Description

SYSTEME EMBARQUE ET PROCEDE DE DIFFUSION D'INFORMATION DANS UN VEHICULE ONBOARD SYSTEM AND METHOD FOR DIFFUSION OF INFORMATION IN A VEHICLE
La présente invention a pour objet un système embarqué et un procédé de diffusion d'information dans un véhicule. Elle trouve notamment son application aux systèmes de diffusion d'information embarqués dans un train ou un bus, pour l'information des voyageurs.The present invention relates to an embedded system and a method of broadcasting information in a vehicle. It finds particular application to information dissemination systems embedded in a train or a bus for the information of travelers.
On connaît des systèmes de diffusion d'information sonore embarqués dans un train qui comprennent un serveur d'information avec une base de données, et des moyens de diffusion d'informations préenregistrées dans la base de données. Généralement, ces systèmes comprennent également une ligne de sonorisation permettant de diffuser les informations sonores, sur laquelle le personnel d'exploitation du train peut directement intervenir par exemple par l'intermédiaire d'un combiné téléphonique, pour diffuser des messages vocaux spécifiques.Embedded sound information broadcasting systems are known in a train which comprise an information server with a database, and means for broadcasting information prerecorded in the database. Generally, these systems also include a sound line for broadcasting the sound information, on which the operating staff of the train can directly intervene for example via a telephone handset, to broadcast specific voice messages.
Ces systèmes diffusent donc des informations, sonores ou visuelles, préenregistrées. L'activation et le choix de l'information à diffuser sont ainsi effectués par le personnel d'exploitation du train, ou encore automatiquement par localisation GPS et odométrique. Cependant, ce type de système ne permet pas de diffuser des informations de sources multiples et de formats multiples. En outre, il nécessite de fréquentes interventions sur le serveur d'information, pour des mises à jour de logiciels, notamment en cas de changement de format, ou encore pour des mises à jour de données (changement de trajet par exemple).These systems broadcast information, sound or visual, prerecorded. The activation and the choice of the information to be broadcast are thus carried out by the operating personnel of the train, or automatically by GPS and odometric location. However, this type of system does not allow to broadcast information from multiple sources and multiple formats. In addition, it requires frequent interventions on the information server, for software updates, especially in case of format change, or for data updates (path change for example).
En effet, les bases de données et les différents fichiers nécessaires sont mémorisés dans des serveurs installés de façon permanente à bord. Ces serveurs nécessitent donc des mises à jour et maintenance périodiques, avec des retours en atelier de maintenance. En outre, tous les matériels sont différents et spécifique à chaque ligne de transport, et/ou à chaque réseau de transport. Le problème qui se pose alors est donc de disposer d'un système embarqué et d'un procédé de diffusion d'information dans un véhicule qui évite d'avoir à se rendre en un lieu fixe pour diffuser l'information, et qui permette de diffuser de l'information à partir de données de sources et de formats multiples, de sorte que, indépendamment du type de matériel de transport, la ligne de transport, et/ou le réseau de transport, le système de l'invention assure l'interopérabilité entre des réseaux et/ou des matériels et/ou des lignes de transport différents.Indeed, the databases and the various necessary files are stored in servers permanently installed on board. These servers therefore require periodic updates and maintenance, with returns to the maintenance workshop. In addition, all materials are different and specific to each transmission line, and / or each transmission network. The problem then is to have an embedded system and a method of disseminating information in a vehicle that avoids having to go to a fixed location to disseminate information, and that allows to disseminate information from data from multiple sources and formats so that, regardless of the type of transport equipment, the transmission line, and / or the transmission network, the system of the invention provides interoperability between networks and / or different equipment and / or transmission lines.
L'objet de l'invention est donc d'apporter une solution au problème précité parmi d'autres problèmes.The object of the invention is therefore to provide a solution to the aforementioned problem among other problems.
L'invention se rapporte donc, selon un premier aspect, à un système de diffusion d'information embarqué dans un véhicule, notamment pour informer des voyageurs dans un train ou dans un bus, qui comprend des moyens de diffusion d'information. De façon caractéristique, le système comprend en outre un dispositif de couplage de données s'interfaçant par voie de préférence non filaire avec au moins un dispositif individuel de communication.The invention thus relates, according to a first aspect, to a system for broadcasting information embedded in a vehicle, in particular for informing passengers in a train or on a bus, which comprises means for broadcasting information. Typically, the system further comprises a data coupling device interfacing by preferably non-wired with at least one individual communication device.
Ce dispositif individuel de communication envoie ses instructions et les informations à diffuser au dispositif de couplage de données. Ce dernier contrôle les moyens de diffusion d'information.This individual communication device sends its instructions and the information to be broadcast to the data coupling device. The latter controls the means of disseminating information.
