Description
UNITE DE SERVICE POUR PASSAGER ET SYSTEME CORRESPONDANT PASSENGER SERVICE UNIT AND CORRESPONDING SYSTEM
L'invention concerne une unité de service pour passager ainsi qu'un système général incorporant plusieurs desdites unités de service. The invention relates to a passenger service unit as well as a general system incorporating several of said service units.
ARRIERE PLAN DE L'INVENTION BACKGROUND OF THE INVENTION
Dans le contexte épidémiologique actuel de pandémie COVID 19, de nouveaux besoins sont apparus pour assurer la pro- tection de la population. En ce qui concerne le domaine aé ronautique, il faut ainsi assurer la protection des passa gers, des équipes au sol ainsi que des équipages. In the current epidemiological context of the COVID 19 pandemic, new needs have arisen to ensure the protection of the population. As regards the aeronautical field, it is thus necessary to ensure the protection of passengers, ground crews and crews.
Il semble donc nécessaire de faire intervenir des agents de maintenance entre deux vols pour nettoyer et désinfecter un avion. Par ailleurs, au cours d'un vol, l'équipage devra surveiller les passagers pour s'assurer que les gestes bar rières sont bien respectés et/ou identifier les passagers potentiellement malades pour les isoler. It therefore seems necessary to bring in maintenance agents between two flights to clean and disinfect an aircraft. Furthermore, during a flight, the crew must monitor the passengers to ensure that the barrier gestures are respected and / or identify potentially sick passengers in order to isolate them.
De telles solutions s'avèrent évidemment fastidieuses à mettre en œuvre. Such solutions obviously prove to be tedious to implement.

DESCRIPTION DETAILLEE DE L'INVENTION On a représenté à la figure 3 un avion 1 dont la cabine 2 est remplie par au moins deux colonnes de sièges séparées par un couloir, les sièges étant organisés par rangée au sein de chaque colonne. DETAILED DESCRIPTION OF THE INVENTION FIG. 3 shows an airplane 1, the cabin 2 of which is filled with at least two columns of seats separated by a corridor, the seats being organized by row within each column.
A chaque rangée de sièges de chaque colonne est associée une unité de service pour passager 3 (dont une partie seu lement est référencée ici) selon un mode de réalisation particulier de l'invention, unité agencée au-dessus de la rangée de sièges associée. Par la suite on pourra parler de ex-PSU (pour Passenger Service Unit) pour les unités de service pour passager de l'art antérieur et d'EPSU (pour Enhanced Personal Service Unit) pour l'unité de service pour passager 3 selon ledit mode de réalisation particulier de l'invention. Each row of seats in each column is associated with a passenger service unit 3 (only a part of which is referenced here) according to a particular embodiment of the invention, a unit arranged above the associated row of seats. Subsequently we can speak of ex-PSU (for Passenger Service Unit) for the passenger service units of the prior art and EPSU (for Enhanced Personal Service Unit) for the service unit. for passenger 3 according to said particular embodiment of the invention.
L'ensemble des EPSU forme ici un système général EPSU dans 1'avion 1. Par ailleurs, l'avion 1 comporte un serveur central 4 de données et d'applications. Le serveur central 4 est par exemple un Serveur de Système de Gestion (plus connu sous l'acronyme anglais de NSS pour « Network System Server »). De préférence, ledit serveur central 4 pilote le système général EPSU. All the EPSUs here form a general EPSU system in the airplane 1. Furthermore, the airplane 1 comprises a central server 4 for data and applications. The central server 4 is for example a Management System Server (better known by the acronym of NSS for “Network System Server”). Preferably, said central server 4 controls the general EPSU system.
L'avion 1 comporte également au moins une interface de com munication avion/équipage 5 (de type panneau de contrôle ou en anglais CCP pour « Cabin Control Panel » et/ou de type panneau de commande ou en anglais FAP pour « Flight Atten- dant Panel »). De préférence, ladite interface de communi cation avion/équipage 5 permet entre autres à l'équipage d'interagir avec le système général EPSU via le serveur central 4. The airplane 1 also includes at least one airplane / crew communication interface 5 (of the control panel type or in English CCP for “Cabin Control Panel” and / or of the control panel type or in English FAP for “Flight Attend- dant Panel ”). Preferably, said aircraft / crew communication interface 5 allows, inter alia, the crew to interact with the general EPSU system via the central server 4.
Dans le cas présent, les EPSU sont toutes identiques entre elles de sorte que la description qui suit d'une EPSU est applicable à toutes les autres EPSU du système général EPSU. In the present case, the EPSUs are all identical to each other so that the following description of an EPSU is applicable to all the other EPSUs of the general EPSU system.
En référence aux figures 1 et 2, l'EPSU comporte de préfé rence un module de calcul (comme par exemple un processeur) et/ou un module mémoire (comme par exemple une mémoire de masse) qui ne sont pas représentés ici. With reference to FIGS. 1 and 2, the EPSU preferably comprises a calculation module (such as for example a processor) and / or a memory module (such as for example a mass memory) which are not represented here.
Par ailleurs l'EPSU comporte au moins un sous-ensemble et de préférence une pluralité de sous-ensembles, chaque sous- ensemble permettant de remplir au moins une fonction. Dans le cas présent, l'EPSU comporte au moins un sous-ensemble et de préférence au moins deux sous-ensembles et de préfé rence au moins trois sous-ensembles et de préférence au moins quatre sous-ensembles permettent chacun de remplir une fonction d'amélioration de la sécurité sanitaire à l'intérieur de l'avion. On va à présent décrire ces différents quatre sous-en sembles. Furthermore, the EPSU comprises at least one sub-assembly and preferably a plurality of sub-assemblies, each sub-assembly making it possible to fulfill at least one function. In the present case, the EPSU comprises at least one sub-assembly and preferably at least two sub-assemblies and preferably at least three sub-assemblies and preferably at least four sub-assemblies each make it possible to fulfill a function of 'improved health security inside the aircraft. We will now describe these different four sub-groups.
Le premier sous-ensemble 11 comporte au moins deux disposi tifs de prise d'images 21a, 21b pour générer en service une vision stéréoscopique du ou des passagers assis dans la rangée de sièges considérée. The first sub-assembly 11 comprises at least two image-taking devices 21a, 21b for generating in service a stereoscopic vision of the passenger or passengers seated in the row of seats in question.
Au moins l'un des dispositifs de prise d'images21a, 21b travaille par exemple dans le domaine visible. At least one of the image-taking devices 21a, 21b works for example in the visible range.
Au moins l'un des dispositifs de prise d'images21a, 21b peut être monté mobile dans l'EPSU de sorte à pouvoir ba layer la rangée de sièges considérée et/ou au moins l'un des dispositifs de prise d'images 21a, 21b est fixe. At least one of the image-taking devices 21a, 21b can be mounted mobile in the EPSU so as to be able to layer the row of seats in question and / or at least one of the image-taking devices 21a, 21b is fixed.
Au moins l'un des dispositifs de prise d'images 21a, 21b, et de préférence tous les dispositifs de prise d'images du premier sous-ensemble 11, sont des caméras, telles que des caméras vidéo et/ou des caméras miniatures et/ou des camé ras RVB. At least one of the image capture devices 21a, 21b, and preferably all the image capture devices of the first sub-assembly 11, are cameras, such as video cameras and / or miniature cameras and / or rgb flush cameras.
