Die Leitungen müssen innerhalb des Schienenfahrzeugs verlegt werden. Das Verwenden von Leitungen ist aufgrund der Rohstoffpreise, beispielsweise für Kupfer, und der Herstellungskosten der Leitung, neben den Kosten für die Verlegung und für die entsprechenden konstruktiven Vorkehrungen, teuer. Für die Verbindungen der In conventional rail vehicles, lines are used for communication between two railway vehicles adjacent to a train and for communication from one end of a rail vehicle to its other end. The cables must be laid inside the rail vehicle. The use of pipelines is expensive due to raw material prices, such as copper, and the cost of producing the piping, in addition to the cost of installation and the related design precautions. For the connections of the
Leitungen zwischen den Schienenfahrzeugen werden Stecker an den Kuppelstellen verwendet. Stecker sind immer anfällig bezüglich der Kontaktierung, da in den Lines between the rail vehicles are used connectors at the coupling points. Plugs are always prone to contact, since in the

Schienenfahrzeugen benachbart eingestellten Schienenfahrzeugen übertragen zu können. Die erfindungsgemäße Datenübertragungsvorrichtung ist des Weiteren so gestaltet, dass an den beiden Enden des Schienenfahrzeugs zweite Sende- und/oder Empfangseinrichtungen angeordnet sind, um Daten durch drahtlose Kommunikation zwischen den beiden Enden des Schienenfahrzeugs übertragen zu können.

Empfangseinrichtungen angeordnet. An jedem der beiden Enden ist somit eine erste Sende- und/oder Empfangseinrichtung und eine zweite Sende- und/oder Receiving devices arranged. At each of the two ends is thus a first transmitting and / or receiving device and a second transmitting and / or
Empfangseinrichtung angeordnet, so dass im Schienenfahrzeug jeweils zwei erste Sende- und/oder Empfangseinrichtungen und zwei zweite Sende- und/oder  Receiving device arranged so that in the rail vehicle in each case two first transmitting and / or receiving means and two second transmitting and / or
Empfangseinrichtungen angeordnet sind. Die ersten Sende- und/oder Empfangseinrichtungen führen dabei die Kommunikation zwischen zwei in einem Verbund von Schienenfahrzeugen benachbart eingestellten Schienenfahrzeugen, beispielsweise zwei in einem Zug benachbarten, miteinander gekoppelten Waggons durch, während die zweiten Sende- und/oder Empfangseinrichtungen die Kommunikation von einem Ende des Schienenfahrzeugs zu seinem anderen Ende durchführen.

Empfangseinrichtungen verwendet werden. Da dadurch jedoch nur eine Kommunikation in eine Richtung möglich ist, ist es vorteilhaft, dass die Einrichtungen sowohl Sende- als auch Empfangsfunktionen haben, um eine Kommunikation in beiden Richtungen entlang eines Schienenfahrzeuges bzw. zwischen zwei benachbarten Receiving devices are used. However, since only a one-way communication is possible thereby, it is advantageous that the devices have both transmitting and receiving functions for communication in both directions along a rail vehicle or between two adjacent ones

Schienenfahrzeuge zeichnet sich vor allem dadurch aus, dass für die Kommunikation zwischen den beiden Enden eines Schienenfahrzeugs auf Leitungen verzichtet werden kann, so dass die Kosten für die Leitungen, ihre Verlegung sowie ihre Wartung eingespart werden kann. Des Weiteren kann bei der Kommunikation zwischen zwei Schienenfahrzeugen auf Steckverbindungen verzichtet werden, so dass einerseits die Kosten für die Steckverbindungen entfallen und andererseits die Störanfälligkeit der Steckverbindungen entfällt. Nach einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, die ersten Sende- und/oder Empfangseinrichtungen so zu gestalten, dass die drahtlose Kommunikation zwischen zwei in einem Verbund von mehreren Fahrzeugen benachbart eingestellten Schienenfahrzeugen mit einer gerichteten Funkstrecke durchgeführt werden kann. Die ersten Sende- und/oder Empfangseinrichtungen an den Enden der Schienenfahrzeuge, mittels denen zwischen zwei in einem Verbund von Schienenfahrzeugen benachbart eingestellten Schienenfahrzeugen kommuniziert werden kann, weisen dabei Antennen auf, die eine kegelförmige Sendekeule aufweisen, d.h. eine Sendekeule mit einem kleinen Winkel. Dadurch werden die Funksignale zielgerichtet von der ersten Sende- und/oder Empfangseinrichtung am Ende eines Schienenfahrzeugs zur ersten Sende- und/oder Empfangseinrichtung, die am Ende des benachbarten Schienenfahrzeugs angeordnet ist, übertragen. Die daraus resultierende gerichtete Funkstrecke verringert die Möglichkeit von externen Störern. Rail vehicles are characterized in particular by the fact that it is possible to dispense with lines for the communication between the two ends of a rail vehicle, so that the costs for the lines, their installation and their maintenance can be saved. Furthermore, in the communication between two rail vehicles can be dispensed with connectors, so that on the one hand eliminates the cost of the connectors and on the other hand eliminates the susceptibility of the connectors. According to an advantageous embodiment of the invention, it is provided to design the first transmitting and / or receiving devices such that the wireless communication between two rail vehicles adjacently set in a group of several vehicles can be carried out with a directional radio link. The first transmitting and / or receiving devices at the ends of the rail vehicles, by means of which can be communicated between two rail vehicles adjacently set in a composite of rail vehicles, in this case have antennas having a conical transmitting lobe, ie a transmitting lobe with a small angle. As a result, the radio signals are targeted by the first transmission and / or receiving device at the end of a rail vehicle to the first transmitting and / or receiving device, which is arranged at the end of the adjacent rail vehicle transmitted. The resulting directed radio link reduces the possibility of external interferers.

