摘 要:本次毕业设计出的数字温度计与传统意义上的温度计相比较,在测温范围、精度以及读数方面存在很大的优势。并且能够手动设置高低报警温度值,测温范围在 -55℃~+125℃之间,精确度为±0.1℃。当测量的环境温度不在设定值之间时,则自动启动温度报警系统。另外,本文也重点讲述了此次设计的硬件与软件的选择和设计过程。其中在硬件的选择上主要选用了STC89C51型单片机、DS18B20型传感器以及LCD1602字符型液晶显示模块;软件的设计主要从设计方案的选择、系统框图的设计出发,首先介绍了本次设计的一个大体思路,然后根据每个模块进行单个分析,最终完成整个设计的全部程序。37149 毕业论文关键词:STC89C51型单片机;温度传感器;液晶显示屏
Digital Thermometer Design
Abstract:Digital thermometer with the traditional thermometer significance of the graduation design of the comparison, there are great advantages in the measurement range, precision and reading. And be able to manually set the high and low alarm temperature value, the temperature range between -55~+125 degrees centigrade accuracy of plus or minus ± 0.1 degrees centigrade. When measuring the ambient temperature is not in the setting, then start automatic temperature alarm system. In addition, this paper also focuses on the process of selection and design of hardware and software of the design. In choosing the hardware mainly uses STC89C51 MCU, DS18B20 sensor and LCD1602 character LCD module; design of software design mainly from the choice of design, system diagram, first introduced the design of a general idea, then according to the analysis of each inpidual module, finally completed the program the design of the.
