Description

L'invention se rapporte à un dispositif et à un procédé pour la localisation d'un véhicule ferroviaire le long d'une voie ferrée équipée d'un système de balises et plus particulièrement à un dispositif permettant la localisation précise et ponctuelle d'un véhicule ferroviaire par rapport à une balise émettant un signal électromagnétique pour la transmission d'informations. L'invention se rapporte également à une antenne destinée à équiper un véhicule ferroviaire dans un tel dispositif.The invention relates to a device and a method for locating a railway vehicle along a railway track equipped with a beacon system and more particularly to a device allowing precise and punctual localization of a rail vehicle in relation to a beacon emitting an electromagnetic signal for the transmission of information. The invention also relates to a antenna intended to equip a railway vehicle in such a device.

Il est connu d'équiper les réseaux de transport ferroviaire d'un système de balises permettant la transmission d'informations entre les balises disposées au sol et un équipement embarqué à bord du véhicule. Ainsi, le document FR-A-2 713 754 divulgue un système de balises au sol, alimentées par rayonnement, permettant la communication avec une antenne embarquée à bord d'un véhicule ferroviaire. En plus de la transmission d'informations, il est connu d'utiliser un tel système de balises pour localiser ponctuellement le véhicule ferroviaire sur la voie par la connaissance de l'emplacement de la balise qui est franchie par l'antenne embarquée sur le véhicule ferroviaire. Une telle localisation s'effectue habituellement par l'analyse de la puissance du signal capté par l'antenne, en faisant correspondre l'instant où le signal capté par l'antenne est maximal avec l'instant où l'antenne se trouve au-dessus de la balise.It is known to equip rail transport networks with a beacon system allowing the transmission of information between the beacons arranged on the ground and a equipment on board the vehicle. Document FR-A-2 713 754 discloses a system of beacons on the ground, powered by radiation, allowing the communication with an antenna on board a railway vehicle. In in addition to the transmission of information, it is known to use such a system of beacons to pinpoint the railway vehicle on the track from time to time knowledge of the location of the beacon which is crossed by the on-board antenna on the rail vehicle. Such localization is usually done by analyzing the strength of the signal received by the antenna, matching the instant when the signal received by the antenna is maximum with the instant when the antenna is found above the tag.

Toutefois, un tel procédé de localisation ne permet qu'une localisation imprécise du véhicule, le signal capté par l'antenne étant maximal sur une plage relativement grande pour permettre la transmission des informations. Ainsi, pour le système EUROBALISE utilisant des balises d'environ 50 cm de long, on obtient une précision sur la localisation du véhicule de l'ordre de ± 20 cm pour une vitesse du véhicule inférieure à 40 km/h et de l'ordre de ± 1 m pour une vitesse du véhicule supérieure à 300 km/h. However, such a localization method allows only an imprecise localization of the vehicle, the signal received by the antenna being maximum over a relatively wide range large to allow transmission of information. So for the system EUROBALISE using beacons about 50 cm long, we obtain a accuracy on the location of the vehicle of the order of ± 20 cm for a speed of vehicle less than 40 km / h and around ± 1 m for vehicle speed greater than 300 km / h.

Une telle précision est insuffisante pour les systèmes de contrôle automatique de véhicule, notamment pour un métro, pour lequel une précision généralement inférieure à ± 5 cm est nécessaire pour assurer, dans les stations, un bon positionnement du métro relativement au quai.Such precision is insufficient for automatic control systems. vehicle, especially for a metro, for which precision generally less than ± 5 cm is necessary to ensure, at stations, good metro positioning relative to the platform.

Le but de la présente invention est donc de proposer un dispositif et un procédé de localisation d'un véhicule ferroviaire qui permette de localiser ponctuellement et précisément le véhicule ferroviaire par rapport à un système de balises, notamment de type EUROBALISE, et qui soit simple et économique à réaliser.The object of the present invention is therefore to propose a device and a method for localization of a railway vehicle which makes it possible to localize punctually and precisely the rail vehicle compared to a beacon system, in particular EUROBALISE type, which is simple and economical to produce.

Pour faciliter la lecture du dessin, seuls les éléments nécessaires à la compréhension de l'invention ont été représentés.To make the drawing easier to read, only the elements necessary for understanding of the invention have been shown.

