Using RFID Technology

IntroductionRFID vehicle access control system with high

identification accuracy, designed to track and

manage vehicles in parking areas or gatedcommunities to allow for accurate vehicletracking as well as easy in-and-out access

fordrivers.

What is RFID?RFID:A technology that uses radio frequency

waves to transfer data between a reader and movable

item for detection,tracking or identification purpose.

RFID is also called Dedicated Short Range

Communication or DSRC.

Components An antenna or coil.

A transponder (RF TAG) electrically programmed

with unique information.

An antenna and transceiver are together called

as an

interrogator or reader.

Host computer and appropriate software.

We can have RNC’s (reader network controller).

Sequence of operation

1. Carrier signals sent by the reader (upon request

from the host application).

2. Carrier signal hits tag(s).

3. Tag receives and modifies carrier signal:

• “sends back” modulated signal.

4. Reader receives & decodes the data.

5. Results sent to the host application for further

processing.

RFID OperationTag

Operation in AVI

RFID readers Reader sends out a wave to the tag which

broadcasts back its stored data to the reader.

The data collected from the tag is uploaded on the computer.

Readers can be: Fixed Hand-held Wireless

Long Range Readers

Long Range readers have high speeddetection technique.The readers can bemounted directly onto metal surfaces

making it ideal for vehicle identification.The stylishdesign makes this reader an eye-catcher forevery entrance.

Long Range Readers

Key Features: Range up to 10metres Speed up to 200kmph Weatherproof Protected Housing Multi-channel frequency offset Highly controlled detection zone

RFID Frequencies

RFID systems are classified on the basis of frequency used: Low Frequency(30-300KHz) High Frequency(3-30MHz) Ultra High Frequency(300MHz-2GHz) Microwave(2-30GHz)

Within a frequency band the actual range will vary

widely because of factors like operating environment,

antenna design,available system power.

Frequency in AVI

AVI technology works at the 2.45GHz frequency band.

Typical qualities are: Highly directional Dense reading area eliminates 'black spots' ID-tags can be read at high speed No need for site license Easy installation

2.45GHz Frequency

Technical features: Frequency hopping(FHSS) IP 65 enclosure SQL database support Flexible Supply Voltage(10-30V DC) CE and FCC approved

RFID TagsIn an RFID system the transponder that contains the

data to be transmitted is called an RF tag.It is the core

of the RF-ID System. Different types of RF tags are:

Active Semi-passive Passive

Mainly Active tags are used

for Vehicle Identification purposes.

Active Tags Key Features:

Communicate via Industry Standard Protocol

IEEE 802.15.4• CSMA for Anti-Collision• Maximum data rate:250Kbps

Operating Voltage: 2-5V Operating Temperature: -10C to 80C Shock and Vibration Resistant 12-bit sensor precision

Active Tags Technical Features:

Active tags have Integrated Antenna • Saves size and cost• Can be read in almost every orientation

Tag Frequency: 2.45GHz Solder Contacts for connecting an externalcontact sensor Wake-up Sensor

• Magnetic Reed Switch• Vibration sensor

Types of Tags

TAGS

Vehicle Based Tags

Driver Based Tags

Vehicle Based Tags

The vehicle based tags are mounted to either

in the windshield of the vehicle or on theexterior of the vehicle itself in order to

identifyit over long range without the need to come to stop.

Types of Tags

Vehicle Based Tags

Compact Tag

Window Button

Window Button Switch

Heavy Duty Tag

Driver Based Tags

Driver Based Tags offer fast and secure vehicle

access for authorized drivers.This ensures that a vehicle

can never get access to a secured area unless occupied

by an authorized Driver.It is made up of: Booster Personnel access Badge

Electronic Product Code

Objective: To provide unique identification of physical

objects. It is of total 95 bits.

Header

0-7 bits

ECP Manag

er8-35 bits

Object Class36-59 bits

Serial Number60-95 bits

EPC Network Architecture

Savant: Middleware software system that links reader

devices and processes the information streams from tags.

Object Naming Service(ONS): It is the glue that links the EPC™ with the

associated data file. ONS system is built on the same technology

used in the Internet’s Domain Name Service(DNS).

Provides a look-up table for translating an unique EPC code into a Uniform Reference Locator.

AdvantagesLong-range identification system facilitates true

hands-free vehicle identification.The system is designed to provide:+ Convenience+ Revenue Enhancement+ Efficiency Improvement+ Automatic Data Collection+ Highly Secure Vehicle Access

Applications Toll Application

Parking Management

Enroute-Vehicle Identification

Traffic Control

Theft Protection
