Project PBoT Zone Surveillance

1. Project PBoT Zone Surveillance • Advisor • Dr. Joseph Hoffbeck • Industry Representative • Mr. John Turner • Impinj, Inc. Team Steve Beyer Carolyn Farris Emily McKaig University of Portland School of Engineering

2. Agenda • Introduction Emily McKaig • Background Emily McKaig • Methods Carolyn Farris • Results Carolyn Farris & Steve Beyer • Conclusions Steve Beyer • Demonstration Team Wire Lettuce University of Portland School of Engineering

3. Introduction • The Team: • Steven Beyer (Fall Lead) • Carolyn Farris • Emily McKaig (Spring Lead) • Our Supporters: • Dr. Joseph Hoffbeck (Adviser) • Dr. Tanya Crenshaw • Mr. John Turner (Industry Representative) • Mr. Keith Ehrensing (Portland Bureau of Transportation) • Mr. Charles Mooney University of Portland School of Engineering

4. Background Current System at the Portland Bureau of Transportation (PBoT): • Antiquated (VHS Tapes) • Installation is difficult (weighs over 70 lbs) • Requires frequent maintenance (lasts only 3 days between visits) University of Portland School of Engineering

5. Objectives Improve the current system: • Solar power • Wirelessly transmit the video feed to PBoT • Smaller, lighter components University of Portland School of Engineering

6. Methods • Design in the Fall • Implementation in the Spring • Scheduled Milestones University of Portland School of Engineering

7. Methods: Fall • Project Proposal • Met with Client • Functional Specification • Researched Components • Design Document University of Portland School of Engineering

8. Methods: Spring • Ordered Components • Interfaced Network Device and Camera to Gumstix • Power Testing • Ordered Encasement • Client Demonstration University of Portland School of Engineering

9. Results: System Architecture University of Portland School of Engineering

10. Results: Power • Interfaced existing PBoT circuits to power the gumstix and camera • Solar panel charges the battery University of Portland School of Engineering

11. Results: Camera • LinkSprite JPEG Color Camera TTL Interface • Preset commands to take a picture and receive it • Can set picture size and control how often a picture is taken to optimize for client needs University of Portland School of Engineering

12. Results: Gumstix Processor • “Brain” of the device • Coordinates the receiving of the picture from the camera with sending the picture over the network University of Portland School of Engineering

13. Results: Gumstix Software University of Portland School of Engineering

14. Results: Storage on Base Unit • The base unit is any computer with an internet connection • All pictures are stored in a directory specified by the user • For the client, this will be a machine at the PBoT Headquarters University of Portland School of Engineering

15. Conclusions We have greatly improved the device: • The user can access the video feed at a remote location, as the pictures are sent • Device is much lighter Other improvements for future development • Smaller, lighter battery • Optimize software for more frames per minute University of Portland School of Engineering
