PDR Presentation: October 25th, 2007
Technical Approach Integrated RFID and GPS vehicle
monitoring unit
Designed for Universities and Dealerships.
Priced at $7000
Projected budget on track
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

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
GPS Unit
Pharos iGPS-500 WAAS capable GPS
unit Better than 3 meter
accuracy Unit outputs TTL

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 1,247Labor 12,083Total $25,344
Development Cost (Non-recurring Cost) with Additional $100 for GPS
unit Parts 1,347Labor 13,483Total $28,211
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
Summary
Problems addressed:
• Serial vs USB GPS system
• Active vs Passive RFID
• Individual power vs Single power supply
• Handheld vs Vehicle mounted unit
