Description

Die Erfindung betrifft ein Verfahren und ein System zum Steuern von Bahnsteigtüren, die in einem Abstand zueinander angeordnet sind, der dem von Zugtüren eines vom Bahnsteig zu betretenden Zuges entspricht, sowie ein Bahnsteigtürsystem.The invention relates to a method and a system for controlling platform screen doors which are arranged at a distance which corresponds to that of train doors of a train to be entered from the platform, as well as a platform door system.

Ein derartiges Verfahren bzw. System, wie es beispielsweise aus der DE 196 25 193 C1 bekannt ist, kommt insbesondere auf Bahnsteigen mit hoher Frequentierung sowie in Bahnhöfen mit führerlosen Transportmitteln zum Einsatz. Hierbei werden bahnsteigseitig Türen installiert, über die vermieden wird, dass Passagiere auf die Gleise gelangen, solange kein Zug am Bahnsteig steht. Nach Einfahren eines Zuges werden die Türen simultan mit den Zugtüren geöffnet und vor der Abfahrt des Zuges wieder geschlossen. Die Funktion entspricht also gewissermaßen der Funktion von innerer und äußerer Aufzugstür.Such a method or system, as for example from the DE 196 25 193 C1 is known, is used in particular on platforms with high traffic and in stations with driverless means of transport. Here, doors are installed on the platform side to prevent passengers from getting onto the tracks as long as no train is standing on the platform. After entering a train, the doors are opened simultaneously with the train doors and closed again before the departure of the train. The function thus corresponds to the function of inner and outer elevator door.

Die Funktionen der hierbei eingesetzten Türen können in sicherheitsrelevante Funktionen und nicht-sicherheitsrelevante Funktionen unterteilt werden. Z.B. stellt eine Verriegelungsfunktion der Tür, die ein unbeabsichtigtes Öffnen der Tür verhindert, solange kein Zug am Bahnsteig steht, eine Sicherheitsfunktion dar, während beispielsweise die Realisierung einer bestimmten Fahrkurve beim Öffnen der Tür lediglich zur Beschleunigung der Abläufe beiträgt und somit als Komfortfunktion bezeichnet werden könnte. Auch stellt z.B. ein unbeabsichtigter Versuch des Türantriebs, der durch eine Fehlfunktion desselben hervorgerufen werden könnte, kein Sicherheitsrisiko dar, solange über eine zusätzliche Sicherheitsfunktion - wie die oben beschriebene Verriegelung - das tatsächliche Öffnen der Tür verhindert wird.The functions of the doors used here can be subdivided into safety-relevant functions and non-safety-relevant functions. For example, provides a locking function of the door, which prevents inadvertent opening of the door, as long as no train is on the platform, a safety function, while, for example, the realization of a specific travel curve when opening the door only contributes to the acceleration of the processes and thus could be referred to as comfort function. Also, e.g. an inadvertent attempt of the door operator, which could be caused by a malfunction of the same, no security risk, as long as an additional safety function - such as the lock described above - the actual opening of the door is prevented.

Bei Aufzugstüren sind die sicherheitsrelevanten und nicht-sicherheitsrelevanten Funktionen vorteilhaft so aufgeteilt, dass die Antriebssteuerung oder der Umrichter für den Türmotor nur wenige Sicherheitsfunktionen - wie z.B. die Begrenzung der Kraft beim Schließen - realisieren muss.In the case of elevator doors, the safety-relevant and non-safety-relevant functions are advantageously divided so that the drive control or the inverter for the door motor Only a few safety functions - such as limiting the force when closing - must be realized.

