毕业设计说明书(论文)中文摘要
电阻炉是热处理行业广泛应用的一种加热炉。该电阻炉的炉温范围为0℃~1200℃,系统主要调节在1000℃左右,精度达±5℃。一般加热过程中会出现温度与显示不一致的情况,导致工件加热不均匀产品质量不高的问题出现。为了克服人工干预、自动化程度不高的缺点,此设计采用以八位的单片机AT89C52为核心部件的控制系统,对被控对象的温度采用PID参数可调的实时控制。系统应用程序由结构化模块实现,以实现温区温度上升达到设定值后进行长时间保温的目的。

Title The Design of Temperature Controller for
Resistance Furnace Based on AT89C52
Abstract
Resistance furnace is one of heating furnaces, which are widely used in heat treatment industry. The temperature range of the resistance furnace is 0℃~1200℃, the adjustment about 1000℃, accuracy to±5℃。It is general to heat the process the inside will appear the temperature and show the inconsistent circumstance,which cause workplace to be heated up roughly ,and at the same time ,the product quality problem will appear. Because the artificial intervention automation level is not high , so automatic control system is brought to surmount the ing . In the design, single chip puter AT89C52 as a core control portion can help realize the inner temperature real time control, adopt PID algorithm. The applying programming of system is realized by structured modular. so as to realize temperature control—achieve the temperature of two temperature areas rise synchronously and when the temperature reach setting value , e into the long process of heat preservation.
