Abstract

The method involves detecting a vehicle type and presence of passengers on a loading and unloading platform or in a cabin if the vehicle is the cabin, when the vehicle is in upstream of the platform in moving direction of an aerial carrier-tractor cable. A motor is controlled during vehicle displacement to drive the cable at low and high moving speeds if the vehicle is the cabin and a seat, and in case of presence and absence of the passengers, respectively. The detection and the motor control are carried out during passage of the vehicle along the platform of upstream and downstream stations.

Description

Domaine technique de l'inventionTechnical field of the invention

L'invention est relative à un procédé de gestion d'une installation de transport par câble aérien, l'installation comportant :

  • un câble tracteur-porteur monté en boucle fermée entre au moins deux poulies de renvoi,
  • des véhicules d'un premier type constitué par des cabines et d'un deuxième type constitué pas des sièges, les véhicules étant accrochés au câble par des pinces fixes,
  • au moins deux stations d'embarquement et de débarquement des passagers, chacune comprenant une poulie de renvoi, un quai d'embarquement et de débarquement dans les cabines et une zone d'embarquement ou de débarquement sur les sièges,
  • un moteur piloté par une unité de commande et assurant la rotation d'une poulie de renvoi pour l'entraînement du câble.

  • a tractor-carrier cable mounted in a closed loop between at least two return pulleys,
  • vehicles of a first type consisting of cabins and a second type consisting of seats, the vehicles being hooked to the cable by fixed clamps,
  • at least two passenger loading and unloading stations, each comprising a return pulley, a loading and unloading platform in the cabins and an embarkation or disembarkation area on the seats,
  • a motor driven by a control unit and rotating a return pulley for driving the cable.

État de la techniqueState of the art

La présence combinée de sièges et de cabines sur une même installation est déjà connue. Une telle installation permet de répondre simultanément à la demande de deux types d'usagers. Les skieurs sont destinés à être véhiculés sur les sièges, tandis que les cabines assurent le transport des piétons, des enfants ou autres personnes à mobilité réduite. Parallèlement, la sécurité et le confort sont renforcés pour ces deux types d'usagers, grâce à une bonne adaptation du véhicule en fonction des besoins de chacun.The combined presence of seats and cabins on the same facility is already known. Such an installation makes it possible to respond simultaneously to the two types of users. Skiers are intended to be carried on the seats, while cabins transport pedestrians, children or other persons with reduced mobility. At the same time, safety and comfort are reinforced for these two types of users, thanks to a good adaptation of the vehicle according to the needs of each one.

Dans un premier type d'installation, connu par exemple du brevet européen EP1424257 , les véhicules entrant dans une station d'embarquement/débarquement, qu'ils soient du type siège ou du type cabine, sont freinés le long d'un tronçon de ralentissement grâce à un dispositif ralentisseur, après que les pinces soutenant les véhicules sont débrayées du câble aérien. Les véhicules cheminent ensuite le long d'un tronçon de contour de circulation à vitesse réduite grâce à un dispositif d'entraînement équipé généralement de roues à bandage pneumatique. En sortie du tronçon de contour, les véhicules sont pris en charge dans un tronçon d'accélération par un dispositif lanceur dans le but d'atteindre une vitesse correspondant à la vitesse de défilement du câble. En sortie du tronçon d'accélération, les véhicules sont réaccouplés au câble par embrayage des pinces sur le câble.In a first type of installation, known for example from the European patent EP1424257 , vehicles entering a loading / unloading station, whether of the seat or cabin type, are braked along a slowdown section by means of a retarding device, after the clips supporting the vehicles are disengaged aerial cable. The vehicles then travel along a section of reduced speed traffic contour by means of a drive device generally equipped with pneumatic tires. At the output of the contour section, the vehicles are supported in an acceleration section by a launcher device in order to achieve a speed corresponding to the speed of travel of the cable. At the exit of the acceleration section, the vehicles are reconnected to the cable by clutching the clamps on the cable.

Une station aval est munie d'un quai d'embarquement et de débarquement dans les cabines et d'une zone d'embarquement sur les sièges, répartis le long du circuit de transfert suivant la direction de déplacement des véhicules. La vitesse d'entraînement le long du quai d'embarquement et de débarquement dans les cabines est très faible, de l'ordre de 0,25 m/s, tandis que celle-ci est augmentée le long de la zone d'embarquement sur les sièges jusqu'à atteindre approximativement 1 m/s. La vitesse de défilement du câble aérien est quant à elle de l'ordre de 5 m/s, ce qui garantit un débit très important de l'installation. Une station amont présente une configuration inversée, avec une zone de débarquement des sièges puis un quai d'embarquement et de débarquement dans les cabines, ces deux emplacements étant répartis le long du circuit de transfert suivant la direction de déplacement des véhicules.A downstream station is equipped with a loading and unloading dock in the cabins and a boarding area on the seats, distributed along the transfer circuit according to the direction of movement of the vehicles. The drive speed along the loading and unloading platform in the cabins is very low, of the order of 0.25 m / s, while the latter is increased along the loading zone. seats up to approximately 1 m / s. The speed of travel of the aerial cable is about 5 m / s, which guarantees a very high flow rate of the installation. An upstream station has an inverted configuration, with a landing area for the seats and a loading and unloading platform in the cabins, both of which locations being distributed along the transfer circuit according to the direction of movement of the vehicles.

