Description

La présente invention se rapporte à un système de gestion de l'itinéraire d'un véhicule ferroviaire circulant sur un réseau ferroviaire entre un point de départ et un point d'arrivée.The present invention relates to a system for managing the route of a rail vehicle traveling on a railway network between a starting point and an arrival point.

Comme cela est classique, les réseaux ferroviaires comportent généralement des moyens de détection de la position du véhicule sur le réseau raccordés à une unité centrale de traitement dans laquelle est chargé un algorithme permettant de commander une modification de l'itinéraire du véhicule ferroviaire entre le point de départ et le point d'arrivée, et, en particulier, entre un noeud de changement d'itinéraire et un noeud de convergence avec un itinéraire initial.As is conventional, railway networks generally comprise means for detecting the position of the vehicle on the network connected to a central processing unit in which is loaded an algorithm making it possible to control a modification of the route of the railway vehicle between the point departure and arrival point, and in particular between a route change node and a convergence node with an initial route.

L'unité centrale permet, au moyen d'une interface machine appropriée, à un opérateur d'entrer successivement la liste des points du réseau selon lesquels le véhicule doit circuler en fonction d'événements externes susceptibles de nécessiter une modification du trajet initialement prévu.The central unit makes it possible, by means of an appropriate machine interface, for an operator to successively enter the list of points of the network according to which the vehicle must circulate as a function of external events that may necessitate a modification of the initially planned path.

Par exemple, une modification du trajet peut être rendue nécessaire par le fait qu'un quai de départ ou un quai d'arrivée est indisponible ou par la présence d'un obstacle sur la voie ferrée.For example, a change in the trip may be necessary due to the fact that a departure platform or an arrival platform is unavailable or the presence of an obstacle on the railway.

Pour modifier le trajet, l'opérateur saisit manuellement tous les points de passage entre le noeud de changement d'itinéraire et le noeud de convergence avec l'intermédiaire initial puis assure, s'il y a lieu, le lien avec les missions suivantes.To modify the path, the operator manually enters all the waypoints between the route change node and the convergence node with the initial intermediary and then, if necessary, provides the link with the following missions.

Cette technique bien que relativement efficace et sûre, présente un certain nombre d'inconvénients, notamment en raison du fait que cette opération est longue et doit, à ce jour, être effectuée manuellement.This technique, although relatively efficient and safe, has a number of disadvantages, in particular because this operation is long and must, to date, be performed manually.

Un des buts de l'invention est de pallier cet inconvénient.One of the aims of the invention is to overcome this drawback.

L'invention a donc pour objet un système de gestion de l'itinéraire d'un véhicule ferroviaire circulant sur un réseau ferroviaire entre un point de départ et un point d'arrivée, le réseau comportant des moyens de détection de la position du véhicule sur le réseau et une unité centrale de traitement comportant des moyens pour commander une modification de l'itinéraire du véhicule ferroviaire entre un noeud de changement d'itinéraire et un noeud de convergence avec un itinéraire initial, caractérisé en ce que les moyens pour commander une modification de l'itinéraire comportent des moyens pour déterminer l'ensemble des itinéraires possibles entre le noeud de changement d'itinéraire et le noeud de convergence et des moyens pour comparer ledit ensemble d'itinéraires avec l'itinéraire initial de manière à commander le changement d'itinéraire selon l'itinéraire le plus proche de l'itinéraire initialement prévu.The subject of the invention is therefore a system for managing the route of a rail vehicle traveling on a railway network between a starting point and an arrival point, the network comprising means for detecting the position of the vehicle on the network and a central processing unit comprising means for controlling a modification of the rail vehicle route between a route change node and a convergence node with an initial route, characterized in that the means for controlling a modification of the route comprise means for determining all the possible routes between the route change node and the convergence node and means for comparing said set of routes with the initial route so as to control the change of route. itinerary according to the route closest to the itinerary initially planned.

