Definitions

  • the present teaching relates to a cableway station for at least one cableway, in which station at least one openable safety barrier is provided, wherein a sensor for detecting an opening state of the at least one safety barrier is provided in the cableway station, said sensor generating a sensor signal as a function of the opening state and sending a sensor signal to a control unit of a cableway drive, wherein the control unit controls the cableway drive as a function of the obtained sensor signal. Furthermore, the present teaching relates to a safety system for a cableway station having an openable safety barrier, and to a method for operating at least one cableway having at least one cableway station, in which an openable safety barrier is arranged.
  • Cableways are used to transport people and materials between two or more cableway stations.
  • a number of cable cars such as chairs or gondolas, are moved between the cableway stations, either circulating or shuttling back and forth.
  • the cable cars are moved between the cableway stations by means of at least one traction cable.
  • the cable car can be suspended from at least one support cable (in the case of an aerial cableway), or can be arranged on rails or on the ground (cable railways) in a manner allowing movement, and can be moved with at least one traction cable.
  • the cable car can also be releasably clamped, or fixed, to the traction cable, and moved with the traction cable.
  • the cable cars are often decoupled from the traction cable in a cableway station, e.g., by means of releasable cable clamps, and are moved through the cableway station at a lower speed, in order to make it easier for people to get on or off, or to make it easier to load or unload material.
  • safety barriers have been used, which trigger an emergency stop of the drive of the cableway upon opening.
  • safety regulations typically state that, during operation of the cableway, there must always be one operator on-site who monitors the operation and controls the cableway.
  • the operating personnel may include one or more persons who are present in order to ensure smooth operation.
  • the operating personnel generally control the cableway from an operation room, which also gives a good visual overview of the areas being monitored, and in particular entry/exit areas and danger areas.
  • the operating personnel generally also assist passengers entering and exiting the cable cars, such as, for example, the chair of a chairlift or the cars of a gondola lift.
  • a safety barrier was triggered, e.g., because a passenger had inadvertently or intentionally entered a restricted area
  • an emergency stop of the cableway was then triggered automatically, and, at the same time, an alarm would also be triggered.
  • the triggering can take place by means of a mechanical contact switch which is actuated when the safety barrier is opened.
  • the contact switch for example, interrupts the energy supply of the cableway drive so that the drive is stopped immediately.
  • the operating personnel already present in the cableway station typically check the area around the safety barrier in order to determine under which circumstances and by whom the safety barrier has been opened. After the check has been completed and it is ensured that there are no more persons in the prohibited area, the operation of the cableway can be continued.
  • the safety barrier would have been manually reset into the closed position by the operating personnel, as a result of which the electrical contact would have been restored by the contact switch.
  • the restart of the cableway is generally also carried out manually—for example, via the controller in the operation room of the cableway station.
  • the control unit is configured to stop the cableway drive, or to reduce a drive speed of the cableway drive, when a sensor signal corresponding to an open position of the safety barrier is received, wherein the safety barrier has a remotely-operable actuating unit which can be controlled by means of a remote control unit in order to reset the safety barrier from the open position, in which the cableway drive is stopped or the drive speed is reduced, into a closed position, in which the cableway drive can be activated again or the drive speed can be increased again.
  • the drive when the safety barrier is actuated, the drive can be stopped completely as usual, or an operation at reduced speed could also take place—for example, if there is no risk of injury upon entering the prohibited area.
  • the cableway drive can be activated again, or the speed can be increased again—for example, from an operation room within the cableway station.
  • control unit is configured to automatically reactivate the cableway drive or to increase the drive speed again when a sensor signal corresponding to the closed position is received, after the remote-controlled reset of the safety barrier from the open position into the closed position by the actuating unit.
  • An alarm unit is preferably also provided in the cableway station and/or outside the cableway station, so that a preferably optical and/or acoustic alarm is triggered, when the open position of the safety barrier is detected by the sensor. As a result, the operating personnel and/or, optionally, other passengers can be alerted.
  • the actuating unit of the safety barrier can be controlled wirelessly and/or by wire via at least one stationary and/or portable remote control unit.
  • at least one stationary and/or portable remote control unit is preferably arranged in the cableway station and/or outside the cableway station.
  • the stationary and/or portable remote control unit is preferably arranged in an operation room within the cableway station and/or in a central operation room for several cableway stations.
  • a mobile telephone or a portable computer can advantageously be provided as a portable remote control unit.
  • the sensor is preferably connected to the control unit in a wireless or wired manner.
  • a very simple system with little installation effort is created by a wireless connection.
