基于单片机的温度控制与红外遥控实验设计详解

The experiment on designing a temperature controller based on a single-chip microcomputer is a comprehensive practical project conducted by the student XXX from the Electrical and Information Engineering College of Panzhihua University. The experiment focuses on implementing a fan Infrared remote control circuit using a single-chip microcomputer. The AT89C52 single-chip microcomputer is used as the core to control the temperature system. The temperature signal is acquired by the DS18B20 temperature sensor and transmitted to the single-chip microcomputer in digital form. The hardware components of the control system include the temperature detection circuit, temperature control circuit, PC and single-chip microcomputer serial communication circuit, and various interface circuits. By processing the signals accordingly, the single-chip microcomputer achieves the goal of temperature control. The software design part is emphasized in the experiment, adopting a modular structure. Key modules include the seven-segment LED display program, keyboard scanning and key processing program, temperature signal processing program, relay control program, and over-temperature alarm program. In summary, the experiment illustrates the working principle and design methodology of a temperature control system based on a single-chip microcontroller. Through a combination of hardware setup and software programming, the system effectively controls temperature using the data collected from the temperature sensor. This practical project is both educational and practical, providing students with hands-on experience in designing electronic systems and implementing control mechanisms.
