DESCRIPTION:

BRIEF SUMMARY
A method and a device for carrying out this method are known according to which a head station is provided in one of a plurality of excursion train carriages forming a railway train. At least one radio-frequency cable is passed through each carriage, into which an amplifier is looped in order to amplify the radio-frequency signals which are to be transmitted, in one direction. The directionally correct, manual through-connection of the radio-frequency cables, which can be connected via plug connectors, is dependent on qualified personnel and takes a relatively long time.
The invention is based on a device for carrying out the method in such a manner that the radio-frequency, directionally correct through-connection of the transmission path in a vehicle unit which consists of vehicles which are assembled in any desired sequence and in any desired vehicle direction, is carried out with as little expenditure as possible in terms of personnel and time.
This is linked to the advantage that irrespective of whether the vehicles are used in a first orientation or in a second orientation rotated through 180.degree. with respect thereto, the radio-frequency through-connection of the transmission path in the vehicles is carried out automatically, after a previous test.
As a result a device for carrying out the method is implemented using means which are particularly simple and operate in an operationally reliable manner.
A preferred application for the method according to the invention and the device for carrying out this method is in excursion trains.
Exemplary embodiments of the invention are explained in more detail in the following text and are shown in the drawing, using a plurality of figures, in which:
FIG. 1 shows a block diagram of a transmission system for a vehicle unit comprising a plurality of vehicles,
FIG. 2 shows a block diagram of a vehicle station according to the invention for a vehicle, in a first configuration,
FIG. 3 shows a scheme for explaining the operation of the vehicle station according to FIG. 2,
FIG. 4 shows a block diagram of a vehicle station for a vehicle, in a second configuration,
FIG. 5 shows a scheme for explaining the vehicle station according to FIG. 4, and
FIG. 6 shows a block diagram of a vehicle station for a vehicle, in a third configuration.
In FIG. 1, 10 designates 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 in each case contain one vehicle station 16. The head station 15 and the vehicle stations 16 are connected to one another via in each case two parallel-connected radio-frequency cables 20, 21; 22, 23, which have plug connector elements 24, 25; 26, 27 at the ends of in each case one vehicle. In each case two parallel-connected radio-frequency cables are provided, for reasons of operating reliability (UIC Standard 568), and in each case two associated plug connector elements 24, 25; 26, 27 form a radio-frequency plug connector 30 and 31. In the exemplary embodiment according to FIG. 1, the radio-frequency plug connector 30 is coupled between the vehicles 11 and 12 in the same way as the radio-frequency plug connector 31 between the vehicles 12 and 13; in contrast, all the other radio-frequency plug connectors are not coupled.
FIG. 2 shows the construction of a vehicle station 16 in one of the vehicles 12 to 14, namely in the vehicle 12. Inside the vehicle, the radio-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 which belongs to the vehicle station 16. A fifth connection 38 (5) is connected firstly to one input of a radio-frequency amplifier 41 and secondly, via a first detector circuit 42 (D1), to a time-sequence controller 43. A sixth connection 39 (6) of the switching device 40 is connected firstly, via a radio-frequency coupler 48 which is preferably a direction coupler, to the output of the radio-frequency amplifier 41. Secondly, this connection
