Méthode et dispositif de contrôle de présence de rail.Method and device for monitoring the presence of rails
La présente invention concerne une méthode et un dispositif pour surveiller en temps réel l' enraillement correct d'une roue sur son rail, selon les préambules des revendications 1 et 6.The present invention relates to a method and a device for monitoring in real time the correct braking of a wheel on its rail, according to the preambles of claims 1 and 6.
En particulier, l'invention se rapporte à la détection et au contrôle de la présence d'un rail servant au guidage de véhicules guidés.In particular, the invention relates to the detection and control of the presence of a rail for guiding guided vehicles.
Les termes « véhicules guidés » font en particulier référence aux moyens de transports en commun tels que des bus, trolleybus, tramways, métros, trains ou unités de train, etc., pour lesquels l'aspect sécuritaire est très important et pour lesquels le guidage est assuré par au moins un rail. Bien que ces systèmes aient fonctionnes jusqu'ici sans détection d' enraillement ou de déraillement, les règlements de sécurités récents et à venir exigent un dispositif additionnel de sécurité lié à l' enraillement . En particulier, ledit rail sert de guide à ladite roue lors de son déplacement par rotation le long dudit rail, ladite roue pouvant être, par exem- pie, un galet.The term "guided vehicles" refers in particular to means of public transport such as buses, trolleybuses, trams, subways, trains or train units, etc., for which the safety aspect is very important and for which the guidance is provided by at least one rail. Although these systems have functioned to date without detection of a derailment or derailment, recent and future safety regulations require additional safety features related to the occurrence of the derailment. In particular, said rail serves as a guide for said wheel during its displacement by rotation along said rail, said wheel possibly being, for example, a roller.
Le document FR 2909061 Al (ou WO2008074942 Al) présente un dispositif de détection du risque de déraillement et d'évacuation de débris ou d'objets sur la voie de guidage par rail d'un véhicule. La détection du déraillement est basée sur la perte d'un contact électrique entre un patin et le rail, ladite perte de contact déclenchant alors un freinage d'urgence. Ledit patin est uniquement adapté pour une forme géométrique de rail afin de garantir le meilleur contact électrique possible avec ce dernier. D'autre part, ledit pa- tin est soumis à un environnement extérieur contraignant qui peut, à certaines occasions, nuire à la fiabilité de la détection, notamment lors de pertes du contact électrique malgré un enraillement correct. Toutefois, la présente invention ne concerne pas un modèle de détection adapté à une unique forme géométrique de rail, et permet de surmonter les défauts liés à la détection par contact électrique, notamment les problèmes liés au contact électrique lui-même, tout en obtenant d'autres avantages.FR 2909061 A1 (or WO2008074942 A1) discloses a device for detecting the risk of derailment and evacuation of debris or objects on the guide rail of a vehicle. The detection of the derailment is based on the loss of an electrical contact between a pad and the rail, said loss of contact then triggering an emergency braking. Said pad is only adapted for a geometric rail shape to ensure the best possible electrical contact with the latter. On the other hand, the said tin is subjected to a constraining external environment which can, on certain occasions, affect the reliability of the detection, in particular when the electrical contact is lost despite a correct braking. However, the present invention does not relate to a detection model adapted to a single geometrical shape of a rail, and makes it possible to overcome the defects related to the detection by electrical contact, in particular the problems related to the electrical contact itself, while at the same time obtaining 'other advantages.
Un but de la présente invention est de proposer une méthode et un dispositif simple, sûr et fiable, de sécurisation du guidage de véhicules guidés, idéalement, facilement adaptable à tout type de véhicule guidé par rail, indépendamment de la géométrie du rail.An object of the present invention is to provide a method and a simple device, safe and reliable, securing guidance of guided vehicles, ideally, easily adaptable to any type of vehicle guided by rail, regardless of the geometry of the rail.
Un autre but de l'invention est de développer une solution à la détection et au contrôle de la présence d'un rail qui soit efficace en environnement extérieur contraignant.Another object of the invention is to develop a solution for detecting and controlling the presence of a rail that is effective in a constraining external environment.
