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

[Key words]: Single Chip microprocessor Control Measuring and Controlling
