SMART Calibration Platform for a Set of Metrology Equipments: Application for spectrum analyzer

Abstract

With the great progress it has made, metrology is increasingly essential in various fields such as health, biology, food, chemistry and medicine. If we refer to etymology, "metrology" means "science of measurement". The business measurement approach should therefore fall within the realm of rigor and rationality by performing periodic calibration. By using new technologies (IT, Machine learning, etc.), work methods can be innovated by modernizing measurement techniques and by introducing the notion of intelligence. "SMART Metrology" or "intelligent metrology" is therefore required to take care of the automatic calibration and monitoring of equipment and will provide reliable and repeatable measurements, which will be verified by legal metrology. It is therefore used to create SMART measuring instruments that transform measurement results into controlled information. More and more companies are opting for Smart metrology for the simple reason that it modernizes the techniques of taking measurements introducing new concepts, in particular Big Data. This technology offers metrologists the opportunity to develop their profession, allowing them to actively participate in the compliance of measuring instruments and the reliability of measurements in the company. This paper presents a SMART platform for calibrating spectrum analyzers available in a metrology laboratory using Python programming software. This Human Machine Interface (HMI) makes it possible to communicate in real time with the spectrum analyzers, to take measurements automatically, to supervise the instrument remotely in order to carry out the calibration and verification of the equipment and to judge the conformity of the equipment.
