Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Einrichtung einer Umleitung im Falle einer Blockierung eines Fahrweges in einem Überwachungsbereich, insbesondere auf einem Flughafenvorfeld. Es werden selbstlenkende Fahrzeuge auf einer Oberfläche umgeleitet, insbesondere Straßenfahrzeuge.The invention relates to a method and a device for establishing a detour in the event of a blockage of a route in a surveillance area, in particular on an airport apron. It will redirect self-steering vehicles on a surface, especially road vehicles.

Aus der DE 10 2007 029 131 A1 sind ein Verfahren und ein System zur Genauigkeitsverbesserung bei der Positionsermittlung eines auf einem Flughafenvorfeld zu lokalisierenden beweglichen Objektes bekannt. Das zu lokalisierende Objekt, bei dem es sich beispielsweise um einen Bus, einen Tankwagen oder ein Catering-Fahrzeug handelt, weist einen GPS-Empfänger, einen Rechner und eine Einrichtung zur drahtlosen Kommunikation auf. Die Positionsermittlung des zu lokalisierenden Objektes erfolgt im zu lokalisierenden Objekt unter Verwendung des dort vorhandenen GPS-Empfängers und des dort vorhandenen Rechners, wobei zur Erhöhung der Genauigkeit der Positionsermittlung Zusatzinformationen verwendet werden, die dem zu lokalisierenden Objekt von einem Server der Leitstelle des Flughafens übermittelt werden. Bei diesen Zusatzinformationen handelt es sich um EGNOS-Signale, DGPS-Korrekturdaten und/ oder A-GPS-Daten. Die auf diese Weise ermittelten korrigierten Positionsdaten werden an den der Leitstelle zugehörigen Server des Flughafens übertragen.From the DE 10 2007 029 131 A1 For example, a method and a system for improving accuracy in the position determination of a movable object to be located on an airport apron are known. The object to be located, which is for example a bus, a tanker or a catering vehicle, has a GPS receiver, a computer and a device for wireless communication. The position determination of the object to be located takes place in the object to be localized using the existing there GPS receiver and there existing computer, to increase the accuracy of the position determination additional information is used, which is transmitted to the object to be located by a server of the control center of the airport , This additional information is EGNOS signals, DGPS correction data and / or A-GPS data. The corrected position data determined in this way are transmitted to the airport's server associated with the control center.

Mittels des vorstehend beschriebenen bekannten Verfahrens können auf Basis der erfolgten GPS-Positionsermittlung Bewegungen von Fahrzeugen auf dem Flughafenvorfeld verfolgt werden. Diese Fahrzeugbewegungen finden innerhalb zugelassener Bereiche statt. Die Einhaltung dieser Bereiche wird von der Leitstelle überwacht. Verlässt das jeweilige Fahrzeug die zugelassenen Bereiche, dann wird eine geeignete Gegenmaßnahme ergriffen, beispielsweise ein Alarm ausgelöst.By means of the known method described above, movements of vehicles on the airport apron can be tracked on the basis of the completed GPS position determination. These vehicle movements take place within approved areas. Compliance with these areas is monitored by the control center. Leaves the respective vehicle the approved Areas, then a suitable countermeasure is taken, for example, an alarm triggered.

Ist ein zugelassener Fahrweg blockiert, beispielsweise durch einen Unfall oder ein liegengebliebenes Fahrzeug, dann müssen andere Fahrzeuge, die diesen Fahrweg benutzen wollen, die blockierte Stelle des Fahrweges temporär umfahren können, ohne dass ein Alarm ausgelöst wird. Dazu muss die genannte Blockierung des Fahrweges der Leitstelle bekanntgemacht werden. Ist dies geschehen, dann werden in der Leitstelle händisch durch eine berechtigte Person Änderungen vorgenommen. Diese bestehen darin, in den in der Leitstelle vorliegenden Karten eines Überwachungssystems eine Umfahrung für die blockierte Stelle des Fahrweges einzutragen und die Berechtigungen für diesen Bereich anzupassen. Alternativ dazu können für jeden Abschnitt der Fahrwege auf dem Flughafenvorfeld mögliche Umfahrungen im Voraus definiert und in die Karten des Überwachungssystems eingetragen werden.If an approved route blocked, for example, by an accident or a broken-down vehicle, then other vehicles that want to use this track, the blocked point of the route can temporarily bypass without an alarm is triggered. For this purpose, the said blockage of the route of the control center must be made known. If this has happened, changes are made manually in the control center by an authorized person. These consist of entering a bypass for the blocked position of the track in the maps of a monitoring system available in the control center and adapting the authorizations for this area. Alternatively, for each section of the routes on the airport apron, possible detours can be defined in advance and entered into the maps of the monitoring system.

