1、 本科毕业论文（设计） 题 目 数字温度计的设计 指导教师 职称 讲师 I 数字温度计的设计 摘要 本文综述了数字温度计的设计与制作过程， 详细介绍了设计制作一个完整的数 字温度计需要做的前期准备和制作过程。 通过对题目的透彻理解以及所要设计的 产品的各项性能功能，决定用单片机作为控制内核，其次主要用温度传感器 DS18B20，及其他主要电路配合下设计出一套完整的硬件系统和一套满足设计要 求的软件系统，最后得到了一款基于 AT89S52 单片机控制的数字温度计。本温度 计属于多功能温度计，设计不仅实现了用 LCD1602 显示器显示温度，而且可以同 步显示时间日历，日期和时间都可通过按键校整，
2、以及可以设置上下报警温度， 当温度不再设置范围内时，可以报警。 关键词关键词：AT89S52 单片机；数字温度传感器 DS18B20；显示器 LCD1602； II THE DIGITAL THERMOMETER DESIGN Abstract Digital thermometer was reviewed in this paper the design and manufacture process, detailed introduces the design of a complete digital thermometer need to do preparation and pr
3、oduction process. Through the thorough understanding of subject and the design products of various performance function, decided to use single chip microcomputer as control core, second main use temperature sensor DS18B20, and other main circuit design with a complete set of hardware system and a se
4、t of software system to meet the design requirements, and finally got a AT89S52 SCM control based on the digital thermometer. The thermometer belongs to the multi-function thermometer, designed with LCD1602 display shows temperature and time to modify functions, the year, month, day and week display function and can be set up and down the temperature alarm, when the temperature is no longer set range, you can call the police. KEY WORDS：AT89S52 single-chip microcomputer;
