Verfahren und Vorrichtung zur Einrichtung einer Umleitung im Falle einer Blockierung eines Fahrweges in einem Überwa- chungsbereich Method and device for establishing a detour in the event of a blockage of a route in a monitoring area

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Einrichtung einer Umleitung im Falle einer Blockierung eines Fahrweges in einem Überwachungsbuch, 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 diversion in the event of a blockage of a route in a monitoring book, 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 AI 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 lo- kalisierenden Objekt von einem Server der Leitstelle desDE 10 2007 029 131 A1 discloses a method and a system for improving the accuracy in the position determination of a movable object to be located on an airport apron. 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, the object to be localized by a server of the control center of

und/oder A-GPS-Daten. Die auf diese Weise ermittelten korrigierten Positionsdaten werden an den der Leitstelle zugehöri- gen Server des Flughafens übertragen. and / or A-GPS data. The corrected position data determined in this way are transmitted to the server belonging to the control center of the airport.

Mittels des vorstehend beschriebenen bekannten Verfahrens können auf Basis der erfolgten GPS-Positionsermittlung Bewegungen von Fahrzeugen auf dem Flughafenvorfeld verfolgt wer- den. Diese Fahrzeugbewegungen finden innerhalb zugelassener Bereiche statt. Die Einhaltung dieser Bereiche wird von der Leitstelle überwacht. Verlässt das jeweilige Fahrzeug die zu- gelassenen 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. If the respective vehicle leaves the left 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. 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. Die Aufgabe der Erfindung besteht darin, ein Einrichten von Umfahrungen eines blockierten Fahrweges zu vereinfachen. 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 route location in the control system maps of the control center and adjusting 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. 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. The object of the invention is to simplify the establishment of bypasses of a blocked track.

Diese Aufgabe wird durch ein Verfahren mit den im Anspruch 1 angegebenen Merkmalen und durch eine Vorrichtung mit den im Anspruch 6 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. This object is achieved by a method having the features specified in claim 1 and by a device having the features specified in claim 6. Advantageous embodiments and further developments of the invention are specified in the dependent claims.

Ein Vorteil der Erfindung besteht darin, dass die Umfahrung des blockierten Fahrweges automatisch eingerichtet wird, sobald der Leitstelle das Vorliegen des blockierten Fahrweges bekannt ist. Ein Eintragen einer Umfahrung für die blockierte Stelle in eine in der Leitstelle vorliegende Karte durch eine berechtigte Person ist nicht notwendig. Ebenso wenig bedarf es einer Vorausdefinition von möglichen Umfahrungen für jeden Abschnitt der Fahrwege beispielsweise eines Flughafenvorfeldes . An advantage of the invention is that the bypassing of the blocked route is automatically established as soon as the control center is aware of the presence of the blocked route. Entering a detour for the blocked position into a card present in the control center by means of a authorized person is not necessary. Nor does it require a pre-definition of possible detours for each section of the routes, for example, an airport apron.

Ein weiterer Vorteil der Erfindung besteht darin, dass auch der Leitstelle nicht bekannte Gegebenheiten bei der Einrichtung der Umfahrung des blockierten Streckenabschnitts berücksichtigt werden können, beispielsweise auf oder neben dem Fahrweg abgestellte Gegenstände. A further advantage of the invention is that circumstances which are not known to the control center can also be taken into account when setting up the bypassing of the blocked section of the route, for example items parked on or next to the track.

Weitere vorteilhafte Eigenschaften der Erfindung ergeben sich aus deren nachfolgender beispielhafter Erläuterung anhand der Figuren. Es zeigt: Further advantageous features of the invention will become apparent from the following exemplary explanation with reference to FIGS. It shows:

FIG 1 eine Skizze, die die zum Verständnis der Erfindung notwendigen Bestandteile einer Vorrichtung zur Einrichtung einer Umleitung im Falle einer Blockierung eines Fahrweges auf einem Flughafenvorfeld enthält, 1 shows a sketch which contains the components necessary for understanding the invention of a device for establishing a diversion in the event of a blockage of a roadway on an airport apron,

FIG 2 ein Flussdiagramm zur Erläuterung eines Verfahrens zur Einrichtung einer Umleitung im Falle einer Blockierung eines Fahrweges auf einem Flughafenvorfeld. 2 shows a flowchart for explaining a method for establishing a diversion in the event of a blockage of a roadway on an airport apron.

