Abstract

The information transmission system includes the beacon (1) which is controlled by the control device (2), the beacon being fitted beneath the rails of a railway line. The signal transmitted by the beacon is picked up by the aerial (3) mounted on board the railway vehicle (5), for transmission to a unit (4) within the vehicle. When a vehicle is in the region of the beacon, the switching between successive messages is delayed. The transmission (7) which supplies the beacon carries an alternating voltage corresponding to the message, and a direct current component.

Description

La présente invention concerne les systèmes automatiques, au sol et embarqués, de contrôle du trafic sur les réseaux de transports urbains, en générale, et porte, plus particulièrement, sur un dispositif et un procédé de transmission d'informations par balises ainsi que sur une balise utilisée dans un tel dispositif.The present invention relates to automatic systems, on the ground and on board, for traffic control on urban transport networks, in general, and relates, more particularly, to a device and a method for transmitting information by beacons as well as to a beacon used in such a device.

Les dispositifs de transmission d'informations de l'art antérieur font appel à des balises ponctuelles.The prior art information transmission devices use point beacons.

Ces balises sont des balises passives et sont disposées au sol.These beacons are passive beacons and are arranged on the ground.

La figure 1 représente un dispositif de transmission d'informations de l'état de la technique comprenant un équipement embarqué dans un véhicule ferroviaire et une installation au sol.FIG. 1 represents a device for transmitting information of the state of the art comprising equipment on board a rail vehicle and a ground installation.

Le dispositif de transmission d'informations représenté à la figure 1 comprend des installations au sol 1, 2 et des équipements embarqués 3, 4 dans un véhicule ferroviaire 5.The information transmission device shown in FIG. 1 comprises ground installations 1, 2 and on-board equipment 3, 4 in a rail vehicle 5.

Les installations au sol se composent d'une balise 1 et de son dispositif de commande 2, l'ensemble étant relié au moyens d'une ligne de transmission 7.Ground installations consist of a beacon 1 and its control device 2, the assembly being connected by means of a transmission line 7.

La balise 1 est fixée sur des traverses, dans l'axe d'une voie ferroviaire 6.The beacon 1 is fixed on sleepers, in the axis of a railway track 6.

Les équipements embarqués se composent principalement d'une antenne 3 et d'une unité d'évaluation 4.The on-board equipment mainly consists of an antenna 3 and an evaluation unit 4.

L'unité d'évaluation 4, qui peut être un ordinateur, est alimentée par son propre convertisseur et est connecté à l'antenne 3.The evaluation unit 4, which can be a computer, is powered by its own converter and is connected to the antenna 3.

L'antenne 3 est située sous le véhicule ferroviaire 5, de préférence à l'avant de celui-ci.The antenna 3 is located under the rail vehicle 5, preferably at the front of it.

Les balises utilisées dans les systèmes de contrôle, par exemple de la vitesse d'un train, permettent la transmission d'informations sur l'état de la signalisation en aval de leur position géographique.The beacons used in the control systems, for example of the speed of a train, allow the transmission of information on the state of the signaling downstream of their geographical position.

La réception de ces informations s'effectue à l'aide d'une antenne située sous le train.This information is received using an antenna located under the train.

La balise émet une série de bits en série, par exemple à un débit de 50 kbits/s, au moyen d'un équipement électronique de commande chargé d'élaborer un message.The beacon transmits a series of bits in series, for example at a speed of 50 kbits / s, by means of electronic control equipment responsible for preparing a message.

Ces balises ont une longueur fixe, ce qui définit une région de l'espace dans laquelle l'antenne embarquée à bord d'un train est capable de recevoir le message émis.These beacons have a fixed length, which defines a region of space in which the antenna on board a train is capable of receiving the message transmitted.

Cette longueur de captation, encore appelée longueur de contact, permet de transmettre un certain nombre de bits d'un message à transmettre.This capture length, also called contact length, makes it possible to transmit a certain number of bits of a message to be transmitted.

