Description

DISPOSITIF DE SURVEILLANCE D'UN OBJET SENSIBLE TEL QU'UN AERONEF ET PROCEDE DE CONDUITE DE CE DISPOSITIF DEVICE FOR MONITORING A SENSITIVE OBJECT SUCH AS AN AIRCRAFT AND METHOD OF CONDUCTING IT
La présente invention concerne un dispositif de surveillance d'un objet sensible tel qu'un aéronef, plus particulièrement un avion d'affaires.The present invention relates to a device for monitoring a sensitive object such as an aircraft, more particularly a business jet.
L'invention couvre aussi le procédé de conduite de ce dispositif.The invention also covers the method of driving this device.
Il apparaît que certains véhicules terrestres comme les voitures de très haut de gamme, maritimes comme les yachts de luxe ou aériens comme les avions d'affaires ou les hélicoptères sont de plus en plus soumis à des contraintes de sécurité pour les protéger contre des actes de vandalisme, de négligence voire de terrorisme. Le vandalisme se traduit des manières les plus diverses, on peut citer à titre d'exemples : vol de kérosène, dégradations mécaniques, vol de pièces, ou encore l'apposition de tags.It appears that some land vehicles such as high-end, maritime cars such as luxury or airy yachts such as business jets or helicopters are increasingly subject to security constraints to protect them against acts of vandalism, negligence and even terrorism. Vandalism manifests itself in a variety of ways, for example: theft of kerosene, mechanical damage, theft of coins, or the affixing of tags.
Dans certains cas, les dégradations en elles-mêmes sont superficielles mais nécessitent des réparations qui sont, elles, d'un coût très élevé.In some cases, the degradations themselves are superficial but require repairs which are, they, a very high cost.
De plus, les propriétaires ou utilisateurs sont souvent des personnes exposées à des risques d'attentats ou pour le moins à des velléités d'agressions de la part de tiers, et ce type de véhicule peut devenir une cible privilégiée.In addition, the owners or users are often people exposed to the risk of attacks or at least to attacks of aggression from third parties, and this type of vehicle may become a preferred target.
De fait, il existe une demande en terme de surveillance de ces véhicules, surveillance qui doit être sophistiquée en terme de possibilités mais néanmoins d'une grande fiabilité compte tenu des véhicules sur lesquels ils doivent être installés.In fact, there is a demand in terms of surveillance of these vehicles, monitoring which must be sophisticated in terms of possibilities but nevertheless of high reliability given the vehicles on which they must be installed.
La description qui suit sera effectuée pour l'application à un aéronef tel qu'un avion d'affaires de sorte à situer avec acuité les contraintes qui se posent et à faire apparaître la qualité des solutions apportées par la présente invention, mais cette application n'est aucunement limitative et pourra être envisagée à tout autre type d'aéronef tel un hélicoptère par exemple.The following description will be made for the application to an aircraft such as a business jet so as to locate the constraints and the quality of the solutions provided by the present invention, but this application is in no way limiting and may be considered for any other type of aircraft such as a helicopter for example.
Dans le cas d'un avion ou d'un hélicoptère, le prix d'achat étant de plusieurs millions d'euros, la surveillance doit nécessairement être performante et ne pas interférer avec le fonctionnement de l'avion ou de l'hélicoptère lui-même dont l'agencement est complexe, soumis à des normes aussi draconiennes que nombreuses ainsi qu'à des agréments.In the case of an airplane or helicopter, the purchase price being several million euros, the surveillance must necessarily be efficient and not interfere with the operation of the plane or the helicopter itself. even the layout is complex, subject to standards as draconian as many and amenities.
Selon des enquêtes menées dans le domaine, il est constaté que de tels avions sont dans l'ensemble peu utilisés en comparaison avec les avions de ligne si bien qu'ils peuvent rester immobilisés pendant de longues périodes.According to investigations in the field, it is found that such aircraft are in general little used in comparison with the airliners so that they can remain immobilized for long periods.
Les infrastructures aéroportuaires sur lesquelles ils sont immobilisés, situés dans tous les pays du monde sont pour la plupart peu ou pas surveillés, souvent de petites dimensions donc facilement accessibles et également peu fréquentés.The airport infrastructures on which they are immobilized, located in all the countries of the world are for the most part little or not monitored, often of small dimensions thus easily accessible and also little frequented.
La solution recherchée est évidemment une solution autonome qui évite le maintien en permanence d'une présence humaine et vise une application de surveillance à distance.The solution sought is obviously an autonomous solution that avoids the permanent maintenance of a human presence and aims a remote monitoring application.
