Description

Method and device arrangement for the individual automated traffic guidance of road users at an airport

The invention relates to a method for the individual automated routing of road users at an airport. The invention further relates to a device arrangement for the individual automated routing of road users at an airport.

In the document "AMCP Working Group F Meeting - Use of Ground Marker Beacons to Reduce Runway Incursions", available on the Internet at http: //legacy.icao. int / anb / panels / acp / WG / F / WGF9 / WP / WGF917.doc, proposes a runway incident reduction system that outputs location-based voice messages to road users. For this purpose, so-called ground markers are distributed on the runway, which automatically emit a prepared voice message on a frequency of 75 MHz when an aircraft is detected. Since all instrument-flying aircraft have a receiver tuned to this frequency, the so-called "marker beacon receiver", the messages can in principle be heard in all aircraft located near the ground marker.

EP 1 234 293 A1 describes the technical details of such a system. The automatically sent voice messages are to inform the pilot whether he is moving on the right runway and whether he has taken the right direction. For the detection of the presence of an aircraft antenna cables are provided, which are embedded at certain points of the runway in the ground. The system can be extended by additionally providing data from in-aircraft systems, such as heading, ground speed, GPS position data, and aircraft type.

WO 2006/070207 A1 shows a further development of the known system, in which a central control unit of the ground marker system with is coupled to the standard at larger airports ground radar system (SMR). Once the radar system foresees a dangerous situation based on the current aircraft movements at the airport, a warning voice message corresponding to the respective hazard level is sent from a selection of prepared messages to 75 MHz, from the ground marker closest to the aircraft involved. Since all nearby aircraft receive the message, the pilots of these aircraft still have to decide for themselves whether the message is intended for them or not. The voice messages available for retrieval may be adapted to particular circumstances, e.g. B. to announce the closure of a runway or runway. For this purpose, new messages are received and kept ready by air traffic control.

The object of the invention is to improve the guidance of road users in an airport in order to avoid incidents and to enable a more efficient ground control.

This object is achieved by a method having the features of claim 1 and by a device arrangement having the features of claim 12. Advantageous and expedient embodiments of the method according to the invention and of the device arrangement according to the invention are specified in the associated subclaims.

The inventive method for the individual automated routing of road users at an airport comprises the following steps:

Providing position information of at least one road user; - providing traffic parameters concerning the traffic situation at the airport;

- Creating an individual route for the road user in a central management unit, including the position information and the traffic parameters; and signaling to the road user instructions relating to the individual route. Road users at an airport are primarily airplanes that move or park after landing or taking off at the airport. However, road users may also be vehicles used at the airport whose position can be determined externally or otherwise made available in real time. A route is to be understood here as a route to be specified, at least within a zone. The term "instructions" is intended to encompass not only guidance instructions but also warnings or other route related information, in particular those that are usually communicated to the road user by an air traffic controller.The instructions may also include: start sequence position, weather information and runway nature, A-CDM target times, required frequency changes due to change of responsibility of the ANSP / airport operator, orders for drivers, tow orders, clearances, etc.

The invention is based on the recognition that it is not possible at many airports due to the high density of intersections, junctions, etc., to guide a road user properly with a known from the prior art method without involvement of an air traffic controller. The sensory detection of road users by induction loops, photoelectric sensors or the like is far too expensive, and the full announcement of the many changes of direction could not be triggered quickly enough in succession. On the other hand, the method according to the invention makes it possible to automatically detect the position of a road user at any time, to create an optimum route for him and to inform him completely about it at once. In addition, a lot of other information can be conveyed automatically, which is not possible today due to the high workload of air traffic controllers.

The information about the position of the road users is preferably determined based at least on radar and / or multilateration. Most major airports have a ground radar system for airfield surveillance. Such radar systems automatically detect the position and movements of all road users. Modern Multilaterationssysteme not only provide position data (after appropriate evaluation of the one Signals sent by road users), but also further information that serves to identify a road user. By communicating with a database of the airport then hereby further information can be linked to the sensorially detected road users, such. B. the target of the rolling motion or loading data. Basically, one of the two systems will last as long as it covers the relevant areas, but preference is given to sensor data fusion based on both radar and multilateration systems.

