本科生毕业设计（论文）题目：基于Zigbee的智能灯光控制系统设计姓名：冯祥勋学号：11S010900926学院：电气工程与自动化学院专业：电气工程与自动化（自动化方向）年级：2009级指导教师：（签名）2013年05月20日I摘要在现代社会，自动化与智能程度不断提高的今天，家居智能管理必然是人们今后的唯一选择。本文主要研究对象为家庭的照明，在通过比较传统照明方式，研究目前较应用的照明控制中发现家庭照明中往往存在一些致命的问题，如照明控制方式落后，甚至很大程度都还是采用机械开关，安全系数低，舒适性差，布线复杂等。由于这些控制方式上的不足，极大的造成能源的浪费，甚至在控制的误区里出现室内无人，却灯火通明的现象。针对这些不足，需要对控制做一个进一步的研究与开发。本文较全面的研究了传统照明、现代照明的特点，通过比较得出优缺点，提出一种基于Zigbee的无线智能控制方案，即采用两块Zigbee功能板，一块导入光敏传感器和热释红外传感器，用作信号发射，另一块接入继电器模块，接收信号并控制灯光亮灭。在这种控制方式下，只有室内有人，且光线不足时才点亮所需灯光，而在室内无人，光线不足的情况下，灯不亮，采用这样的控制方式能很好解决误开断和能源浪费的问题。论文中详细介绍了整个控制系统的功能和控制策略，软件程序设计包括LED灯初始化、光敏传感器初始化、PIR传感器初始化、协议栈初始化，串口通讯等。最后，在模拟实际环境下，测试可行性与性能。实验证明，采用Zigbee无线控制能有很好的控制效果，并且可以显著提高节能效果，改善“无人灯亮”的问题。关键词：Zigbee，光敏传感器，热释红外传感器，节能IIAbstractWiththeimprovementoftheautomationandintelligenceinthemodernsociety,homeintelligentmanagementinevitablybecomestheonlyoptionforpeopleinthefuture.Bycomparingthetraditionallighting,thispaperdiscoverssomefatalproblemsonthecontrolofhomelighting,suchasbackwardwayoflightingcontrol,namely,mechanicalswitch,whichhaslowcoefficientofsafety,poorcomfortablityandcomplexwiring.Theseshortagesresultingreatwasteofenergyaswellasnobodyappearsbutbrightlylightedinmistakenarea.Inordertomakeupthesedeficiencies,itneedstomakeafurtherresearchonthecontrolsystem.ThispaperhasmadeacomprehensivestudyonthecharacteristicsoftraditionallightingandmodernlightingbycomparingtheadvantagesanddisadvantagesandhasputforwardawirelessintelligentcontrolschemebasedonZigbee,whichusetwopiecesofZigbeefunctionboard:oneworkedasasignalemission,conductingthephotosensitivesensorandpyroelectricinfraredsensor;theotherconnectedtotherelaymodulereceivesthesignalandcontrolsthelights.Underthiskindofcontrolmode,onlywhentheinteriorhaspeoplewithinsufficientlightwillthelightlights.Otherwiseitwon’t.Thiscontrolmethodcanwellsolvetheproblemofopencircuitbymistakeandenergywaste.Thispaperdetailsthefunctionofcontrolsystem,controlstrategyandsoftwaredesignincludingtheLEDlightsinitialization,lightsensorinitialization,PIRsensorinitialization,protocolstackinitializationandserialcommunication,etc..Finally,thispaperteststhefeasibilityandperformanceinasimulatedenvironment.TheresultshowsthatZigbeewirelesscontrolnotonlyhasagoodcontroleffect,butalsosignificantlyimprovetheeffectofenergysavingandimprovetheproblemoflightingupwhilethereisnobody.III目录摘要.........................................................................................................................IAbstract.................................................................................................................II第1章绪论..........................................................................................................11.1基于Zigbee灯光控制系统研究的背景..............................................11.2现有灯光控制方案................................................................................21.2.1传统灯光控制............................................................................21.2.2声控有线自动控制....................................................................21.2.3光强无线灯光控制....................................................................21.3方案比较................................................................................................21.3.1传统灯光控制方式....................................................................21.3.2声控有线自动控制....................................................................31.3.3光强无线灯光控制....................................................................31.4本文设计方案........................................................................................31.4.1Zigbee无线智能控制...............................................................31.4.2Zigbee控制方案优势...............................................................31.4.3Zigbee控制研究意义...............................................................4第2章Zigbee简介.............................................................................................52.1Zigbee介绍...........................................................................................52.2CC2530..................................................................................................52.3基于CC2530实验板..............................................................................62.4光敏传感器............................................................................................82.5热释电红外线传感器............................................................................9第3章Zigbee无线智能灯光控制...................................................................113.1Zigbee无线控制结构.........................................................................113.2设计说明..............................................................................................113.3系统软件的实现..................................................................................133.3.1开发环境介绍..........................................................................133.3.2系统初始化..............................................................................14第4章硬件仿真结果分析................................................................................194.
