Implementation of the Asset Administration Shell Concept to Industrial Augmented Reality Applications

To unify communication across partners in production systems, the German Plattform Industrie 4.0 network specified the Asset Administration Shell (AAS) both as a general concept and a specific data exchange format for assets in Internet of Things contexts. This contribution presents an approach to apply this concept to quality inspection (QI) processes supported by Augmented Reality (AR) assistant systems. It defines the submodels that contain all data required to provide shop floor personnel with necessary information during the process. Furthermore, the approach contains the representation of necessary system and positioning information for correct AR overlay of the QI information on top of the real-world object. Finally, a prototype AAS system implementation for Microsoft HoloLens 2 based on Eclipse Basyx is presented for evaluation and validation purposes.
