Design of a low cost embedded system for a parking management in a smart city

Abstract

Modern smart city is facing numerous technological as well as administrative challenges in many frontsinvolving man and machines. One of these is the smart transportation system aided with cutting edgepublictransitmodeslikebus,monorail,metroandsoonsoforth.Howeverneedlesstosayonlyhavinganadequate public transport system will not suffice the need of end to end mode of transport. Hence anefficient and hassle free parking system is inevitable for any modern day smart city. With advancementsof technologies like Internet of Things (IoT) and cloud platforms it is now technologically feasible todesign and deploy systems to incorporate automation in traditional parking systems and hence makingvehicle parking more organized and hassle-free and would require very less human interventions. First Ihave explored the existing parking management system and specifications of the proposed system isprepared. Here Data flow diagram, Use case diagram and different modules of the system is figured out.ThensoftwarehasdevelopedtomanagepaymentsandissueNFCcard.Arduinoisusedforthedevelopmentoffrontendandgooglesheetusedforbackend.Thenhardwarecircuitoftheproposedsystemdesigned using the EDA software Proteus.