A partir des informations générées par au moins les dispo sitifs de prise d'images 21a, 21b, une vision stéréosco- pique est générée soit par le premier sous-ensemble 11 lui- même soit par le module de calcul de l'EPSU soit par le serveur central 4. From the information generated by at least the image-taking devices 21a, 21b, a stereoscopic vision is generated either by the first sub-assembly 11 itself or by the calculation module of the EPSU or by the central server 4.
Un traitement des images de ladite vision stéréoscopique effectué ultérieurement permet ainsi de détecter desdites images le non-respect éventuel de règles de sécurité sani taires (tel que par exemple le port du masque, la distance à respecter entre deux passagers ...). Ce traitement est as suré par un dispositif de traitement d'image intégré dans le premier sous-ensemble 11 lui-même, dans l'EPSU ou dans le serveur central 4. Subsequent processing of the images of said stereoscopic vision thus makes it possible to detect from said images any possible non-compliance with health safety rules (such as, for example, wearing a mask, the distance to be observed between two passengers, etc.). This processing is ensured by an image processing device integrated in the first sub-assembly 11 itself, in the EPSU or in the central server 4.
Optionnellement, un signal d'alarme peut alors être généré à destination de l'équipage par exemple via l'interface de communication avion/équipage 5. Optionally, an alarm signal can then be generated for the crew, for example via the aircraft / crew communication interface 5.
Le premier sous-ensemble 11 permet ainsi de remplir une fonction d'amélioration de la sécurité sanitaire. Préférentiellement, l'EPSU est agencée de sorte à pouvoir observer non seulement la rangée de sièges considérée mais également la rangée de sièges adjacente immédiatement agen cée devant. A cet effet, et comme plus visible à la figure 6, l'EPSU comporte un premier sous-ensemble bis 11' iden- tique au premier sous-ensemble 11 mais agencé de sorte que les dispositifs de prise d'images 21a', 21b' du premier sous-ensemble bis 11' permettent la génération d'une vision stéréoscopique de la rangée de sièges adjacente immédiate ment agencée devant. On assure ainsi une redondance de la surveillance des pas sagers puisque chaque rangée de siège peut être observée par deux premiers sous-ensembles de deux EPSU adjacents.The first sub-assembly 11 thus makes it possible to fulfill a function of improving health security. Preferably, the EPSU is arranged so as to be able to observe not only the row of seats in question but also the adjacent row of seats immediately arranged in front. For this purpose, and as more visible in FIG. 6, the EPSU comprises a first sub-assembly bis 11 'identical to the first sub-assembly 11 but arranged so that the image-taking devices 21a', 21b 'of the first sub-assembly bis 11' allow the generation of a stereoscopic view of the adjacent row of seats immediately arranged in front. This ensures redundancy in the monitoring of the sager steps since each row of seats can be observed by two first subsets of two adjacent EPSUs.
En cas d'existence d'un premier sous-ensemble bis 11', le dispositif de traitement d'images pourra être commun au premier sous-ensemble 11 et au premier sous-ensemble bis 11 If there is a first sub-assembly bis 11 ', the image processing device may be common to the first sub-assembly 11 and to the first sub-assembly bis 11
Le deuxième sous-ensemble 12 comporte au moins un capteur de température 22 pour mesurer en service la température corporelle du ou des passagers assis dans la rangée de sièges considérée. The second sub-assembly 12 comprises at least one temperature sensor 22 for measuring, in service, the body temperature of the passenger or passengers seated in the row of seats in question.
Le capteur de température 22 peut être monté mobile dans l'EPSU de sorte à pouvoir balayer la rangée de sièges con sidérée ou être fixe. The temperature sensor 22 can be movably mounted in the EPSU so as to be able to sweep the row of seats under consideration or be stationary.
Le capteur de température 22 peut être agencé entre les deux dispositifs de prise d'images 21a, 21b du premier sous-ensemble et/ou au-dessus desdits dispositifs de prise d'images 21a, 21b. The temperature sensor 22 can be arranged between the two image-taking devices 21a, 21b of the first sub-assembly and / or above said image-taking devices 21a, 21b.
Le capteur de température 22 est par exemple un capteur travaillant dans l'infrarouge. De préférence, le capteur de température 22 est une caméra thermique infrarouge. The temperature sensor 22 is for example a sensor working in the infrared. Preferably, the temperature sensor 22 is an infrared thermal camera.
Par exemple le capteur de température 22 avec un champ suf fisamment large pour pourvoir viser tous les sièges de la rangée de siège associée à l'EPSU. Par exemple le capteur de température 22 est une caméra avec un champ compris entre 100 et 140 degrés et typiquement 120 degrés. A partir des informations générées par la caméra infra rouge, une vision infrarouge est générée soit par le deu xième sous-ensemble 12 lui-même soit par le module de cal cul de l'EPSU soit par le serveur central 4. Or comme visible à la figure 6, les passagers rayonnent différemment en infrarouge selon leurs températures corpo relles. For example the temperature sensor 22 with a sufficiently wide field to be able to target all the seats of the row of seats associated with the EPSU. For example the temperature sensor 22 is a camera with a field of between 100 and 140 degrees and typically 120 degrees. From the information generated by the infrared camera, an infrared vision is generated either by the second sub-assembly 12 itself or by the calculation module of the EPSU or by the central server 4. Now as visible from FIG. 6, passengers radiate differently in infrared according to their body temperatures.
Un traitement des images de ladite vision infrarouge effec tué ultérieurement permet ainsi de détecter desdites images une zone de l'avion 1 où la température corporelle des pas sagers est plus élevée que la normale potentiellement syno nyme de la présence d'un passager malade. Ce traitement est assuré par un dispositif de traitement d'image intégré dans le deuxième sous-ensemble 12 lui-même, dans l'EPSU ou dans le serveur central 4. Subsequent processing of the images of said infrared vision thus makes it possible to detect from said images a zone of the airplane 1 where the body temperature of the saging steps is higher than normal, potentially synonymous with the presence of a sick passenger. This processing is provided by an image processing device integrated in the second sub-assembly 12 itself, in the EPSU or in the central server 4.
Optionnellement, un signal d'alarme peut alors être généré à destination de l'équipage par exemple via l'interface de communication avion/équipage 5. Optionally, an alarm signal can then be generated for the crew, for example via the aircraft / crew communication interface 5.
Le deuxième sous-ensemble 12 permet ainsi de remplir une fonction d'amélioration de la sécurité sanitaire. The second sub-assembly 12 thus makes it possible to fulfill a function of improving health security.
Préférentiellement, l'EPSU est agencée de sorte à pouvoir contrôler non seulement la rangée de sièges considérée mais également la rangée de sièges adjacente immédiatement agen cée devant. A cet effet, et comme plus visible à la figure 6, l'EPSU comporte un deuxième sous-ensemble bis 12' iden tique au deuxième sous-ensemble 12 mais agencé de sorte que le capteur de température 22' du deuxième sous-ensemble bis 12' permettent de viser la rangée de sièges adjacente immé diatement agencée devant. On assure ainsi une redondance de la surveillance des pas sagers puisque chaque rangée de siège peut être observée par deux deuxièmes sous-ensembles de deux EPSU adjacents.Preferably, the EPSU is arranged so as to be able to control not only the row of seats considered but also the adjacent row of seats immediately arranged in front. To this end, and as more visible in FIG. 6, the EPSU comprises a second sub-assembly bis 12 'identical to the second sub-assembly 12 but arranged so that the temperature sensor 22' of the second sub-assembly bis 12 'make it possible to target the adjacent row of seats immediately arranged in front. This ensures redundancy in the monitoring of the sager steps since each row of seats can be observed by two second sub-assemblies of two adjacent EPSUs.