  • dans le cas où le véhicule ferroviaire est contraint de changer de quai de départ, le noeud de changement d'itinéraire est constitué par le point de départ du véhicule ferroviaire ; et
  • dans le cas où le véhicule ferroviaire est contraint de changer de quai d'arrivé, le noeud de convergence est un point virtuel situé en aval du point d'arrivé, le véhicule ferroviaire étant stoppé au niveau du quai d'arrivé se trouvant sur l'itinéraire modifié ;

  • in the case where the railway vehicle is forced to change the arrival platform, the convergence node is a virtual point located downstream of the arrival point, the railway vehicle being stopped at the arrival platform located on the modified itinerary;

D'autres caractéristiques et avantages ressortiront de la description suivante, donnée uniquement à titre d'exemple, et faite en référence aux dessins annexés sur lesquels :

  • la figure 1 est une vue schématique d'une portion de réseau ferroviaire équipée d'un système de gestion conforme à l'invention ;
  • la figure 2 est un organigramme montrant les différentes phases de fonctionnement du système de gestion de la figure 1 ;
  • la figure 3 est une vue schématique illustrant le cas d'un changement de quai de départ ;
  • la figure 4 est vue schématique illustrant le cas d'un changement de quai d'arrivé.
Other features and advantages will become apparent from the following description, given solely by way of example, and with reference to the appended drawings, in which:
  • the figure 1 is a schematic view of a railway network portion equipped with a management system according to the invention;
  • the figure 2 is a flowchart showing the different phases of operation of the management system of the figure 1 ;
  • the figure 3 is a schematic view illustrating the case of a change of departure platform;
  • the figure 4 is a schematic view illustrating the case of a change of arrival platform.

Sur la figure 1, on a représenté de façon schématique une portion de réseau ferroviaire doté d'un système de gestion d'itinéraire capable de calculer, en temps réel, l'itinéraire selon lequel un train circule entre un point de départ et un point d'arrivée.On the figure 1 schematically shows a portion of railway network with a route management system capable of calculating, in real time, the route in which a train runs between a starting point and an arrival point.

La portion 10 de réseau ferroviaire représenté sur cette figure 1 s'étend entre des points de départ 12,14, constitués chacun d'un ensemble de quais de départ, tels que 16 et 18, et des points d'arrivée 20 et 22, constitués également de quais d'arrivée, tels que 24 et 26.The portion 10 of the railway network represented on this figure 1 extends between starting points 12,14, each consisting of a set of departure platforms, such as 16 and 18, and arrival points 20 and 22, also consisting of arrival platforms, such as 24 and 26.

Dans l'exemple de réalisation représentée sur cette figure, la portion 10 de réseau comporte deux voies ferrées 28 et 30. Comme cela est classique, ces voies ferrées sont subdivisées en cantons et sont munies d'un dispositif d'aiguillage, tel que 32, assurant un aiguillage du véhicule ferroviaire entre les voies ferrées 28 et 30.In the exemplary embodiment shown in this figure, the network portion 10 comprises two railway tracks 28 and 30. As is conventional, these railways are subdivided into blocks and are provided with a switching device, such as 32 , providing a referral of the railway vehicle between the tracks 28 and 30.

Par ailleurs, le réseau ferroviaire est doté de dispositifs de détection de passage, tels que 34, régulièrement répartis dans chaque canton, de manière à procéder à une détection, en temps réel, de la position du véhicule ferroviaire sur la voie ferrée le long de laquelle il circule.Furthermore, the rail network is provided with passage detection devices, such as 34, regularly distributed in each block, so as to perform a real-time detection of the position of the railway vehicle on the railway along the line. which it circulates.