Une telle installation présente l'inconvénient d'être très complexe, ce qui la rend très onéreuse tant à l'implantation qu'à l'exploitation et à la maintenance. D'autre part, chaque station requiert une surface d'implantation au sol supérieure à celles des télécabines et des télésièges classiques.Such an installation has the disadvantage of being very complex, which makes it very expensive both for implementation and operation and maintenance. On the other hand, each station requires a higher floor area than conventional gondolas and chairlifts.

Dans un deuxième type d'installation, connu par exemple du document FR2525169 , les véhicules (sièges et cabines) sont accrochés à un câble tracteur-porteur par des pinces fixes selon une répartition constante le long du câble. La vitesse normale de défilement du câble en cours d'exploitation, par entraînement par l'une des poulies de renvoi, est sensiblement égale à 1m/s, ce qui correspond à la vitesse adaptée pour l'embarquement ou le débarquement des skieurs sur les sièges. La vitesse de défilement du câble est diminuée lorsque chaque cabine passe en station le long d'un quai d'embarquement et de débarquement.In a second type of installation, known for example from the document FR2525169 , the vehicles (seats and cabins) are hooked to a tractor-carrier cable by fixed clamps in a constant distribution along the cable. The normal running speed of the cable during operation, by driving by one of the return pulleys, is substantially equal to 1 m / s, which corresponds to the speed adapted for the loading or unloading of skiers on the seats. The speed of travel of the cable is reduced when each cabin passes station along a loading and unloading platform.

Une telle installation présente l'avantage d'être moins onéreuse car sa conception est véritablement simplifiée, mais le débit en terme de passagers est bien inférieur et ne correspond pas aux attentes des exploitants et des passagers.Such an installation has the advantage of being less expensive because its design is truly simplified, but the flow in terms of passengers is much lower and does not meet the expectations of operators and passengers.

Objet de l'inventionObject of the invention

L'objet de l'invention consiste à proposer un procédé de gestion d'une installation de conception simple et peu onéreuse de transport par câble aérien comportant des sièges et des cabines, qui permette d'avoir un débit élevé en terme de passagers.The object of the invention is to provide a method of managing a simple and inexpensive air-line transport installation comprising seats and cabins, which allows to have a high flow in terms of passengers.

Le procédé selon l'invention est remarquable en ce qu'au passage de chaque véhicule le long du quai d'embarquement et de débarquement de chaque station :

  • on détecte, lorsque ledit véhicule est en amont du quai dans le sens de défilement du câble, le type de véhicule et la présence de passagers sur le quai ou dans la cabine si le véhicule est une cabine,
  • on pilote le moteur, pendant le déplacement dudit véhicule le long du quai, pour entraîner sélectivement le câble à une petite vitesse de défilement si le véhicule est une cabine et si au moins un passager est détecté sur le quai ou dans la cabine, et à une grande vitesse de défilement si le véhicule est un siège ou en cas d'absence de passager.
The method according to the invention is remarkable in that the passage of each vehicle along the loading dock and landing of each station:
  • when the vehicle is upstream of the platform in the running direction of the cable, the type of vehicle and the presence of passengers on the platform or in the cabin are detected if the vehicle is a cabin,
  • the motor is piloted during the movement of said vehicle along the platform to selectively drive the cable at a low speed of travel if the vehicle is a cabin and if at least one passenger is detected on the platform or in the cabin, and a high speed of travel if the vehicle is a seat or if there is no passenger.

Un tel procédé permet d'imposer, pendant le déplacement d'une cabine le long d'un quai d'embarquement et de débarquement, une grande vitesse de défilement du câble en cas d'absence de passagers sur le quai et dans la cabine. La diminution de la vitesse de défilement du câble est commandée en cas de détection sur le quai d'au moins un passager prêt à embarquer ou bien, dans la cabine, d'au moins un passager prêt à débarquer. Ce procédé permet de s'affranchir de ralentissements intempestifs et inutiles de la vitesse de défilement du câble.Such a method makes it possible to impose, during the movement of a cabin along a loading and unloading platform, a high speed of travel of the cable in the absence of passengers on the platform and in the cabin. The reduction in the speed of travel of the cable is controlled in the event of detection on the platform of at least one passenger ready to embark or, in the cabin, of at least one passenger ready to disembark. This method makes it possible to overcome unwanted and unnecessary delays in the speed of travel of the cable.

Selon un mode de réalisation préférentiel, on détecte le type de véhicule avant la fin du déplacement, le long du quai d'embarquement et de débarquement, du véhicule le précédant dans le sens de défilement.According to a preferred embodiment, the type of vehicle is detected before the end of the movement, along the embarkation and unloading platform, of the vehicle preceding it in the direction of travel.