Par environnement extérieur contraignant, il est fait référence à l' empoussièrement , à l'encrassement, aux vibrations et aux variations climatiques, tel que par exemple les variations de températures (-330C à 500C) ou d'humidité, la forma- tion de glace, etc. Ladite méthode et ledit dispositif seront alors qualifiés de sûr s'ils permettent de détecter avec certitude un déraillement ou un mauvais enraillement, et de fiable s'ils permettent d'éviter des fausses détections, i.e. une détection d'un déraillement, alors que l' enraillement est correct.By constraining external environment, reference is made to dusting, fouling, vibrations and climatic variations, such as, for example, temperature variations (-33 ° C. to 50 ° C.) or humidity. ice formation, etc. Said method and said device will then be qualified as safe if they make it possible to detect with certainty a derailment or a bad wreck, and reliably if they make it possible to avoid false detections, ie a detection of a derailment, whereas the 'srail is correct.
Dans ce but, un dispositif et une méthode sont proposés par le contenu des revendications 1 et 6. A partir d'une méthode de contrôle de présence d'au moins un rail de guidage d'un véhicule guidé, liée en particulier à une sécurisation d'un enraillement dudit véhicule guidé, et comprenant : - une première détection de la présence dudit rail au moyen d'un premier détecteur situé en aval d'une roue, ladite roue pouvant en particulier être un galet,For this purpose, a device and a method are proposed by the content of claims 1 and 6. From a method for checking the presence of at least one guide rail of a guided vehicle, linked in particular to securing a braking of said guided vehicle, and comprising: a first detection of the presence of said rail by means of a first detector located downstream of a wheel, said wheel being able in particular to be a roller,
- une transmission, par ledit premier détecteur, à un organe de contrôle, d'un premier signal relatif à ladite présence dudit rail, la méthode selon l'invention est caractérisée para transmission, by said first detector, to a control member, of a first signal relating to said presence of said rail, the method according to the invention is characterized by
- un branchement en parallèle avec ledit premier détecteur d'au moins un second détecteur situé en amont de ladite roue, ou en particulier dudit galet, - une seconde détection de la présence dudit rail au moyen dudit second détecteur,a connection in parallel with said first detector of at least one second detector located upstream of said wheel, or in particular of said roller, a second detection of the presence of said rail by means of said second detector,
- une communication audit organe de contrôle par ledit second détecteur d'un second signal relatif à ladite présence dudit rail.a communication to said control member by said second detector of a second signal relating to said presence of said rail.
Afin d'éviter toute ambiguïté, par définition, "amont" et "aval" font respectivement référence à la direction d'où vient un déplacement et à la direction où va un déplacement dans un référentiel lié au rail. Une position avale d'un dé- tecteur signifie que ledit détecteur précède ladite roue lors de son déplacement, et une position amont signifie que ledit détecteur suit ladite roue, i.e. se situe après ladite roue par rapport à son déplacement. Ainsi, un détecteur amont et un détecteur aval encadrent de part et d'autre une roue, sui- vant un axe longitudinal du rail.In order to avoid any ambiguity, by definition, "upstream" and "downstream" respectively refer to the direction from which a displacement comes and to the direction in which a displacement in a reference linked to the rail is going. A downstream position of a detector means that said detector precedes said wheel as it moves, and an upstream position means that said sensor follows said wheel, i.e. is located after said wheel with respect to its movement. Thus, an upstream detector and a downstream detector frame on either side a wheel, following a longitudinal axis of the rail.
De plus, la méthode de contrôle selon l'invention est caractérisée par une réalisation en temps réel libre de contact avec ledit rail de ladite détection, que ce soit ladite pre- mière ou ladite seconde détection. En particulier, non seule- ment la détection, mais aussi un signalement de la présence ou absence de rail par lesdits détecteurs à l'organe de contrôle est réalisé en temps réel, de sorte que l'organe de contrôle surveille et connaisse en temps réel l'état de l'en- raillement. Avantageusement, une surveillance en temps réel de 1 ' enraillement d'une roue sur son rail améliore la sécurisation du guidage d'un véhicule guidé.In addition, the control method according to the invention is characterized by a free real-time realization of contact with said rail of said detection, whether it is said first or second detection. In particular, not only detection, but also a signaling of the presence or absence of rail by said detectors to the control member is realized in real time, so that the control organ monitors and knows in real time the state of the intrusion. Advantageously, a real-time monitoring of the braking of a wheel on its rail improves the securing of the guidance of a guided vehicle.
