Design and Implementation of a Digital Parking
Lot Management System
This project aims at implementing a digital vehicle management system using radio
frequency identification (RFID) technology. This project plans to enhance the
utilization of parking space and help user check the availability of the parking space remotely as the
system is connected to the Internet. There are four stages of completing this project. The first stage
consists of embedding the code into a tag and assigning the same to a car. the data is read from the RFID tag to the microcontroller in the second stage. the data is uploaded from
microcontroller to the Ethernet network in the third stage. The final stage is to keep a track of vacancies of the parking
spaces.
Introduction
The RFID kit used in this project includes
RFID windshield tags and RFID readers. The RFID reader is connected to a microcontroller in the
control office where the system is connected to the Internet. When a car with
enabled RFID windshield tag drives up to the gate, the RFID reader will automatically read the
information from tag through the built in antenna. and the read information will be delivered to the
microcontroller where the information will be verified. If the information received matches the
information in the database, the control office will send a command to open the gate of the parking lot. The number of
cars in the parking lot and the number of available spaces will be updated online immediately so that
remote user can get the correct parking information.
Introduction to RFID:
RFID is a technology that incorporates the use of electromagnetic or electrostatic coupling in the radio
frequency portion of the electromagnetic spectrum to uniquely identify an object, animal, or a person. The man components of an RFID system are:
- An RFID tag “ transponder.
The RFID tag is activated when it passes through a radio
frequency field and sends out the programmed response. It has a chip that is
programmed with the information that uniquely identifies the tag.
- An RFID reader “ transceiver.
RFID readers are the electronic components that transmit and/or receive the RF waves used to
communicate with the tags. The primary components of the reader are an antenna, IC board, and
memory.
Design of the system
The four stages in which the project is implemented are:
1)Writing into the tag:In this stage, RFID tag is
embedded with unique identification code and is assigned to a car.
2)Reading from the tag: The information from the tag is read during the car parking.
3)Data feed to the microcontroller: The data from the RFID reader is transferred to the
microcontroller for the actual comparison of data and further processes. RS232 or UART media is used for this.
4)Data transfer to Ethernet: This consists of the transfer of data from the
microcontroller to an Ethernet port for the purposes of displaying information for remote people
regarding the availability of parking spaces.
5)Tracking the count. To properly utilize the parking lot, the number of the cars presented in the
parking lot is tracked using microcontrollers.
- A communication protocol for the information transferred.
Hardware setup
The selected Paramountâ„¢s RFID kit is a plug and play device and it has one RS-232 cable and one USB
cable. The USB connection is used for powering up the RFID reader. The tags are written using Mifare
Read & Write software tool which has options to write the tag information in Hexadecimal as well as in ASCII. The Embedded Ethernet Development Kit can be connected to the Ethernet network using a standard
Ethernet cable or directly to a PC using a crossover cable. For a PC to recognize an embedded system on a network, its IP address and subnet mask need to be configured.
Microcontroller and ethernet : Connect the AB4 Ethernet Development Board to the C8051F120 Microcontroller target board at J24. By making use of ribbon cable connect the USB debug adapter to the C8051F120 target board at the JTAG header. Connect the one end of the USB cable to the available USB port of the PC. Connect the other end of the USB cable into the USB connector of the debug adapter. And then Connect the AC/DC adapter to the C8051F120 target board at P1.
