Definitions

  • the invention relates to a method for detecting broken rails and to a device of this type.
  • the term "rail breakage detection” here includes not only rail breakages but all dangerous structural changes to the rail, in particular also notches, cuts or breaks.
  • Rail breaks can lead to serious accidents in railway traffic, rail breaks even to major disasters. Therefore, there is a need to detect rail breakages at an early stage so that preventive repairs to the rail can avoid accidents and major disasters.
  • track circuits are used for rail break detection.
  • the disadvantages are, above all, the lack of reliability of the evaluation and the dependence of the measuring sensitivity on the effects of weathering, in particular with regard to snowfall and rainfall.
  • a detection of a rail break by means of track circuit is only possible if the rail is already completely broken.
  • the object of the invention is to specify a method and a device for rail break detection which eliminate these disadvantages and, moreover, enable a greater measuring sensitivity and a higher reliability of the evaluation.
  • the aim is also to avoid impairments to the regular train traffic as a result of rail breakage detection.
  • the object is achieved by evaluating on the vehicle side a time profile of at least one sensed rolling signal, in particular a rolling noise or a rolling oscillation, on at least one wheel axle of the rail vehicle with regard to changes with respect to the time course with intact rail.
  • the object is also achieved by a device in which the rail vehicle has at least one sensor assigned to at least one wheel axle for detecting a time course of a roll-off signal, in particular a rolling noise or a roll-off vibration, the sensor having an evaluation device for comparing the current time History is associated with the time course with intact rail.
  • the sensor is firmly connected to the wheel axle of the rail vehicle, so that the vibration behavior is detected at the attachment point.
  • the measuring signal changes, in particular the rolling noise or the rolling oscillation.
  • the magnitude of the change depends on the extent of the damage.
  • With sufficient sensitivity of the sensor creates an early warning system for incipient rail breaks. There- repairs can be carried out before the emergence of acutely dangerous conditions. It is also advantageous that no trackside installations are required.
  • the sensed roll-off signal is also largely weather-independent. Reliability and availability of claimed rail break detection are much higher than in the known methods.
  • the measurement can be carried out by any rail vehicle of the regular driving operation. A slower or special measuring vehicle is not required.
  • rolling signals of a plurality of wheel axles of the rail vehicle are pushed one above the other according to their mutual measuring time distance and cross-correlated, wherein rail vehicle related statistical Abrollsignalanowski eliminated and remaining rail-related Abrollsignalanmaschine be evaluated with respect to rail break-induced peaks.
  • rail vehicle noise for example bearing noise and general roll noise, which typically represents statistical noise, can be eliminated.
  • rail-related Abrollsignalanmaschine that repeat through the measurement of several, especially one behind the other, axes.
  • the principle is that the rolling vibrations of the axle are recorded on at least two consecutive axes and correlated against each other in a speed-dependent manner. This makes it possible to filter out the rail-related irregularities while suppressing the vehicle-induced disturbing vibrations.
  • Route atlas which includes the location of switches and other track facilities.
  • the route atlas serves to determine the time of an expected track-side fault and to assign the corresponding fault pattern. The knowledge of the cause of the fault does not confuse it with a fault caused by a rail break.

Abstract

L'invention concerne un procédé de détection de rupture de rail ainsi qu'un dispositif correspondant. Selon l'invention, pour atteindre une fiabilité et une disponibilité élevées en l'absence d'équipements côté voie, on analyse l'allure dans le temps d'au moins un signal de roulement détecté au moyen de capteurs, notamment un bruit de roulement ou une vibration de roulement, au niveau d'au moins un essieu du véhicule ferroviaire afin d'identifier d'éventuelles modifications par rapport à l'allure dans le temps lorsque le rail est intact.
