| Abstract: | The structures of a temperature control system based on the AT89S52 single chip Microcomputer（SCM） is introduced,and the hardware composition and the software design are described.The limiting processing、parameter tuning and implementation process of PID control algorithm are presented.Innovation point is using touch-screen control system to achieve the functionality.The system can set for a given temperature,shows the real-time temperature 、PID parameters、 real-time temperature curve through the touch screen.It also can collect data,process data,control output.Finally the touch screen displays a good temperature control curve,and achieve a constant temperature control of furnace temperature. |