L'invention porte également sur une installation de transport par câble aérien pour la mise en oeuvre du procédé selon l'invention. L'installation est remarquable en ce qu'elle comporte :

  • un premier moyen de détection agencé à un emplacement déterminé le long de la trajectoire des véhicules, en dehors du quai d'embarquement et de débarquement, relié à l'unité de commande pour transmettre un signal de sélection représentatif du type de véhicule lorsqu'un véhicule pénètre dans une zone de détection associée,
  • un deuxième moyen de détection relié à l'unité de commande pour transmettre un signal de présence représentatif de la présence d'au moins un passager sur le quai d'embarquement et de débarquement
  • un troisième moyen de détection transmettant à l'unité de commande un signal de présence associé à chaque cabine et représentatif de la présence d'au moins un passager dans la cabine.
The invention also relates to an installation for transport by aerial cable for implementing the method according to the invention. The installation is remarkable in that it comprises:
  • first detection means arranged at a determined location along the path of the vehicles, outside the loading and unloading platform, connected to the control unit for transmitting a a selection signal representative of the type of vehicle when a vehicle enters an associated detection zone,
  • a second detection means connected to the control unit for transmitting a presence signal representative of the presence of at least one passenger on the loading and unloading platform
  • third detection means transmitting to the control unit a presence signal associated with each cabin and representative of the presence of at least one passenger in the cabin.

Description d'un mode préférentiel de l'inventionDescription of a preferred embodiment of the invention

Sur la figure 1, un câble aérien 10, du type tracteur-porteur, d'une installation de transport s'étend en boucle fermée entre deux stations d'embarquement et de débarquement 11, 12 des passagers P, respectivement aval et amont, en passant dans les stations 11 et 12 sur des poulies de renvoi PM et PF. La poulie de renvoi PM de la station aval 11 est motrice, tandis que la poulie de renvoi PF de la station amont 12 est montée folle. Le câble 10 supporte des véhicules d'un premier type constitué par des cabines C et d'un deuxième type constitué par des sièges S. Les véhicules C et S sont accrochés au câble 10 par des pinces fixes, c'est-à-dire qui n'ont pas vocation à être débrayées du câble 10. L'installation de transport peut comporter d'autres stations intermédiaires prévues le long des voies montante 13 et descendante 14 du câble 10 pour l'embarquement et le débarquement des passagers P dans les véhicules C et S.On the figure 1 an aerial cable 10, of the tractor-carrier type, of a transport installation extends in a closed loop between two loading and unloading stations 11, 12 of the passengers P, respectively downstream and upstream, passing through the stations. 11 and 12 on return pulleys PM and PF. The return pulley PM of the downstream station 11 is driving, while the return pulley PF of the upstream station 12 is mounted idle. The cable 10 supports vehicles of a first type constituted by cabins C and a second type constituted by seats S. The vehicles C and S are hooked to the cable 10 by fixed clamps, that is to say which are not intended to be The transport installation may comprise other intermediate stations provided along the rising and falling channels 14 and 14 of the cable 10 for the loading and unloading of the passengers P in the vehicles C and S.

Outre une poulie de renvoi PM ou PF, chaque station 11 et 12 comporte un quai d'embarquement et de débarquement 15 des passagers P dans les cabines C et une zone d'embarquement 16 ou de débarquement 17 des passagers P sur les sièges S. Dans la station aval 11, les véhicules C et S se déplacent d'abord le long d'un quai d'embarquement et de débarquement 15 prévu sur la première moitié du contour, pour l'embarquement des passagers P de type piétons, enfants ou handicapés. Une zone d'embarquement 16 sur les sièges S est agencée de manière coïncidente avec l'aire balayée par les sièges S sur la deuxième moitié du contour (à la suite du quai 15) pour permettre à des passagers P de type skieurs provenant d'un portillon d'accès 18 à ouverture commandée de venir s'asseoir sur les sièges S suivant la flèche F1.In addition to a return pulley PM or PF, each station 11 and 12 includes a loading dock and landing 15 passengers P in cabins C and a boarding area 16 or landing 17 P passengers on the seats S. In the downstream station 11, the vehicles C and S first move along a loading and unloading platform 15 provided on the first half of the contour, for the boarding of the passengers P type pedestrians, children or disabled. A boarding area 16 on the seats S is arranged coincident with the area swept by the seats S on the second half of the contour (following the platform 15) to allow passengers P type skiers from an access gate 18 with controlled opening to sit on the seats S along the arrow F1.

De manière inversée, les véhicules C et S circulant dans la station amont 12 rencontrent d'abord une zone de débarquement 17 des sièges S puis se déplacent le long d'un quai d'embarquement et de débarquement 15 dans les cabines C. Les passagers P de type skieurs quittent la zone de débarquement 17 en suivant la flèche F2.In an inverted manner, the vehicles C and S traveling in the upstream station 12 first encounter a landing zone 17 of the seats S and then move along a loading and unloading platform 15 in the cabins C. The passengers P type skiers leave the landing area 17 following the arrow F2.

