To date, standards are not machine-understandable, which means they have to be read, understood and entered into appropriate systems by humans. In a pilot project with the Competence Center for Electrotechnical Standardization, we investigated how augmented reality technology can be used to perform a product test against the standard completely digitally.
As digitization progresses, it is common practice in product manufacturing to create a virtual image - the so-called digital twin - that accompanies the development throughout its entire life cycle. This enables predictive maintenance to be carried out during the use phase, for example.
In addition, engineering data can already be checked against applicable standards during the development phase - provided that the respective standards are available in a machine-readable form. To this end, however, a format must first be defined that precisely and unambiguously represents all normative content, such as the requirements and recommendations or the information from formulas and tables.
In order to approach this issue as pragmatically as possible and based on the necessary parameters, in the first step of the joint project with the Deutsche Kommission für Elektrotechnik im DIN und VDE we transferred a modern switch cabinet, including some electronic components, into a digital twin. This switch cabinet can be displayed in full and to scale via augmented reality at any location.
The video shows a switch cabinet projected into the field of view via augmented reality. Thanks to the technical possibilities of the Microsoft HoloLens data glasses used, the user can "interact" with the built-in components of the switch cabinet - i.e. the components can be removed from the cabinet, rotated and viewed from all sides.
In addition, further technical details, drawings, etc. about the component and any standard that needs to be taken into account can be superimposed.
