An OSGi based platform supporting industry 4.0 applications for SMEs - H Kornmayer


Published on

OSGi Community Event 2017 Presentation by Harald Kornmaer [DHBW Mannheim]

Building a worldwide IoT infrastructure requires a reliable basic runtime platform. Such a distributed computing system will consist of Cloud computing instances, sensor node, desktop computers and wearables.

This talk explores how DHBW Mannheim, Germany have created the AQUASI research project (an Automated Quality Assurance Application Platform for SMEs in Handcraft Industries) and discusses the real world results and benefits that have been achieved from the exemplary use case of a german SME company, Rombach NUR-HOLZ which have been participating in the project.

This applied research offers an Open Source framework to enable SME companies to build Industry 4.0 application to monitor and assure Quality Assurance across the full product lifecycle form production through the ongoing maintenance after purchase and installation.

The AQUASI framework leaverages OSGi technology and Eclipse projects. Examples include Jetty, JAX-RS connectors with OSGI and Eclipse p2 and e4. . The project started with the development of an Industry 4.0 language using the AQUASI data and communication model to enable faster development of the SME applications.

The talk will include an overview of the project architecture of the AQUASI system including the REST-based communication model that is used, along with UI components and future plans. Attendees will also get to understand some of the project challenges that have been faced and overcome.

  6. 6. OSGI Community Event /EclipseCon Europe13. November 2017 6 The SME Business Challenge • handcraft industry is going industrial production – fraction of pre‐assembled products grows – but: handicraftsmen are still committed to quality • a local SME goes out to the world – house are sold in Baden‐Württemberg, Germany,  Switzerland, Italy, Netherland, Norway, Japan, …  – collaboration with partners worldwide is required  • there is still resistance to green technology – prove that the house lasts long enough
  7. 7. OSGI Community Event /EclipseCon Europe13. November 2017 7 Industrie 4.0 • Targets – horizontal digital integration of engineering in value networks – vertical integration of networked manufacturing systems – improvements in production process and product quality • Versioning reminder 1.0: mechanization • „Steam engines“ 2.0: industrialization • „Production line“  3.0: automatization • „micro controller “ 4.0: computerization • ???

  26. 26. OSGI Community Event /EclipseCon Europe13. November 2017 26 The i40 domain language • we started with simple DSL – based on AQUASi data and communication model  – to enable other SME domains to deliver services  • in high quality • and in short development time • for more platforms than just E4  – Android, UWP, HoloLens – using Eclipse Xtext project • (Thank to the community!) 
  27. 27. OSGI Community Event /EclipseCon Europe13. November 2017 27 Demo Part 3 • Xtext Language – very early stage example – we used the language for the development of the „/cloud“ services and some UI composites already
  28. 28. OSGI Community Event /EclipseCon Europe13. November 2017 28 Our vision • OSGi in the center of the app, in the cloud and on  the edge nodes • simple management of the AQUASI product cloud – even for SMEs • Collected Data and analytics will help to answer questions like:  – How can I construct a wooden house on Hawaii using a  blueprint of a house in Norway?  – How can I control the house heating optimal?  – …
