Description

L'invention porte sur un système et un procédé d'aide à l'identification et au contrôle d'aéronefs présents dans un secteur aérien à surveiller.The invention relates to a system and method for assisting the identification and control of aircraft present in an air sector to be monitored.

Le contrôle aérien est un ensemble de services rendus par les contrôleurs aériens aux aéronefs afin d'aider à l'exécution sûre, rapide et efficace des vols. Les services rendus sont au nombre de trois, appelés services de la navigation aérienne, dans les buts :

  • de prévenir des collisions entre les aéronefs et le sol ou les véhicules d'une part, et les collisions en vol entre aéronefs d'autre part (autrefois appelés "abordages"). Il consiste aussi à accélérer et ordonner la circulation aérienne ;
  • de fournir des avis et renseignements utiles à l'exécution sûre et efficace du vol : informations météorologiques, information sur l'état des moyens au sol de navigation, information sur le trafic (quand le service de contrôle n'est pas assuré dans cette zone) ; et
  • de fournir un service d'alerte pour prévenir les organismes appropriés lorsque les aéronefs ont besoin de l'aide des organismes de secours et de sauvetage, et de prêter à ces organismes le concours nécessaire.
Air traffic control is a set of services provided by air traffic controllers to aircraft to assist the safe, rapid and efficient performance of flights. The services rendered are three in number, called air navigation services, for the following purposes:
  • prevent collisions between aircraft and ground or vehicles on the one hand, and collisions between aircraft on the other (previously known as "collisions"). It also consists of speeding up and ordering air traffic;
  • to provide advice and information useful for the safe and efficient execution of the flight: meteorological information, information on the state of the ground means of navigation, information on the traffic (when the control service is not assured in this zone ); and
  • to provide an alert service to warn the appropriate agencies when the aircraft need help from rescue and rescue organizations, and to lend these bodies the necessary assistance.

Pour assurer ces services, un organisme (tour de contrôle, centre en route...) est mis en place. Il en existe plusieurs types. Suivant le type de trafic, différents organismes assurent le contrôle de la circulation aérienne.To provide these services, an organization (control tower, en-route center, etc.) is set up. There are several types. Depending on the type of traffic, different organizations provide air traffic control.

Les centres en route de la navigation aérienne CRNA sont chargés d'assurer les services de la circulation aérienne au bénéfice des aéronefs en croisière, hors de proximité d'aérodrome. Par exemple, il existe cinq centres de contrôles régionaux, également appelés centres en route, en France qui se répartissent la fourniture du service de contrôle sur tout le territoire français.The CRNA en-route airborne centers are responsible for providing air traffic services for aircraft cruising out of the vicinity of an aerodrome. For example, there are five regional control centers, also known as en route centers, in France that distribute control service throughout France.

Les centres de contrôle d'approche APP sont chargés d'assurer les services de la circulation aérienne aux abords d'un aérodrome, dans une zone de contrôle dont la taille est variable. Les contrôleurs aériens sont généralement situés dans la vigie d'une tour de contrôle, ou dans une salle radar spécialement aménagée.Approach control centers APP are responsible for providing air traffic services in the vicinity of an aerodrome, in a control zone of variable size. Air traffic controllers are usually located in the look-out of a control tower, or in a specially equipped radar room.

Les centres de contrôle d'aérodrome TWR sont chargés d'assurer les services de la circulation aérienne dans une zone restreinte, de l'ordre d'une dizaine de kilomètres, autour d'un aérodrome. Leur principale attribution est la gestion de la piste d'atterrissage. Le service est rendu depuis la vigie d'une tour de contrôle.The TWR aerodrome control centers are responsible for providing air traffic services in a restricted area of around ten kilometers around an aerodrome. Their main assignment is the management of the airstrip. The service is rendered from the lookout of a control tower.

Ces organismes ont été différenciés car les compétences requises, les règles applicables, et les moyens techniques nécessaires ne sont pas les mêmes. Un centre de contrôle en route nécessite un radar, tandis que l'outil principal en contrôle d'aérodrome est la vue. En approche, tous les avions veulent aller au même endroit : la piste, on a ainsi un phénomène "d'entonnoir". En route, les avions ont tous des provenances et destinations différentes, les problèmes sont donc pour beaucoup éparpillés et aléatoires. Ces différences, et d'autres, ont conduit a cette classification.These bodies have been differentiated because the skills required, the rules applicable, and the technical means required are not the same. An en route control center requires a radar, while the main tool in aerodrome control is the view. In approach, all the planes want to go to the same place: the track, one thus has a phenomenon of "funnel". En route, planes all have different origins and destinations, so the problems are for many scattered and random. These and other differences led to this classification.

