兰州工业学院毕业设计说明书（论文）摘要本文介绍了一个模拟路灯控制系统的应用方案，用以实现模拟路灯的智能控制。本方案以AT89S52为核心，加以简单的外围电路，实现了模拟路灯控制系统所要求的全部技术内容。单片机在最近几年应用越来越广泛，因其抗干扰能力强、稳定性好，性价比高，因此是低成本路灯控制解决方案的首选。该控制系统除了选用廉价的单片机芯片，还采用了廉价的红外对射传感器，大大降低了系统成本。整个系统的电路简单，结构紧凑,电源驱动仅采用变压器与三端稳压器相结合，附加少许滤波电容便实现了稳定的电源输出。经过多次测试，证实该系统能长时间稳定工作，完全满足设计要求指标。关键词：模拟控制；LED照明；单片机ABSTRACTThispaperintroducesasimulationcontrolsystemapplicationschemestreet,tosimulatethestreetlampofintelligentcontrol.Thisplantomacrocrystal1兰州工业学院毕业设计说明书（论文）companyAT89S52asthecore,tochiptheperipheryofthesimplecircuit,realizethesimulationstreetlampcontrolsystemalloftherequestedtechnologycontent.STCSCMinrecentyearsmoreandmorewideapplication,becauseofitsstronganti-interferenceability,goodstability,highperformance/priceratio,andsoisthelowcoststreetlampcontrolsolutionsofchoice.Thecontrolsysteminadditiontochoosecheapsingle-chipmicrocomputerchip,alsoadoptedthecheapinfraredmutualilluminatesensor,andgreatlyreducethecostofsystem.Thewholesystemofthecircuitissimple,compactstructure,powerdriveonlyusedthreetransformerandtheregulators,andthecombinationofafewadditionalfiltercapacitancewillrealizethestablepoweroutput.Aftermanytest,andconfirmthatthesystemcanworkstablyforalongtime,fullymeetthedesignrequirementsindex.Keywords:Simulatecontrolling;LEDlighting;Single-chipmicrocomputer目录第一章绪论.............................................................51.1．0概述........................................................51.1.1论文的题目....................................................51.1.2研究的背景....................................................51.1.3研究的目的及意义..............................................51.2.0国内发展现状与趋势............................................61.3.0研究内容......................................................6第二章系统总体设计方案................................................92.1.0系统设计思路与方案比较论证....................................92.1.1系统设计思路..................................................92.1.2方案论证与确立................................................92兰州工业学院毕业设计说明书（论文）第三章系统硬件设计...................................................132.2.0各个模块的硬件电路设计.......................................132.2.1时钟模块设计.................................................132.2.3主控制模块设计...............................................142.2.4单片机AT89S52芯片介绍......................................142.2.4显示模块设计.................................................172.3.0系统各模块的最终方案.........................................192.4.0系统功能说明书...............................................202.4.1路灯的工作模式...............................................20第四章软件设计.......................................................243.1.0系统主程序流程图.............................................243.1.1系统流程图...................................................243.2.0定时器溢出中断处理函数流程图.................................253.3.0按键扫描流程图............................................
