Device Model Class Diagram

[edit] Events and Device Monitoring

The proposed approach consists on each driver being accountable for posting events notifying changes on the state of its associated actuator devices through the OSGi Event Admin service.

As a general rule, on each state change an event will be posted under the topic "osami/device/statechanged", and its properties will convey information about the type, identity, altered state variable name and new value, and timestamp.

Bearing the different types of devices supported by the platform (class diagram above) the events to be fired are specified in the following tables.

[edit] AcousticSignal

Topic	osami/device/statechanged
Properties	id: device identifier devicetype: "AcousticSignal" statevarname: modified state variable's name value: new value timestamp: value of System.currentTimeMillis at change instant (Long)
State variables	activated: Boolean value

[edit] LuminicSignal

Topic	osami/device/statechanged
Properties	id: device identifier devicetype: "LuminicSignal" statevarname: modified state variable's name value: new value timestamp: value of System.currentTimeMillis at change instant (Long)
State variables	activated: Boolean value

[edit] Light

Topic	osami/device/statechanged
Properties	id: device identifier devicetype: "Light" statevarname: modified state variable's name value: new value timestamp: value of System.currentTimeMillis at change instant (Long)
State variables	lightOn: Boolean value

[edit] PowerSupply

Topic	osami/device/statechanged
Properties	id: device identifier devicetype: "PowerSupply" statevarname: modified state variable's name value: new value timestamp: value of System.currentTimeMillis at change instant (Long)
State variables	powerSupplyOn: Boolean value

[edit] DoorLock

Topic	osami/device/statechanged
Properties	id: device identifier devicetype: "DoorLock" statevarname: modified state variable's name value: new value timestamp: value of System.currentTimeMillis at change instant (Long)
State variables	locked: Boolean value

[edit] WaterValve

Topic	osami/device/statechanged
Properties	id: device identifier devicetype: "WaterValve" statevarname: modified state variable's name value: new value timestamp: value of System.currentTimeMillis at change instant (Long)
State variables	closed: Boolean value

[edit] CoolingDevice

Topic	osami/device/statechanged
Properties	id: device identifier devicetype: "CoolingDevice" statevarname: modified state variable's name value: new value timestamp: value of System.currentTimeMillis at change instant (Long)
State variables	currentValue: Integer value maxLevel: Integer value minLevel: Integer value

[edit] GradualLight

Topic	osami/device/statechanged
Properties	id: device identifier devicetype: "GradualLight" statevarname: modified state variable's name value: new value timestamp: value of System.currentTimeMillis at change instant (Long)
State variables	currentValue: Integer value maxLevel: Integer value minLevel: Integer value

[edit] Blind

Topic	osami/device/statechanged
Properties	id: device identifier devicetype: "GradualLight" statevarname: modified state variable's name value: new value timestamp: value of System.currentTimeMillis at change instant (Long)
State variables	state: Either "stopped", "opening", or "closed"
