Intelligent Detection and Classification System for Rail Surface Defects Based on Eddy Current

This work presents a system to detect squats on rails based on a device that monitors the train wheel's oscillation frequency. In it, the sensor should be installed directly on the service trains. It uses wavelet power Spectrum in Frequencies between 1060-1160 Hz and a simple threshold for Squat identification. This work is limited to squats detection for preventive maintenance.
