Description
La présente invention concerne un dispositif d'élimination d'erreurs de comptage d'essieux pour véhicule ferroviaire. Elle se rapporte également à un boggie de véhicule ferroviaire pourvu d'un tel dispositif d'élimination d'erreurs.The present invention relates to an axle counting error elimination device for a railway vehicle. It also relates to a rail vehicle bogie provided with such an error elimination device.
L'invention concerne également un procédé de contrôle du passage d'un véhicule ferroviaire dans un canton d'un réseau ferroviaire comme décrit dans le document
Généralement, par souci de sécurité, on autorise l'entrée d'un véhicule ferroviaire dans un canton lorsque le véhicule qui le précède en est sorti.Generally, for safety reasons, the entry of a railway vehicle into a block is authorized when the vehicle preceding it has left.
Par exemple, le contrôle du passage d'un véhicule ferroviaire dans un canton et, en particulier, la détection de la sortie du véhicule du canton, s'effectue en incrémentant, en entrée du canton, un compteur/décompteur, à chaque passage d'un essieu du véhicule et en le décrémentant, en sortie du canton, à chaque passage d'un essieu.For example, the control of the passage of a railway vehicle in a block and, in particular, the detection of the exit of the vehicle of the canton, is carried out by incrementing, at the entry of the canton, a counter / downward counter, at each passage of an axle of the vehicle and decreasing it, at the exit of the canton, with each passage of an axle.
On considère que le véhicule sort du canton lorsque le résultat de la décrémentation est égal à zéro.The vehicle is considered to leave the block when the result of the decrement is zero.
Certains types de véhicules ferroviaires, et en particulier les véhicules de maintenance, sont pourvus, sur chaque boggie, d'un châssis palpeur ou d'auscultation situé au voisinage immédiat des rails et destiné à mesurer les principales caractéristiques des files de rails sur lesquelles ils circulent, tels que le rayon de courbure, l'écartement, le dévers, l'usure des rails,..., ou les caractéristiques internes des rails pour vérifier leur état.Certain types of railway vehicles, and in particular maintenance vehicles, are provided on each bogie with a feeler or inspection chassis located in the immediate vicinity of the rails and intended to measure the main characteristics of the rail lines on which they are installed. circulate, such as the radius of curvature, the spacing, the slope, the wear of the rails, ..., or the internal characteristics of the rails to check their state.
La présence de ces châssis est susceptible d'engendrer des erreurs de comptage d'essieux dans la mesure où, en fonction de la vitesse du véhicule, les châssis peuvent être considérés par des moyens de détection d'essieux associés au compteur/décompteur, comme une roue de véhicule ferroviaire ou, au contraire, à vitesse plus élevée, ne pas être pris en compte.The presence of these frames is likely to cause axle counting errors in that, depending on the speed of the vehicle, the chassis can be considered by means of axle detection associated with the up / down counter, as a rail vehicle wheel or, on the contrary, at a higher speed, not be taken into account.
Dès lors, la présence de ces châssis est susceptible d'être responsable de dysfonctionnements au sein des compteurs/décompteurs de détection des véhicules lorsque, comme cela est généralement le cas, la vitesse d'un véhicule en entrée du canton est différente celle du véhicule en sortie du canton, le résultat de la décrémentation, après sortie du véhicule du canton, pouvant être non nul.Therefore, the presence of these frames is likely to be responsible for malfunctions within the vehicle detection meters / decounters when, as is generally the case, the speed of a vehicle entry of the canton is different than the vehicle at the exit of the canton, the result of the decrementation, after exit of the canton vehicle, may be non-zero.
Lorsque de tels véhicules circulent sur des portions de voie ferrée pourvues de dispositifs de comptage d'essieux, les exploitants des réseaux ferroviaires doivent prévoir des moyens humains destinés à la remise à zéro manuelle des compteurs/décompteurs, après passage de ces véhicules.Where such vehicles are used on railway sections equipped with axle counting devices, the operators of the railway networks must provide for human resources intended for the manual resetting of the up / down counters, after passing these vehicles.
On conçoit dès lors que ce type de procédure engendre un surcoût non négligeable pour les exploitants des réseaux ferroviaires.It is therefore conceivable that this type of procedure generates a significant additional cost for the operators of the rail networks.
Le but de l'invention est donc de pallier cet inconvénient.The object of the invention is therefore to overcome this disadvantage.