De plus, la méthode de contrôle selon l'invention est en par- ticulier caractérisée par un montage du premier détecteur sur un premier support en aval de la roue et du second détecteur sur un second support en amont de ladite roue, lesdits supports étant fixés par exemple à un bras portant ladite roue, ou en particulier, un bras porte-galets.In addition, the control method according to the invention is particularly characterized by mounting the first detector on a first support downstream of the wheel and the second detector on a second support upstream of said wheel, said supports being fixed. for example to an arm carrying said wheel, or in particular, a roller holder arm.
D'autre part, la méthode de contrôle selon l'invention est en particulier caractérisée par une indication ou une validation par l'organe de contrôle d'un état de rail présent, i.e. d'un état d ' enraillement correct, si au moins un parmi lesdits premier et second signaux signale la présence du rail. En particulier, l'organe de contrôle contrôle 1 ' enraillement d'au moins une roue positionnée à au moins une des extrémités du véhicule guidé. Tant qu'au moins un des signaux parmi les deux signaux provenant respectivement des deux détecteurs as- sociés à une même roue signale la présence du rail, l'état d ' enraillement est considéré comme correct par l'organe de contrôle et il est alors apte à valider l'état de rail présent. Par contre, dès que deux signaux provenant respectivement des deux détecteurs associés à une même roue indiquent une absence de rail, l'organe de contrôle est apte à signaler un déraillement. En particulier, les conséquences du signalement du déraillement par l'organe de contrôle sont par exemple un freinage d'urgence du véhicule guidé conduisant à un arrêt d'urgence dudit véhicule, l'envoi, par exemple par l'organe de contrôle, d'un signal d'alerte ou d'une alarme à un poste de commande, et une inspection sur le lieu du freinage d'urgence des causes et conséquences dudit freinage par le personnel d'exploitation.On the other hand, the control method according to the invention is in particular characterized by an indication or a validation by the control member of a present rail state, ie a correct braking state, if at least one of said first and second signals signals the presence of the rail. In particular, the control member controls 1 'braking of at least one wheel positioned at at least one end of the guided vehicle. As long as at least one of the two signals coming respectively from the two detectors associated with the same wheel signals the presence of the rail, the state of braking is considered correct by the control member and it is then able to validate the state of rail present. On the other hand, as soon as two signals coming respectively from the two detectors associated with the same wheel indicate a lack of rail, the control unit is able to signal a derailment. In particular, the consequences of the report of the derailment by the control member are for example an emergency braking of the guided vehicle leading to an emergency stop of said vehicle, the sending, for example by the control body, d an alert signal or an alarm at a control station, and an inspection at the place of emergency braking of the causes and consequences of said braking by the operating personnel.
