摘要随着人们生活水平的提高，居民住宅内的各类用电器越来越多，室内供电线路也越来越复杂。学生宿舍中许多同学无视学校纪律，使用电水壶、电热锅等大功率违禁电器。这些现象在给人们带来便利的同时，也产生了很多安全隐患，比如电气火灾、人身触电等。室内用电安全隐患和环境安全隐患对人们的生命和财产安全造成了极大的威肋，也会给社会带来难以估计的经济损失。因此，室内用电保护监测和诊断成为人们普遍关注的话题。目前室内用电安全保护装置多为低压断路器，即人们常说的空气开关，当线路电流过载时就会自动断开，这种设备功能比较单一，对许多不容易被发现的用电隐患无能为力。本文从全新的角度出发，依托传感器技术、计算机网络技术、嵌入式技术等物联网相关技术，设计了室内用电安全监测面向大数据应用的室内安全监测智能系统。采用了基于电流波形采集与分析的负载电力特征参数提取算法，除了可以监测短路、过载等即时性安全隐患外，借助目前迅速发展的云计算处理方法，还可以对家庭电路进行持续性状态分析，旨在解决不容易被常规电路保护装置发现的潜在危险，为每个家庭提供一种室内供电线路电流提取、分析计算的安全监控装置。本课题对于提升普通住宅、学生宿舍、酒店宾馆等场所的安全监控效果具有重要意义，另一方面，也是将物联网技术和大数据处理方法运用于居民用电安全监测诊断领域的一次全新探索。关键词：用电安全；云计算；电路分析；智能监控诊断系统AbstractWiththeimprovementofpeople'slivingstandards,therearemoreandmoretypesofelectricalappliancesinresidentialhouses,andindoorpowersupplylinesarebecomingmoreandmorecomplex.Manystudentsinthedormitorydonotregardschooldisciplineanduseelectrickettles,electriccookersandotherhigh-poweredcontrabandappliances.Whilethesephenomenahavebroughtconveniencetopeople,theyhavealsocreatedanumberofsecurityrisks,suchaselectricalfiresandelectricshocks.Indoorelectricitysafetyhazardsandhiddendangerstotheenvironmenthavecausedgreatthreatstopeople'slivesandpropertysafety,andtheyhavealsobroughtincalculableeconomiclossestothesociety.Therefore,monitoringanddiagnosisofindoorelectricityprotectionhasbecomeatopicofcommonconcern.Atpresent,indoorpowersafetyprotectiondevicesaremostlylow-voltagecircuitbreakers,whicharecommonlyreferredtoasairswitches.Whenthelinecurrentisoverloaded,theywillbeautomaticallydisconnected.Thistypeofdevicehasarelativelysinglefunctionandisincapableofpowerfailuresthatarenoteasilydetected..Thisarticlefromanewperspective,relyingonsensortechnology,computernetworktechnology,embeddedtechnologyandotherthingsrelatedtotheInternetofThings,designedindoorelectricitysecuritymonitoringforlargedataapplicationsforindoorsecuritymonitoringintelligentsystem.Theloadpowercharacteristicparameterextractionalgorithmbasedoncurrentwaveformacquisitionandanalysisisadopted.Inadditiontotheabilitytomonitorshort-term,overload,andotherreal-timesecurityrisks,withthecurrentrapiddevelopmentofcloudcomputingprocessingmethods,itisalsopossibletoperformcontinuousstatusanalysisonhomecircuits.Designedtosolvepotentialhazardsthatarenoteasilydetectedbyconventionalcircuitprotectiondevices,eachhomeisprovidedwithasafetymonitoringdeviceforcurrentextraction,analysisandcalculationoftheindoorpowersupplyline.Thistopicisofgreatsignificanceforimprovingthesafetymonitoringeffectofordinaryhouses,studentdormitories,hotelsandotherplaces.Ontheotherhand,itisalsoanewexplorationofapplyingtheInternetofThingstechnologyandbigdataprocessingmethodstothefieldofresidentialelectricitysafetymonitoringanddiagnosis.Keywords:electricitysafety;cloudcomputing;circuitanalysis;intelligentmonitoringanddia...
