Design of Heating Furnace Temperature PID Control System Based on Microprocessor

In order to improve heating furnace of temperature control system, 8031 circuit microprocessor of control system was designed. The hardware design was first given, then, the temperature system, single tablets machine temperature control system, temperature control module, and SCR control circuit were designed. Next, the appropriate part of the procedure was designed. The results show that the temperature control system has the advantage of high precision, little measurement error and high stabilitiy.