Beim Einsatz von Türen auf Bahnsteigen kann aber nicht davon ausgegangen werden, dass - wie bei Aufzügen - der sichere Zustand der Tür der geschlossene Zustand ist, weil:

  1. 1. Aufzüge in hohen Gebäuden in der Regel redundant ausgeführt sind, diese Möglichkeit aber bei Bahnsteigen aufgrund der hierfür erforderlichen zusätzlich notwendigen Investitionen ausscheidet,
  2. 2. als Redundanz zu Aufzügen schon aus Gründen des Brandschutzes üblicherweise Treppen vorhanden sind und
  3. 3. die Möglichkeit, eine Bahnsteigtür von Hand (mechanisch) wie bei einem Aufzug zu entriegeln, einen Bahnsteigausfall bis zur Wartung/Wiederinbetriebnahme der Tür zur Folge hat.
When using doors on platforms but can not be assumed that - as in elevators - the safe state of the door is the closed state, because:
  1. 1. Lifts in tall buildings are usually designed to be redundant, but eliminates this possibility in the case of platforms because of the additional investment required for this purpose,
  2. 2. as redundancy to elevators already for reasons of fire protection usually stairs are present and
  3. 3. The possibility of manually unlocking a platform door by hand (mechanically), as in the case of a lift, will result in a platform failure until maintenance / re-commissioning of the door.

Bei Ausfall eines Aufzugs bleibt das Gebäude als Ganzes betriebsbereit, wenngleich ggf. mit eingeschränkter Performance. Bei Ausfall einer Bahnsteigtür bleibt auch ein betroffener Bahnsteig funktionsbereit. Bei Ausfall eines Bahnsteigs hingegen kommt (zumindest im U-Bahn-Betrieb) in der Regel der Bahnbetrieb zum Erliegen.If a lift fails, the building as a whole remains operational, albeit possibly with limited performance. If a platform door fails, an affected platform remains operational. In the event of a platform failure, on the other hand, railway operations generally come to a standstill (at least in subway operation).

Insofern ist zusätzlich zur Unterscheidung von sicherheitsrelevanten und nicht-sicherheitsrelevanten Funktionen eine Betrachtung der Verfügbarkeit einzelner Komponenten sinnvoll. Eine Komponente oder Funktion kann dann als hochverfügbar gelten, wenn der beabsichtigte Zweck der Funktion bzw. die Funktion der Komponente auch nach Ausfall einer einzelnen Komponente oder eines Teils davon noch gewährleistet ist. Ein System kann als hochverfügbar betrachtet werden, wenn ein einzelner Ausfall einer Komponente des Systems die Gesamtfunktion des Systems nicht unterbindet.In this respect, in addition to the distinction between safety-related and non-safety-relevant functions, it makes sense to consider the availability of individual components. A component or function can then be considered highly available if the intended purpose of the function or the function of the component is still guaranteed even after failure of a single component or a part thereof. A system can be considered highly available if a single failure of a component of the system does not prevent the overall functioning of the system.

Die Realisierung der sicherheitsrelevanten Funktionen kann z.B. durch geeignete Redundanzen oder sonstige (z.B. auch mechanische) Maßnahmen so ausgeführt werden, dass ein Ausfall einzelner Komponenten nicht zu sicherheitskritischen Zuständen führt. Dies könnte beispielsweise dadurch realisiert werden, dass die Steuerung selbst (CPU), die Übertragungsmedien für die Steuersignale (z.B. PROFIBUS / PROFINET / einzelne I/O-Signale) und die Aktoren (z.B. Verriegelungen an jeder Tür redundant ausgeführt werden.The implementation of the safety-relevant functions can be achieved, for example, by means of suitable redundancies or other (eg also mechanical) Measures should be carried out so that a failure of individual components does not lead to safety-critical conditions. This could be realized, for example, by the redundancy of the controller itself (CPU), the transmission media for the control signals (eg PROFIBUS / PROFINET / individual I / O signals) and the actuators (eg interlocks on each door).

Die Realisierung der "Komfortfunktionen" kann auch ohne Redundanz erfolgen, da ein Ausfall solcher Funktionen nicht unmittelbar zu unsicheren Zuständen führt. Eine nicht-redundante Ausführung der Übertragungsmedien und der Aktoren ist also zunächst ausreichend. Allerdings fallen hier bei einer Störung z.B. des Übertragungsmediums gleich alle Bahnsteigtüren aus.The realization of the "comfort functions" can also take place without redundancy, since a failure of such functions does not lead directly to unsafe states. A non-redundant design of the transmission media and the actuators is therefore sufficient initially. However, in case of a disturbance, e.g. the transmission medium equal to all platform screen doors.

