摘 要

隨著社會的發(fā)展，單片機因其高可靠性和高性價比，在工業(yè)控制系統(tǒng)、 智能化儀器儀表和智能接口等諸多領域內得到了極為廣泛的應用。
基于單片機控制的電阻爐溫控制系統(tǒng)是一種智能型控制系統(tǒng)。該系統(tǒng)由8031單片機及其復位電路，晶振電路，總線收發(fā)電路，譯碼電路，溫度傳感器與系數(shù)接口，顯示電路，存儲器及接口電路組成控制器，以溫度為被控制量的閉環(huán)控制系統(tǒng)，適用于大功率的電阻鍋爐。一種基于單片機的大動態(tài)范圍、溫度傳感器的設計研制，將被測溫度信號由模擬量轉換為數(shù)字量，利用單片機系統(tǒng)達到高精度的要求，整個系統(tǒng)有非線性校正、LED顯示和鍵盤輸入等功能。

【關鍵詞】單片機控制，溫度測量與控制，單片機

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