Cette situation engendre un grand nombre de problèmes qui vont maintenant être exposés sans que l'ordre de présentation ait un rapport avec l'intensité de la problématique.This situation generates a large number of problems that will now be exposed without the order of presentation being related to the intensity of the problem.
Il faut pouvoir surveiller l'avion 24h/24h et ceci pendant plusieurs jours d'affilée, jusqu'à une semaine pour donner un ordre d'idée. Il se pose donc un problème d'autonomie car un tel dispositif de surveillance doit être indépendant de sorte à ne pas perturber l'installation électrique de l'avion.It is necessary to be able to watch the plane 24h / 24h and this for several days in a row, until a week to give an order of idea. There is therefore a problem of autonomy because such a monitoring device must be independent so as not to disturb the electrical installation of the aircraft.
De plus, il ne suffit pas de déclencher une alarme en cas de pénétration d'un individu dans l'aéronef par une des ouvertures ou de toute autre effraction mais bien de surveiller c'est-à-dire de capter des images de l'environnement de l'avion. A ces moyens de capture des images, il est impératif d'associer des moyens de visualisation, de transmission de ces images et d'enregistrement de ces images.Moreover, it is not enough to trigger an alarm if an individual enters the aircraft through an opening or any other break-in but to monitor, that is to say to capture images of the environment of the aircraft. To these means of capturing images, it is imperative to associate means for viewing, transmitting these images and recording these images.
Un autre objectif de l'invention est de transmettre ces images au moyen d'un réseau téléphonique vers un appareil portable tel qu'un téléphone portable, dont dispose le propriétaire ou la personne de confiance en charge notamment de la surveillance. Une bonne gestion de la consommation intervient là aussi et oblige à retenir une solution la moins gourmande possible en énergie. Quant aux images, l'application exige que le champ couvert soit de 360°, non pas avec un secteur et un balayage de façon rotative mais de 360° simultanément de sorte à prévenir des intrusions venant de plusieurs directions au même moment. Quant à la distance de détection et de capture d'images, il faut prévoir une zone circulaire avec un rayon jusqu'à 50 mètres autour de l'avion pour donner un ordre d'idées. Comme un champ de caméra avec une distorsion acceptable à une telle distance couvre un angle maximum de 100°, il faut de fait quatre caméras, ce qui là aussi engendre une multiplication de la consommation électrique unitaire et donc porte préjudice à l'autonomie.Another object of the invention is to transmit these images by means of a telephone network to a portable device such as a mobile phone, which is available to the owner or the person of confidence in charge in particular of surveillance. Good consumption management also comes into play and forces us to choose the least energy-efficient solution possible. As for the images, the application requires that the covered field be 360 °, not with a sector and a sweeping rotationally but 360 ° simultaneously so as to prevent intrusions from several directions at the same time. As for the distance of detection and capture of images, it is necessary to provide a circular zone with a radius up to 50 meters around the plane to give an order of ideas. Since a camera field with an acceptable distortion at such a distance covers a maximum angle of 100 °, four cameras are needed, which also leads to a multiplication of the unit power consumption and thus to the loss of autonomy.
Un dispositif de surveillance se situe de façon préférentielle sous le fuselage de sorte à couvrir au sol, à hauteur d'homme sensiblement, notamment les trains d'atterrissage qui restent une partie très sensible, fortement exposée lorsque l'avion est au sol, autorisant également un accès à certaines parties du fuselage. Un tel dispositif étant rapporté sous le fuselage de l'avion, il faut tenir compte du fait qu'il doit être en position centrale, bien souvent au droit des réservoirs d'où la nécessité de prévoir une désolidarisation en cas de crash. Néanmoins, le boîtier doit permettre de résister aux températures extrêmes, aux forts écarts de température, au givre et à l'abrasion.A monitoring device is preferably located under the fuselage so as to cover the ground, at man's height substantially, including the landing gear which remains a very sensitive part, strongly exposed when the aircraft is on the ground, allowing also access to certain parts of the fuselage. Such a device being reported under the fuselage of the aircraft, it must be taken into account that it must be in the central position, often to the right of the tanks hence the need to provide a separation in case of a crash. Nevertheless, the housing must be able to withstand extreme temperatures, high temperature differences, frost and abrasion.
Un tel dispositif pose aussi des problèmes importants sur la détection en elle- même puisque c'est elle qui assure la première étape de la surveillance. Il faut donc atteindre une haute fiabilité de déclenchement avec d'une part une sensibilité assurant la détection pour chaque intrusion réelle mais qui, d'autre part, évite les alarmes intempestives.Such a device also poses significant problems on the detection itself since it is it which ensures the first stage of the surveillance. It is therefore necessary to achieve a high reliability of tripping with on the one hand a sensibility ensuring the detection for each real intrusion but which, on the other hand, avoids the nuisance alarms.