  • a camera system with at least one camera and with an evaluation unit is provided as the sensor, wherein at least the safety barrier is arranged in the capture range of the at least one camera, wherein the evaluation unit is configured to evaluate the images captured by the at least one camera in order to detect the opening state of the safety barrier and to transmit the sensor signal to the control unit.
  • the opening state can be detected by means of image recognition, as a result of which no separate sensor has to be arranged directly on the safety barrier.
  • more than one safety barrier can also be monitored with the camera system.
  • At least one camera is provided in the cableway station, wherein the at least one safety barrier is arranged in the capture range of the at least one camera, wherein a display unit for displaying images and/or videos captured by the camera is provided in the cableway station—preferably in an operation room—and/or outside the cableway station—preferably the central operation room for several cableway stations.
  • the operating personnel can visually monitor the area of the safety barrier, e.g., from the operation room, and reset the safety barrier into the closed position with the remote control unit if no potential danger is detected.
  • a mechanical contact switch, inductive sensor, capacitive sensor, light barrier, laser sensor, magnetic sensor, or ultrasonic sensor arranged in the area of the safety barrier can also be provided as the sensor.
  • a suitable switch can be used, depending upon the application; for example, a weather-resistant sensor can be used in an unprotected area.
  • a redundant system could also be provided if, in addition to the camera system, a further sensor is provided, such that the reliability and consequently the safety of the operation of the cableway can be increased. As a result, a relatively simple and robust system can be created.
  • the object is also achieved by a safety system, wherein the safety barrier has a remotely-operable actuating unit in order to reset the safety barrier with a remote control unit from an open position into a closed position.
  • the object is further achieved by a method for operating a cableway, wherein the cableway drive is stopped by the control unit, or a drive speed of the cableway drive is reduced, when the safety barrier is moved from a closed position into an open position, wherein the safety barrier is reset by means of a remote control unit from the open position, in which the cableway drive is stopped or the drive speed is reduced, into the closed position, in which the cableway drive can be activated again or the drive speed can be increased again.
  • FIGS. 1 through 3 show schematic and non-limiting, advantageous embodiments of the present teaching.
  • the drawings show:
  • FIG. 1 a plan view of a cableway station of a cableway
  • FIG. 2 a plan view of a cableway station for three cableways
  • FIG. 3 several, spatially separated cableway stations, each for one cableway, with a central operation room.
  • FIG. 1 is a cableway station 1 of a cableway S designed as a gondola lift.
  • the basic structure and the function of a cableway station 1 are known, which is why a detailed description at this point is dispensed with. The illustration is therefore greatly simplified, and only the components essential for the present teaching are shown.
  • the cableway S has several cable cars F which are moved with a traction cable 12 .
  • the cableway S is designed as a circulating cableway, in which the cable cars F are coupled to and uncoupled from the traction cable 12 .
  • the traction cable is deflected by 180°around a pulley wheel 13 , and is driven by the pulley wheel 13 .
  • a cableway drive 5 e.g., an electrical drive, is provided which drives the pulley wheel 13 .
  • a cableway drive 5 e.g., an electrical drive
  • several cableway stations 1 can also be provided in the cableway, e.g., two end stations and one or more central stations, wherein a cableway drive 5 can be provided in each cableway station.
  • a cable deflection of less than 180° would also be conceivable in principle.
  • at least two cableway stations are usually provided, between which the cable cars F circulate, e.g., to transport persons P and/or objects, wherein a cableway drive 5 is provided in at least one cableway station 1 .
  • a control unit 4 is provided in the cableway station 1 , which control unit is connected to the cableway drive 5 of the cableway S or is integrated therein.
  • the control unit 4 can be used to control the cableway drive 5 in order to control the movement of the pulley wheel 13 and consequently the movement of the traction cable 12 .
  • the speed at which the cable cars F are moved when they are connected to the traction cable 12 can be controlled.
  • the cable cars F of a circulating cableway can also be decoupled from the traction cable 12 upon entry into a cableway station 1 , in order to be able to be moved through the cableway station 1 at a mostly lower speed, independent from the speed of the traction cable 12 .
  • the cable cars F can again be coupled to the traction cable 12 .
  • a more comfortable entry into and exit from the cable cars F within the cableway station 1 can be made possible, and a high conveying capacity can nevertheless be achieved by the unchanged high speed of the traction cable 12 .
  • the cable cars F can be guided, for example, by means of rollers on a guide rail (not shown), which guide rail is arranged in an upper region of the cableway station 1 .
  • the drive of the cable cars F uncoupled from the traction cable 12 during the movement within the cableway station 1 can take place, for example, via a known friction drive.