Egalement, chacune desdites détections, i.e. la première et la seconde détection, est basée sur une utilisation d'au moins un opérateur logique lors d'un contrôle de la présence dudit rail par ledit organe de contrôle. Par exemple, lesdits détecteurs, situés de part et d'autre d'une même roue, sont branchés en parallèle afin de réaliser un "OU" logique qui permet à l'organe de contrôle de considérer un état d'enrail- lement correct si l'un ou l'autre des détecteurs détecte une présence du rail et la signale à l'organe de contrôle. Avantageusement, le branchement en parallèle des détecteurs selon un "OU" logique permet de s'affranchir de nombreux problèmes, comme par exemple:Also, each of said detections, i.e. the first and the second detection, is based on a use of at least one logical operator when checking the presence of said rail by said controller. For example, said detectors, located on either side of the same wheel, are connected in parallel in order to produce a logical "OR" which allows the control element to consider a correct stall condition if one or other of the detectors detects a presence of the rail and signals it to the control organ. Advantageously, the parallel connection of the detectors according to a logical "OR" makes it possible to overcome many problems, for example:
- les lacunes de rail de toutes natures, tel les joints éclissés, les joints de dilatation, les joints isolants, les lacunes en aiguillage: dans ce cas, lorsqu'un des détecteurs signale une absence de rail, l'autre détecteur, ne se trouvant pas encore au niveau de ladite lacune, signale une présence dudit rail, ce qui permet à l'organe de contrôle de valider un enraillement correct,- Rail gaps of all kinds, such as joints spliced, expansion joints, insulating joints, gaps in switching: in this case, when one of the detectors indicates a lack of rail, the other detector, does not not yet at the level of said gap, signals a presence of said rail, which allows the control body to validate a correct gear,
- les effets de l'attitude du véhicule guidé vis-à-vis du rail tel une variation d'assiette d'un bras portant ladite roue (par exemple un bras porte-galet ou une boîte d'essieu), ainsi que les effets conjugués du profil de la voie et/ou de la dynamique du véhicule: dans ce cas, 1 ' éloignement d'un détecteur par rapport au rail, éloignement qui pourrait poten- tiellement causer une alarme ou un freinage d'urgence, est compensé par un rapprochement corrélatif de l'autre détecteur, de sorte qu'il y ait toujours au moins un desdits détecteurs qui détecte une présence du rail,the effects of the attitude of the guided vehicle with respect to the rail, such as a variation in the attitude of an arm carrying said wheel (for example a wheel-carrier arm or an axle-box), as well as the effects In this case, the distance of a detector from the rail, distance which could potentially cause an alarm or emergency braking, is compensated for by the combination of the track profile and / or the vehicle dynamics. a correlative approximation of the other detector, so that there is always at least one of said detectors which detects a presence of the rail,
- une panne d'un détecteur: en cas de panne d'un des détec- teurs, l'autre détecteur est toujours apte à signaler la pré- sence du rail, et de plus, l'organe de contrôle est apte à signaler un disfonctionnement du détecteur signalant une absence de rail continue.- failure of a detector: in case of failure of one of the detectors, the other detector is always able to signal the pre- sence of the rail, and moreover, the control member is able to signal a malfunction of the detector signaling a lack of continuous rail.
De plus, le branchement en parallèle desdits détecteurs permet ainsi de nombreuses améliorations. Il s'agit par exemple de filtrer des fausses alarmes sur un desdits détecteurs, d'améliorer une tolérance à des variations d'assiettes d'un bras porte-galets sur lequel sont montés lesdits détecteurs ou encore d'améliorer la fiabilité de la détection de présence de rail lors de la présence de joints de rail en matériau isolant non-métallique.In addition, the parallel connection of said detectors and allows many improvements. It is for example to filter false alarms on one of said detectors, to improve a tolerance to variations of plates of a roller arm on which said detectors are mounted or to improve the reliability of the detection. presence of rail when rail joints of non-metallic insulating material are present.
D'autre part, la méthode de contrôle selon l'invention est en particulier caractérisée en ce que au moins une desdites détections est effectuée au moyen d'un détecteur de proximité afin d'être une détection de proximité. Avantageusement, et de façon non exhaustive, ladite détection de proximité est basée sur un effet capacitif ou inductif, ou une combinaison d'un effet capacitif et d'un effet inductif, afin de détecter, par exemple une proximité métallique correspondant à la présence du rail. Avantageusement, ladite détection de proximité, libre de contact avec le rail et basée notamment sur un effet capacitif et/ou inductif afin de détecter le rail, per- met non seulement d'éviter les problèmes liés à l'empoussiè- rement, mais aussi un contrôle de la présence du rail dans des environnements particulièrement contraignants pour un fonctionnement dudit véhicule guidé et de l'ensemble de ses composantes .On the other hand, the control method according to the invention is characterized in that at least one of said detections is performed by means of a proximity detector in order to be a proximity detection. Advantageously, and not exhaustively, said proximity detection is based on a capacitive or inductive effect, or a combination of a capacitive effect and an inductive effect, in order to detect, for example, a metallic proximity corresponding to the presence of the rail. Advantageously, said proximity detection, free of contact with the rail and based in particular on a capacitive and / or inductive effect in order to detect the rail, makes it possible not only to avoid problems related to dusting, but also a control of the presence of the rail in particularly constraining environments for operation of said guided vehicle and all its components.
