Definitions

  • the invention relates to an apparatus and a method for track-side monitoring of a position of a parked rail-guided vehicle.
  • the invention further relates to a system for track-side monitoring of a position of a parked rail-guided vehicle and a method for operating the system.
  • the invention further relates to a computer program.
  • this information is particularly advantageous for automatic train operation, since the vehicles can then record an automatic train ride in full performance directly after re-commissioning, without, for example, an initialization drive to locate the vehicle is necessary.
  • the position of the vehicle is usually determined with an accuracy in the meter or decimeter range with a resolution of centimeters.
  • the vehicle control unit can remain switched on, so that it retains the information in its memory, at which position or at which location the vehicle was parked.
  • an on-board vehicle control unit consumes power, which usually has to be provided by a vehicle battery.
  • this can only provide limited energy for the vehicle control unit, so that the vehicle control unit can only be operated for a certain number of hours in order to ensure a correct location of the vehicle can.
  • the object underlying the invention can therefore be seen to provide a device which overcomes the known disadvantages and makes it possible that a rail-guided vehicle can be immediately taken back into an automatic driving operation after a restart.
  • an apparatus for monitoring a position of a parked rail-guided vehicle in infrastructure comprising a detector for detecting a change in location of the parked vehicle and a communication device that is configured to forward the detected location change to a subscriber of the communication network via a communication network communicate.
  • the information about the change of location may include, for example, only the binary information that the location has been changed or not, and / or the relative value of the location change with a resolution in the centimeter or decimeter range and / or the absolute value as a distance between sensor and vehicle.

Rather, according to the invention, it is provided to monitor the vehicle externally, that is to say on the infrastructure side, in particular on the rail side, as to whether this has moved or not. Due to the infrastructure-side, preferably track-side, monitoring of the detector, which can detect on the rail side, whether the parked vehicle has moved or not, a vehicle control unit in the vehicle itself must not remain switched on for locating. As a result, a vehicle battery no longer has to provide energy for operation of the vehicle control unit.
  • rail side in the sense of the present invention means in particular “by rail” (or “from an infrastructure” which is usually located in an environment of the vehicle, for example the rail) and thus means in particular that the monitoring and the detection is not carried out internally in the vehicle itself, but rather externally, ie separately from the vehicle. Rail-side monitoring and rail-side detection are thus performed externally of the vehicle. This means in particular that the device with the detector and the communication device are arranged externally of the vehicle, preferably in the vicinity of the rail.
  • An environment of the rail here designates in particular a region with a distance to the rail of, for example, 100 m, in particular 10 m, preferably 5 m, in particular less than 100 m.

  • An element, which is provided in the vehicle, ie internally in the vehicle, and thus is an element of the vehicle itself, can be referred to in particular as a vehicle-side element.
  • the rail-guided vehicle may be, for example, a train, a car, a railcar or a locomotive.