A cet effet, on a pu recourir dans des agencements antérieurs à une détection avec des moyens fonctionnant avec des détecteurs de rayonnements infrarouges.For this purpose, it has been possible to use in arrangements prior to detection with means operating with infrared radiation detectors.
Un tel choix est délicat car ce type de détecteur ne permet pas de générer un signal riche conduisant par traitement à une forte discrimination.Such a choice is difficult because this type of detector does not generate a rich signal leading treatment to a strong discrimination.
De plus, les perturbations des capteurs sont nombreuses du fait des fortes températures régnant sur certains terrains.In addition, the disturbances of the sensors are numerous because of the high temperatures prevailing on certain grounds.
Les détecteurs eux-mêmes nécessitent une infrastructure particulière et sophistiquée de guidage et de convergence des rayonnements pour permettre au capteur de travailler dans des conditions satisfaisantes.The detectors themselves require a particular and sophisticated radiation guiding and convergence infrastructure to enable the sensor to work in satisfactory conditions.
Enfin, les capteurs doivent être protégés contre les agressions mécaniques et contre l'abrasion. Ces protections, généralement des verres, doivent être transparents aux rayonnements infrarouges. Mais il faut alors conjuguer des caractéristiques antinomiques. Ainsi, les matériaux qui sont transparents aux rayonnements infrarouges présentent de faibles résistances mécaniques et/ou de faibles résistances aux fortes variations de températures.Finally, the sensors must be protected against mechanical aggression and against abrasion. These protections, usually glasses, must be transparent to infrared radiation. But then it is necessary to combine antinomic characteristics. Thus, materials that are transparent to infrared radiation have low mechanical strengths and / or low resistance to large temperature variations.
Certains matériaux, pouvant présenter une conjugaison acceptable des ces paramètres, sont d'un coût rédhibitoire, même pour des applications à des avions.Certain materials, which may have an acceptable conjugation of these parameters, are prohibitively costly, even for aircraft applications.
La présente invention propose un dispositif permettant de pallier les problèmes qui viennent d'être exposés, particulièrement applicable aux aéronefs, qui peut être mis en place sur les aéronefs neufs au cours de l'assemblage mais aussi sur les aéronefs en service, donc a posteriori.The present invention proposes a device to overcome the problems that have just been exposed, particularly applicable to aircraft, which can be implemented on new aircraft during assembly but also on aircraft in service, so a posteriori .
L'invention est décrite en détail suivant un mode de réalisation préférentiel, non limitatif, cette description s'appuyant sur les dessins annexés dont les différentes figures montrent de façon schématique : - figure 1 : une vue schématique d'un aéronef avec le positionnement du dispositif selon la présente invention,The invention is described in detail according to a preferred embodiment, not limiting, this description based on the accompanying drawings, the different figures show schematically: FIG. 1: a schematic view of an aircraft with the positioning of the device according to the present invention,
- figure 2 : une vue schématique du dispositif vu en élévation latérale,FIG. 2: a schematic view of the device seen in side elevation,
- figure 3 : une vue schématique de dessous du dispositif.- Figure 3: a schematic view from below of the device.
La description qui va suivre décrit un mode de réalisation considéré au moment du dépôt comme le meilleur mode de réalisation cette description prévoit un agencement avec une seule entité dite "POD" rapportée de façon fixe sous le fuselage de l'aéronef. Toujours selon cet agencement, un calculateur ainsi qu'une alimentation électrique sont situés dans l'aéronef, de préférence dans le fuselage de l'aéronef.The following description describes an embodiment considered at the time of filing as the best mode of realization this description provides an arrangement with a single entity called "POD" reported fixedly under the fuselage of the aircraft. Still according to this arrangement, a computer and a power supply are located in the aircraft, preferably in the fuselage of the aircraft.
Il est possible de prévoir des variantes agencées de façon différente par rapport au fuselage de l'aéronef mais reprenant intégralement les caractéristiques de la présente invention comme il sera mentionné ci-après.It is possible to provide variants arranged differently from the fuselage of the aircraft but fully incorporating the features of the present invention as will be mentioned below.
Selon le mode de réalisation préférentiel, le dispositif selon l'invention comprend un carter 10 prévu pour être rapporté sur le fuselage d'un aéronef tel que représenté sur la figure 1, ce carter étant également la structure support des différents organes constituant les éléments de détection et de visualisation dudit dispositif de surveillance.According to the preferred embodiment, the device according to the invention comprises a casing 10 intended to be attached to the fuselage of an aircraft as shown in FIG. 1, this casing being also the support structure of the various members constituting the elements of the aircraft. detection and visualization of said monitoring device.