Ein solcher Ausfall kann jedoch auch indirekt zu unsicheren Zuständen führen - wie dem Ausbrechen von Panik in einem überfüllten U-Bahnhof. Zudem kann die Vermeidung eines derartigen Totalausfalls der Bahnsteigtüren im Hinblick auf gehobene Verfügbarkeitsanforderungen aufgrund mangelnder Redundanzen in Bahnhöfen (da Bahnsteige in der Regel nicht redundant vorhanden sind) gefordert sein.However, such a failure can also indirectly lead to unsafe conditions - such as the onset of panic in a crowded subway station. In addition, the avoidance of such a total failure of the platform screen doors in terms of increased availability requirements due to lack of redundancy in stations (since platforms are usually not redundant available) may be required.

Der Erfindung liegt die Aufgabe zugrunde, Bahnsteigtüren auf einfache Weise derart anzusteuern, dass das Türsystem eines Bahnsteigs hochverfügbar ist.The invention has for its object to easily control platform doors in such a way that the door system of a platform is highly available.

Diese Aufgabe wird bei einem Verfahren der eingangs genannten Art dadurch gelöst, dass die Bahnsteigtüren in eine Anzahl von zumindest zwei Gruppen unterteilt werden, benachbarte Bahnsteigtüren verschiedenen Gruppen zugeordnet werden, zumindest zwei Steuerungen vorgesehen werden, jede Gruppe über je ein Übertragungsmedium derart mit zumindest einer Steuerung verbunden wird, dass auch jede Steuerung mit zumindest einer Gruppe verbunden ist, und Steuersignale über die Übertragungsmedien an die Bahnsteigtüren übermittelt werden.This object is achieved in a method of the type mentioned in that the platform doors are divided into a number of at least two groups, adjacent platform doors are assigned to different groups, at least two controls are provided, each group via one transmission medium in each case with at least one controller is connected, that also each controller is connected to at least one group, and control signals are transmitted via the transmission media to the platform screen doors.

Die Aufgabe wird weiter gelöst durch ein Bahnsteigtürsystem mit den in Anspruch 4 angegebenen Merkmalen.The object is further achieved by a platform door system having the features specified in claim 4.

Die zu betretenden Züge wie beispielsweise U-Bahnen und Straßenbahnen verfügen über mehrere Türen bzw. - wenn die Züge Zugsegmente (z.B. "Waggons" bei Zügen oder "Abteile" bei U-Bahnen) aufweisen - in der Regel auch über mehrere Türen pro Zugsegment, damit im Normalbetrieb ein schnelles Ein- und Aussteigen zu kurzen Taktzyklen an den Bahnhöfen beitragen kann. Benachbarte Türen stellen deshalb bezogen auf ein Zugsegment des zu betretenden Zuges (bzw. bezogen auf den zu betretenden Zug, falls dieser keine separaten Segmente aufweist, wobei diese Unterscheidung im Folgenden nicht in jedem Fall explizit genannt wird) zumindest eine gewisse Redundanz dar, die zwar beim Ausfall einzelner Türen nicht denselben Passagierdurchsatz erlaubt wie ohne Ausfall, die aber in der Regel ausreicht, um einen Normalbetrieb aufrechtzuerhalten (was auch daran erkannt werden kann, dass des öfteren U-Bahnen mit einzelnen defekten Türen verkehren).The trains to be entered such as subways and trams have several doors or - if the trains have train segments (eg "cars" on trains or "compartments" of subways) - usually also over several doors per train segment, so that in normal operation a quick entry and exit to short clock cycles at the stations can contribute. Neighboring doors therefore represent at least some redundancy with respect to a train segment of the train to be entered (or relative to the train to be entered if it does not have separate segments, this distinction not being explicitly mentioned in the following) failure of individual doors not allowed the same passenger throughput as without failure, but which is usually sufficient to maintain normal operation (which can also be recognized by the fact that often subways operate with individual defective doors).

