Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Stillstandsüberwachung bei Schienenfahrzeugen mit einer Zugbeeinflussungseinrichtung.The invention relates to a method and a device for standstill monitoring in rail vehicles with a train control device.

Moderne Zugbeeinflussungseinrichtungen benötigen genaue Weg- bzw. Ortsinformationen sowohl abgestellter als auch fahrender Schienenfahrzeuge. Die US-Patentanmeldung US 2005/0137760 A1 offenbart dazu ein entsprechendes Verfahren.Modern train control devices require accurate location information of both parked and moving rail vehicles. The US patent application US 2005/0137760 A1 discloses a corresponding method.

Bisher ist es jedoch nicht möglich, festzustellen, ob bei ausgeschalteter Zugbeeinflussungseinrichtung der bei diesem Betriebszustand vorausgesetzte Stillstand des Schienenfahrzeugs tatsächlich eingehalten wurde. Werden Schienenfahrzeuge zum Betriebsende an Parkpositionen komplett ausgeschaltet, geht für die Zugbeeinflussung die genaue sicherungstechnische Zugposition verloren. Nach dem Wiedereinschalten des Schienenfahrzeuges ist die sicherungstechnische Position des Fahrzeuges nicht bekannt und die Initialisierung der Zugposition kann erst durch das Überfahren von mindestens zwei Ortsreferenzpunkten, z. B. Balisen, ermittelt werden. Erst danach kann das Fahrzeug aus Zugbeeinflussungssicht in Betrieb genommen werden. Das bedeutet, dass Fahrzeuge in Parkpositionen nicht komplett ausgeschaltet werden dürfen; zumindest die Zugbeeinflussung muss aktiv bleiben. Nachteilig ist vor allem der dazu erforderliche erhebliche Energiebedarf.So far, however, it is not possible to determine whether the standstill of the rail vehicle assumed in this operating state has actually been observed when the train control device is switched off. If rail vehicles are completely switched off at the end of operation at parking positions, the exact safety-related traction position is lost for the train control. After restarting the rail vehicle, the safety-technical position of the vehicle is not known and the initialization of the train position can only by passing over at least two location reference points, z. B. balises are determined. Only then can the vehicle be put into operation from the train control viewpoint. This means that vehicles in parking positions may not be switched off completely; at least the train control must remain active. The disadvantage is above all the required considerable energy consumption.

Eine andere Möglichkeit besteht darin, dass das Schienenfahrzeug seine sicherungstechnische Position vor dem Abschalten abspeichert und diese Position nach dem Wiedereinschalten als Initialisierungsposition verwendet wird. Notwendige sicherungstechnische Voraussetzung für die Verwendbarkeit der gespeicherten Fahrzeugposition ist, dass das Fahrzeug bei ausgeschalteter Zugbeeinflussung nicht bewegt wurden - Cold Movement. Erfolgt dennoch eine Bewegung des Schienenfahrzeuges, muss die Verwendung der ursprünglichen Position für Initialisierungszwecke durch Personal verhindert werden. Diese nicht technische Lösung ist in der Realität oft nicht umsetzbar.Another possibility is that the rail vehicle stores its fuse-technical position before switching off and this position is used after restarting as initialization position. Necessary securing technical prerequisite for the usability of the stored vehicle position is that the vehicle were not moved with train control disabled - Cold Movement. If, nevertheless, a movement of the rail vehicle takes place, the use of the original position for initialization purposes by personnel must be prevented. This non-technical solution is often not feasible in reality.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Stillstandsüberwachung bei Schienenfahrzeugen, welche über eine Zugbeeinflussungseinrichtung verfügen, anzugeben.The invention is therefore an object of the invention to provide a method and apparatus for standstill monitoring in rail vehicles, which have a train control device to specify.

Verfahrensgemäß wird die Aufgabe durch die Merkmale des Anpruches gelöst. Das Schienenfahrzeug speichert vor dem Abschalten der Zugbeeinflussungseinrichtung auf einer Parkposition seine sicherungstechnische Position ab. Zusätzlich zur Position werden Sensorinformationen einer Gleisfreimeldeeinrichtung der relevanten Gleisfreimeldeabschnitte abgespeichert. Nach dem Wiedereinschalten des Fahrzeuges werden die aktuellen Sensorinformationen von der Gleisfreimeldeeinrichtung abgefragt und entweder manuell oder automatisch mit den gespeicherten Sensorinformationen verglichen. Wenn diese exakt gleich sind, ist in den betreffenden Gleisfreimeldeabschnitten während des Ausschaltzustandes keine Zugbewegung - Cold Movement - erfolgt und die gespeicherte Zugposition kann sicherungstechnisch verwendet werden. Das Schienenfahrzeug ist bereits vor der Abfahrt, d. h., noch im Stillstand, signaltechnisch sicher lokalisiert bzw. initialisiert.According to the method, the object is achieved by the features of the Anpruches. Before switching off the train control device, the rail vehicle stores its safety-related position in a parking position. In addition to the position, sensor information of a track-free reporting device of the relevant track-free reporting sections is stored. After the vehicle is switched on again, the current sensor information is queried by the track-free reporting device and compared either manually or automatically with the stored sensor information. If these are exactly the same, no train movement - Cold Movement - takes place in the track free reporting sections during the switch-off state and the stored train position can be used for safety purposes. The rail vehicle is already before departure, d. h., still at a standstill, safely localized or initialized.

