摘要
温度是我们日常生产和生活中实时在接触到的物理量,但是它是看不到
的,仅凭感觉只能感觉到大概的温度值,传统的指针式的温度计虽然能指示温
度,但是精度低,使用不够方便,显示不够直观,数字温度计的出现可以让人
们直观的了解自己想知道的温度到底是多少度。
数字温度计是一种精度高、稳定性好、适用性极强的新型现场温度显示
仪,是传统现场指针式金属温度计的理想替代产品,广泛应用于各类工矿企
业,大专院校,科研院所。
数字温度计采用温度敏感元件也就是温度传感器(如铂电阻,热电偶,半
导体,热敏电阻等),将温度的变化转换成电信号的变化,如电压和电流的变
化,温度变化和电信号的变化有一定的关系,如线性关系,一定的曲线关系
等,这个电信号可以使用模数转换的电路即 AD 转换电路将模拟信号转换为数
字信号,数字信号再送给处理单元,如单片机或者 PC 机等,处理单元经过内
部的软件计算将这个数字信号和温度联系起来,成为可以显示出来的温度数
值,如 LED,LCD 或者电脑屏幕等显示出来给人观察。这样就完成了数字温度
计的基本测温功能。
此次课程设计我们借助 Proteus 软件仿真实现 PT100 测量温度的功能。

Abstract
Temperature is in our daily life and production in real-time access to physical
quantities, but it is invisible, just by feeling can only feel about temperature, although
the traditional pointer thermometer can indicate the temperature, but the precision is
low, use convenient enough, show not intuitive, the emergence of digital thermometer
can let people intuitively understand how much he'd like to know what the temperature
is.
Digital thermometer is a new field temperature indicator with high precision, good
stability and strong applicability. It is an ideal substitute for traditional field pointer
metal thermometer and is widely used in various industrial and mining enterprises,
colleges and universities, and scientific research institutes.
Digital thermometer is a temperature sensitive element temperature sensor (such
as platinum resistance, thermocouple, semiconductor, thermistor, etc.), the temperature
changes of converted into electrical signals, such as the change of the voltage and
current, the temperature change and the change of the electrical signal has a certain
relationship, such as linear relationship, the curve of a certain relationship, such as the
electrical signal can be used in adc circuit that AD conversion circuit converts analog
signals to digital signals, the digital signal to send to processing unit, such as SCM and
PC, processing unit through internal software calculation will be linked to the digital
signal and temperature,
It becomes a temperature value that can be displayed, such as LED,LCD or
computer screen, for people to observe.This completes the basic temperature
measurement function of the digital thermometer.
This course design we use Proteus software simulation to achieve PT100
temperature measurement function.
Key words: voltage acquisition, SCM, MSP430, A/D conversion, PT100
