Definitions

  • the invention is based on a method according to the preamble of claim 1 and on an apparatus according to claim 2.
  • a method and a device for carrying out this method are known, according to which a head-end station is provided in one of several passenger carriages forming a railroad train. At least one high-frequency cable is guided through each car, into which an amplifier for amplifying the high-frequency signals to be transmitted is looped in one direction.
  • the directionally correct, manual switching of the high-frequency cables that can be connected via plug-in connectors requires qualified personnel and a relatively high expenditure of time.
  • the invention has for its object to develop a method according to the preamble of claim 1 and an apparatus for carrying out the method such that the high-frequency, directionally correct switching of the transmission path in a vehicle unit, which consists of vehicles arranged in any sequence and any vehicle direction, with the least possible effort in terms of personnel and time.
  • This object is achieved by the application of the measures specified in claim 1.
  • This has the advantage that, regardless of the use of the vehicles in a first position or a second position rotated by 180 °, the high-frequency switching of the transmission path in the vehicles is carried out automatically after prior checking.
  • a preferred application for the method according to the invention and the device for carrying out this method are passenger trains.
  • 10 denotes a vehicle unit, which comprises a plurality of mechanically coupled vehicles 11, 12, 13 and 14.
  • the first vehicle 11 is equipped with a head station 15, and the other vehicles 12, 13 and 14 each contain a vehicle station 16.
  • the head station 15 and the vehicle stations 16 are connected to one another via two high-frequency cables 20, 21; 22, 23 connected to the ends of each vehicle connector elements 24, 25; 26, 27 have.
  • two high-frequency cables connected in parallel are provided (UIC standard 568), and two connector elements 24, 25; 26, 27 form a high-frequency connector 30 and 31.
  • the high-frequency connector 30 is coupled between the vehicles 11 and 12 as well as the high-frequency connector 31 between the vehicles 12 and 13; however, all other high-frequency connectors are not coupled.
  • FIG. 2 shows the structure of a vehicle station 16 in one of the vehicles 12 to 14, namely in the vehicle 12.
  • the high-frequency cables 20, 21 and 22, 23 are connected to a first to fourth connection 34 to 37 (1 ... 4) of a switching device 40 belonging to the vehicle station 16.
  • a fifth connection 38 (5) is connected firstly to an input of a high-frequency amplifier 41 and secondly to a time control 43 via a first detector circuit 42 (D1).
  • a sixth connection 39 (6) of the switching device 40 is connected to the output of the high-frequency amplifier 41 via a high-frequency coupler 48, which is preferably a directional coupler.
  • this connection is connected via the branch of the high-frequency coupler 48 and a second detector circuit 44, which includes a high-frequency generator 47 for generating a high-frequency signal HFM, via an inverter 49 to the timing controller 43, the output 45 of which is connected to a seventh connection 46 (FIG. 7) Switching device 40 is connected.
  • the seventh connection 46 forms the control input for the switching device 40.
  • the vehicle station 16 of the vehicle 12 first determines on which of the high-frequency cables 20, 21; 22, 23 there is a first high-frequency signal HF1 emitted by a head-end station. For this purpose, the time control 43 of the vehicle 12 switches the switching device 40 on from time to time in such a way that the third connection 3 and the fifth connection 5 are connected in a first time period a; see. Scheme in Fig. 3, in which the periods a to f are designated.
  • the connection between the connections 2 and 5 is opened and a connection between the connections 1 and 5 is established.
  • the second detector circuit 44 (D2) is in the time segments a to d via the connection 5 and the high-frequency amplifier 41 also in succession with the high-frequency cables 20 to 23; however, it has no function with this algorithm.
  • the first algorithm which ends when the connection between the connections 1 and 5 is retained, is followed by a second algorithm, by means of which the coupling state of the high-frequency connectors 30 and 31 between the vehicles 12 and 13 is determined.
  • the second algorithm begins with the switching device 40 being influenced in a time period e by the output signal of the first detector circuit 42 (D1) via the time control 43 in such a way that a connection is established between the connections 6 and 3.
