Definitions

  • the present invention relates to a system for testing the correct sequence and transmission of balise and/or loop telegrams intended for an onboard unit of a vehicle.
  • the trackside safety systems (signal box, RBC, in some cases also control technology) must ensure both safe signaling and smooth operations for rail traffic and optimally support the operational processes.
  • capacity throughput
  • cost pressure from infrastructure operators.
  • ETCS European Train Control System
  • the information emitted by the balises is referred to as balise telegrams, the structural structure and coding of which is also regulated in the ETCS specification.
  • the telegrams emitted by the loop cables are also standardized accordingly.
  • balise groups consist of a pair of balises (two balises), which often consists of a fixed data balise (transmission of non-signal image-dependent information) and a transparent data balise (transmission of signal image-dependent information).
  • the document EP3608201 A1 relates to a method for simulating a route journey of a locomotive on a track route equipped with a train control system, the locomotive having an internal vehicle device for train control, which can interact accordingly with a track-side train control system of the track for simulated route travel for the purpose of train control.
  • the present invention is therefore based on the object of specifying a system for testing the correct sequence and transmission of balise and/or loop telegrams intended for an onboard unit of a vehicle, which allows the real conditions to be transferred to the test environment and also the tests the real vehicle speed.
  • the loop telegrams should always be included under the term balise telegrams, unless it is clear in terms of content that it is only a balise telegram or only a loop telegram.
  • the RF element therefore allows the real speed of the train to be simulated over the duration of the switch-on time.
  • the RF element replaces the 27 MHz telepowering lobe emitted by the ETCS antenna during real train operation, with which the balises located on the real track are inductively supplied with the electrical energy required to emit the balise telegrams, i.e. a balise becomes It is only ready to transmit when the train (the ETCS antenna) passes over the balise.
  • balise telegrams Due to the multiplexability of the connection of the balise telegrams, if there are several telegram generator instances whose output balise telegrams are sent out in short succession, a series of balise telegrams can be sent out in short succession, as corresponds, for example, to the crossing of a balise group equipped with several balises, even at high train speed.
  • loop telegrams can also be transmitted to the ETCS antenna (vehicle antenna) before, between or after the individual balise telegrams, although the concept with the RF link is not used for the loop telegrams.
  • a plurality of telegram generator instances are provided, which, when acted upon by the control unit, independently of one another generate the intended balise telegrams.
  • the telegram generator instances thus virtually represent a number of the balises arranged within a real balise group.
  • the programmable signal generator includes a telegram generator for a loop modem, with the telegram intended for the loop cable being controllable with the loop cable is radiated to the vehicle antenna.
  • the Figure 1 shows schematically the structure of a real train protection system on a rail vehicle 2, such as a locomotive or a control car with a driver's cab, and the side of a track 4.
  • a train can consist of the rail vehicle 2 and other attached wagons 6.
  • an OBU control unit for ensuring the train protection functions (usually referred to in technical jargon as an onboard unit (OBU)) on the locomotive/control car and a vehicle antenna 8 associated with this OBU control unit, also called ETCS antenna.
  • OBU onboard unit
  • ETCS antenna a vehicle antenna 8 associated with this OBU control unit, also called ETCS antenna.
  • a pair of balises with two ETCS balises 10a and 10b which can be part of a balise group comprising up to eight balises, not shown here, as part of ETCS, and a loop cable 12 (shown as a dashed line) are provided.
  • balise telegrams 16 are triggered with a 27 MHz telepowering signal 19 emitted by the vehicle antenna 8 (here symbolically shown as a radiation lobe “leading” the vehicle) by the in the balises 10a, 10b induced power triggers the emission of balise telegrams 16.
  • the contents of the balise telegram relevant to the control of the rail vehicle 2 are displayed on a DMI display after reception with the vehicle antenna 8 and evaluation in the OBU control unit and are then relevant for the driver. For example, non-compliance with the calculated braking curve can trigger emergency braking of the rail vehicle 2.
  • Ethernet connection can now be used for this connection.
  • the telegram generator instances 30a to 30e now generate as an output signal exactly the balise telegram 16 and loop telegram 18 intended for transmission.
  • an RF multiplexer 32 controlled by the signal generator 24 the generated balise telegrams 16 are switched through to the balise 26 in a multiplexed order in accordance with the intended series.
  • the balise telegrams 16 are now transmitted via the interface “C” defined and standardized in the ETCS standard (interface “C”) in the same way as a balise telegram 16 would be transmitted to the balise 10a, 10b on the track.
  • the balise 26 therefore represents the actual arrangement of the individual balises in the corresponding balise group in the direction of travel of the rail vehicle 2 due to the multiplexed output of the balise telegrams 16 from the telegram generator instances 30a to 30d.
  • the balise 26 radiates the switched balise telegrams 16 to a first antenna loop 34.
  • a second antenna loop 36 then radiates the balis telegram 16 recorded by the first antenna loop 34 to the vehicle antenna 8 (also called ETCS antenna).
  • the vehicle antenna 8 also called ETCS antenna.
  • an RF switch 40 which is connected between the first and second antenna loops 34, 36 and can be controlled by means of the signal generator 24, for controllably switching on the transmission of the balis telegram 16 received on the first antenna loop 34 to the second Antenna loop 36 is provided.
  • the vehicle antenna 8 connected to the onboard unit OBU now detects the series of balise and loop telegrams emitted by the second antenna loop 36 or the loop cable 12 and feeds these to a correspondingly designed analysis unit.
  • This analysis unit can also be the project designer's computer 22, for example.
  • the analysis unit compares the series of balise telegrams 16 and loop telegrams 18 received by the vehicle antenna 8 with the intended series of balise and loop telegrams and verifies the correct transmission of the series of balise telegrams 16 and loop telegrams 18.
  • balise telegrams 16 and loop telegrams 18 can be mapped based on the tool landscape known today.
  • the so-called series of balise and loop telegrams is made available to the industrial computer 24 in the form of ETCS target system files with the corresponding ETCS telegram contents.
  • the utility program installed there processes the route information, such as the position of the balises, and makes the balise and loop telegrams available to the programmable telegram generator instances 30a to 30e.
