摘要
随着人们物质生活水平的提高和科学技术的快速发展,采用微型控制器单片机控制是一个好的方向,它所带来的便利是我们大家有目共睹的,在此数字体温计就是一个非常典型的例子,但人们对它的要求越来越高,要做到为工作,科研,生活,提供更便捷的服务,就需要从单片机技术开始,向着数字化控制,智能化控制方向发展。
本设计主要研究了基于单片机的原理而实现的数字体温计。设计分为硬件与软件两部分,其中硬件设计部分由数据采集模块,数据处理模块,体温显示模块,按键及报警模块,电源模块组成。采用C51语言进行编程,设计软件流程,通过调用各个子程序来实现体温计的功能。该设计应用单片机技术,实现了整体电路的设计及数据采集模块,数据处理模块,显示模块的整合,该设计可以实时监测体温,减少医务人员的工作负担。
数字体温计在设计上主要体现方便实用的特点,操作起来简单,在很大程度上减少因测体温带来的一些不必要的麻烦,可以提高医护人员的工作效率,从而减少因测温不准确带来一系列问题。该数字体温计与平时我们使用的体温计相比,具有测温范围广,读数准确方便,并且携带方便,不易破碎,精度高,最重要的是节能环保。

Abstract
With the development of the people’s livelihood and the science technology, to use the single chip puter control is one of the goals that most people pursue. It is no doubt that the MCU contributes a lot to people’s life of which the digital thermometer is the most typical example. With the increasing demand for digital thermometer, people need to start by the single-chip puter technology to provide more convenient facilities for people’s work, science technology, as well as their life and to develop the technology in the direction of digital control and the intelligent control.
The design of this paper focus on the digital thermometer based on the fundamentals of 51-Mono-puters. With the two parts of hardware and software, the former part was made up by data acquisition module, data processing module, temperature display module, key and alert module as well as the power module. On the other hand, the whole process of designing the software is to implement the thermometer function by calling each subroutine in light of the C51 programming language. data acquisition module, data processing module and the display module in application of the single-chip puter technology which can also monitor the body temperature all the time and reduce the burden of the medical staff.
On the whole, the digital t
