| Abstract: | By synthesizing the advantages of conventional PID control strategy and expert system strategy, an intelligent temperature control system for instrument of measuring the thermal conductivity has been designed. Based on C8051F020 Mixed - Signal microcontrollers, it can be used for gathering temperature signals, processing data and controlling temperature, it has also other functions, such as： liquid crystal Chinese characters display, real time clock and communication with computer , etc. In this paper, designing method is simply introduced; several key technical problems are described in detail. |
