Definitions

  • the invention relates to a method for operating a mobile device in a railway system with at least one laid next to at least one track optical waveguide, fed in its use as a distributed acoustic sensor light pulses and backscattered light is detected.
  • a method of this kind is described in international patent application WO 211/027166 AI.
  • a rail vehicle is thereby identified on a rail track, that the typical for each rail vehicle driving noise is detected by means of a laid next to the rail track optical fiber.
  • light is fed into the optical waveguide and backscattered light is detected.
  • This backscattered light has a frequency distribution corresponding to that of the noise of the rail vehicle traveling along the optical fiber.
  • the rail vehicle on the rail track can be identified from a comparison of the spectrum of the rail vehicle with the stored frequency spectrum. It is also possible to distinguish rail vehicles from each other, if they have different frequency spectrums in the driving noise, which is usually the case.
  • the object of the invention is to propose a method for operating a mobile device in a railway system with which a mobile device can be identified not only comparatively simple but also particularly reliable.
  • a mobile device with a sound generator adjustable in terms of its frequency spectrum according to the invention is used in a method of the type specified in the introduction, and the sound generator is set in terms of its frequency spectrum by designating a frequency selection to the mobile device; upon detection of the backscattered light, an identification number signal of the mobile device is obtained from the detected frequency selection.
  • An essential advantage of the method according to the invention is that the use of an adjustable sound generator on the mobile device makes it possible to set the sound generator of the mobile device and also each individual sound generator of mobile devices in a railroad track system individually with regard to its frequency spectrum; Each mobile device is therefore designated by its sound generator with a frequency spectrum, the frequency spectra or the identification number signals being managed by the railway system. Therefore, when operating the mobile device in a railway system according to the method of the invention, it is not necessary to determine the frequency spectrum of a mobile device in advance, as is required in the known method. In the method according to the invention, it is relatively easy to assign an identification number in the form of an individually assigned frequency spectrum to the mobile device and to obtain an identification number signal for evaluation with regard to the identification of the mobile device from the backscattered light.

With the assignment of a further frequency selection to the mobile device, it is in fact possible to identify a type class of the respective mobile device in addition to the identification by means of an identification number signal and thus to make the identification of the mobile device particularly reliable.
  • the setting of the sound generator with regard to its frequency spectrum can take place in different ways; For example, it is considered advantageous if a sound generator is used with a manually adjustable frequency spectrum, so the sound generator can be adjusted locally.
  • This frequency spectrum can be predetermined by a center of the railway system and is therefore also known to the control center, so that a mobile device can be reliably identified and classified even with a sound generator set in this way.
  • the sound generator is set from a central frequency spectrum selection module with regard to its frequency spectrum, for example via radio or by wire. In this case, the frequency spectrum in the central frequency spectrum selection module can be selected from the mobile device or centrally and assigned to the sound generator.
  • the identification number signal and / or the classification signal train control equipment and / or train monitoring means are applied, because both the identification number signal and the classification signal good for train control or Train protection and also suitable for train monitoring.
  • the application is preferred in the case of a mobile device in the form of a rail vehicle, because this creates the possibility of simply and reliably identifying and possibly also locating a rail vehicle in the context of the method according to the invention. No further signal communication equipment is necessary. The number of axle counters, balises etc. along the rail track can be greatly reduced.
  • a mobile signal device as a mobile device.
  • a mobile signal device then emits an identification number signal and possibly also a classification signal with the aid of which the operation of the railway system can be reliably controlled on the rails even in the event of malfunctions or impairments-generally characterized by mobile signaling devices.
  • a mobile signaling devices means for controlling and influencing the rail traffic, such as a track-blocking signal device and a slow-travel signal device preferably in question.
  • the invention further relates to a railway system having at least one optical waveguide laid alongside at least one rail track as a distributed acoustic sensor to which a light emitter and light receiver for backscattered light containing Lichtsende- and evaluation assigned, as is also known from the above-mentioned international patent application.
  • the railway system contains at least one mobile device with a sound generator which can be set in terms of its frequency spectrum; the sound generator is communicative with a frequency spectrum selection module for assigning a frequency selection connected to the mobile device and the light emitting and evaluating arrangement is designed such that with her from the backscattered light the Frequenzaus- selection detectable and from an identification number signal of the mobile device can be obtained.
  • the sound generator of the sound generators in a mobile device belonging to a type category of mobile devices is type-class-defining in terms of its frequency spectrum and assigning another one Frequency selection to the mobile device adjustable, and the Lichtsen- de- and evaluation arrangement is designed such that with her from the backscattered light, the further frequency selection detectable and from a classification signal of the mobile device can be obtained.
  • a mobile device can identify itself particularly reliably.
  • the sound generator can be adjusted in the railway system according to the invention in various ways with respect to its frequency spectrum;
  • An advantageous embodiment includes a sound generator, which is connected to a handset for the frequency spectrum.
  • the sound generator is communicatively connected to a central frequency spectrum selection module.
  • the communicative connection of the sound generator with the central frequency selection module can both wired as well as via radio; Also via optical connections, a connection can be produced.
  • the light-transmitting and evaluating arrangement is advantageously communicatively connected to devices for train control, train protection and / or train monitoring.
  • the connection can be wired and wireless and via optical media.
  • the mobile device is preferably a rail vehicle in the railway system according to the invention, because rail vehicles often require reliable identification in their operation in the railway system.
  • the mobile device can also be a mobile signal device, which is preferably understood to mean a track-blocking signaling device or a slow-travel signal device.
  • the invention further relates to a mobile device of a railway system with a sound generator that can be set in such a way as to be representative of its frequency spectrum, that a frequency selection can be assigned to the mobile device.
  • a mobile device of a railway system with a sound generator that can be set in such a way as to be representative of its frequency spectrum, that a frequency selection can be assigned to the mobile device.
  • the sound generator can be advantageously connected to a frequency spectrum selection module which forms a structural unit with the sound generator, which makes it possible to set the frequency selection on site. It has also proven to be advantageous if the sound generator is designed such that it can be set to a class of mobile devices with respect to its frequency spectrum type class designating assignment of another frequency selection to the mobile device.
