綠色照明系統(tǒng)設(shè)計(jì)摘要本設(shè)計(jì)針對的是教室燈光控制，通過對教室環(huán)境調(diào)查，給出了節(jié)約電能實(shí)現(xiàn)與控制方法，即基于單片機(jī)的綠色照明系統(tǒng)設(shè)計(jì)。該系統(tǒng)以單片機(jī)作為主控制器，采用光敏電阻模塊檢測教室自然光強(qiáng)度，根據(jù)環(huán)境光照強(qiáng)度對燈光進(jìn)行分級控制。采用熱釋紅外傳感器檢測并統(tǒng)計(jì)人數(shù)，以此對教室燈具進(jìn)行分組控制，系統(tǒng)再綜合光照強(qiáng)度及室內(nèi)人數(shù)進(jìn)行識別和判斷，從而控制燈具的具體開關(guān)盞數(shù)。系統(tǒng)可以晚上提醒學(xué)生離開教室，定時(shí)對教室燈光進(jìn)行集中管理，其定時(shí)關(guān)燈時(shí)間可根據(jù)具體作息時(shí)間進(jìn)行調(diào)整。在寒暑假等較長假期可以設(shè)定某些月份關(guān)閉照明系統(tǒng)。另外系統(tǒng)通過使用節(jié)能LED,使整個(gè)系統(tǒng)更加節(jié)能。關(guān)鍵詞分組控制，白光LED，定時(shí)控制，傳感器ABSTRACTThisdesignisaimedprimarilyattheclassroomlightingcontrol,classroomenvironmentsurvey,giventheenergysavingsachievedwiththecontrolmethod,whichisbasedonmicrocontrollergreenlightingsystemdesign.Thesystemmicrocontrollerasthemaincontroller,thethephotoresistormoduledetectsclassroomnaturallightintensityaccordingtotheambientlightintensitylightinghierarchicalcontrol.Pyroelectricinfraredsensorstodetectanddeterminethespecificlocationofthepeople,inordertogroupclassroomlightingcontrolsystemandthenintegratedlightintensityandthenumberofindooridentifyandjudge,soastocontrolthelightingswitchlamp.Thesystemcanremindstudentstoleavetheclassroom,regularclassroomlightingforcentralizedmanagement,thetiminglightsareturnedofftimecanbeadjustedaccordingtothespecificworkschedules.Shutdownthelightingsystemcansetsomemonthsinthewinterandsummervacationsandlongerholidays.Inaddition,thesystemthroughtheuseofenergy-efficientLEDtomakethewholesystemmoreenergyefficient.KeyWords：Packetcontrol,ThewhiteLED,Thetimingcontrol,Thesensor目錄TOC\o"1-3"\h\u94871.緒論 附錄電氣原理圖程序#include<reg52.h>#include<string.h>#defineucharunsignedchar#defineuintunsignedintsbitzhuan=P2^0;sbitsound=P2^1;sbitSDA=P1^7;sbitCLK=P1^6;sbitRST=P1^5;sbitRS=P2^5;sbitRW=P2^6;sbitEN=P2^7;sbitk1=P3^4;sbitk2=P3^5;sbitk3=P3^6;sbitk4=P3^7;ucharcodedis_alarm0[]="ALARMMHM";uchardis_alarm1[]="TM:00:00:00"ucharyue=0;ucharshi=0;ucharfen=0;uchartcount=0;ucharmonthdays[]={0,31,0,31,30,31,30,31,31,30,31,30,31};uchar*week[]={"sun","mon","tus","wen","thu","fri","sat"};ucharidatalcd_dis_buffer1[]={"DT:2000-00-00"};ucharidatalcd_dis_buffer2[]={"TM:00:00:00"};uchardatetime[7];ucharadjust_index=-1;ucharchange_flag[]="-MHDM-Y";
