DISPOSITIF ET PROCEDE DE TRANSMISSION D'INFORMATIONS PAR DEVICE AND METHOD FOR TRANSMITTING INFORMATION BY
BALISES ET BALISE UTILISEE DANS UN TEL DISPOSITIF BEACONS AND BEACON USED IN SUCH A DEVICE
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 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
balise utilisée dans un tel dispositif. beacon used in such a device.
Les dispositifs de transmission d'informations de Information transmission devices of
l'art antérieur font appel à des balises ponctuelles. the prior art uses point tags.
Ces balises sont des balises passives et sont These tags are passive tags and are
disposées au sol.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 FIG. 1 represents a device for transmitting information of the state of the art comprising equipment on board a railway vehicle and a
installation au sol.floor 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 The information transmission device shown in FIG. 1 comprises ground installations 1, 2 and on-board equipment 3, 4 in a vehicle
ferroviaire 5.rail 5.
Les installations au sol se composent d'une balise 1 et de son dispositif de commande 2, l'ensemble étant relié Ground installations consist of a beacon 1 and its control device 2, the assembly being connected
au moyens d'une ligne de transmission 7. by means of a transmission line 7.
La balise 1 est fixée sur des traverses, dans l'axe The beacon 1 is fixed on crosspieces, in the axis
d'une voie ferroviaire 6.a railway track 6.
Les équipements embarqués se composent principalement The on-board equipment mainly consists
d'une antenne 3 et d'une unité d'évaluation 4. 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 The evaluation unit 4, which can be a computer, is powered by its own converter and is connected to
l'antenne 3.antenna 3.
L'antenne 3 est située sous le véhicule ferroviaire 5, The antenna 3 is located under the rail vehicle 5,
de préférence à l'avant de celui-ci. 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 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
en aval de leur position géographique. downstream of their geographic position.
La réception de ces informations s'effectue & l'aide This information is received using
d'une antenne située sous le train. 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. Ces balises ont une longueur fixe, ce qui définit une région de l'espace dans laquelle l'antenne embarquée à bord 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. These beacons have a fixed length, which defines a region of space in which the antenna on board
d'un train est capable de recevoir le message émis. of a train is capable of receiving the transmitted message.
Cette longueur de captation, encore appelée longueur de contact, permet de transmettre un certain nombre de bits This capture length, also called contact length, makes it possible to transmit a certain number of bits
d'un message à transmettre.of a message to transmit.
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 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 the
lecture de la balise.reading the tag.
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 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 lu.message read.
La figure 2A montre une suite de messages Mn identiques émis par un dispositif de commande et transmis FIG. 2A shows a sequence of identical Mn messages sent by a control device and transmitted
via une balise à une antenne embarquée. via a beacon to an on-board antenna.
L'antenne embarquée dispose d'une fenêtre de lecture The on-board antenna has a reading window
prédéterminée qui est fonction de sa structure. predetermined which is a function of 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 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 parts
complémentaires de deux messages Mn successifs. complementary to two successive Mn messages.
La figure 2B illustre ce message binaire lu par Figure 2B illustrates this binary message read by
l'antenne embarquée.the on-board antenna.
La figure 2C illustre le message binaire reconstitué à FIG. 2C illustrates the binary message reconstructed at
bord du train.board the train.
A haute vitesse, la longueur de captation de l'antenne At high speed, the antenna capture length
ne permet donc pas la réception de plus d'un message. therefore does not allow the reception of more than one message.
3 27240753 2724075
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. Il apparait 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 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. It therefore appears a difficulty when the equipment responsible for establishing the messages sent switches the content of these messages, for example to take into account a change
d'état de la signalisation.signaling status.
Une conséquence de cette commutation du contenu des messages émis est que les messages émis avant et après cette A consequence of this switching of the content of the messages sent is that the messages sent before and after this
commutation ont un contenu différent. switching have different content.
Le message reconstitué à bord du train est alors incohérent car composé de deux parties d'un premier et d'un The message reconstructed on board the train is therefore incoherent because it consists of two parts, a first and a
second messages émis aux contenus différents. second messages sent with different content.
Aussi un but de l'invention est-il un dispositif de transmission d'informations par balises ne présentant pas Also an object of the invention is a device for transmitting information by tags not having
cet inconvénient.this disadvantage.

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 In addition, the beacon 1 is remotely powered only when a train 5 is present below the beacon 1. The remote power supply is carried out in a known manner by coupling
entre l'antenne 3 du train et la balise 1. 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 The beacon 1 is therefore not capable of supplying energy to supply a power line 7 of

La tension alternative correspondant aux messages émis n'étant pas courtcircuitée par la balise 1, les messages pourront être émis par le dispositif de commande 2 vers 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
l'antenne 3 embarquée au moyen de la balise 1. 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 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 the

It follows from the above a method of transmitting information Mn by means of a beacon 1
commandée par un dispositif de commande 2. 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 The information transmission method Mn comprises a first step consisting in 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 transmitted and a
