Development of a standardized data acquisition prototype for heterogeneous sensor environments as a basis for ML applications in pultrusion

Pultrusion of continuous fiber reinforced profiles has been state of the art for several decades. However, pultrusion in the production environment so far has no or only few sensor data in a heterogeneous sensor environment, has shortcomings in data quality (time synchronization, different formats, different sampling rates, sporadic disconnections and resulting data losses), and insufficient data processing methods are used for process control and optimization. Significant efficiency improvements would therefore still be possible in this respect. The question therefore arises as to how a data acquisition system can be designed that provides heterogeneous data in a standardized and reliable manner for data-based process development and optimization. The aim is therefore to develop a digitized and standardized data acquisition prototype for the continuous production of sustainable profile structures so flexible that the various components of the production line can be adaptively combined in a central data acquisition system. We have therefore screened and selected possible standardized transmission formats in combination with suitable low-cost data acquisition systems for a highly reliable and secure application area. The paper shows a profound concept for a data acquisition prototype based on different low cost control systems for the applicability and testability of the developed requirements regarding data acquisition, processing, and future storage.