Un moteur M à mode pulsé, logé dans la station aval 11, assure la rotation de la poulie motrice PM pour l'entraînement du câble 10 par l'intermédiaire d'une liaison mécanique 19 pouvant comprendre en série un réducteur et un renvoi d'angle à 90°. Le moteur M est piloté par une unité de commande Uc, par exemple un automate, qui peut assurer d'autres fonctions, en particulier de commande et de surveillance de toute l'installation.A pulsed mode motor M, housed in the downstream station 11, rotates the drive pulley PM for driving the cable 10 by means of a mechanical link 19 which can comprise in series a gearbox and a deflection. 90 ° angle. The motor M is controlled by a control unit Uc, for example a PLC, which can perform other functions, in particular control and monitoring of the entire installation.

L'unité de commande Uc reçoit deux signaux de sélection 201 et 202 provenant d'un premier moyen de détection D11, D12 agencé respectivement à un emplacement déterminé le long de la trajectoire des véhicules sur la voie descendante 14 et à un emplacement déterminé le long de la trajectoire des véhicules sur la voie montante 13. Le moyen de détection D11est agencé en dehors du quai d'embarquement et de débarquement 15 de la station aval 11, en amont de celui-ci dans la direction de défilement du câble 10. Le moyen de détection D11 est relié à l'unité de commande Uc pour transmettre le signal de détection 201 représentatif du type de véhicules C et S qui s'apprête à pénétrer dans la station aval 11. De manière similaire, le moyen de détection D12 est agencé en dehors du quai d'embarquement et de débarquement 15 de la station amont 12, en amont de celui-ci dans la direction de défilement du câble 10. Le moyen de détection D12 est relié à l'unité de commande Uc pour transmettre le signal de détection 202 représentatif du type de véhicule C et S qui s'apprête à pénétrer dans la station amont 12. Le premier moyen de détection D11, D12 est apte à déterminer le type de véhicules C, S, c'est-à-dire à permettre la reconnaissance d'un siège S ou d'une cabine C, et à transmettre un signal de sélection 201, 202 correspondant à l'unité de commande Uc lorsque le véhicule pénètre dans une zone de détection associée. Les moyens de détection D11 et D12 peuvent être constitués par tout moyen approprié.The control unit Uc receives two selection signals 201 and 202 coming from a first detection means D11, D12 arranged respectively at a determined location along the trajectory of the vehicles on the descending path 14 and at a determined location along The detection means D11 is arranged outside the loading and unloading wharf 15 of the downstream station 11, upstream thereof in the direction of travel of the cable 10. detection means D11 is connected to the control unit Uc for transmitting the detection signal 201 representative of the type of vehicle C and S which is about to enter the downstream station 11. Similarly, the detection means D12 is arranged outside the loading and unloading platform 15 of the upstream station 12, upstream thereof in the running direction of the cable 10. The detection means D12 is connected to the co-operating unit. Uc to transmit the detection signal 202 representative of the type of vehicle C and S which is about to enter the upstream station 12. The first detection means D11, D12 is able to determine the type of vehicle C, S, c that is to say to allow the recognition of a seat S or a cabin C, and to transmit a selection signal 201, 202 corresponding to the control unit Uc when the vehicle enters an associated detection zone . The detection means D11 and D12 may be constituted by any appropriate means.

L'unité de commande Uc reçoit aussi deux signaux de présence 211 et 212 provenant d'un deuxième moyen de détection D21, D22 agencé respectivement à proximité du quai 15 de la station aval 11 et à proximité du quai 15 de la station amont 12. Le moyen de détection D21 est relié à l'unité de commande Uc pour transmettre le signal de présence 211 représentatif de la présence d'au moins un passager P situé sur la quai 15 de la station aval 11. De manière similaire, le moyen de détection D22 est relié à l'unité de commande Uc pour transmettre le signal de présence 212 représentatif de la présence d'au moins un passager P situé sur la quai 15 de la station amont 12. Les moyens de détection D21 et D22 peuvent être constitués par tout moyen approprié tel qu'un capteur de présence ou un moyen électrique associé à un portillon d'accès (non représenté) aux quais 15 des stations aval 11 et amont 12.The control unit Uc also receives two presence signals 211 and 212 coming from a second detection means D21, D22 arranged respectively close to the platform 15 of the downstream station 11 and near the platform 15 of the upstream station 12. The detection means D21 is connected to the control unit Uc for transmitting the presence signal 211 representative of the presence of at least one passenger P located on the platform 15 of the downstream station 11. Similarly, the means of detection D22 is connected to the control unit Uc to transmit the presence signal 212 representative of the presence of at least one passenger P located on the platform 15 of the upstream station 12. The detection means D21 and D22 may be constituted by any appropriate means such as a presence sensor or electrical means associated with an access gate (not shown) at the platforms 15 of the downstream stations 11 and upstream 12.