L'ensemble des équipements du réseau ferroviaire 10, à savoir les dispositifs d'aiguillage 32 et les dispositifs de détection 34 sont raccordés à une interface 36 d'acquisition de données et de commande des dispositifs d'aiguillage assurant l'acquisition des données issues des dispositifs de détection 34 et la commande des dispositifs d'aiguillage 32 en fonction d'un itinéraire initial prédéterminé, stocké en mémoire, entre un point de départ, tel que 12, et un point d'arrivée, tel que 20.All the equipment of the rail network 10, namely the switching devices 32 and the detection devices 34 are connected to an interface 36 for data acquisition and control of the switching devices ensuring the acquisition of data from detecting devices 34 and controlling the switching devices 32 according to a predetermined initial route, stored in memory, between a starting point, such as 12, and an end point, such as 20.

Conformément à l'invention, l'unité 36 est raccordée à une unité centrale de traitement 38 assurant le contrôle du fonctionnement de l'interface 36. En particulier l'unité centrale de traitement 38 gère l'interface avec l'unité de commande 36 par l'envoi de commandes intermédiaires et par l'acquisition de données issues des dispositifs d'aiguillage 32 et des dispositifs de détection 34, de manière à suivre la formation d'un itinéraire modifié, puis sa destruction progressive, au passage d'un train. Toute modification d'un itinéraire donne lieu à l'envoi par l'unité centrale de traitement 38 vers l'interface 36 de nouveaux ordres de commande des dispositifs d'aiguillage 32.According to the invention, the unit 36 is connected to a central processing unit 38 ensuring the control of the operation of the interface 36. In particular the central processing unit 38 manages the interface with the control unit 36 by sending intermediate commands and by acquiring data from the switching devices 32 and the detection devices 34, so as to follow the formation of a modified route, then its gradual destruction, at the passage of a train. Any modification of a route gives rise to the sending by the central processing unit 38 to the interface 36 of new control commands of the switching devices 32.

L'unité centrale 38 est constituée par un ordinateur central dans lequel sont chargés tous les programmes nécessaires pour provoquer les modifications d'itinéraires.The central unit 38 is constituted by a central computer in which are loaded all the programs necessary to cause the modifications of routes.

Elle est raccordée à une interface homme/machine 40 permettant à un opérateur d'entrer des ordres de modifications d'itinéraires et dispose d'une base de données (non représentée) dans laquelle sont chargés l'ensemble des itinéraires possibles entre les points de départ 12,14 et les points d'arrivée 20,22 du réseau ferroviaire 10.It is connected to a man / machine interface 40 allowing an operator to enter route change orders and has a database (not shown) in which all the possible routes between the points of interest are loaded. departure 12,14 and arrival points 20,22 of the rail network 10.

Plus particulièrement, l'unité centrale de traitement 38 comporte des moyens logiciels permettant d'extraire, de la base de données, l'ensemble des itinéraires possibles entre un noeud de changement d'itinéraire et un noeud de convergence avec l'itinéraire initial et des moyens logiciels pour comparer l'ensemble d'itinéraires extraits de la base de données avec l'itinéraire initial de manière à ne conserver que l'itinéraire le plus proche de l'itinéraire initialement prévu en vue de provoquer une modification de l'itinéraire selon l'itinéraire le plus proche ainsi déterminé. L'itinéraire le plus proche est choisi comme étant l'itinéraire modifié ayant le plus de point de passage du véhicule ferroviaire commun avec l'itinéraire initialement prévu.More particularly, the central processing unit 38 comprises software means making it possible to extract from the database all the possible routes between a route change node and a convergence node with the initial route and software means for comparing the set of routes extracted from the database with the initial route so as to keep only the route closest to the initially planned route in order to cause a modification of the route according to the closest route thus determined. The nearest route is chosen as the modified route having the most crossing point of the common rail vehicle with the initially planned route.

