Description
La présente invention concerne un procédé destiné à permettre la mesure de la vitesse d'un véhicule circulant sur une voie de type ferroviaire.The present invention relates to a method intended for measuring the speed of a vehicle running on a railway type track.
La présente invention se rapporte également à l'installation destinée à la mise en oeuvre de ce procédé.The present invention also relates to the installation intended for the implementation of this process.
Différents systèmes de détermination de la vitesse d'un train circulant sur une voie ont déjà été proposés. En particulier, on a suggéré l'utilisation d'un capteur présent sur un essieu qui permet la détermination de la vitesse du train circulant sur la voie. Néanmoins, cette vitesse n'est pas toujours suffisamment précise, et en particulier, elle pourrait ne pas tenir compte d'un risque qui se produit lorsque la roue patine pour des raisons telles que les conditions climatiques (gel, neige) ou la présence de feuilles sur les rails.Different systems for determining the speed of a train running on a track have already been proposed. In particular, it has been suggested that a sensor on an axle that allows determination the speed of the train traveling on the track. However, this speed is not always sufficiently precise, and in particular, it may ignore a risk which occurs when the wheel slips for reasons such as weather conditions (frost, snow) or the presence of leaves on the rails.
On a également proposé de placer deux ou trois capteurs sur des essieux différents afin d'obtenir une meilleure précision. Ceci reste néanmoins insuffisant du point de vue de la gestion du risque. It has also been proposed to place two or three sensors on different axles to get better accuracy. This is still insufficient from a risk management perspective.
Il est également connu de disposer des balises le long des voies de chemin de fer afin d'effectuer une mesure de la vitesse du véhicule circulant sur ces voies. Dans ce cas, des balises qui sont disposées à des distances connues et fixes émettent un signal. Le véhicule passant près de cette balise détecte à l'aide d'une antenne le passage au-dessus de la première balise et effectue une mesure de temps jusqu'au passage de la seconde balise. On déduit aisément la vitesse à partir de la distance connue entre les deux balises et du temps mis par le véhicule pour parcourir cette distance. Néanmoins, les balises sont placées à des distances relativement importantes, et il s'agit essentiellement de mesurer des vitesses moyennes sur la distance parcourue.It is also known to have beacons along railroad tracks in order to perform a measurement of the speed of the vehicle traveling on these tracks. In this case, beacons which are arranged at known and fixed distances emit a signal. The vehicle passing near this tag detects using an antenna the passage above the first tag and performs a time measurement until the passage of the second beacon. We easily deduce the speed from the known distance between the two tags and the time taken by the vehicle to travel this distance. However, the tags are placed at relatively large distances, and it essentially to measure average speeds over the distance travelled.
Il a également été proposé par le document WO97/12796 d'utiliser une balise calibrée pour déterminer la vitesse quasi instantanée d'un véhicule passant dans son voisinage. Cette balise émet un champ magnétique, et par une antenne placée sous le véhicule, ce véhicule peut détecter l'entrée et la sortie de ce champ d'influence magnétique. On en déduit le temps que le véhicule met à traverser le champ d'influence magnétique et on calcule ainsi la vitesse du véhicule. Ce procédé présente l'inconvénient de devoir disposer de manière régulière des balises le long des voies.It was also proposed by the document WO97 / 12796 to use a calibrated tag to determine the almost instantaneous speed of a vehicle passing through its neighborhood. This beacon emits a magnetic field, and by an antenna placed under the vehicle, this vehicle can detect the entry and exit of this field of influence magnetic. We deduce the time that the vehicle takes to cross the magnetic influence field and we calculate thus the vehicle speed. This process presents the disadvantage of having to have regular access to beacons along the tracks.
