01

Through analyzing the service orientation and professional positioning, we determined the training objectives for the major, followed by a three-level breakdown of the training objectives, corresponding to TC capabilities, and subsequently established the necessity of offering this course. The course design starts from “knowledge, ability, and quality”, and derives various aspects of the course from the training objectives, including teaching goals, expected learning outcomes, teaching content, and implementation methods. This ensures alignment with students’ cognitive patterns and professional ability development patterns, and selects typical learning projects to gradually cultivate students’ professional work abilities and autonomous learning capabilities through theoretical learning and practical training. After students complete this course, we assess, sort, and analyze the learning outcomes as an important basis for continuous course improvement.

Project Two

​

Project Name: Smart Home System

Project Source: Course Project “Embedded System Design”

Instructor: Sun Lifei

Student Team: Wang Xin, Sun Zhangpeng, Liu Jisheng, Liu Mingyu

Project Introduction

Implemented functions include: OLED display, LED lights, temperature and humidity detection, buzzer reminders, servo fan rotation, buttons, servo rotation automatic door opening, and card swipe door opening.

Enhanced functions include: The system can open the door with a room card, keychain, mobile access card, etc. When a person enters the room, the door will automatically close after a set time. It can also add and delete cards through buttons and display them on the OLED screen when entering the room.

To ensure safety, a threshold temperature for the temperature sensor will be set. When the indoor temperature exceeds the threshold due to fire or other reasons, the LED light will flash, the buzzer will sound an alarm, and the fan will rotate to cool down. When the temperature falls below the threshold, the buzzer stops sounding. The threshold temperature can be controlled via buttons to adapt to weather temperature changes.

Project Three

​

Project Name: Laser Distance Meter

Project Source: Course Project “Embedded System Design”

Instructor: Sun Lifei

Student Team: Chen Weitong, Hou Guohua, Liu Bailing, Wang Linhao.

Project Introduction:

This project designed a laser distance meter based on the STM32 microcontroller, integrating various modules and components such as the MPU6050 gyroscope module, HC-SR04 module, OLED screen, servo, and laser. Using the STM32 microcontroller, the entire system design is compact and has low power consumption. With the help of the MPU6050 gyroscope module, it can measure the device’s posture, acceleration, and temperature in real-time. This allows users to view the posture information and temperature on the screen. At the same time, the posture information controls the servo posture in real-time, allowing it to scan to any angle. Using the HC-SR04 ultrasonic module, this digital thermometer can measure the distance to objects, allowing users to understand the distance between objects in the environment and the device and obtain corresponding distance information from the screen. By adopting an OLED screen, users can clearly see temperature, posture, distance, and other related information on the screen. The OLED screen features high contrast, low power consumption, and fast response, providing good visibility. By integrating these modules and components, the STM32-based laser distance meter provides an accurate solution for temperature measurement, posture measurement, distance measurement, visual display, and additional functions. It can be widely used in indoor temperature monitoring, device posture detection, distance measurement, and other embedded application scenarios.

Project Five

Project Name: STM32-based Digital Thermometer

Project Source: Course Project “Embedded System Design”

Instructor: Sun Lifei

Student Team: 21003390103 2100339120

Project Introduction

Based on STM32 as the main control board, NTC thermistor temperature measurement: through ADC conversion and related calculations, the system can obtain and process the resistance change of the thermistor in real-time to obtain accurate temperature data.

Bluetooth transmission: using the DO4.0 Bluetooth module, the system transmits temperature data in real-time to connected mobile phones or other devices for remote monitoring and recording.

Serial display: through the serial assistant, users can view temperature data in real-time on the serial port, facilitating integration with other systems or devices.

Button operation: three buttons are used to switch temperature units (Celsius/Fahrenheit), increase temperature, and decrease temperature, making the operation simple and intuitive.

Three-color light display: based on the current temperature, the system automatically adjusts the display color of the three-color light (green indicates normal range, blue indicates high-temperature warning, red indicates low-temperature warning).

During the testing process, we found that the system’s accuracy and stability performed well. Specifically, the temperature detection error is within ±0.5℃, and it performs stably in multiple repeated tests. Bluetooth transmission is also very reliable, with data transmission speed and stability meeting expected requirements. In addition, the user interface (including buttons and three-color lights) also performed excellently in terms of operability and feedback. Furthermore, our temperature detection system has the advantage of low power consumption. To achieve this goal, we have taken a series of measures in hardware design and software optimization.