If an automatically generated route is communicated to a particular road user, the corresponding instructions should include an identification of the road user. The explicit mention of the road user avoids that other nearby road users, who can also follow the instructions, feel wrongly addressed. According to the preferred embodiment of the invention, the instructions are transmitted in digital form from the central management unit via a data link to at least one local radio transmitter, and the radio transmitter sends individual voice messages corresponding to these instructions to the road user, preferably at a uniform frequency of 75 MHz. Since the instructions are initially transmitted only in digital form to the local radio transmitters, the amount of data to be transmitted is low. In accordance with the invention, it is intended to convey to the road user not only a single instruction but a reasonable plurality of instructions at a time as a voice message. This has a positive effect on the utilization of other speech radio frequencies.

Synthetic voice messages are automatically generated and sent from the instructions received from the central management unit only in the local radio transmitters. In this way, it is possible to produce tailor-made announcements for a road user, without the need for an air traffic controller to be switched on.

In a further development of the invention, it is provided that the instructions which are transmitted from the central guidance unit to the local radio transmitter installation include an indication that determines the transmission power for the voice message. This determines the range within which the voice message can be received. In special cases, if, for example, all road users in a certain area are to be addressed as quickly as possible, the appropriate transmission power can automatically be specified.

The instructions do not necessarily have to be communicated to the road user in the form of voice messages. Alternatively or additionally, the instructions can also be transmitted in digital form from the local radio transmitter to the road user and / or they can be signaled to the road user at least partially by visually perceptible information.

Thus, for the visual presentation of the instructions, a local taxiway center line lighting may be included, especially in an intersection area of the airport.

At least part of the visually perceptible information can also be displayed with the aid of dynamic light signals and / or dynamic signage and / or at least one traffic light.

It is also conceivable to signal the instructions on a display system of the traffic participant. In the case of an aircraft, this may be the so-called electronic flight bag or, in the case of a vehicle, a navigation display.

The invention also provides a device arrangement for the individual automated routing of road users at an airport. The device arrangement according to the invention comprises means for providing position information of at least one road user, means for providing traffic parameters concerning the traffic situation at the airport, and a central guidance unit for processing the position information and the traffic parameters. According to the invention, the central guidance unit is arranged so that it can create an individual route for the road user, taking into account the position information and the traffic parameters, and it is with the central guidance unit connected means for individual signaling of individual route instructions to the road user provided.

The central management unit of the device arrangement according to the invention is connectable to central units of other systems used at an airport, such. As disposition tools, tractor control, deicing control, etc., to facilitate the transmission of further information. As already mentioned, the instructions may also include sequence position at take-off, weather and runway condition information, A-CDM target times, required frequency changes due to changes of responsibility of the ANSP / airport operator, orders for drivers, towing contracts , Releases, etc.

With regard to further advantages of the device arrangement according to the invention and some embodiments, reference is made to the corresponding advantages of the method according to the invention. According to the preferred embodiment of the invention, the device arrangement comprises a local radio transmitter adapted to receive digital instructions from the central guidance device, to provide individual voice messages corresponding to the instructions and to send the individual voice messages to the road user, preferably at a uniform frequency of 75 MHz.

It makes sense to provide several distributed at the airport local radio transmitters. Preferably, at least some of the local radio transmitters are operable with variable transmission power. In principle, of course, all local radio transmitters can be operated with increased transmission power, but this would have a negative impact on the overall cost of the system.

Further features and advantages of the invention will become apparent from the following description of a particular embodiment of the invention. Reference is made to the accompanying drawing, in which the single figure shows a conceptual representation of the particular embodiment.

At an airport, using a ground radar system (SMR) and / or a multilateration system (MLAT) as part of a Sensor data fusion 10 determines the positions of road users 12. Additional detection systems can contribute to this, if available. In addition, a range of other information about a road user is provided, such as aircraft identification, flight number, arrival or departure (inbound / outbound), etc., as far as possible with existing systems.

The position information and the further information, if relevant, are made available to a guidance system 14 with a central guidance device. Furthermore, the central management facility is provided with up-to-date information about the traffic situation at the airport, such as traffic conditions, weather, driving conditions (smoothness, etc.), open or closed runways and taxiways, which are generally referred to as traffic parameters become. This information comes from established air traffic management systems, eg. As by a so-called arrival and departure manager and the like, with the help of forecasts can be created.

The central management facility is connected to workstations 16 of the air traffic controllers, so it can be operated and monitored by air traffic controllers or other authorized personnel. Physically, the central management unit is located in the tower 18 of the airport. In principle, however, it can also be arranged elsewhere ("remote tower") .The same applies to the connected workstations 16. The tower or the air traffic controllers should always also include the apron control.