D'autre part, il est connu d'organiser une voie en sections de voie appelées "cantonnements" séparées par des joints électriques. Un joint électrique est constitué de deux blocs d'accord servant au couplage énergétique des sections de voie adjacentes à chaque bloc d'accord et de la courte distance de voie située entre ces deux blocs d'accord (15 à 30 mètres). Habituellement, le premier bloc d'accord sert d'émetteur à une fréquence donnée tandis que le second bloc d'accord sert de récepteur à une autre fréquence. Les fonctions du joint électrique sont d'une part d'empêcher la propagation du signal d'un circuit de voie vers le circuit de voie adjacent et d'autre part de réaliser le couplage de l'émetteur et du récepteur avec la voie.On the other hand, it is known to organize a track in separate track sections called "cantonments" by electrical seals. An electrical joint is consisting of two chord blocks used for coupling energy of the sections of track adjacent to each block okay and the short track distance between these two chord blocks (15 to 30 meters). Usually the first chord block serves as a transmitter at a frequency given while the second chord block serves as a receiver at another frequency. The functions of the electrical seal are on the one hand to prevent the propagation of the signal of a track circuit to the adjacent track circuit and other part of coupling the transmitter and the receiver with the way.
Il est déjà connu d'utiliser un joint électrique pour détecter le passage d'un train. En effet, au passage des essieux du train, un court-circuit entre les deux rails est créé via les essieux du train et permet ainsi de détecter la position dudit train par rapport à l'émetteur d'après l'évolution du courant dans la voie. On observe en effet que le courant à la fréquence F1 dans un rail devant l'essieu est élevé avant le passage de l'essieu au droit de la connexion de l'émetteur et subit une forte discontinuité au moment du passage de l'essieu.It is already known to use a seal electric to detect the passage of a train. Indeed, when the axles of the train pass, a short circuit between the two rails is created via the axles of the train and allows thus detecting the position of said train relative to the transmitter according to the evolution of the current in the track. We indeed observes that the current at frequency F1 in a rail in front of the axle is raised before the axle passes to the right of the transmitter connection and undergoes a strong discontinuity when passing the axle.
La présente invention vise à fournir une solution qui puisse offrir le maximum de garanties de sécurité au sens ferroviaire du terme dans la mesure d'une vitesse d'un véhicule se déplaçant sur une voie de type ferroviaire.The present invention aims to provide a solution that can offer the maximum guarantees of safety in the railway sense of the term to the extent of speed of a vehicle moving on a type track rail.
La présente invention vise plus particulièrement à proposer un procédé qui permet une estimation de la vitesse moyenne de manière indépendante des causes d'erreurs dues par exemple au patinage et à l'embrayage des essieux, et qui est basé sur la détection au passage d'un train de joints séparant les différents circuits de voie.The present invention aims more particularly to propose a process which allows a estimate of average speed independently causes of errors due for example to skating and the axle clutch, and which is based on the detection the passage of a train of joints separating the different track circuits.
La présente invention vise à proposer un système qui peut s'affranchir du placement de balises le long des voies.The present invention aims to provide a system that can get rid of tag placement on along the tracks.
Plus particulièrement, la présente invention vise à utiliser des équipements déjà présents qui permettent la localisation du train et qui sont constitués par des circuits de voie à joints électriques.More particularly, the present invention aims to use already present equipment which allow the location of the train and which are made up by track circuits with electrical seals.
La présente invention se rapporte à un procédé de mesure de la vitesse d'un véhicule muni d'une antenne et circulant sur une voie à deux rails se présentant sous la forme de sections de voie appelées "cantonnements" séparées par des joints électriques, chaque joint électrique étant constitué de deux blocs d'accord et de la section de voie prédéterminée située entre eux, chacun des blocs d'accord permettant le couplage en énergie pour la section de voie adjacente servant de cantonnement, caractérisé en ce que l'on détecte au moins deux discontinuités en courant ou en tension du signal vu par une antenne présente dans le véhicule circulant sur la voie aux abords des régions des premier et second blocs d'accord d'un même joint électrique, en vue de mesurer la vitesse du véhicule circulant sur la voie.The present invention relates to a method of measuring the speed of a vehicle equipped with a antenna and traveling on a track with two rails in the form of sections of track called "cantonments" separated by electrical seals, each electrical joint consisting of two tuning blocks and the predetermined section of track located between them, each of the tuning blocks allowing energy coupling for the adjacent section of track serving as a block, characterized in that at least two are detected current or voltage discontinuities of the signal seen by an antenna present in the vehicle traveling on the track near the regions of the first and second chord blocks of the same electrical joint, in order to measure the speed of the vehicle traveling on the track.
