Metrology for heterogeneous sensor networks and Industry 4.0

Abstract

Abstract Networks of sensors for different measured variables increasingly form the backbone for a variety of applications in, for example, 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 research area. However, the consideration of metrological basic principles such as calibration, measurement uncertainties and thus traceability to the SI system of units for comparable and reproducible measurement results has been investigated comparatively little. This article discusses fundamental questions, presents approaches to solutions from the currently running EMPIR project “Metrology for the Factory of the Future” (Met4FoF) and gives an outlook on future fields of research. The article focuses on the field of application of the so-called “Industry 4.0” as the “factory of the future”.
