Description
La présente invention concerne une installation de gestion de la circulation de véhicules sur un réseau ferroviaire, le réseau étant subdivisé en une pluralité de ressources voie présentant au moins deux extrémités, l'installation gérant la circulation au moins d'un premier véhicule et d'un deuxième véhicule, l'installation comportant une pluralité de contrôleurs au sol et une pluralité de tables de consignation, chaque ressource voie étant propre à un unique contrôleur au sol, chaque table étant propre à une ressource voie et étant propre à stocker des données relatives à la gestion des véhicules.The present invention relates to a vehicle traffic management installation on a railway network, the network being subdivided into a plurality of track resources having at least two ends, the installation managing the circulation of at least a first vehicle and of a second vehicle, the installation comprising a plurality of ground controllers and a plurality of log tables, each channel resource being specific to a single ground controller, each table being specific to a channel resource and being able to store data relating to to vehicle management.
La présente invention concerne également un procédé de gestion de la circulation de véhicules sur un réseau ferroviaire, pour la circulation de véhicules circulant au sein d'une telle installation.The present invention also relates to a method for managing the circulation of vehicles on a railway network, for the circulation of vehicles circulating within such an installation.
Dans le présent document, on entend par « véhicule », tout véhicule apte à se déplacer sur un réseau ferroviaire, comme par exemple un train, un tramway, un métro.In this document, the term "vehicle", any vehicle able to move on a rail network, such as a train, a tram, a subway.
Un réseau ferroviaire est composé de différents objets élémentaires, comme par exemple une section de voie à deux points d'extrémité, une section de voie à trois points d'extrémité ou aiguille, un élément de signalisation, etc.A rail network is composed of different elementary objects, such as for example a section of track with two end points, a section of track with three end points or a needle, a signaling element, etc.
A un instant donné, chaque objet se trouve dans un état d'enclenchement présentant une valeur particulière parmi une pluralité de valeurs possibles, prédéfinies. L'état d'enclenchement instantané d'un objet est la combinaison des valeurs de plusieurs paramètres permettant de caractériser complètement l'état de l'objet. Par exemple, l'état d'enclenchement instantané d'une aiguille est l'association de deux valeurs, la première valeur appartenant à l'ensemble « position 1 de l'aiguille / position 2 de l'aiguille », la seconde valeur appartenant à l'ensemble « aiguille enclenchée / aiguille non enclenchée ».At a given time, each object is in a latching state having a particular one of a plurality of predefined possible values. The state of instantaneous engagement of an object is the combination of the values of several parameters making it possible to completely characterize the state of the object. For example, the state of instantaneous engagement of a needle is the association of two values, the first value belonging to the set "

De manière générale, un central de régulation au sol planifie la circulation des différents trains circulant sur le réseau ferroviaire et affecte auxdits trains des missions correspondant à la route du réseau qu'ils doivent emprunter. Le réseau est subdivisé en plusieurs ressources. Une ressource est un objet élémentaire particulier et est caractérisée respectivement par un état d'allocation, prenant la valeur « allouée » ou « non-allouée », et par un état d'enclenchement, prenant une valeur parmi une pluralité de valeurs prédéterminées.In general, a ground control center plans the circulation of the various trains running on the rail network and assigns to these trains missions corresponding to the network route they must take. The network is subdivided into several resources. A resource is a particular elementary object and is respectively characterized by an allocation state, taking the value "allocated" or "unallocated", and by an interlocking state, taking one of a plurality of predetermined values.
Chaque contrôleur de bord de chaque train autorise le mouvement, en sécurité, du train correspondant, sur un chemin composé des ressources allouées au train et lui permettant de poursuivre la mission qui lui a été affectée. Pour ce faire, chaque contrôleur de bord est propre à réserver des ressources identifiées, en générant des requêtes d'allocation de ressource destinées à des contrôleurs au sol. Chaque contrôleur au sol est propre à une des ressources identifiées.Each train controller of each train allows the safe movement of the corresponding train on a path composed of the resources allocated to the train and allowing it to continue the mission assigned to it. To do this, each controller is able to reserve identified resources, generating resource allocation requests for ground controllers. Each ground controller is specific to one of the identified resources.
