摘要

# Device to characterize vibration device and system to characterize vibrations in rails, system and method train detection approach comprising said device and / or system and method for detecting the rupture of a rail using the system to characterize vibrations in rails. rails, comprising: an acquisition module, a processing module connected to said acquisition module, a power module, wherein the device is configured to measure, condition and digitize a parameter (P) of the mechanical vibration that propagates through the rail, obtaining a signal digitized vibration (SVD), transmit the signal digitized vibration (SVD) measured by the acquisition module characterized by digital signal processing of digitized vibration (SVD) through module processing resulting in an estimate of the power spectral density (PSD) of the signal vibrates digitized tion (SVD) depending on the frequency and time and estimate if the estimate of the power spectral density (PSD) of digitized vibration signal (SVD) corresponds to a train.