  • the control unit 4 therefore controls not only the drive of the traction cable 12 , but in particular also the drive of the cable cars F in the uncoupled state, within the cableway station 1 .
  • an operation room 9 is also provided in a cableway station 1 , from which room the responsible operating personnel B control the cableway, and in particular the cableway drive 5 .
  • a control console 14 can be provided in the operation room 9 —for example, in the form of a computer which is connected to the control unit 4 .
  • the operation room 9 is usually arranged in such a manner that the operating personnel B responsible for the operation of the cableway S can view the essential areas, and in particular an entry and/or exit area.
  • the operating personnel B can intervene and stop the cableway drive 5 via the control console 14 , for example, or at least reduce the speed.
  • one or more openable safety barriers 2 can also be provided in the cableway station 1 in order to detect whether a person or an object is positioned in, and/or has entered into, a specific area without authorization.
  • a safety barrier 2 is often arranged in areas which are particularly critical for safety—for example, in the area of the cableway drive 5 of the cableway S in which moving parts are located.
  • a safety barrier 2 is often also arranged in an exit area of the cableway S, in which the cable cars F are again coupled to the traction cable 12 in order to increase the speed again.
  • the safety barrier 2 can be used as a guide contour of the car, for example.
  • the shape of the safety barrier 2 can, for example, be adapted in a substantially complementary manner to the outer contour of the cars, or a part thereof.
  • the cable cars F pass through the safety barrier 2 with the smallest possible distance between the car and the safety barrier 2 transverse to the direction of travel, without the safety barrier 2 being actuated or triggered.
  • certain hazardous situations can occur, e.g., when a car door has not been locked, or has not been locked completely, an object is clamped in the car door, or a person is being dragged along by the cable car, etc.
  • the safety barrier 2 is actuated, because, it is for example actuated or triggered by the laterally protruding (not completely closed) car door, the object, or the person, and is moved from the closed position into an open position during normal operation.
  • Safety barriers 2 can be advantageous in particular in areas which are particularly safety-relevant and/or which are only poorly visible to the operating personnel B.
  • many different elements can be used as safety barriers 2 that are suitable for blocking passage access—for example, doors, bars, etc.
  • the specific embodiment of a safety barrier 2 is irrelevant for the present teaching.
  • three safety barriers 2 are arranged.
  • One safety barrier 2 is arranged in this case in the region of the cableway drive 5 below the pulley wheel 13 in order to block access to the drive, and in particular to the moving parts of the drive.
  • the pulley wheel 13 is shown cutaway in the region of the safety barrier.
  • a further safety barrier 2 is arranged in the exit area of the cableway station 1 , in which the cable cars F are again coupled to the traction cable 12 in order to increase the speed of the cable cars F from the low speed within the cableway station 1 to a relatively higher speed of the traction cable 12 .
  • the safety barrier 2 in the exit area can be provided, for example, as a guide contour for the cable cars F, as was explained above.
  • the third safety barrier 2 is arranged adjacent to the operation room 9 and separates the entry/exit area accessible to passengers from an area to which access is not permitted for persons who are not authorized operators—in particular, passengers.
  • a safety barrier 2 In normal operation of the cableway S, a safety barrier 2 is generally in a closed position in which passage is blocked, and can, for example, be moved from the closed position into an open position when actuated by a person or an object.
  • a sensor 3 with which the opening state of the associated safety barrier 2 can be detected is assigned to each safety barrier 2 .
  • the sensor 3 is connected to the control unit 4 and transmits a sensor signal Y to the control unit 4 as a function of the opening state.
  • the signal transmission can be wired or wireless.
  • the control unit 4 processes the obtained sensor signal Y and controls the cableway drive 5 as a function of the sensor signal Y.
  • a mechanical contact switch, inductive sensor, capacitive sensor, light barrier, laser sensor, magnetic sensor, or ultrasonic sensor arranged in proximity to the safety barrier 2 can be provided as the sensor 3 , as is indicated on the safety barrier 2 in the region of the drive in FIG. 1 .
  • the sensor 3 detects the open position and sends a corresponding sensor signal Y to the control unit 4 .
  • this can mean, for example, that the contact of a contact switch is interrupted.
  • the control unit 4 can trigger an emergency stop of the cableway drive 5 , for example.
  • a safety barrier 2 of an area which is particularly critical with respect to the risk of injury e.g., near the cableway drive 5 in FIG. 1 , or in the exit area of the cable cars F from the cableway station 1 , is actuated. In the case of less-critical areas, however, it is, for example, possible for a reduction in the speed of the cableway drive 5 to simply take place.
  • an emergency stop of the cableway S was generally triggered—for example, because the safety barrier 2 was actuated in the exit area by a passenger who wanted to climb into a cable car F too late.
