Die nachfolgende Beschreibung bezieht sich im Wesentlichen auf die Anwendung für spurgebundene Verkehrssysteme, ohne dass die Erfindung auf derartige Systeme beschränkt sein soll. Denkbar ist beispielsweise auch die Anwendung bei Auto¬ motive-Systemen oder Industrieanlagen, deren Komponenten über Luftschnittstellen miteinander kommunizieren müssen.The following description refers essentially to the application for track-bound traffic systems, without the invention being restricted to such systems. It is also conceivable, for example, the application in auto ¬ motive systems or industrial plants whose components must communicate with each other via air interfaces.
Zur Überbrückung der Kommunikations-Luftschnittstelle zwi¬ schen zugseitigen und streckenseitigen Funktionseinheiten o- der zwischen Zügen oder Zugteilen werden heute viele unterschiedliche Technologien und Systeme eingesetzt, beispiels- weise Linienleiter, Gleiskreise, Balisen, Datenfunk, Sprechfunk, Mobilfunk oder WLAN (Wireless Local Area Network) . Diese Technologien wurden für verschiedenste Aufgabenstellungen, beispielsweise Zugbeeinflussung, Zugintegritätskontrolle, Fahrgastinformation, Energieverbrauchsoptimierung, Zugriff auf Daten der Fahrzeugsteuerung oder Diagnose- und Instandhaltungsdatenübermittlung entwickelt und unterscheiden sich dadurch grundlegend voneinander. Der Bedarf an komplexen Kommunikationsfunktionen, insbesondere sicherungstechnischer Art, wird mit UTO-Anwendungen (Unattendant Train Operation, fahrerloser automatischer Betrieb) und Multimediaanwendungen weiter steigen. Absehbar sind vor allem CCTV-Übertragungen bezüglich Passagierbeobachtung und Gepäcküberwachung, Notfallmeldeeinrichtungen, zug- und streckenseitig synchroni- sierte Fahrgastinformation sowie Auskunftsysteme im Zug. Problematisch dabei ist die stetig wachsende Systemkomplexi¬ tät, verbunden mit einer hohen Anzahl verschiedener Übertragungskanäle und erheblichen Aufwänden für Test, Integration und Zulassung.To bridge the communication air interface Zvi ¬ rule trainborne and trackside functional units or between trains or train sections many different technologies and systems are used today as beispiels- line cables, track circuits, beacons, radio data transmission, radio communication, cellular or WLAN (Wireless Local Area Network ). These technologies have been developed for a wide range of tasks, such as train control, train integrity control, passenger information, energy consumption optimization, access to vehicle control data or diagnostics and maintenance data transmission, thus fundamentally different. The need for complex communication functions, particularly of a security nature, will continue to increase with Unattendant Train Operation (UTO) applications and multimedia applications. Above all, CCTV transmissions with regard to passenger observation and baggage monitoring, emergency reporting equipment, train and trackside synchronization are predictable. passenger information and information systems on the train. The problem here is the ever growing Systemkomplexi ¬ ity, combined with a high number of different transmission channels and considerable effort for testing, integration and approval.

Nach einer in Anspruch 5 gekennzeichneten vorteilhaften Aus- führungsform werden über vorhandene oder neue Kommunikations¬ kanäle weitere Komponenten an die komponentenspezifischen Schnittstellen angekoppelt. Die Ankopplung kann auf einheitliche Weise, zum Beispiel mittels Plug-In-Technik oder durch dynamisches Aktivieren und Deaktivieren lokal oder temporär verfügbarer Kommunikationskanäle, zum Beispiel mittels Plug- and-Play, erfolgen.