Ainsi, selon l'invention, il est proposé un dispositif d'élimination d'erreurs de comptage d'essieux pour véhicule ferroviaire comprenant, selon un aspect de l'invention, un pont en matériau magnétique destiné à être monté longitudinalement entre deux roues consécutives d'un boggie du véhicule.Thus, according to the invention, there is provided an axle counting error elimination device for a railway vehicle comprising, according to one aspect of the invention, a magnetic material bridge intended to be mounted longitudinally between two consecutive wheels. a boggie of the vehicle.
Selon un mode de réalisation de ce dispositif, le pont magnétique comporte au moins une barre métallique destinée à être portée par le boggie.According to one embodiment of this device, the magnetic bridge comprises at least one metal bar intended to be carried by the bogie.
Par exemple, la ou chaque barre est montée sur au moins un barreau de fixation sur le boggie et s'étend généralement perpendiculairement audit barreau.For example, the or each bar is mounted on at least one fixing bar on the bogie and extends generally perpendicular to said bar.
De préférence, les zones d'extrémité libre mutuellement opposées de la ou chaque barre ont respectivement une forme complémentaire de celle de la roue et du châssis palpeur au voisinage desquels elles s'étendent.Preferably, the mutually opposite free end regions of the or each bar respectively have a shape complementary to that of the wheel and the feeler frame in the vicinity of which they extend.
Selon un exemple de réalisation, le pont en matériau magnétique comporte deux barres s'étendant chacune entre une roue du boggie et un palpeur de mesure de caractéristiques de la voie ferrée.According to an exemplary embodiment, the bridge of magnetic material comprises two bars each extending between a wheel of the bogie and a probe for measuring characteristics of the railway.
Selon l'invention, il est également proposé un boggie de véhicule ferroviaire équipé d'un dispositif d'élimination d'erreurs de comptage d'essieux tel que défini ci-dessus.According to the invention, it is also proposed a rail vehicle bogie equipped with an axle counting error elimination device as defined above.
L'invention propose également un procédé de contrôle du passage d'un véhicule ferroviaire dans un canton d'un réseau ferroviaire au cours duquel on incrémente un compteur à chaque détection d'un essieu du véhicule en entrée du canton, on décrémente le compteur à chaque détection d'un essieu en sortie du canton et l'on décide que le véhicule est sorti du canton lorsque le résultat de la décrémentation est nul.The invention also proposes a method of controlling the passage of a railway vehicle in a canton of a railway network during which a counter is incremented each time an axle of the vehicle is detected at the entrance of the block, the counter is decremented at each detection of an axle at the exit of the block and it is decided that the vehicle is out of the block when the result of the decrementation is zero.
Selon un aspect de ce procédé, le véhicule étant pourvu d'au moins un pont magnétique s'étendant longitudinalement entre deux roues consécutives du boggie du véhicule, au cours de l'étape d'incrémentation et de l'étape de décrémentation, on élimine les erreurs de comptage en ne détectant que les ensembles constitués de roues consécutives du véhicule et d'un pont magnétique correspondant.According to one aspect of this method, the vehicle being provided with at least one magnetic bridge extending longitudinally between two consecutive wheels of the vehicle bogie, during the step of incrementing and the decrementation step, eliminates the counting errors by detecting only sets consisting of consecutive wheels of the vehicle and a corresponding magnetic bridge.

figure 2 .
Sur la
La voie ferrée est subdivisée en un ensemble de cantons juxtaposés, tels que C. Comme on le voit sur cette figure, et de manière classique, chaque canton est pourvu, en entrée et en sortie, de moyens 14 de comptage d'essieux aptes à assurer, en entrée, un comptage du nombre d'essieux du véhicule ferroviaire entrant dans le canton C et, en sortie, à décompter le nombre d'essieux du véhicule sortant.The railway is subdivided into a set of juxtaposed blocks, such as C. As can be seen in this figure, and in a conventional manner, each block is provided, at the input and at the output, with
Ces moyens de comptage sont constitués par des éléments de type classiques, à la portée d'un homme du métier. Ils ne seront donc pas décrits en détail par la suite. On notera cependant qu'ils sont associés à des moyens de détection électronique d'essieux, également de type classique, aptes à détecter la présence du matériau magnétique constitutif des roues, et sont adaptés pour être incrémentés, en entrée du canton C, et être décrémentés, en sortie du canton, à chaque passage d'un essieu en regard des moyens de détection.These counting means are constituted by elements of conventional type, within the reach of a person skilled in the art. They will not be described in detail later. However, it will be noted that they are associated with electronic axle detection means, also of conventional type, capable of detecting the presence of the magnetic material constituting the wheels, and are adapted to be incremented, at the entrance of the canton C, and to be decremented at the output of the block, each passage of an axle facing the detection means.