La figure 1 représente un dispositif de localisation ponctuelle d'un véhicule ferroviaire sur une voie ferrée comportant des installations au sol qui se composent principalement de balises 2, de type connu en soi, munies de leur électronique de commande et fixées le long de la voie ferrée en des emplacements connus.Figure 1 shows a point-in-time location device for a vehicle railway on a railway track with ground facilities that consist mainly beacons 2, of a type known per se, provided with their electronic control and fixed along the track in known locations.

Le dispositif de localisation comporte également des équipements embarqués à bord du véhicule ferroviaire qui se composent principalement d'une antenne réceptrice et d'une unité d'évaluation 6. L'unité d'évaluation 6, qui peut être un calculateur, est alimentée par son propre convertisseur et est connectée à l'antenne 1. L'antenne 1 est située sous le véhicule à un emplacement tel que l'antenne 1 passe dans l'axe des balises 2 lorsque le train circule sur la voie ferrée.The location device also includes equipment on board of the railway vehicle which mainly consist of a receiving antenna and of an evaluation unit 6. The evaluation unit 6, which can be a calculator, is powered by its own converter and is connected to the antenna 1. The antenna 1 is located under the vehicle in a location such that the antenna 1 passes in the axis of the beacons 2 when the train is running on the track.

Conformément à la figure 2, les balises 2 comportent un circuit d'émission muni d'une boucle émettrice destinée à émettre des ondes électromagnétiques représentatives de l'information à transmettre au véhicule. De manière préférentielle, les balises 2 sont alimentées par rayonnement en provenance d'un émetteur embarqué par l'antenne 1 du véhicule ferroviaire, ce dernier fournissant l'énergie nécessaire au fonctionnement de la balise 2 qui est franchie par le véhicule ferroviaire. Cette alimentation électrique de la balise 2 est réalisée par exemple en intégrant dans la balise un circuit d'antenne muni d'une bobine réceptrice connecté en série au primaire d'un transformateur d'isolement, le secondaire de ce dernier étant connecté au circuit d'émission de la balise. Avantageusement, les balises 2 sont conformes à la norme européenne EUROBALISE, c'est à dire qu'elles assurent la communication par couplage magnétique avec l'antenne 1 du véhicule dans la bande de fréquence 3,9 - 4,5 MHz, ces balises présentant l'avantage d'être compactes, avec une longueur d'environ 50 cm et légères, avec un poids d'environ 5 kg.In accordance with FIG. 2, the beacons 2 comprise a transmission circuit provided a transmitting loop intended to emit electromagnetic waves representative of the information to be transmitted to the vehicle. Preferably, the beacons 2 are supplied with radiation from a transmitter on board the antenna 1 of the rail vehicle, the latter providing the energy necessary for the operation of the beacon 2 which is crossed by the vehicle rail. This electrical supply of the beacon 2 is produced for example by integrating into the beacon an antenna circuit provided with a connected take-up coil in series at the primary of an isolation transformer, the secondary of the latter being connected to the beacon transmission circuit. Advantageously, the tags 2 are in accordance with the European standard EUROBALISE, i.e. they ensure the communication by magnetic coupling with the antenna 1 of the vehicle in the band of frequency 3.9 - 4.5 MHz, these beacons having the advantage of being compact, with a length of about 50 cm and light, with a weight of about 5 kg.

L'antenne 1 du véhicule comporte, de manière connue en soi, un premier circuit récepteur 3 qui est constitué par une boucle simple. Le premier circuit récepteur 3 est destiné à capter le signal émis par la balise 2 et est connecté à l'unité d'évaluation 6 du véhicule qui assure l'analyse des informations transmises par la balise 2 franchie par l'antenne 1.The antenna 1 of the vehicle comprises, in a manner known per se, a first circuit receiver 3 which consists of a single loop. The first receiver circuit 3 is intended to receive the signal emitted by the beacon 2 and is connected to the evaluation unit 6 of the vehicle which analyzes the information transmitted by the tag 2 crossed by antenna 1.

