INTERFACING MICRO-CONTROLLER AND RFID TOWARDS A SECURE EMBEDDED CAR PARKING MODEL

Abstract

This research focused on an integrated car parking solution that guides drivers on the exact parking lots at a specified period of time. In addition, it is a simplified monitoring and intelligence gathering of parking occupancy. It is based on the Radio frequency identification (RFID), micro controller and sensors which guide entry and outgoing of the vehicles. In this technique the RFID card is swiped, with the permission of vehicle’s parking owner. Using the Half Bridge concept, DC motors were used for the operation of entry and exit boom. The DC motors operate clock wise and antilock wise as per the program. When the vehicles enter the parking space, the space available in the parking system reduce and vice versa. It operated on a standard power supply of 5 volt and a LCD display showing all the activities. The microcontroller was interfaced to a car parking software with hashed database encryption and an RFID card authenticator recording incoming and outgoing vehicles in real-time. The use of cameras, RFID tags, readers and antennas made it easier to automate the 'in and out' privileges of parking subscribers.
