Abstract

In order to meet the teaching needs, the experimental design of temperature regulation based on PWN of STC15 microcomputer is designed to teach the application and temperature control principle of single-chip microcomputer. The system uses the STC15 microcontroller to monitor the temperature value in real time through the NEC protocol, and uses the PWM function to adjust the heater power to control the temperature accurately. The experiment uses two STC15 microcontrollers with infrared transceiver modules, allowing students to communicate between devices via CAN bus. At the same time, the single-chip microcomputer is also connected to the PC side, uploading temperature data and control results to the PC side, and receiving instructions and management messages issued by the PC for monitoring and operation, thereby driving temperature control experiments and viewing experimental results. Real-time, flexible and easy to operate, the system can effectively assist teaching and provide a platform for communication and collaboration between students and teachers.