En cas d'existence d'un deuxième sous-ensemble bis 12', le dispositif de traitement d'images pourra être commun au deuxième sous-ensemble 12 et au deuxième sous-ensemble bis 12'. De préférence le premier sous-ensemble 11 (et/ou le premier sous-ensemble bis 11') et le deuxième sous-ensemble 12 (et/ou le deuxième sous-ensemble bis 12') sont corrélés entre eux afin que le traitement d'images de la vision in- frarouge soit effectué en regard de la vision stéréosco pique : le traitement de la vision infrarouge est ainsi plus précis. Il est ainsi possible de localiser directement un passager spécifique dont la température corporelle est trop élevée. Le dispositif de traitement d'images pourra ainsi être com mun au premier sous-ensemble 11 (et/ou au premier sous-en semble bis 11') et au deuxième sous-ensemble 12 (et/ou au deuxième sous-ensemble bis 12'). If there is a second sub-assembly bis 12 ', the image processing device may be common to the second sub-assembly 12 and to the second sub-assembly bis 12'. Preferably, the first sub-assembly 11 (and / or the first sub-assembly bis 11 ') and the second sub-assembly 12 (and / or the second sub-assembly bis 12') are correlated with each other so that the processing of The infrared vision images are taken opposite the stereoscopic vision: the processing of the infrared vision is thus more precise. It is thus possible to directly locate a specific passenger whose body temperature is too high. The image processing device can thus be common to the first sub-assembly 11 (and / or to the first sub-assembly bis 11 ') and to the second sub-assembly 12 (and / or to the second sub-assembly bis 12 ').
Le troisième sous-ensemble 13 comporte au moins un projec- teur de rayons ultraviolets pour projeter des rayons ultra violets sur la rangée de sièges considérée. The third sub-assembly 13 comprises at least one ultraviolet ray projector for projecting ultraviolet rays on the row of seats in question.
Ainsi, la mise en œuvre de tous les projecteurs de tous les EPSU du système général EPSU permet de couvrir un large vo lume de la cabine voire la majorité dudit volume. Le troisième sous-ensemble 13 permet ainsi de remplir une fonction d'amélioration de la sécurité sanitaire en parti cipant ainsi au nettoyage de la cabine 2 voire à sa débac- térisation et ce sans intervention humaine autre qu'une ac tivation éventuelle du troisième sous-ensemble 13. Le projecteur est par exemple un projecteur ultraviolet à LED. Thus, the use of all the headlamps of all the EPSUs of the general EPSU system makes it possible to cover a large volume of the cabin or even the majority of said volume. The third sub-assembly 13 thus makes it possible to fulfill a function of improving health security by thus participating in the cleaning of the cabin 2 or even in its debacterization and this without human intervention other than a possible activation of the third sub-assembly. assembly 13. The projector is for example an ultraviolet LED projector.
De préférence, le projecteur permet l'émission de rayons ultraviolets de type C et par exemple permet l'émission de rayons ultraviolets de longueurs d'ondes comprises entre 250 et 300 nanomètres et par exemple 250 nanomètres. Preferably, the projector allows the emission of ultraviolet rays of type C and for example allows the emission of ultraviolet rays of wavelengths between 250 and 300 nanometers and for example 250 nanometers.
De préférence, le troisième sous-ensemble 13 comporte des moyens de réglage de la puissance des rayonnements émis par le projecteur et/ou est configuré de sorte que le projec teur puisse fonctionner selon au moins deux modes de fonc- tionnement différent, à chaque mode de fonctionnement cor respondant une longueur d'ondes de rayons particulière. Préférentiellement, si des passagers sont présents dans la cabine 2, le projecteur est arrêté ou fonctionne à puis sance réduite ou à une longueur d'onde plus proche du vi sible. Préférentiellement encore, si la cabine 2 est vide, le projecteur fonctionne à puissance maximale ou à une lon gueur d'onde plus éloignée du visible. Preferably, the third sub-assembly 13 comprises means for adjusting the power of the radiations emitted by the projector and / or is configured so that the projector can operate according to at least two different operating modes, in each mode. operating mode corresponding to a particular wavelength of rays. Preferably, if passengers are present in cabin 2, the projector is stopped or operates at reduced power or at a wavelength closer to the visible. Again preferably, if the booth 2 is empty, the projector operates at maximum power or at a wavelength farther from the visible.
Par exemple la cabine 2 peut être nettoyée par rayonnement ultraviolets dans un délai de quelques dizaines de minutes à quelques heures pour une puissance de rayonnement de quelques Watts par projecteur. Ceci est avantageusement compatible avec les temps usuels de maintien au sol d'un avion entre deux vols. En outre, le(s) projecteur(s) ne consomme (nt) qu'une partie seulement de la puissance élec trique disponible par EPSU. De préférence, le troisième sous-ensemble 13 comporte un projecteur pour chaque siège de la rangée de siège considé rée. For example, the cabin 2 can be cleaned by ultraviolet radiation within a period of a few tens of minutes to a few hours for a radiation power of a few Watts per projector. This is advantageously compatible with the usual times for keeping an airplane on the ground between two flights. In addition, the projector (s) consumes only part of the electrical power available by EPSU. Preferably, the third sub-assembly 13 comprises a projector for each seat of the row of seats considered.
Les projecteurs 23a, 23b, 23c sont par exemple agencés sous les dispositifs de prise d'images 21a, 21b du premier sous- ensemble 11 et sous le capteur de température 22 du deu xième sous-ensemble 12. Les projecteurs sont tous iden tiques entre eux. The projectors 23a, 23b, 23c are for example arranged under the image capture devices 21a, 21b of the first sub-assembly 11 and under the temperature sensor 22 of the second sub-assembly 12. The projectors are all identical between them.
Préférentiellement, l'EPSU est agencée de sorte à pouvoir projeter des rayons ultraviolets non seulement sur la ran- gée de sièges considérée mais également la rangée de sièges adjacente immédiatement agencée devant. A cet effet, et comme plus visible à la figure 5, l'EPSU comporte un troi sième sous-ensemble bis 13' identique au troisième sous-en semble 13 mais agencé de sorte que les projecteurs du troi- sième sous-ensemble bis 13' puissent viser la rangée de sièges adjacente immédiatement agencée devant. Preferably, the EPSU is arranged so as to be able to project ultraviolet rays not only on the row of seats considered but also the adjacent row of seats immediately arranged in front. To this end, and as more visible in FIG. 5, the EPSU comprises a third sub-assembly bis 13 'identical to the third sub-assembly 13 but arranged so that the projectors of the third sub-assembly bis 13 'can aim at the adjacent row of seats immediately arranged in front.
On renforce ainsi l'action nettoyante de l'EPSU puisque chaque EPSU peut bombarder par rayons ultraviolets deux rangées de sièges adjacentes. This reinforces the cleaning action of the EPSU since each EPSU can bombard two adjacent rows of seats with ultraviolet rays.