La lecture d'un message binaire s'effectue entre un dispositif de commande et le train via une balise. Une synchronisation s'effectue entre le début du message et l'arrivée du train sur la balise et donc au début de la lecture de la balise.A binary message is read between a control device and the train via a beacon. Synchronization takes place between the start of the message and the arrival of the train on the beacon and therefore at the start of reading the beacon.

Les figures 2A à 2C illustrent, respectivement, l'émission de messages Mn au moyen d'une balise de l'état de la technique, la lecture du message au moyen de l'antenne embarquée puis la reconstitution du message émis à partir du message lu.FIGS. 2A to 2C illustrate, respectively, the transmission of messages Mn by means of a beacon of the state of the art, the reading of the message by means of the on-board antenna then the reconstruction of the message transmitted from the message read.

La figure 2A montre une suite de messages Mn identiques émis par un dispositif de commande et transmis via une balise à une antenne embarquée.FIG. 2A shows a series of identical Mn messages sent by a control device and transmitted via a beacon to an on-board antenna.

L'antenne embarquée dispose d'une fenêtre de lecture prédéterminée qui est fonction de sa structure.The on-board antenna has a predetermined reading window which depends on its structure.

Le message binaire lu par l'antenne embarquée peut ne pas correspondre au message Mn complet, mais correspond le plus souvent à une juxtaposition de deux parties complémentaires de deux messages Mn successifs.The binary message read by the on-board antenna may not correspond to the complete Mn message, but most often corresponds to a juxtaposition of two complementary parts of two successive Mn messages.

La figure 2B illustre ce message binaire lu par l'antenne embarquée.FIG. 2B illustrates this binary message read by the on-board antenna.

La figure 2C illustre le message binaire reconstitué à bord du train.FIG. 2C illustrates the binary message reconstructed on board the train.

A haute vitesse, la longueur de captation de l'antenne ne permet donc pas la réception de plus d'un message.At high speed, the antenna reception length therefore does not allow the reception of more than one message.

Une conséquence de ce qui précède est qu'il est possible à partir de la lecture d'un seul message émis de reconstituer ce message émis à la seule condition que les deux parties de messages disponibles appartiennent à des messages émis successifs aux contenus identiques.One consequence of the above is that it is possible, from the reading of a single sent message, to reconstitute this sent message on the sole condition that the two parts of available messages belong to successive sent messages with identical contents.

Il apparaît donc une difficulté lorsque l'équipement chargé d'établir les messages émis commute le contenu de ces messages, par exemple pour prendre en compte un changement d'état de la signalisation.A difficulty therefore appears when the equipment responsible for establishing the messages sent switches the content of these messages, for example to take into account a change in signaling state.

Une conséquence de cette commutation du contenu des messages émis est que les messages émis avant et après cette commutation ont un contenu différent.One consequence of this switching of the content of the messages sent is that the messages sent before and after this switching have a different content.

Le message reconstitué à bord du train est alors incohérent car composé de deux parties d'un premier et d'un second messages émis aux contenus différents.The message reconstructed on board the train is therefore incoherent because it consists of two parts of a first and a second message sent with different contents.

Aussi un but de l'invention est-il un dispositif de transmission d'informations par balises ne présentant pas cet inconvénient.An object of the invention is therefore a device for transmitting information by beacons which does not have this drawback.

Un autre but de l'invention est un dispositif de transmission d'information par balises permettant à tout instant la reconstitution de messages cohérents.Another object of the invention is a device for transmitting information by beacons allowing the reconstitution of coherent messages at any time.