Le positionnement de ce carter est avantageusement sous le fuselage, en partie médiane.The positioning of this casing is advantageously under the fuselage, partly median.
Ainsi lorsque l'aéronef est au sol, le carter se trouve sensiblement à hauteur d'homme pour un avion d'affaires même pour les modèles les plus gros.Thus when the aircraft is on the ground, the casing is substantially at man's height for a business jet even for the larger models.
Le boîtier ainsi que cela est visible sur les figures 2 et 3 comporte dans le mode de réalisation représenté, une bride périphérique destinée à être fixée sur la périphérie d'une ouverture de profil conjugué, ménagée dans ledit fuselage.The housing as shown in Figures 2 and 3 comprises in the embodiment shown, a peripheral flange to be fixed on the periphery of a conjugate profile opening formed in said fuselage.
Un tel dispositif comprend des moyens 12 d'alimentation électrique tels qu'une batterie. Cette batterie est rechargée par le système d'alimentation général de l'aéronef, lorsque l'alimentation principale ou annexe de l'avion est active. La batterie est d'une capacité de quelques ampères heure, en 28 volts comme il se doit en aéronautique et aux normes aéronautiques pour sa constitution. De telles batteries sont disponibles dans le commerce. Les contraintes liées à ces batteries conduisent à des produits très performants mais représentant un poids supplémentaire, croissant de façon rapide avec la capacité et il faut donc limiter fortement la puissance d'une telle batterie pour un système auxiliaire de sorte que le système de surveillance dans son ensemble contribue à une moindre augmentation du poids.Such a device comprises power supply means 12 such as a battery. This battery is recharged by the general power system of the aircraft, when the main or auxiliary power of the aircraft is active. The battery is of a capacity of a few amperes, in 28 volts as it should be in aeronautics and the aeronautical standards for its constitution. Such batteries are commercially available. The constraints related to these batteries lead to high performance products but representing an additional weight, growing rapidly with the capacity and it is therefore necessary to strongly limit the power of such a battery for an auxiliary system so that the monitoring system in together contributes to a lower weight increase.
Cette batterie est avantageusement logée dans le fuselage.This battery is advantageously housed in the fuselage.
De même, il est prévu un calculateur 14. Ce calculateur est prévu pour traiter les données du système et comme il n'a pas besoin d'accès sur l'extérieur de l'aéronef, comme il sera expliqué ci-après, il est également logé dans le fuselage.Likewise, a calculator 14 is provided. This calculator is intended to process the data of the system and since it does not need access on the outside of the aircraft, as will be explained below, it is also housed in the fuselage.
Il est à noter que le volume général du carter 10 est lui-même fortement réduit obligeant à une forte compacité de l'agencement intérieur. De fait, ce carter étant une source de perturbations de l 'aérodynamisme, il convient de le minimiser puisque la suppression totale est impossible et qu'il doit nécessairement faire saillie comme il sera indiqué par la suite.It should be noted that the general volume of the housing 10 is itself greatly reduced, requiring a high compactness of the interior arrangement. In fact, this housing being a source of aerodynamic disturbances, it should be minimized since total suppression is impossible and it must necessarily protrude as will be indicated later.
L'escamotage de ce carter et des composants qu'il contient pourrait être une solution mais elle rendrait beaucoup plus complexe l'agencement et surtout il s'agirait d'un système actif susceptible de provoquer des pannes et des immobilisations de l'appareil, ce qui serait totalement inadmissible.The retraction of this housing and the components it contains could be a solution but it would make the layout much more complex and above all it would be an active system likely to cause breakdowns and immobilizations of the apparatus, which would be totally inadmissible.
De fait, toute installation active du type escamotable obligerait à des certifications au même titre que les autres organes actifs de l'aéronef.In fact, any active installation of the retractable type would require certifications in the same way as the other active organs of the aircraft.
Un des intérêts du dispositif selon la présente invention est sa configuration statique même si le carter et son contenu restent amovibles à des fins de maintenance, nécessairement. Les composants internes au carter qui constituent le dispositif de surveillance proprement dit comprennent essentiellement des moyens 16 de détection par hyperfréquences, des moyens 18 de capture d'images.One of the advantages of the device according to the present invention is its static configuration even if the housing and its contents remain removable for maintenance purposes, necessarily. The components internal to the housing that constitute the monitoring device itself essentially comprise means 16 for detecting by microwave frequencies, means 18 for capturing images.
Il est utile de préciser que le dispositif selon l'invention ne se contente pas de déclencher une alarme en cas d'effraction mais bien de surveiller une zone donnée correspondant à un périmètre de sécurité autour de l'aéronef.It is useful to specify that the device according to the invention is not content to trigger an alarm in case of break-in but to monitor a given area corresponding to a security perimeter around the aircraft.