Die in der Figur 1 dargestellte Vorrichtung weist eine Leit- stelle 61, einen der Leitstelle zugehörigen Rechner 11 und eine der Leitstelle 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 und dem Fahrzeug 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 empfan- genen, von den GPS-Satelliten 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 AI beschrieben ist. The device shown in FIG. 1 has a control station 61, a computer 11 associated with the control station and a communication device 12 belonging to the control center. 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 configured to bidirectionally transmit radio signals between the control center and the vehicle 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 gene, radiated from the GPS satellites signals position data describing the current position of the vehicle 1. To increase the accuracy of this position data, the computer 22 may use correction data, as described in DE 10 2007 029 131 AI.

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 mo- mentanen 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, with reference to the vehicle 1 shown in FIG. 1, further data are stored which entitle the vehicle 1 to use a specific route on the airport apron in a certain period of time.

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 über die Funkübertragungsstrecke 12-23 vom Fahrzeug an die Leitstelle übertragen. In der Leitstelle wird mittels des dort vorgesehenen Rechners 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 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 dar- über, dass und an welcher Stelle der Fahrweg blockiert ist. During the travel of the vehicle 1 on this route, position data of the vehicle moving on the travel path are transmitted from the vehicle to the control center 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 is checked by means of the computer provided there continuously, whether the vehicle 1 actually moves on the released for the vehicle 1 track. If the vehicle 1 leaves this route, this is detected by the computer 11 of the control center and an alarm is triggered. If the route on which the vehicle 1 is currently moving is blocked, for example due to a breakdown of a vehicle in front, then the driver of the vehicle 1 informs the control center, for example by means of a radiotelephone, that and at which point the route is blocked.

Die Leitstelle 11 ermächtigt daraufhin das Fahrzeug 1 zu einer Umfahrung des blockierten Fahrweges . Aufgrund dieser Er- mächtigung 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 Leit- stelle 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 21 bzw. deren Rechner 11 übertragen. The control center 11 then authorizes the vehicle 1 to bypass the blocked track. Because of this authorization, the driver of the vehicle 1, taking into account the local environment of the blocked route itself make a detour of the blocked route. It can also leave the blocked route without the control center initiating the triggering of an alarm. During this bypassing of the blocked driving path, the position determining device 21, 22 of the vehicle 1 repeatedly ascertains position data of the vehicle 1 bypassing the blocked travel path and transmits it to the control center 21 or its computer 11 via the radio transmission path 12-23.

Der Rechner 11 der Leitstelle 61 ermittelt aus diesen Positionsdaten die Umfahrungstrecke beschreibende Daten und speichert diese in einem der Leitstelle 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.

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, welchen weiteren Fahrzeugen die Erlaubnis erteilt wurde, den nunmehr blockierten Fahrweg zu benutzen, und überträgt diese Erlaubnisdaten auf die Umfahrungsstrecke . Subsequently, the computer 11 of the control center 61 checks on the basis of already stored further data which is permission data valid for the blocked route, which other vehicles have been given permission to use the now blocked route, and transmits this permission data to the bypass route.