Conformément à l'invention, le dispositif de transmission d'informations Mn au moyen d'une balise commandée par un dispositif de commande, lesdites informations Mn étant transmises à une antenne au moyen de ladite balise, ladite antenne étant embarquée sur un véhicule, ledit dispositif de commande étant susceptible d'effectuer une commutation C entre lesdits messages Mn et des messages Mn+1, se caractérise en ce que, lors de la présence dudit véhicule à proximité de ladite balise, ledit dispositif de commande retarde ladite commutation C entre lesdits messages Mn et lesdits messages Mn+1 en émettant un ou plusieurs messages Mn supplémentaire Mns.According to the invention, the device for transmitting information Mn by means of a beacon controlled by a control device, said information Mn being transmitted to an antenna by means of said beacon, said antenna being carried on a vehicle, said control device being capable of effecting a switching C between said messages Mn and messages Mn + 1, is characterized in that, when said vehicle is near said beacon, said control device delays said switching C between said Mn messages and said Mn + 1 messages by transmitting one or more additional Mn Mns messages.

L'invention a pour objet un dispositif satisfaisant également à l'une des caractéristiques suivantes:

L'invention porte également sur une balise pour dispositif de transmission d'informations.The invention also relates to a tag for an information transmission device.

Conformément à l'invention, la balise pour dispositif de transmission d'informations est connectée à un dispositif de commande par une ligne de transmission, et se caractérise par des moyens de transmissions, audit dispositif de commande, d'un signal relatif à la présence d'un véhicule à proximité de ladite balise.According to the invention, the tag for information transmission device is connected to a control device by a transmission line, and is characterized by means of transmission, to said control device, of a signal relating to the presence of a vehicle near said tag.

L'invention a pour objet une balise pour dispositif de transmission d'informations comportant:

  • une première interface, sensible uniquement à des signaux alternatifs, dont la fonction est de recevoir lesdits messages émis par ledit dispositif de commande puis de les transmettre de manière à ce qu'une antenne embarquée sur un véhicule puisse lire ces messages Mn,

The subject of the invention is a tag for an information transmission device comprising:
  • a first interface, sensitive only to alternating signals, the function of which is to receive said messages transmitted by said control device and then to transmit them so that an antenna on board a vehicle can read these messages Mn,

L'invention porte également sur un procédé de transmission d'informations.The invention also relates to a method for transmitting information.

Conformément à l'invention, le procédé de transmission d'informations Mn au moyen d'une balise commandée par un dispositif de commande, se caractérise par les étapes suivantes:

  • retardement, au moyen dudit dispositif de commande, de ladite commutation C entre lesdits messages Mn et lesdits messages Mn+1, par la transmission, au moyen dudit dispositif de commande, d'un ou plusieurs messages Mn supplémentaires Mns.
According to the invention, the method of transmitting information Mn by means of a beacon controlled by a control device, is characterized by the following steps:

  • detection of the short circuit by said control device,
  • delay, by means of said control device, of said switching C between said messages Mn and said messages Mn + 1, by the transmission, by means of said control device, of one or more additional Mn messages Mns.

D'autres buts, caractéristiques et avantages de l'invention apparaîtront à la lecture de la description du mode de réalisation préféré du dispositif de transmission d'informations par balises, description faite en liaison avec les dessins dans lesquels:

Other objects, characteristics and advantages of the invention will appear on reading the description of the preferred embodiment of the device for transmitting information by beacons, description made in conjunction with the drawings in which:
  • FIG. 1 represents a device for transmitting state of the art information comprising equipment on board a railway vehicle and a ground installation,
  • FIGS. 2A to 2C illustrate, respectively, the transmission of messages Mn by means of a beacon of the state of the art, the reading of the message by means of the on-board antenna then the reconstruction of the message transmitted from the message read, according to a principle known from the state of the art,
  • FIGS. 3A to 3E illustrate, respectively, the transmission of messages Mn by means of a beacon of the state of the art, the appearance of information of the presence of a train, the delayed transmission of the switching between the messages Mn and the messages Mn + 1 by means of a beacon in accordance with the principle of the invention, the reading of the message by means of the on-board antenna then the reconstitution of the message transmitted from the message read,
  • FIG. 4 represents a block diagram of a preferred embodiment of a beacon used in the device for transmitting information by beacons according to the invention.