Par ailleurs, l'unité centrale de traitement 38 incorpore des moyens logiciels de calcul de la durée du trajet selon l'itinéraire ainsi modifié de manière à, par extrapolation, déterminer l'instant auquel le véhicule ferroviaire atteindra le point d'arrivée et des moyens pour modifier, à partir de cette information, la durée de séjour du véhicule ferroviaire au point d'arrivée de manière à éviter un décalage du service ferroviaire.In addition, the central processing unit 38 incorporates software means for calculating the journey time according to the route thus modified so as to extrapolate the time at which the railway vehicle will reach the arrival point and means for modifying, based on this information, the length of stay of the railway vehicle at the point of arrival so as to avoid a shift in the railway service.

Selon une caractéristique de l'invention, les moyens de calcul de la durée du trajet procèdent à un calcul de la durée de l'itinéraire canton par canton de manière à prévoir, pour chacun de ceux-ci, l'instant de passage du véhicule ferroviaire.According to a characteristic of the invention, the means for calculating the duration of the journey proceed to a calculation of the duration of the route canton by canton so as to provide, for each of these, the moment of passage of the vehicle. rail.

Une modification de l'itinéraire peut intervenir en un point quelconque du trajet ou de manière plus courante au niveau d'un point de départ ou d'un point d'arrivée, ces deux derniers changements correspondant respectivement à un changement de quai de départ et/ou d'arrivée. De plus, une modification du point d'arrivée peut avoir lieu alors que le véhicule ferroviaire parcourt déjà son itinéraire.A modification of the route may take place at any point along the route or more commonly at a starting point or an arrival point, the latter two changes respectively corresponding to a change of departure point and / or arrival. In addition, a modification of the arrival point may take place while the railway vehicle is already traveling on its route.

Dans la suite de la description, on considérera que le noeud de changement d'itinéraire est constitué par le point de départ 12 lui-même, le noeud de convergence avec l'itinéraire initial, désigné par la référence numérique générale 42 sur la figure étant dès lors constitué par un point du réseau ferroviaire situé en aval du point de départ 12.In the remainder of the description, it will be considered that the route change node is constituted by the starting point 12 itself, the convergence node with the initial route, designated by the general reference numeral 42 in the figure being therefore constituted by a point of the railway network situated downstream of the starting point 12.

En référence auxfigures 2 et 3, on va maintenant décrire les principales phases de fonctionnement du système de gestion d'itinéraire qui vient d'être décrit.Referring to FIGS. 2 and 3, the main phases of operation of the route management system just described will now be described.

Au cours d'une première phase 44, qui correspond à une phase lors de laquelle un opérateur décide que l'itinéraire initialement prévu doit être modifié, le trajet initialement prévu, représenté en pointillé sur la figure 3, est récupéré.During a first phase 44, which corresponds to a phase during which an operator decides that the initially planned route is to be modified, the initially planned route, represented in dotted line on the figure 3 , is recovered.

Lors de l'étape 46 suivante, l'opérateur entre, au moyen de l'interface homme/machine 40, une information relative au nouveau quai de départ 16.In the following step 46, the operator enters, via the man / machine interface 40, information relating to the new departure platform 16.

Lors de la phase 48 suivante, cette information est récupérée par l'unité centrale de traitement 38. Cette dernière procède à une comparaison entre l'itinéraire modifié et l'itinéraire initialement prévu et extrait, de la base de données, l'ensemble des itinéraires possibles entre le quai de départ 16 et le noeud de convergence 42 avec l'itinéraire initial.In the following phase 48, this information is retrieved by the central processing unit 38. The latter makes a comparison between the modified route and the route initially planned and extracted, from the database, all possible routes between the departure platform 16 and the convergence node 42 with the initial route.

Lors de l'étape 50 suivante, l'unité centrale de traitement 38 procède à une comparaison de l'ensemble des itinéraires ainsi obtenus avec l'itinéraire initial et ne conserve que l'itinéraire le plus proche de l'itinéraire initialement prévu. L'itinéraire le plus proche est choisi comme étant l'itinéraire modifié ayant le plus de points de passage du véhicule ferroviaire communs avec l'itinéraire initialement prévu.In the next step 50, the central processing unit 38 compares all the routes thus obtained with the initial route and retains only the route closest to the initially planned route. The nearest route is chosen as the modified route with the most common rail vehicle crossing points with the originally planned route.