Ainsi, il n'est plus nécessaire de se rendre en un lieu fixe pour diffuser l'information. Quelque soit la localisation du dispositif individuel de communication, il est en mesure de communiquer avec le dispositif de couplage de données qui contrôle la diffusion de l'information par les moyens de diffusion de l'information.Thus, it is no longer necessary to go to a fixed location to disseminate information. Whatever the location of the individual communication device, it is able to communicate with the data coupling device that controls the dissemination of information by the information dissemination means.
Ainsi encore, les interventions de mises à jour logicielles sur le dispositif de couplage de données peuvent être directement effectuées par le dispositif individuel de communication sans nécessiter d'intervention à bord du véhicule. En outre, le dispositif de couplage de données, avec un minimum d'intelligence, permet l'interfaçage et la diffusion de l'information à partir de données de sources et de formats multiples.Again, the software updates interventions on the data coupling device can be directly performed by the individual communication device without requiring intervention on board the vehicle. In addition, the data coupling device, with a minimum of intelligence, allows the interfacing and dissemination of information from data from multiple sources and formats.
De la sorte, indépendamment du type de matériel de transport, la ligne de transport, et/ou le réseau de transport, le système de l'invention assure l'interopérabilité entre des réseaux et/ou des matériels et/ou des lignes de transport différents.In this way, regardless of the type of transport equipment, the transmission line, and / or the transmission network, the system of the invention ensures interoperability between networks and / or equipment and / or transmission lines. different.
Dans une première variante de réalisation, le dispositif de couplage de données comprend un module de communication de préférence non filaire par lequel il reçoit ses instructions et l'information à diffuser, et au moins une sortie vers une ligne de diffusion d'information reliée aux moyens de diffusion d'information.In a first variant embodiment, the data coupling device comprises a preferably non-wired communication module by which it receives its instructions and the information to be broadcast, and at least one output to an information transmission line connected to the means of disseminating information.
Dans une autre variante de réalisation, éventuellement en combinaison avec la précédente, le dispositif de couplage de données comprend une unité logique d'aiguillage de l'information à diffuser vers la ou les sorties. Le dispositif de couplage de données comprend un module de contrôle de défaut apte à communiquer avec l'unité logique d'aiguillage de l'information.In another variant embodiment, possibly in combination with the previous one, the data coupling device comprises a logical unit for routing the information to be broadcast to the output (s). The data coupling device comprises a fault control module able to communicate with the logical unit for routing the information.
De préférence, le dispositif individuel de communication comprend une base de données d'information à diffuser. Alternativement, le système comprend un serveur d'information apte à communiquer par voie de préférence non filaire avec le dispositif individuel de communication pour lui transmettre des informations à diffuser.Preferably, the individual communication device comprises an information database to be broadcast. Alternatively, the system comprises an information server capable of communicating, preferably wirelessly, with the individual communication device to transmit information to be broadcast.
Ainsi, les interventions de mises à jour logicielles ou de données sur le serveur peuvent être directement effectuées par le dispositif individuel de communication sans nécessiter d'intervention à bord du véhicule.Thus, the interventions of software updates or data on the server can be directly performed by the individual communication device without requiring intervention on board the vehicle.
L'invention se rapporte également, selon un deuxième aspect, à un véhicule, notamment un train ou un bus, équipé du système de diffusion d'information embarqué tel que présenté ci-dessus.The invention also relates, according to a second aspect, to a vehicle, in particular a train or a bus, equipped with the on-board information transmission system as presented above.
De préférence, le véhicule est composé d'au moins deux voitures, et le système de diffusion d'information embarqué comprend un serveur d'information. Celui-ci peut être situé dans une première voiture et le dispositif de couplage de données est alors situé dans la même ou une autre voiture. De préférence, chaque voiture est équipée d'un répéteur d'information par exemple par voie non filaire.Preferably, the vehicle is composed of at least two cars, and the embedded information broadcast system comprises an information server. This one can be located in a first car and the data coupling device is then located in the same or another car. Preferably, each car is equipped with an information repeater for example by non-wired way.
De préférence également, le serveur d'information est connecté à un récepteur satellite.Also preferably, the information server is connected to a satellite receiver.
L'invention se rapporte enfin, selon un troisième aspect, à un procédé de diffusion d'information dans un véhicule, notamment pour informer des voyageurs dans un train ou dans un bus.The invention finally relates, in a third aspect, to a method of broadcasting information in a vehicle, in particular for informing passengers on a train or on a bus.