La première discontinuité est obtenue lors du passage de l'essieu au droit du premier bloc d'accord pour la fréquence de ce premier bloc d'accord.The first discontinuity is obtained during passage of the axle to the right of the first block of agreement for the frequency of this first chord block.
La seconde discontinuité est obtenue en exerçant une action électrique à la fréquence du premier bloc d'accord. Cette seconde discontinuité est obtenue en créant un champ électrique ou magnétique dans la région du second bloc d'accord. Ce champ électrique ou magnétique est engendré au moyen d'un courant proportionnel au courant émis par la tension injectée au premier bloc d'accord. Ce champ est engendré directement par le courant émis par ladite tension.The second discontinuity is obtained in exerting an electrical action at the frequency of the first chord block. This second discontinuity is obtained by creating an electric or magnetic field in the region of second chord block. This electric or magnetic field is generated by a current proportional to the current emitted by the voltage injected at the first chord block. This field is generated directly by the current emitted by said voltage.
Selon une autre forme d'exécution, l'action électrique est une tension injectée en série avec la tension à la deuxième fréquence du deuxième bloc d'accord. Cette tension injectée en série est proportionnelle à celle qui est injectée au premier bloc d'accord.According to another embodiment, the action electric is a voltage injected in series with the voltage at the second frequency of the second chord block. This voltage injected in series is proportional to that which is injected into the first chord block.
Selon une autre forme d'exécution, l'action électrique est l'injection d'un courant dans un générateur de tension présent dans le second bloc d'accord, ce courant parcourant une boucle disposée entre les rails, ledit courant étant proportionnel au courant émis par la tension injectée au premier bloc d'accord.According to another embodiment, the action electric is the injection of a current into a generator of voltage present in the second chord block, this current traversing a loop arranged between the rails, said current being proportional to the current emitted by the voltage injected into the first chord block.
Le signal détecté par l'antenne qui se trouve à bord du véhicule circulant sur la voie est filtré à la fréquence de la tension injectée au premier bloc d'accord.The signal detected by the antenna located on board the vehicle traveling on the track is filtered at the frequency of the voltage injected at the first tuning block.
La présente invention se rapporte également à une installation pour la mise en oeuvre du procédé tel que décrit précédemment, dans laquelle la voie est organisée sous forme de cantonnements séparés par des joints électriques, chaque joint électrique étant constitué d'au moins deux blocs d'accord et de la courte section de voie située entre eux. Cette installation comprend des moyens pour générer au moins deux discontinuités en courant ou en tension dans le signal vu par l'antenne présente dans le véhicule circulant sur la voie aux abords des régions des premier et second blocs d'accord d'un même joint électrique.The present invention also relates to an installation for implementing the process such as previously described, in which the path is organized in the form of cantonments separated by joints electrical, each electrical joint consisting of at least minus two chord blocks and the short track section located between them. This installation includes means to generate at least two discontinuities in current or in voltage in the signal seen by the antenna present in the vehicle traveling on the track near the regions of first and second chord blocks of the same joint electric.

Un joint électrique tel que représenté à la figure 1 se compose d'un premier bloc d'accord TU.F1 situé d'un premier côté (à gauche), qui servira d'émetteur en vue de générer une tension dans la voie à la fréquence F1 et permet le couplage en énergie de ce premier côté (à gauche) de la voie adjacente au bloc d'accord. Un second bloc d'accord TU.F3, disposé à une distance de 15 à 30 mètres, permet le couplage en énergie de l'autre partie de la voie (à droite) adjacente à ce bloc d'accord. Ce second bloc d'accord sert de récepteur pour une fréquence F3. Il pourrait éventuellement également s'agir d'un émetteur qui permettrait de générer une tension à la fréquence F3.An electrical seal as shown in Figure 1 consists of a first TU.F1 chord block located a first side (left), which will serve as a transmitter in view to generate a voltage in the channel at the frequency F1 and allows the energy coupling of this first side (left) of the lane adjacent to the chord block. A second block agree TU.F3, placed at a distance of 15 to 30 meters, allows the energy coupling of the other part of the track (right) adjacent to this chord block. This second block agree serves as a receiver for a frequency F3. he could possibly also be a transmitter which would generate a voltage at frequency F3.