Werden die Türen an einem Bahnsteig in eine Anzahl von n Gruppen unterteilt, wobei n <= Anzahl der Türen innerhalb eines Zugsegments, müssen zur Ausbildung einer durchgängigen Redundanz lediglich (n-1) redundante Übertragungsmedien ergänzt werden. Fällt nun ein Übertragungsmedium aus, das beispielsweise die erste und dritte Bahnsteigtür mit der Steuerung verbunden hat, so bleibt z.B. die zweite und vierte Bahnsteigtür funktionsfähig. Da die Aufteilung der Türen so gewählt wird, dass benachbarte Türen verschiedenen Gruppen zugeordnet werden, bleibt - wenn z.B. die erste und zweite bzw. die dritte und vierte Tür zu je einem Segment des zu betretenden Zuges gehört - jedes Segment des Zuges trotz Ausfalls einer einzelnen Komponente benutzbar.If the doors are subdivided at a platform into a number of n groups, where n <= number of doors within a train segment, only (n-1) redundant transmission media must be added to form a continuous redundancy. Now fails a transmission medium, for example, has connected the first and third platform door with the controller, it remains. the second and fourth platform door is operational. Since the division of the doors is chosen so that adjacent doors are assigned to different groups, - if e.g. the first and second or the third and fourth door belongs to a segment of the train to be entered - each segment of the train despite failure of a single component usable.

Somit ist das resultierende System zur Steuerung der Bahnsteigtüren hochverfügbar, denn ein hochverfügbares Türsystem kann als solches gelten, wenn die Verfügbarkeit des Bahnhofs durch den Ausfall einer einzelnen Komponente des Türsystems nicht gefährdet ist.Thus, the resulting system for controlling the platform screen doors is highly available, because a highly available door system can be considered as such, if the availability of the station is not endangered by the failure of a single component of the door system.

Darüber hinaus wird durch geschickte Identifikation natürlicher Redundanzen (= mehrere Türen pro Zug / Zugsegment) der erforderliche Mehraufwand auf ein Minimum beschränkt.In addition, clever identification of natural redundancies (= several doors per train / train segment) minimizes the additional work required.

Weitere Ausführungsbeispiele können durch Variation der Anzahl von Gruppen n erreicht werden, wobei gilt, dass mit steigendem n die Funktionsbeeinträchtigungen bezogen auf den ganzen Bahnhof bei Ausfall einer Komponente geringer werden.Further exemplary embodiments can be achieved by varying the number of groups n, with the proviso that as n increases, the functional impairments relative to the entire station become smaller if one component fails.

In einer vorteilhaften Form der Ausgestaltung wird jede Gruppe über je ein Übertragungsmedium mit zumindest einer zweiten Steuerung verbunden, und es werden bei Ausfall einer Steuerung die Funktionen der ausgefallenen Steuerung der zumindest zweiten Steuerung übertragen. Auf diese Weise ist das resultierende Türsystem vollständig immun gegen den Ausfall einer Steuerung, da im Störungsfall die (jeweilige) zumindest zweite Steuerung einspringt, so dass keine Gruppe von Bahnsteigtüren aufgrund des Ausfalls einer Steuerung ausfällt.In an advantageous embodiment of the invention, each group is connected via at least one transmission medium to at least one second controller, and in the event of failure of a controller, the functions of the failed controller are transmitted to the at least second controller. In this way, the resulting door system is completely immune to the failure of a controller, since in case of failure, the (respective) at least second control so that no group of platform doors fails due to the failure of a controller.

In einer weiteren vorteilhaften Ausführungsform weist der zu betretende Zug zumindest zwei Zugsegmente mit jeweils einer Anzahl von Zugtüren auf, und es wird die Anzahl von Gruppen gleich der Anzahl von Zugtüren je Zugsegment gewählt. Auf diese Weise fällt im Falle einer Störung nur eine Tür je Segment aus, wobei dennoch der Mehraufwand an zusätzlichen Übertragungsmedien auf ein erträgliches Maß beschränkt bleibt.In a further advantageous embodiment, the train to be entered has at least two train segments, each with a number of train doors, and the number of groups equal to the number of train doors per train segment is selected. In this way, only one door per segment fails in the event of a malfunction, whereby the additional expense of additional transmission media nevertheless remains limited to an acceptable level.