Distributed over the runway 20 of the airport are several local radio transmitters 22 (ground markers), especially at critical points such as intersection areas. The radio transmitters 22 are wired or wirelessly connected to the central guidance device and adapted to broadcast voice messages at a uniform frequency of 75 MHz. This frequency is tuned to special receivers, the so-called "marker beacon receiver", which can be found in any instrument-flying aircraft. In addition, the local radio transmitters 22 have means for generating synthetic voice messages. However, the local radio transmitters 22 can also be used to transmit information not as voice messages, but in digital form to the road user. Such information can z. These include: D-Taxi (Datalink Taxi) clearances, layout information (airport maps such as AMMs), layers such as Ground Traffic Displays (GTDs), etc., or special instructions such as Single Engine Taxi (turning off an engine on the taxiway).

The position information and the traffic parameters are processed in the central management unit. Based on this processing, instructions for further behavior at the airport are automatically generated for a road user 12. More specifically, based on the position information and other traffic parameters, the central guidance unit creates an individual route for road user 12. This route may extend to a larger area, e.g. B. the optimal route in the given circumstances from the parking position to the intended runway or from the runway to the intended parking position, or only to a smaller area such as a zone with multiple intersections. The corresponding instructions are transmitted in digital form from the central management device to one, several selected or all local radio transmitters 22. In the radio transmitter (s) 22, synthetic voice messages corresponding to the digital instructions are automatically generated. The instructions contain, in particular, the identification of the addressed road user 12 and guidance instructions intended to guide the road user 12. These instructions go beyond simple commands such as "left" or "right". They contain a sequence of instructions that relate to the entire route created by the central management unit. As already mentioned, a route does not necessarily mean the entire route from a parking position to the runway or from a runway to the parking position, but may also only relate to a specific zone, for example a section with several intersections. In addition, the created route is usually a currently valid recommendation ("expected route"), which may change during the movement of the road user. For example, part of a voice message could be: "Lufthansa 400, turn left on Alpha 4." Each voice message is intended for one or only a few road users 12 who are preferably directly addressed and contains individual instructions next aircraft at the same place receive a different and specific for this Rollan event certain information, such as: "Speedbird 1502, hold Short of Alpha 4."

The voice messages may be heard by the road users 12 who are near the local radio transmitters 22 transmitting the voice message with their 75 MHz receivers. Due to the unique identification of the addressed road user 12 is immediately recognizable for the pilot or driver, whether the voice message is intended for him or not.

The route generation and voice message output are triggered primarily by the processing of the position information of the road users 12 obtained by means of the sensor data fusion and of the further traffic parameters in the central guidance unit. In principle, however, a triggering by a local detection of the road user 12 by means of sensors on the runway 20 is possible. Due to the inclusion of the further traffic parameters and the position information of other road users 12, conditional instructions can also be generated in the central guidance unit, which are then signaled to the road user 12 in the manner described above. For example, a release for pushback may be tied to a condition or other rolling motion, or a pilot is automatically told to follow a particular road user. For example, a voice message might read: "Lufthansa 390, taxi behind Aer Lingus A320 on Alpha, turn left on daddy 16."

In special cases, the central management unit may provide the instructions with a code which determines the transmission power with which the corresponding voice message is to be output from the radio transmitter (s) 22. This is z. For example, if all aircraft in a particular area should stop immediately. Prerequisite for this is that at least some of the local radio transmitters 22 can transmit with variable transmission power. These facilities are strategically placed on the runway 20.

Alternatively or in addition to the voice messages, the instructions may also be visually signaled to the road user 12, at least some of the instructions. This can be done in particular by appropriate control of a local taxiway center line firing, dynamic light signals, dynamic signage and / or at least one traffic light. A further supplement is the representation of instructions on a so-called electronic flight bag of an aircraft, on a separate display system in a vehicle or on an existing display (for example of a navigation device) of the road user 12.

Due to the initially described position detection, which is continuously continued, and the other traffic parameters that are always currently available, compliance with the given route can be monitored by the central management unit. Under certain conditions, eg. B. if an unexpected event is an obstacle to the previously created route, the route can be dynamically adjusted in the sequence and signaled to the road user 12 in accordance with adapted form.

Not only aircraft can be considered with the automatically generated individual instructions, but in principle any vehicle whose position information can be fed to the central management unit. To receive individual voice messages, however, a 75 MHz receiver in the vehicle is required.
