In recent years, with the rapid development of science and technology, the application of single chip microcomputer in real-time detection and automatic control is more and more extensive. Although it is often used as the core component of single-chip microcomputer system, it is not enough to understand single-chip microcomputer only. Engineers also need to consider the hardware structure to improve the system.

At present, most colleges and universities have built single-chip microcomputer laboratories, equipped with hardware simulation equipment such as experimental boxes. However, the circuit of the experimental box is fixed, and the experimental steps are difficult to change. This is not in line with the rapid development trend of single chip microcomputer technology. It is also not suitable for developing students' ability and creativity. With the introduction of Proteus software simulation technology, this problem can be solved to some extent. Using the simulation experimental platform, more experimental steps can be designed to help students complete autonomous learning. This is an active system construction technology.

Based on the above information, the author designed a temperature alarm system with the functions of automatic temperature monitoring and artificial infrared temperature adjustment. The system is based on the single-chip computer simulation environment. PIC single-chip computer of MICOCHIP Company is used as the main control chip, combined with peripheral infrared sensor, liquid crystal display, temperature sensor, DC motor, heating furnace wire and alarm equipment. The main chip control system and main program are written in C language.

This design has the advantages of reducing cost and increasing practicability. It can be adopted by most institutions of higher education.