Si une telle installation de gestion de la circulation de trains permet de réduire l'intervalle de temps moyen entre deux trains consécutifs, les ressources du réseau ferroviaire ne sont toutefois pas partageables entre plusieurs trains. Autrement dit, lorsqu'une ressource du réseau est allouée à un train, elle ne peut plus être allouée à un autre train.If such a train traffic management facility can reduce the average time interval between two consecutive trains, the rail network resources are not shareable between several trains. In other words, when a network resource is allocated to a train, it can no longer be allocated to another train.

La donnée D indique la possibilité de partage, pour chacune des extrémités de la ressource voie associée à la table de consignation 20, de ladite ressource voie avec un autre train, conformément aux contraintes de circulation programmées pour le train 12 au sein de son contrôleur de bord 18. Chaque bulletin de consignation électronique 196 est caractérisé par un identifiant unique.Each
Les moyens de lecture 186, lorsqu'ils sont exécutés, génèrent une requête de lecture du contenu d'une table de consignation à double-entrée 20.The reading means 186, when executed, generate a request to read the contents of a double-entry log table 20.
Les moyens de vérification 187, lorsqu'ils sont exécutés, déterminent si les ressources voie d'une liste 194 sont effectivement consignées par le train 12, et si, parmi ces ressources voie, les aiguilles se trouvent commandées dans la position requise. Les moyens de vérification 187 sont propres à lire le contenu d'une base de données stockée au sein des moyens de mémorisation 180. Ils sont en outre propres à calculer une autorité de mouvement pour le train 12.The verification means 187, when executed, determine whether the resources of a list 194 are actually recorded by the
Les moyens d'estimation 188 sont aptes à déterminer au moins un profil de vitesse sur un chemin correspondant à un groupe de ressources voie potentielles. A partir de ce profil de vitesse, les moyens 188 sont aptes à estimer les instants de passage du train en des points particuliers de ce chemin. En fonction de ces instants de passage, les moyens d'identification 184 déterminent le créneau horaire sur lequel chaque ressource voie doit être consignée par le train. Le créneau horaire ainsi requis prend avantageusement en compte des marges de sécurité adaptées, en particulier le temps nécessaire à la consignation de la ressource voie, et éventuellement à la commande et au contrôle de la ressource voie si la ressource voie est une aiguille.The estimation means 188 are able to determine at least one speed profile on a path corresponding to a group of potential route resources. From this velocity profile, the
Chaque table de consignation 20 est caractérisée par un identifiant unique, sur le réseau 1. Avantageusement, chaque table de consignation 20 est caractérisée par un identifiant identique à celui de la ressource voie à laquelle elle est associée.Each log table 20 is characterized by a unique identifier, on the
En outre, chaque table de consignation 20 comporte un numéro de version courante. Chaque ROC 16 à l'intérieur duquel est installée une table 20 est propre à incrémenter le numéro de version courante de ladite table.In addition, each log table 20 has a current version number. Each
En variante de réalisation, toutes les tables de consignation 20 sont localisées dans une base de données centralisée, installée à demeure dans un lieu fixe du réseau 1. La base de données centralisée comporte des moyens de communication radio permettant d'établir une liaison sans fil avec les moyens de communication radio 182 équipant le contrôleur de bord 18 d'un train 12 ainsi qu'avec les moyens de communication radio 160 des ROC 16. Ces moyens de communication radio permettent ensuite d'échanger, sur la liaison sans fil établie, des messages selon un protocole de communication prédéterminé.As an alternative embodiment, all the log tables 20 are located in a centralized database, permanently installed in a fixed location of the
