  • 1. RFID Vehicle Tracking
    • Jason Alcock (Team Leader)
    • Pat Woowong
    • Harold Allen
    • Emmanuel Deheer
    • Farzaneh Shahheidari
    • Project Advisors:
    • Jay Schlag
    • Linda Milor
    • PDR Presentation: October 25 th , 2007
  • 2. Technical Approach
    • Integrated RFID and GPS vehicle monitoring unit
    • Designed for Universities and Dealerships.
    • Priced at $7000
    • Projected budget on track
  • 3. Device Layout
    • RFID Reader
      • Serial interface
      • Only active RFID tags read
      • Receives incoming tag information
    • GPS Unit
      • Serial Interface
      • Longitude/Latitude coordinates updated when unit moves
    • Display
      • USB Interface
      • Two-way communication between user and Ebox
    • Ebox PC
      • USB, Serial, VGA
      • 10/100 Ethernet for data download
      • Flash memory storage contains operating system and database
    EBOX Display RFID Reader GPS Unit Serial Serial USB
  • 4. Basic Software Flowchart Pair current GPS location with tag info Search database for valid information Display relevant tag information of oldest vehicle on linked list Wait for incoming tag data Store paired data in a linked list Valid? Yes No Mark Tag for Violation
  • 5. Embedded Processor
    • ICOP eBox-2300
    • Vortex86 200MHz System-on-Chip
    • 3x USB v1.1ports
    • 2x RS-232 serial ports
    • Windows CE OS

  • 6. RFID Reader
    • R500-SP long range RFID reader
    • Proprietary RS-232 serial interface
    • Active RFID tags
    • Typical 20-30 foot range
    Source: www.RFIDusa.com
  • 7. RFID Serial Interface
    • Proprietary undocumented Serial interface
    • Connected to PC and logged serial data
    • Used included demo program to sniff byte pattern
    • Concluded important byte data for implementation
  • 8. GPS Unit
    • Pharos iGPS-500
    • WAAS capable GPS unit
    • Better than 3 meter accuracy
    • Unit outputs TTL level serial output
    • Must create cable to interface with RS-232 connection

  • 9. LCD Interface
    • Matrix Orbital GLK19264-7T-1U-USB-GW
    • Serial graphic LCD with seven buttons
    • Virtual serial port over USB connection

  • 10. Prototype Demonstration Base Unit Target Vehicle Ebox LCD Panel RFID Reader GPS Unit RFID Tag Affixed to Vehicle
  • 11. Successful Testing VIN: J3425HK5896 Location: EW 96 Match? No! Ticket! 20 foot radius Transmitted signals from RFID tag. Mobile Base Unit LCD Display
  • 12. Effects of Problems on Cost
    • Wrong GPS unit was not compatible with e-Box
    • Additional GPS unit increased the overall development cost of project by increasing:
      • Part cost
      • Labor cost
    Previously Calculated Development Cost (Non-recurring Cost) Parts 1,247 Labor 12,083 Total $25,344 Development Cost (Non-recurring Cost) with Additional $100 for GPS unit Parts 1,347 Labor 13,483 Total $28,211
  • 13. Future Tasks and Schedule
    • 11/8 - Compilation of a working RFID program for the e-Box controller
    • 11/12 - Development of software program to parse a text document containing RFID tag information
    • 11/12 - Development of code to interface the LCD display
    • 11/18 - Assembly of base unit
    • 11/18 - Inclusion of appropriate power supply system into base unit
  • 14. Summary
    • Problems addressed:
    • Serial vs USB GPS system
    • Active vs Passive RFID
    • Individual power vs Single power supply
    • Handheld vs Vehicle mounted unit
  • 15. “ It is always appropriate to end a presentation with a quote to allow the audience to digest everything before a question and answer period” -Michael Laughter October 2007
