Problems solved by technology

However, OPC UA instead defines concepts for expressing semantic descriptions within specification documents, implying a lack of formal semantic representation
The lack of a formal semantic representation has the main drawback that queries within the OPC UA information model are intricate
Although OPC UA defines a query language for accessing the information model, there is as yet no framework for implementing query requests, not least due to the semantic description scattered within the information model of OPC UA for querying High complexity imposed

Embodiment Construction

[0018] The evolution of networking between computers and computing devices has culminated in the so-called »Internet of Things«. The Internet of Things in an industrial context refers to the concept of functionally connecting things (or industrial entities) to enable complex interactions, for example for tracking, monitoring and management of more complex industrial entities. Clearly, industrial entities can vary in complexity, ranging from individual sensors, devices, equipment, systems, subsystems, or ultimately completed processes in an industrial setting.

[0019] Industrial entities are typically equipped with ample storage, communication, and computing resources. Utilizing these entities to bring the concept of the cloud down to the user has been given the name fog networking. Fog networking is a technology that operates to use resources already present at the edge of the cloud to provide a network that can support low latency and backbone bandwidth savings.

Abstract

The proposed embodiments relate to a method for querying industrial data amongst a plurality of industrial entities. More specifically, the present embodiments relate to a method for querying industrial data stored in a triple store, using a transformed query expression, wherein the triple store includes an aggregated ontology of industrial data. The proposed embodiments enable efficient querying of an aggregated and transformed OPC UA information model. Currently there is no product-ready tool implementation for querying an OPC UA information model available. The proposed embodiments allow for performing query operations imposed to a plurality of industrial entities including skill-matching, onboarding of devices into machinery, data-mining etc.

Description

technical field [0001] This embodiment relates to a method for querying industrial data among multiple industrial entities. More specifically, the present embodiment relates to a method for querying industrial data stored in a triplestore comprising an aggregated ontology of industrial data using a transformed query expression (aggregated ontology). Background technique [0002] Past industrial automation system components have traditionally been interconnected by private networks using standard industrial protocols for access and data exchange. The development of current and future automation systems has placed considerable emphasis on exchanging semantically rich information aimed at enabling flexible manufacturing scenarios. [0003] To overcome the still existing low-level signal communication in industrial automation systems, a protocol called OPC UA has been proposed for enhancing field-level communication to semantic level. OPC UA (Open Platform Communication Unifi...