Zusätzlich wird eine drahtlose Kommunikation zwischen den beiden in einem Verbund von Schienenfahrzeugen benachbart eingestellten Schienenfahrzeugen sowie zwischen den Enden der Data transmission provided between in a composite of rail vehicles adjacent rail vehicles and a wired data transmission between the two ends of the rail vehicle. In this case, on the one hand, as in the case of conventional vehicles, a line-bound communication is carried out between two rail vehicles adjacently set in a train and between the two ends of a rail vehicle. In addition, wireless communication is established between the two rail vehicles adjacently connected in a composite of rail vehicles and between the ends of the rail vehicles
Schienenfahrzeuge selbst durchgeführt. Dadurch wird ein redundanter, zusätzlicher Kommunikationskanal geschaffen. Dadurch wird eine höhere Zuverlässigkeit der Kommunikation erreicht, was insbesondere für sicherheitskritische Anwendungen relevant ist, und wodurch ein höherer SIL-Level nach IEC 61508 erreicht werden kann. So können beispielsweise höhere Zuverlässigkeiten für die Übertragung von Rail vehicles carried out themselves. This creates a redundant, additional communication channel. As a result, a higher reliability of the communication is achieved, which is particularly relevant for safety-critical applications, and as a result of which a higher SIL level according to IEC 61508 can be achieved. For example, higher reliability for the transmission of
Bremssignalen erreicht werden, da neben der leitungsgebundenen Kommunikation eine zusätzliche drahtlose Kommunikation genutzt werden kann.

In a further advantageous embodiment of the invention, the data transmission device according to the invention is set instead of a line-bound data transmission between adjacent in a composite of rail vehicles
Schienenfahrzeugen sowie einer leitungsgebundenen Datenübertragung zwischen den beiden Enden der Schienenfahrzeuge vorgesehen. Die ausschließlich drahtlose Rail vehicles and a wired data transmission between the two ends of the rail vehicles provided. The only wireless