Ist die Blockierung des genannten Fahrweges beendet, dann muss dies wiederum der Leitstelle bekannt gemacht werden, so dass in der Leitstelle alle vorgenommenen Änderungen wieder rückgängig gemacht werden können.If the blockage of said route is completed, then this in turn must be made known to the control center, so that in the control center all changes made can be undone.

Aus der WO 03/044 632 A2 ist ein Verfahren zur Überwachung eines von einem Fahrzeug gefahrenen Weges bekannt. Im Rahmen dieses Verfahrens kann das Fahrzeug durch eine Leitstelle ermächtigt werden, einen vorbestimmten Fahrweg zu verlassen.

Die in der Figur 1 dargestellte Vorrichtung weist eine Leitstelle 61, einen der Leitstelle 61 zugehörigen Rechner 11 und eine der Leitstelle 61 zugehörige Kommunikationsvorrichtung 12 auf. Des Weiteren enthält die dargestellte Vorrichtung ein Fahrzeug 1, welches mit einer Positionsbestimmungsvorrichtung ausgestattet ist. Zu dieser Positionsbestimmungsvorrichtung gehören beim gezeigten Ausführungsbeispiel ein GPS-Empfänger 21 und ein Rechner 22. Der Rechner 22 ist mit einer Kommunikationsvorrichtung 23 verbunden. Die Kommunikationsvorrichtungen 12 und 23 sind vorzugsweise Funkübertragungsvorrichtungen, die zur bidirektionalen Übertragung von Funksignalen zwischen der Leitstelle 61 und dem Fahrzeug 1 über den Übertragungsweg 12-23 ausgebildet sind. Der GPS-Empfänger 21 ist zum Empfang von Signalen vorgesehen, die von GPS-Satelliten 25 ausgestrahlt werden. Der Rechner 22 ermittelt aus den empfangenen, von den GPS-Satelliten 25 ausgestrahlten Signalen Positionsdaten, die die momentane Position des Fahrzeugs 1 beschreiben. Zur Erhöhung der Genauigkeit dieser Positionsdaten kann der Rechner 22 Korrekturdaten verwenden, wie es in der DE 10 2007 029 131 A1 beschrieben ist.The in the FIG. 1 The device shown has a control station 61, a control center 61 associated computer 11 and the control center 61 associated communication device 12. Furthermore, the illustrated device includes a vehicle 1, which is equipped with a position-determining device. In the embodiment shown, a GPS receiver 21 and a computer 22 belong to this position determination device. The computer 22 is connected to a communication device 23. The communication devices 12 and 23 are preferably radio transmission devices which are designed for the bidirectional transmission of radio signals between the control center 61 and the vehicle 1 via the transmission path 12-23. The GPS receiver 21 is provided for receiving signals emitted from GPS satellites 25. The computer 22 determines from the received signals emitted by the GPS satellites 25 position data which describe the instantaneous position of the vehicle 1. To increase the accuracy of this positional data, the computer 22 may use correction data as shown in the DE 10 2007 029 131 A1 is described.

Auf dem Flughafenvorfeld gibt es eine Vielzahl von Fahrwegen, auf denen sich berechtigte Fahrzeuge bewegen. Jedes dieser Fahrzeuge ist von der Leitstelle 61 registriert in dem Sinne, dass im Rechner 11 der Leitstelle bzw. einem dort vorgesehenen Speicher Daten abgespeichert sind, die den Kennungen der einzelnen Fahrzeuge entsprechen, wobei zu jeder Kennung Daten abgespeichert sind, die der momentanen Position des jeweiligen Fahrzeugs entsprechen, sowie weitere Daten, die den momentanen Einsatz des Fahrzeugs charakterisieren. So sind beispielsweise bezüglich des in der Figur 1 gezeigten Fahrzeugs 1 weitere Daten abgespeichert, die das Fahrzeug 1 dazu berechtigen, in einem bestimmten Zeitraum einen bestimmten Fahrweg auf dem Flughafenvorfeld zu benutzen.On the airport apron, there are a variety of routes on which eligible vehicles move. Each of these vehicles is registered by the control center 61 in the sense that data are stored in the computer 11 of the control center or a memory provided there, which correspond to the identifiers of the individual vehicles, wherein for each identifier data is stored, the current position of the corresponding vehicle, as well as other data characterizing the current use of the vehicle. For example, in terms of in the FIG. 1 1 further data stored, which entitle the vehicle 1 to use in a certain period of time a certain route on the airport apron.

