  • the second method is based on satellite-based positioning using GPS signals. However, this method fails in mountainous regions, where many tunnels etc. prevent the transmission of the GPS signals.
  • the invention is based on the object of providing a method, a system and a user device for locating rail vehicles on a rail network which does not have the disadvantages of existing systems, and which in particular functions independently of the topography and independently of the position Sufficiently precise location is permitted and, if possible, requires no complex infrastructure to be installed in addition to the existing rail network infrastructure.

  • Main signals have been used, a display mounted in the operator's console can directly show current signals. Furthermore, depending on the method of use of the method according to the invention, the number of bays in a rail network that are expensive to maintain can also be reduced.
  • the mobile radio transmission system has a transmission network and a multiplicity of mobile user devices which cooperate with the transmission network.
  • the installations of the transmission network in particular its transmission stations (base stations) are essentially stationary.
  • the simplest method for determining the location information is to assign the user device to the transmission station of the network that is closest to its location.
  • the location area corresponds to the sphere of activity of the transmission station.
  • the location area is the overlap area of the spheres of activity.
  • Even more precise information about the location of the user device can be determined if not only the functional groups of transmission stations are evaluated, but also the duration of the signal transmission (signal duration) between user device and transmission station is recorded and included in the determination of the location. With the inclusion of such a distance measurement over the signal duration in the location, the location area is recorded as essentially lying on an arc around a transmission station. If the user device can make contact with three or more transmission stations of a current mobile phone network, the location of a mobile device can be determined with accuracy to a location area with a maximum dimension of approx. 30 m by recording the signal duration and using a suitable calculation algorithm. Further improvements can be achieved if, in addition to the signal runtime, transmission characteristics such as reflections are also included.

Abstract

Selon l"invention, pour déterminer la position d"un véhicule sur rails (2) se déplaçant sur un réseau ferroviaire, une information de localisation est obtenue par le fait qu"un appareil d"utilisateur, se trouvant dans ledit véhicule sur rails et pourvu d"une unité de réception et/ou d"émission, entre en contact avec au moins une station de transmission (3) atteignable d"un système de transmission de téléphonie mobile. A partir de cette information de localisation, la position du véhicule sur rails est déterminée par le fait qu"elle est corrélée avec des informations cartographiques relatives au réseau ferroviaire. Ce système permet l"utilisation de dispositifs de téléphonie mobile existants en combinaison avec une représentation existante, par exemple vectorielle, du réseau ferroviaire, et peut donc ainsi être mis en oeuvre de façon simple et bon marché.