En outre les projecteurs peuvent ainsi projeter des rayons ultraviolets sur les sièges de la rangée considérée et de la rangée de devant, et ainsi avantageusement sur les zones des sièges associés réceptrices des postillons potentielle ment chargés de virus. In addition, the headlamps can thus project ultraviolet rays onto the seats of the row in question and of the front row, and thus advantageously on the areas of the associated seats receiving postilions potentially laden with virus.
En variante, le EPSU ne comporte que le troisième sous-en- semble 13 (et non le troisième sous-ensemble bis 13'). Dans ce cas et de préférence, les projecteurs 23a, 23b, 23c sont disposés de manière à pouvoir rayonner à la fois en direc tion les sièges de la rangée considérée et à la fois de la rangée de devant. Le quatrième sous-ensemble 14 comporte un dispositif de captation audio. As a variant, the EPSU only comprises the third sub-assembly 13 (and not the third sub-assembly bis 13 '). In this case and preferably, the headlights 23a, 23b, 23c are arranged so as to be able to radiate both in the direction of the seats in the row in question and both in the front row. The fourth sub-assembly 14 includes an audio pickup device.
Le dispositif de captation audio 14 peut comporter au moins un microphone et de préférence au moins deux microphones 24a, 24b. Les deux microphones 24a, 24b sont par exemple agencés de part et d'autre d'un ensemble formé par les deux disposi tifs de prise d'images 21a, 21b du premier sous-ensemble 11 et le capteur de température 22 du deuxième sous-ensemble 12 et/ou les deux dispositifs de prise d'images 21a, 21b du premier sous-ensemble 11 et le capteur de température 22 du deuxième sous-ensemble 12. The audio pickup device 14 can include at least one microphone and preferably at least two microphones 24a, 24b. The two microphones 24a, 24b are for example arranged on either side of an assembly formed by the two image-taking devices 21a, 21b of the first sub-assembly 11 and the temperature sensor 22 of the second sub-assembly. assembly 12 and / or the two image-taking devices 21a, 21b of the first sub-assembly 11 and the temperature sensor 22 of the second sub-assembly 12.
Au moins l'un des microphones 24a, 24b est par exemple un microphone miniature. At least one of the microphones 24a, 24b is for example a miniature microphone.
Un traitement des informations générées par au moins les deux microphones 24a, 24b est effectué ultérieurement et permet ainsi de détecter des enregistrements une toux et/ou un éternuement potentiellement révélateur d'un passager ma lade. Ce traitement est assuré par un dispositif de traite ment de sons, via une intelligence artificielle par exemple, intégré dans le quatrième sous-ensemble 14 lui- même, dans l'EPSU ou dans le serveur central 4. Optionnellement, un signal d'alarme peut alors être généré à destination de l'équipage par exemple via l'interface de communication avion/équipage 5. A processing of the information generated by at least the two microphones 24a, 24b is carried out subsequently and thus makes it possible to detect recordings of a potentially revealing cough and / or sneezing of a passenger with sickness. This processing is provided by a sound processing device, via artificial intelligence for example, integrated in the fourth sub-assembly 14 itself, in the EPSU or in the central server 4. Optionally, an alarm signal can then be generated for the crew, for example via the aircraft / crew communication interface 5.
Le quatrième sous-ensemble 14 permet ainsi de remplir une fonction d'amélioration de la sécurité sanitaire. Préférentiellement, l'EPSU est agencée de sorte à pouvoir contrôler non seulement la rangée de sièges considérée mais également la rangée de sièges adjacente immédiatement agen cée devant. A cet effet, l'EPSU comporte un quatrième sous- ensemble bis 14' identique au quatrième sous-ensemble 14 mais agencé de sorte que le dispositif de captation audio 24a', 24b' du quatrième sous-ensemble bis 14' permette de viser la rangée de sièges adjacente immédiatement agencée devant. On assure ainsi une redondance de la surveillance des pas sagers puisque chaque rangée de siège peut être observée par deux quatrièmes sous-ensembles de deux EPSU adjacents. En cas d'existence d'un quatrième sous-ensemble bis 14', le dispositif de traitement de sons pourra être commun au qua- trième sous-ensemble 14 et au quatrième sous-ensemble bis 14'. The fourth sub-assembly 14 thus makes it possible to fulfill a function of improving health security. Preferably, the EPSU is arranged so as to be able to control not only the row of seats considered but also the adjacent row of seats immediately arranged in front. To this end, the EPSU comprises a fourth bis sub-assembly 14 'identical to the fourth sub-assembly 14 but arranged so that the audio capture device 24a', 24b 'of the fourth bis sub-assembly 14' makes it possible to target the adjacent row of seats immediately arranged in front. This ensures redundancy in the monitoring of the sager steps since each row of seats can be observed by two fourth subsets of two adjacent EPSUs. If there is a fourth sub-assembly bis 14 ', the sound processing device may be common to the fourth sub-assembly 14 and to the fourth sub-assembly bis 14'.
De préférence, tous les quatrièmes sous-ensembles 14 et sous-ensemble bis 14' du système général EPSU sont corrélés entre eux. Par exemple le dispositif de traitement de sons est le même pour tous les EPSU du système général EPSU afin de récupérer dudit système l'ensemble des informations gé nérées par les différents microphones 24a, 24b de tous les EPSU. De la sorte, ledit dispositif de traitement de sons peut détecter les toux et les éternuements dans la cabine 2 mais également générer au moins une image sonore multidi mensionnelle de la cabine 2 afin de localiser plus facile ment la source des toux et/ou éternuements et identifier le ou les passagers en cause. Preferably, all of the fourth subsets 14 and bis subsets 14 'of the general EPSU system are correlated with one another. For example, the sound processing device is the same for all the EPSUs of the general EPSU system in order to recover from said system all the information generated by the different microphones 24a, 24b of all the EPSUs. In this way, said sound processing device can detect coughs and sneezes in cabin 2 but also generate at least one multi-dimensional sound image of cabin 2 in order to more easily locate the source of coughs and / or sneezes and identify the passenger (s) involved.
Optionnellement l'EPSU comporte au moins un sous-ensemble additionnel. Par exemple ledit sous-ensemble additionnel permet de remplir une fonction qui n'est pas une fonction d'amélioration de la sécurité sanitaire. Optionally, the EPSU includes at least one additional sub-assembly. For example, said additional sub-assembly makes it possible to fulfill a function which is not a function of improving health security.
Dans le cas présent, l'EPSU comporte un cinquième sous-en semble 15 pour la communication sans fil avec l'EPSU. A cet effet, le cinquième sous-ensemble 15 comporte au moins un coupleur (tel qu'un MODEM) pour une communication sans fil avec l'EPSU selon un premier standard de communi cation. In the present case, the EPSU has a fifth sub-assembly 15 for wireless communication with the EPSU. To this end, the fifth sub-assembly 15 comprises at least one coupler (such as a MODEM) for communication. wireless with the EPSU according to a first communi cation standard.
De préférence, le cinquième sous-ensemble 15 comporte au moins deux coupleurs (tels que deux MODEM) pour une commu- nication sans fil avec l'EPSU selon au moins deux standards de communication différents, avec un coupleur par standard. Ceci permet de couvrir différents besoins en communication sans fil. Preferably, the fifth sub-assembly 15 comprises at least two couplers (such as two MODEMs) for wireless communication with the EPSU according to at least two different communication standards, with one coupler per standard. This makes it possible to cover different wireless communication needs.
