路灯节能系统设计

摘要随着社会文明和科技的不断发展，城市道路照明已经成为各市政府极为关心的市政形象工程。在城市照明系统中，如何节约能源，提高路灯能源的利用率已成为急需解决的问题。因此，提供一种于路灯远程监控有效而合理的管理方法，对城市建设显得极为重要。本系统设计一个基于AT89S52单片机的路灯节能系统的下位机的实现，运用PTR4000+模块实现无线组网；光强传感器采集光照强度，当光强达到一定阈值，关闭路灯；超声波采集路况，来达到调整路灯的发光强度；温度传感器采集电路板温度，达到检测报错的效果；最终达到设计中使用Keil环境编写C代码；运用仿真软件Proteus分模块实现仿真来验证程序；使用AltiumDesignerSummer设计原理图；并绘制PCB板进行实物调试；达到快速开发的效果。关键词:智能路灯；单片机；无线通信2.4G；苏州经贸职业技术学院2/73AbstractWiththecontinuoussocialcivilizationandtechnologydevelopment,urbanroadlightinghasbecomeofgreatinteresttothemunicipalgovernmentimageprojects.Lightingsysteminthecity,howtosaveenergy,improveenergyefficiencylamphasbecomeanurgentproblem.Therefore,toprovidearemotemonitoringinthestreeteffectiveandreasonablemanagementofurbanconstructionisextremelyimportant.ThesystemdesignasinglechipAT89S52-basedenergysysteminthelowerstreetmachinesandendtherealizationofthewirelessnetworkusingthewirelessnetworkPTR4000+modules;Lightintensitysensorscollectlightintensity,whenthelightintensityreachesacertainthreshold,closestreet;ultrasonicacquisitionroadconditions,toachievetheadjustmentoftheluminousintensityoflights;temperaturesensoracquisitionboardtemperature,totesttheeffectoferror.DesignenvironmentwrittenusingKeilCcode;theuseofsub-moduleofsimulationsoftwaresimulationsProteusverificationprocedures;useofAltiumDesignerSummerdesignschematics;andthemappingofthephysicalPCBboarddebug;achieverapiddevelopmentresults.Keywords:intelligentlights;MCU;2.4Gwirelesscommunication苏州经贸职业技术学院3/73目录第一章绪论..................................................................................................................................51.1概论........................................................................................................................................51.2背景........................................................................................................................................51.3课题研究的目的及意义........................................................................................................7第二章路灯节能系统的设计方案................................................................................................82.1路灯节能系统设计总体框架构思........................................................................................82.2路灯节能系统框架结构........................................................................................................82.3路灯节能系统方案选择........................................................................................................92.4路灯节能系统具体设计框图..............................................................................................16第三章路灯节能系统的硬件电路设计......................................................................................173.1AT89S52单片机简介..........................................................................................................173.2单片机系统电路.................................................................................................................223.3串口下载与通信电路..........................................................................................................243.4温度采集检测电路.............................................................................................................263.5光照强度采集电路..............................................................................................................273.6A/D转换电路......................................................................................................................293.7D/A转换（AD557）电路...................................................................................................313.8超声波检测电路.................................................................................................................323.9无线通信模块电路..............................................................................................................353.10显示电路............................................................................................................................40第四章路灯节能系统的软件程序设计......................................................................................424.1路灯节能系统主流程图......................................................................................................424.2DS18B20温度采集流程图..................................................................................................424.3AD549模数转换流程图......................................................................................................434.4AD557数模转换流程图......................................................................................................434.5超声波流程图......................................................................................................................444.6无线通信流程图..................................................................................................................444.7数码管显示流程图..............................................................................................................45第五章路灯节能系统软件介绍..................................................................................................465.1C语言简介...........................
