  • 2. Overview for everyone
  • 3. ICS Software Mission
    Provide a student-based, innovative software solution.
    Create functionality not available in commercial, off the shelf software.
    Support a "smart" house.
  • 4. What makes a house smart?
    Requires data:
    Need to know the current and historical "state" of major house systems.
    Requires control:
    "Smart" implies ability to take action.
    Requires integration:
    Within house: actions based upon knowledge of *all* systems, not one.
    Outside of house: ability to interact with Facebook, smart phones, etc.

  • 6. UI Example
  • 7. Milestone 2 goal
    Implement monitoring and control for all five house systems.
    Due in April, 2011.
    Explore the "design space" of monitoring and control capabilities.
    The following slides show our assumptions for Milestone 2 about each system.
  • 8. Aquaponics
    Monitoring:
    Circulation
    Dead Fish
    Elec. Conduct.
    Nutrients
    Oxygen
    pH
    Temperature
    Turbidity
    Water Level
    Control:
    Feed fish
    Harvest fish
    Add nutrients
    Adjust pH
    Set temperature
    Set water level
  • 9. HVAC
    Monitoring:
    Temperature
    Control:
    Set temperature
  • 10. Photovoltaic
    Monitoring:
    Instantaneous power
    Cumulative energy
    Control:
    (No control)
  • 11. Electricity Consumption
    Monitoring:
    Instantaneous power consumption
    Cumulative energy
    Control:
    (No control.)
  • 12. Lighting
    Monitoring:
    Monitor each room individually:
    Lighting level
    Lighting enabled
    Lighting color
    Control:
    Control each room individually:
    Lighting level
    Lighting enabled
    Lighting color
  • 13. Issues to ponder
    What is the "sweet spot" for monitoring and control capabilities that:
    Enables innovation beyond present commercial software;
    Provides maximum opportunities for "smart" behavior;
    Is within budget.
    Brainstorm:
    What else can we monitor/control?
    What other kinds of "smart" are possible?

  • 15. Details of Milestone 2
    Non-programmers can stop watching now.
  • 16. Milestone 1 API (review)
    ihale-api.jar provided:
    Interface for repository (DB).
    Interface for commands.
    Backend:
    Implemented both interfaces.
    Frontend:
    Used the backend implementations.
    Simulator:
    Didn't need either, used HTTP API
  • 17. Milestone 2 API
    ihale-api.jar
    Provides interface for repository (DB).
    Provides interface for commands.
    Provides implementation of DB!
    Backend:
    Implement commands.
    Use iHale API repository implementation.
    Frontend:
    Use Backend implementation of commands
    Use iHale API repository implementation.
  • 18. iHale API repository
    Uses enumerated types to specify:
    System names
    State variable names
    Command names
    Room names
    Provides ~60 methods for retrieval of:
    The most recent state value for any system/state variable combination.
    A list of historical data points for anysystem/state variable combination.
    New persistent data:
    "System Status Messages"
  • 19. Benefits
    "API Dictionary" is now hard-coded
    No strings attached.
    Front end can create sample repository data for testing/development.
    No need to wait for backend.
  • 20. on to the demo