Le ou les standards de communication sont par exemple choi- sis par les standards de communication suivants : Wifi, 3G, 4G, 5G, BlueTooth, Lora, Sigfox, WAIC ... The communication standard (s) are for example chosen by the following communication standards: Wifi, 3G, 4G, 5G, BlueTooth, Lora, Sigfox, WAIC ...
De préférence le ou les coupleurs sont des coupleurs radio (par exemple des MODEM radios) de sorte que la communica tion sans fil avec l'EPSU se fasse par fréquence radio (ou RF pour Radio Frequency en anglais) et donc selon un ou plusieurs standards de communication précités. Preferably, the coupler (s) are radio couplers (for example radio MODEMs) so that wireless communication with the EPSU takes place by radio frequency (or RF for Radio Frequency in English) and therefore according to one or more standards. of the aforementioned communication.
Du fait que chaque EPSU du système général EPSU comporte un cinquième sous-module 15, les différentes EPSU permettent avantageusement de créer conjointement, entre eux et avec le serveur central 4 auquel le système général EPSU est raccordé, des réseaux de communication sans fil maillés dans la cabine 2 (un réseau RF par standard de communica tion). Due to the fact that each EPSU of the general EPSU system comprises a fifth sub-module 15, the different EPSUs advantageously make it possible to jointly create, between themselves and with the central server 4 to which the general EPSU system is connected, wireless communication networks meshed in cabin 2 (one RF network per communication standard).
Du fait du nombre et de la répartition des EPSU dans la ca- bine 2, ces réseaux sont robustes aux défaillances de quelques cinquièmes sous-ensembles 15 voire de quelques EPSU. En outre, les réseaux sont de bonne qualité dans toute la cabine avion. Due to the number and distribution of EPSUs in cab 2, these networks are robust to failures of a few fifth subassemblies 15 or even a few EPSUs. In addition, the networks are of good quality throughout the aircraft cabin.
Ainsi, les réseaux sont auto-adaptatifs : la défaillance de l'un des EPSU peut en effet être compensée par les EPSU si tués dans son environnement proche. Thus, the networks are self-adapting: the failure of one of the EPSUs can in fact be compensated by the EPSUs if they are killed in its close environment.
De façon avantageuse le système général EPSU permet une très bonne couverture de l'avion 1 pour chaque réseau con sidéré sans ajout d'Unité Remplaçable en Ligne spécifique (plus connue sous l'acronyme anglais LRU pour Line Re- placeable Unit). De préférence, le système général EPSU est configuré de sorte qu'au moins un, et de préférence tous les réseaux, soit des réseaux Ad Hoc par exemple un réseau RF Ad Hoc, un réseau WANET Wireless Ad Hoc Network, un réseau MANET Mo- bile Ad Hoc Network ... Advantageously, the general EPSU system allows very good coverage of the airplane 1 for each network considered without adding a specific Line Replaceable Unit (better known by the English acronym LRU for Line Replaceable Unit). Preferably, the general EPSU system is configured so that at least one, and preferably all of the networks, are Ad Hoc networks, for example an RF Ad Hoc network, a WANET Wireless Ad Hoc Network, a MANET Mo- network. bile Ad Hoc Network ...
Le cinquième sous-module 15 peut ainsi permettre de remplir une ou plusieurs fonctions parmi les suivantes (liste non exhaustive) selon le réseau utilisé : The fifth sub-module 15 can thus make it possible to fulfill one or more functions among the following (non-exhaustive list) depending on the network used:
- la connexion d'objets (de type ordinateur portable, téléphone intelligent ou « smartphone » en anglais, écran, tablette ...ou bien encore l'interface de communication avion/équipage 5) au réseau considéré ; - the connection of objects (of the laptop, smart phone or “smartphone” type in English, screen, tablet, etc. or even the aircraft / crew communication interface 5) to the network in question;
- recevoir et distribuer des informations à une autre EPSU du système général EPSU ; chaque EPSU peut ainsi ser- vir de répéteur pour les autres EPSU ce qui permet de rendre le(s) réseau (x) considéré(s) très robuste(s) et auto-adaptatif. En effet chaque EPSU est capable de s'adap ter à l'avion 1 et notamment à son positionnement dans ce lui-ci. En particulier, chaque EPSU a un comportement dif- férent selon son positionnement dans la cabine 2 (chaque EPSU relayant de préférence une ou des informations aux différents EPSU agencés derrière lui) ; - receive and distribute information to another EPSU in the general EPSU system; each EPSU can thus serve as a repeater for the other EPSUs, which makes it possible to make the network (s) considered very robust and self-adaptive. In fact, each EPSU is capable of adapting to the airplane 1 and in particular to its positioning therein. In particular, each EPSU behaves differently depending on its positioning in the cabin 2 (each EPSU preferably relaying one or more information to the different EPSUs arranged behind it);
- fournir un ou des services personnalisés à chaque pas sager ; en effet un passager peut se connecter au serveur central 4 (capable par exemple de fournir des services in ternet et/ou des divertissements divers) via notamment, bien que non exclusivement, les réseaux de standards Wifi et Bluetooth ; - provide one or more personalized services at each step; in fact, a passenger can connect to the central server 4 (capable for example of providing internet services and / or various entertainment) via in particular, although not exclusively, the networks of Wi-Fi and Bluetooth standards;
- identifier des smartphones non positionnés en mode avion grâce notamment, bien que non exclusivement aux ré seaux de standards 3G ou 4G ou 5G ; un signal d'alarme peut alors être généré à destination de l'équipage par exemple via l'interface de communication avion/équipage 5 ; - identify smartphones not positioned in airplane mode, in particular, although not exclusively, using standard 3G or 4G or 5G networks; an alarm signal can then be generated for the crew, for example via the aircraft / crew communication interface 5;
- servir de Station de Transmission de Base (plus connue sous l'acronyme anglais de BTS pour « Base Transceiver Sta- tion ») en cas d'autorisation d'utilisation à bord des té léphones mobiles (smartphones ou non) ; - serve as a Base Transmission Station (better known by the English acronym of BTS for "Base Transceiver Sta- tion ”) in the event of authorization of use on board of mobile telephones (smartphones or not);
- identifier une ou des cartes d'embarquement ; en ef fet, la plupart des cartes d'embarquement sont aujourd'hui chargées sur les smartphones : les EPSU peuvent ainsi transmettre ces identifications au serveur central 4 ce qui permet par exemple de tracer un changement éventuel de sièges entre passagers, de vérifier la cohérence de l'em barquement de l'avion ... ; - interfacer des Concentrateurs de Données sans Fil de l'avion 1 (plus connus sous l'acronyme anglais de RDC pour « Remote Data Concentrator ») ; - identify one or more boarding passes; in fact, most boarding cards are now loaded on smartphones: the EPSUs can thus transmit these identifications to the central server 4 which makes it possible, for example, to trace a possible change of seats between passengers, to check the consistency boarding the plane ...; - interfacing the Wireless Data Concentrators of aircraft 1 (better known by the acronym of RDC for “Remote Data Concentrator”);
- rapatrier des informations acquises localement par un ou des RDC au niveau du serveur central ; par exemple bien que non exclusivement par le réseau de standard WAIC ; - repatriate information acquired locally by one or more RDCs at the level of the central server; for example although not exclusively by the WAIC standard network;
- etc. - etc.
