Description

L'invention concerne un procédé de contrôle de l'état d'une voie ferrée et a plus particulièrement pour objet le repérage des défauts relevés par des équipements de contrôle embarqués sur une voiture roulant sur la voie ferrée à contrôler pour permettre aux équipes de maintenance de retrouver ultérieurement ces défauts; l'invention concerne aussi un système de contrôle pour la mise en oeuvre de ce procédé.The invention relates to a method for checking the condition of a railway track and more particularly relates to the identification of faults detected by control equipment on board a car traveling on the railway track to be checked to allow maintenance teams to subsequently find these faults; the invention also relates to a control system for the implementation of this method.

Il est connu de contrôler une voie ferrée en faisant circuler sur celle-ci une voiture spéciale comportant des appareils de contrôle de toutes sortes, notamment des systèmes à ultrasons et des capteurs à courant de Foucault.It is known practice to control a railway by running a special car on it comprising control devices of all kinds, in particular ultrasonic systems and eddy current sensors.

Tous ces moyens de contrôle sont mis en oeuvre pour détecter, au fur et à mesure de la progression de la voiture, des types de défaut spécifiques : fissures internes pour les détecteurs à ultrasons, fissures débouchant en surface de la table de roulement pour les détecteurs à courant de Foucault, etc... Un système de traitement informatique est également embarqué pour traiter les informations délivrées par tous les capteurs, les corréler et caractériser ainsi la nature du défaut tout en distinguant parmi les signaux reçus ceux qui correspondent à un point singulier (joint ou rail éclissé, joint soudé) et non à un défaut.All of these control means are used to detect, as the car progresses, specific types of fault: internal cracks for the ultrasonic detectors, cracks opening onto the surface of the tread for the detectors eddy current, etc ... A computer processing system is also on board to process the information delivered by all the sensors, correlate them and thus characterize the nature of the fault while distinguishing among the signals received those which correspond to a singular point (joint or rail jointed, joint welded) and not a defect.

D'autres informations relatives à l'état général de la voie ferrée peuvent être rassemblées par des moyens adaptés et traitées par l'ordinateur, commepar exemple la stabilité de la voie ou encore la qualité du shuntage des rails par les essieux qui conditionne le fonctionnement automatique des signaux.Other information relating to the general condition of the railway track can be gathered by suitable means and processed by the computer, such as for example the stability of the track or the quality of the shunting of the rails by the axles which conditions the operation. automatic signals.

L'ordinateur est associé à des moyens d'enregistrement et d'affichage de toutes ces informations, comme par exemple une imprimante qui délivre une succession de messages qui seront exploités ultérieurement par une équipe de maintenance. Un opérateur surveillant la prise des données peut également, par l'intermédiaire d'un clavier, inscrire des informations indiquant des points singuliers de la voie (tunnels, aiguillages) facilitant le repérage des défauts par l'équipe de maintenance.The computer is associated with means for recording and displaying all this information, such as for example a printer which delivers a succession of messages which will be used subsequently by a maintenance team. An operator supervising the taking of data can also, via a keyboard, enter information indicating singular points of the track (tunnels, switches) facilitating the identification of faults by the maintenance team.

Par ailleurs, le repérage précis d'un défaut est assuré par un marquage de peinture commandé automatiquement depuis la voiture par le système de contrôle. Cependant ces traces de peinture sont assez difficiles à retrouver si les informations enregistrées ne comportent pas un nombre suffisant de points singuliers précités.In addition, the precise identification of a defect is ensured by a paint marking automatically controlled from the car by the control system. However, these traces of paint are quite difficult to find if the information recorded does not contain a sufficient number of singular points mentioned above.

Or l'automatisation de la détection des défauts et l'amélioration des performances des appareillages correspondants permet d'envisager la réduction des temps de contrôle, en augmentant la vitesse de la voiture portant ces équipements. Il devient alors très difficile pour l'opérateur de noter clairement et avec précision la nature et l'emplacement de tous les points singuliers qu'il repère. L'invention a pour but de permettre une saisie automatique des points singuliers facilitant la localisation des marques de peinture.However, the automation of fault detection and the improvement of the performance of the corresponding equipment makes it possible to envisage a reduction in control times, by increasing the speed of the car carrying this equipment. It then becomes very difficult for the operator to note clearly and precisely the nature and location of all the singular points he spots. The invention aims to allow automatic entry of singular points facilitating the location of paint marks.

