Verfahren und Anordnung zum Betreiben funkzugbeeinflusster spurgebundener Fahrzeuge Method and arrangement for operating train-bound vehicles operated by radio trains
Die Erfindung betrifft ein Verfahren zum Betreiben mittels streckenseitiger und fahrzeugseitiger Sende- /Empfangseinrichtungen funkzugbeeinflusster spurgebundener Fahrzeuge sowie eine diesbezügliche Anordnung. The invention relates to a method for operating by means of track-side and vehicle-side transmitting / receiving devices funkzugbeeinflusster track-bound vehicles and a related arrangement.
Moderne Zugbeeinflussungssysteme für Light Rail Trains und Metros basieren auf einem CBTC - Communication Based Train Control - System, bei dem für die Datenkommunikation ein funkbasiertes Übertragungssystem, typischer Weise WLAN nach IEEE 802.11, verwendet wird. Um eine dichte Zugfolge auf der Strecke zu erreichen, wird der Betrieb der Fahrzeuge vorzugsweise nach dem Moving-Block-Verfahren realisiert. Dabei basiert die Blocksicherung nicht auf vorgegebenen Gleisab- schnittslängen, sondern auf sich vor beziehungsweise hinter den Fahrzeugen her bewegenden Blöcken beziehungsweise Schutzstrecken. Zur Berechnung dieser Blöcke ist eine kontinuierliche Ortung der Fahrzeuge, das heißt, die Bestimmung der genauen Position, Geschwindigkeit und Fahrtrichtung der aufei- nander folgenden Fahrzeuge notwendig. Die Berechnung dieserModern train control systems for light rail trains and metros are based on a CBTC communication based train control system, in which a radio-based transmission system, typically WLAN according to IEEE 802.11, is used for the data communication. In order to achieve a dense train sequence on the route, the operation of the vehicles is preferably realized by the moving block method. The block backup is not based on predetermined track section lengths, but rather on blocks moving in front of or behind the vehicles or protective paths. To calculate these blocks, a continuous location of the vehicles, that is, the determination of the exact position, speed and direction of the following vehicles necessary. The calculation of this

Von den fahr- zeugseitigen Zugbeeinflussungskomponenten werden die Daten bezüglich aktueller Position, Geschwindigkeit und andere Da- ten als Position Reports - PR - an die streckenseitigen Zugbeeinflussungskomponenten übermittelt. Die streckenseitigen Zugbeeinflussungskomponente berechnet aus den Position Reports - PR - die Entfernung der einzelnen Fahrzeuge zum nächsten sicher erreichbaren Zwischenziel und sendet diese Movement Authorities - MA - an die fahrzeugseitigen Zugbeeinflussungskomponenten. Die MA gibt den Fahrzeugen eine Fahrstraße bis zu dem Zwischenziel vor, wobei sichergestellt ist, dass sich zwischen dem Fahrzeug und dem Zwischenziel kein an- deres Fahrzeug befindet. Die MA wird in kurzen Zeitabständen aktualisiert, um den Abstand zwischen zwei Fahrzeugen auf das sichere Minimum zu regulieren. Dieses Verfahren stellt an die Datenkommunikation zwischen den fahrzeugseitigen Komponenten der Zugbeeinflussungseinrichtung und den streckenseitigenBlocks are centralized or decentralized in the trackside components of the train control device. The vehicle-side train control components transmit the data relating to current position, speed and other data as Position Reports - PR to the track-side train control components.