Auf diese Weise wird die gespeicherte Zugposition durch ein zusätzliches Kriterium sicherungstechnisch bewertet. Damit steht eine technische Lösung zur Verfügung, durch die der gespeicherte Fahrzeugort sicherungstechnisch plausibelisiert werden kann, so dass Personaleinsatz zur Gewährleistung der Sicherheit nicht erforderlich ist.In this way, the stored train position is evaluated by an additional criterion fuse technology. In order to There is a technical solution available, by means of which the stored vehicle location can be plausibly plausible, so that personnel deployment to ensure safety is not required.

Für die Stillstandsüberwachung bei ausgeschalteter Zugbeeinflussungseinrichtung ist durch die Funktionsausweitung der überwiegend bereits vorhandenen Komponenten, wie Gleisfreimeldeeinrichtungen und Speicher, kein eigenständiges Gerät auf dem Schienenfahrzeug erforderlich. Dadurch ergeben sich Kosten- und Einbauplatzvorteile, welche insbesondere für nachträglichen Einbau in Schienenfahrzeuge wichtig ist. Lediglich für die Speicherung und Auswertung der Sensorinformationen der Gleisfreimeldeeinrichtung muss gesorgt werden.For standstill monitoring when the train control device is switched off, the autonomous device on the rail vehicle is not required due to the expansion of functions of the predominantly existing components, such as track free alarm devices and storage. This results in cost and installation space advantages, which is particularly important for retrofitting in rail vehicles. Only the storage and evaluation of the sensor information of the track-free signaling device must be taken care of.

Gemäß der Erfindung umfassen die zu speichernden Sensorinformationen einen aktuellen Zählerstand von Achszählsensoren. Gleisfreimeldeabschnitte auf der Basis von Achszählsensoren sind weit verbreitet. Gespeichert werden muss nur der absolute Zählerstand unabhängig von der Fahrtrichtung.According to the invention, the sensor information to be stored comprises a current counter reading of axle counting sensors. Track free reporting sections based on axle counting sensors are widely used. Only the absolute meter reading must be stored regardless of the direction of travel.

Diese Information wird erfindungsgemäß über ein fahrzeugseitiges Streckengerät an das Schienenfahrzeug übertragen und gespeichert. Insbesondere für einen effizienten ETCS - European Train Control System - Level 2-Betrieb ist es erforderlich, dass das ETCS-Fahrzeuggerät feststellen kann, ob das Schienenfahrzeug seit dem Ausschalten der Zugbeeinflussungseinrichtung bewegt wurde. Dafür bestehen sehr hohe Anforderungen an das Sicherheitsniveau. Ohne Stillstandsüberwachung muss das Schienenfahrzeug nach dem Einschalten der Zugbeeinflussungseinrichtung zunächst in Fahrerverantwortung fahren, bis aufgrund von Baliseninformationen eine eindeutige Lokalisierung des Schienenfahrzeuges möglich ist und damit die Voraussetzung für den ETCS-Level 2-Betrieb gegeben ist. Eine sichere Betriebsweise, d. h., eine Minimierung der Fahrerverantwortung, ist erst durch die erfindungsgemäße Stillstandsüberwachung möglich. Der Zählerstand der Achszählsensoren wird direkt an Speichermittel des Schienenfahrzeuges kommuniziert. Dazu kann beispielsweise ein einfaches Funksystem verwendet werden.This information is transferred according to the invention via a vehicle-side distance device to the rail vehicle and stored. In particular, for an efficient European Train Control System (ETCS) level 2 operation, it is necessary for the ETCS on-vehicle unit to determine whether the rail vehicle has been moved since the train control device was switched off. There are very high demands on the security level. Without standstill monitoring, the rail vehicle must first drive in driver responsibility after switching on the train control device, until due to balise information a clear localization of the rail vehicle is possible and thus the condition for the ETCS level 2 operation is given. A safe mode of operation, ie a minimization of driver responsibility, is only possible by the standstill monitoring according to the invention. The meter reading of the axle counting sensors is communicated directly to storage means of the rail vehicle. For this purpose, for example, a simple radio system can be used.

Durch die erfindungsgemäße Lösung erhöht sich die Performance für das Initialisieren von Schienenfahrzeugen in Parkposition, beispielsweise in einen Fahrzeugdepot, da das Schienenfahrzeug nach dem Einschalten im Stillstand lokalisiert ist und sofort in den voll überwachten Betrieb übernommen werden kann. Im Stillstand kann das geparkte Schienenfahrzeug komplett ausgeschaltet werden, so dass der Energiebedarf sinkt und trotzdem nach dem Wiedereinschalten ein sofortiger voll überwachter Betrieb möglich ist.The solution according to the invention increases the performance for initializing rail vehicles in parking position, for example in a vehicle depot, since the rail vehicle is located at standstill after being switched on and can be taken over immediately into fully monitored operation. At standstill, the parked rail vehicle can be completely switched off, so that the energy requirement decreases and still an immediate fully monitored operation is possible after restarting.