Finalement, un câblage en série d'une information logique de présence ou absence de rail, provenant soit de l'organe de contrôle, soit directement desdits détecteurs, avec un dispositif de détection d'obstacles, généralement également pré- sent aux extrémités du véhicule guidé, permet en particulier de combiner la détection d'obstacles au dispositif de contrôle de la présence du rail.Finally, serial wiring of a logic information of presence or absence of rail, either from the control member, or directly from said detectors, with an obstacle detection device, generally also present at the ends of the vehicle. guided, allows in particular to combine the detection of obstacles with the device for checking the presence of the rail.
A partir d'un dispositif de contrôle de présence d'au moins un rail de guidage d'un véhicule guidé, lié à une sécurisation d'un enraillement de véhicules guidés et comprenant:From a device for checking the presence of at least one guide rail of a guided vehicle, linked to a securing of a guided vehicle and comprising:
- un premier détecteur situé en aval d'une roue, ladite roue étant en particulier un galet, et, ledit détecteur étant apte à détecter la présence dudit rail et à transmettre un premier signal relatif à ladite présence dudit rail à un organe de contrôle, le dispositif selon l'invention est caractérisé en ce quea first detector located downstream of a wheel, said wheel being in particular a roller, and said detector being able to detect the presence of said rail and to transmit a first signal relating to said presence of said rail to a control member, the device according to the invention is characterized in that
- un second détecteur situé en amont de ladite roue, ou en particulier dudit galet, est apte à être connecté en parallèle avec ledit premier détecteur et à détecter ladite présence dudit rail (1),a second detector situated upstream of said wheel, or in particular of said wheel, is able to be connected in parallel with said first detector and to detect said presence of said rail (1),
- ledit second détecteur est apte à communiquer audit organe de contrôle un second signal relatif à ladite pré- sence dudit rail.said second detector is able to communicate to said control member a second signal relating to said presence of said rail.
En particulier, le dispositif selon l'invention est caractérisé en ce que lesdits détecteurs sont aptes à effectuer une détection en temps réel et libre de contact avec ledit rail. En particulier, les détecteurs sont non seulement aptes à détecter en temps réel la présence dudit rail, mais aussi à signaler en temps réel à l'organe de contrôle la présence ou absence dudit rail, de sorte que l'organe de contrôle est apte à surveiller et à connaître en temps réel l'état correct de 1 ' enraillement, i.e. la présence ou absence de rail.In particular, the device according to the invention is characterized in that said detectors are capable of real-time detection and free of contact with said rail. In particular, the detectors are not only able to detect in real time the presence of said rail, but also to report in real time to the control member the presence or absence of said rail, so that the control member is able to monitor and know in real time the correct state of the train, ie the presence or absence of rail.