Komponenten der streckenseitigen Zugbeeinflussungseinrichtung hohe Anforderungen, insbesondere bezüglich Bandbreite, Latenz und Verfügbarkeit. Ein bekanntes Kommunikationsverfahren ist in den Figuren 1 und 2 veranschaulicht. Danach wird für die Datenkommunikation ein komplexes, funkbasiertes Übertragungssystem aufgebaut, das aus streckenseitigen Sende- /Empfangseinrichtungen 1 und fahrzeugseitigen Sende- /Empfangseinrichtungen 2 sowie einer zentralen Steuer- und Datenübergabeeinheit 3 besteht. Die streckenseitigen Sende- /Empfangseinrichtungen 1 müssen mit wenigen hundert Metern Abstand entlang der üblicher Weise mehrgleisigen Strecke 4 zwischen Haltestationen 5 verteilt werden (Figur 2), damit jedes Fahrzeug 6 mit mindestens einer streckenseitigen Sende- /Empfangseinrichtung 1 eine Funkverbindung hat, wodurch eine kontinuierliche Kommunikation zwischen fahrzeugseitiger Zugbeeinflussungskomponente 7 und streckenseitiger Zugbeeinflussungskomponente 8 ermöglicht wird. Üblicher Weise sind an beiden Enden des Fahrzeuges 6 Sende- /Empfangseinrichtungen 2 vorgesehen, die über einenComponents of the trackside Zugbeeinflussungseinrichtung high demands, in particular with regard to bandwidth, latency and availability. A known communication method is illustrated in FIGS. 1 and 2. Thereafter, a complex, radio-based transmission system is constructed for the data communication, which consists of trackside transmitting / receiving devices 1 and vehicle-side transmitting / receiving devices 2 and a central control and data transfer unit 3. The trackside transmitting / receiving devices 1 must be distributed with a few hundred meters distance along the usual way multi-track route 4 between holding stations 5 (Figure 2), so that each vehicle 6 with at least one trackside transmitting / receiving device 1 has a radio link, creating a continuous Communication between on-board train control component 7 and track-side train control component 8 is made possible. Normally, 6 transmitting / receiving devices 2 are provided at both ends of the vehicle, which via a
Router 9 mit der fahrzeugseitigen Zugbeeinflussungskomponente 7 verbunden sind. Die zentrale Steuer- und Router 9 are connected to the vehicle-side train control component 7. The central control and
Datenübergabeeinheit 5 steuert den Datenfluss von den fahr- zeugseitigen Sende- /Empfangseinrichtungen 2 über die stre- ckenseitigen Sende- /Empfangseinrichtungen 1 zu der zentralen oder auch dezentralen streckenseitigen Zugbeeinflussungskomponente 8 sowie den Datenübergabeort vom funkbasierten Übertragungssystem 10 zum streckenseitigen Signaltechniknetzwerk 11, das die Daten zu den streckenseitigen Zugbeeinflussungs- komponenten 8 verteilt. Auf diese Weise werden alle von der ortsfesten streckenseitigen Zugbeeinflussungskomponente 8 an das Fahrzeug 6 und von dem Fahrzeug 6 an die streckenseitige Zugbeeinflussungskomponente 8 zu übertragenden Daten über die zentrale Steuer- und Datenübergabeeinheit 3 geleitet. Nachteilig bei diesem bekannten Datenübertragungsverfahren ist vor allem die erforderliche große Anzahl dicht benachbarter streckenseitiger Sende-/Empfangseinrichtungen 1, um sicherzu- stellen, dass die Funkverbindung zwischen Fahrzeug 6 und Streckeneinrichtung nicht abreißt. Data transfer unit 5 controls the data flow from the vehicle-side transceiver 2 via the link-side transceiver 1 to the central or decentralized track-side train control component 8 and the data transfer from the radio-based transmission system 10 to the trackside signal technology network 11, the data to the trackside Zugbeeinflussungs- components 8 distributed. In this way, all data to be transmitted from the stationary track-side train control component 8 to the vehicle 6 and from the vehicle 6 to the track-side train control component 8 are transmitted via the central control and data transfer unit 3 passed. The disadvantage of this known data transmission method is, above all, the required large number of closely adjacent trackside transmitting / receiving devices 1, in order to ensure that the radio link between the vehicle 6 and the track device does not break off.
Der Erfindung liegt demgemäß die Aufgabe zugrunde, ein Verfahren und eine Anordnung gattungsgemäßer Art anzuge- ben, welche eine Reduzierung der streckenseitigen Sende- /Empfangseinrichtungen ermöglichen . The invention is accordingly an object of the invention to provide a method and an arrangement of the generic type, which allow a reduction of the trackside transmitting / receiving devices.
