Definitions

  • the present invention relates to a method and system for detecting a derailment of at least one axle of a rail vehicle.
  • Derailments often cause very high damage to rail infrastructure in railways, such as rails, sleepers, train control technology and the like, and also pose a major safety risk.
  • long, heavy trains is a derailment for a train driver often not visible.
  • derailed vehicles are dragged along a long way, on which they usually damage the infrastructure facilities to a great extent.
  • An early detection of a derailment could stop the train in question and drastically reduce property damage. Since derailed railway vehicles also represent a high security risk, which can lead to serious railway accidents, for example, as a result of a violation of the gauge, an early detection of derailment also contributes significantly to the safety of man and the environment.
  • the present invention is therefore based on the object of specifying a method and a system for detecting a derailment of at least one axis of a rail vehicle, which is characterized by a relatively low cost of components to be installed and also reliably detects derailments in a timely manner.
  • the weight of a pulling axle leads to a compression of the track bedding, which is transmitted to the track carrier element fixedly connected to the rail.
  • This compression is referred to in professional circles as the pumping of the track and is characterized by a relatively steady initially to a maximum asymptotically rising and then from the maximum asymptotically sloping course, which tends to form lower frequencies in a frequency spectrum.
  • the distance between two track support elements equipped with an acceleration sensor may be between 10 and 5000 meters.
  • the received warning signal which allows identification of the warning unit deducting logic unit, it makes sense when the warning signal occurs when the rail traffic controlling instance identifies the rail vehicle or train after receipt of the warning message and measures to stop the rail vehicle or the train initiates.
  • the identification of the train can for example be based on the real-time data of a train control system, in which the location of the offset of the warning signal is equated with the train, which is located in the track block that includes this location and thus occupies it.
  • the command to stop can then be sent either directly to the driver's cab via a signal box and a Radio Block Center and requests the driver to immediately make an emergency stop.
  • a direct spark of the train driver from the control center or the immediate dissolution of the Movement Authority could be provided.
  • the signal box the next signal to display a HALT signal term.
  • the logic unit may comprise means for energy production and / or energy storage.
  • photovoltaic elements and related Energy storage can thus ensure the power supply of the logic unit and the acceleration sensor.
  • a contribution to the energy supply can also be made by the telepowering signal radiated at the head of the train, which, for example, feeds the energy required to transmit the ETCS telegrams inductively into the balise in the case of ETCS balises.
  • FIG. 1 schematically shows a system 2 for detecting a derailment of at least one axle 4 (wheels 4a and 4b) of a rail vehicle not shown here.
  • the rail vehicle continues along two rails 6, 8.
  • the rails 6, 8 are mounted on a sleeper body 10 which rests on a ballast bed 12.
  • Mounted on the sleeper body 10 (or other attached parts) is an acceleration measurement unit 14 that includes an acceleration sensor 16 and a logic unit 18.
  • an energy store 20 is provided, which is fed by a mounted near the track photovoltaic panel 22.
  • the acceleration measuring unit 14 it is possible to measure and evaluate the mechanical vibrations that occur when the rail vehicle passes by. This measurement is based on the relationship that a movement of the rail vehicle on the rails 6, 8 leads to a compression of the ballast bed 12.
  • the frequency spectrum of this time course will be enriched by high-frequency components according to a frequency analysis, which is quite clear in the comparison with the desired course according to the sequence (a). can be detected and thus determine a derailment. Furthermore, the pure value of the acceleration could also be compared with the determinable limit value a max in the desired course (a). These comparisons and the associated transformation into the frequency domain are carried out by the logic unit 18.
  • the acceleration measuring unit 14 wirelessly transmits a warning message 24, which also includes a sensor identifier for locating the acceleration measuring unit 14, to a control system 26.
  • This warning message is connected by the control system 26 with the train number of the trip, with which the train concerned can be identified.
  • the control system 26 then performs, for example, an automatic intervention in its further journey and stops the train at the next light signal.
  • the acceleration measuring unit 14 can be realized in the form of an integrated circuit and include the acceleration sensor 16, a microprocessor and a module for communication (eg for GSM, GSM-R or the like).
  • the measurement data of the acceleration sensor 16 are digitized by the microprocessor and transferred for example by means of an FFT in the frequency spectrum.
  • the Data then analyzed by the microprocessor and in case of violation of limit values (eg setpoint course a in FIG. 2 ) the warning message 24 discontinued.
  • derailments according to the granularity of equipped with acceleration measuring units 14 emerging bodies 10 can be detected shortly after their occurrence and the train by an active engagement, which is also automatically triggered, are stopped at its onward journey. Damage to the rail infrastructure as well as, of course, severe railway accidents as a result of derailment can at least be severely restricted without requiring a direct connection to the rail vehicle, including an elaborate sensor system for recognizing a derailment on each rail vehicle.
