Abstract: System and method for synchronizing information model changes between hierarchical systems of a smart factory are disclosed. A model generator instantiates objects for an aggregated information model for each of a plurality of subsystems in the smart factory based on an OPC UA standardized model. A synchronization engine maintains a global timestamp variable for a last successful synchronization performed by a parent OPC UA server for syncing to a second aggregated information model instance stored in a lower level OPC UA server. Model nodes are annotated with a node-wise timestamp in response to a modification to the node. All nodes subject to modification are pushed to a priority queue as a serialized node set format having annotation extensions that include synchronization-relevant data. The first and second aggregated information model are synchronized by updating nodes with the synchronization-relevant data.

Abstract: A novel and advantageous combination of a data interface (e.g., API endpoint) and a dedicated file endpoint having a common ticket system is presented. Quasi-atomic actions are made possible through the use of (at least) one freshly introduced ticket each that links the two endpoints to one another. Files are addressable using type-specific FileProxies as part of the data model, the respective FileProxies implementing the type-specific handling (e.g., reading, writing, changing, deleting).

Abstract: Environmental sound is captured and mapped. Application of a large number of mobile communication terminals embodied as a data supplier leads to extensive, automatic and continual mapping of environmental sound. For sites that are visited relatively frequently and by a plurality of subscribers, a relatively large quantity of remotely transmitted data records for the environmental sound is obtained informally, which permits a more precise depiction of the environmental noise. Commercially available mobile communication terminals may be augmented using simple measures in order to communicate with a central or local mapping system or mapping service directly or indirectly.
