摘要随着科学技术的发展和人们生活水平的提高，人们越来越注重自己生活环境的舒适、安全与便利。近年来兴起的智能家居系统满足了人们的这种需求，它有效地在家居环境中组建家庭信息网络，将各种家电产品结合成一个有机整体，对家电设备进行集中或异地的智能化控制与管理，并且能够与外界进行信息交流。蓝牙技术作为一种无线数据与语音通信的开放性全球规范，可提供低功耗、短距离的无线空中接口，在各种固定与移动设备之间实现无线通信。在移动通信、无线数据采集、无线遥控与遥测、计算机网络及自动控制等多种领域，蓝牙技术都有着广泛的应用。应用设计的蓝牙软硬件接口，本文开发了一个基于蓝牙模块的智能家居控制系统，在该系统中，上位机端通过USB控制蓝牙适配器，其发送的控制指令由下位机端蓝牙模块接收后传给单片机，并在单片机端编写了一个基本的蓝牙及模拟家电控制程序，从而实现了PC与模拟家电的无线控制功能。本文提供的蓝牙软硬件接口方案及数据传输模块，不仅可以用来进一步开发蓝牙高层协议，而且还可作为通用的接口函数和模块应用到多种无线场合。关键字：蓝牙技术；智能家居；蓝牙模块ABSTRACTWiththedevelopmentofscienceandtechnology,andtheimprovementofpeople’slivingstandards,peoplearepayingmoreandmoreattentiontothecomfortablity,safetyandconvenienceoftheirlivingenvironment.Theemergenceofsmarthomesysteminrecentyears,justmeetstheneedsofpeople.Iteffectivelyconstitutesappliancesintoahomeinformationnetworkandmakesallkindsofappliancescombinedintoanorganicwhole.Itcanintelligentlycontrolapplianceslocallyorremotely,andexchangeinformationwiththeoutsideworld.AsagloballyopenwirelessdataandspeechcommunicationspecificationBluetoo—thtechnologycanprovidelow-power、shortdistancewirelessairinterfaceandimplementwirelesscommunicationbetweenvariousfixedandmobileequipments．Bluetoothtechnologyhasawiderangeofapplicationsinmobilecommunications，wirelessdatacollections，wirelessremotecontrolandsensingComputernetworkandautomaticcontrolandotherareas．Usingthebluetoothhardwareandsoftwareinterfacedesigned，ThispaperdevelopedansmarthomefurnishingcontrolsystembasedonBluetoothmodule．Inthesystem，ThePCsideiscontrolledbyUSBbluetoothadapter．It’scontrolinstructionisreceivedbythelowerendofBluetoothmodulewhichsentittothemicrocontroller.AbasicbluetoothandhomeappliancecontrolsimulationprogramwaspreparedintheMCU.So,thesystemcanrealizewirelesscontrolfunctionofPCandsimulationofelectricalappliances.Andthen，datacanbetransmittedbetweenthetwoparts．Afterthat，afurtherdevelopmentwhichisfiletransmissionisimplemented．Keywords:Bluetoothtechnology;smarthome;Bluetoothmoudule目录前言.....................................................................1第一章绪论............................................................21.1课题研究背景.......................................................21.2智能家居的发展状况.................................................21.3未来智能家居的发展趋势.............................................31.4研究的目的和意义...................................................31.5课题研究的内容.....................................................4第二章蓝牙技术介绍.......................................................52.1蓝牙系统组成.......................................................52.2蓝牙协议栈.........................................................62.3蓝牙控制器接口(HCI)分析............................................62.3.1HCI概述......................................................62.3.2HCI传输层....................................................72....
