Description

La présente invention concerne un dispositif de confirmation d'intégrité d'un attelage d'un convoi ferroviaire comprenant au moins une première voiture et une deuxième voiture, le dispositif comprenant un support de communication s'étendant entre la première voiture et la deuxième voiture, une première balise embarquée à bord de l'une des voitures et reliée au support de communication, une deuxième balise embarquée à bord de l'autre des voitures et reliée au support de communication.The present invention relates to a device for confirming the integrity of a hitch of a railway train comprising at least a first car and a second car, the device comprising a communication medium extending between the first car and the second car, a first beacon embedded in one of the cars and connected to the communication medium, a second beacon embedded on board the other cars and connected to the communication medium.

L'invention s'applique au domaine de la sécurité ferroviaire, notamment à la confirmation d'intégrité d'un convoi ferroviaire.The invention applies to the field of railway safety, in particular to the confirmation of integrity of a railway train.

Par « confirmation d'intégrité », on entend au sens de la présente demande la détection de la non-rupture d'un attelage du convoi ferroviaire, c'est-à-dire la non-rupture de la liaison mécanique entre deux wagons ou deux voitures d'un convoi ferroviaire, que celle-ci soit « à vis », automatique ou de n'importe quel autre type d'accouplement.For the purposes of this application, the term "confirmation of integrity" means the detection of the non-rupture of a coupling of the railway train, that is to say the non-breaking of the mechanical connection between two wagons or two cars of a railway train, whether it is "screw", automatic or any other type of coupling.

Il est connu d'utiliser un émetteur pour générer un signal au niveau d'une première voiture d'un convoi ferroviaire, située en queue de convoi, et d'appliquer ce signal, successivement au cours du temps et sous la forme d'une onde acoustique, à une conduite de pression du convoi ferroviaire.It is known to use a transmitter to generate a signal at a first car of a train convoy, located at the tail of the convoy, and to apply this signal, successively over time and in the form of a signal. acoustic wave, to a pressure line of the railway convoy.

Un récepteur, disposé à bord d'une deuxième voiture du convoi ferroviaire, située en tête du convoi, est propre à recevoir l'onde acoustique générée par l'émetteur et se propageant dans la conduite de pression.A receiver, placed on board a second car of the train convoy, located at the head of the convoy, is adapted to receive the acoustic wave generated by the transmitter and propagating in the pressure line.

En cas de rupture d'attelage, l'onde acoustique ne peut pas se propager entre l'émetteur et le récepteur le long de la conduite de pression. Le récepteur, ne recevant plus l'onde acoustique générée par l'émetteur, détecte alors une rupture d'attelage au sein du convoi ferroviaire.In the event of a coupling failure, the acoustic wave can not propagate between the transmitter and the receiver along the pressure line. The receiver, no longer receiving the acoustic wave generated by the transmitter, then detects a coupling failure within the railway train.

Néanmoins, un tel dispositif ne donne pas entière satisfaction.Nevertheless, such a device does not give complete satisfaction.

En effet, l'onde acoustique émise par l'émetteur s'atténue au cours de sa propagation le long de la conduite de pression. Du fait de la longueur des convois ferroviaires, la puissance de l'onde acoustique parvenant au récepteur est susceptible d'être à un niveau similaire à celui du bruit aléatoire présent dans la conduite de pression et qui est également détecté par le détecteur. Il n'est alors pas possible d'affirmer avec un niveau de fiabilité suffisant que le signal détecté par le détecteur est l'onde acoustique qui a été émise par l'émetteur embarqué à bord de la première voiture. Ceci signifie qu'il n'est pas possible d'affirmer, avec un niveau de fiabilité suffisant, que le convoi ferroviaire est toujours intègre.Indeed, the acoustic wave emitted by the transmitter attenuates during its propagation along the pressure line. Because of the length of railway convoys, the power of the acoustic wave reaching the receiver is likely to be at a level similar to that of the random noise present in the pressure line and which is also detected by the detector. It is then not possible to state with a sufficient level of reliability that the signal detected by the detector is the acoustic wave that has been emitted by the onboard transmitter aboard the first car. This means that it is not possible to say, with a sufficient level of reliability, that the railway convoy is always intact.

Un but de l'invention est donc de proposer un dispositif qui permette de confirmer l'intégrité d'un convoi ferroviaire avec une meilleure fiabilité.An object of the invention is therefore to propose a device that makes it possible to confirm the integrity of a railway train with better reliability.

