彩灯循环控制电路

哈尔滨工业大学华德应用技术学院本科毕业设计（论文）I摘要人们在日常生活、欢乐节日、娱乐及科研中，到处都会遇到装饰问题，总离不开彩灯控制器。彩灯控制电路的不断完善，使得人们的生活更加丰富多彩。本文主要介绍彩灯循环控制电路的设计组成及工作原理。电路中的220V电压通过可控硅器件加至各路彩灯的两端，当可控硅导通时彩灯被点亮，否则熄灭。可控硅的导通与否是由其控制极是否加入触发信号来决定的。这些触发信号由移位寄存器产生的顺序脉冲给出。振荡电路产生的时钟脉冲送入移位寄存器，随着时钟脉冲的不断输入，移位寄存器的各输出端依次变为高（低）电平，形成时序控制信号。时序控制信号经驱动电路送入可控硅，使可控硅依次导通，于是各彩灯被依次点亮（熄灭）。关键词彩灯控制器；时钟脉冲；循环显示；可控硅哈尔滨工业大学华德应用技术学院本科毕业设计（论文）IIAbstractThepeopleinthedailylife,thehappyholiday,theentertainmentandthescientificresearch,everywherecanmeetthedecorationquestion,alwayscannotleavethecoloredlanterncontroller.Thecoloredlanterncontrolcircuit'sunceasingconsummation,causespeople'slifetobemorerichlycolorful.Thistopicmainlyintroducesthecoloredlanterncycliccontrolelectriccircuit'sdesigncompositionandtheprincipleofwork.Inelectriccircuit's220Vvoltageaddsthroughthesilicon-controlledrectifiercomponenttoeachgroupcoloredlantern'sbothsides,whensilicon-controlledrectifierbreakoverthecoloredlanternislightened,otherwiseextinguishes.Silicon-controlledrectifier'sbreakoverornotisbyitscontrolwhetherextremelytojointhetriggerpiptodecide.Thesetriggerpipthesmoothpulsewhichproducesbytheshiftregistergives.Theoscillatingcircuitproducestheclockpulsesendsintheshiftregister,alongwithclockpulse'sunceasinginput,shiftregister'svariousout-portsbecomes(low)thelevelhighinturn,formsthesequentialcontrolsignal.Thesequentialcontrolsignalsendsinthesilicon-controlledrectifierafterthedrivingcircuit,causesthesilicon-controlledrectifierinturnbreakover,thereforevariouscoloredlanternsarelightenedinturn(extinguishment).KeywordsColoredlanterncontroller;Clockpulse;Thecirculationdemonstrated;Silicon-controlledrectifier哈尔滨工业大学华德应用技术学院本科毕业设计（论文）III目录摘要................................................................................................................IAbstract..........................................................................................................II第1章绪论...................................................................................................11.1立题目的和意义................................................................................11.2设计任务与要求................................................................................11.2.1课题概述..................................................................................11.2.2技术要求..................................................................................11.2.3设计内容..................................................................................2第2章电路组成与设计................................................................................32.1设计方案与方框图............................................................................32.1.1设计方案..................................................................................32.1.2电路方框图..............................................................................32.2单元电路介绍....................................................................................42.2.1电源电路..................................................................................42.2.2振荡电路..................................................................................42.2.3计数/时序分配电路..................................................................52.2.4模拟电子开关...........................................................................62.2.5移位寄存器..............................................................................72.2.6驱动电路..................................................................................82.2.7可控硅开关电路.....................................................................102.2.8彩灯电路................................................................................102.3本章小结.........................................................................................10第3章整机电路工作原理...........................................................................113.1整机电路工作原理..........................................................................113.1.1彩灯点亮过程.........................................................................113.1.2彩灯熄灭过程.........................................................................123.2本章小结.........................................................................................13第４章元器件选取与计算...........................................................................144.1元器件选取......................................................................................144.1.1电阻器....................................................................................14哈尔滨工业大学华德应用技术学院本科毕业设计（论文）IV4.1.2电位器....................................................................................144.1.3电容器....................................................................................144.1.4半导体二极管.........................................................................154.1.5半导体三极管.........................................................................154.1.6三端稳压器............................................................................154.1.7集成芯片................................................................................154.2元器件选择..