L'unité de commande Uc reçoit aussi, pour chaque cabine C, un signal de présence 23 provenant d'un troisième moyen de détection de présence de passagers P embarqués à bord de la cabine C. L'unité de commande Uc est donc susceptible de recevoir autant de signaux de présence 23 que de cabine C. Un signal de présence 23 est associé à une cabine C et chaque signal de présence 23 est représentatif de la présence ou non d'au moins un passager P embarqué à bord de cette cabine C. Un tel troisième moyen de détection peut être réalisé par tout moyen approprié, fixe dans les stations 11 et 12 de manière à mémoriser les embarquements et débarquements des passagers P pour chaque cabine C, ou bien embarqué dans chacune des cabines C. La transmission des signaux de présence 23 vers l'unité de commande Uc peut se faire par radio ou via des connexions électriques.The control unit Uc also receives, for each cabin C, a presence signal 23 coming from a third means for detecting the presence of passengers P on board the cabin C. The control unit Uc is therefore capable of receive as many presence signals 23 as cabin C. A presence signal 23 is associated with a cabin C and each presence signal 23 is representative of the presence or absence of at least one passenger P on board this cabin C Such third detection means can be achieved by any appropriate means, fixed in the stations 11 and 12 so as to memorize the embarkation and disembarkation of the passengers P for each cabin C, or embarked in each of the cabins C. The transmission of the presence signals 23 to the control unit Uc can be done by radio or via electrical connections.

Au passage de chaque véhicule (cabine C ou siège S) le long du quai d'embarquement et de débarquement 15 de chaque station (amont 12 ou aval 11), l'unité de commande Uc suit l'organigramme représenté sur la figure 2. Le fonctionnement sera expliqué en application au passage d'un véhicule le long du quai 15 de la station aval 11. Dans une première étape F1, le moyen de détection D11 du premier moyen de détection D11, D12 détecte si le véhicule qui s'apprête à longer le quai 15 est un siège S ou une cabine C et transmet à l'unité de commande Uc un signal de sélection 201 représentatif du type de véhicule. Compte tenu de la position du moyen de détection D11, cette détection est réalisée en amont du quai 15 dans le sens de défilement du câble 10 et quelle que soit la vitesse de défilement du câble 10.At the passage of each vehicle (cabin C or seat S) along the loading and unloading platform 15 of each station (upstream 12 or downstream 11), the control unit Uc follows the flowchart shown in FIG. figure 2 . The operation will be explained in application to the passage of a vehicle along the platform 15 of the downstream station 11. In a first step F1, the detection means D11 of the first detection means D11, D12 detects whether the vehicle that is about to along the platform 15 is a seat S or a cabin C and transmits to the control unit Uc a selection signal 201 representative of the vehicle type. Given the position of the detection means D11, this detection is performed upstream of the platform 15 in the direction of travel of the cable 10 and regardless of the speed of travel of the cable 10.

Ensuite, dans une étape suivante F2, le moyen de détection D21 du deuxième moyen de détection D21, D22 réalise la détection de la présence de passagers sur le quai 15 de la station aval 11 et transmet un signal de présence 211 représentatif de la présence d'au moins un passager P sur le quai 15, ou de l'absence de passager P. Ensuite, l'unité de commande Uc détermine dans une étape F3 si le véhicule est une cabine C en fonction du signal de sélection 201 reçu. Si le véhicule est une cabine (sortie Oui de F3), le troisième moyen de détection de présence de passagers à bord de la cabine C transmet un signal de présence 23 représentatif de la présence d'au moins un passager P à bord de la cabine C, ou de l'absence de passager P. Ensuite l'unité de commande Uc détermine dans une étape F5 si au moins un passager P est embarqué dans la cabine C en fonction du signal de présence 23 reçu. Si un passager P est embarqué (sortie Oui de F5), l'unité de commande Uc passe à une étape F6 dans laquelle elle assure le pilotage en vitesse du moteur M, par l'intermédiaire d'un signal de commande 24 adapté, de telle manière que le câble 10 soit entraîné, pendant le déplacement de la cabine C le long du quai 15 de la station aval 11, à une petite vitesse de défilement permettant le débarquement sécurisé du(des) passager(s) embarqué(s) dans la cabine C sur le quai 15. La petite vitesse de défilement est sensiblement égale à 0,25 m/s.Then, in a subsequent step F2, the detection means D21 of the second detection means D21, D22 detects the presence of passengers on the platform 15 of the downstream station 11 and transmits a presence signal 211 representative of the presence of at least one passenger P on the platform 15, or the absence of passenger P. Then, the control unit Uc determines in a step F3 if the vehicle is a cabin C according to the selection signal 201 received. If the vehicle is a cabin (Yes output of F3), the third means of detection of presence of passengers aboard the cabin C transmits a presence signal 23 representative of the presence of at least one passenger P on board the cabin C, or the absence of passenger P. Then the control unit Uc determines in a step F5 if at least one passenger P is embarked in the cabin C according to the presence signal 23 received. If a passenger P is embarked (output Yes of F5), the control unit Uc goes to a step F6 in which it provides the speed control of the motor M, via a control signal 24 adapted, from such that the cable 10 is driven, during the displacement of the cabin C along the platform 15 of the downstream station 11, at a low speed of scrolling allowing the safe landing of the passenger (s) boarded (s) in the cabin C on the platform 15. The low speed of movement is substantially equal to 0.25 m / s.

