Transcript

  • 1. Wind and Solar Communications Node
    Daniel Lampie
    David Brenner
  • 2. Location
    Actual Project
  • 3. How it Works
  • 4. Electronics
  • Charge Controller
    Prevents the batteries from over charging
    Once the voltage across the batteries hits a set level (13.7v), power is sent to a set of power resistors until the voltage drops
  • 9. Power Meter
    • Monitors current flow to batteries and sends data to a remote server
  • Power Meter
    • Web Site makes it easy to view power data
    Website
    Server Code
  • 10. Wireless
    • Utilizes Wi-Fi Based Equipment
    • 11. Inexpensive
    • 12. High Performance
    • 13. Uses two Linksys WRT54G Wi-Fi Routers
    • 14. Uses DDWRT Firmware for more flexibility
    • 15. One in AP Mode with 8dBi Panel Antenna
    • 16. One in Repeater Mode with 19dBi Parabolic Antenna
    ¼ Mile Link
  • 17. VOIP
    Enables Free Voice Calling
    Allows the communication node to become a wireless phone booth
    Utilizes Google Voice for free incoming calls
    VOIP Server
    VOIP to Analog
    Phone Adapter
  • 18. Innovative Applications
    Third World Rural Locations
    Extend Internet connectivity from urban areas to rural areas
    Connect villages together
  • 19. Innovative Applications
    National Parks
    Provides up-to-date weather and trail information
    Many parks do not provide reliable cell phone coverage
    Hiking fatalities can be prevented by alerting hikers of potential trail and weather danger
  • 20. Innovative Applications
    Disaster Recovery
    Quickly deployable and inexpensive communications network
    Self sustainable –> no need for diesel generators or any other infrastructure that could have been destroyed
  • 21. Team Work
    Key to Project’s Success
    Dan is very knowledgeable of wireless communications and networking
    Dave is knowledgeable of embedded and high-level programming for the microcontroller and server
    Worked together extensively to solve the mechanical and electrical aspects of the project
  • 22. Q & A