Conformément à l'invention, l'antenne 1 comporte également un second circuit récepteur 4 qui est constitué par une boucle en forme de huit, cette dernière étant sensiblement concentrique avec la boucle simple du premier circuit récepteur 3. Le second circuit récepteur 4 est également connecté à l'unité d'évaluation 6 du véhicule. De manière préférentielle, la taille de la boucle en huit est voisine de la taille de la boucle d'émission de la balise 2 afin d'atteindre une précision optimale sur la localisation de l'antenne 1.According to the invention, the antenna 1 also includes a second circuit receiver 4 which consists of an eight-shaped loop, the latter being substantially concentric with the simple loop of the first receiving circuit 3. The second receiver circuit 4 is also connected to the evaluation unit 6 of the vehicle. Preferably, the size of the figure-eight loop is close to the size of the beacon 2 emission loop in order to achieve optimal precision on the location of the antenna 1.

Le fonctionnement du dispositif et du procédé de localisation ponctuelle du véhicule ferroviaire par rapport à une balise va maintenant être décrit.The operation of the device and the point-in-time method of locating the vehicle rail relative to a beacon will now be described.

Lorsque le véhicule approche d'une balise 2 et que l'émetteur de l'antenne 1 du véhicule se situe dans la zone de contact de la balise 2, c'est à dire que le niveau d'énergie capté par la balise au sol est suffisant pour assurer son fonctionnement, la balise 2 émet un signal électromagnétique représentatif de l'information à transmettre.When the vehicle approaches a beacon 2 and the transmitter of antenna 1 of the vehicle is in the contact zone of beacon 2, i.e. the level of energy captured by the beacon on the ground is sufficient to ensure its operation, the beacon 2 emits an electromagnetic signal representative of the information to pass.

Ce signal est capté par l'antenne 1 du véhicule et notamment par la boucle formant le premier circuit récepteur 3. La puissance du signal capté par le premier circuit récepteur 3, en fonction du déplacement de l'antenne 1 portée par le véhicule suivant l'axe X, est représentée sur la figure 3. Conformément à cette figure 3, le premier circuit récepteur 3 de l'antenne 1 délivre un signal S3 qui est maximum sur une plage relativement large qui est centrée sur la zone de contact de la balise 2, le signal ainsi capté pouvant favorablement être utilisé par l'unité d'évaluation 6 pour analyser les informations transmises par la balise 2. En début et en fin de la zone de contact balise, l'amplitude du signal varie pour s'annuler en début et en sortie de la zone de contact avec toutefois la présence de lobes secondaires, de part et d'autre de la zone de contact.This signal is picked up by the antenna 1 of the vehicle and in particular by the loop forming the first receiving circuit 3. The power of the signal picked up by the first receiving circuit 3, as a function of the movement of the antenna 1 carried by the vehicle according to l axis X, is represented in FIG. 3. In accordance with this FIG. 3, the first receiver circuit 3 of the antenna 1 delivers a signal S 3 which is maximum over a relatively wide range which is centered on the contact zone of the beacon 2, the signal thus captured can favorably be used by the evaluation unit 6 to analyze the information transmitted by the beacon 2. At the beginning and at the end of the beacon contact area, the amplitude of the signal varies for cancel at the start and exit of the contact zone with, however, the presence of secondary lobes on either side of the contact zone.

Dans le même temps, le signal émis par la balise 2 est capté par le second circuit récepteur 4 de l'antenne 1. La puissance du signal capté par le second circuit récepteur 4 en fonction du déplacement de l'antenne 1 suivant l'axe X est représentée sur la figure 4. Conformément à cette figure 4, le second circuit récepteur 4 délivre un signal S4 qui varie en amplitude au début et à la fin de la zone de contact de la balise 2 et qui est nul au centre de la zone de contact, c'est à dire lorsque le point de croisement de la boucle en huit est centré sur la boucle d'émission de la balise 2. Le signal S4 comporte également des lobes secondaires de part et d'autre de la zone de contact. De plus, conformément à la figure 5 qui représente la différence de phase entre le signal délivré par le second circuit récepteur 4 et le signal délivré capté par le premier circuit récepteur 3, il se produit un changement de phase de 180° entre le signal issu du premier circuit récepteur 3 et le signal issu du second circuit récepteur 4 lorsque le centre de la boucle en huit du second circuit récepteur 4 passe au droit du centre de la balise 2.At the same time, the signal emitted by the beacon 2 is picked up by the second receiver circuit 4 of the antenna 1. The power of the signal picked up by the second receiver circuit 4 as a function of the movement of the antenna 1 along the axis X is represented in FIG. 4. In accordance with this FIG. 4, the second receiving circuit 4 delivers a signal S 4 which varies in amplitude at the start and at the end of the contact zone of the beacon 2 and which is zero in the center of the contact zone, that is to say when the crossing point of the eight loop is centered on the emission loop of the beacon 2. The signal S 4 also includes secondary lobes on either side of the contact area. In addition, in accordance with FIG. 5 which represents the phase difference between the signal delivered by the second receiver circuit 4 and the delivered signal picked up by the first receiver circuit 3, there is a phase change of 180 ° between the signal from of the first receiver circuit 3 and the signal from the second receiver circuit 4 when the center of the figure-eight loop of the second receiver circuit 4 passes in line with the center of the beacon 2.

