摘 要
随着社会的发展，单片机因其高可靠性和高性价比，在工业控制系统、 智能化仪器仪表和智能接口等诸多领域内得到了极为广泛的应用。
基于单片机控制的电阻炉温控制系统是一种智能型控制系统。该系统由8031单片机及其复位电路，晶振电路，总线收发电路，译码电路，温度传感器与系数接口，显示电路，存储器及接口电路组成控制器，以温度为被控制量的闭环控制系统，适用于大功率的电阻锅炉。一种基于单片机的大动态范围、温度传感器的设计研制，将被测温度信号由模拟量转换为数字量，利用单片机系统达到高精度的要求，整个系统有非线性校正、LED显示和键盘输入等功能。

Abstract
With the development of society, Single-Chip Microcomputer gains wide applications in industry control system, intelligent interface, intelligent instruments and office automation system so on, for its higher reliability and cost performance.
In this papers, the temperature control system of electric stove is a intelligent control system。The control system includes the 8031 single chip microprocessor and Circuits of restituting position，circuits of exportation and importation, Circuits of translation code, transmission and induction system of temperature, the interface of coefficient, circuits of showing, stashing equipment and circuits of interface. The temperature is the controlled variable and a closed loop system is constructed. The designed system is available for automatic equipment of electricity and caloric. A design and research that make mensurated signal from simulation to digital amount, which transmission and induction system of temperature, can reach to the request of accuracy with the Single Chip microprocessor. The System include un-linear correction, compensation about temperature many points. Some function of LED showing and keyboard input

摘 要
随着社会的发展，单片机因其高可靠性和高性价比，在工业控制系统、 智能化仪器仪表和智能接口等诸多领域内得到了极为广泛的应用。
基于单片机控制的电阻炉温控制系统是一种智能型控制系统。该系统由8031单片机及其复位电路，晶振电路，总线收发电路，译码电路，温度传感器与系数接口，显示电路，存储器及接口电路组成控制器，以温度为被控制量的闭环控制系统，适用于大功率的电阻锅炉。一种基于单片机的大动态范围、温度传感器的设计研制，将被测温度信号由模拟量转换为数字量，利用单片机系统达到高精度的要求，整个系统有非线性校正、LED显示和键盘输入等功能。
