| Abstract: | A temperature measure and control system based on microcontroller AT89C51 is introduced in this paper. In view of the characteristics of the different PID parameters with the different temperature,one kind of scheme is provided which sets multipacket PID parameters in advance,and selects appropriate PID parameters to control on the basis of the measured temperature. The measuring and controlling functions can be selected with keyboard. The PID parameters can be modified on line and in real time. It has the advantages of convenient operation,high-control accuracy and good reliability. It is suitable for the use in lab and on site. |