En outre, le dispositif selon l'invention est caractérisé en ce que le dit organe de contrôle est apte à valider un état d' enraillement correct, i.e. valider un état de rail présent, en utilisant au moins une opération logique. En particulier, l'organe de contrôle est apte à confirmer/valider la présence du rail en utilisant un "OU" logique, i.e. si au moins un parmi lesdits premier et second signaux détecte et signale la présence du rail. Avantageusement, un fonctionnement de la surveillance de la présence dudit rail au moyen d'un opérateur logique tel la fonction "OU" logique permet de filtrer de fausses alarmes sur un desdits détecteurs, mais aussi, améliore une tolérance de la détection à des variations d'assiette d'un bras porte-galets par rapport au rail, de sorte que lorsqu'un des capteurs s'éloigne du rail et signale une absence de rail, l'autre s'en rapproche corrélativement et signale une présence de rail. Du fait que dans ce cas, un des détecteurs signale une présence de rail, l'opération logique "OU" permet à l'organe de contrôle de conclure à la présence dudit rail, et ainsi de confirmer ou valider un état d'en- raillement correct. De même, l'utilisation d'un opérateur logique tel le "OU" améliore la tolérance de la détection aux joints de rails, en particulier en matériaux isolants non métalliques. En effet, étant donné que lors du passage de la roue sur un joint non-métallique, le premier détecteur, passant au-dessus dudit joint non métallique, indiquera une absence de rail, alors que, au même instant, le second détecteur, suffisamment distant du premier détecteur pour être en regard du rail et non du joint, signalera la présence du rail. Ainsi, comme au moins le second détecteur indique une présence de rail, l'organe de contrôle conclura à un enrail- lement correct et n'alertera par exemple aucun poste de contrôle .In addition, the device according to the invention is characterized in that said control member is able to validate a correct braking condition, ie to validate a rail state present, using at least one logical operation. In particular, the control member is able to confirm / validate the presence of the rail using a logical "OR", ie if at least one of said first and second signals detects and signals the presence of the rail. Advantageously, an operation of monitoring the presence of said rail by means of a logic operator such as the logical "OR" function makes it possible to filter false alarms on one of said detectors, but also, improves a tolerance of the detection to variations of the plate of a roller arm relative to the rail, so that when one of the sensors away from the rail and reports a lack of rail, the other is correlatively closer and signals a presence of rail. Since in this case, one of the detectors indicates a presence of rail, the logical operation "OR" allows the control body to conclude the presence of said rail, and thus to confirm or validate a state of mockingly correct. Likewise, the use of a logical operator such as "OR" improves the tolerance of detection at rail joints, in particular of non-metallic insulating materials. Indeed, since during the passage of the wheel on a non-metallic seal, the first detector passing above said non-metallic seal, will indicate a lack of rail, while at the same time, the second detector, sufficiently remote from the first detector to be opposite the rail and not the seal, will signal the presence of the rail. Thus, since at least the second detector indicates a presence of rail, the control member will conclude with a correct stall and will not, for example, alert any control station.
En particulier, le dispositif selon l'invention est caractérisé en ce que au moins un desdits détecteurs est un détecteur de proximité, comme par exemple un détecteur de proximité métallique. En particulier, le dispositif selon l'invention est caractérisé en ce que lesdits détecteurs dé- tectent la présence du rail au moyen d'une détection de proximité capacitive ou par induction. De manière générale, la détection de proximité n'est pas limitée à une détection basée sur un effet capacitif ou inductif, mais peut aussi, par exemple, être basée sur une combinaison de ces effets. Avantageusement, une détection libre de contact avec le rail, notamment au moyen de détecteurs capacitifs ou inductifs, permet d'éviter les problèmes liés à 1 ' empoussièrement . De plus, les détecteurs de proximités sont aptes à fonctionner dans des environnements particulièrement contraignants.In particular, the device according to the invention is characterized in that at least one of said detectors is a proximity detector, such as for example a metal proximity detector. In particular, the device according to the invention is characterized in that said detectors detect the presence of the rail by means of a detection of capacitive or induction proximity. In general, the proximity detection is not limited to a detection based on a capacitive or inductive effect, but can also, for example, be based on a combination of these effects. Advantageously, free detection of contact with the rail, in particular by means of capacitive or inductive detectors, makes it possible to avoid problems related to dust accumulation. In addition, the proximity sensors are able to operate in particularly demanding environments.
De plus, le dispositif selon l'invention est en particulier caractérisé par un premier et un second support de détecteurs fixés à un bras portant ladite roue respectivement en amont et en aval de ladite roue et auxquels sont fixés respective- ment le premier et second détecteur. En particulier, ledit bras est un bras porte-galets. Avantageusement, le positionnement des détecteurs en amont et en aval de ladite roue, au- dessus ou en particulier au voisinage dudit rail, permet, lors dudit branchement en parallèle desdits détecteurs, d'améliorer la fiabilité de la détection de présence de rail.In addition, the device according to the invention is characterized in particular by a first and a second detector support attached to an arm carrying said wheel respectively upstream and downstream of said wheel and to which the first and second detectors are respectively fixed. . In particular, said arm is a roller holder arm. Advantageously, the positioning of the detectors upstream and downstream of said wheel, above or in particular in the vicinity of said rail, makes it possible, during said parallel connection of said detectors, to improve the reliability of the detection of rail presence.