De préférence, l'EPSU comporte un ou plusieurs sous-en sembles additionnels comme par exemple (liste non exhaus tive): a)Un sous-ensemble d'éclairages individuels 16 afin d'associer un éclairage à chaque siège de la rangée de sièges considéré. De préférence l'intensité lumineuse des éclairages est réglable de manière individuelle. Les éclai rages sont des projecteurs et/ou des LEDS et/ou miniatures. Les éclairages travaillent de préférence dans le domaine visible et sont ainsi des éclairages RVB. De préférence, le spectre de couleurs des éclairages est suffisamment large pour que les éclairages soient adaptés aux différentes phases de vol (en particulier lorsque la cabine 2 est éteinte et lorsque la cabine 2 est allumée). b)Un sous-ensemble de communication audio 17. Ledit sous-ensemble comporte par exemple au moins un haut-parleur et de préférence au moins deux haut-parleurs avec un pre mier haut-parleur dirigé vers la rangée de siège considéré et un deuxième haut-parleur dirigé vers la rangée de siège avant. Au moins l'un des haut-parleurs est de préférence miniature. c)Un sous-ensemble de mesure de la température 18 am biante de la cabine 2. Ledit sous-ensemble comporte par exemple au moins un capteur de température tel qu'un ther- mocouple ; et de préférence au moins deux capteurs de tem pératures avec un premier capteur dirigé vers la rangée de siège considéré et un deuxième capteur dirigé vers la ran gée de siège avant. En option ledit sous-ensemble comporte quatre capteurs de température avec deux capteurs dirigés vers la rangée de siège considéré et deux capteurs dirigés vers la rangée de siège avant. d)Un sous-ensemble d'affichage d'informations 19 à des tination du passager ou des passagers et/ou de l'équipage. Ledit sous-ensemble est préférentiellement également con- formé en une interface de commande par un ou les passagers de la rangée. Typiquement ledit sous-ensemble comporte au moins un écran. De préférence, l'écran est en couleurs. L'écran peut être tactile. Par exemple un passager peut ap peler un membre de l'équipage via ledit écran. e)Un sous-ensemble d'auto-adressage de l'EPSU au serveur central 4. Ceci permettra au serveur central 4 de recon naître l'EPSU considérée et/ou d'en connaître son état opé rationnel et/ou de la reconfigurer. Optionnellement ledit sous-ensemble intègre un Dispositif de Test Intégré (plus connu sous l'acronyme anglais BITE pour « Built In TestPreferably, the EPSU comprises one or more additional sub-sections such as for example (non-exhaustive list): a) A sub-assembly of individual lights 16 in order to associate lighting with each seat in the row of seats considered. Preferably the light intensity of the lights is individually adjustable. The lights are projectors and / or LEDs and / or miniatures. The lights preferably work in the visible range and are thus RGB lights. Preferably, the color spectrum of the lights is sufficiently wide for the lights to be adapted to the different phases of flight (in particular when the cabin 2 is off and when the cabin 2 is on). b) An audio communication sub-assembly 17. Said sub-assembly comprises for example at least one loudspeaker and preferably at least two loudspeakers with a first loudspeaker directed towards the row of seats in question and a second loudspeaker directed to the front seat row. At least one of the speakers is preferably miniature. c) A sub-assembly for measuring the 18-room temperature of the cabin 2. Said sub-assembly comprises for example at least one temperature sensor such as a thermocouple; and preferably at least two temperature sensors with a first sensor directed towards the row of seat in question and a second sensor directed towards the row of the front seat. As an option, said sub-assembly comprises four temperature sensors with two sensors directed towards the row of seat in question and two sensors directed towards the front row of seats. d) An information display sub-assembly 19 for the purpose of the passenger or passengers and / or the crew. Said sub-assembly is preferably also formed into a control interface by one or more passengers in the row. Typically said sub-assembly comprises at least one screen. Preferably, the screen is in color. The screen can be touch-sensitive. For example, a passenger can call a member of the crew via said screen. e) A self-addressing subset of the EPSU to the central server 4. This will allow the central server 4 to recognize the EPSU in question and / or to know its operational state and / or to reconfigure it. . Optionally, said sub-assembly incorporates an Integrated Test Device (better known by the English acronym BITE for "Built In Test
Equipment ») afin que le serveur central 4 connaisse l'état opérationnel de l'EPSU considérée. Chaque EPSU du système général EPSU étant munie d'un tel sous-ensemble, le serveur central 4 peut ainsi générer une cartographie précise du système général EPSU. f) Un sous-ensemble d'appel du personnel navigant 20. Le dit sous-ensemble peut comporter au moins un bouton pous soir assigné à chaque siège. Equipment ') so that the central server 4 knows the operational state of the EPSU in question. Each EPSU of the general EPSU system being provided with such a sub-assembly, the central server 4 can thus generate a precise map of the general EPSU system. f) A flight crew call sub-assembly 20. Said sub-assembly may include at least one push button assigned to each seat.
On va à présent expliciter le raccordement du système géné ral EPSU au serveur central 4. We will now explain the connection of the general EPSU system to the central server 4.
Si les EPSU peuvent communiquer entre elles via le ou les réseaux de communications sans fil qui ont été décrits, en revanche le système général EPSU est connecté au serveur central 4 par l'intermédiaire d'une liaison filaire. If the EPSUs can communicate with each other via the wireless communications networks which have been described, on the other hand the general EPSU system is connected to the central server 4 via a wired link.
En référence aux figures 3 et 4, de préférence les EPSU de la (ou des rangées) les plus proches du serveur central 4 sont physiquement raccordées par liaison filaire audit ser veur central 4. Usuellement le serveur central 4 est agencé entre la cabine 2 et le poste de pilotage : dans ce cas les EPSU les plus proches sont celles associées à la première rangée avant de chaque colonne de siège de la cabine 2. Ici il y a deux rangées avant de sièges et donc deux EPSU (no tées EPSU avant par la suite) physiquement raccordées de manière filaire au serveur central 4. Referring to Figures 3 and 4, preferably the EPSUs of the (or rows) closest to the central server 4 are physically connected by wire link to said central server 4. Usually the central server 4 is arranged between the cabin 2 and the cockpit: in this case the closest EPSUs are those associated with the first front row of each seat column in cabin 2. Here there are two front rows of seats and therefore two EPSUs (front EPSU numbers by following) physically wired to the central server 4.
Les autres EPSU du système général EPSU communiquent quant à elles avec les deux EPSU avant via le ou les réseaux sans fil pour pouvoir interagir avec le serveur central 4. Ainsi seules les deux EPSU avant communiquent directement avec le serveur central 4, les autres EPSU communiquant avec lui de manière indirecte via les deux EPSU avant. Préférentiellement la connexion des deux EPSU avant au ser veur central 4 est assurée via au moins un équipement de sécurité informatique de type pare-feu ou « diode Ethernet » (dans le cas d'une liaison filaire Ethernet). L'équipe ment de sécurité est par exemple une Interface de Communi- cation Sécurisée 6 (plus connu sous l'acronyme anglais de SCI pour « Secure Communication Interface ») et/ou Diode Monde Ouvert 7 (plus connu sous l'acronyme anglais d'OWD pour « Open World Device (or Diode) »). The other EPSUs of the general EPSU system communicate with the two front EPSUs via the wireless network (s) in order to be able to interact with the central server 4. Thus only the two front EPSUs communicate directly with the central server 4, the other EPSUs communicating with him indirectly via the two front EPSUs. Preferably, the connection of the two front EPSUs to the central server 4 is provided via at least one computer security device of the firewall or “Ethernet diode” type (in the case of a wired Ethernet link). The security team is for example a Secure Communication Interface 6 (better known by the acronym of SCI for “Secure Communication Interface”) and / or Open World Diode 7 (better known by the English acronym d 'OWD for "Open World Device (or Diode)").