Le trafic aérien augmentant sans cesse depuis ses débuts, la charge de travail et le nombre de tâches à effectuer des contrôleurs aériens augmentent en conséquence.Since air traffic has been increasing steadily since its inception, the workload and the number of tasks to be performed by air traffic controllers are increasing accordingly.

Il est connu la demande de brevet allemand DE 196 19 015 A1 qui divulgue un système d'aide à l'identification et au contrôle d'aéronefs à surveiller dans les environs d'un aéroport, avec des moyens de reconnaissance vocale pour analyser des communications des communications orales échangées entre un contrôleur aérien et les pilotes d'aéronefs présents dans les environs de l'aéroport. Un tel système est limité.It is known the German patent application DE 196 19 015 A1 which discloses a system for assisting the identification and control of aircraft to be monitored in the vicinity of an airport, with voice recognition means for analyzing communications of oral communications exchanged between an air traffic controller and the pilots of aircraft present in the vicinity of the airport. Such a system is limited.

L'invention vise à limiter la charge de travail des contrôleurs aériens, induite par la recherche visuelle d'un aéronef sur l'écran radar, ou la charge induite par la sélection d'informations concernant l'aéronef.The invention aims to limit the workload of air traffic controllers, induced by the visual search of an aircraft on the radar screen, or the load induced by the selection of information concerning the aircraft.

Il est proposé, selon un aspect de l'invention, un système d'aide à l'identification et au contrôle d'aéronefs présents dans un secteur aérien à surveiller, comprenant :

  • des moyens de reconnaissance vocale pour analyser des communications orales échangées entre le contrôleur aérien et les pilotes d'aéronefs présents dans ledit secteur aérien, et
  • des moyens de gestion adaptés pour effectuer une comparaison entre des données délivrées par lesdits moyens de reconnaissance vocale et des identifiants mémorisés représentatifs d'aéronefs respectifs prévus pour être présents dans ledit secteur aérien, les moyens de gestion étant, en outre, adaptés pour comparer des informations saisies par le contrôleur aérien avec des données délivrées par lesdits moyens de reconnaissance vocale traitant des instructions orales du contrôleur aérien aux pilotes d'aéronefs.
According to one aspect of the invention, there is provided a system for assisting the identification and control of aircraft present in an air sector to be monitored, comprising:
  • voice recognition means for analyzing oral communications exchanged between the air traffic controller and the aircraft pilots present in said air sector, and
  • management means adapted to perform a comparison between data delivered by said voice recognition means and stored identifiers representative of respective aircraft provided for be present in said air sector, the management means being further adapted to compare information entered by the air traffic controller with data provided by said voice recognition means processing oral instructions from the air controller to the aircraft pilots.

Un tel système permet de limiter la charge de travail du contrôleur aérien, en attirant l'attention du contrôleur aérien automatiquement sur le symbole représentant, à l'écran, l'aéronef avec lequel le contrôleur aérien est en cours de communication. Le couplage avec des identifiants prédéterminés permet de limiter drastiquement les erreurs de reconnaissance vocale dues aux bruits de transmissions.Such a system makes it possible to limit the workload of the air traffic controller by automatically drawing the attention of the air traffic controller to the symbol representing, on the screen, the aircraft with which the air traffic controller is communicating. The coupling with predetermined identifiers makes it possible to drastically limit voice recognition errors due to transmission noises.

Un tel système permet de vérifier les données entrées dans le système par le contrôleur aérien, de manière à limiter le risque d'erreur de saisie.Such a system makes it possible to check the data entered into the system by the air traffic controller, so as to limit the risk of an input error.

