摘要

Device and system for characterizing vibrations in rails, system and method of approach detection of trains comprising said device and / or system, and method to detect the breakage of a rail using the system to characterize vibrations in rails. # Device to characterize vibrations in 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 is propagates along the rail, obtaining a digitized vibration signal (SVD), transmitting the digitized vibration signal (SVD) measured by the acquisition module to characterize through the digital processing of the digitized vibration signal (SVD) by means of the module processing, obtaining an estimate of the power spectral density (PSD) of the vibrate signal digitized ratio (SVD) as a function of frequency and time and estimate whether the estimate of the power spectral density (PSD) of the digitized vibration signal (SVD) corresponds to a train.