Le procédé de gestion de la circulation des trains 12 sur le réseau 1 mis en oeuvre par l'installation 15 va maintenant être décrit en regard des
Comme illustré sur la
A l'instant présent, le train 12 circule sur un chemin du réseau ferroviaire 1 décrit par une liste 194a mémorisée par le contrôleur de bord 18. Ce chemin courant comporte par exemple les ressources voie 2 et 3.At the present moment, the
Lors d'une étape 202 d'identification, les moyens d'identification 184 sont exécutés. Ils utilisent le fichier de course 192, la base de données 190 de description des ressources voie constitutives du réseau 1, la localisation instantanée du train 12 délivrée par les moyens 183 d'acquisition de caractéristiques dynamiques, pour générer un groupe de ressources voie potentielles. Les moyens d'identification 184 appellent les moyens d'estimation 188 pour élaborer à partir de ce groupe de ressources voie potentielles et pour un prochain créneau horaire requis, un groupe de ressources voie identifiées comme permettant au train de poursuivre sa course en empruntant le chemin correspondant à ces ressources voie, à condition que celles-ci soient consignées par le train 12 et soient placées dans un état de consignation requis. Les moyens d'identification 184 génèrent alors une liste 194b correspondant à ce groupe de ressources voie identifiées.During an
Dès que la liste 194b a été placée dans les moyens de mémorisation 180 du contrôleur de bord 18, les moyens de lecture 186 sont exécutés lors d'une étape 204 d'élaboration de messages de requête de lecture. Les moyens 186 élaborent autant de requêtes que de ressources voie dans la liste 194b. Chaque requête comporte l'identifiant du train requérant et l'identifiant de la ressource voie requise. Les moyens de communication 182 du contrôleur de bord 18, commandés par les moyens 186, émettent des signaux radio correspondant aux différentes requêtes de lecture.As soon as the
Les moyens de communication 160 des ROC 16 associés aux ressources voie identifiées captent les différents signaux radio reçus et ne transmettent à leur table de consignation 20 que les messages comportant l'identifiant de ladite table de consignation.The means of
Pour chaque ROC 16 associé à une ressource voie identifiée, les moyens de traitement 166 élaborent un message de réponse à la requête de lecture. Cette réponse comporte l'identifiant du train requérant, l'identifiant de la ressource voie requise, le numéro de version courante de la table 20 et le contenu de la table 20.For each
Si la table 20 est vide, le contenu retourné comporte la valeur « NULL ». Si la table 20 contient un bulletin de consignation électronique 196A créé par exemple par le contrôleur de bord 18A d'un train 12A, le contenu retourné comporte l'identifiant de l'entrée de la table 20 dans laquelle le bulletin 196A a été créé, ainsi que la donnée D du bulletin 196A.If the table 20 is empty, the returned content has the value "NULL". If the table 20 contains an electronic consignment note 196A created for example by the on-board controller 18A of a train 12A, the returned content includes the identifier of the entry of the table 20 in which the bulletin 196A has been created, as well as the data D of the 196A bulletin.
Les moyens de communication 160 émettent un signal radio correspondant à cette réponse. Les moyens de communication 182 du contrôleur de bord 18 captent et décodent les différents signaux qui leur parviennent, et ne transmettent aux moyens de mémorisation 180 que les messages qui comportent l'identifiant du train 12.The communication means 160 transmit a radio signal corresponding to this response. The communication means 182 of the on-
Les moyens de mémorisation 180 stockent le contenu des messages transmis par les moyens de communication 182.The storage means 180 store the contents of the messages transmitted by the communication means 182.
