1、 1 红外线遥控电风扇 摘 要 作为传统的家用电器，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、调速功能已经不能满足市场的需求。人们希望电风扇在体积小、作方 便等的基础上能够拥有更多的功能，而红外遥控的广泛应用及单片机技术的成熟，则 使得智能红外遥控系统成为了电风扇的发展趋势。 本设计方案基于市场的需求，结合红外遥控设计简单、作方便、成本低廉等特点，采 用了专用的遥控发射接收芯片， 在此基础上设计了一个简易的智能红外遥控电风扇系 统。系统包括接收和发射两大部分，本文设计实现了几项电风扇的基本功能：开/关 功能、三级调速功能、0.5-7.5 小时不同时间段的定时功能，以及自
2、然、正常两种风 类的选择功能。经过多次的测试与电路调整，系统的各项功能均能正常实现。 关键字：红外遥控；信号调制；编码；解码；双向可控硅 Infrared remote control fan 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
3、 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 technologies of SCM become mature, the smart infrared remote co
4、ntrol system is the trend. 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 2 designed to achieve some basic functions of fans: on / off function, three kin