Par contre, en cas d'absence de passager P dans la cabine C (sortie Non de F5), l'unité de commande Uc détermine dans une étape F7 si au moins un passager P est présent sur le quai 15 de la station aval 11 en fonction du signal de présence 211 reçu à l'étape F2. Si un passager P est présent et prêt pour embarquer (sortie Oui de F7), l'unité de commande Uc passe à l'étape F6 précédemment décrite pour permettre de maintenir la petite vitesse de défilement tant que la cabine C est le long du quai 15 pour que le passager P puisse embarquer dans la cabine C en toute sécurité. Par contre, en cas d'absence de passager P sur le quai 15 (sortie Non de F7), l'unité de commande Uc passe à une étape F8 dans laquelle elle assure le pilotage en vitesse du moteur M, par l'intermédiaire d'un signal de commande 24 adapté, de telle manière que le câble 10 soit entraîné, pendant le déplacement de la cabine C le long du quai 15 de la station aval 11, à une grande vitesse de défilement supérieure à la petite vitesse de défilement.On the other hand, if there is no passenger P in cabin C (exit No of F5), the control unit Uc determines in a step F7 whether at least one passenger P is present on the platform 15 of the downstream station 11 according to the presence signal 211 received in step F2. If a passenger P is present and ready to embark (exit Yes of F7), the control unit Uc goes to the step F6 previously described to maintain the low speed of scrolling as the cabin C is along the dock 15 so that the passenger P can board the cabin C safely. On the other hand, if there is no passenger P on the platform 15 (exit No of F7), the control unit Uc proceeds to a step F8 in which it manages the control. motor speed M, via a control signal 24 adapted, so that the cable 10 is driven, during the movement of the cabin C along the platform 15 of the downstream station 11, at a high speed scrolling higher than the small scrolling speed.

Par conséquent, l'unité de commande Uc impose, pendant le déplacement de la cabine le long du quai 15, une grande vitesse de défilement du câble 10 en cas d'absence de passagers P sur le quai 15 et à bord de la cabine C, et une petite vitesse de défilement du câble 10 si au moins un passager P est détecté sur le quai 15 ou à bord de la cabine C. Ce procédé permet de s'affranchir de ralentissements intempestifs et inutiles de la vitesse de défilement du câble 10, qui se produisaient dans l'art antérieur en cas d'absence de passager P désirant embarquer ou débarquer.Therefore, the control unit Uc imposes, during the displacement of the cabin along the platform 15, a high speed of travel of the cable 10 in the absence of passengers P on the platform 15 and aboard the cabin C and a small speed of travel of the cable 10 if at least one passenger P is detected on the platform 15 or on board the cabin C. This method makes it possible to overcome unwanted and unnecessary delays in the speed of travel of the cable 10 , which occurred in the prior art in case of absence of passenger P wishing to embark or disembark.

A l'étape F3, si le véhicule est un siège S (sortie Non de F3), l'unité de commande Uc passe directement à l'étape F8, de manière à assurer un déplacement rapide du siège S le long du quai 15, pour un gain de temps et donc de rendement en terme de débit de passagers P.In step F3, if the vehicle is a seat S (output No of F3), the control unit Uc goes directly to step F8, so as to ensure rapid movement of the seat S along the platform 15, for a saving of time and therefore of efficiency in terms of passenger flow P.

L'unité de commande Uc assure une gestion identique de la vitesse de défilement du câble 10 pour tout passage d'un véhicule C, S traversant la station amont 12. Cette gestion est réalisée à l'aide du moyen de détection D12, du moyen de détection D22, du troisième moyen de détection, des signaux de sélection 202 et de présence 212 et 23.The control unit Uc provides identical management of the running speed of the cable 10 for any passage of a vehicle C, S through the upstream station 12. This management is performed using the detection means D12, the means detecting means D22, third detection means, selection signals 202 and presence signals 212 and 23.

