Abstract

With the development of national economy, people need to monitor and control the temperature of medium heating furnace, heat treatment furnace, reaction furnace and boiler. MCU to use them to control is not only easy to control, simple and flexible and other advantages, and can greatly increase the temperature was charged with the technical indicators, which can greatly improve the quality and quantity of products.

The system to AT89C51, AT89C2051 microcontroller as the core, including sensor temperature acquisition, A/D mode / number conversion, single-chip control, digital display and other digital part. The system uses PID algorithm to achieve temperature control function, through the serial communication to complete the interaction of two pieces of SCM information to achieve temperature settings, control and display. In order to realize high precision temperature control, the SCM system adopts PID control algorithm and PWM pulse width modulation technology combined by controlling the on and power supply and a bidirectional thyristor is disconnected, thereby changing the temperature of the heating time method to achieve control of water temperature. The system is