A cet effet, l'invention a pour objet un dispositif du type précité, dans lequel :

  • la deuxième balise est propre à générer un signal modulé par des données de codage prédéterminées et à appliquer le signal modulé au support de communication ;
  • le support de communication est propre à acheminer ledit signal vers la première balise, le support de communication étant en outre propre à se rompre en cas de rupture d'un attelage entre les deux voitures empêchant alors la propagation du signal jusqu'à la première balise ;
  • la première balise est propre à recevoir un signal acheminé par le support de communication et à extraire des données de codage extraites du signal reçu ;
le dispositif étant propre à confirmer l'intégrité d'un attelage entre les voitures du convoi ferroviaire si les données de codage extraites par la première balise sont identiques aux données de codage prédéterminées.For this purpose, the subject of the invention is a device of the aforementioned type, in which:
  • the second beacon is adapted to generate a signal modulated by predetermined coding data and to apply the modulated signal to the communication medium;
  • the communication medium is adapted to convey said signal to the first beacon, the communication medium being furthermore capable of breaking in the event of a breakage of a hitch between the two cars thus preventing the propagation of the signal until the first beacon ;
  • the first beacon is adapted to receive a signal conveyed by the communication medium and to extract coding data extracted from the received signal;
the device being able to confirm the integrity of a coupling between the cars of the railroad train if the coding data extracted by the first beacon are identical to the predetermined coding data.

En effet, il est possible de choisir un code de taille suffisante pour permettre au dispositif de détecter le code avec une fiabilité suffisante, c'est-à-dire discriminer le code reçu d'un code généré de façon aléatoire par le bruit, avec un taux d'erreur inférieur à un seuil souhaité.Indeed, it is possible to choose a code of sufficient size to allow the device to detect the code with sufficient reliability, that is to say, to discriminate the code received from a code randomly generated by the noise, with an error rate below a desired threshold.

L'émetteur 34 est propre à appliquer des signaux au support de communication 8. Dans le cas d'une conduite de pression formant le support de communication 8, l'émetteur 34 est propre à appliquer des ondes acoustiques.

The transmission software 40 is further adapted to transmit the signal generated to the transmitter 34.

En fonctionnement, le logiciel d'émission 40 de la balise émettrice 12 génère un signal modulé par le code prédéterminé qui est stocké dans la deuxième zone de stockage 42. Le code prédéterminé forme alors des données de codage. Puis l'émetteur 34 de la balise émettrice 12 applique le signal au support de communication 8.In operation, the transmission software 40 of the transmitting beacon 12 generates a signal modulated by the predetermined code which is stored in the second storage area 42.

Si le récepteur 16 de la balise de contrôle 10 reçoit un signal acheminé par le support de communication 8, alors le logiciel de réception 22 de la balise de contrôle 10 traite ledit signal pour en extraire un code. Puis le logiciel de comparaison 24 compare le code reçu au code prédéterminé qui est stocké dans la première zone de stockage 28. Si le code reçu est identique au code prédéterminé, alors le convoi ferroviaire 2 est considéré comme intègre et la balise de contrôle 10 émet un signal de confirmation d'intégrité du convoi ferroviaire, par exemple à destination d'un opérateur ou d'un système de surveillance du réseau ferroviaire.If the receiver 16 of the control beacon 10 receives a signal conveyed by the communication medium 8, then the receiving software 22 of the control beacon 10 processes said signal to extract a code.

La clé de contrôle forme alors les données de codage. L'émetteur 34 applique ledit signal au support de communication 8.In operation, the calculation software 48 of the transmitting beacon 12 calculates a control key relating to the predetermined code. Then the transmission software 40 of the transmitting beacon 12 transmits to the transmitter 34 a signal modulated by the predetermined code and the corresponding control key. The control key then forms the encoding data. The transmitter 34 applies said signal to the communication medium 8.

Si le récepteur 16 de la balise de contrôle 10 reçoit un signal acheminé par le support de communication 8, alors le logiciel de réception 22 de la balise de contrôle 10 traite ledit signal pour en extraire un code et une clé correspondante.

Le logiciel de comparaison 24 compare ensuite la clé extraite par le logiciel de réception 22 et la clé calculée par le logiciel de calcul 44. Si la clé calculée est identique à la clé extraite, alors le convoi ferroviaire 2 est considéré comme intègre et la balise de contrôle 10 émet un signal de confirmation d'intégrité du convoi ferroviaire, par exemple à destination d'un opérateur ou d'un système de surveillance du réseau ferroviaire.If the receiver 16 of the control beacon 10 receives a signal conveyed by the communication medium 8, then the reception software 22 of the control beacon 10 processes said signal to extract a code and a corresponding key. Then the calculation software 44 calculates a control key relating to the code extracted by the reception software 22, by means of the generator polynomial stored in the third storage area 46. The comparison software 24 then compares the key extracted by the software of 22 and the key calculated by the calculation software 44. If the calculated key is identical to the extracted key, then the railway train 2 is considered to be intact and the control beacon 10 emits a signal confirming the integrity of the train convoy for example to an operator or a monitoring system of the rail network.

Si, la clé calculée est différente de la clé extraite, ou si, à l'issue d'une durée d'attente prédéterminée, la balise de contrôle 10 ne reçoit pas de signal comprenant un code identique au code prédéterminé, alors la balise de contrôle 10 n'émet pas de signal de confirmation d'intégrité du véhicule ferroviaire.If, the calculated key is different from the key extracted, or if, after a predetermined waiting period, the control beacon 10 does not receive a signal comprising a code identical to the predetermined code, then the beacon of control 10 does not emit a signal confirming the integrity of the railway vehicle.