Elle procède alors à une programmation de l'unité de commande 36 de manière à ce que cette dernière commande les équipements ferroviaires de manière à faire circuler le véhicule ferroviaire selon l'itinéraire ainsi programmé (étape 52).It then proceeds to a programming of the control unit 36 so that the latter controls the railway equipment so as to circulate the railway vehicle according to the route thus programmed (step 52).

L'unité centrale de traitement procède ainsi, par extrapolation, à la détermination de la trajectoire du véhicule et pilote l'unité de commande 36 de telle sorte que les dispositifs d'aiguillage soient actionnés à des instants propices pour que le véhicule ferroviaire soit aiguillé selon l'itinéraire programmé.The central processing unit thus proceeds, by extrapolation, to the determination of the trajectory of the vehicle and controls the control unit 36 so that the switching devices are actuated at favorable times for the rail vehicle to be switched according to the programmed route.

Lors de cette étape 52, l'unité centrale de traitement 38 procède, canton par canton, à un calcul de la durée de trajet en vue du pilotage des équipements ferroviaires.In this step 52, the central processing unit 38 proceeds, canton by canton, to a calculation of the journey time for the control of the railway equipment.

Enfin, au cours de cette étape, et à partir des informations de durée calculées, l'unité centrale 28 procède à une modification du temps de séjour du véhicule ferroviaire au point d'arrivée, en fonction du retard pris dû au changement d'itinéraire, de manière à ne pas décaler le service ferroviaire.Finally, during this step, and from the calculated duration information, the central unit 28 proceeds to a modification of the residence time of the railway vehicle at the arrival point, according to the delay taken due to the change of route , so as not to shift the rail service.

On vient de décrire le cas où le véhicule ferroviaire était contraint à un changement de quai de départ. On conçoit cependant, conformément à la figure 4, que lorsque l'itinéraire doit être modifié en raison de l'indisponibilité d'un quai d'arrivé, le point d'arrivé du véhicule ferroviaire est alors constitué par le quai d'arrivé 24 se trouvant sur l'itinéraire modifié, le noeud de changement d'itinéraire étant alors constitué par un point 43 du réseau ferroviaire situé en amont du point d'arrivé, en considérant le sens de circulation du véhicule ferroviaire le long de la voie ferrée. Dans un tel cas, l'itinéraire modifié parcouru par le véhicule ferroviaire ne comporte pas de noeud de convergence avec l'itinéraire initial, le noeud de convergence étant un point virtuel disposé en aval du point d'arrivé.We have just described the case where the railway vehicle was forced to change the starting platform. It is conceivable, however, in accordance with figure 4 , that when the route is to be changed due to the unavailability of an arrival platform, the arrival point of the railway vehicle is then constituted by the arrival platform 24 located on the modified route, the route change node then being constituted by a point 43 of the railway network located upstream of the arrival point, considering the direction of circulation of the railway vehicle along the railway. In such a case, the modified route traveled by the rail vehicle does not include a convergence node with the initial route, the convergence node being a virtual point disposed downstream of the arrival point.

Le système décrit ici est particulièrement utile, puisqu'il est adapté à une modification de l'itinéraire d'un véhicule ferroviaire alors même que le véhicule parcourt déjà cet itinéraire. Cette facilité permet de gérer facilement et rapidement les aléas imprévus pouvant survenir sur le réseau, notamment en cas d'indisponibilité du quai initialement prévu pour la réception d'un train.The system described here is particularly useful, since it is adapted to a modification of the route of a railway vehicle even though the vehicle is already traveling this route. This facility makes it possible to easily and quickly manage unforeseen hazards that may occur on the network, particularly in the event of unavailability of the wharf initially planned for receiving a train.