Dans un mode de réalisation, le système est muni de moyens d'affichage pour visualiser un espace comprenant ledit secteur aérien et des aéronefs présents dans ledit espace, et de moyens de visualisation sur lesdits moyens d'affichage d'un aéronef parmi l'ensemble des aéronefs présents, lesdits moyens de gestion étant adaptés pour commander dynamiquement lesdits moyens de visualisation pour mettre en évidence graphiquement l'aéronef dont le pilote échange des communications orales avec le contrôleur aérien à partir de données délivrées par lesdits moyens de reconnaissance vocale.In one embodiment, the system is provided with display means for displaying a space comprising said air sector and aircraft present in said space, and display means on said display means of an aircraft among the set aircraft present, said management means being adapted to dynamically control said display means to graphically highlight the aircraft whose pilot exchanges oral communications with the air controller from data delivered by said voice recognition means.

Il est ainsi possible pour le contrôleur aérien, de visualiser en temps réel, sur son écran d'affichage, l'aéronef du pilote avec lequel le contrôleur aérien est en cours de communication.It is thus possible for the air traffic controller to visualize in real time, on his display screen, the aircraft of the pilot with whom the air traffic controller is communicating.

Selon un mode de réalisation, lesdits moyens de gestion sont, en outre, adaptés pour coupler lesdites données délivrées par lesdits moyens de reconnaissance vocale avec un état de vol mémorisé des aéronefs affichés sur lesdits moyens d'affichage.According to one embodiment, said management means are further adapted to couple said data delivered by said voice recognition means with a stored flight status of the aircraft displayed on said display means.

On limite encore plus le risque d'erreurs de reconnaissance vocale dues aux bruits des transmissions.It further limits the risk of voice recognition errors due to transmission noise.

En outre, ou en variante, lesdits moyens de gestion sont adaptés pour coupler lesdites données délivrées par lesdits moyens de reconnaissance vocale avec au moins un paramètre de vol mémorisé des aéronefs affichés sur lesdits moyens d'affichage parmi l'altitude, la vitesse, le cap, la destination, au moins un point du plan de vol, l'altitude de croisière, la vitesse verticale, l'altitude de sortie du secteur aérien, le point de sortie du secteur aérien, et au moins un circuit d'attente actif.In addition, or alternatively, said management means are adapted to couple said data delivered by said voice recognition means with at least one stored flight parameter of the aircraft displayed on said display means among the altitude, the speed, the cap, the destination, at least one point of the flight plan, the cruising altitude, the vertical speed, the exit altitude of the air sector, the exit point of the air sector, and at least one active holding pattern .

Le risque d'erreurs de reconnaissance vocale dues aux bruits des transmissions peut ainsi être limité.The risk of voice recognition errors due to transmission noise can be limited.

Dans un mode de réalisation, lesdits moyens de gestion sont, en outre, adaptés pour saisir des informations directement à partir de données délivrées par lesdits moyens de reconnaissance vocale traitant des instructions orales du contrôleur aérien aux pilotes d'aéronefs.In one embodiment, said management means are further adapted to input information directly from data delivered by said voice recognition means processing oral instructions from the air controller to the aircraft pilots.

Il est ainsi possible d'envisager une reconnaissance vocale capable de reconnaître de nombreuses instructions ou données à prendre en considérations, prononcées par le contrôleur aérien, lorsque celle-ci est capable de bien filtrer les bruits de transmission.It is thus possible to envisage a voice recognition capable of recognizing numerous instructions or data to be taken into consideration, pronounced by the air traffic controller, when the latter is able to filter the transmission noise well.

Dans un mode de réalisation, lesdits moyens de gestion sont, en outre, adaptés pour proposer une sous-liste de valeurs parmi une liste de valeurs possibles pour un paramètre de vol d'un aéronef à partir de données délivrées par lesdits moyens de reconnaissance vocale traitant des instructions orales du contrôleur aérien aux pilotes d'aéronefs.In one embodiment, said management means are further adapted to propose a sub-list of values from a list of possible values for a flight parameter of an aircraft from data delivered by said voice recognition means. dealing with the air traffic controller's verbal instructions to pilots of aircraft.

Ainsi, le contrôleur peut gagner du temps, notamment lorsqu'il doit entrer une valeur d'un paramètre dans le système, et que la procédure d'entrée de cette valeur lui propose un menu déroulant comprenant un très grand nombre de valeurs prédéterminées possibles. En effet, le système peut ainsi directement ouvrir la liste de valeurs possibles et la positionner sur la plage de valeurs correspondant à l'instruction orale du contrôleur aérien.Thus, the controller can save time, especially when it must enter a value of a parameter in the system, and that the entry procedure of this value offers a drop-down menu comprising a very large number of possible predetermined values. Indeed, the system can thus directly open the list of possible values and position it on the range of values corresponding to the oral instruction of the air controller.

