内蒙古科技大学本科生毕业设计说明书（毕业论文）题目：基于PLC的智能家居安防系统学生姓名：许剑学号：200540501330专业：自动化班级：自2005-3班指导教师：任彦讲师内蒙古科技大学毕业设计说明书（毕业论文）I基于PLC的智能家居安防系统摘要随着我国经济的快速发展，生活水平的不断提高，人们对居家的概念已从最初满足简单的居住功能发展到注重对住宅的人性化需求。安全、舒适、快捷、方便的智能小区，已成为住宅发展的主流趋势，其中，安全性是首要目标。智能小区安全性的实现，除了人为的因素外，主要依靠小区的智能化安全防范系统。所以研究和开发智能家居安防系统具有很高的实用价值。在安防系统中，防火和防盗是主要的。因此，通过传感器把各种防火防盗的信号传输给小区报警中心，小区报警中心能迅速做出反应，阻止不法分子的得逞和火灾的发生。智能安防系统就是保障了人们居家的安全和利益，使人们的生活更加安全、舒适。所以设计和开发智能家居安防系统，不仅具有很强的现实意义，也有广泛的市场前景。本设计介绍了西门子S7-300的通信协议和工控组态软件WinCC在家具安防系统中的应用,并讨论通过用MPI网络实现S7-300与工控组态软件WinCC之间通信和用PROFIBUS-DP总线实现S7-300与S7-300之间通信的方法。关键字:智能小区；安防系统；WinCC；住宅；报警内蒙古科技大学毕业设计说明书（毕业论文）IIBasedonPLCintelligenthouseholdsecuritysystemAbstractWitheconomyrapiddevelopedandlivingstandardcontinuousimproved,people’sconceptofhomehaschangedfrominitialsimplelivingfunctiontotheindividualdemands.Theintelligentcommunity,whichissafe,convenientandcomfortable,hasbecomethehousingdevelopmenttendency.Andsafetyistheprimarytargetinthattendency.Thesafeoftheintelligentcommunity,exceptforhumanfactors,mainlyrelyonsafeguardsystemofintelligentcommunity.Sotheresearchanddevelopmentofintelligenthouseholdsecuritysystemhashighpracticalvalue.Inthesecuritysystem,fireproofingandsecuritysystemisveryimportant.Therefore,iftransmitvariousfire-theftalarmsignaltothecommunityalarmcentersthroughthesensor,communityalarmcenterscanrapidreactionsothatpreventthelawbreakers’actionsandpreventfireoccurrence.Intelligentsurveillancesystemistheguaranteeforthesecurityandinterestsofthehousingpeopleandmakesthelifeofpeoplemoresafeandcomfortable.Sothedesignanddevelopmentofintelligenthouseholdsecuritysystem,notonlyhasastrongpracticalsignificance,buralsohaswideprospectofmarket.ThisdesignintroducesapplicationofSiemensS7-300communicationprotocolandtheindustrialcontrolconfigurationsoftwaresecuritysystemWinCCinfurnituresecuritysystem.ThenthepaperdiscussesthemethodswhichuseMPInetworktorealizethecommunicatingbetweenS7-300andindustrialcontrolconfigurationsoftwareWinCC,andusePROFIBUS-DPtorealizethecommunicatingbetweenS7-300andS7-300.Kyewords:Intelligentvillage;Securitysystems;WinCC;House;alarm内蒙古科技大学毕业设计说明书（毕业论文）III目录摘要.............................................................................................................................................IAbstract......................................................................................................................................II第一章概述..............................................................................................................................11.1绪论.............................................................................................................................11.2PLC的应用领域和发展趋势.....................................................................................21.2.1PLC的应用领域................................................................................................21.2.2PLC的发展趋势................................................................................................31.3西门子S7-300简介...................................................................................................41.3.1一般特性............................................................................................................41.3.2模块的种类........................................................................................................41.3.3通信....................................................................................................................51.3.4扩展功能............................................................................................................61.4监控软件WinCC简介...............................................................................................61.5STEP7编程软件简介................................................................................................71.6智能家居安防系统开发的必要性.............................................................................81.7国内外发展现状.........................................................................................................81.8论文的主要研究内容.................................................................................................8本章小结.............................................................................................................................9第二章智能家居安防系统....................................................................................................102.1智能家居安防系统的组成与工作原理...................................................................102.1.1智能家居安防系统的组成..............................................................................102.1.2智能家居安防系统的工作原理......................................................................112.2智能家居安防系统的设计.......................................................................................112.2.1系统的硬件设计..............................................................................................112.2.1.1S7-300系列的PLC硬件系统.............................................................112.2.1.2PLC的选型................................................................................
