论文题目 智能大厦中央空调多点温 度测量显示报警系统设计 学生姓名 学 号 所属院部 电子与信息工程学院 专 业 电气工程及其自动化 班 级 指导教师 20**年5月 摘 要 而本课题就是主要介绍基于AT89C52单片机和DS18B20数字温度传感器的多点温度测量系统。该系统采用AT89C52单片机分别采集各个点的温度，实现温度显示、报警功能。它以AT89C52单片机作为主控芯片，采用数字温度传感器DS18B20S实现多路温度的检测，测量精度可达到0.5℃。该系统采用LCD1602液晶显示模块，LCD1602作为显示器，可以形象直观的显示测出的温度值。 本文首先在绪论中介绍了此系统的背景及功能。第二章确定设计方案。第三章系统的论述了总体的设计过程，确定了技术指标及器件的选择并且描述了系统的硬件电路设计，确定了技术指标及器件的选择，并且描述了系统硬件电路设计、硬件设计框图及所使用的各种芯片功能与特性。第四章重点剖析了软件设计过程。最后一章中具体论述了系统的调试步骤和应注意的问题。基于AT89C52单片机的单总线多点温度测控系统具有硬件组成简单、多点温度检测、读数方便、精度高、测温范围广等特点，在实际工程中得出到了广泛的应用。 关 键 词：数字温度计DS18B20; AT89C52; 单总线； 多点测温 ABSTRACT The problem mainly introduces AT89C52 singlechip and DS18B20 temperature sensor that based multiple spot temperature measurememnt system. This system make use of AT89C52 singlechip measuring temperatures about different places. At the same time the system can realize temperature display and alarm function. Of course the AT89C52 MCU is used as control chip.digital temperature sensor DS18B20 realization of muli-channel temperayure detection, It’s measurement accuracy can reach 0.5℃. The display module is made up of LCD1602 liquid crystal display modules. LCD1602 as a display, can make temperature display visually and sightly. This article introduce the fuction of this system firstly.as well as introduce the background feature of the system. The second chapter ensure the design blue print basically. The third chapter discusses the overall design process by the numbers,and ensure the technical specificationsthe,choices of devices and the description of the hardware circuit design. Make certain the diagram used in a variety of modules and functions of chips at the same time. The fourth chapter analyzes the software design prosess pivotly. The final chapter discusses the debug process concretely and what that we should notice.
