摘要煤气已成为人们生活中必不可少能源了,煤气泄漏时有发生,煤气泄漏使人中毒,也许会发生爆炸,给人们人身安全和财产安全带来了诸多隐患,因此防止煤气泄漏检测装置已成为人们迫切需要,为此开发煤气泄漏报警检测装置是非常必要。计算机以及单片机普及和信息技术迅猛发展,人们已经对家庭住宅环境提出了更高规定,智能化、信息化被引入家庭,便利,舒服并且更加安全。家庭智能化定义,在国际上至今尚无一致理念,在当代化城乡住宅社区中和采用微型计算机、自控装置、通信等技术,建立一种物业管理中心与安全防护监控系统,最后目是使每一种祝贺得到满足其规定最佳方案。这些足以表白人们最注重还是安全。并且国家建设部规定,当前住宅社区应实现六项智能化规定,其中就涉及实行安全防范系统自动化监控管理;防盗报警系统应安红外或微波与煤气泄漏报警器等各种类型报警装置,基于此项规定,煤气泄漏检测报警装置实现智能化势在必行。本系统重要针对老式煤气,液化气泄漏进行检测,报警。本系统有如下特点:用单片机实现控制,电路简朴、价格便宜、可靠性好。采用增强型51单片机,MQ-2气体传感器,煤气泄漏是会发出灯光和声音报警,因而本系统可作为智能家居一种安全系统!核心词:煤气泄漏;单片机;气体传感器AbstractGashasbecomeanessentialenergyinpeople'slives,Gasleakincidentoccasionally,gasleakcanmakepeopleexplode,broughtalotofhiddendangerstopersonalsafetyandpropertysecurityofpeople,sotopreventthegasleakdetectionthedevicehasbecomeanurgentneed,forthedevelopmentofthegasleakalarmdetectiondevicesisnecessary.Thepopularityofcomputerandmicrocontroller,andtherapiddevelopmentofIT,peoplehavebeenraisedonthefamilyresidentialenvironmentahigherdemandintelligence,informationwasintroducedtothefamily,convenient,comfortableandmoresecure.Thedefinitionofthefamilyofintelligent,intheinternationalcommunitysofarthereisnoconsistentphilosophyinthemodernurbanandruralresidentialareaandtheuseofmicro-computer,automaticcontroldevices,communicationtechnologiessuchastheestablishmentofapropertymanagementcenterandthesecuritymonitoringsystem,theultimateaimiseachcongratulategetthebestsolutiontomeettheirrequirements.Thesearesufficienttoshowthatthesecurityfocus.TheprovisionsoftheMinistryofConstruction,theresidentialareashouldachievesixintelligent,includingtheimplementationoftheautomatedmonitoringandmanagementofsecuritysystem;burglaralarmsystemshouldbeinfraredormicrowave,gasleakalarms,andothertypesofalarmdevices,basedonthisparagraph,gasleakdetectionalarmdeviceintelligenceisimperative.Thissystemismainlyforconventionalgas,liquefiedpetroleumgasleakdetection,alarm.Thissystemhasthefollowingcharacteristics:withMCUcontrolcircuitissimple,cheap,andgoodreliability.Enhanced51microcontroller,theMQ-2gassensors,