Ainsi, le dispositif surveille une zone donnée incluant l'environnement de l'aéronef grâce aux moyens 16 de détection, et, en cas de détection d'une intrusion dans ledit environnement, capte des images de l'environnement de l'aéronef grâce aux moyens 18 de capture d'images.Thus, the device monitors a given area including the environment of the aircraft through the detection means 16, and, in the event of detection of an intrusion into said environment, captures images of the environment of the aircraft thanks to the means 18 for capturing images.
Il est aussi prévu des moyens 20 de mémorisation et de traitement d'images, des moyens 22 de communication, des moyens 24 de pilotage de ces composants internes, ces moyens étant, dans l'agencement retenu, intégrés dans le calculateur.It is also provided means 20 for storing and image processing, means 22 for communication, means 24 for controlling these internal components, these means being, in the selected arrangement, integrated in the computer.
Les moyens 16 de détection par hyperfréquences sont logés de façon préférentielle en partie inférieure du carter 10 de sorte à pouvoir balayer 360° sans rencontrer d'obstacles.The microwave detection means 16 are preferably housed in the lower part of the housing 10 so that they can scan 360 ° without encountering obstacles.
Ces moyens 16 peuvent comprendre quatre antennes réceptrices et une antenne émettrice omnidirectionnelle ou comme dans le cas présent quatre antennes émeftrices 26 et une antenne 28 réceptrice omnidirectionnelle.These means 16 may comprise four receiving antennas and an omnidirectional transmitting antenna or as in the present case four emitter antennas 26 and an omnidirectional receiving antenna 28.
Ce choix est retenu pour sa capacité à permettre la gestion en engendrant une plus faible consommation d'énergie.This choice is retained for its ability to enable management by generating lower energy consumption.
Chaque antenne émettrice couvre un secteur légèrement supérieur à 90° afin de générer une superposition et de couvrir assurément 360°.Each transmitting antenna covers a sector slightly greater than 90 ° in order to generate a superposition and to cover certainly 360 °.
Le matériau qui constitue le carter et qui se situe au droit de ces antennes émeftrices et réceptrices est transparent aux hyperfréquences, ce qui ne pose pas de problèmes et peut être par exemple un matériau composite. On note dès lors que les problèmes liés à l'abrasion, au givre, au matériau spécifique des fenêtres comme dans le cas des rayonnements infrarouges par exemple, à la capture des rayonnements est supprimé, ce qui est une réponse de la présente invention au problème posé.The material constituting the casing and located at the right of these transmitting and receiving antennas is transparent to the microwave, which is not a problem and can be for example a composite material. It is therefore noted that the problems associated with abrasion, with frost, with the specific material of the windows, as in the case of infrared radiation, for example, with the capture of the radiations, are suppressed, which is a response of the present invention to the problem. posed.
De plus, ces moyens 16 de détection sont insensibles à la chaleur, au froid et ne provoquent pas de déclenchements intempestifs liés à ces paramètres.In addition, these detection means 16 are insensitive to heat, cold and do not cause inadvertent tripping related to these parameters.
Le choix des fréquences retenues reste tout à fait dans le domaine de compétence de l'homme de l'art car le choix de cette fréquence est lié à la réglementation et aux normes concernant les communications qui définissent des plages de fréquences interdites donc des plages de fréquences accessibles.The choice of the frequencies retained remains entirely within the skill of the person skilled in the art because the choice of this frequency is linked to the regulations and standards concerning communications which define forbidden frequency ranges, therefore ranges of accessible frequencies.
La portée de ces moyens 16 de détection par hyperfréquences est de l'ordre deThe scope of these microwave detection means 16 is of the order of
5 à 50 mètres pour fixer un ordre de grandeur.5 to 50 meters to set an order of magnitude.
Ces moyens 16 de détection par hyperfréquences déclenchent un signal dès que l'antenne réceptrice capte au moins une perturbation dans son champ de contrôle.These microwave detection means 16 trigger a signal as soon as the receiving antenna picks up at least one disturbance in its control field.
Ce signal est transmis aux moyens 24 de pilotage.This signal is transmitted to the control means 24.
Les moyens 18 de capture d'images dans le mode de réalisation préférentiel retenu comprennent au moins une caméra et en l'occurrence quatre caméras 30, numériques. Chaque caméra dispose d'une couverture avec un angle de 90° environ.The image capture means 18 in the preferential embodiment retained comprise at least one camera and in this case four digital cameras 30. Each camera has a cover with an angle of about 90 °.