Les figures 1 et 2 sont décrites ci-dessus.Figures 1 and 2 are described above.

Les figures 3A à 3E illustrent l'émission retardée de la commutation C entre les messages Mn et les messages Mn+1 au moyen d'une balise conforme au principe de l'invention.FIGS. 3A to 3E illustrate the delayed transmission of the switching C between the messages Mn and the messages Mn + 1 by means of a beacon conforming to the principle of the invention.

Pour éviter que le message reconstitué ne soit incohérent, il est possible de tenir le dispositif de commande informé de la présence d'un train à l'aplomb de la balise.To prevent the reconstituted message from being inconsistent, it is possible to keep the control device informed of the presence of a train directly above the beacon.

Cette information relative à la présence d'un train permet de générer un retard dans la commutation C du contenu des messages.This information relating to the presence of a train makes it possible to generate a delay in the switching C of the content of the messages.

Lorsqu'un train arrive à l'aplomb d'une balise, celle-ci transmet au dispositif de commande une information relative à la présence du train qui permet au dispositif de commande de retarder la commutation C du contenu des messages émis.When a train arrives below a beacon, this transmits to the control device information relating to the presence of the train which allows the control device to delay the switching C of the content of the messages sent.

Pour ce faire, le dispositif de commande émet un ou plusieurs messages Mn supplémentaires Mns vers la balise de manière à retarder la commutation C entre les messages Mn et les messages Mn+1.To do this, the control device transmits one or more additional Mn messages Mns to the beacon so as to delay switching C between the Mn messages and the Mn + 1 messages.

Il résulte de ce qui précède que les deux demi-messages lus par l'antenne embarquée sont cohérents et permettrons donc la reconstitution d'un message également cohérent.It follows from the above that the two half-messages read by the on-board antenna are coherent and therefore allow the reconstitution of an equally coherent message.

La figure 4 représente un schéma synoptique d'un mode de réalisation préféré d'une balise utilisée dans le dispositif de transmission d'informations par balises conforme à l'invention.FIG. 4 represents a block diagram of a preferred embodiment of a beacon used in the device for transmitting information by beacons according to the invention.

La balise 1 utilisée dans le système de transmission d'informations est un équipement passif, c'est à dire n'ayant pas de source d'énergie électrique propre permanente.The tag 1 used in the information transmission system is passive equipment, that is to say having no permanent own electrical energy source.

De plus, la balise 1 est téléalimenté uniquement lorsqu'un train 5 est présent à l'aplomb de la balise 1. La télé alimentation est effectuée de façon connue par couplage entre l'antenne 3 du train et la balise 1.In addition, the beacon 1 is remotely supplied only when a train 5 is present below the beacon 1. The remote supply is carried out in a known manner by coupling between the antenna 3 of the train and the beacon 1.

La balise 1 n'est donc pas capable de fournir de l'énergie pour alimenter une ligne électrique 7 de transmission vers le dispositif de commande 2.The beacon 1 is therefore not capable of supplying energy to supply an electric line 7 for transmission to the control device 2.

L'information relative à la présence d'un train est élaboré, conformément à l'invention, par la superposition par le dispositif de commande 2 de deux signaux sur la ligne de transmission 7 vers la balise 1.The information relating to the presence of a train is produced, in accordance with the invention, by the superimposition by the control device 2 of two signals on the transmission line 7 towards the beacon 1.

Ces signaux superposés sont constitués d'une tension alternative correspondant aux messages émis Mn et d'une polarisation en courant continu de la ligne de transmission correspondant à l'information relative à la présence d'un train.These superimposed signals consist of an alternating voltage corresponding to the messages sent Mn and of a direct current polarization of the transmission line corresponding to the information relating to the presence of a train.