Plus précisément, l'invention concerne donc un procédé de contrôle de l'état d'une voie ferrée du type consistant à déplacer les moyens de contrôle sur une voiture roulant sur ladite voie et à enregistrer les signaux émis par lesdits moyens de contrôle au fur et à mesure de la progression de ladite voiture, caractérisé en ce qu'il consiste, en pointant un radar embarqué sur ladite voiture vers des structures caractéristiques situées le long de ladite voie, à enregistrer les signaux d'écho correspondants, simultanément auxdits signaux, pour contribuer au repérage ultérieur des défauts détectés sur ladite voie ferrée.More specifically, the invention therefore relates to a method for checking the condition of a railway track of the type consisting in moving the control means on a car traveling on said track and in recording the signals emitted by said control means and as the progress of said car progresses, characterized in that it consists, by pointing a radar on board of said car towards characteristic structures located along said track, at recording the corresponding echo signals, simultaneously with said signals, to contribute to the subsequent identification of the faults detected on said railway.

Parmi les structures caractéristiques repérables par ce moyen, on peut citer les ponts, les tunnels et surtout les poteaux caténaires qui présentent l'avantage de procurer des échos bien caractéristiques constituant un balisage relativement précis de la voie ferrée puisqu'ils sont disposés à intervalles réguliers sur la quasi totalité des parcours électrifiés.Among the characteristic structures that can be identified by this means, we can cite bridges, tunnels and above all catenary poles, which have the advantage of providing very characteristic echoes constituting a relatively precise marking of the railway since they are arranged at regular intervals. on almost all electrified routes.

L'invention concerne également un système de contrôle d'une voie ferrée comportant une voiture roulant sur ladite voie dans laquelle sont installés des moyens de contrôle en continu de ladite voie et des moyens d'enregistrement des signaux délivrés par lesdits moyens de contrôle caractérisé en ce que ladite voiture porte au moins un équipement radar dont l'antenne est orientée dans une direction prédéterminée correspondant à la position de structures caractéristiques situées au voisinage de la voie et ce que lesdits moyens d'enregistrement sont connectés pour enregistrer les signaux d'écho élaborés par le radar correlativement aux signaux délivrés par les moyens de contrôle.The invention also relates to a system for controlling a railway track comprising a car traveling on said track in which are installed means for continuously monitoring said track and means for recording the signals delivered by said control means, characterized in that said car carries at least one radar device whose antenna is oriented in a predetermined direction corresponding to the position of characteristic structures located in the vicinity of the track and that said recording means are connected to record the echo signals developed by the radar correlatively to the signals delivered by the control means.

L'invention apparaîtra plus clairement ainsi que d'autres avantages de celle-ci, à la lumière de la description qui va suivre, donnée uniquement à titre d'exemple et faite en référence au dessin non limitatif annexé dans lequel :

  • - La figure 1 représente schématiquement une voiture de contrôle se déplaçant sur une voie ferrée en cours de contrôle, ladite voiture étant pourvue d'un équipement radar conforme à l'invention;
  • - La figure 2 est un schéma-bloc de l'installation; et
  • - La figure 3 illustre le mode de fonctionnement de l'équipement radar.
The invention will appear more clearly as well as other advantages thereof, in the light of the description which follows, given solely by way of example and made with reference to the attached nonlimiting drawing in which:
  • - Figure 1 shows schematically a control car moving on a railroad under control, said car being provided with radar equipment according to the invention;
  • - Figure 2 is a block diagram of the installation; and
  • - Figure 3 illustrates the operating mode of the radar equipment.

En se reportant au dessin, le système de contrôle décrit est installé à bord d'une voiture (11) se déplaçant sur une voie ferrée (12a) à contrôler. Deux alignements de poteaux caténaires (13a), (13b) sont respectivement établis le long de deux voies ferrées parallèles (12a), (12b). Un certain nombre de capteurs (14), (15), (16), (17) ... sont installés dans la voiture pour contrôler les rails. Ce sont principalement des capteurs à ultrasons ou à courant de Foucault, comme mentionné ci-dessus. Les signaux émis par ces capteurs sont traités et gérés par un ordinateur (20) qui pilote une imprimante (21) dont le rôle est d'enregistrer et visualiser les informations signalant les défauts et leur localisation approximative par des points singuliers. Certains de ces points singuliers peuvent être enregistrés directement par un opérateur inspectant la voie depuis la voiture (11). L'opérateur utilise alors un clavier (22) couplé au système ordinateur-imprimante. L'ordinateur pilote en outre un dispositif de marquage (23) projetant une petite quantité de peinture sur la voie ferrée chaque fois qu'un défaut est détecté par l'un des capteurs (14-17) et reconnu comme tel par l'ordinateur, selon des critères et une procédure d'analyse connus, qui ne font pas partie de l'invention.Referring to the drawing, the described control system is installed on board a car (11) moving on a railway track (12a) to be checked. Two alignments of catenary poles (13a), (13b) are respectively established along two parallel railways (12a), (12b). A number of sensors (14), (15), (16), (17) ... are installed in the car to control the rails. These are mainly ultrasonic or eddy current sensors, as mentioned above. The signals emitted by these sensors are processed and managed by a computer (20) which controls a printer (21) whose role is to record and display the information signaling the faults and their approximate location by singular points. Some of these singular points can be recorded directly by an operator inspecting the lane from the car (11). The operator then uses a keyboard (22) coupled to the computer-printer system. The computer also controls a marking device (23) projecting a small amount of paint onto the railway each time a fault is detected by one of the sensors (14-17) and recognized as such by the computer , according to known criteria and analysis procedure, which are not part of the invention.

