Zusammenfassung

Netzwerke von Sensoren für verschiedene Messgrößen stellen zunehmend das Rückgrat für eine Vielzahl von Anwendungsgebieten in beispielsweise Industrie, Maschinenbau und Umweltüberwachung dar. Dabei spielt das Zusammenführen der Daten (Sensorfusion) eine zentrale Rolle in der Anwendung und ist im Allgemeinen ein gut untersuchtes Forschungsgebiet. Die Berücksichtigung metrologischer Grundprinzipien wie Kalibrierung, Messunsicherheiten und damit Rückführung auf das SI-Einheitensystem für vergleichbare und reproduzierbare Messergebnisse ist jedoch vergleichsweise wenig untersucht. Dieser Beitrag diskutiert Grundsatzfragen, stellt Lösungsansätze aus dem aktuell laufenden EMPIR-Projekt “Metrology for the Factory of the Future” (Met4FoF) vor und gibt einen Ausblick auf zukünftige Forschungsfelder. Dabei fokussiert sich der Artikel auf das Anwendungsfeld der sog. „Industrie 4.0“ als „Fabrik der Zukunft“.

Abstract

Networks of sensors for different measured variables increasingly represent the backbone for a multitude of application areas, for example in industry, mechanical engineering and environmental monitoring. The merging of data (sensor fusion) plays a central role in the application and is generally a well investigated field of research. However, the consideration of metrological basic principles such as calibration, measurement uncertainties and thus traceability to the SI unit system for comparable and reproducible measurement results is comparatively little investigated. This article discusses fundamental questions, presents solutions from the current EMPIR project “Metrology for the Factory of the Future” (Met4FoF) and gives an overview of future research fields. The article focuses on the field of application of the so-called “Industry 4.0” as the “Factory of the Future”.