Ces caméras sont gérées par les moyens 24 de pilotage comme il sera décrit ultérieurement.These cameras are managed by the control means 24 as will be described later.
Ces caméras sont également gourmandes en énergie et elles sont associées à un interrupteur séquentiel 32 qui permet de provoquer une capture d'images sur une seule caméra à la fois mais successivement, par permutation circulaire et à une fréquence ires élevée, plusieurs fois par seconde pour donner un ordre d'idée. Ainsi, il est possible à partir de chaque caméra de disposer d'images animées, d'une qualité, notamment d'une définition largement suffisante pour constater sans aucune difficulté l'intrusion, tout en réduisant sensiblement la consommation énergétique.These cameras are also energy-hungry and they are associated with a sequential switch 32 which makes it possible to provoke an image capture on a single camera at a time but successively, by circular permutation and at a high frequency, several times per second for give an idea. Thus, it is possible from each camera to have animated images, a quality, including a largely sufficient definition to see without difficulty the intrusion, while significantly reducing energy consumption.
Cette conduite du parc de caméras est transparente et imperceptible pour la personne en charge de la lecture des images.This driving of the camera park is transparent and imperceptible to the person in charge of reading the images.
Au sein du calculateur, les moyens 20 de traitement et de mémorisation des images acquises par chacune des caméras permettent une compression des fichiers numériques de sorte à permettre une mémorisation par exemple sur une carte mémoire de type Secure Digital SD dont le temps d'accès est très rapide et dont la capacité est suffisante pour mémoriser les séquences d'intrusion dans le champ des caméras.Within the computer, the means 20 for processing and storing the images acquired by each of the cameras allow compression of the digital files so as to allow storage, for example on a Secure Digital SD memory card whose access time is very fast and whose capacity is sufficient to memorize the sequences of intrusion in the field of the cameras.
Ces moyens 20 de traitement et de mémorisation sont accessibles et gérés par les moyens 24 de pilotage intégrés au calculateur.These processing and storage means 20 are accessible and managed by the control means 24 integrated in the computer.
Les moyens 22 de transmission comprennent un émetteur/récepteur 34 de même type que dans le domaine de la téléphonie sans fil et apte à fonctionner sur le réseau de téléphonie sans fil.Transmission means 22 comprise a transmitter / receiver 34 of the same type as in the field of wireless telephony and capable of operating on the wireless telephone network.
Ces moyens de transmission autorisent l'envoi de fichiers et l'envoi et la réception d'instructions des moyens 24 de pilotage à partir d'un téléphone mobile sur un réseau téléphonique sans fil et/ou par le biais d'un réseau de communication de proximité par une connexion sans fil privée comme celle dénommée "Bluetooth" par exemple.These transmission means allow the sending of files and the sending and receiving of instructions 24 means of control from a mobile phone on a wireless telephone network and / or through a communication network close by a private wireless connection like the one called "Bluetooth" for example.
Ainsi, l'opérateur peut effectuer de très nombreuses interventions comme :Thus, the operator can perform many interventions such as:
- rechercher dans les fichiers enregistrés pour les visualiser, caméra par caméra,- search in recorded files to view them, camera by camera,
- faire cesser une alarme s'il juge qu'il n'est plus nécessaire de poursuivre la surveillance de l'intrusion,- stop an alarm if it deems that it is no longer necessary to continue monitoring the intrusion,
- effacer des fichiers sauvegardés, - déclencher une ou plusieurs caméras à la demande pour vérifier sans même qu'il y ait une intrusion détectée, et- delete saved files, - trigger one or more cameras on demand to check without even having a detected intrusion, and
- avoir accès à distance à toutes les fonctions du dispositif de surveillance. Comme indiqué, il peut en outre être prévu de façon optionnelle une communication supplémentaire dite de proximité de type "Bluetooth". En effet, en cas de non couverture par le réseau de téléphonie mobile, en cas de panne totale, en cas de rupture temporaire de la liaison ou simplement pour opérer en mode local à proximité de l'appareil, sur interrogation du système, l'opérateur est informé dès son arrivée dans la zone de couverture de proximité d'une alerte sur son portable.- have remote access to all the functions of the monitoring device. As indicated, it may further be optionally provided an additional communication called proximity "Bluetooth" type. Indeed, in case of non coverage by the mobile network, in case of total failure, in case of temporary break of the link or simply to operate in local mode near the device, on interrogation of the system, the operator is informed upon arrival in the proximity coverage area of an alert on his / her mobile.
Ceci permet alors de visualiser le type d'intrusion et de procéder aux vérifications préalablement à l'arrivée à proximité immédiate de l'aéronef.This then makes it possible to visualize the type of intrusion and to carry out verifications prior to arrival in the immediate vicinity of the aircraft.
