The modular and intelligent spectrometer system "SmartSpectrometer" developed by Fraunhofer IOSB enables the monitoring of quality-relevant material parameters in real-time. Individual solutions for quality and process control can be implemented easily and cost-effectively using various modules. The evaluation of the spectroscopic measurement data is performed by embedded AI (artificial intelligence) at the sensor level so that calibrated quality and material parameters can be transferred directly to programmable logic controllers. Areas of application can be found in the food industry, agriculture or the chemical and pharmaceutical industries. This technology can also be used in the recycling of plastics and textiles.

The SmartSpectrometer modules are integrated using the open communication interface OPC-UA (Open Platform Communications Unified Architecture), which ensures interoperable data and information exchange within and between different automation levels in the sense of Industry 4.0. Through the comprehensive collection and evaluation of spectroscopic measurement data and the exchange of production-relevant information, production processes can be optimised, quality increased and resources saved.

The analysis of the spectroscopic measurement data is done by embedded AI (artificial intelligence) at the sensor level. A new method allows the migration of the calibration, which eliminates the complex and time-consuming development of the calibration models when replacing the sensors or when using several measuring points.