Selon l'invention, la voiture (11) porte à sa partie supérieure, au moins une et de préférence deux antennes de radar (25a), (25b), ici sous forme de paraboloides.According to the invention, the car (11) carries at its upper part, at least one and preferably two radar antennas (25a), (25b), here in the form of satellite dishes.

Ces antennes sont orientées dans des directions prédéterminées (symétriquement de part et d'autre de la voiture et vers l'avant) correspondant à la position possible de structures caractéristiques situées au voisinage de la voie. Selon l'exemple, l'antenne (25a) est pointée en direction de la partie haute des poteaux caténaires (13a) et reçoit les échos correspondants tandis que les signaux éventuellement émis par l'antenne (25b) ne donnent lieu à aucun écho exploitable. En revanche, si la voiture circulait sur la voie ferrée (12b), la situation serait inversée, l'antenne (25b) fournissant les signaux d'écho représentatifs de la présence des caténaires (13b).These antennas are oriented in predetermined directions (symmetrically on either side of the car and towards the front) corresponding to the possible position of characteristic structures located in the vicinity of the track. According to the example, the antenna (25a) is pointed towards the upper part of the catenary poles (13a) and receives the corresponding echoes while the signals possibly emitted by the antenna (25b) do not give rise to any usable echo . On the other hand, if the car was traveling on the railway (12b), the situation would be reversed, the antenna (25b) providing the echo signals representative of the presence of the catenary (13b).

Dans tous les cas c'est donc l'alignement des poteaux caténaires le plus proche de la voiture (11) qui est détecté. Chaque antenne (25a), (25b) est orientée pour que son faisceau radar soit plus particulièrement dirigé vers les antibalançants (26) des poteaux caténaires de l'alignement correspondant. L'équipement radar connecté aux antennes est classique et comporte des moyens de mesure de l'effet Doppler résultant du déplacement de la voiture (11). En effet, l'orientation de l'antenne étant fixée et l'écartement b des poteaux caténaires par rapport à la voie ferrée variant peu, la distance d séparant les antibalançants des poteaux caténaires de l'antenne lors de l'élaboration de l'écho (voir figure 3) est une constante et la variation de fréquence fo correspondante est connue si la vitesse de la voiture (11) est stabilisée à une valeur prédéterminée (de l'ordre de 40 km/h dans la pratique).In all cases, it is therefore the alignment of the catenary poles closest to the car (11) which is detected. Each antenna (25a), (25b) is oriented so that its radar beam is more particularly directed towards the anti-balancers (26) of the catenary poles of the corresponding alignment. The radar equipment connected to the antennas is conventional and includes means for measuring the Doppler effect resulting from the movement of the car (11). In fact, the orientation of the antenna being fixed and the spacing b of the catenary poles relative to the railway track varying little, the distance d separating the anti-balancers from the catenary poles of the antenna during the preparation of the echo (see Figure 3) is a constant and the corresponding frequency variation fo is known if the speed of the car (11) is stabilized at a predetermined value (in the order of 40 km / h in practice).

Le système peut donc comporter par exemple un générateur HF (28) relié à un dispositif d'émission-réception (29) dont la sortie de signal d'écho est reliée à des moyens comparateurs de fréquences (30) également connectés au générateur (28). Tout écart de fréquence fo prédéterminé est interprété comme la détection d'un poteau caténaire et provoque la transmission d'un ordre de pilotage de l'imprimante (21). Le système est programmé pour corriger automatiquement la localisation du caténaire de la distance a due à l'orientation vers l'avant de l'antenne (voir figure 3). Une fois cette correction d'erreur systématique effectuée, l'erreur résiduelle de localisation ne dépend pratiquement que des variations de l'éloignement des antibalançants de poteaux caténaires par rapport à la voie (distance b); elle est de l'ordre de 1 à 2 mètres. Bien entendu, on pourrait prévoir d'autres antennes (25) pointées vers d'autres structures caractéristiques comme les ponts et les tunnels.The system can therefore include, for example, an HF generator (28) connected to a transceiver device (29), the echo signal output of which is connected to frequency comparator means (30) also connected to the generator (28). ). Any predetermined frequency difference fo is interpreted as the detection of a catenary pole and causes the transmission of a command to control the printer (21). The system is programmed to automatically correct the location of the catenary of the distance a due to the forward orientation of the antenna (see Figure 3). Once this systematic error correction has been made, the residual location error practically depends only on variations in the distance of the anti-balancers from the catenary poles relative to the track (distance b); it is of the order of 1 to 2 meters. Of course, one could provide other antennas (25) pointed towards other characteristic structures such as bridges and tunnels.