Le procédé de fonctionnement du dispositif selon l'invention est maintenant décrit de façon simple à partir d'un cas concret.The operating method of the device according to the invention is now described in a simple way from a concrete case.
Lorsque le propriétaire ou toute personne en charge de la surveillance de l'avion quitte l'avion, il met en service le dispositif de surveillance volontairement ou le système prévient après un certain délai que le dispositif n'est pas en service.When the owner or any person in charge of the surveillance of the airplane leaves the aircraft, it activates the monitoring device voluntarily or the system warns after a certain period that the device is not in service.
Il est aussi possible de prévoir une mise en service automatiquement une fois certaines actions engagées comme l'arrêt des moteurs durant une durée déterminée.It is also possible to provide automatic commissioning once certain actions have been taken such as stopping the engines for a specified period.
Les moyens 16 de détection par hyperf réquences sont en service et les antennes émeftrices balayent leurs secteurs, l'antenne réceptrice assurant la détection d'une perturbation du champ surveillé, notamment lors d'une intrusion.The microwave detection means 16 are in use and the emitter antennas scan their sectors, the receiving antenna ensuring the detection of a disturbance of the monitored field, especially during an intrusion.
Dès lors, les moyens de pilotage déclenchent une alarme et une transmission d'un signal au propriétaire ou au responsable de la surveillance de l'avion. Ce signal est avantageusement un SMS (Short Message Service). Simultanément les caméras sont mises en service, de préférence de façon séquentielle, comme indiqué ci-avant, les images acquises étant traitées notamment comprimées et mémorisées.Therefore, the control means trigger an alarm and a transmission of a signal to the owner or the person responsible for monitoring the aircraft. This signal is advantageously an SMS (Short Message Service). Simultaneously the cameras are put into service, preferably sequentially, as indicated above, the acquired images being processed in particular compressed and stored.
Bien entendu, lors d'une intrusion, il est possible de prévoir uniquement le déclenchement de la caméra en fonction de la détection de cette intrusion dans la zone correspondante, à enregistrer les images individuelles ainsi captées et à les traiter de sorte à disposer d'une image continue lors de la visualisation.Of course, during an intrusion, it is possible to provide only the triggering of the camera according to the detection of this intrusion into the corresponding area, to record the individual images thus captured and to process them so as to have access to a continuous image when viewing.
Le propriétaire ou le responsable de la surveillance peut alors consulter en très léger différé les images acquises et prendre les mesures qui s'imposent en cas de constatation d'une intrusion.The owner or the person responsible for surveillance can then consult with very slight deferred images acquired and take the necessary measures in case of discovery of an intrusion.
S'il s'agit d'une alarme engendrée par le passage dans le champ surveillé d'un animal de taille suffisante pour avoir provoqué un déclenchement, l'opérateur le constate et n'engage pas d'action spécifique.If it is an alarm caused by the passage in the guarded field of an animal of sufficient size to have triggered, the operator finds and does not engage any specific action.
S'il s'agit de toute autre intrusion, il agit en conséquence.If it is any other intrusion, it acts accordingly.
Il est à noter que la couverture permet de capter les images sur 360° donc de fournir toutes les informations même s'il y a plusieurs personnes provenant de directions différentes.It should be noted that the cover captures images 360 ° so provide all the information even if there are several people from different directions.
Les moyens de détection recourant à des hyperfréquences utilisent l'effetMicrowave detection means use the effect
Doppler bien connu dont les perturbations par des éléments extérieurs non liés à une intrusion sont très limités ce qui exclut un nombre significatif d'alarmes intempestives.Doppler well known whose disturbances by external elements not related to an intrusion are very limited which excludes a significant number of untimely alarms.
Si l'opérateur veut constater l'environnement immédiat de l'avion, par exemple la présence éventuelle d'un avion venu se parquer à proximité, il peut visualiser grâce à chaque caméra le champ concerné.If the operator wants to see the immediate environment of the aircraft, for example the possible presence of a plane parked nearby, he can visualize with each camera the field concerned.
Dans ce cas, la portée de la caméra est bien supérieure à celle de déclenchement des moyens de détection, grâce à une grande profondeur de champ.In this case, the range of the camera is much greater than that of triggering the detection means, thanks to a large depth of field.
Les moyens de détection doivent être limités au seul périmètre agrandi de l'avion pour qu'ils ne soient pas perturbés par les mouvements réguliers et normaux de personnels et d'engins sur le terrain qui déclencheraient des alarmes non pertinentes.The means of detection must be limited to the enlarged perimeter of the airplane so that they are not disturbed by the regular and normal movements of the aircraft. personnel and equipment on the ground that would trigger irrelevant alarms.