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

Aufgrund dieser Übertragung der Erlaubnisdaten auf die Umfah- rungsstrecke können alle Fahrzeuge, denen diese Erlaubnis zu- geteilt wurde, den Umfahrungsweg nutzen, ohne dass von der Leitstelle ein Alarm ausgelöst wird. Due to this transfer of the permit data to the detour route, all vehicles to which this permission has been assigned 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 11 über die Beendigung der Blockade infor- miert. Als Reaktion darauf hebt die Leitstelle die oben beschriebene Übertragung der Erlaubnisdaten auf die Umfahrungs- strecke wieder auf, so dass der Zustand vor dem Eintreten der Blockierung wieder hergestellt wird. Wie vorstehend beschrieben wurde erfolgt beim Gegenstand der vorliegenden Erfindung das Einrichten einer Umleitung und das Aufheben derselben automatisch dann, wenn der Leitstelle die 5 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 zur Umfahrung des blockierten Fahrweges berechtiget) ten Fahrzeug während des Umfahrens des blockierten Fahrweges zur Verfügung gestellt werden. If the said blockage of the travel path has ended, the control center 11 is informed about the termination of the blockage. In response, the control center rescales the above-described transmission of the permission data to the bypass route, so that the state is restored before the blocking occurs. As described above, in the subject matter of the present invention, the establishment of a diversion and the cancellation of the same occur automatically when the control center has the information about the presence of a blocked roadway or the information about the suspension of the blockage of the roadway. The diversion is established by using position data provided by a vehicle authorized by the control center 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 in vor- 15 teilhafter Weise lokale Gegebenheiten berücksichtigen, die der Leitstelle nicht bekannt sind, beispielsweise neben dem Fahrweg abgestellte Gegenstände. During this bypassing of the blocked driving path, the driver of the vehicle driving around the blocked driving path can take account of local conditions which are not known to the control center, for example objects parked next to the driving way.

Die Figur 2 zeigt ein Flussdiagramm zur Erläuterung eines 20 Verfahrens zur Einrichtung einer Umleitung im Falle einer FIG. 2 shows a flowchart for explaining a method for establishing a diversion in the case of a

Blockierung eines Fahrzeuges auf einem Flughafenvorfeld.  Blocking a vehicle on an airport apron.

Dieses Verfahren geht davon aus, dass der Leitstelle 61 bereits bekannt ist, welcher Fahrweg des Flughafenvorfeldes 25 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 25 is blocked and at which point of the route this blockage occurs.

Sobald die Leitstelle Kenntnis der genannten Blockierung erhalten hat, ermächtigt sie in einem Schritt Sl ein nachfol- 30 gendes Fahrzeug zur Umfahrung des blockierten Fahrweges . Über diese Ermächtigung wird der Fahrer des Fahrzeugs informiert. Er hat dann die Möglichkeit, den blockierten Fahrweg zu verlassen, um die blockierte Stelle des Fahrweges zu umfahren, ohne dass in der Leitstelle ein Alarm ausgelöst wird. As soon as the control center has become aware of the said blockage, it authorizes in a step Sl a following vehicle to bypass the blocked track. This authorization informs the driver of the vehicle. 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.

Während dieser Umfahrung der blockierten Stelle des Fahrzeugs erfolgt in einem Schritt S2 eine wiederholte Ermittlung von Positionsdaten des ermächtigten, den blockierten Fahrweg um- fahrenden Fahrzeugs mittels der Positionsbestimmungsvorrichtung 21,22 des Fahrzeugs. During this bypassing of the blocked position of the vehicle, in a step S2 a repeated determination of position data of the authorized, blocked roadway takes place. moving vehicle by means of the position determining 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. Sind diese Daten der Umfahrungsstrecke ermittelt, dann werden diese in einem Schritt S4 in einem der Leitstelle 61 zugehörigen Spei- eher IIa 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. If these data of the detour route are determined, these are stored in a step S4 in a store IIa belonging to the control center 61.

Danach erfolgt in einem Schritt S5 seitens der Leitstelle 61 ein Übertragen von für den blockierten Fahrweg geltenden, im Speicher IIa abgespeicherten und weiteren Fahrzeugen zugeord- neten Erlaubnisdaten auf die Umfahrungsstrecke . Aufgrund der Übertragung dieser Erlaubnisdaten können auch die genannten weiteren Fahrzeuge die vorgegebene Umfahrungsstrecke benutzen, ohne dass in der Leitstelle ein Alarm ausgelöst wird bzw. ohne dass von der Leitstelle sonstige Gegenmaßnahmen er- griffen werden. Thereafter, in a step S5 on the part of the control center 61, a transmission of permission data, which is valid for the blocked travel path and stored in the memory IIa and assigned to further 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 or without any other countermeasures being taken by the control center.

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

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.
