基于物联网的火灾监控系统设计摘要随着通信技术的发展和人们生活水平的提高，安防监控系统逐渐进入大众的视线并成为热门的研究课题。作为安防系统的子系统，家庭火灾监控系统在减少家庭灾害发生，提高人们生活质量方面发挥了重要的作用。传统的家庭火灾监控系统往往存在不嫌不便、单传感器监测准确度不高、远程监控能力不强等诸多缺陷。网络化的火灾监控系统在系统造价上价格不菲，减少监控系统成本和功耗，提高系统集成度和准确度是本课题设计目的。为此，本文提出了一种基于物联网的嵌入式家庭火灾监控系统。运用ZigBee技术构建家庭监控网络的传输链路，依托物联网基础网络设施Internet，实现远程家庭火灾监控。设计多传感器监测环境状态，并将监测数据在智能网关中心进行融合解决，提高监测准确度，得到最终的监测结果；以嵌入式路由芯片RT3052实现智能网关，减少系统的成本和功耗。为了实现该系统，分别对无线传感器网络和智能网关部分进行了具体的硬件和软件设计。为家庭火灾监测设计烟雾、气体、火焰、温度等传感器电路；为入侵监测设计了红外热释电传感电路。以ZigBee单芯片CC2530为核心，构建家庭内部网络通信平台，运用ZigBee2023协议栈实现了无线网络数据通信。通过测试，设计的无线ZigBee网络网关平台能完毕和ZigBee和Internet的交互，能对的采集多传感器数据，监控火情，较高概率对火灾进行监测与报警，达成了预期的目的。关键词：火灾监控；ZigBee；多传感器；智能网关；数据融合ABSTRACTWiththedevelopmentofcommunicationstechnologyandtheimprovementofpeople'slivingstandards,securitymonitoringsystemisgraduallyknownbyusandhasbecomeahotresearchtopic.Asasubsystemofthesecuritymonitoringsystem,homefiremonitoringsystemplaysanimportantroleinreducingfamilydisasters,improvingthequalityofpeople'sLive.Traditionalhomefiremonitoringsystemhasmanydefects,suchasinconvenientwiring,lowmonitoringaccuracyofsingle-sensorandpoorremotemonitoringcapacity.Thenetworkedfirecontrolsystemonthesystemcostisnotcheap,loweringthecostofmonitoringandcontrolsystemandpowerconsumption,improvethesystemintegrationandaccuracyofthistopicdesigngoal.Tothisend,thispaperproposesaembeddedhomefiremonitoringsystembasedonInternetofthings.UsingZigBeetechnologytobuildfamilymonitoringnetworktransmissionlink,relyingontheInternetinfrastructurenetworkInternet,realizethefamilyfireremotemonitoring.Multiplesensorstomonitorenvironmentalstateisdesigned,andthemonitoringdatafusionprocessinginthecenteroftheintelligentgateway,toimprovemonitoringaccuracy,getthefinalmonitoringresults;RoutingonembeddedchipRT3052intelligentgateway,reducethesystemcostandpowerconsumption.Inordertorealizethesystemofwirelesssensornetworkandintelligentgatewaypartcarriedonthedetaileddesignofhardwareandsoftware.Designedforhomefiremonitoringsmoke,gas,suchasflame,temperaturesensorcircuit;Monitoringfortheinvasionofp