De manière avantageuse, la grande vitesse de défilement du câble correspond à une vitesse permettant aux passagers P d'embarquer sur les sièges S en toute sécurité au niveau de la zone 16 de la station aval 11, et d'en débarquer en toute sécurité au niveau de la zone 17 de la station amont 12. Un tel choix de grande vitesse de défilement permet d'éviter les variations trop fréquentes de la vitesse de défilement du câble 10, pour augmenter le confort des passagers P embarqués sur les sièges S et dans les cabines C. Autrement dit, le câble 10 est continuellement entraîné soit à la petite vitesse de défilement, soit à la grande vitesse de défilement. La transition éventuelle d'une vitesse de défilement à l'autre vitesse est réalisée pendant qu'un véhicule parcourt le tronçon directement en amont de l'un des quais 15. Si la vitesse de défilement au moment de l'étape F1 est la grande vitesse et si le véhicule est une cabine C, l'unité de commande Uc ne commande la réduction de vitesse de défilement jusqu'à la petite vitesse (selon l'étape F6) pour le déplacement de la cabine C le long du quai 15 en aval que si un passager P est embarqué ou désire embarquer. L'unité de commande Uc assure automatiquement (étape F8) le retour à la grande vitesse de défilement dès la sortie de la cabine C du quai 15 sauf dans le cas où une deuxième cabine C s'apprêterait à son tour à longer l'un des deux quais 15. Dans ce cas, la petite vitesse de défilement est susceptible d'être conservée jusqu'à la fin du déplacement de la deuxième cabine C le long du quai 15 correspondant selon que le cycle appliqué à la deuxième cabine C se termine par l'étape F6 ou l'étape F8. Dans le deuxième cas, la transition de la petite vitesse de défilement jusqu'à la grande vitesse est réalisée dès la fin du déplacement de la première cabine le long du quai 15 correspondant. Elle est également réalisée si les véhicules s'apprêtant à longer les deux quais 15 sont des sièges S. Par conséquent, les étapes F6 et F8 comprennent donc chacune une éventuelle première phase durant laquelle l'unité de commande Uc assure la variation de vitesse de défilement du câble 10 jusqu'à la vitesse de consigne (respectivement la petite et la grande vitesse) et une deuxième phase durant laquelle la valeur de consigne est maintenue. Lorsqu'elle est nécessaire, la première phase est réalisée pendant que le véhicule est directement en amont du quai 15 tandis que la deuxième phase, obligatoire, est réalisée pendant que le véhicule se déplace le long du quai 15.Advantageously, the high speed of travel of the cable corresponds to a speed allowing the passengers P to board the seats S safely in the area 16 of the downstream station 11, and to disembark safely at level of the zone 17 of the upstream station 12. Such a choice of high speed of scrolling makes it possible to avoid the frequent variations of the running speed of the cable 10, for to increase the comfort of the passengers P on the seats S and in the cabins C. In other words, the cable 10 is continuously driven either at the low speed of travel or at the high speed of travel. The transition, if any, from one speed of travel to another speed is carried out while a vehicle travels the section directly upstream of one of the platforms 15. If the speed of scrolling at the time of the step F1 is the great speed and if the vehicle is a cabin C, the control unit Uc does not control the speed reduction to the low speed (according to step F6) for the displacement of the cabin C along the platform 15 in downstream if a passenger P is embarked or wishes to embark. The control unit Uc automatically ensures (step F8) the return to the high speed of movement right out of the cabin C of the platform 15 except in the case where a second cabin C would in turn prepare to go along one 15. In this case, the low speed of scrolling is likely to be maintained until the end of displacement of the second cabin C along the corresponding platform 15 according to the cycle applied to the second cabin C ends by step F6 or step F8. In the second case, the transition from the low speed to the high speed is achieved as soon as the first cabin is moved along the corresponding platform 15. It is also performed if the vehicles preparing to follow the two platforms 15 are S seats. Therefore, the steps F6 and F8 each comprise a possible first phase during which the control unit Uc ensures the variation of speed of running the cable 10 to the set speed (respectively the small and the high speed) and a second phase during which the set value is maintained. When necessary, the first phase is performed while the vehicle is directly upstream of the wharf 15 while the second phase, mandatory, is performed while the vehicle is moving along the wharf 15.

Dans le procédé selon l'invention, au passage de chaque véhicule C, S le long du quai d'embarquement et de débarquement 15 de chaque station 11, 12 :

  • on détecte, lorsque ledit véhicule C, S est en amont du quai 15 dans le sens de défilement du câble 10, le type de véhicule C, S et la présence de passagers P sur le quai 15 ou dans la cabine C si le véhicule C, S est une cabine C,
  • on pilote le moteur M, pendant le déplacement dudit véhicule C, S le long du quai 15, pour entraîner sélectivement le câble 10 à une petite vitesse de défilement si le véhicule C, S est une cabine C et si au moins un passager P est détecté sur le quai 15 ou dans la cabine C, et à une grande vitesse de défilement si le véhicule C, S est un siège S ou en cas d'absence de passager P sur le quai 15 et dans la cabine C.
In the method according to the invention, when each vehicle C, S passes along the loading and unloading platform 15 of each station 11, 12:
  • it is detected, when said vehicle C, S is upstream of the platform 15 in the direction of travel of the cable 10, the vehicle type C, S and the presence of passengers P on the platform 15 or in the cabin C if the vehicle C , S is a cabin C,
  • the motor M is driven during the movement of said vehicle C, S along the platform 15 to selectively drive the cable 10 at a low speed of travel if the vehicle C, S is a cabin C and if at least one passenger P is detected on the platform 15 or in the cabin C, and at a high speed of travel if the vehicle C, S is a seat S or in the absence of passenger P on the platform 15 and in the cabin C.

Dans une variante avantageuse du procédé, chacun des moyens de détection D11 et D12 du premier moyen de détection D11, D12 est disposé de telle manière qu'il est éloigné de la fin du quai 15 directement en aval dans la direction de défilement, d'une distance inférieure à l'espacement entre deux véhicules C, S le long du câble 10. De cette manière, l'étape F1 du cycle à appliquer à un véhicule s'apprêtant à se déplacer le long d'un quai 15 est réalisée avant que l'étape F6 ou F8 du cycle appliqué au véhicule le précédant dans le sens de défilement ne se termine. Ainsi, on détecte le type de véhicule C, S avant la fin du déplacement, le long du quai d'embarquement et de débarquement 15, du véhicule C, S le précédant dans le sens de défilement. Pour y parvenir, la disposition des moyens de détection D11 et D12 dépendent donc de la valeur attribuée à la grande vitesse de défilement et de l'espacement entre les véhicules C, S. Plus précisément, la multiplication de ces deux paramètres doit être inférieure à la distance séparant chaque moyen de détection D11 et D12 et la fin du quai 15 directement en aval dudit moyen.In an advantageous variant of the method, each of the detection means D11 and D12 of the first detection means D11, D12 is arranged such that it is remote from the end of the platform 15 directly downstream in the direction of travel, a distance less than the spacing between two vehicles C, S along the cable 10. In this way, the step F1 of the cycle to be applied to a vehicle preparing to move along a platform 15 is carried out before that step F6 or F8 of the cycle applied to the vehicle preceding it in the direction of travel does not end. Thus, the type of vehicle C, S is detected before the end of the movement, along the loading and unloading platform 15, of the vehicle C, S preceding it in the direction of travel. To achieve this, the arrangement of the detection means D11 and D12 thus depend on the value attributed to the high speed of movement and the spacing between the vehicles C, S. More precisely, the multiplication of these two parameters must be less than the distance separating each detection means D11 and D12 and the end of the platform 15 directly downstream of said means.

