摘　　要：综合常规PID控制和专家系统的优点,设计了导热系数测定仪智能温度控制系统。它是以C8051F020单片机为核心进行温度信息的采集、数据运算与温度的控制,具有汉字液晶显示、实时时钟、和计算机通讯等功能。文中简述了设计方法,对几个关键技术问题进行了详细论述。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.