  • the second high-frequency signal HFM passes through the high-frequency coupler 48 and the interconnected connections 6 and 4 and the high-frequency cable 23 to the coupled high-frequency connector 31 between the vehicles 12 and 13.
  • the connections between the connections 1 and 5 and 6 and 4 remain, so that the high-frequency signal HF1 via the high-frequency cable 20 of the Vehicle 12, the high-frequency amplifier 41, the high-frequency cable 23 and the high-frequency connector 31 between the vehicles 12 and 13 reaches the high-frequency cable 21 of the vehicle 13.
  • the second detector circuit 44 would also detect a reflection of the second high-frequency signal HF2 in the time segment f and repeat the test process. After one or more repetitions, the test process, controlled by the time sequence controller 43, can be suspended for a longer period of time and then started again.
  • the timing described in connection with the diagram in FIG. 3 applies analogously.
  • the vehicle 11 in FIG. 1 is not in front of the vehicle 12, but behind it, that is to say that the vehicles 11 and 13 are exchanged. Since the high-frequency amplifier 41 of the vehicle 12 can only amplify first high-frequency signals HF1 in one signal direction, the switching device 40 must be programmed so that, for example in a first algorithm, it first connects the connections 3 and 5 and then the connections 4 and 5.
  • the second algorithm can follow the switching position in which the connections 4 and 5 are connected, in which the connections 6 and 2 or 6 and 1 are connected in succession are so that the second detector circuit 44 can determine which high-frequency connector is coupled between the vehicle 12 and the vehicle 13 then located at the first position.
  • a second high-frequency signal HF2 'or HF2'' generated by a high frequency generator 51.
  • the high-frequency generator 47 and the inverter 49 according to FIG. 2 are thus omitted.
  • the frequency of the second high-frequency signal HF2 should preferably be outside the transmission frequency range of the high-frequency amplifier 41.
  • the frequency of the second high-frequency signal HF2 is selected below the transmission frequency range of the high-frequency amplifier 41.
  • the second high-frequency signal HF2 ′ or HF2 ′′ is preferably fed to the fifth connection 38 of the switching device 40 via a high-frequency switch 52.
  • the switching device 40 in the vehicle 13 successively establishes the connections shown in the diagram in FIG. 5, algorithm 1. At the same time, a connection between the connections 3 and 6 is established in the vehicle 12. Since the connector 30 between the vehicles 12 and 13 is open, the second detector D2 of the vehicle 12 cannot evaluate the second high-frequency signal HF2 ′′ of the vehicle 13.
  • connection between the connections 4 and 6 of the vehicle 12 is then established.
  • the detector 44 of the vehicle 12 detects the second high-frequency signal HF 2 ′′ and causes the switching device 40 to maintain the switching position 4-6.
  • the first detector 42 in the vehicle 13 recognizes the first high-frequency signal HF1 and allows the switching device 40 in the vehicle 13 to remain in the switching position 2-5.
  • a vehicle station 160 has a pilot-controlled amplifier 410, the gain of which is regulated as a function of a pilot signal U P which is also transmitted by the combat station 15.
  • a pilot evaluation circuit 411 belonging to the pilot-controlled amplifier outputs a specific control signal U S when a pilot signal is detected.
  • the control signal U S controls a time sequence controller 430 in an analogous manner to the output signals of the first detector circuit 42 in FIG. 2.
  • the pilot evaluation circuit 411 thus takes over the function of the first detector circuit 42 in FIG. 2.
  • a pilot signal U P which is reflected on the connector part 26 and corresponds to the second high-frequency signal HF2, is fed as a measurement signal to the second detector 44 (D2) via a high-frequency coupler 413, for example a directional coupler.
  • the signal emitted by the second detector then controls the time control 430 after being inverted by the inverter 49.
  • the further function is analogous to the diagram in FIG. 3.
  • the method according to the invention and the device for carrying out the method can also be used in an active bidirectional high-frequency transmission system when using two different frequency bands for the forward and reverse directions.
  • the unidirectional amplifier 41 (FIG. 2) is replaced by an amplifier unit which amplifies in two directions.