Während der Fahrt des Fahrzeugs 1 auf diesem Fahrweg werden von der Positionsbestimmungsvorrichtung 21,22 des Fahrzeugs 1 in vorgegebenen Zeitabständen Positionsdaten des sich auf dem Fahrweg bewegenden Fahrzeugs 1 über die Funkübertragungsstrecke 12-23 vom Fahrzeug 1 an die Leitstelle 61 übertragen. In der Leitstelle 61 wird mittels des dort vorgesehenen Rechners 11 laufend überprüft, ob sich das Fahrzeug 1 tatsächlich auf dem für das Fahrzeug 1 freigegebenen Fahrweg bewegt. Verlässt das Fahrzeug 1 diesen Fahrweg, dann wird dies vom Rechner 11 der Leitstelle 61 erkannt, und es wird ein Alarm ausgelöst. Ist der Fahrweg, auf dem sich das Fahrzeug 1 momentan bewegt, beispielsweise aufgrund einer Panne eines vorausfahrenden Fahrzeugs blockiert, dann informiert der Fahrer des Fahrzeugs 1 beispielsweise mittels eines Funktelefons die Leitstelle 61 darüber, dass und an welcher Stelle der Fahrweg blockiert ist.During the travel of the vehicle 1 on this route, position data of the vehicle 1 moving on the travel path are transmitted from the vehicle 1 to the control center 61 via the radio transmission path 12-23 at predetermined time intervals by the position determination device 21, 22 of the vehicle 1. In the control center 61 is continuously checked by means of there provided computer 11, whether the vehicle 1 actually moves on the released for the vehicle 1 track. If the vehicle 1 leaves this route, then this is detected by the computer 11 of the control center 61, and an alarm is triggered. If the travel path on which the vehicle 1 is currently moving is blocked, for example, due to a breakdown of a preceding vehicle, then the driver of the vehicle 1 informs the control center 61, for example by means of a radiotelephone, that the route is blocked and at which point.

Die Leitstelle 61 ermächtigt daraufhin das Fahrzeug 1 zu einer Umfahrung des blockierten Fahrweges. Aufgrund dieser Ermächtigung kann der Fahrer des Fahrzeugs 1 unter Beachtung der lokalen Umgebung des blockierten Fahrweges selbst eine Umfahrung des blockierten Fahrweges vornehmen. Er kann dabei auch den blockierten Fahrweg verlassen, ohne dass die Leitstelle 61 die Auslösung eines Alarms in die Wege leitet. Während dieser Umfahrung des blockierten Fahrweges werden von der Positionsbestimmungsvorrichtung 21,22 des Fahrzeugs 1 wiederholt Positionsdaten des den blockierten Fahrweg umfahrenden Fahrzeugs 1 ermittelt und über die Funkübertragungsstrecke 12-23 an die Leitstelle 61 bzw. deren Rechner 11
übertragen.The control center 61 then authorizes the vehicle 1 to bypass the blocked track. On the basis of this authorization, the driver of the vehicle 1 can undertake a bypass of the blocked route himself, taking into account the local environment of the blocked track. He can also leave the blocked route without the control center 61 initiating the triggering of an alarm in the way. During this bypassing of the blocked route, the position determining device is used 21,22 of the vehicle 1 repeatedly determines position data of the vehicle 1 bypassing the blocked route and via the radio transmission path 12-23 to the control center 61 or its computer 11
transfer.

Der Rechner 11 der Leitstelle 61 ermittelt aus diesen Positionsdaten die Umfahrungstrecke beschreibende Daten und speichert diese in einem der Leitstelle 61 zugehörigen Speicher ab.The computer 11 of the control center 61 determines data describing the bypass route from these position data and stores it in a memory associated with the control center 61.