La figure 2 représente un circuit de voie comprenant plusieurs sections de voie organisées en cantonnements et séparées par des joints électriques constitués chacun de deux blocs d'accord couplés deux à deux. Pour une fréquence F1, les deux blocs d'accord TU.F1 et TU.F1' sont équivalents à une capacité qui réalise l'accord de la section de voie (cantonnement 1) comprise entre ces deux blocs, alors que les deux blocs d'accord TU.F3 et TU.F3' sont équivalents à des courts-circuits à cette même fréquence (F1). A la fréquence (F3) des circuits de voie adjacents, la fonction des blocs d'accord est alors inversée.Figure 2 shows a track circuit comprising several sections of track organized in cantonments and separated by electrical seals each consisting of two chord blocks coupled two to of them. For a frequency F1, the two tuning blocks TU.F1 and TU.F1 'are equivalent to a capacity which achieves track section agreement (block 1) included between these two blocks, while the two chord blocks TU.F3 and TU.F3 'are equivalent to short circuits to this same frequency (F1). At the frequency (F3) of the circuits adjacent channels, the function of the chord blocks is then reversed.
Comme représenté aux figures 3 et 4, le
passage de l'essieu 3 crée un shunt ou court-circuit entre
les rails 1 et 2. Plus précisément, le comportement du
courant I généré à la fréquence F1 et présent dans le rail
1 devant l'essieu 3 est modifié.As shown in Figures 3 and 4, the
passing
Comme représenté à la figure 5, on observe
que le courant I à la fréquence F1 reste élevé jusqu'au
moment où l'essieu approche de l'émetteur TU.F1 qui génère
le signal à la fréquence F1. Au droit dudit émetteur, on
observe que le courant I à la fréquence F1 chute
brusquement en créant une première discontinuité 7 à cet
endroit. La figure 5 représente en détails le comportement
du courant I devant l'essieu, en tenant compte de la
position de l'émetteur TU.F1 à l'abscisse -18 m alors que
TU.F3 sert de référence (0).As shown in Figure 5, we observe
that the current I at the frequency F1 remains high until
when the axle approaches the TU.F1 transmitter which generates
the signal at frequency F1. To the right of the said issuer,
observe that the current I at the frequency F1 drops
suddenly by creating a
La présente invention consiste à créer une deuxième discontinuité 8U aux abords du second bloc d'accord TU.F3 et à utiliser ces deux discontinuités survenant à une distance connue afin de pouvoir calculer la vitesse moyenne du train entre les deux positions où se produisent lesdites discontinuités.The present invention consists in creating a second 8U discontinuity near the second block agree TU.F3 and use these two discontinuities occurring at a known distance in order to be able to calculate the average train speed between the two positions where produce said discontinuities.