Pour une ressource voie identifiée donnée, dès que le message retourné a été placé dans les moyens de mémorisation 180, les moyens de vérification 187 sont exécutés lors d'une étape 206.For a given identified channel resource, as soon as the returned message has been placed in the storage means 180, the verification means 187 are executed in a
Si à l'issue de l'étape 206, le contenu de la table 20 associée à la ressource voie est différent de la valeur « NULL », les moyens de vérification 187 utilisent dans une étape 208 l'identifiant de l'entrée de la table 20 retourné ainsi que la donnée D, afin de déterminer si la ressource voie peut être empruntée par le train 12. Concrètement, les moyens de vérification 187 comparent les contraintes de circulation du train 12, c'est-à-dire principalement l'entrée par laquelle le train 12 se présente à la ressource voie, aux contraintes de circulation du train 12A indiquées au sein de la donnée D. Si ces contraintes sont compatibles, la ressource voie sera partagée entre le train 12 et le train 12A. Sinon, le contrôleur de bord 18 se met, à l'étape 210, en attente de libération de la ressource voie par le contrôleur de bord 18A. Les moyens 185 de consignation/autorisation/libération de ressources mettent à jour le champ de consignation de cette ressource voie en y écrivant la valeur « non-allouée » (0). L'étape 206 est ensuite ré-effectuée.If at the end of
Si à l'issue de l'étape 206, le contenu de la table 20 est la valeur « NULL » ou si, lors de l'étape 208, il a été déterminé que la ressource voie était partageable, les moyens d'identification 184 sont exécutés dans une étape 212. A l'étape 212, les moyens d'identification 184 déterminent la nature de la ressource voie.If at the end of
Si à l'issue de l'étape 212, la ressource voie est identifiée comme n'étant pas une aiguille, les moyens 185 de consignation/autorisation/libération de ressources sont exécutés lors d'une étape 214. Les moyens 185 élaborent un message de consignation de la ressource voie. La requête en consignation comporte l'identifiant du train requérant, l'identifiant de la ressource voie requise, le numéro de version mémorisé de la table 20 associée à la ressource voie, l'identifiant de l'entrée de la table 20 correspondant à l'extrémité de la ressource voie que le train 12 s'apprête à franchir, ainsi que la donnée D. Les moyens de communication 182 du contrôleur de bord 18, commandés par les moyens 185, émettent un signal radio correspondant à la requête en consignation de ressource.If at the end of
Si à l'issue de l'étape 212, la ressource voie est identifiée comme étant une aiguille, les moyens 185 de consignation/autorisation/libération de ressources sont exécutés lors d'une étape 216.If at the end of
Cette étape est illustrée en détail sur la
A l'étape 216b, les moyens de traitement 166 vérifient si l'aiguille est consignée en position inverse par un autre train. Cette information de consignation est obtenue par les moyens de traitement 166 par consultation du champ de consignation figurant dans la table d'état 164.In
Si l'aiguille est consignée en position inverse par un autre train, les moyens de traitement 166 élaborent, à l'étape 216c, un message de réponse à la commande. Cette réponse comporte l'identifiant du train requérant, l'identifiant de l'aiguille requise et l'état de commande instantané de l'aiguille lu dans la table d'état 164. Les moyens de communication 160 du ROC 16 émettent un signal radio correspondant à la réponse à la commande.If the needle is recorded in the opposite position by another train, the processing means 166 develop, in
Si l'aiguille n'est pas consignée en position inverse par un autre train, les moyens de traitement 166 vérifient, à l'étape 216d, si l'aiguille est verrouillée en position inverse. Cette information de verrouillage est obtenue par les moyens de traitement 166 par consultation du champ de verrouillage figurant dans la table d'état 164.If the needle is not recorded in the reverse position by another train, the processing means 166 verify, in
Si l'aiguille est verrouillée en position inverse, l'étape 216c est effectuée.If the needle is locked in the reverse position,