Verfahrensgemäß wird die Aufgabe dadurch gelöst, dass fahr- zeugseitige Sende-/Empfangseinrichtungen, welche temporär keine Funkverbindung zu einer streckenseitigen Sende- /Empfangseinrichtung haben, zu in Funkreichweite befindlichen fahrzeugseitigen Sende-/Empfangseinrichtungen mindestens eines weiteren Fahrzeuges Funkverbindung der Art aufbauen, dass zwischen den fahrzeugseitigen Sende-/Empfangseinrichtungen und einer streckenseitigen Sende-/Empfangseinrichtung eine geschlossene Datenübertragungskette gebildet wird, wobei die streckenseitige Zugbeeinflussungskomponente an die Fahrzeuge der Datenübertragungskette zusätzlich zu den Movement Autho- rity - MA - Daten Identifikations - ID - Daten des vorausfahrenden und des nachfolgenden Fahrzeuges überträgt, und wobei die fahrzeugseitige Zugbeeinflussungskomponente aktuelle Position Report - PR - Daten an die streckenseitige Zugbeeinflussungskomponente und zusätzlich an die fahrzeugseitige Zugbeeinflussungskomponente des nachfolgenden Fahrzeuges überträgt . According to the method, the object is achieved in that vehicle-side transmitting / receiving devices, which temporarily have no radio link to a trackside transmitting / receiving device, to radio within reach vehicle-side transmitting / receiving devices of at least one other vehicle radio link of the kind that build between the vehicle-side transmitting / receiving devices and a track-side transceiver, a closed data transmission chain is formed, wherein the trackside train control component transmits to the vehicles of the data transmission chain in addition to the Movement Authority MA data ID data of the preceding and the following vehicle , and wherein the vehicle-side train control component current position Report - PR - data to the trackside train control component and in addition to the vehicle-side train control component of nachfo vehicle transfers.
Dazu ist gemäß Anspruch 5 eine Anordnung vorgesehen, bei der die fahrzeugseitigen Sende-/Empfangseinrichtungen an beiden Enden des Fahrzeuges angeordnet sind und mit einer Funkver- bindungslogik zur bedarfsweisen Bildung geschlossener Datenübertragungsketten zwischen den Sende-/Empfangseinrichtungen mehrerer Fahrzeuge und einer streckenseitigen Sende- /Empfangseinrichtung verbunden sind. Da die fahrzeugseitigen Sende- /Empfangseinrichtungen erfindungsgemäß auch untereinander kommunizieren, kann die Datenübertragung in beiden Richtungen auch quasi indirekt aufge- baut werden. Dazu enthält die MA, die von der streckenseitigen Zugbeeinflussungskomponente berechnet wird, nicht nur - wie bisher - die bis zu dem nächsten Zwischenziel eingestellte Fahrstraße, sondern zusätzlich die IDs des vorausfahrenden und des nachfolgenden Fahrzeuges, natürlich vorausgesetzt, dass es diese Fahrzeuge gibt. Außerdem sendet die fahrzeugseitige Zugbeeinflussungskomponente PRs - Position Reports- nicht nur an die streckenseitige Zugbeeinflussungskomponente, sondern auch an das nachfolgende Fahrzeug. Aus dem PR des vorausfahrenden Fahrzeuges bestimmt die fahrzeugseitige Zugbe- einflussungskomponente den Abstand zu dem vorausfahrendenFor this purpose, an arrangement is provided according to claim 5, in which the vehicle-side transmitting / receiving devices are arranged at both ends of the vehicle and with a radio link logic for demand-based formation of closed data transmission chains between the transmitting / receiving devices of multiple vehicles and a trackside transmitting / receiving device are connected. Since the vehicle-side transmitting / receiving devices according to the invention also communicate with each other, the data transmission in both directions can also be established almost indirectly. For this purpose, the MA calculated by the track-side train control component not only contains - as before - the route set to the next interim destination, but additionally the IDs of the preceding and following vehicles, provided, of course, that these vehicles exist. In addition, the on-board train control component sends PRs - Position Reports- not only to the trackside train control component, but also to the following vehicle. From the PR of the preceding vehicle, the vehicle-side train-influencing component determines the distance to the vehicle ahead
Fahrzeug, so dass ein Bremswegabstand auf jeden Fall eingehalten wird. Befindet sich kein vorausfahrendes Fahrzeug zwischen Fahrzeug und Zwischenziel, kann die letztgültige MA bis zu dem Zwischenziel abgefahren werden. Aber auch ohne den PR des vorausfahrenden Fahrzeuges erhalten zu haben, kann dasVehicle, so that a braking distance is maintained in any case. If there is no preceding vehicle between the vehicle and the intermediate destination, the last valid MA can be traveled to the intermediate destination. But even without having received the PR of the preceding vehicle, that can
Fahrzeug dem vorausfahrendem Fahrzeug mit einer Geschwindigkeit folgen, die innerhalb der streckenspezifischen Funkreichweite ein sicheres Anhalten ermöglicht. Für den Fall, dass das vorausfahrende Fahrzeug sehr langsam fährt oder steht, kann das nachfolgende Fahrzeug aufrücken, bis die beiden Fahrzeuge direkt kommunizieren können. Vehicle follow the vehicle ahead at a speed that allows a safe stop within the range-specific radio range. In the event that the vehicle in front is driving or standing very slowly, the following vehicle can move up until the two vehicles can communicate directly.