Le véhicule est muni de moyens de diffusion d'information, et d'un dispositif de couplage de données s'interfaçant de préférence par voie non filaire avec au moins un dispositif individuel de communication duquel il reçoit ses instructions et les informations à diffuser.The vehicle is provided with information dissemination means, and a data coupling device preferably interfaced by non-wired means with at least one individual communication device from which it receives its instructions and the information to be broadcast.
De façon caractéristique, le procédé comprend une étape d'envoi par le dispositif individuel de communication d'un ordre de diffusion d'une information à destination du dispositif de couplage de données, et une étape d'aiguillage par le dispositif de couplage de données de l'information à diffuser vers les moyens de diffusion d'information.Typically, the method comprises a step of sending by the individual communication device an information broadcast command to the data coupling device, and a routing step by the data coupling device. information to be disseminated to the means of disseminating information.
Dans une première variante de mise en œuvre, le dispositif de couplage de données envoie au dispositif individuel de communication une information sur son état.In a first implementation variant, the data coupling device sends the individual communication device information on its state.
Dans une autre variante de mise en œuvre, éventuellement en combinaison avec la précédente, l'information diffusée par les moyens de diffusion d'information est une information sonore et/ou visuelle.In another implementation variant, possibly in combination with the previous one, the information broadcast by the information dissemination means is sound and / or visual information.
D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement et de manière complète à la lecture de la description ci- après des variantes préférées de réalisation, lesquelles sont données à titres d'exemples non limitatifs, et en référence aux figures annexées suivantes. - figure 1 : représente schématiquement un exemple du système embarqué de diffusion d'information,Other features and advantages of the invention will appear more clearly and completely on reading the following description of the preferred embodiments, which are given by way of non-limiting examples, and with reference to the following appended figures. .

- figure 2 : représente schématiquement un dispositif de couplage de données du système embarqué de diffusion d'information de la figure 1 .FIG. 2 schematically represents a data coupling device of the on-board information dissemination system of FIG. 1.
La figure 1 représente schématiquement un exemple de système embarqué de diffusion d'information dans un train comprenant deux voitures 9 et 10.FIG. 1 schematically represents an example of an on-board information transmission system in a train comprising two cars 9 and 10.
Dans la voiture 9 est installé un serveur d'information 2, qui peut éventuellement être couplé à un récepteur satellite 12 équipé d'une antenne satellite 13 en vue d'une acquisition de données transmises par les satellites 14.In the car 9 is installed an information server 2, which may optionally be coupled to a satellite receiver 12 equipped with a satellite antenna 13 for acquisition of data transmitted by the satellites 14.
Le train est équipé d'une ligne de diffusion d'information 8, généralement sonore mais qui peut éventuellement être visuelle. Cette ligne 8 transporte de façon connue d'une voiture à l'autre les informations à diffuser. La diffusion est réalisée par des moyens de diffusion d'information 3, par exemple des haut-parleurs 3 dans le cas d'une information sonore ou des dispositifs d'affichage dans le cas d'une information visuelle. Chaque voiture 9 et 10 est équipée d'un répéteur 1 1 , qui communique notamment avec le serveur 2, et éventuellement avec des dispositifs d'affichage 15. Les communications sont de préférences non filaires, par exemple de type « Wifi ».The train is equipped with an information broadcast line 8, generally sound but which may possibly be visual. This line 8 transports in a known manner from one car to another the information to be broadcast. The diffusion is carried out by information diffusion means 3, for example loudspeakers 3 in the case of sound information or display devices in the case of visual information. Each car 9 and 10 is equipped with a repeater 1 1, which communicates in particular with the server 2, and possibly with display devices 15. The communications are preferably non-wired, for example of the "Wifi" type.
Sur la ligne de diffusion d'information 8 est placé un dispositif de couplage de données 4. Dans l'exemple représenté à la figure 1 , ce dispositif de couplage de données 4 se trouve dans la voiture 9, donc la même voiture que celle dans laquelle se trouve le serveur 2. Toutefois, il pourrait tout aussi bien se trouver dans la voiture 10.On the information broadcast line 8 is placed a data coupling device 4. In the example shown in FIG. 1, this data coupling device 4 is in the car 9, so the same car as that in which is the server 2. However, it could as well be in the car 10.
Ce dispositif de couplage de données 4 s'interface avec le serveur 2, ainsi qu'avec un ou plusieurs dispositifs individuels de communication 5, par voie non filaire, par exemple de type « Wifi ». Ces dispositifs individuels de communication 5 peuvent être par exemple du type assistant personnel numérique, ou tout autre dispositif portable intelligent.This data coupling device 4 interfaces with the server 2, as well as with one or more individual communication devices 5, by non-wired means, for example of the "Wifi" type. These individual communication devices 5 may be for example digital personal assistant type, or any other intelligent portable device.
