摘要

Device and system for characterizing vibrations in rails, system and method of detection of approach 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 for characterizing 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 propagates through the rail, obtaining a digitized vibration signal (svd), transmitting the digitized vibration signal (svd) measured by the acquisition module characterize through the digital processing of the digitized vibration signal (svd) by means of the processing module, obtaining an estimate of the power spectral density (psd) of the digitized vibration signal (svd) as a function of frequency and time and estimating whether the power spectral density (psd) estimation of the digitized vibration signal (svd) corresponds to a train.