Dans une variante préférée, la programmation de l'unité de commande Uc est telle qu'au moins l'étape F2 du cycle à appliquer à un véhicule s'apprêtant à se déplacer le long d'un quai 15 est réalisée à la fin de l'étape F6 ou F8 du cycle appliqué au véhicule le précédant dans le sens de défilement. De ce fait, on détecte la présence de passagers P sur le quai d'embarquement et de débarquement 15 à la fin du déplacement (de préférence juste avant la fin), le long du quai 15, du véhicule le précédant dans le sens de défilement.In a preferred variant, the programming of the control unit Uc is such that at least the step F2 of the cycle to be applied to a vehicle preparing to move along a platform 15 is carried out at the end of step F6 or F8 of the cycle applied to the vehicle preceding it in the direction of travel. As a result, the presence of passengers P on the embarkation and disembarkation wharf 15 is detected at the end of the movement (preferably just before the end), along wharf 15, of the vehicle preceding it in the direction of travel. .

Ainsi, lors du passage d'un véhicule dans une station, si la détection du type de véhicule (étape F1) et la détection de présence de passagers P sur le quai 15 (étape F2) sont toutes deux réalisées avant que l'étape F6 ou F8 du cycle appliqué au véhicule précédent ne se termine, l'unité de commande Uc est en mesure de déterminer si le câble 10 devra être entraîné à la petite vitesse de défilement (étape F6) ou à la grande vitesse de défilement (étape F8) au moment où le véhicule se déplacera le long du quai 15 de ladite station. Une telle gestion offre la possibilité de réaliser les variations de vitesse de défilement de la petite vitesse à la grande vitesse, ou inversement, sur une période de temps suffisante pour qu'elle puisse être pratiquée avec une accélération ou une décélération de faible valeur pour le confort des passagers P embarqués. D'autre part, cette gestion permet d'augmenter la vitesse de défilement (pour un gain en terme de débit de passagers P) jusqu'à la grande vitesse dès la fin du déplacement à petite vitesse d'une cabine C le long du quai 15.Thus, during the passage of a vehicle in a station, if the detection of the vehicle type (step F1) and the detection of presence of passengers P on the platform 15 (step F2) are both carried out before step F6 or F8 of the cycle applied to the preceding vehicle does not end, the control unit Uc is able to determine whether the cable 10 will have to be driven at the low speed (step F6) or at the high speed (step F8 ) when the vehicle will move along the platform 15 of said station. Such management offers the possibility of making variations in speed of movement from low speed to high speed, or conversely, over a period of time sufficient for it to be practiced with a low value acceleration or deceleration for the first time. comfort of passengers P embedded. On the other hand, this management makes it possible to increase the running speed (for a gain in terms of passenger flow P) up to the high speed as soon as the end of the low speed movement of a cabin C along the platform. 15.

Avec une gestion adaptée de la mémoire de l'unité de commande Uc, le premier moyen de détection D11, D12 peut être agencé en un point quelconque de la trajectoire des véhicules C, S sur toute l'installation de transport.With appropriate management of the memory of the control unit Uc, the first detection means D11, D12 can be arranged at any point in the trajectory of the vehicles C, S on the entire transport installation.

Enfin, il est clair que l'étape F2 de détection de présence de passagers P sur le quai 15 peut indifféremment être réalisée entre les étapes F1 et F3 comme précédemment décrit, ou bien entre les étapes F5 et F7. Dans tous les cas, il convient de détecter le type de véhicule C, S et la présence d'au moins un passager P sur le quai 15 ou dans la cabine C si le véhicule C, S est une cabine C, et d'entraîner le câble à la petite vitesse de défilement si le véhicule est une cabine et si au moins un passager P est détecté sur le quai 15 ou dans la cabine C.Finally, it is clear that the passenger presence detection step P 2 P on the platform 15 can indifferently be carried out between the steps F1 and F3 as previously described, or between the steps F5 and F7. In any case, it is necessary to detect the type of vehicle C, S and the presence of at least one passenger P on the platform 15 or in the cabin C if the vehicle C, S is a cabin C, and to train the cable at the low speed of travel if the vehicle is a cabin and if at least one passenger P is detected on the platform 15 or in the cabin C.