Selon un mode de réalisation, lesdits moyens de gestion sont adaptés pour commander dynamiquement lesdits moyens de visualisation pour visualiser un aéronef à partir de données délivrées par lesdits moyens de reconnaissance vocale traitant une demande orale du contrôleur aérien de visualisation d'un aéronef comprenant l'identifiant dudit aéronef.According to one embodiment, said management means are adapted to dynamically control said display means to visualize an aircraft from data delivered by said voice recognition means processing an oral request of the aerial visual controller of an aircraft comprising the identifier of said aircraft.

Ainsi, quand le contrôleur cherche un aéronef sur son écran, il peut le visualiser instantanément en prononçant son identifiant, comme pour une fonction de recherche mais dont l'activation saisie se ferait par reconnaissance vocale.Thus, when the controller looks for an aircraft on his screen, he can instantly view it by pronouncing his identifier, as for a search function but whose activation would be entered by voice recognition.

Selon un autre aspect de l'invention, il est également proposé un procédé d'aide à l'identification et au contrôle d'aéronefs présents dans un secteur aérien à surveiller caractérisé en ce qu'il comprend les étapes consistant à :

  • analyser par reconnaissance vocale des communications orales échangées entre le contrôleur aérien et les pilotes d'aéronefs présents dans ledit secteur aérien,
  • coupler des données délivrées par ladite reconnaissance vocale et des identifiants mémorisés représentatifs d'aéronefs respectifs prévus pour être présents dans ledit secteur aérien, et
  • comparer des informations saisies par le contrôleur aérien avec des données délivrées par lesdits moyens de reconnaissance vocale (RV) traitant des instructions orales du contrôleur aérien aux pilotes d'aéronefs.
According to another aspect of the invention, there is also provided a method for assisting the identification and control of aircraft present in an air sector to be monitored, characterized in that it comprises the steps of:
  • analyze by voice recognition the oral communications exchanged between the air traffic controller and the pilots of aircraft in the air sector,
  • coupling data delivered by said voice recognition and stored identifiers representative of respective aircraft intended to be present in said air sector, and
  • comparing information entered by the air traffic controller with data delivered by said voice recognition (VR) means processing oral instructions from the air traffic controller to the aircraft pilots.

Selon un mode de mise en ouvre, le procédé comprend, en outre, une étape consistant à visualiser l'aéronef dont le pilote échange des communications orales avec le contrôleur aérien, parmi lesdits aéronefs présents dans ledit secteur aérien.According to one embodiment, the method further comprises a step of visualizing the aircraft whose pilot exchanges oral communications with the air traffic controller, among said aircraft present in said air sector.

L'invention sera mieux comprise à l'étude de quelques modes de réalisation décrits à titre d'exemples nullement limitatifs et illustrés par les dessins annexés sur lesquels :

  • la figure 1 illustre schématiquement un poste de contrôle de la navigation aérienne d'aéronefs selon un aspect de l'invention ; et
  • la figure 2 illustre schématiquement un procédé de contrôle de la navigation aérienne d'aéronefs selon un aspect de l'invention.
The invention will be better understood by studying a few embodiments described by way of non-limiting examples and illustrated by the appended drawings in which:
  • the figure 1 schematically illustrates an air navigation control station of aircraft according to one aspect of the invention; and
  • the figure 2 schematically illustrates a method of controlling aircraft air navigation according to one aspect of the invention.

Sur la figure 1 est illustré un exemple d'un système de contrôle de la navigation aérienne d'aéronefs présents dans un secteur aérien à surveiller selon un aspect de l'invention. Une station de contrôle d'un contrôleur aérien est représentée avec un clavier CLA, une unité centrale UC et un écran d'affichage EA.On the figure 1 is illustrated an example of an air navigation control system for aircraft present in an air sector to be monitored according to one aspect of the invention. An air traffic controller control station is represented with a CLA keyboard, a CPU and an EA display screen.

