric pressure sensor detects the air pressure value based on the user's climbing height (or floor height) during motion monitoring, enabling counting and identification of the current floor. An MPU6050 posture sensor identifies and determines whether the user is in motion, walking, or lying down asleep, providing timely information about their current state. By monitoring the user's movement, the posture sensor records daily sleep duration and sleep patterns, allowing students to adjust their schedules and improve sleep quality. Sleep quality; the ranging sensor uses a US100 ultrasonic ranging module. The ranging sensor detects the vertical distance from the terminal's location to the student (user). It can be preset to alarm at distances of 50-100cm. When the terminal moves more than 50-100cm away from the ranging sensor, the sensor sends its positional distance to the microprocessor, which then sends an alarm message to the audio output module 10 to remind the user to move away from its designated area. If the reminder doesn't end within a preset time, it is promptly sent via wireless communication to the corresponding teacher management terminal (mobile phone, tablet, or PC) or parent's mobile phone, allowing for timely access to the student's information. For this purpose, sensors such as posture sensors and ranging sensors are used to acquire the student's movement status and surrounding information within the campus life device, monitoring and recording daily exercise. Through this exercise information, students can receive real-time feedback, allowing them to better adjust and monitor their exercise plans. This smart terminal can also be used in classroom teaching to monitor student posture, issuing alarms for incorrect postures to remind users to adjust their posture. This utility model of a smart campus terminal is designed for school life, effectively solves difficult problems, and provides convenience for school management.

[0024] In this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, a rear scanner 11 connected to the microprocessor is disposed on the back side of the main control circuit board 4 and on the front rear side wall of the housing 1. The rear scanner 11 scans relevant QR codes to make payments or view relevant information on the school's public service platform through the terminal. The wireless communication module is two or more of the following: GPRS, ZigBee, RoLa, and Bluetooth. The positioning module is a Beidou or GPS positioning module. This utility model uses a combination of RoLa wireless module and Bluetooth communication module. The student terminal can transmit information to the corresponding teacher management terminal through the RoLa wireless module on campus, thereby enabling timely... This invention acquires relevant student information and integrates the smart campus terminal into the same system within the campus network. This not only provides convenience for students' daily lives but also allows for interconnection with the school's public service platform (such as the school cafeteria ordering platform) via the terminal's wireless communication module. Students can send their dining or ordering requests to the school cafeteria ordering platform and make payments. The school cafeteria can then arrange the supply of meals based on the reservation feedback. Furthermore, the school cafeteria can allocate cafeteria windows according to dining demand, significantly alleviating queuing issues and effectively solving the problems of food waste and long queues in school cafeterias. This not only avoids waste but also makes school meals more in line with students' preferences.

[0025] In this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the main control circuit also includes a touch control module, which includes a touch chip U10, resistors R10, R11, R13, and R12, a signal control transistor Q10, and a touch switch BC. A touch switch is located on the left or right sidewall of the housing 1. The output terminal of the touch chip U10 is connected to the gate of the signal control transistor Q10 and one end of resistor R10. The contact terminals of the touch chip U10 are connected to one end of resistor R11 and one end of capacitor C10. The other end of resistor R10 is connected to the touch switch BC through resistor R12. The source of the signal control transistor Q10, the other end of resistor R10, and the other end of capacitor C10 are connected to ground. The signal control transistor Q10 is a CMOS transistor; its source is connected to the operating power supply, and its drain is grounded to prevent interference. The touch signal provides good protection and limitation. The touch switch BC is a one-way or two-way touch switch. The touch chip U10 uses a PT2041A channel touch detection chip. This chip has a built-in voltage regulator circuit to provide a stable voltage for the touch sensing circuit. When the student (user) touches the touch switch BC, the third pin TCH of the touch chip U10 receives the touch sensing signal. At this time, the first pin QC of the touch chip U10 outputs a synchronous trigger signal to start the terminal and turn on the power supply. This allows the power supply battery 3 to provide working power voltage to the various modules in the main control circuit 5. The touch screen 2 lights up, allowing operation to be performed on the various operation buttons displayed on the touch screen 2. After pressing the touch switch BC to turn on the power and start the terminal, interactive operation can be performed through different icons on the touch screen 2.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