Le dispositif individuel de communication 5 envoie des instructions au dispositif de couplage de données 4.The individual communication device 5 sends instructions to the data coupling device 4.
Il peut s'agir de l'envoi d'un ordre de diffusion d'une information qui sera ensuite aiguillée par le dispositif de couplage de données 4 vers les moyens de diffusion d'information 3.This may be the sending of an order of diffusion of information which will then be directed by the data coupling device 4 to the information dissemination means 3.

Le dispositif de couplage de données 4 reçoit ses instructions et l'information à diffuser par ce module de communication 6. Le dispositif de couplage de données 4 comprend au moins une sortie 7 vers la ligne de diffusion d'information 8 reliée aux moyens de diffusion d'information 3, tel qu'expliqué plus haut en référence à la figure 1 .The data coupling device 4 receives its instructions and the information to be broadcast by this communication module 6. The data coupling device 4 comprises at least one output 7 to the information broadcast line 8 connected to the broadcasting means information 3, as explained above with reference to Figure 1.
Dans l'exemple représenté à la figure 2, deux sorties 7 sont reliées à la ligne de diffusion d'information 8 de la figure 1 .In the example shown in FIG. 2, two outputs 7 are connected to the information broadcast line 8 of FIG.
Le dispositif de couplage de données 4 comprend par ailleurs une unité logique 1 d'aiguillage de l'information à diffuser vers la ou les sorties 7.The data coupling device 4 furthermore comprises a logical unit 1 for routing the information to be broadcast to the outlet (s) 7.
Le dispositif de couplage de données 4 peut comprendre également un module d'alimentation 16, des liaisons séries d'entrées/sorties classiques 25 (par exemple pour la gestion de dispositifs d'affichage sans interface de communication non filaire, la commande de périphérique telle qu'une radio musicale, l'interfaçage avec un GPS), et des entrées audio analogiques 18.The data coupling device 4 can also comprise a power supply module 16, conventional serial input / output connections 25 (for example for the management of devices display without a wired communication interface, device control such as a music radio, interfacing with a GPS), and analog audio inputs 18.
La présence de ces entrées audio analogiques auxiliaires 18 permet l'ajout de sources sonores et l'adaptation sur une installation ne possédant pas d'entrée audio suffisante, le dispositif de couplage de données 4 agissant alors comme un multiplexeur audio.The presence of these auxiliary analog audio inputs 18 makes it possible to add sound sources and adaptation to an installation that does not have sufficient audio input, the data coupling device 4 then acting as an audio multiplexer.
Ces entrées audio analogiques 18 sont amplifiées par un amplificateur 20, puis mixées dans un module de mixage audio 21 , en même temps que les sorties de l'unité logique 1 , après que ces dernières ont été éventuellement décompressées par le module de décompressionThese analog audio inputs 18 are amplified by an amplifier 20, then mixed in an audio mixing module 21, at the same time as the outputs of the logic unit 1, after the latter have possibly been decompressed by the decompression module.

Les données en sortie du module de mixage 21 sont envoyées sur la ou sur l'une des ligne(s) de sortie 7 pour diffusion par les moyens de diffusion d'information 3 de la figure 1 par l'intermédiaire de la ligne de diffusion d'information 8 de cette figure 1.The output data of the mixing module 21 are sent on the or on one of the output line (s) 7 for broadcasting by the information diffusion means 3 of FIG. 1 via the broadcast line 8 of this figure 1.
Eventuellement, ces données sont également renvoyées vers un amplificateur 22 pour amplification de la puissance.Optionally, these data are also sent to an amplifier 22 for power amplification.
Le dispositif de couplage de données 4 comprend également un module de contrôle de défaut 19.

This fault control module 19 makes it possible to permanently know the availability of the system, and to operate in "degraded" mode on a single audio channel in the case or the other is in default.
Ce module de contrôle de défaut 19 prend ses entrées notamment à partir du module amplificateur 20, du module de mixage audio 21 , et du module de décompression 23, et envoie en sortie ses instructions à l'unité logique 1 d'aiguillage de l'information à diffuser vers la ou les sorties 7.This fault control module 19 takes its inputs, in particular from the amplifier module 20, the audio mixing module 21, and the decompression module 23, and sends its instructions to the logic unit 1 for routing the signal. information to be broadcast to the outlet (s) 7.
