This thesis focuses on improving an embedded bearing fault detection algorithm deployed on the COSAMIRA Edge platform.

The objective is to perform a state-of-the-art analysis of carrier frequency selection techniques (e.g., kurtogram-based methods, Protrugram, Infogram, IESFOgram etc…”) and evaluate their suitability for embedded implementation.

Main challenges include:

– Reliable automatic selection of the optimal demodulation band

– Robustness to speed variation and operational noise

– Low computational and memory footprint

– Real-time feasibility on embedded hardware

– Clean and efficient C++ implementation

– The outcome will be an adaptive, embedded-ready carrier frequency selection module enabling more reliable and earlier bearing fault detection.
