基于ZigBee技术的桥梁挠度无线监测系统的设计与应用 Abstract Bridgeisoneofthemostimportantinfrastructuresinthetransportationsystem.However,thestructureofthebridgeissubjecttovariousenvironmentaleffects,leadingtotheincreasingriskofbridgecollapse.Therefore,effectivemonitoringofthebridgestructureiscrucialtoensuresafeandreliableoperations.TheZigBee-basedwirelessmonitoringsystemforbridgedeflectionproposesasolutiontothisproblem.ThispaperaimstodiscussthedesignoftheZigBee-basedwirelessmonitoringsystemanditsapplicationinmonitoringthedeflectionofbridges. Introduction Bridgedeflectionmonitoringisessentialforidentifyingstructuraldamageandensuringthesafetyofthebridge.Thetraditionalmonitoringmethods,suchasmanualinspectionandwiredsensors,havetheirlimitationsintermsofcost,timeandsafety.Therefore,wirelesssensornetworks(WSNs)haveattractedincreasingattentionduetotheirhighaccuracy,real-timemonitoring,andlowcost.AmongtheWSNs,ZigBeewirelesssensornetworkshavebeenwidelyusedduetotheirlowpowerconsumption,lowcost,andeaseofdeployment.