Finalement, un exemple de réalisation et d'application est fourni à l'aide de:Finally, an exemplary embodiment and application is provided using:
Figure 1 exemple de réalisation de dispositif de contrôle de présence de rail.Figure 1 embodiment of a rail presence control device.
A titre d'exemple, la figure 1 montre un dispositif de contrôle de présence d'au moins un rail (1) de guidage d'un véhicule guidé, lié à une sécurisation d'un enraillement dudit véhicule guidé, comportant:By way of example, FIG. 1 shows a device for checking the presence of at least one rail (1) for guiding a guided vehicle, linked to securing a braking of said guided vehicle, comprising:
- un premier détecteur (41) situé en aval d'une roue ou en particulier d'un galet (3), i.e. précédant la roue ou le galet dans une direction de déplacement de ladite roue ou dudit galet, ledit détecteur (41) étant apte à détecter la présence dudit rail (1) et à transmettre un premier signal (SA) relatif à ladite présence dudit rail à un organe de contrôle (5) , caractérisé en ce quea first detector (41) situated downstream of a wheel or in particular of a roller (3), ie preceding the wheel or the roller in a direction of displacement of said wheel or said roller, said detector (41) being able to detect the presence of said rail (1) and to transmit a first signal (S A ) relating to said presence of said rail to a control member (5), characterized in that
- un second détecteur (42) situé en amont de ladite roue ou dudit galet (3), i.e. suivant ledit galet ou ladite roue dans la direction de déplacement de ladite roue ou galet, est apte à être connecté en parallèle avec ledit premier détecteur (41) et à détecter la présence dudit rail (1),a second detector (42) located upstream of said wheel or said roller (3), ie following said roller or said wheel in the direction of displacement of said wheel or roller, is able to be connected in parallel with said first detector ( 41) and detecting the presence of said rail (1),
- ledit second détecteur (42) est apte à communiquer audit organe de contrôle (5) un second signal (SB) relatif à ladite présence dudit rail (1) .said second detector (42) is able to communicate to said control member (5) a second signal (S B ) relative to said presence of said rail (1).
En particulier, pour chaque roue dont on veut surveiller 1 ' enraillement , un système de détection comprenant au moins deux détecteurs (41, 42) de proximité métallique reliés à au moins un organe de contrôle (5) auquel ils transmettent des signaux (SA, SB) relatifs à la présence dudit rail peut être mis en place. En particulier, lesdits deux détecteurs sont identiques et ont les mêmes caractéristiques de détection de rail. Avantageusement, un unique organe de contrôle (5) est apte à surveiller 1 ' enraillement de plusieurs roues, en par- ticulier, des roues situées aux extrémités dudit véhicule guidé, afin de garantir au moins un enraillement correct des extrémités d'un véhicule guidé. Dans ce cas, les détecteurs associés à plusieurs roues transmettent chacun, au même organe de contrôle, un signal relatif à la présence dudit rail. L'organe de contrôle est ensuite apte à traiter les informations relatives à la présence dudit rail, lesdites informations étant véhiculées à partir desdits signaux transmis par chacun desdits détecteurs. Les détecteurs (41, 42) peuvent avantageusement être fixés sur une boite d'essieu ou sur un organe équivalent solidaire à une cage extérieure des roulements de la roue, tel par exemple un bras porte-galet (2), au plus près de la zone de contact entre la roue et le rail, afin qu'au moins une partie dudit rail soit incluse dans un cône (411, 421) de détection dudit détecteur (41, 42) . Ledit cône de détection correspond à une zone de l'espace pour laquelle le détecteur est apte à détecter la présence du rail.In particular, for each wheel which one wants to monitor 1 'braking, a detection system comprising at least two detectors (41, 42) of metal proximity connected to at least one control member (5) to which they transmit signals (S A , S B ) relating to the presence of said rail can be put in place. In particular, said two detectors are identical and have the same rail detection characteristics. Advantageously, a single control member (5) is able to monitor the rerouting of several wheels, in particular wheels located at the ends of said guided vehicle, in order to guarantee at least a correct braking of the ends of a guided vehicle. . In this case, the detectors associated with several wheels each transmit, to the same control member, a signal relating to the presence of said rail. The control member is then able to process information relating to the presence of said rail, said information being conveyed from said signals transmitted by each of said detectors. The detectors (41, 42) can advantageously be fixed on an axle box or on an equivalent member secured to an outer cage of the wheel bearings, such as for example a roller arm (2), as close as possible to the contact zone between the wheel and the rail, so that at least a portion of said rail is included in a cone (411, 421) for detecting said detector (41, 42). Said detection cone corresponds to a zone of the space for which the detector is able to detect the presence of the rail.