Le dispositif de surveillance selon l'invention, dans sa version carter fixe, est complété par une caméra CA dite d'agrément. Cette caméra est logée dans le carter 10 et elle se situe sur l'avant avec un angle d'inclinaison de sorte à pouvoir acquérir des images du sol plus particulièrement pendant les phases de décollage et d'atterrissage. Avantageusement la caméra est une caméra couleur et les images sont retransmises sur des moniteurs en places passagers pour l'agrément du vol, ces images venant compléter de façon attractive et inf ormative la vision par les hublots.The monitoring device according to the invention, in its fixed housing version, is completed by a so-called CA approval camera. This camera is housed in the housing 10 and it is located on the front with a tilt angle so as to acquire images of the ground especially during the take-off and landing phases. Advantageously the camera is a color camera and the images are transmitted on monitors in passenger seats for the pleasure of the flight, these images complementing in an attractive and inf ormative way the vision through the portholes.
La plupart des problématiques exposées concernant l'invention n'ont plus lieu d'être notamment les problèmes de consommation puisqu'il s'agit d'un fonctionnement uniquement durant le vol, moteurs en marche donc avec génération de courant.Most of the problems described in relation to the invention are no longer relevant in particular to the problems of consumption since it is an operation only during the flight, engines running with current generation.
Selon la présente invention, il est possible de prévoir en fonction des besoins, des types d'aéronefs et de la demande des constructeurs d'aéronefs un agencement qui reprend strictement les mêmes moyens fonctionnant de la même façon mais avec une configuration modifiée.According to the present invention, it is possible to provide, as a function of the needs, the types of aircraft and the request of the aircraft manufacturers, an arrangement which strictly uses the same means operating in the same way but with a modified configuration.
C'est ainsi que les moyens 16 de détection par hyperfréquences sont logés de façon préférentielle en partie inférieure du carter 10 de sorte à pouvoir balayerThus, the microwave detection means 16 are preferably housed in the lower part of the housing 10 so that they can be swept away.
360° sans rencontrer d'obstacle mais ces moyens 16 pourraient être positionnés dans un premier carter indépendant et relié au calculateur tandis que les caméras de surveillance seraient logées dans un second carter également reliées au calculateur.360 ° without encountering obstacles, but these means 16 could be positioned in a first independent housing and connected to the computer while the surveillance cameras would be housed in a second housing also connected to the computer.
Cette séparation des fonctions et des constituants peut être intéressante dans le cas où la mise en saillie doit être réduite. En effet, le nombre de carter est multiplié par deux mais les perturbations aérodynamiques engendrées par ces deux carters de plus petites dimensions peuvent être inférieures à celle d'un seul carter de plus grandes dimensions. Néanmoins, il subsiste la nécessité de deux intégrations dans le fuselage.This separation of functions and constituents may be of interest in the case where the projection has to be reduced. Indeed, the number of crankcase is multiplied by two but the aerodynamic disturbances generated by these two crankcases of smaller dimensions can be lower than that of a crankcase. only larger casing. Nevertheless, there remains the need for two integrations in the fuselage.
Le choix reste donc une question de compromis et ne modifie pas les caractéristiques de la présente invention.The choice therefore remains a question of compromise and does not modify the characteristics of the present invention.
Ces moyens 16 comprennent de façon avantageuse quatre antennes émettricesThese means 16 advantageously comprise four transmitting antennas
26 et une antenne 28 réceptrice omnidirectionnelle avec les composants actuellement disponibles sur le marché mais quatre récepteurs et un émetteurs omnidirectionnel peuvent également donner satisfaction.26 and an omnidirectional receiver antenna 28 with the currently available components on the market but four receivers and an omnidirectional transmitters can also give satisfaction.
En ce qui concerne les variantes d'agencement, il peut aussi exister une demande de carter amovible. Dans ce cas, le carter est relié aux organes situés dans le fuselage à savoir batterie et calculateur par un câblage adapté muni d'au moins une connexion de sorte à retirer aisément le carter et son contenu avant le vol et à pouvoir le ré installer une fois l'aéronef posé et parqué.With regard to the variant arrangements, there may also be a request for a removable casing. In this case, the housing is connected to the bodies located in the fuselage namely battery and computer by a suitable wiring provided with at least one connection so as to easily remove the housing and its contents before the flight and to be able to re install a once the aircraft is parked and parked.
Il convient aussi de prévoir des moyens de liaison au fuselage simples et fiables avec une trappe d'obturation du logement laissé libre après le retrait du carter pour les phases de vol. It is also necessary to provide simple and reliable fuselage connection means with a shutter of the housing left free after removal of the casing for flight phases.