Si l'aiguille n'est pas verrouillée en position inverse, les moyens de traitement 166 comparent, à l'étape 216e, les paramètres de l'état de commande requis avec les paramètres de l'état de commande instantané de l'aiguille indiqués dans le champ de commande de la table d'état 164.If the needle is not locked in the reverse position, the processing means 166 compare, in
Si les paramètres de l'état de commande instantané de l'aiguille sont identiques aux paramètres de l'état de commande requis, l'étape 216c est effectuée.If the parameters of the instantaneous control state of the needle are identical to the parameters of the required control state,
Si les paramètres de l'état de commande instantané de l'aiguille sont différents des paramètres de l'état de commande requis, les moyens de traitement 166 vérifient, à l'étape 216f, si l'aiguille est consignée ou verrouillée en position inverse.If the parameters of the instantaneous control state of the needle are different from the parameters of the required control state, the processing means 166 verify, in
Si l'aiguille est consignée ou verrouillée en position inverse, l'étape 216c est effectuée.If the needle is recorded or locked in the reverse position,
Si l'aiguille n'est ni consignée ni verrouillée en position inverse, les moyens de traitement 166 commandent, à l'étape 216g, les moyens de pilotage 162 de l'organe 10 associé à l'aiguille, conformément aux paramètres de l'état de commande requis. L'organe 10 modifie la valeur du paramètre caractéristique correspondant suivant l'état requis. Les moyens de pilotage 162 modifient dans le champ de commande l'état de commande instantané de l'aiguille. L'étape 216c est ensuite effectuée.If the needle is not recorded or locked in the reverse position, the processing means 166 control, in
A l'issue de l'étape 216c, les moyens de communication 182 du contrôleur de bord 18 captent et décodent les différents signaux qui leur parviennent, et ne transfèrent aux moyens de consignation/autorisation/libération 185 que les messages qui comportent l'identifiant du train 12.At the end of
Lorsque la réponse en commande indique que l'aiguille a été placée selon les paramètres de commande requis, les moyens 185 écrivent dans le champ de commande correspondant à cette aiguille la valeur « 1 ». Sinon, les moyens 185 écrivent dans le champ de commande correspondant à cette aiguille la valeur « 0 ».When the command response indicates that the needle has been placed according to the required control parameters, the
A l'issue d'une durée prédéterminée après l'émission de la requête en commande, les moyens de vérification 187 sont exécutés lors d'une étape 216h pour vérifier si l'aiguille a effectivement été commandée conformément aux paramètres de commande requis. Les moyens 187 testent alors la valeur du champ de commande de l'aiguille. Si la valeur du champ de commande est égale à « 1 », l'étape 214 est effectuée. Sinon, le contrôleur de bord 18 active à l'étape 216i le freinage de service du train 12 dès que l'aiguille correspond à la prochaine ressource à emprunter par le train 12. L'étape 216a est ensuite ré-effectuée.At the end of a predetermined time after the transmission of the request for control, the verification means 187 are executed during a
A l'issue de l'étape 214,_les moyens de communication 160 du ROC 16 associé à la ressource voie captent et décodent les différents signaux radio reçus. Les moyens 160 extraient du message comportant l'identifiant de la table de consignation 20 le numéro de version de ladite table. Les moyens de traitement 166 sont alors exécutés et comparent le numéro de version de la table 20 reçu au numéro de version courante de la table 20.At the end of
