Abstract
Advancements within the Internet of Things are leading to a pervasive integration of different domains including also building automation systems. As a result, device functionality becomes available to a wide range of applications and users outside of the building automation domain. In this context, Web services are identified as suitable solution for machine-to-machine communication. However, a major requirement to provide necessary interoperability is the consideration of underlying semantics. Thus, this work presents a universal framework for tag-based semantic modeling and seamless integration of building automation systems via Web service-based technologies. Using the example of the KNX Web services specification, the applicability of this approach is pointed out.
Zusammenfassung
Entwicklungen im Rahmen des Internets der Dinge führen zu einer durchdringenden Integration unterschiedlicher Domänen, zu denen auch Gebäudeautomationssysteme zählen. In Folge wird die Gerätefunktionalität einem großen Kreis von Anwendungen und Nutzern außerhalb der Gebäudeautomation zugänglich gemacht. In diesem Zusammenhang bieten Web Services eine passende Lösung zur Umsetzung von Maschine-zu-Maschine-Kommunikation. Eine wesentliche Anforderung zur Sicherstellung der notwendigen Interoperabilität ist jedoch die Berücksichtigung der zugrundeliegenden Semantik. Deshalb präsentiert diese Arbeit ein allgemeines Framework zur semantischen Modellierung mit Tags und zur nahtlosen Integration von Gebäudeautomationssystemen mit Hilfe von Web Service-basierenden Technologien. Die Anwendbarkeit des Ansatzes wird anhand der KNX Web Services-Spezifikation gezeigt.