Fahrzeugseitige Sende- /Empfangseinrichtungen dienen quasi als mobile Relay-Stationen, wodurch das Netz der streckenseitigen Sende- /Empfangseinrichtungen erweitert wird. Folglich kann die Anzahl der streckenseitigen Sende- /Empfangseinrichtungen reduziert werden. Auch die umfangreiche Infrastruktur für die, insbesondere als Access Points ausgebildeten, streckenseitigen Sende- /Empfangseinrichtungen, beispielsweise Strom- Versorgung, Netzwerkanbindung, Kabelkanäle, Fundamente, kann entfallen . Vorteilhaft ist darüber hinaus, dass weniger MAs erstellt und übertragen werden müssen, da diese nicht durch die Länge des freien Gleisabschnitts zu dem vorausfahrenden Fahrzeug begrenzt wird. Da PRs lokal zu dem nachfolgenden Fahrzeug wei- tergeleitet werden können, wird das streckenseitige Netzwerk entlastet und die PRs erreichen schneller das nachfolgende Fahrzeug. Die fahrzeugseitige Zugbeeinflussungskomponente errechnet selbständig anhand des PRs des vorausfahrenden Fahrzeuges die Länge des freien Gleisabschnittes bis zu dem vo- rausfahrenden Fahrzeug. Vehicle-side transmitting / receiving devices serve as a sort of mobile relay stations, whereby the network of the trackside transmitting / receiving devices is extended. Consequently, the number of trackside transceivers can be reduced. Also, the extensive infrastructure for, in particular designed as access points, trackside transmitting / receiving devices, such as power supply, network connectivity, cable channels, foundations, can be omitted. It is also advantageous that fewer MAs have to be created and transmitted, since this is not limited by the length of the free track section to the preceding vehicle. Since PRs can be forwarded locally to the following vehicle, the trackside network is relieved and the PRs reach the next vehicle faster. The vehicle-side train control component independently calculates the length of the free track section up to the preceding vehicle on the basis of the PR of the preceding vehicle.
Für das Gesamtsystem ergibt sich durch die Reduktion der an der Datenkommunikation beteiligten Komponenten eine verbesserte Verfügbarkeit bei gleichzeitig verkürztem Daten- Übertragungsweg und damit erhöhter Reaktionsgeschwindigkeit. The reduction of the components involved in the data communication results in improved availability for the overall system with a simultaneously shortened data transmission path and thus increased reaction speed.