Si les deux numéros sont identiques, les moyens 160 transmettent le message à la table de consignation 20 du ROC 16. Selon l'identifiant de l'entrée de la table 20 reçu, la table 20 crée, lors d'une étape 218, un bulletin de consignation électronique 196 sur l'entrée correspondante. Le bulletin de consignation électronique comporte la donnée D. Les moyens de traitement 166 incrémentent le numéro de version courante de la table 20 et écrivent dans le champ de consignation de la table d'état 164 la valeur « 1 ». Les moyens de traitement 166 élaborent un message de réponse en consignation de ressource. Cette réponse comporte l'identifiant du train requérant, l'identifiant de la ressource voie requise, le numéro de version courante de la table 20 associée à la ressource voie, ainsi que l'identifiant du bulletin de consignation électronique 196 créé. Les moyens de communication 160 du ROC 16 émettent un signal radio correspondant à la réponse en consignation de ressource. Les moyens de communication 182 du contrôleur de bord 18 captent et décodent les différents signaux qui leur parviennent, et ne transmettent aux moyens de mémorisation 180 que les messages qui comportent l'identifiant du train 12.If the two numbers are identical, the
Lorsque la réponse en consignation indique que la ressource voie requise a effectivement été allouée au train 12, les moyens 185 de consignation/autorisation/libération de ressources mettent à jour le champ de consignation correspondant à cette ressource voie dans la liste 194b. La valeur « allouée » (+1) est écrite dans le champ de consignation de la ressource voie.When the consignment response indicates that the required channel resource has indeed been allocated to the

Cette étape est illustrée en détail sur la
Si la ressource voie est une aiguille, les moyens 185 de consignation/autorisation/li bération élaborent un message de requête d'autorisation de la ressource voie au cours d'une étape 219b. La requête d'autorisation comporte l'identifiant du train requérant et l'identifiant de l'aiguille requise. Les moyens de communication 182 du contrôleur de bord 18, commandés par les moyens 185, émettent un signal radio correspondant à la requête d'autorisation. Les moyens de communication 160 du ROC 16 associé à l'aiguille captent et décodent les différents signaux radio reçus et transmettent aux moyens de traitement 166 le message comportant l'identifiant du ROC 16.If the channel resource is a pointer, the
A l'issue de l'étape 219b, les moyens de pilotage 162 du ROC 16 associé à l'aiguille commandent, à l'étape 219c, l'organe 10 associé à l'aiguille. L'organe 10 transmet aux moyens de pilotage 162 la valeur courante du paramètre caractéristique de la position de l'aiguille. Les moyens de pilotage 162 mettent à jour la table d'état 164 et les moyens de traitement 166 lisent la valeur courante du paramètre dans la table d'état 164.At the end of the
Si la valeur courante du paramètre indique que l'aiguille n'est pas commandée dans la position requise, les moyens de pilotage 162 sont exécutés pour vérifier, à l'étape 219d, si l'organe 10 associé à l'aiguille est en défaut.If the current value of the parameter indicates that the needle is not controlled in the required position, the control means 162 are executed to verify, in
Si l'organe 10 n'est pas en défaut, l'étape 219c est ré-effectuée.If the
Si l'organe 10 est en défaut, les moyens de pilotage 162 mettent à jour la table d'état 164. Les moyens de traitement 166 élaborent alors un message de réponse négatif à la requête d'autorisation. Ce message comporte en outre l'identifiant du train requérant, l'identifiant de l'aiguille requise et l'état de consignation instantané de l'aiguille lu dans la table d'état 164. Les moyens de communication 160 du ROC 16 émettent un signal radio correspondant à la réponse à la requête d'autorisation.

Si la valeur courante du paramètre indique que l'aiguille est commandée dans la position requise, les moyens de pilotage 162 sont exécutés pour vérifier, à l'étape 219f, si l'aiguille est protégée par une aiguille en protection.If the current value of the parameter indicates that the needle is controlled in the required position, the control means 162 are executed to verify, in
Si l'aiguille n'est pas protégée par une aiguille en protection, les moyens de traitement 166 élaborent, à l'étape 219g, un message de réponse positive à la requête d'autorisation. Ce message comporte en outre l'identifiant du train requérant et l'identifiant de l'aiguille requise. Les moyens de communication 160 du ROC 16 émettent un signal radio correspondant à la réponse à la requête d'autorisation.

