文档介绍：摘要
温度作为人类生产生活中常用的被控参数之一,其变化对我们有着重要影响。无论是我们工业生产中广泛使用的反应炉、加热炉,还是我们日常生活中常用的烘干箱、电热水器、微波炉,都对温度的控制和检测有很高的要求。
本课题设计了烘干箱温度控制及其显示系统。本设计中通过单线式温度传感器DS18B20进行温度检测,并将检测数据送入核心处理器AT89C51进行数据处理,温度的控制调整由双向可控硅、键盘、核心处理器协调工作完成,并将最终温度通过四位一体数码管显示。采用MCS-51系列单片机作为核心处理器控制方便、灵活,并且能够很大程度上提高温度控制技术指标。

Abstract
Temperature monly used as one of control parameters in the production of human beings’ life and its changes is very important. Whether the reaction furnace and the heating furnace that are widely used in industrial production, or the oven, the electric water heater, the microwave that monly used in our daily life, all need temperature control and testing.
In this paper, a drying case temperature control and display system is designed. This design is to detect the temperature with the single line type temperature sensor DS18B20, and the test data is taken into core processor AT89C51 for processing. The control and the adjustment of the temperature pleted by the TRIAC, the keyboard, the core processor coordination work. And the result will be displayed on the four-in-one digital tube. This design which uses the MCS-51 single chip puter is convenient and flexible, also it can greatly increase the temperature control technology index.
Keywords:microcontroller drying case temperature control
