- a method and a device for carrying out this method are known, according to which a head station is provided in one of several passenger carriages forming a railroad train. Each car carries at least one high-frequency cable 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 performing 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 order and any vehicle direction , is managed with as little personnel and time expenditure as possible.
- 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 (UlC 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 is 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 first 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 (7 ) the 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. 3, in which the time segments a to f are designated.
- the time control 43 opens the connection between the connections 4 and 5 in the time segment c and bridges the connections 2 and 5
- the connection between the connections 2 and 5 is opened and a connection is established between the connections 1 and 5.
- a first algorithm is thus ended; see. 3.
- the second detector circuit 44 (D2) is also connected in succession to the high-frequency cables 20 to 23 in the time segments a to d via the connection 5 and the high-frequency amplifier 41; however, it has no function with this algorithm.
- a second algorithm follows, determined by which the coupling state of the high-frequency connector 30 and 31 between the vehicles 12 and 13 'will be.
- 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 differing from the first high-frequency signal HF1 second Hochfre ⁇ -frequency signal HFM passes the high frequency generator 47 via the Hochfrequenzkopp ⁇ ler 48, the terminals 6 and 3 and 'the high frequency cable 22 to the non-coupled high-frequency connector 30 between the vehicles 12 and 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 procedure. After one or more repetitions, the test process can be controlled for a longer period of time by the time sequence controller 43 and then started again.
- the time sequence 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.
- the high-frequency amplifier 41 of the vehicle 12 can amplify first high-frequency signals HF1 only 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 after 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 so that the second detector circuit 44 can ascertain which high-frequency plug connection is coupled between the vehicle 12 and the vehicle 13 then located at the first position.
- a second high-frequency signal HF2 1 or HF2 is generated "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 below the transmission frequency range of the high-frequency amplifier 41 is selected.
- 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 according to FIG. 5, algorithm 1 At the same time, a connection is established between the connections 3 and 6 in the vehicle 12.
- the second detector D2 of the vehicle 12 cannot evaluate the second high-frequency signal HF2 "of the vehicle 13 .
- the connection between the connections 4 and 6 of the vehicle 12 is then established.
- the detector 44 of the vehicle 12 recognizes the second high-frequency signal HF2 "and causes the switching device 40 to switch positions 4-6
- the first detector 42 in the vehicle 13 detects 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 also transmitted by the combat station 15.
- a pilot evaluation circuit 411 belonging to the pilot-controlled amplifier outputs a specific control signal U ⁇ when a pilot signal is detected.
- the control signal I controls a time control 430 in an analogous manner to the output signal 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 for example reflected on the connector part 26 and corresponding 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 with an active bidirectional high-frequency transmission system using two different frequency bands for the forward and reverse directions.
- the amplifier 41 (FIG. 2) transmitting in one direction is replaced by an amplifier unit which amplifies in two directions.