A l'étape 220g, les moyens de vérification 187 calculent, en fonction notamment de la localisation du train 12 et de la localisation de la queue du train 12B précédent, une nouvelle autorité de mouvement pour le train 12. Ce calcul est effectué selon un algorithme connu en soi, et tel que décrit par exemple dans le document
Si, à l'issue de l'étape 220g, la localisation de la queue du train 12B précédent est située en deçà de la localisation de l'autre entrée de la ressource, l'étape 220f est ré-effectuée. Sinon, l'étape 220c est effectuée.If, at the end of
A l'issue de l'étape 220c, les moyens 185 de consignation/d'autorisation/de libération de ressources sont exécutés lors d'une étape 222. Les moyens 185 élaborent un message de libération de la ressource. La requête en libération comporte l'identifiant du train requérant, l'identifiant de la ressource à libérer, le numéro de version mémorisé de la table 20 associée à la ressource, ainsi que l'identifiant mémorisé du bulletin de consignation électronique 196 créé dans la table 20. Les moyens de communication 182 du contrôleur de bord 18, commandés par les moyens 185, émettent un signal radio à destination du ROC 16 associé à la ressource. Le signal radio correspond à la requête en libération de ressource. Les moyens de communication 160 du ROC 16 associé à la ressource captent et décodent le signal radio. Les moyens 160 extraient du message comportant l'identifiant de la table de consignation 20 le numéro de version de ladite table. Les moyens de traitement 166 sont alors exécutés et comparent le numéro de version de la table 20 reçu au numéro de version courante de la table 20.At the end of
Si les deux numéros sont identiques, les moyens 160 transmettent le message à la table de consignation 20 du ROC 16. La table 20 supprime, lors d'une étape 224, le bulletin de consignation électronique 196 dont l'identifiant correspond à l'identifiant transmis dans le message. Les moyens de traitement 166 incrémentent le numéro de version courante de la table 20.If the two numbers are identical, the
Seulement à cet instant, la ressource voie est libérée si aucun autre bulletin de consignation électronique n'est présent dans la table 20.Only at this time, the channel resource is released if no other electronic logging report is present in table 20.
Les moyens de traitement 166 élaborent un message de réponse en libération de ressource. Cette réponse comporte l'identifiant du train requérant, l'identifiant de la ressource libérée, le numéro de version courante de la table 20 associée à la ressource, ainsi que la confirmation que le bulletin de consignation électronique 196 a été supprimé. Les moyens de communication 160 du ROC 16 émettent un signal radio correspondant à la réponse en libération de ressource, à destination du contrôleur de bord 18 du train 12. Les moyens de communication 182 du contrôleur de bord 18 captent et décodent les différents signaux qui leur parviennent, et ne transmettent aux moyens de mémorisation 180 que les messages qui comportent l'identifiant du train 12. Lorsque la réponse en libération indique que la ressource a été libérée, les moyens 185 de consignation/d'autorisation/de libération de ressources écrivent dans le champ de consignation de cette ressource la valeur « libérée » (+2).The processing means 166 develop a response message in resource release. This response includes the identifier of the requesting train, the identifier of the released resource, the current version number of the table associated with the resource, as well as the confirmation that the
L'étape 202 est alors ré-effectuée et les moyens d'identification 184 génèrent une nouvelle liste 194c correspondant à un nouveau groupe de ressources voie identifiées.Step 202 is then re-performed and the identification means 184 generate a
Si les deux numéros sont différents, le message est rejeté par les moyens de communication 160 du ROC 16, et l'étape 202 est ré-effectuée.If the two numbers are different, the message is rejected by the communication means 160 of the
Dans ce procédé, une ressource voie du réseau 1 est partageable entre deux trains, à condition que les conditions d'accès à cette ressource voie par les deux trains soient compatibles entre elles.In this method, a
On conçoit ainsi que l'installation de gestion de la circulation de trains selon l'invention permet de réduire sensiblement l'intervalle de temps moyen entre deux trains consécutifs.It is thus conceivable that the train circulation management installation according to the invention makes it possible to substantially reduce the average time interval between two consecutive trains.
En variante, l'étape 204 est effectuée avant l'étape 202, autrement dit les moyens d'identification 184 mettent en oeuvre une étape initiale de lecture des tables de consignation 20 présentes dans l'environnement du train 12 pour connaître l'état de consignation des ressources voie associées. Cette mise en oeuvre peut avantageusement s'effectuer par un protocole d'échange de messages de requête et de réponse similaire aux protocoles décrits précédemment. La connaissance préalable de l'état de consignation des ressources voie potentielles facilite l'identification proprement dite d'un groupe de ressources voie identifiées.As a variant, the