  • an actuation could also take place by means of an object—for example, an object clamped in the door of a cabin.
  • the responsible operating personnel B previously personally visually checked the area of the safety barrier 2 in question, and identified the cause for triggering the safety barrier 2 . If they determined that a normal operating state existed, or was restored, the safety barrier 2 was manually closed by hand.
  • the cableway drive 5 was then also manually activated by hand by the same person or another person of the responsible operating personnel B—usually from the operation room 9 of the cableway station 1 .
  • a remotely-operable actuating unit 6 is therefore assigned to at least one safety barrier 2 , with which the safety barrier 2 can be moved from the state of the open position back into the state of the closed position by means of a suitable remote control unit 7 , without manual intervention.
  • each of the three illustrated safety barriers 2 is assigned a remotely-operable actuating unit 6 .
  • Remote operation or “from a distance” in this context means in particular that it is possible to take action which affects the safety barrier 2 by means of the actuating unit 6 in order to reset the safety barrier 2 from the open position back into the closed position, without a person of the operating personnel having to be positioned on-site at the safety barrier 2 .
  • the closed position of the safety barrier 2 generally means a position of the safety barrier 2 in the normal state in which an unrestricted normal operation of the cableway S is possible.
  • the open position is generally understood to mean any given position of the safety barrier 2 , deviating from the closed position, by means of which a restricted operation of the cableway S is triggered.
  • the closed position and the open position are detected by means of the at least one sensor 3 .
  • a stationary remote control unit 7 a can be provided as a remote control unit 7 , for example, which is arranged, for example, in the operation room 9 of the cableway station 1 or in a control center that is spatially separated from the cableway, and is operated by a person in the operation room 9 or control center.
  • a central operation room 17 can be provided as a control center, for example, which is provided for controlling several cableways that are spatially separated from one another, as will be explained in detail in FIG. 3 .
  • the stationary remote control unit 7 a can be integrated, for example, in the control console 14 .
  • a mobile remote control unit 7 b could also be provided, by means of which the actuating unit 6 can be controlled locally, independently of the operation room 9 , as is indicated in FIG. 1 at left, above.
  • a suitable mobile telephone such as a smartphone, or a suitable portable computer, such as a tablet computer or the like, can be contemplated.
  • the actuating unit 6 can have, for example, a suitable drive unit, such as an electric drive, via which the safety barrier 2 is reset. Of course, other drives, such as hydraulic, pneumatic, or electromagnetic drives, are also possible.
  • the control of the actuating unit 6 can take place directly, by control signals being transmitted directly from the remote control unit 7 to the actuating unit 6 . This signal transmission can be wireless, e.g., via radio, or conventionally wired—for example, via an electrical line. However, the control can also take place indirectly and centrally via the control unit 4 , by the control signals being transmitted from the remote control unit 7 to the control unit 4 , and the control unit 4 controlling the actuating unit 6 .
  • the closed position is detected by the sensor 3 , and a corresponding sensor signal Y is transmitted to the control unit 4 .
  • the control unit 4 automatically starts the cableway drive 5 when the sensor signal Y corresponding to the closed position is received, or increases the speed of the cableway drive 5 , depending upon whether the drive has been stopped when the safety barrier 2 is opened or only the speed has been reduced.
  • the actuating unit 6 is actuated to close the safety barrier 2 only once the operating personnel B have made certain that there is no longer any risk in the area of the relevant safety barrier 2 .
  • the safety barrier 2 is arranged in the capture range of the camera 10 , and the captured images are transmitted—preferably in the form of a video—to, for example, a suitable display unit, e.g., to a monitor in the operation room 9 , or to the (e.g., stationary or mobile) remote control unit 7 .
  • the operating personnel B can then monitor the situation directly from the operation room 9 or by means of the remote control unit 7 , and can move the safety barrier 2 into the closed position by means of the remote control unit 7 , in order to accordingly restore the operation of the cableway S, and in particular to activate the cableway drive 5 .
  • an advantageous, partially-automated operation of the cableway S can be achieved, and the waiting times before the cableway S is restarted can be shortened, while maintaining the same level of safety.
  • An alarm unit 8 is preferably also provided in the cableway station 1 , which triggers a preferably optical or acoustic alarm signal when the sensor signal Y corresponding to the open position is received.
  • a direct, wireless, or wired transmission of the sensor signal Y to the alarm unit 8 could take place, or the alarm unit 8 can be activated indirectly via the control unit 4 which receives the sensor signal Y.
  • a type of siren could be provided as an alarm unit 8 in order to signal the triggering of a safety barrier 2 .
