摘要

电风扇是一种传统的家用电器，但随着空调的普及，电风扇的市场地位受到了巨大的冲击。传统的开/关、调速功能现已不能满足市场的需求，人们希望电风扇能在体积小、操作方便等的基础上拥有更多的功能，而红外遥控的普遍应用及单片机的成熟，使得电风扇的发展趋向于智能红外遥控系统。

本设计方案为满足市场的需求，结合红外遥控系统设计简单、操作方便、成本低廉等特点，运用了51单片机作为遥控发射接收芯片，HS0038为红外一体化接收发射管，设计了一个简易的单片机红外遥控电风扇系统，系统包括接收和发射两大部分。该系统设计实现了几项电风扇的基本功能：开/关功能、多级调速功能、定时功能、自然、正常两种风类的选择功能，此外本系统有16个按键，可用于扩展控制其他电器。

Abstract

ABSTRACT

With the popularity of air conditioners, the market position of the electric fans which are the traditional household appliances will receive a huge impact, the traditional on / off and speed control function have been unfit for the needs of the market. It is hoped that the fans in small, easy to operate, and so on the basis can have more features. When the application of infrared remote control becomes wilder and

The design was based on the needs of the market. Considering that infrared remote control is simple, easy to operate, low-cost, I use a special launching and receiving chip which depends on remote control. On the basis of this chip a system of intelligent infrared remote-control was designed for the fan. The system consists of the launching part and the receiving part. This system is designed to achieve some basic functions of fans: on / off function, three kinds of speed, the timing function which can be chosen at different times of 0.5-7.5 hours, and the function of two kinds of wind which are the natural wind and the normal wind.

Key words: Infrared Remote Control, Signal Modulation, Encoding, Decoding

technologies of SCM become mature, the remote control system is the trend.
