基于单片机的智能温度检测器的设计

摘 要

本设计研究基于单片机的智能温度检测器，旨在通过单片机及温度传感器实现自动检测报警功能。设计中首先对其背景及意义进行叙述切入主题，然后对整个系统的硬件设计和软件设计以及软件调试设计重点分析，其中在硬件设计中还分别对其所选器件做了一个简单的叙述介绍，比如按键，蜂鸣器，LCD1602液晶，DS18B20温度传感器，AT89C51单片机等，最后再对这一设计进行一个总结。设计中使用4个按键组成独立按键进行对温度上下限的设定，采用无源蜂鸣器作为报警装置。整个系统使用LCD1602液晶作为显示装置，实时显示检测温度和设定的上下限值。本系统硬件结构简单，操作灵活，以高级语言C语言开发，KEIL4程序开发软件为开发工具设计而成。

The design of intelligent temperature detector based

on single-chip microcomputer

ABSTRACT

The design of intelligent temperature detector based on MCU, to achieve automatic detection by the microcontroller and temperature sensor alarm function. The design of the first described the background and significance of the subject, then the system hardware design and software design and debugging software design focuses on the analysis, which in the hardware design of the device are selected to do a simple narrative, such as buttons, buzzer, LCD1602 LCD, DS18B20 temperature sensor, AT89C51 SCM, then the design of a summary. The 4 key components used in the design of key independent temperature limit setting, using passive buzzer as the alarm device. The whole system using LCD1602 as a liquid crystal display device, display real-time temperature detection and set limit on the value of. The hardware of this system has the advantages of simple structure, flexible operation, with the language C language development, KEIL4 application development software development tools and design.