Anschließend überprüft der Rechner 11 der Leitstelle 61 anhand bereits abgespeicherter weiterer Daten, bei denen es sich um für den blockierten Fahrweg geltende Erlaubnisdaten handelt, mit welchen weiteren Fahrzeugen die Erlaubnis erteilt wurde, den nunmehr blockierten Fahrweg zu benutzen, und überträgt diese Erlaubnisdaten auf die Umfahrungsstrecke.Subsequently, the computer 11 checks the control center 61 on the basis of already stored further data, which is permission data valid for the blocked route, with which other vehicles were granted permission to use the now blocked route, and transmits this permission data to the bypass route ,

Ist dies geschehen, dann informiert die Leitstelle 61 alle betroffenen Fahrzeuge über das Vorliegen des blockierten Fahrweges und über die neue Berechtigung des jeweiligen Fahrzeugs, den Umfahrungsweg benutzen zu dürfen.If this has happened, the control center 61 informs all affected vehicles about the presence of the blocked route and about the new authorization of the respective vehicle to use the bypass route.

Aufgrund dieser Übertragung der Erlaubnisdaten auf die Umfahrungsstrecke können alle Fahrzeuge, denen diese Erlaubnis zugeteilt wurde, den Umfahrungsweg nutzen, ohne dass von der Leitstelle ein Alarm ausgelöst wird.Due to this transfer of the permission data to the detour route, all vehicles to which this permission has been allocated can use the detour path without an alarm being triggered by the control center.

Ist die genannte Blockierung des Fahrweges beendet, dann wird die Leitstelle 61 über die Beendigung der Blockade informiert. Als Reaktion darauf hebt die Leitstelle 61 die oben beschriebene Übertragung der Erlaubnisdaten auf die Umfahrungsstrecke wieder auf, so dass der Zustand vor dem Eintreten der Blockierung wieder hergestellt wird.If the said blockage of the route is completed, then the control center 61 is informed of the termination of the blockage. In response, the control center 61 cancels the above-described transmission of the permission data to the bypass route again, so that the state is restored before the occurrence of the blockage.

Wie vorstehend beschrieben wurde, erfolgt beim Gegenstand der vorliegenden Erfindung das Einrichten einer Umleitung und das Aufheben derselben automatisch dann, wenn der Leitstelle 61 die Information über das Vorliegen eines blockierten Fahrweges bzw. die Information über die Aufhebung der Blockierung des Fahrweges vorliegt. Das Einrichten der Umleitung erfolgt unter Verwendung von Positionsdaten, die von einem von der Leitstelle 61 zur Umfahrung des blockierten Fahrweges berechtigten Fahrzeug 1 während des Umfahrens des blockierten Fahrweges zur Verfügung gestellt werden.As described above, in the subject matter of the present invention, the establishment of a diversion and the cancellation of the same takes place automatically when the control center 61 the Information about the presence of a blocked route or the information about the suspension of the blockage of the route is present. The diversion is set up using position data provided by a vehicle 1 authorized by the control center 61 to bypass the blocked route during the bypassing of the blocked route.

Bei dieser Umfahrung des blockierten Fahrweges kann der Fahrer des den blockierten Fahrweg umfahrenden Fahrzeugs 1 in vorteilhafter Weise lokale Gegebenheiten berücksichtigen, die der Leitstelle 61 nicht bekannt sind, beispielsweise neben dem Fahrweg abgestellte Gegenstände.In this bypassing of the blocked roadway, the driver of the vehicle 1 bypassing the blocked roadway can advantageously take into account local conditions which are not known to the control center 61, for example objects placed next to the roadway.

Die Figur 2 zeigt ein Flussdiagramm zur Erläuterung eines Verfahrens zur Einrichtung einer Umleitung im Falle einer Blockierung eines Fahrzeuges 1 auf einem Flughafenvorfeld.The FIG. 2 shows a flowchart for explaining a method for establishing a diversion in the event of a blockage of a vehicle 1 on an airport apron.

Dieses Verfahren geht davon aus, dass der Leitstelle 61 bereits bekannt ist, welcher Fahrweg des Flughafenvorfeldes blockiert ist und an welcher Stelle des Fahrweges diese Blockierung auftritt.This method assumes that the control center 61 is already aware of which route of the airport apron is blocked and at which point of the route this blockage occurs.