Schienenfahrzeugen sowie zwischen den beiden Enden eines Schienenfahrzeugs ersetzt damit die herkömmliche leitungsgebundene Datenübertragung zwischen und innerhalb von Schienenfahrzeugen. Dadurch kann auf die Verlegung von Leitungen verzichtet werden. Auch können im Schienenfahrzeug angeordnete Funktionseinheiten, wie beispielsweise Klimaanlagen, ohne Steuerleitungen betrieben werden, was die Kosten für die Verlegung von Leitungen und auch die Materialkosten senkt. Rail vehicles and between the two ends of a rail vehicle thus replaced the conventional wired data transmission between and within rail vehicles. This makes it possible to dispense with the laying of lines. It is also possible to operate functional units arranged in the rail vehicle, such as, for example, air conditioning systems, without control lines, which reduces the costs for the laying of cables and also the material costs.
In einer weiteren vorteilhaften Ausgestaltung ist die Datenübertragungsvorrichtung so gestaltet, dass sie Bremssignale zum Ansteuern von Schienenfahrzeugbremsen übertragen kann. Ansteuerungssignale für die Bremsen von Schienenfahrzeugen werden bei herkömmlichen Fahrzeugen über die Druckluftleitungen oder über leitungsgebundene Kommunikation übertragen. Wird ein Bremssignal mittels In a further advantageous embodiment, the data transmission device is designed so that it can transmit brake signals for driving rail vehicle brakes. Control signals for the brakes of rail vehicles are transmitted in conventional vehicles via the compressed air lines or via line-bound communication. If a brake signal by means
Druckluftleitung übermittelt, so kann das drahtlos übertragene Signal aufgrund der schnelleren Laufzeit dem Ende eines Zuges signalisieren, dass gleich ein  Compressed air line transmitted, the wirelessly transmitted signal can signal the end of a train due to the faster running time that equal to one
Bremsvorgang eingeleitet wird. Damit können am Ende des Zuges bereits Braking process is initiated. This can already be done at the end of the turn
Vorkehrungen getroffen werden, um schneller den Bremsvorgang einzuleiten, wenn die Druckluft-basierte Hauptbremsleitung den Bremsvorgang anfordert. Auch das Lösen der Bremse kann damit beschleunigt werden. Die Übertragung der Bremssignale ist damit möglich, ohne Leitungen für die Signalübertragung vorsehen zu müssen. Arrangements are made to initiate the braking process more quickly when the compressed air-based main brake line requests the braking operation. Also, the release of the brake can be accelerated. The transmission of the brake signals is thus possible without having to provide lines for signal transmission.
In einer weiteren vorteilhaften Ausgestaltung ist die Datenübertragungsvorrichtung so gestaltet, dass sie auch Zugtrennungen erkennen kann. Durch die permanente In a further advantageous embodiment, the data transmission device is designed so that it can also detect train separations. By the permanent
Kommunikation zwischen den einzelnen Schienenfahrzeugen kann bei ausbleibender Kommunikation das ungewollte Abkoppeln von einzelnen Schienenfahrzeugen eines Zugverbands frühzeitig dem Triebfahrzeugführer gemeldet werden. Ein erfindungsgemäßes Schienenfahrzeug ist mit einer erfindungsgemäßen Datenübertragungsvorrichtung, wie sie vorstehend beschrieben wurde, ausgerüstet. Dadurch kann im Schienenfahrzeug auf das Verlegen von Leitungen verzichtet werden, es kann eine höhere Zuverlässigkeit der Kommunikation erzielt werden, da auf störanfällige Steckverbindungen zwischen den Leitungen benachbarter Communication between the individual rail vehicles can be reported early in the absence of communication, the unintentional uncoupling of individual rail vehicles of a train association to the driver. An inventive rail vehicle is equipped with a data transmission device according to the invention, as described above. As a result, the laying of lines can be dispensed with in the rail vehicle; higher reliability of the communication can be achieved, since interference-prone connections between the lines are adjacent
Schienenfahrzeuge verzichtet werden kann, und es kann, wenn die erfindungsgemäße Datenübertragungsvorrichtung parallel zu einer leitungsgebundenen Kommunikation des Schienenfahrzeugs verwendet wird, eine Redundanz und damit eine noch höhere Zuverlässigkeit und eine höhere Sicherheitseinstufung für die Kommunikation erzielt werden. Rail vehicles can be omitted, and it can, if the data transmission device according to the invention is used in parallel to a wired communication of the rail vehicle, a redundancy and thus an even higher reliability and a higher security rating for the communication can be achieved.
In einer erfindungsgemäßen Bremssteuerung für ein Schienenfahrzeug werden die Bremssignale durch eine erfindungsgemäße, vorstehend beschriebene In a brake control according to the invention for a rail vehicle, the brake signals are generated by an inventive, as described above
Datenübertragungsvorrichtung übertragen. Dadurch können im Unterschied zu einer Übertragung von Bremssignalen mittels Druckluftleitungen die Signale schneller übertragen werden, so dass insbesondere Schienenfahrzeuge, die am Ende eines Zuges eingestellt sind, schneller den Bremsvorgang einleiten können, als dies bei einer Übertragung der Bremssignale mittels Druckluftleitungen möglich ist. Data transfer device transmitted. As a result, in contrast to a transmission of brake signals by means of compressed air lines, the signals are transmitted faster, so that in particular rail vehicles, which are set at the end of a train, can initiate the braking process faster than is possible with a transmission of the brake signals by means of compressed air lines.

Die Aufweitung der Sendekeulen muss dabei nur so groß sein, dass durch die Kegelwinkel Veränderungen der gegenseitigen Lage der beiden ersten Sende- und Empfangseinrichtungen 103 durch Kurvenfahrten eines Zuges sowie durch die bei der Fahrt üblicherweise auftretenden lateralen Bewegungen zwischen zwei benachbarten Schienenfahrzeugen 101 ausgeglichen werden können. Im in Fig. 2 dargestellten Ausführungsbeispiel werden Daten zwischen den zwei benachbarten Schienenfahrzeugen 101 zusätzlich über Datenleitungen 1 17 übertragen.

The widening of the transmission lobes only has to be so great that changes in the mutual position of the two first transmitting and receiving devices 103 can be compensated for by cornering of a train and by the lateral movements between two adjacent rail vehicles 101 that usually occur during the journey. In the exemplary embodiment illustrated in FIG. 2, data between the two adjacent rail vehicles 101 are additionally transmitted via data lines 17. Due to the additional wireless data transmission with the invention
Datenübertragungsvorrichtung wird damit ein zusätzlicher, redundanter Data transmission device is thus an additional, redundant
Kommunikationskanal geschaffen, durch den Daten parallel oder alternativ übertragen werden können. Dadurch ist es insbesondere bei Störungen der Datenleitung 1 17, und hier insbesondere der Steckverbindungen möglich, Daten zwischen benachbarten Schienenfahrzeugen 101 stets sicher zu übertragen. Dadurch kann insbesondere für sicherheitskritische Anwendungen, beispielsweise Bremssteuerungen, ein erhöhtes Sicherheitsniveau bereitgestellt werden.