De la sorte, on protège le serveur central 4 d'éventuelles cyber-attaques provenant d'un ou de passagers utilisant le (s) réseau (x) de communication sans fil assuré(s) entre autres par le système général d'EPSU. In this way, the central server 4 is protected from possible cyber-attacks originating from one or more passengers using the wireless communication network (s) provided, inter alia, by the general EPSU system.
Le système général EPSU est ainsi isolé du reste de l'ins tallation avion, particulièrement de ses fonctions cri tiques. Optionnellement, la connexion des deux EPSU avant au ser veur central 4 est une connexion filaire Ethernet et par exemple une connexion filaire 100 mégabits Ethernet ou 1 gigabit Ethernet ou 10 gigabits Ethernet. A cet effet, au moins les deux EPSU avant sont munies d'une interface de bus numérique pour la connexion filaire au serveur central 4 telle qu'une interface Ethernet et par exemple une inter face 100 mégabits Ethernet ou 1 gigabit Ethernet ou 10 gi gabits Ethernet. De préférence, et comme déjà indiqué, toutes les EPSU sont identiques de sorte que toutes les EPSU comportent ici une interface de bus numérique pour une connexion filaire quand bien même ladite interface n'est pas utilisée. The general EPSU system is thus isolated from the rest of the aircraft installation, particularly from its critical functions. Optionally, the connection of the two front EPSUs to the central server 4 is a wired Ethernet connection and for example a wired 100 megabit Ethernet or 1 gigabit Ethernet or 10 gigabit Ethernet connection. To this end, at least the two front EPSUs are provided with a digital bus interface for the wired connection to the central server 4 such as an Ethernet interface and for example a 100 megabit Ethernet or 1 gigabit Ethernet or 10 gigabit Ethernet interface or 10 gi masks. Ethernet. Preferably, and as already indicated, all the EPSUs are identical so that all the EPSUs here include a digital bus interface for a wired connection even though said interface is not used.
Ceci évite à avoir à développer différents types d'EPSU pour un même avion 1. This avoids having to develop different types of EPSU for the same aircraft 1.
Selon un autre aspect, les EPSU sont configurées pour être compatibles avec les réseaux d'alimentation électrique usuellement en place dans un avion 1. Les EPSU sont ainsi configurées pour être alimentées via les réseaux 115 Volts (en courant alternatif) et 28 Volts (en courant continu) déjà présents dans l'avion. According to another aspect, the EPSUs are configured to be compatible with the electrical supply networks usually in place in an airplane 1. The EPSUs are thus configured to be supplied via the 115 Volts (alternating current) and 28 Volts (in alternating current) networks. direct current) already present in the aircraft.
Ceci facilite l'implantation des EPSU dans l'avion 1. This facilitates the installation of the EPSUs in the airplane 1.
Le câblage électrique des EPSU est par ailleurs simple : seul le raccordement aux réseaux d'alimentation électrique est nécessaire au fonctionnement de chaque EPSU. Les EPSU sont ainsi raccordées électriquement à l'avion 1 que par les réseaux de bord 115 Volts (en courant alternatif) et/ou 28 Volts (en courant continu). The electrical wiring of the EPSUs is also simple: only the connection to the electrical supply networks is necessary for the operation of each EPSU. The EPSUs are thus electrically connected to the airplane 1 only by the on-board networks 115 volts (in alternating current) and / or 28 volts (in direct current).
On a ainsi décrit des EPSU contribuant à la sécurité sani- taire des personnes à bord de l'avion 1. Lesdits EPSU per mettent en effet de : EPSUs have thus been described which contribute to the health safety of persons on board airplane 1. Said EPSUs in fact make it possible to:
- mesurer les températures corporelles des passagers,- measure the body temperatures of passengers,
- de détecter des éternuements et/ou des toux, - detect sneezing and / or coughing,
- de vérifier le comportement des passagers vis-à-vis des règles de sécurité sanitaire, et - de contribuer à la désinfection de la cabine de l'avion- to check the behavior of passengers with regard to health safety rules, and - contribute to the disinfection of the aircraft cabin
1. 1.
De façon avantageuse, les EPSU peuvent être implantées dans un avion 1 en remplacement d'ex-PSU de l'art antérieur. II n'y a ainsi pas besoin de modifier la structure de l'avion 1 pour y implanter les EPSU. En outre, on profite avantageusement des emplacements des ex-PSU et de leurs in terfaces de câblage déjà en place pour implanter les EPSU ce qui facilite l'agencement des EPSU dans l'avion 1. Les EPSU sont ainsi configurées et dimensionnées de sorte à être compatibles « taille forme fonction » (plus connu sous l'acronyme anglais 3F pour « Fit Form Function »), c'est-à- dire installables dans un avion 1 existant sans interven tion majeure. De plus les EPSU permettent d'assurer des fonctions habi tuelles additionnelles à la sécurité sanitaire des per sonnes à bord de l'avion 1. Advantageously, the EPSUs can be installed in an aircraft 1 as a replacement for ex-PSUs of the prior art. There is thus no need to modify the structure of the airplane 1 in order to install the EPSUs there. In addition, advantageously advantage is taken of the locations of the ex-PSUs and their cabling interfaces already in place to install the EPSUs, which facilitates the arrangement of the EPSUs in the airplane 1. The EPSUs are thus configured and dimensioned so as to be “size form function” compatible (better known by the English acronym 3F for “Fit Form Function”), that is to say installable in an existing aircraft 1 without major intervention. In addition, the EPSUs make it possible to perform additional usual functions for the health safety of persons on board the aircraft 1.
En particulier les EPSU permettent de garantir une couver ture de communication sans fil très complète dans la cabine 2. In particular, the EPSUs make it possible to guarantee very complete wireless communication coverage in cabin 2.
En outre, la consommation électrique des EPSU est relative ment raisonnable. In addition, the power consumption of EPSUs is relatively reasonable.
Bien entendu l'invention n'est pas limitée au mode de réa lisation décrit et on pourra y apporter des variantes de réalisation sans sortir du cadre de l'invention. Of course, the invention is not limited to the embodiment described and it is possible to provide variant embodiments without departing from the scope of the invention.
En particulier, bien qu'ici l'invention soit mise en place dans un avion, l'invention pourra être implantée de manière générale dans tout autre véhicule de transport qu'il soit aérien, ferroviaire, routier ... Bien qu'ici le véhicule de transport soit désinfecté sans intervention humaine, on pourra envisager que le véhicule de transport soit désinfecté et/ou nettoyé par l'invention avant qu'une équipe de maintenance réalise un deuxième net toyage (qui sera donc plus léger que ce qui aurait été né- cessaire sans l'invention). In particular, although here the invention is implemented in an aircraft, the invention can be implemented in general in any other transport vehicle whether it is air, rail, road ... Although here the transport vehicle is disinfected without human intervention, it is possible to envisage that the transport vehicle is disinfected and / or cleaned by the invention before a maintenance team carries out a second cleaning (which will therefore be lighter than what would have been required without the invention).
