摘要目前，电风扇的使用十分广泛，面对庞大的市场需求，我们需要提高电风扇的市场竞争力，使之不仅功能多样、安全可靠，而且操作简便；而单片机因其高可靠性和高性价比，在智能化家用电器、仪器仪表等诸多领域得到了极为广泛的应用。因此，基于单片机技术设计一款电风扇遥控开关是大有必要的，不仅方便而且智能化。本设计是基于STC89C52单片机控制的智能电风扇遥控开关，巧妙地利用红外线遥控技术、单片机控制技术、液晶显示电路，具有一定的遥控距离、4级调速、停止、定时等功能，同时LCD12864液晶显示遥控开关状态、LED显示接收端即电风扇状态。关键词：STC89C52；LCD12864；遥控开关；电风扇AbstractCurrently,theuseofelectricfansisveryextensive.Inthefaceofthehugemarketdemand,weneedtoimprovethemarketcompetitivenessofthefans,sothattheyarenotonlyversatile、safe、reliable,butalsoeasytooperate;yetthemicrocontrollerbecauseofitshighreliabilityandcost-effective,hasbeenverywidelyusedinintelligenthouseholdappliances、instrumentsandmanyotherareas.Therefore,wedesignaremotefanswitchbasedonMCUtechnologyisverynecessary,it’snotonlyconvenientbutalsointelligent.ThedesignofsmartfanremotecontrolswitchbasedontheSTC89C52microcontroller-controlled,cleverusesofinfraredremotecontroltechnology、MCUcontroltechnology、liquidcrystaldisplaycircuit,hasacertaindistanceoftheremotecontrol、4speed、stop、timingetc.Atthesametime,theLCD12864displaysthestatusoftheremotecontrolswitch,andtheLEDdisplaysthereceivingendthatthestatusofthefan.Keywords:STC89C52;LCD12864;remotecontrolswitch;fans目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc356639660"摘要PAGEREF_Toc356639660\hIHYPERLINK\l"_Toc356639661"AbstractPAGEREF_Toc356639661\hIIHYPERLINK\l"_Toc356639662"第1章概述PAGEREF_Toc356639662\h1HYPERLINK\l"_Toc356639663"1.1电风扇遥控开关背景及意义PAGEREF_Toc356639663\h1HYPERLINK\l"_Toc356639664"1.2电风扇遥控开关国内外现状PAGEREF_Toc356639664\h2HYPERLINK\l"_Toc356639665"1.3本文研究的主要内容PAGEREF_Toc356639665\h2HYPERLINK\l"_Toc356639666"第2章系统体系结构PAGEREF_Toc356639666\h4HYPERLINK\l"_Toc356639667"2.1设计方案PAGEREF_Toc356639667\h4HYPERLINK\l"_Toc356639668"2.2系统整体框图设计PAGEREF_Toc356639668\h4HYPERLINK\l"_Toc356639669"第3章系统硬件设计PAGEREF_Toc356639669\h6HYPERLINK\l"_Toc356639670"3.1最小系统模块PAGEREF_Toc356639670\h6HYPERLINK\l"_Toc356639671"3.2按键模块PAGEREF_Toc356639671\h7HYPERLIN