Das Multiplex-The single figure shows schematically an embodiment for a communication system. It can be seen that functional units FU1, FU2 and FU3 communicate on the tension side TS via a multiplex / demultiplexing system MDS with functional units FU4, FU5, FU6... On the stationary side WS. Train-side functional units FU1, FU2 and FU3 can be, for example, train control units or service facilities for the passenger. On the fixed side WS, the functional units FU4, FU5, FU6 ... are mainly train control and control Factory facilities and service facilities for the passenger. In the embodiment, the Funktionsein ¬ need units FU 3 and FU5 unidirectional communication while the other functional units FUL, FU2 FU4 and FU6 communicate bidirectionally. The functional units FU2 and FU3 are connected via a train-side communication bus Bl to the multiplexing / demultiplexing system DMS. On the stationary side WS a stationary communication bus B2 is provided, via which the functional units FU4 and FU5 are connected to the multiplexing / demultiplexing system DMS. The multiplex
/Demultiplexsystem DMS besteht im Wesentlichen aus einem MuI- tiplexer MPXl und einem Demultiplexer DMPXl auf der Zugseite TS und einem Multiplexer MPX2 und einem Demultiplexer DMPX2 auf der ortsfesten Seite WS, die über Kommunikationskanäle COMl , COM2, COM3... miteinander verbindbar sind. In dem Ausführungsbeispiel ist der Kommunikationskanal COM2 ein unidi- rektionaler Kommunikationskanal, während die Kommunikations¬ kanäle COMl und COM3 bidirektional benutzbar sind. Die Schnittstellen zwischen den Multiplexern/Demultiplexern MPXl, MPX2, DMPXl, DMPX2 und den Kommunikationskanälen COMl, COM2, COM3... sind vorzugsweise als Plug-in ausgeführt. Dabei sorgen Hilfsprogramme in den Multiplexern MPXl, MPX2 und den Demul- tiplexern DMPXl, DMPX2 für eine automatische Auswahl der Kommunikationskanäle COMl, COM2, COM3... anhand vorgegebener Aus- wahlkriterien, beispielsweise einer Priorisierung der Übertragung sicherheitsrelevanter Daten. Die Demultiplexer DMPXl und DMPX2 demultiplexen die Informationen aus jedem einzelnen Kommunikationskanal und leiten diese Informationen an die Ziel-Funktionseinheiten FUl, FU2, FU3 zw. FU4, FU5, FU6... wei- ter. Vorzugsweise sind die Datentelegramme dazu mit einer IP- Adresse versehen. Das Kommunikationssystem gestattet ein umfassendes Management von Kommunikationsaufgaben, wobei die vorhandenen Kommunikationskanäle COMl, COM2, COM3... nicht mehr unabhängig voneinander - wie beim Stand der Technik - genutzt werden, so dass sich ein erheblicher Synergieeffekt einstellt./ Demultiplexsystem DMS consists essentially of a Multiplexer MPXl and a demultiplexer DMPXl on the tension side TS and a multiplexer MPX2 and a demultiplexer DMPX2 on the fixed side WS, which can be connected via communication channels COMl, COM2, COM3 ... with each other. In the embodiment of the communication channel COM2 is a unidi- rektionaler communication channel while the communication channels ¬ COMl and COM3 are bidirectionally usable. The interfaces between the multiplexers / demultiplexers MPX1, MPX2, DMPX1, DMPX2 and the communication channels COM1, COM2, COM3 ... are preferably implemented as plug-ins. In this case, auxiliary programs in the multiplexers MPX1, MPX2 and the demultiplexers DMPX1, DMPX2 ensure an automatic selection of the communication channels COM1, COM2, COM3... Using predetermined selection criteria, for example a prioritization of the transmission of security-relevant data. The demultiplexers DMPX1 and DMPX2 demultiplex the information from each individual communication channel and forward this information to the destination functional units FU1, FU2, FU3 between FU4, FU5, FU6... Preferably, the data telegrams are provided with an IP address. The communication system allows a comprehensive management of communication tasks, whereby the existing communication channels COMl, COM2, COM3 ... not more independently of each other - as in the prior art - are used, so that sets a significant synergy effect.
Die Erfindung beschränkt sich nicht auf das vorstehend ange¬ gebene Ausführungsbeispiel. Vielmehr ist eine Anzahl von Va¬ rianten denkbar, welche auch bei grundsätzlich anders gearteter Ausführung von den Merkmalen der Erfindung Gebrauch machen . The invention is not restricted to the above is passed ¬ embodiment. Rather, a number of Va ¬ variants are conceivable, which make use of the features of the invention even with fundamentally different type of execution.