Sobald die Leitstelle 61 Kenntnis der genannten Blockierung erhalten hat, ermächtigt sie in einem Schritt S1 ein nachfolgendes Fahrzeug 1 zur Umfahrung des blockierten Fahrweges. Über diese Ermächtigung wird der Fahrer des Fahrzeugs 1 informiert. Er hat dann die Möglichkeit, den blockierten Fahrweg zu verlassen, um die blockierte Stelle des Fahrweges zu umfahren, ohne dass in der Leitstelle 61 ein Alarm ausgelöst wird.As soon as the control center 61 has become aware of the aforementioned blockage, it authorizes in a step S1 a subsequent vehicle 1 to bypass the blocked track. This authorization informs the driver of the vehicle 1. He then has the opportunity to leave the blocked track to bypass the blocked point of the route without an alarm is triggered in the control center 61.

Während dieser Umfahrung der blockierten Stelle des Fahrweges erfolgt in einem Schritt S2 eine wiederholte Ermittlung von Positionsdaten des ermächtigten, den blockierten Fahrweg umfahrenden Fahrzeugs 1 mittels der Positionsbestimmungsvorrichtung 21,22 des Fahrzeugs.During this bypassing of the blocked position of the travel path, a repeated determination of position data of the authorized vehicle 1 bypassing the blocked travel path takes place in a step S2 by means of the position determination device 21, 22 of the vehicle.

Anschließend erfolgt in einem Schritt S3 eine Ermittlung der Daten der Umfahrungsstrecke aus den ermittelten Positionsdaten mittels des Rechners 22 der Positionsbestimmungsvorrichtung oder mittels des Rechners 11 der Leitstelle 61. Sind diese Daten der Umfahrungsstrecke ermittelt, dann werden diese in einem Schritt S4 in einem der Leitstelle 61 zugehörigen Speicher 11a abgespeichert.Subsequently, in a step S3, a determination of the data of the detour route from the determined position data by means of the computer 22 of the position determining device or by means of the computer 11 of the control center 61. If these data of the detour route determined, then they are in a step S4 in one of the control center 61st associated memory 11a stored.

Danach erfolgt in einem Schritt S5 seitens der Leitstelle 61 ein Übertragen von für den blockierten Fahrweg geltenden, im Speicher 11a abgespeicherten und weiteren Fahrzeugen zugeordneten Erlaubnisdaten auf die Umfahrungsstrecke. Aufgrund der Übertragung dieser Erlaubnisdaten können auch die genannten weiteren Fahrzeuge die vorgegebene Umfahrungsstrecke benutzen, ohne dass in der Leitstelle 61 ein Alarm ausgelöst wird bzw. ohne dass von der Leitstelle 61 sonstige Gegenmaßnahmen ergriffen werden.Thereafter, in a step S5 on the part of the control center 61, a transmission of permission data for the blocked route, stored in the memory 11a and associated with other vehicles, is transmitted to the detour route. Due to the transmission of these permission data, the other vehicles mentioned can also use the predetermined detour route without an alarm being triggered in the control center 61 or without any other countermeasures being taken by the control center 61.

Ist die Blockierung des Fahrweges beendet, dann wird von der Leitstelle 61 die genannte Übertragung der Erlaubnisdaten auf die Umfahrungsstrecke rückgängig gemacht.If the blocking of the route is completed, then the transfer of the permission data to the detour route is reversed by the control center 61.

Vorstehend wurden ein Verfahren und eine Vorrichtung zur Einrichtung einer Umleitung im Falle einer Blockierung eines Fahrweges auf einem Flughafenvorfeld beschrieben. Alternativ dazu kann das beschriebene Verfahren und die beschriebene Vorrichtung auch zur Einrichtung einer Umleitung im Falle einer Blockierung eines Fahrweges in einem anderen Überwachungsbereich verwendet werden, beispielsweise in einem Hafenbereich oder in einer Chemieanlage.The foregoing has described a method and apparatus for establishing a detour in the event of an approach block on an airport apron. Alternatively, the method described and the device described can also be used for establishing a diversion in the event of a blockage of a route in another monitoring area, for example in a harbor area or in a chemical plant.
