Fraunhofer IZFP has developed a flexible NDE4.0 platform concept that consists of several complementary technology modules. Each of them demonstrates different features and innovations for future NDE4.0 devices and sensor systems as well as options for a beneficial integration in the IIoT. Generally speaking, the prototype system is our R&D approach to gain experience and advanced knowledge about the way of developing and implementing required features for future NDE4.0 sensor systems. Together with partners from industry, the lab prototype is used for a proof of concept in specific applications of NDE4.0 sensor systems.
The SmartInspect system contains interfaces for innovative interaction with users. SmartInspect is an intelligent assistance system that is designed especially to support and to help inexperienced operating personnel (human-machine-interaction HMI for NDE4.0) and can be used for UT, ET or micromagnetic multiparameter testing.
As we are generating only relevant data during data acquisition (e.g. by means of compressive sensing) the AR visualization can be streamed not only to AR displays but also to remote places via internet. NDE4.0 communication protocols (like OPC UA and DICONDE data format) can be supplied by the electronic modules and software of SmartInspect. These features offer completely new options for remote services and NDE4.0 workflows and for for training and education in NDE4.0.
Thus, advanced defect reconstruction algorithms are an essential element for real-time imaging of NDE results for flaw and defect visualization. For UT we combine compressed sensing with SAFT reconstruction (synthetic aperture focusing technique). The result is our real-time reconstruction algorithm “progressive-SAFT” that is for the first time also demonstrated for data acquisition during arbitrary manual scanning movement with our SmartInspect platform. For UT assistance in manual inspection, visualising the data in 2D (C-Scan) or even 3D (volumetric display, e.g., via AR display) eases the interpretation of the acquired inputs.