Gemäß Anspruch 2 ist vorgesehen, dass bei mehrgleisigen Strecken in die Datenübertragungskette fahrzeugseitige Sende- /Empfangseinrichtungen auf benachbarten Gleisen geführter Fahrzeuge einbezogen werden. Dabei können sowohl Fahrzeuge, die in die gleiche Richtung, als auch Fahrzeuge, die in die entgegengesetzte Richtung fahren, für die Bildung der Datenübertragungskette genutzt werden. Durch das dynamische Verhalten der Fahrzeuge ist es sogar möglich, kurzzeitige Unterbre- chungen der Datenübertragungskette zu tolerieren, ohne den Datenfluss signifikant zu behindern. In entgegengesetzte Richtung fahrende Fahrzeuge sind dabei besonders förderlich. Je dichter die Zugfolge ist, desto leistungsfähiger wird die Datenübertragung. Auch redundante oder mehrfach redundante Datenübertragungsketten oder Datenübertragungskettenabschnitte können gebildet werden. According to claim 2 it is provided that in multi-track routes in the data transmission chain vehicle-side transmitting / receiving devices are included on adjacent tracks guided vehicles. Both vehicles traveling in the same direction and vehicles traveling in the opposite direction can be used to form the data transmission chain. Due to the dynamic behavior of the vehicles, it is even possible to tolerate short-term interruptions of the data transmission chain without significantly hindering the data flow. Vehicles traveling in opposite directions are particularly conducive. The denser the train sequence, the more efficient the data transfer becomes. Redundant or multiply redundant data transmission chains or data transmission chain sections can also be formed.
Zusätzlich oder alternativ zu den Fahrzeugen auf Nachbargleisen sind gemäß Anspruch 3 zwischen den Gleisen angeordnete streckenseitige Sende- /Empfangseinrichtungen einbezogen. Diese stationären Sende- /Empfangseinrichtungen sind insbesondere bei zweiröhrigen Tunnelstrecken vorteilhaft. Dadurch kann die Funkverbindung zwischen Fahrzeugen, die durch Tunnelwandung getrennt sind, hergestellt oder aufrechterhalten werden. Die streckenseitigen Sende-/Empfangseinrichtungen können beispielsweise an Notausgängen, die sich üblicher Weise in regelmäßigem Abstand im Tunnel befinden, installiert werden. Diese besonderen streckenseitigen Sende-/Empfangseinrich- tungen können autonom betrieben werden oder aber mit den anderen streckenseitigen Sende-/Empfangseinrichtungen vernetzt sein . Die Funkverbindungslogik zur bedarfsweisen Bildung geschlossener Datenübertragungsketten ist gemäß Anspruch 6 in einem zwischen den Sende-/Empfangseinrichtungen eines Fahrzeuges angeordneten Router vorgesehen, wobei der Router mit der fahrzeugseitigen Zugbeeinflussungskomponente verbunden ist. Die an den beiden Enden eines Fahrzeuges angeordneten Sende- /Empfangseinrichtungen leiten die von einer fahrzeugseitigen oder streckenseitigen Sende-/Empfangseinrichtung empfangenen Daten über den Router an die fahrzeugseitige Zugbeeinflussungskomponente und/oder an die am anderen Zugende angeordne- te fahrzeugseitige Sende-/Empfangseinrichtung weiter. In addition or as an alternative to the vehicles on neighboring tracks, trackside transmitting / receiving devices arranged between the tracks are included according to claim 3. These stationary transmitting / receiving devices are particularly advantageous for two-tube tunnels. This allows the radio link between vehicles passing through tunnel wall are separated, manufactured or maintained. The track-side transceivers can be installed, for example, at emergency exits, which are usually at regular intervals in the tunnel. These special track-side transceivers can be operated autonomously or can be networked with the other track-side transceivers. The radio link logic for demand-based formation of closed data transmission chains is provided according to claim 6 in a arranged between the transmitting / receiving devices of a vehicle router, wherein the router is connected to the vehicle-side train control component. The transmitting / receiving devices arranged at the two ends of a vehicle transmit the data received from a vehicle-side or trackside transmitting / receiving device via the router to the vehicle-side train-influencing component and / or to the vehicle-side transceiver device arranged at the other end of the train.