En présence d'un train 5, la balise 1 court-circuite l'extrémité de la ligne de transmission en provenance du dispositif de commande 2 pour le courant continu uniquement.In the presence of a train 5, the tag 1 short-circuits the end of the transmission line coming from the control device 2 for direct current only.

Le dispositif de commande 2 détecte alors un court-circuit sur la ligne de transmission 7 pour le courant continu uniquement et en déduit une information relative à la présence d'un train 5 à l'aplomb de la balise 1 connectée à la ligne court-circuitée.The control device 2 then detects a short circuit on the transmission line 7 for direct current only and deduces therefrom information relating to the presence of a train 5 directly above the beacon 1 connected to the short line. circuited.

La tension alternative correspondant aux messages émis n'étant pas court-circuitée par la balise 1, les messages pourront être émis par le dispositif de commande 2 vers l'antenne 3 embarquée au moyen de la balise 1.Since the alternating voltage corresponding to the messages sent is not short-circuited by the beacon 1, the messages can be sent by the control device 2 to the antenna 3 on board by means of the beacon 1.

La balise 1 est donc connectée à le dispositif de commande 2 par une ligne de transmission 7 et se compose:

  • d'une première interface 8 sensible uniquement aux signaux alternatifs et
  • d'une seconde interface 9 sensible uniquement au courant continu.
The beacon 1 is therefore connected to the control device 2 by a transmission line 7 and consists of:
  • a first interface 8 sensitive only to alternating signals and
  • a second interface 9 sensitive only to direct current.

La première interface 8 sensible uniquement aux signaux alternatifs a pour fonction la réception des messages émis par le dispositif de commande 2 et destinés à être lu par l'antenne embarquée 3.The first interface 8 sensitive only to AC signals has the function of receiving messages sent by the control device 2 and intended to be read by the on-board antenna 3.

La seconde interface 9 sensible uniquement au courant continu a pour fonction de court-circuiter la ligne de transmission 7 pour le courant continu uniquement.The second interface 9 sensitive only to direct current has the function of short-circuiting the transmission line 7 for direct current only.

Il résulte de ce qui précède un procédé de transmission d'informations Mn au moyen d'une balise 1 commandée par un dispositif de commande 2.It follows from the above a method of transmitting information Mn by means of a beacon 1 controlled by a control device 2.

Le procédé de transmission d'informations Mn comporte une première étape consistant à superposer, sur la ligne de transmission 7 reliant la balise 1 et le dispositif de transmission 2, au moyen du dispositif de commande 2, une tension alternative correspondant aux messages émis et un courant continu.The information transmission method Mn comprises a first step consisting of superimposing, on the transmission line 7 connecting the beacon 1 and the transmission device 2, by means of the control device 2, an alternating voltage corresponding to the messages sent and a direct current.

Une deuxième étape consiste à mettre en court-circuit pour le courant continu seulement, au moyen des moyens de transmissions 9, la ligne de transmission 7, lors de la réception, au moyen des moyens de transmissions 9, d'une information 10 relative à la présence du véhicule 5 à proximité de la balise 1.A second step consists in short-circuiting for direct current only, by means of the transmission means 9, the transmission line 7, when receiving, by means of the transmission means 9, information 10 relating to the presence of the vehicle 5 near the beacon 1.

L'étape suivante consiste à détecter le court-circuit au moyen du dispositif de commande 2.The next step is to detect the short circuit by means of the control device 2.

Une quatrième étape consiste à retarder, au moyen du dispositif de commande 2, la commutation C entre les messages Mn et les messages Mn+1, par la transmission, toujours au moyen du dispositif de commande 2, d'un ou plusieurs messages Mn supplémentaires Mns.A fourth step consists in delaying, by means of the control device 2, the switching C between the messages Mn and the messages Mn + 1, by the transmission, still by means of the control device 2, of one or more additional messages Mn Mns.
