摘要
随着科技的不断发展,电子设备的应用已经取得了非凡的成就。即使是高度集成化的今天,单片机技术依旧在我们的日常生活中占据着重要的地位。温度是日常生活、工业、医学、环境保护、化工、石油等领域最常用到的一个物理量。测量温度的基本方法是使用温度计直接读取温度。最常见到得测量温度的工具是各种各样的温度计。它们常常以刻度的形式表示温度的高低,人们必须通过读取刻度值的多少来测量温度。利用单片机和温度传感器构成的电子式智能温度计就可以直接测量温度,得到温度的数字值,既简单方便,有直观准确。本文讲叙了一种基于51系列单片机的数字温度计的设计过程与仿真结果。通过Proteus画图以及Keil编程,成功的仿真出了能够实时测量温度并显示温度的数字温度计,另外还能够通过外接的键盘设置一个基准值,若温度高于基准值则会报警并且发出控制动作。

Abstract
With the continuous development of science and technology,the application of electronic equipment has made remarkable the highly integrated single-chip technology today,still in our daily life plays an important role is the daily life, industry, medicine, environmental protection,chemical industry,petroleum and other areas of the monly used of a physical measurement is the basic method used to directly read temperature mon to measuring the temperature of the tool is various often graduated form high and low temperature,people must read through the scale value number to measure single puter and a temperature electronic type intelligent thermometer can measure temperature,the temperature of the digital values,are simple and convenient,is intuitive and article tells of a microcontroller based on the Series 51 digital thermometer's design process and simulation the Proteus drawing and keil programming,a essful simulation of a real-time temperature measurement and display the temperature of the digital thermometer,also can pass through an external keyboard to set a baseline value,if the temperature is higher than the reference value can alarm and send out the feedback action.