Im Router und/oder in anderen Gliedern der Datenübertragungs- kette können die Daten gemäß Anspruch 4 entweder bis zur Weiterleitung oder Verarbeitung temporär zwischengespeichert werden, wobei die Daten nach Ablauf eines Gültigkeitszeitraums vorzugsweise gelöscht werden. Diese Gültigkeit kann entweder generell oder datentypbezogen sein und sich auf die verstrichene Zeit seit Datengenerierung oder auf den zurückgelegten Weg in der Datenübertragungskette beziehen. Die Funkverbindungslogik mit den Algorithmen für die Weiterleitung und Speicherung der Daten kann auch alternativ statt in dem Router direkt in den fahrzeugseitigen Sende-/Empfangseinrichtungen integriert sein. Gemäß Anspruch 7 sind zusätzlich infrastrukturseitige Sende- /Empfangseinrichtungen zur koordinierten Ansteuerung stre- ckenseitiger und/oder fahrzeugseitiger Einrichtungen vorgesehen. Beispielsweise in automatisierten Metrosystemen müssen lokale Prozesse koordiniert werden. Das betrifft zum Beispiel das synchrone Öffnen und Schließen von Fahrzeugtüren und Bahnsteigtüren. Dazu dienen die infrastrukturseitigen Sende- /Empfangseinrichtungen, welche entweder autonom arbeiten oder mit anderen streckenseitigen Sende- /Empfangseinrichtungen vernetzt sind. In the router and / or in other links of the data transmission chain, the data according to claim 4 can either be buffered temporarily until forwarded or processed, wherein the data is preferably deleted after expiration of a validity period. This validity may be either general or data type related and may refer to the elapsed time since data generation or the path traveled in the data transmission chain. The radio link logic with the algorithms for the forwarding and storage of the data can alternatively be integrated directly into the vehicle-side transceiver instead of in the router. In addition, infrastructure-side transmitting / receiving devices are provided for the coordinated activation of route-side and / or vehicle-side devices. For example, in automated metro systems need local processes are coordinated. This concerns, for example, the synchronous opening and closing of vehicle doors and platform screen doors. Serving this purpose are the infrastructure-side transmitting / receiving devices, which either operate autonomously or are networked with other trackside transmitting / receiving devices.

- Dritter Fall: Auf der Strecke 4 befinden sich nur die Fahrzeuge 6.5 und 6.6: Die Datenübertragungskette wird von dem Fahrzeug 6.5 über die streckenseitigen Sende- /Empfangseinrichtungen 1.2 und 1.1 bis zum Fahrzeug 6.6 gebildet .  - Third case: On the line 4 there are only the vehicles 6.5 and 6.6: The data transmission chain is formed by the vehicle 6.5 via the trackside transmitting / receiving devices 1.2 and 1.1 to the vehicle 6.6.
- Vierter Fall: Auf der Strecke 4 befinden sich nur die Fahrzeuge 6.3, 6.4 und 6.6, wobei die Funkverbindung 12 zwischen dem Fahrzeug 6.4 und der streckenseitigen Sende- /Empfangseinrichtung 1.3 gestört ist: Die Datenübertragungskette wird von dem Fahrzeug 6.4 zum Fahrzeug 6.3 und - sobald dieses Fahrzeug 6.3 die Position von 6.2 erreicht hat - über die streckenseitigen Sende- /Empfangseinrichtungen 1.2 und 1.1 bis zum Fahrzeug 6.6 gebildet . - Fourth case: On the route 4 are only the vehicles 6.3, 6.4 and 6.6, the radio link 12 between the vehicle 6.4 and the trackside transmitting / receiving device 1.3 is disturbed: The data transmission chain is from the vehicle 6.4 to the vehicle 6.3 and - as soon as this vehicle 6.3 has reached the position of 6.2 - formed on the trackside transmitting / receiving devices 1.2 and 1.1 to the vehicle 6.6.
Durch diese Datenübertragungsketten, in die mehrere Fahrzeuge 6.1 bis 6.6 integriert sein können, sind bei entsprechender Fahrzeugdichte diverse streckenseitige Sende- /Empfangseinrichtungen 1 zwischen den Stationen 5 entbehr- lieh, wie ein Vergleich zwischen den Figuren 2 und 3 verdeutlicht . By means of these data transmission chains into which a plurality of vehicles 6.1 to 6.6 can be integrated, various trackside transmitting / receiving devices 1 between the stations 5 are dispensable, given a corresponding vehicle density, as a comparison between FIGS. 2 and 3 illustrates.
