摘要

本文首先介绍了智能家居的基本知识及其应用前景，进而阐明了开发作为智能家居中一个很重要部分—红外线遥控推拉窗及窗帘的控制意义，随后着重介绍了开发单片机的红外线遥控智能控制系统设计所用到的集成芯片AT89C52、DS1302芯片、红外线发射接收器等硬件的结构原理。本文采用分块的模式，对整个系统的硬件电路设计进行分析，分别给出了系统总体框图、电源电路、时钟DS1302电路、红外线接收电路、电机控制电路、显示电路，下雨传感器电路、并对相应电路设计进行了相关的阐述。随后讲述了软件的编写思路，也是采用分块的模式，分别写出了红外线解码程序、时钟芯片DS1302控制程序、LCD液晶显示程序、遥控控制程序的编写思路，每一模块都画出了其方框图，看起来一目了然。

最后通过仿真调试，时钟，手动开关窗帘，自动开关窗帘等控制方面的设计上基本达到了预期目的。当然，该系统在一些细节的设计上还需要不断的完善和改进。

Abstract

This paper first introduced the basic knowledge of the smart home and its application prospect, thus illustrating the development as wisdom can household a very important part of the curtain, automatic infrared remote control significance. Then mainly introduces development single-chip microcomputer control system of infrared remote control curtain use AT89C52 integrated chips, DS1302 chip, infrared emission receiver and the structure of the hardware principle. In this article, the block model, the whole system hardware circuit design is analyzed, and the system are respectively the overall frame, power supply circuit, the clock DS1302 circuit, infrared receiver circuits, motor control circuit, show circuit, rain sensor circuit, and to the corresponding circuit design and the correlation of exposition. Then the writing of the ideas about software, is also the separate block of models, including the decoding process, Write the decoding process of infrared ray respectively, the clock chip DS1302 control procedures, LCD display program, remote control of control program writing ideas, each module are draw the charts, looks at a glance.

Finally, the simulation results debugging, clock, the switch curtain, automatic switch control aspects such as the curtain on the design of basic the expected purpose is reached. Of course, this system in some of the detail of the design also need to have been the perfect and improve. Keywords: the clock chip；Intelligent control；infrared；AT89C52；sensor