Sur l'écran d'affichage EA, est affiché un espace aérien comprenant un secteur aérien SA à surveiller par le contrôleur aérien, comprenant sur cet exemple une première trajectoire possible T1, sur laquelle se trouvent deux aéronefs A1 et A2 ayant respectivement un identifiant ID1 et ID2 affichés, et une deuxième trajectoire possible T2, sur laquelle se trouvent deux aéronefs A3 et A4 ayant respectivement un identifiant ID3 et ID4 affichés.On the display screen EA is displayed an airspace comprising an air sector SA to be monitored by the air traffic controller, comprising in this example a first possible trajectory T1, on which are located two aircraft A1 and A2 respectively having an ID1 identifier and ID2 displayed, and a second possible trajectory T2, on which are two aircraft A3 and A4 respectively having ID3 ID4 and ID4 displayed.

Le système comprend un module de reconnaissance vocale RV muni d'un micro MIC, pour analyser des communications orales échangées entre le contrôleur aérien et les pilotes d'aéronefs présents dans ledit secteur aérien.The system includes a voice recognition module RV equipped with a microphone MIC, to analyze oral communications exchanged between the air controller and the aircraft pilots present in said air sector.

Le système comprend également un module de gestion GES adapté pour effectuer une comparaison entre des données délivrées par lesdits moyens de reconnaissance vocale RV et des identifiants mémorisés LID représentatifs d'aéronefs respectifs prévus pour être présents dans le secteur aérien SA. Ainsi, une liste LID d'identifiants des aéronefs devant traverser le secteur aérien SA est comparée aux identifiants reconnus par le module de reconnaissance vocale RV, par le module de gestion GES. Ceci permet de limiter drastiquement le risque d'erreur de reconnaissance par le module de reconnaissance vocale RV.The system also includes a GES management module adapted to perform a comparison between data delivered by said RV voice recognition means and LID stored identifiers representative of respective aircraft intended to be present in the air sector SA. Thus, an LID list of identifiers of the aircraft to cross the airline sector SA is compared to the identifiers recognized by the voice recognition module RV, by the management module GES. This makes it possible to drastically limit the risk of recognition error by the voice recognition module RV.

Le système peut également comprendre, un état des vols mémorisé EDV, des avions affichés sur l'écran d'affichage EA, par exemple un aéronef a un état de vol assumé, lorsqu'il est dans le secteur aérien SA à surveiller par le contrôleur, et un état de vol transféré, lorsqu'il est affiché à l'écran d'affichage EA, mais transféré à un autre secteur aérien à surveiller par un autre contrôleur aérien.The system may also include, a stored flight status EDV, aircraft displayed on the EA display screen, for example an aircraft has an assumed flight status, when in the air sector SA to be monitored by the controller , and a transferred flight status, when displayed on the EA display screen, but transferred to another air sector to be monitored by another air controller.

Un module de visualisation VIS permet de visualiser sur l'écran d'affichage EA un aéronef, par exemple en l'affichant d'une couleur différente de l'affichage des autres aéronefs. Le module de gestion GES est adapté pour commander dynamiquement les moyens de visualisation VIS pour visualiser l'aéronef dont le pilote échange des communications orales avec le contrôleur aérien à partir de données délivrées par le module de reconnaissance vocale RV. Ainsi, en temps réel, le contrôleur aérien peut visualiser à l'écran l'aéronef avec lequel il échange des communications.A visualization module VIS makes it possible to display on the display screen EA an aircraft, for example by displaying it in a different color from the display of the other aircraft. The GES management module is adapted to dynamically control the visualization means VIS to visualize the aircraft whose pilot exchanges oral communications with the air traffic controller from data delivered by the voice recognition module RV. Thus, in real time, the air traffic controller can view on the screen the aircraft with which he exchanges communications.

Le module de gestion GES peut, par exemple, servir à saisir directement des informations à partir de données délivrées par lesdits moyens de reconnaissance vocale RV traitant des instructions orales du contrôleur aérien, lorsque le taux d'erreur de la reconnaissance vocale RV est très faible.The management module GES can, for example, be used to directly enter information from data delivered by said voice recognition means RV processing oral instructions of the air controller, when the error rate of voice recognition RV is very low .

