Definitions

  • the invention relates to a communication unit for a rail vehicle according to the preamble of patent claim 1 and an associated rail vehicle.
  • Simple rail vehicles such as railway wagons, generally do not have integration into a communication infrastructure of a train comprising several such simple rail vehicles and a tractor. Existing electrical connections are usually used to supply the wagons with electrical energy.
  • This plug-in is a consuming designed connector with numerous individual signal-carrying lines, the individual contacts are prone to contamination and wear.
  • train couplings In normal railway traffic, these couplings must be manually coupled and uncoupled, which is extremely cumbersome and unreliable.
  • recognition of the wake sequence i. which wagons are part of the train and in which order they are coupled
  • a train integrity check i. all originally existing wagons are still part of the train, and in the case of simple passenger coaches a transfer of passenger information, such as Next station, time, delays, etc., not or only with great effort solve.
  • a rail vehicle with a wireless transmission link for transmitting information, operating data and / or commands to adjacent rail vehicles or to an adjacent train part of the same train will be described.
  • the described rail vehicle comprises as part of the transmission line a transmitting / receiving component, which is integrated in a lighting and / or signaling device.
  • Object of the present invention is to provide a communication system for a rail vehicle, which is simple and inexpensive and is particularly suitable for retrofitting of simple rail vehicles.
  • the invention solves this object by a communication unit for a rail vehicle having the features of patent claim 1 and by an associated rail vehicle having the features of patent claim 12.
  • a communication unit for a rail vehicle for carrying out a wireless data exchange with at least one communication unit of adjacent rail vehicles of the same train comprises a self-sufficient energy supply system which has at least one energy conversion unit and one energy supply unit with at least one energy store.
  • the communication unit comprises a transmitting / receiving unit for each end of the rail vehicle. Due to the self-sufficient energy supply, ie the communication unit gains its energy directly on the corresponding rail vehicle, advantageously no supply of external energy is required.
  • the communication unit according to the invention can be used very easily and also makes it possible to retrofit simple rail vehicles of an existing vehicle fleet and their integration into a communication infrastructure of an assembled train.
  • the communication unit according to the invention is characterized by a very low energy consumption.
  • the at least one energy conversion unit is designed as a solar cell or as a generator.
  • the solar cell is arranged, for example, on a roof of the rail vehicle, and the generator is designed, for example, as a dynamo arranged on an axis, which is coupled to a wheel.
  • the at least one energy store is designed as a high-capacity capacitor or rechargeable battery.
  • the power supply unit supplies the components of the communication unit with energy only when necessary. This means that the transmitting and receiving units of the communication unit are mostly switched off and are only supplied with energy when needed.
  • the transmitting and receiving units each comprise a detector unit which detect a signal reception and transmit the detection result to the power supply unit, which supplies the other components of the communication unit with energy in response to the detection result.
  • the power supply unit supplies the detector unit, for example, constantly or periodically or at predetermined times with energy.
  • the detector unit can be realized, for example, with a minimum of energy consumption and therefore can be supplied with energy without problems.

  • a transmission activity can be realized by parallel signaling paths such as RFID or by an ultrasound transmission.
  • the transmitting / receiving units each have a transmitting / receiving antenna, which are arranged outside on end sides of the rail vehicle. Since the corresponding transmit / receive antennas of the corresponding adjacent rail vehicles face each other at a small distance, only a relatively low transmission power is required for data transmission, wherein in addition a good coupling is achieved. In addition, the transmission is insensitive to other transmitters in the area.
  • the communication unit comprises an evaluation and control unit with stored identification information, which receives the corresponding identification information from adjacent rail vehicles of the same train via the transmitting / receiving units for determining a rail vehicle sequence and / or train integrity check and the received identification information with the stored own identification information via the transmitting / receiving units to the adjacent rail vehicles of the same train sends.
  • each evaluation and control unit sends the received identification information plus its own identification information to the respective neighbors.
  • the evaluation and control unit can also service the unlikely case that information from more than one transceiver unit is received by a transceiver antenna, for example because two trains are arranged parallel to one another the transmission line widens to a transmission tree. When the two trains move away from each other, the transmission tree reduces again to a transmission line and the evaluation and control unit can recognize and tolerate repeated double receivers with the information then learned about the Wagon sequence.
  • the evaluation and control unit can couple or decouple passenger information of a passenger information system into the wireless data exchange, the passenger information system outputting the passenger information via an output unit. Additionally or alternatively, the evaluation and control unit can couple or decouple diagnostic information of a diagnostic system of the corresponding rail vehicle into the wireless data exchange. The data rate required for the data coupling or data extraction is low due to the small data volume of the passenger information or the diagnostic information.
  • the communication system according to the invention can be manufactured at a very low price, since required radio technology components are available at low cost in the form of highly integrated circuits.