Le procédé de localisation ponctuelle selon l'invention consiste donc à détecter, à l'aide de l'unité d'évaluation 6, le changement de phase de 180° entre le signal délivré par le second circuit récepteur 4 et le signal délivré par le premier circuit récepteur 3, afin d'en déduire l'instant où l'antenne 1 est centré sur la balise 2. Un tel procédé de localisation permet d'identifier l'instant où l'antenne 1 est centré sur la balise 2 avec une précision inférieure à ± 5 cm et donc de localiser ponctuellement le véhicule sur la voie ferrée avec une précision du même ordre.The point localization method according to the invention therefore consists in detecting, at using the evaluation unit 6, the phase change of 180 ° between the signal delivered by the second receiving circuit 4 and the signal delivered by the first circuit receiver 3, in order to deduce the instant when the antenna 1 is centered on the beacon 2. Such a localization process makes it possible to identify the instant when the antenna 1 is centered on the beacon 2 with an accuracy of less than ± 5 cm and therefore localize the point vehicle on the track with a precision of the same order.

De manière avantageuse, et afin d'augmenter la sécurité du procédé de localisation, la localisation de l'antenne 1 par rapport à la balise 2 ne sera validée que si le signal émis par la balise 2 contient un message informationnel, l'unité d'évaluation 6 vérifiant ainsi que le changement de phase détecté est accompagné de la réception d'un message clair par le premier circuit récepteur 3 pour valider la localisation. De plus, la sécurité du procédé de localisation peut également être renforcée par la mise en place d'un seuil en tension afin de filtrer tous les changements de phase intempestifs qui peuvent apparaítre sur les lobes secondaires existants aux extrémités du contact balise.Advantageously, and in order to increase the security of the localization process, the location of antenna 1 relative to beacon 2 will only be validated if the signal emitted by the tag 2 contains an informational message, the evaluation unit 6 thus verifying that the detected phase change is accompanied by reception a clear message by the first receiver circuit 3 to validate the location. Of more, the security of the localization process can also be reinforced by the implementation in place of a voltage threshold in order to filter all phase changes untimely which can appear on the existing secondary lobes at the ends of the beacon contact.

Un tel dispositif associé à un tel procédé présente ainsi l'avantage de permettre un recalage ponctuel, au passage de chaque balise, du véhicule ferroviaire sur la voie ferrée avec une précision inférieure à ± 5 cm, et cela en conservant une balise standard de type EUROBALISE très répandu sur les réseaux ferrés.Such a device associated with such a method thus has the advantage of allowing a punctual readjustment, when each beacon passes, of the railway vehicle on the track rail with an accuracy of less than ± 5 cm, and this while keeping a beacon EUROBALISE type standard widely used on rail networks.

Il est ainsi possible en équipant un véhicule ferroviaire de l'antenne selon l'invention d'obtenir une précision sur le positionnement du véhicule suffisante pour l'exploitation des systèmes de contrôle automatique de train.It is thus possible by equipping a railway vehicle with the antenna according to the invention to obtain sufficient precision on the positioning of the vehicle to the operation of automatic train control systems.

Le dispositif et le procédé de localisation selon l'invention permettent donc, en équipant simplement les véhicules ferroviaires d'une antenne selon l'invention, d'obtenir de manière très économique une très bonne précision sur les points de recalage du véhicule sur la voie ferrée.The location device and method according to the invention therefore make it possible, in simply equipping railway vehicles with an antenna according to the invention, very economically to obtain very good precision on the points of registration of the vehicle on the railway.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is in no way limited to the embodiment described and illustrated which has been given only as an example. Modifications are still possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without however leaving the field of protection of the invention.