Il est ainsi décidé que le véhicule sort du canton lorsque le résultat de la décrémentation est nul.It is thus decided that the vehicle leaves the canton when the result of the decrementation is zero.
Ces moyens de comptage et de décomptage pilotent des moyens de signalisation, tels que 16, de manière à interdire l'entrée d'un véhicule suiveur tant que le véhicule qui le précède n'est pas sorti du canton.These counting and counting means control signaling means, such as 16, so as to prohibit the entry of a follower vehicle as the vehicle that precedes it has not left the canton.
On a représenté sur les
On a en effet représenté sur la
On voit sur cette figure que le boggie, désigné par la référence numérique générale 18, lequel est destiné à être monté sur le châssis principal de la voiture, est pourvu de deux essieux 20 et 22 portant chacun une roue R.It is seen in this figure that the bogie, designated by the
Entre les roues, le boggie est pourvu d'un galet ou châssis palpeur ou d'auscultation 24 assurant, comme cela est classique, la détection et la mesure de caractéristiques de la voie ferrée sur laquelle il circule, telles que le rayon de courbure, l'écartement des rails, le dévers, ..., ou la détection de caractéristiques internes à la voie pour surveiller son état.Between the wheels, the bogie is provided with a roller or sensing
Dans le but d'éviter toute fausse détection lors du passage d'un essieu, par exemple due à la présence du châssis palpeur 24, détecté ou non en fonction de la vitesse du véhicule, le boggie 18 est pourvu de deux barres 26 et 28 s'étendant chacune entre le châssis palpeur 24 et l'une des roues R.In order to avoid any false detection during the passage of an axle, for example due to the presence of the
Sur la
On crée ainsi un pont magnétique, constitué par les deux barres et incorporant le châssis palpeur, s'étendant longitudinalement entre les deux roues R. En fonctionnement, les moyens de détection d'essieu ne détectent alors, à chaque passage, que l'ensemble du pont magnétique.A magnetic bridge is thus created, constituted by the two bars and incorporating the feeler frame, extending longitudinally between the two wheels R. In operation, the axle detection means then detect, at each passage, only the entire assembly. magnetic bridge.
Sur la
Les barres 26 et 28 sont réalisées en un matériau ferromagnétique, de préférence le même matériau que celui entrant dans la constitution des roues R. Afin d'améliorer la continuité magnétique entre les roues R, les extrémités libres mutuellement opposées des barres 26 et 28 sont conformées de manières à avoir une forme complémentaire de la roue et du châssis palpeur, respectivement, au voisinage desquels elles s'étendent.The
Ainsi, en particulier, comme visible sur la
En se référant à la
Comme indiqué précédemment, on crée selon l'invention un pont magnétique entre deux roues consécutives du boggie du véhicule, permettant d'éviter tout risque de dysfonctionnement lors du comptage et du décomptage des essieux.As indicated above, according to the invention, a magnetic bridge is created between two consecutive wheels of the vehicle's bogie, making it possible to avoid any risk of malfunction during the counting and down-counting of the axles.
En effet, et comme on le conçoit, les moyens de comptage et de décomptage d'essieux, et en particulier les moyens de détections qui leurs sont associés, ne considèrent chacun que l'ensemble constitué par les roues et le pont magnétique entre ces dernières, à savoir le châssis palpeur et les barres 26 et 28.Indeed, and as is conceivable, the means for counting and counting axles, and in particular the detecting means associated with them, each consider only the assembly constituted by the wheels and the magnetic bridge between the latter. , namely the feeler frame and the
On conçoit enfin que l'invention n'est pas limitée au mode de réalisation envisagé. Il est en effet également possible de réaliser le pont magnétique de tout autre forme ou agencement apte à réaliser une continuité magnétique entre les roues R.Finally, it is conceivable that the invention is not limited to the embodiment envisaged. It is indeed also possible to make the magnetic bridge of any other shape or arrangement capable of achieving a magnetic continuity between the wheels R.
Ainsi, par exemple, le pont magnétique peut être réalisé en n'utilisant qu'une barre s'étendant entre les roues R. De même, il est possible de conformer différemment les moyens de support des barres, en fonction de l'espace disponible.Thus, for example, the magnetic bridge can be made using only one bar extending between the wheels R. Similarly, it is possible to differently shape the support means of the bars, depending on the available space .
