Abstract
The furnace temperature control system is a practical scientific research subject and can be applied in production. The parameters of the system are temperature, and the digital single-chip computer can be used to control the control system. Through this design, students can be familiar with and master the practical application of SCM, and understand the development direction of SCM in the field of modern detection and control.
This design uses single chip computer as the core to monitor and control the temperature of electric heating furnace. Using single chip computer to control them not only has the advantages of convenience, simplicity and flexibility, but also can greatly improve the technical index of the controlled temperature. Thus can greatly improve the quality and quantity of products. The principle and application of single chip computer are studied. The temperature of heating furnace is detected and the result is displayed by display circuit. The application of keystroke and display circuit is studied. The digital PID algorithm is used in temperature control. When the parameter detection value exceeds the rated value ±10, the hardware and software parts of the single-chip computer system are designed. Application of single Chip Microcomputer Group Hardware system, draw the details of the hardware connection (circuit schematic diagram). Complete the software design of the course, submit the program design block diagram and program list. On the basis of software and hardware design, the corresponding MCU system simulation is done.
Key words: reheating furnace; furnace temperature control; PID; MCU; simulation