A cette fin, on prévoit de détecter à bord du
train un signal résultant du champ magnétique généré par le
courant I. Plus précisément, la tension V obtenue en
filtrant de manière connue les signaux d'antenne sera
proportionnelle au courant I présent dans les rails en
amont de l'essieu 3. Ce signal est capté à l'aide d'au
moins une antenne de type connu disposée en amont du
premier essieu 3. Le signal est filtré à la fréquence F1 en
vue de permettre la détection des deux discontinuités 7 et
8 du courant I. Un ou plusieurs autres signaux à la
fréquence F3 ou à d'autres fréquences peuvent être
également utilisés pour la détection d'autres paires de
discontinuités apparaissant sur d'autres circuits de voie.To this end, it is planned to detect on board the
train a signal resulting from the magnetic field generated by the
current I. More precisely, the voltage V obtained in
filtering in known manner the antenna signals will
proportional to the current I present in the rails in
upstream of
Selon une première forme d'exécution de la
présente invention, qui est plus particulièrement
représentée à la figure 6, on suggère de disposer une
boucle 4 entre les rails 1 et 2 à proximité du bloc TU.F3
constituant récepteur et équivalent à un court-circuit à la
fréquence F3. Cette boucle 4 est alimentée par un courant à
la fréquence F1 qui est de préférence proportionnel au
courant du bloc TU.F1. Elle est de préférence raccordée en
série avec ce bloc. De manière avantageuse, le champ
magnétique engendré par la boucle 4 crée la seconde
discontinuité 8 nécessaire à la mise en oeuvre du procédé
selon la présente invention.According to a first embodiment of the
present invention, which is more particularly
shown in Figure 6, we suggest having a

l'invention, qui est plus particulièrement représentée à la
figure 7, on propose de connecter un générateur de tension
5 à la fréquence F1 en série avec le bloc TU.F3. Dans ce
cas, le bloc TU.F3 est équivalent à un court-circuit pour
la fréquence F1. Le générateur 5 est de préférence alimenté
à partir de l'alimentation du bloc TU.F1.According to another preferred embodiment of
the invention, which is more particularly represented in the
Figure 7, we propose to connect a
La seconde discontinuité 8 sera obtenue lors
du passage au droit du bloc TU.F3 (abscisse = 0), la
tension étant proportionnelle à celle du bloc TU.F1
(émetteur à la fréquence F1).The
Selon une autre variante d'exécution,
représentée à la figure 8, un générateur de courant 6 est
branché en parallèle aux bornes du bloc TU.F3. Le courant
ainsi généré parcourt la boucle 9 disposée entre les deux
rails 1 et 2, créant ainsi un champ magnétique détectable à
cet endroit. Le générateur 6 à la fréquence F1 est
avantageusement disposé en série avec le bloc TU.F1 et crée
ainsi la seconde discontinuité recherchée 8. According to another variant,
shown in Figure 8, a
On a représenté à la figure 9 le courant I en
fonction de la distance parcourue sur les rails en
positionnant le bloc TU.F1 créant la première discontinuité
à -18 m et le bloc TU.F3 créant la seconde discontinuité au
point 0. On pourra détecter un signal à bord par filtrage
des signaux d'antenne à la fréquence F1 et détecter la
présence des deux discontinuités 7 et 8 dont les flancs
descendants sont liés à la position précise des blocs TU.F1
et TU.F3.FIG. 9 shows the current I in
depending on the distance traveled on the rails in
positioning the block TU.F1 creating the first discontinuity
at -18 m and the TU.F3 block creating the second discontinuity at
De manière classique, la détection de ces deux discontinuités détectées sera traitée à l'aide d'un microprocesseur, qui permet de définir l'intervalle de temps entre la détection desdites discontinuités. De manière classique, la connaissance de la distance précise entre les blocs TU.F1 et TU.F3 permettra de calculer la vitesse moyenne du véhicule circulant sur ladite voie entre les deux blocs TU.F1 et TU.F3.Conventionally, the detection of these two detected discontinuities will be treated using a microprocessor, which allows to define the interval of time between the detection of said discontinuities. Of classic way, knowing the precise distance between blocks TU.F1 and TU.F3 will calculate the average speed of the vehicle traveling on said track between the two blocks TU.F1 and TU.F3.
De manière particulièrement avantageuse, on observe que le coût d'installation du dispositif supplémentaire est relativement réduit et permet ainsi d'obtenir une mesure relativement précise de la vitesse du train circulant sur une voie. En outre, la mesure de cette vitesse reste indépendante d'un positionnement précis de balises, par exemple, dont le déplacement pourrait intervenir en cas d'interventions d'entretien de la voie, de phénomènes climatiques, de l'enrayage des roues, etc.Particularly advantageously, we notes that the cost of installing the device additional is relatively reduced and thus allows obtain a relatively precise measurement of the speed of the train running on a track. Furthermore, the measurement of this speed remains independent of a precise positioning of tags, for example, whose displacement could intervene in the event of track maintenance interventions, climatic phenomena, wheel engagement, etc.