Ainsi, le dispositif de couplage de données tel que représenté à la figure 2 comprend deux sorties 7 redondantes, vers la ligne de diffusion d'information 8 de la figure 1. En fonction du contrôle opéré par le module de contrôle de défaut 19, c'est l'une ou l'autre des sorties 7 qui sera utilisée.Thus, the data coupling device as represented in FIG. 2 comprises two redundant outputs 7, towards the information broadcast line 8 of FIG. 1. As a function of the control operated by the fault control module 19, FIG. is one of the 7 outputs that will be used.
Cette redondance permet donc d'assurer qu'en cas de canal défaillant sur une des sorties 7, l'autre prenne le relais pour assurer la diffusion d'information. Ceci est particulièrement important dans desThis redundancy makes it possible to ensure that in the event of a faulty channel on one of the outputs 7, the other takes over to ensure the dissemination of information. This is particularly important in
5 contextes où existent des contraintes réglementaires en ce qui concerne la diffusion d'information et la sécurité.5 contexts where there are regulatory constraints with respect to information dissemination and security.
Le dispositif de couplage de données 4 peut également comprendre une entrée micro d'ambiance 24, qui permet de mesurer le niveau de bruit ambiant et d'adapter le volume sonore général en fonction î o de ce bruit ambiant.The data coupling device 4 may also include a room microphone input 24, which makes it possible to measure the ambient noise level and to adapt the general sound volume as a function of this ambient noise.
Le dispositif de couplage de données 4 peut encore comprendre plusieurs entrées/sorties 27 destinées notamment à gérer la ligne audioThe data coupling device 4 may further comprise several inputs / outputs 27 intended in particular for managing the audio line
(par exemple commande de prise de ligne, détection d'occupation par une autre source), à commander et surveiller des périphériques (allumage d'un(eg line control, occupancy detection by another source), to control and monitor devices (ignition of a
15 voyant par exemple, ou encore fermeture d'une porte).15 seeing for example, or closing a door).
Le dispositif de couplage de données 4 peut également comprendre une ligne d'entrée odométrique 26, pour la mesure (programmable en fonction des capteurs utilisés) de la distance parcourue dans le but de connaître la position du véhicule.The data coupling device 4 may also comprise an odometric input line 26, for the measurement (programmable according to the sensors used) of the distance traveled in order to know the position of the vehicle.
20 Par ailleurs, une prise d'accès local 17 permet d'effectuer la maintenance sur le dispositif de couplage de données 4, en cas de défaut de la liaison non filaire par le module de communication 6.Furthermore, a local access socket 17 makes it possible to carry out maintenance on the data coupling device 4, in the event of the non-wired link being defective by the communication module 6.
Il est rappelé que l'ensemble de la description ci-dessus est donné à titre d'exemple et n'est donc pas limitatif de l'invention.It is recalled that the whole of the description above is given by way of example and is therefore not limiting of the invention.
25 En particulier, l'ensemble des éléments présentés ci-dessus a été décrit relativement à l'application au domaine du ferroviaire, le système étant embarqué dans un train contenant plusieurs voitures. Mais l'invention ne se limite pas à cette application. Le même système peut évidemment être embarqué également dans un bus, un avion, un taxi, ouIn particular, all of the elements presented above have been described with regard to the application to the railway field, the system being embedded in a train containing several cars. But the invention is not limited to this application. The same system can obviously also be embedded in a bus, a plane, a taxi, or
30 encore un navire.30 another ship.
De même, une grande partie de la description ci-dessus fait référence à la diffusion d'une information sonore (ou audio). La nature de l'information à diffuser n'est toutefois pas limitative de l'invention. A titre d'autre exemple, une information visuelle pourra tout aussi bien être diffusée, pourvu que des dispositifs d'affichage appropriés soient placés sur la ligne de diffusion d'information 8, comme les ou à la place des haut- parleurs 3, en tant que moyens de diffusion d'information 3.Likewise, much of the above description is reference to the broadcast of sound information (or audio). The nature of the information to be broadcast is however not limiting of the invention. As another example, visual information may equally well be broadcast, provided that appropriate display devices are placed on the information broadcast line 8, such as or instead of the loudspeakers 3, as means of dissemination of information 3.
Enfin, l'interface de communication 6 par voie non filaire du dispositif de couplage de données 4 étant modulaire, tout autre mode de transmission que le « Wifi » pourra être utilisé, tel que « Bluetooth » par exemple, en remplaçant ce module 6 par un autre module 6 approprié. Finally, since the non-wired communication interface 6 of the data coupling device 4 is modular, any other transmission mode than the "Wifi" can be used, such as "Bluetooth" for example, by replacing this module 6 with another appropriate module 6.
