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.

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?

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 any system/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.
