technical approach
Technical Approach
  • Integrated RFID and GPS vehicle monitoring unit
  • Designed for Universities and Dealerships.
  • Priced at $7000
  • Projected budget on track
device layout

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

effects of problems on cost
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
future tasks and schedule
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

Problems addressed:

  • Serial vs USB GPS system
  • Active vs Passive RFID
  • Individual power vs Single power supply
  • Handheld vs Vehicle mounted unit