Im Folgenden wird die Erfindung anhand der in den Figuren dargestellten Ausführungsbeispiele näher beschrieben und erläutert. Es zeigen:

In the following the invention will be described and explained in more detail with reference to the embodiments illustrated in the figures. Show it:
FIG. 1
a schematic representation of a door system with redundant control,
FIG. 2
a schematic representation of a highly available door system according to the invention and
FIG. 3
a further embodiment of a door system according to the invention.

FIG 1 zeigt ein Türsystem mit vier Bahnsteigtüren T1-T4, die über ein Übertragungsmedium M1 mit zwei Steuerungen S1, S2 verbunden sind. Der Anschluss der beiden "Steuerungsstränge" an den einen "Türstrang" erfolgt über den Link L1, der z.B. als Y-Koppler ausgebildet sein kann. Die Steuerungen S1, S2 sind redundant, so dass bei Ausfall einer Steuerung S1, S2 die sicherheitsrelevanten Funktionen von der zweiten Steuerung S1, S2 übernommen werden können. Die Realisierung der "Komfortfunktionen" kann ohne Redundanz erfolgen, da ein Ausfall solcher Funktionen nicht unmittelbar zu unsicheren Zuständen führt. Eine nicht-redundante Ausführung des Übertragungsmediums M1 und der Aktoren in den Türen T1-T4 ist also zunächst ausreichend. Allerdings fallen bei Ausfall des Y-Kopplers L1 oder bei einer Störung im Übertragungsmedium M1 gleich alle Bahnsteigtüren T1-T4 aus, so dass der Bahnsteig insgesamt nicht mehr genutzt werden kann. Da Bahnsteige in Bahnhöfen in der Regel nicht redundant vorhanden sind und zudem auch ein solcher Ausfall indirekt zu unsicheren Zuständen wie dem Ausbrechen von Panik in einem überfüllten U-Bahnhof führen kann, ist eine gehobene Verfügbarkeitsanforderung gefordert. FIG. 1 shows a door system with four platform screen door T1-T4, which are connected via a transmission medium M1 with two controllers S1, S2. The connection of the two "control lines" to a "door line" via the link L1, which may be formed as a Y-coupler, for example. The controllers S1, S2 are redundant, so that if one controller S1, S2 fails, the safety-relevant functions can be taken over by the second controller S1, S2. The realization of the "comfort functions" can take place without redundancy, since a failure of such functions does not lead directly to unsafe states. A non-redundant design of the transmission medium M1 and the actuators in the doors T1-T4 is therefore sufficient at first. However, in the event of failure of the Y-coupler L1 or in the event of a fault in the transmission medium M1, all the platform screen doors T1-T4 fail immediately so that the platform as a whole can no longer be used. Since platforms in stations are usually not redundant and also such a failure can lead indirectly to unsafe conditions such as the onset of panic in a crowded subway station, an upscale availability requirement is required.

FIG 2 zeigt ein Türsystem ähnlich dem in Figur 1 gezeigten, bei dem allerdings die Bahnsteigtüren T1-T4 in zwei Gruppen G1, G2 unterteilt sind und beide Gruppen G1, G2 über je ein Übertragungsmedium M1, M2 - wiederum mittels je eines Links L1, L2 - an je beide (redundante) Steuerungen S1, S2 angeschlossen sind, so dass ein Ausfall einer Steuerung S1, S2 zu keiner Beeinträchtigung des Betriebs führt. Dabei sind die Türen T1 und T3 der ersten Gruppe G1 und die Türen T2 und T4 der zweiten Gruppe G2 zugeordnet, so dass benachbarte Bahnsteigtüren T1-T4 zu unterschiedlichen Gruppen G1, G2 gehören. FIG. 2 shows a door system similar to the one in FIG. 1 in which, however, the platform screen doors T1-T4 are subdivided into two groups G1, G2 and both groups G1, G2 are each connected via a transmission medium M1, M2 to the respective two (redundant) controllers S1, again by means of a respective left L1, L2. S2 are connected, so that a failure of a controller S1, S2 does not affect the operation. In this case, the doors T1 and T3 of the first group G1 and the doors T2 and T4 of the second group G2 are assigned, so that adjacent platform screen door T1-T4 belong to different groups G1, G2.