Un même sous-ensemble pourra être configuré pour pouvoir remplir davantage de fonctions que ce qui a été indiqué :The same sub-assembly can be configured to be able to perform more functions than indicated:
- Au moins deux sous-ensembles précités pourront être fusionnés entre eux pour former un seul sous-ensemble rem plissant les fonctions des deux sous-ensembles initiaux. - Typiquement un sous-ensemble pourra comprendre deux dispositifs de prise d'images infrarouges permettant d'éta blir une vision stéréoscopique infrarouge : le sous-en semble pourra ainsi remplir à la fois le rôle du premier sous-ensemble et du deuxième sous-ensemble qui ont été dé- crits précédemment. - At least two aforementioned sub-assemblies may be merged with one another to form a single sub-assembly fulfilling the functions of the two initial sub-assemblies. - Typically a sub-assembly could include two infrared image-taking devices making it possible to establish an infrared stereoscopic vision: the sub-assembly could thus fulfill both the role of the first sub-assembly and of the second sub-assembly which have been described previously.
- Le premier sous-ensemble pourra également être uti lisé, en remplacement ou en complément de la surveillance du respect des gestes barrières par les passagers, pour permettre d'identifier un ou des passagers et/ou de compter des passagers. En effet, la vision stéréoscopique générée par chaque premier sous-ensemble et le regroupement des in formations correspondantes sur un serveur central permettra d'assurer automatiquement le comptage des passagers. - The first sub-assembly could also be used, replacing or complementing the monitoring of compliance with barrier gestures by passengers, to make it possible to identify one or more passengers and / or to count passengers. Indeed, the stereoscopic vision generated by each first sub-assembly and the grouping of the corresponding information on a central server will automatically ensure the counting of passengers.
- On pourra également détecter une personne qui éternue et/ou qui tousse (comme pour le quatrième sous-ensemble) via le premier sous-ensemble et le traitement des images générées par celui-ci. - It is also possible to detect a person who sneezes and / or who coughs (as for the fourth subset) via the first subset and the processing of the images generated by it.
A contrario un sous-ensemble pourra remplir moins de fonc tions que ce qui a été indiqué. Par exemple si l'invention comporte un sous-ensemble pour la communication sans fil, ledit sous-ensemble pourra ne relayer qu'un seul standard de communication sans fil comme par exemple le standard 3G. Le premier sous-ensemble pourra par exemple ne pas partici per à la mesure de la température corporelle des passages. En outre l'invention pourra comprendre davantage ou moins de sous-ensemble que ce qui a été indiqué. Par ailleurs les sous-ensembles pourront être différents de ce qui a été in diqué par exemple en fonction des souhaits des compagnies de transport considérées. Par exemple on pourra associer un capteur de température à chaque passager au lieu d'associer un capteur de température aux différents passagers d'une même rangée de sièges. Conversely, a sub-assembly may fulfill fewer functions than what has been indicated. For example, if the invention comprises a sub-assembly for wireless communication, said sub-assembly could only relay a single wireless communication standard such as for example the 3G standard. The first subset may for example not participate in the measurement of the body temperature of the passages. In addition, the invention may include more or less sub-assembly than what has been indicated. Furthermore, the sub-assemblies may be different from what has been indicated, for example depending on the wishes of the transport companies considered. For example, we can associate a temperature sensor with each passenger instead of associating a temperature sensor with the different passengers of a same row of seats.
Selon une variante simplifiée appliquée à un avion, l'EPSU sera une ex-PSU dans laquelle les éclairages standards se ront remplacés, selon un mode de réalisation particulier de l'invention, par des éclairages à double sources lumineuses (dans le domaine du visible et dans le domaine de l'ultra violet) permettant tout à la fois d'assurer la fonction d'éclairage individuel et de nettoyage par projection de rayons ultraviolets du siège associé. On profitera ainsi avantageusement des emplacements des éclairages standards des ex-PSU de l'art antérieur dédiés à chaque siège. According to a simplified variant applied to an airplane, the EPSU will be an ex-PSU in which the standard lighting will be replaced, according to a particular embodiment of the invention, by lighting with dual light sources (in the visible field. and in the field of ultra violet) making it possible at the same time to ensure the function of individual lighting and cleaning by projection of ultraviolet rays of the associated seat. Advantageously, use will thus be made of the locations of the standard lighting of the ex-PSUs of the prior art dedicated to each seat.
En remplacement ou en complément, on pourra tirer profit des commandes « no - smoking » et/ou des voyants « no - smoking » des ex-PSU devenus inutiles pour implanter au moins en partie l'invention. Ainsi le troisième sous-en semble pourra être en partie ou en totalité agencé dans la zone réservée au voyant « no-smoking » et/ou la commande « no smoking » de l'interface de communication avion/équi- page pourra être employée pour commander lesdits troisièmes sous-ensembles. As a replacement or in addition, it will be possible to take advantage of the “no-smoking” commands and / or the “no-smoking” indicators of the ex-PSUs which have become useless for at least partially implementing the invention. Thus the third sub-assembly could be partially or totally arranged in the zone reserved for the “no-smoking” indicator light and / or the “no smoking” command of the aircraft / crew communication interface could be used for order said third sub-assemblies.
D'autres types de projecteurs que des projecteurs UVC pour ront être employés dans le troisième sous-ensemble. L'invention pourra être davantage configurée pour limiter les cyber-attaques de la part de passagers que ce qui a été indiqué au serveur central par exemple en incorporant un ou des éléments de conception et de justification, un ou des isolations physiques via des équipements type pare-feu et autres « diodes Ethernet » ... Other types of projectors than UVC projectors may be used in the third sub-assembly. The invention can be configured more to limit cyber attacks from passengers than what has been indicated to the central server, for example by incorporating one or more design and justification elements, one or more physical isolations via typical equipment. firewalls and other "Ethernet diodes" ...
L'invention pourra également s'adapter à la situation en cours et activer/désactiver au moins l'un de ses sous-en sembles en conséquence (par exemple interdiction d'utilisa tion des ultraviolets pendant le transport du fait de la présence d'au moins un passager dans le véhicule ; inter diction d'utiliser le(s) réseau (x) de communication sans fil durant les phases d'atterrissages et de décollages d'un avion ...). Dans le cas d'un avion, l'invention pourra s'ap puyer sur les signaux discrets TOR (Tout Ou Rien) utilisés par ailleurs pour le WEFA (Wireless Evolution For ACMS), et indiquant l'état opérationnel de l'avion (sol ou vol), pour activer/désactiver un ou plusieurs de ses sous-ensembles.The invention can also adapt to the current situation and activate / deactivate at least one of its sub-sets as a consequence (for example prohibition of the use of ultraviolet rays during transport due to the presence of at least one passenger in the vehicle; prohibition to use the wireless communication network (s) during the landing and take-off phases of a airplane ...). In the case of an airplane, the invention may be based on the discrete TOR (All Or Nothing) signals used elsewhere for WEFA (Wireless Evolution For ACMS), and indicating the operational state of the airplane ( ground or flight), to activate / deactivate one or more of its sub-assemblies.
La désactivation/activation pourra se faire à un niveau plus général et par exemple au niveau du système général EPSU et/ou du serveur central. The deactivation / activation can be done at a more general level and for example at the level of the general EPSU system and / or of the central server.
Le serveur central pourra être redondé, le système général EPSU étant alors connecté de manière correspondante au ser veur redondé et redondant. The central server may be redundant, the general EPSU system then being connected in a corresponding manner to the redundant and redundant server.
