Nowadays…


RS-485

5

Two driving forces

Own protocol (Yet Another…)

Own technology Asymmetric

interoperability Vertical solution

(from apps to devices)

Who cares about protocols? Use neutral

representations Loose coupling between

applications and home automation technologies

Mix and merge of technologies


Manufacturers Users / Developers

6

Intelligent Domotic Environment (IDE)


“An environment setting in which existing automation technologies are interfaced by a low cost device (gateway) providing neutral access to the environment for interoperation, intelligent automation scenarios, energy saving, etc.”

“Neutral” representation of a smart environment

Environment Modeling


9

Neutral modeling


Represent the environment as perceived by human inhabitants (i.e., in a technology independent way) Describe the environment setting

Rooms, doors, walls, etc. Describe devices by modeling

What they can do (commands) What they can notify (values, status changes,

alerts,…) In which condition (state) they can be (e.g., on

or off) Support implicit identification

E.g., the lamp on the drawer…

11

DogOnt


Our solution to Neutral modeling Declarative modeling of

Environment Devices

Functionalities (What they can be required to do) Notifications (What they can notify) States (In which condition they can be)

Technology independent Extensible Based on Semantic Web technologies

OWL SPARQL Inference

DogOnt


Stems from EHS taxonomy DomoML

Integrates concepts from ZigBee HA specification EN50523 ZigBee Energy@Home (experimental)

Layered architecture


Foundational classes (Core) Taxonmy roots Relationships

Device-related taxonomies Functionalities, States,... Network Components

DogOnt – Technology issues


One ontology facet to model technology specific aspects dogont:NetworkComponent Technology dependent Not necessarily based on human perception Not necessarily human understandable

Currently supporting KNX, Modbus, Echelon (web service),

Zwave, ZigBee, MyHome (Bticino), TexasInstruments (SmartWatch)

Examples

Extensibility


22

Extensibility


DogOnt (Core) is (can be) extended Using OWL-defined mechanisms Typically

Ontology import owl:SameAs owl:EquivalentClass

Available extensions PowerConsumption ZigBee Effects

23

Power Consumption


Attaches power consumption to device state values Typical Nominal Actual

Power estimation by inference Device consumption in a given state Identify most “reliable” consumption

Actual actually measured Nominal on device label Typical at the category level

Models ZigBee Profiles Clusters

Maps clusters to dogont:Functionalities Models ZigBee specific aspects Currently supports

ZigBee HA ZigBee core (clusters) ZigBee smart energy (clusters) ZigBee Energy@Home (devices and clusters)

Other Applications


Off-line rule property checking E.g., conformance to design/safety rules

On-line rule property checking E.g., computation of safe exits in case of

smoke detection Interoperation rule generation

By exploiting ontology relationships (generates command)
