Abstract

A central controller (38) has a unit which calculates the time duration along a route modified by the system controlling modified route itineraries. The controllers time computing unit calculates the time duration for each block section of the modify route itinerary. The controller can modify the waiting time of the railway vehicle at the arrival point and can modify an itinerary from the arrival point at the same moment the vehicle is traveling the arrival point track. The network includes vehicle position sensors (34) and a CPU (38). The itinerary modification controller includes means to determine a group of possible itineraries between the itinerary change node and the convergence node, and means for comparing the group of itineraries with the initial itinerary according to the closest itinerary to the initial one. In the case where the vehicle has to change its departure platform, the change itinerary node becomes the departure point (12,14) of the vehicle. In the case where the vehicle has its arrival platform changed, the convergence node is a virtual point situated downstream of the point of arrival. The vehicle being stopped at the arrival platform contained in the modified itinerary.

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 route management system for a railway vehicle traveling on a rail network between a starting point and a point arrival.

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, rail networks generally include means for detecting the position of the vehicle on the network connected to a unit central processing unit loaded with an algorithm for controlling a change in the route of the rail vehicle between the starting point and the point of arrival, and in particular between a route change node and a convergence 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 allows, by means of a suitable machine interface, a operator to successively enter the list of network points according to which the vehicle must circulate according to external events likely to require a modification of the originally planned route.

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 modification of the route may be necessary by the fact that a departure platform or an arrival platform is unavailable or by the presence of an obstacle on the railroad tracks.

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 route, the operator manually enters all of the passage between the route change node and the convergence node with the initial intermediary then ensures, if necessary, 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 effective and safe, presents a certain number of drawbacks, in particular due to the fact that 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 railway vehicle traveling on a rail network between a starting point and a point of arrival, 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 route of the rail vehicle between a change node route and a convergence node with an initial route, characterized in that the means for ordering a modification of the route include means for determine the set of 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 according to the route on closer to the route originally 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 rail vehicle is forced to change arrival platform, the convergence node is a virtual point located downstream from the arrival point, the rail 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 ;

Other characteristics and advantages will emerge from the following description, given solely by way of example, and made with reference to the appended drawings in which:
  • Figure 1 is a schematic view of a portion of the rail network equipped with a management system according to the invention;
  • Figure 2 is a flowchart showing the different operating phases of the management system of Figure 1;
  • Figure 3 is a schematic view illustrating the case of a change of departure platform;
  • Figure 4 is 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.In FIG. 1, a portion of the network is represented schematically railway equipped with a route management system capable of calculating, in real time, the route on which a train travels between a departure 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 rail network portion 10 shown in this figure 1 extends between starting points 12,14, each consisting of a set of starting docks, such as 16 and 18, and arrival points 20 and 22, also consisting of arrival docks, 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 embodiment shown in this figure, the portion 10 of network comprises two railways 28 and 30. As is conventional, these railways are subdivided into cantons and are provided with a switching device, such as 32, ensuring a railway vehicle switch 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.In addition, the rail network is equipped with detection devices passage, such as 34, regularly distributed in each canton, so as to proceed real-time detection of the position of the railway vehicle on the railway on along 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 devices switch 32 and the detection devices 34 are connected to an interface 36 data acquisition and control of referral devices ensuring acquisition data from the detection devices 34 and the control of the devices switch 32 according to a predetermined initial route, stored in memory, between a starting point, such as 12, and an ending 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. processing 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 of intermediate orders and by the acquisition of data from the devices switch 32 and detection devices 34, so as to follow the formation of a modified route, then its progressive destruction, when a train passes. all modification of a route gives rise to sending by the central processing unit 38 to the interface 36 for new control orders for 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 necessary programs to cause route modifications.

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 a operator to enter route modification orders and has a database of data (not shown) in which all the possible routes are loaded between the start points 12,14 and the finish 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 means software to extract all possible routes from the database between a route change node and a route convergence node initial and software means to compare the set of routes extracted from the database data with the original route so as to keep only the route closest to the route initially planned in order to cause a modification of the route according to the closest route thus determined. The closest route is chosen as being the modified route with the most common rail vehicle crossing point with the route originally planned.

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. Furthermore, the central processing unit 38 incorporates software means for calculation of the journey time according to the route thus modified so as to, by extrapolation, determine when the rail vehicle will reach the point of arrival and means of modifying, from this information, the duration of stay of the vehicle at the point of arrival in order to avoid a shift in rail 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 calculate the duration of the route canton by canton so as to provide, for each of these, the time of passage of the railway vehicle.

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 itinerary can take place at any point of the journey or more commonly at a starting point or an arrival point, these last two changes respectively corresponding to a platform change of departure and / or arrival. In addition, a modification of the end point can take place then that the rail vehicle is already 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 following description, we will consider that the change node of route consists of the starting point 12 itself, the convergence node with the initial route, designated by the general reference numeral 42 in the figure being from when constituted by a point on the rail network located downstream from 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.With reference to Figures 2 and 3, we will now describe the main operating phases of the route management system which has just been 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 should be changed, the route initially planned, shown in dotted lines in FIG. 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 next step 46, the operator enters, by means of the interface man / machine 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.During the next phase 48, this information is recovered by the unit central processing unit 38. The latter performs a comparison between the route modified 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 original 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.During the next step 50, the central processing unit 38 performs a comparison of all the routes thus obtained with the initial route and does not keeps only the route closest to the initially planned route. The itinerary on closest is chosen as the modified route with the most waypoints of the common rail vehicle with the route initially planned.

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 program the control unit 36 of so that the latter controls the railway equipment so as to make travel the rail 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 determining the trajectory of the vehicle and driving the control unit 36 so that that the switching devices are actuated at suitable times so that the rail vehicle is routed 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.During this step 52, the central processing unit 38 proceeds, block by canton, to calculate the journey time for piloting 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 modifies the residence time of the rail vehicle at the arrival point, depending on the delay due to the change of itinerary, so that do not 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 rail vehicle was forced to a change of departure platform. However, it can be seen, according to FIG. 4, that when the itinerary must be modified due to the unavailability of an arrival platform, the arrival point of the rail 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 rail network located upstream from the point of arrival, considering the direction of rail vehicle traffic along the railway track. In such a case, the route modified traveled by the railway vehicle does not include a convergence node with the initial route, the convergence node being a virtual point arranged downstream of the point of arrival.

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 suitable for a modification of the route of a rail vehicle even while the vehicle is traveling already this route. This facility allows you to easily and quickly manage hazards unforeseen events that may occur on the network, in particular in the event of the quay being unavailable initially planned for the reception of a train.