De plus, et en particulier, les détecteurs branchés en parallèle donnent une information binaire à contact sec, comme par exemple, fermé lorsque le rail est présent en regard du détecteur et ouvert lorsque le rail est absent en regard du dé- tecteur. Egalement, le contact "repos" de chaque détecteur, non utilisé pour la détection de présence de rail, peut être utilisé pour détecter les pannes dormantes du détecteur, sans attendre que la panne se révèle par une alarme. Par contact "repos", il est fait référence à l'état du contact d'un dis- positif électromécanique lorsqu'il n'est pas alimenté, cet état pouvant être suivant les cas, soit ouvert, soit fermé. D'autre part, des détecteurs à apprentissage, comme par exemple un détecteur à mémoire d'environnement métallique, peuvent être utilisés, dans le cas où la proximité permanente avec d'autres pièces métalliques, comme par exemple un men- tonnet de roue, gênerait la détection.In addition, and in particular, the detectors connected in parallel give a binary information with dry contact, such as, for example, closed when the rail is present opposite the detector and open when the rail is absent facing the detector. Also, the "rest" contact of each detector, not used for the detection of rail presence, can be used to detect dormant faults of the detector, without waiting for the failure to be revealed by an alarm. By "rest" contact, reference is made to the state of the contact of an electromechanical device when it is not powered, this state being able to be, depending on the case, either open or closed. On the other hand, learning detectors, such as for example a metal environmental memory detector, can be used, in the case where the permanent proximity with other metal parts, such as for example a wheel cap, interfere with the detection.
D'autre part et de manière avantageuse, l'organe de contrôle est apte à être câblé en série avec un dispositif de détec- tion d'obstacle, généralement présent aux extrémités d'un véhicule guidé, afin de combiner ledit dispositif de contrôle de la présence du rail audit dispositif de détection d'obstacles . En résumé, la méthode et le dispositif selon l'invention présentent plusieurs avantages par rapport aux méthodes et dispositifs existant en ce que:On the other hand and advantageously, the control member is adapted to be wired in series with an obstacle detection device, generally present at the ends of a guided vehicle, in order to combine said control device with the presence of the rail to said obstacle detection device. In summary, the method and the device according to the invention have several advantages over existing methods and devices in that:
- ils assurent une détection de la présence du rail indé- pendamment des lacunes de rail nominales,- they ensure detection of the presence of the rail irrespective of the nominal rail gaps,
- ils assurent une détection de la présence du rail, indépendamment de la géométrie du rail, ils améliorent la détection dudit rail lors de variations d'assiette du bras portant ladite roue par rapport au rail,they ensure a detection of the presence of the rail, independently of the geometry of the rail, they improve the detection of said rail during variations of attitude of the arm carrying said wheel with respect to the rail,
- ils permettent de filtrer de fausses alarmes sur un capteur,- they make it possible to filter false alarms on a sensor,
- ils permettent une détection de la présence du rail dans des conditions environnementales de détection contrai- gnantes, notamment lors d' empoussièrement, de températures extrêmes, de haute humidité, they allow a detection of the presence of the rail in harsh environmental detection conditions, in particular during dusting, extreme temperatures, high humidity,
