  7. 7. 7 RFID Tag  The RFID tag houses a unique identification code, typically 64 bits in length.  A secure, unique identification code is transmitted to a reader/antenna upon activation of the tag by an appropriate radio frequency signal.  RFID tags contains two parts.  Integrated circuit for storing and processing the data.  Antenna for receiving and transmitting the signal.  These tags can operate on many levels of frequency ranging from 125 KHz until 915 MHz. 11/19/2013
  8. 8. 8 RFID Reader  A device used to communicate with RFID Tag.  The reader has one or more antennas , which emits radio waves and receive signals back , from the RFID Tag.  Also called Interrogator because it interrogates the RFID Tag.  Data retrieval - RFID Reader – Device - Emits radio waves - Received by the RFID Tag - Activates the microchip - data get transmitted. 11/19/2013
  9. 9. 9 GSM  GSM ( Global system for mobile communication ).  Globally accepted standard for digital cellular communication.  GSM is a common European mobile telephone standard for a mobile cellular radio system operating at 900 MHz.  In the current work, SIM300 GSM module is used.  It delivers voice, data and fax in a small form factor with low power consumption. 11/19/2013
  10. 10. 10 Vehicle Tracking . . . How it works ?  One RFID is placed in vehicle with owner info, RC book, insurance details, service details etc. to send vehicle identification to traffic information database.  RFID reader will be placed with embedded controller in Secure access points , Toll Gates, Parking areas and also in traffic signal areas.  We used GSM module with embedded unit in the moving vehicle to transmit accident information to different points. 11/19/2013
  11. 11. 11 How it works ? ( Continued . . )  Whenever vehicle meets with an accident, the system reads area information from RFID Readers/Tags placed on the road and transfers this information to embedded module.  The details are transmitted to the specific numbers stored in database (Police station, Owner and Hospital).  Whenever the vehicle crosses the particular road area, the data from Vehicle tag is read and based on the location, an SMS regarding location of the vehicle will be sent to the owner. 11/19/2013
  12. 12. 12 RFID Tag types  Passive Tags  No internal power supply;  Microchip is in sleep mode, until the tag is in the range of the reader,  Reader sends electromagnetic waves - wake up the microchip  converts the waves into digital data using modulators and send it to the reader. 11/19/2013
  13. 13. 13 RFID Tag types ( Continued . . . )  Active Tags  Own internal power supply  Used to power the integrated circuits and to transmit the data to the reader.  Communication with readers is typically much more reliable.  Can have on- board electronics such as sensors, I/O ports  The read range of the tag can reach 100 meters. 11/19/2013
  14. 14. 14 RFID Tag types ( Continued . . . )  Semi-Passive Tags  Lay between the passive and the active tags  Because they have a battery to power the integrated circuit  However they use the power from the electromagnetic waves that the reader sends in order to retrieve the data present on the tag. 11/19/2013
  15. 15. 15 RFID Tag Types ( Mode of Operation )  The tags can be distinguished by their mode of operation as follows:  Read Only Tags .  Read/Write Tags  WORM Tags 11/19/2013
  16. 16. 16 Design and Implementation  The current design has following 3 operating points.  Road unit  Vehicle unit  Alert receiver unit. 11/19/2013

  18. 18. 18 On Road Unit  ‘N’ number of RFID tags to transmit general area information and alert on special zones like school, hospital, weak bridges and zigzag bends etc.  UHF Semi passive tag is used in our application.  Its coverage is a maximum of 50 Meters.  The location information and driver alert information are stored in this tag. 11/19/2013
  19. 19. 19 Vehicle Unit  These units consist of RFID reader, vehicle information RFID Tag, 8051 embedded module and GSM module.  Here we have used SIM 300 GSM module to transmit alert data to the mobile receivers already configured.  RFID reader and GSM are connected to receive and transmit of the serial port in embedded module. 11/19/2013
  20. 20. 20 Alert Receiver Unit  This unit is nothing but alert receiving mobile phones programmed in the embedded module.  It may be owner of the vehicle, the hospital emergency care and the police station information number.  Short script message or voice message will be sent to the receivers. 11/19/2013
  21. 21. 21 Implementation  Let's go to RFID System to understand better  Special zones like School, Hospital, Zig Zag bends and weak bridge etc., are programmed in the RFID tag.  Whenever vehicles crossing that area, embedded module will alert the driver to reduce acceleration. This will control accident ratio. 11/19/2013
  22. 22. 22 Implementation ( Contd . . )  RFID Tag is placed inside vehicle to transmit vehicle information.  In the traffic signal management system RFID reader and display informer unit are connected with serial port of the microcontroller.  If vehicle insurance, pollution test, FC is not proper, the alert system will produce beep sound and vehicle number is displayed.  Then the traffic police can easily alert the driver / owner. 11/19/2013
  23. 23. 23 Implementation Scenario  CHALLENGE  Municipality of Pendik in Istanbul, Turkey, operates a highly trafficked parking area - owned fleet of1,000 vehicles.  The lot has four gates, far away from each other.  The municipality did not want to hire four parking lot attendants.  Use RFID to efficiently track vehicles going in and out of a parking lot. 11/19/2013
  24. 24. 24 Implementation Scenario ( Contd ..)  SOLUTION  Municipality of Pendik worked with STS technology, a Turkish RFID solutions firm, to develop vehicle tracking solution.  Each vehicle has an Alien M tag, which is applied inside the windshield.  On gates, STS deploys Alien reader for the entrance and exit to monitor the parking lot traffic.  Each reader can detect the vehicle tags from approximately five to six meters. 11/19/2013
  25. 25. 25 Implementation Scenario ( Contd ..)  RESULTS  STS’s RFID solution for the municipality was able to overcome the challenges of monitoring the fleet.  Collect the data automatically and without/reduced human action.  The municipality gets reports from its IT system, and it can easily track the employee’s vehicles and parking lot status.  Drivers are not busy opening the gates — they are only driving their vehicles. 11/19/2013