Le module de gestion GES peut, par exemple, comparer des informations enregistrées par le contrôleur aérien à partir de données délivrées par lesdits moyens de reconnaissance vocale RV traitant des instructions orales du contrôleur aérien. Ainsi, le module de gestion peut comparer des données tapées au clavier CLA par le contrôleur aérien, et les données qu'il a prononcées, et ainsi détecter d'éventuelles fautes de frappe au clavier CLA, et détecter de possibles erreurs.The GES management module can, for example, compare information recorded by the air traffic controller from data delivered by said voice recognition means RV dealing with the oral instructions of the air traffic controller. Thus, the management module can compare data typed CLA keyboard by the air controller, and the data he has spoken, and thus detect possible keyboard typing errors CLA, and detect possible errors.

Le module de gestion GES peut, par exemple, proposer une sous-liste de valeurs parmi une liste de valeurs possibles pour un paramètre de vol d'un aéronef à partir de données délivrées par les moyens de reconnaissance vocale RV traitant des instructions orales du contrôleur aérien. Ainsi, le contrôleur peut gagner du temps, notamment lorsqu'il doit entrer une valeur d'un paramètre dans le système, et que la procédure d'entrée de cette valeur lui propose un menu déroulant comprenant un très grand nombre de valeurs prédéterminées possibles. Le système affiche alors directement la plage de valeurs concernées.The GES management module may, for example, propose a sub-list of values from a list of possible values for an aircraft flight parameter from data delivered by the voice recognition means RV processing the controller's verbal instructions. air. Thus, the controller can save time, especially when it must enter a value of a parameter in the system, and that the entry procedure of this value offers a drop-down menu comprising a very large number of possible predetermined values. The system then directly displays the relevant range of values.

Le module de gestion GES peut commander dynamiquement le module de visualisation VIS pour visualiser un aéronef à partir de données délivrées par lesdits moyens de reconnaissance vocale RV sur une demande orale du contrôleur aérien pour visualiser un aéronef en prononçant l'identifiant de l'aéronef.The GES management module can dynamically control the visualization module VIS to visualize an aircraft from data delivered by said voice recognition means RV on an oral request from the air traffic controller to visualize an aircraft by pronouncing the identifier of the aircraft.

Sur la figure 2 est illustré un procédé selon un aspect de l'invention.On the figure 2 is illustrated a method according to one aspect of the invention.

Les communications orales échangées entre le contrôleur aérien et les pilotes des aéronefs présents dans le secteur aérien à surveiller SA, sont traités par reconnaissance vocale dans une étape 1, par le module de reconnaissance vocale RV.The oral communications exchanged between the air traffic controller and the pilots of the aircraft present in the air sector to be monitored SA, are processed by voice recognition in a step 1, by the voice recognition module RV.

Puis un couplage avec une liste d'identifiants LI D et optionnellement avec un état des vols mémorisés EDV est fait dans une étape 2, pour limiter drastiquement les erreurs de reconnaissance.Then a coupling with a list of identifiers LI D and optionally with a state of the flights stored EDV is done in a step 2, to drastically limit the recognition errors.

D'autres couplages sont possibles, par exemple avec l'altitude, et/ou le cap, et/ou la vitesse, et/ou la phase de vol. En effet, si un aéronef est en phase de montée, et que son altitude est de 17000 ft, si le contrôleur donne une nouvelle altitude, celle-ci sera forcément supérieure a 17000 ft. Ainsi, ce couplage permet de réduire le champ d'investigation de la reconnaissance vocale : l'analyse sur l'ordre doit produire une valeur supérieure à 17000 ft.Other couplings are possible, for example with the altitude, and / or the heading, and / or the speed, and / or the flight phase. Indeed, if an aircraft is climbing, and its altitude is 17000 ft, if the controller gives a new altitude, it will necessarily be higher than 17000 ft. Thus, this coupling makes it possible to reduce the field of investigation of the voice recognition: the analysis on the command must produce a value greater than 17000 ft.

Le résultat est affiché sur l'écran d'affichage EA lors d'une troisième étape.The result is displayed on the EA display screen in a third step.

La présente invention permet d'améliorer les conditions de travail d'un contrôleur aérien, et limite ses possibilités d'erreurs.The present invention makes it possible to improve the working conditions of an air traffic controller, and limits its possibilities of errors.
