Abstract
The invention relates to a computer-implemented method for detecting an anomaly of a rolling equipment rolling on rails of a railway resting on a rail support. This method comprises a decomposition (DECOMP) by discrete wavelet transform of a measurement signal (S) transmitted by a strain sensor detecting the deformation of the rail support into an approximation signal (AJ) and a residual signal (RJ) and a search (RECH-PA) for outliers (PA) in the residual signal (RJ) in order to detect an anomaly of the rolling equipment.
