基于单片机的空调控制系统的设计.doc

毕 业 设 计 论 文 摘 要 在本文中，系统地介绍了空调制冷的原理、硬件的结构、工作原理及其使用和各部分逻辑功能电路的设计。文中，还解决了单片机系统的抗干扰问题。采用了稳压电源的抗干扰、A/D转换抗干扰以及键盘输入接口的消抖处理。 本文设计的空调制冷系统，它是一个完整的单片机系统。系统采用Intel公司生产的80C51单片机,通过A/D转换器将温度传感器采集来的温度数据送入单片机，单片机将采集的数据与设定温度相比较决定压缩机的工作状态，空调的心脏是压缩机，单片机通过对制冷压缩机的控制，实现了空调的制冷。 关键词： 空调制冷 压缩机 A/D转换器 抗干扰 单片机 Abstract The theory of refrigeration of air-condition, the hardwork structure, working principle and its use and the design of various parts of logic functive circuit was introduced by the numbers in this paper. The question of anti-jamming of Single Chip Micyoco (SCM) was solved. The anti-jamming of regulated electrical source and A/D conversion and the antiquiver treatment of keyboard input interface was used. The refrigeration system of air-condition designed in this paper is a integrated SCM. The 80C51 SCM produced by Intel Company was used, the data collected by temperature sensors was sent to SCM through A/D conversion, then SCM decided the work condition of compressor threugh comparing the data collected with set temperature, the compressor is the heart of air-condition, SCM carried out the refrigeration of air-condition through controling the refrigerative compressor. Key words: refrigeration of air-condition; compressor; A/D conversion; anti-jamming; Single Chip Micyoco． 目 录 前言·····················································································································1 第一章 绪论········································································································1 第一节.........................................................................................................................................1 　一、空调…………………………………………………………………………………...1 二、空调的工作原理………………………………………………………………………1 三、空调的功能……………………………………………………………………………1 第二节 单片机………………………………………………………………..… …………….2 第三节 单片机与空调控制系统................................................................................................3 第二章 基于单片机的空调控制系统设计……………………