Da ein Zugsegment (z.B. Waggon bzw. Abteil) eines Zuges gewöhnlich über zumindest zwei Zugtüren verfügt, ist auf diese Weise eine Aufrechterhaltung eines Normalbetriebes des Bahnsteigs - wenn auch mit verminderter Performance - möglich. Dabei kann durch die Nutzung der in Zügen natürlicherweise vorhandenen Redundanz (= mehrere Zugtüren je Segment) der erforderliche Mehraufwand auf ein Minimum reduziert werden, da nicht jede Bahnsteigtür T1-T9 redundant angesteuert werden muss und auch die in den Türen T1-T4 vorhandenen Aktoren nicht redundant ausgeführt werden müssen.Since a train segment (eg wagon or compartment) of a train usually has at least two train doors, is in this way a maintenance of normal operation of the platform - although with reduced performance - possible. It can be reduced to a minimum by using the inherent redundancy in trains (= multiple train doors per segment), since not every platform door T1-T9 must be controlled redundantly and not present in the doors T1-T4 actuators must be executed redundant.

FIG 3 zeigt ein weiteres Beispiel eines erfindungsgemäßen Türsystems, bei dem die beiden dargestellten Gruppen G1, G2 von Bahnsteigtüren T1-T4 über je ein Übertragungsmedium M1, M2 an jeweils nur eine Steuerung S1, S2 angeschlossen sind. Somit ist das Türsystem zwar nicht mehr immun gegen den Ausfall einer Steuerung S1, S2, allerdings können dafür die Links L1, L2 (z.B. Y-Koppler) zum Anschluss der Gruppen G1, G2 an jeweils mehrere Steuerungen S1, S2 eingespart werden. Ist jedoch die Ausfallwahrscheinlichkeit einer Steuerung S1, S2 geringer als die eines Links L1, L2, so tritt ein Ausfall einer ganzen Gruppe G1, G2 von Bahnsteigtüren T1-T4 im Ausführungsbeispiel dieser Figur trotz des einfacheren Aufbaus sogar seltener auf als in dem der Figur 2. FIG. 3 shows a further example of a door system according to the invention, in which the two illustrated groups G1, G2 of platform screen doors T1-T4 are each connected via a transmission medium M1, M2 to only one controller S1, S2. Thus, although the door system is no longer immune to the failure of a controller S1, S2, however, the links L1, L2 (eg, Y coupler) for connecting the groups G1, G2 to a plurality of controllers S1, S2 can be saved for this purpose. However, if the probability of failure of a controller S1, S2 is less than that of a left L1, L2, so occurs a failure of a whole group G1, G2 of platform doors T1-T4 in the embodiment of this figure, despite the simpler structure, even less than in that of FIG. 2 ,

Zusammenfassend betrifft die Erfindung ein Verfahren zum Steuern von Bahnsteigtüren, die in einem Abstand zueinander angeordnet sind, der dem von Zugtüren eines vom Bahnsteig zu betretenden Zuges entspricht, sowie ein Bahnsteigtürsystem. Um Bahnsteigtüren auf einfache Weise derart anzusteuern, dass das Türsystem eines Bahnsteigs hochverfügbar ist, wird vorgeschlagen, dass die Bahnsteigtüren in eine Anzahl von zumindest zwei Gruppen unterteilt werden, benachbarte Bahnsteigtüren verschiedenen Gruppen zugeordnet werden, jede Gruppe über je ein Übertragungsmedium mit zumindest zwei Steuerungen verbunden wird, Steuersignale von zumindest einer Steuerung über die Übertragungsmedien an die Bahnsteigtüren übermittelt werden und bei Ausfall einer Steuerung die Funktionen der ausgefallenen Steuerung der zumindest zweiten Steuerung übertragen werden.In summary, the invention relates to a method for controlling platform screen doors, which are arranged at a distance corresponding to that of train doors of a train to be entered from the platform, and a platform door system. In order to easily control platform screen doors such that the platform's door system is highly available, it is proposed that the platform screen doors be divided into a number of at least two groups, adjacent platform screen doors be assigned to different groups, each group connected to at least two controllers via one transmission medium each is transmitted control signals from at least one controller via the transmission media to the platform screen doors and in case of failure of a controller, the functions of the failed control of the at least second control are transmitted.
