基于GPRS网络的取水远程实时监测系统设计与实现 Abstract: Waterisanessentialresourceforalllivingbeingsanditsmanagementiscrucialforsustainability.Inrecentyears,theadventofremotemonitoringtechnologieshaveenabledreal-timemonitoringofwaterresourceswhichcanprovideefficient,reliableandtimelyinformationforwaterresourcemanagement.Inthispaper,weproposearemotewatermonitoringsystemthatisbasedonGeneralPacketRadioService(GPRS)networkwhichenablesreal-timemonitoringofwaterusage,andprovidesaconvenientandefficientmethodforwaterresourcemanagement.Theproposedsystemisdesignedforremotemonitoringofwaterusageinagriculturalandindustrialsectors. Introduction: Waterconservationhasbecomeamajorconcernworldwide,especiallyinregionswherewaterresourcesarescarce.Monitoringwaterusageinreal-timecanhelpinefficientmanagementandconservationofthispreciousresource.TheproposedsystemusesGPRStechnology,whichenablesremotemonitoringofwaterusageinreal-time.TheGPRSnetworkisastandardforwirelesscommunicationonmobiledevicesandcanprovideefficientdatatransferoverlongdistances.