  • a signal light e.g., a beacon light, could also be provided—for example, additionally or alternatively.
  • one signal light can be arranged per safety barrier 2 , so that the detection of the specific activated safety barrier 2 is facilitated.
  • an alarm unit 8 could also be arranged outside of the cableway station 1 —for example, in a central operation room 17 ( FIG. 3 ).
  • a camera system K which has at least one camera 10 and an evaluation unit 11 , is used as the sensor 3 .
  • the camera 10 is arranged in such a way that at least one safety barrier 2 is arranged in the capture range A of the at least one camera 10 . If it is possible, given the spatial arrangement, several safety barriers 2 can of course also be arranged in the capture range A of a camera 10 , as indicated with dashed lines in FIG. 1 .
  • the evaluation unit 11 is provided to evaluate the images captured by the at least one camera 10 , in order to detect the opening state of the safety barrier(s) 2 and to transmit a sensor signal Y corresponding to the opening state to the control unit 4 .
  • image recognition is implemented in the evaluation unit 11 in a known manner—for example, in the form of hardware and/or software which are designed to detect the opening states of the respective safety barriers 2 .
  • the use of such camera systems K is known in the prior art—for example, by the term, “machine vision.”
  • the evaluation unit 11 can, for example, form one unit with the camera 10 as shown, but could also be integrated, for example, into the control unit 4 , or also be designed as a separate unit.
  • a camera system K conventional sensors in the proximity of safety barriers 2 , for example, can be dispensed with. In order to increase safety, the camera system K and the sensors 3 could also be used in parallel, for reasons of redundancy.
  • FIG. 2 shows a single cableway station 1 for three cableways S 1 -S 3 .
  • Such a configuration can be advantageous, for example, in order to create a common entry point from which passengers can be transported in several different directions. In this case, passengers can decide in the cableway station 1 which cableway S 1 -S 3 to take, and board the corresponding cable car F.
  • a common, instead of three, structurally-separate, cableway stations 1 a more cost-effective and space-saving design can be realized.
  • the cableway drives 5 are controlled by the central control unit 4 , as a result of which, for example, the movement of the cable cars F of the three cableways S 1 -S 3 can be synchronized or coordinated with one another. Due to the separate cableway drives 5 , it is possible that not all the cableways S 1 -S 3 always have to be in operation; rather, for example, only one or two of the three cableways S 1 -S 3 may be in operation. Of course, a shared cableway drive 5 for all the cableways S 1 -S 3 could also be provided.
  • One openable safety barrier 2 which according to the present teaching has an actuating unit 6 which can be controlled by means of a remote control unit 7 , is assigned to each of the exit areas of the cableways S 1 -S 3 .
  • the safety barriers 2 can be provided, for example, as a guide contour for the cabins of the cable cars F, as has been explained earlier.

  • the control console 14 is connected to the central control unit 4 in order to control the cableway drives 5 .
  • Each safety barrier 2 is assigned a camera 10 of a camera system K, which functions as a sensor 3 .
  • Each of the safety barriers 2 is arranged in the capture range A of the associated camera 10 .
  • the evaluation unit 11 of the camera system K is integrated in this case into the control unit 4 .
  • the opening state of the safety barriers 2 is monitored via the camera system K by means of image recognition, and a corresponding sensor signal Y is transmitted to the central control unit 4 when an open position of a safety barrier 2 is detected.
  • the control unit 4 stops the cableway drives 5 of all the cableways S 1 -S 3 as a function of the sensor signal Y, or reduces the speed thereof. In the case of separate cableway drives 5 , it is of course also possible to stop only the specific cableway S 1 , or to reduce the speed thereof, for which the safety barrier 2 has been actuated.
  • one or more alarm units (not shown) is/are preferably provided inside and/or outside the cableway station 1 in order to signal the triggering of the safety barrier 2 .
  • the safety barrier 2 actuated in each case could also be indicated in a suitable manner in the operation room 9 —for example, on a monitor. As a result, a more rapid reaction can take place, because the safety barrier 2 which has been actuated can be identified more quickly.
  • the camera system K in addition to its function as a sensor 3 , is also used to indicate the situation at least in the region of the triggered safety barrier 2 —preferably as a video transmission—to the operating personnel B in the operation room 9 .
  • a potential hazardous situation such as a person who has fallen, or a trapped object, has been rectified, and the relevant safety barrier 2 can be moved back directly from the operation room 9 into the closed position by means of the remote control unit 7 b.
  • the camera system K continues to monitor the safety barrier 2 , and transmits a corresponding sensor signal Y to the control unit 4 when the closed position has been reached.
  • the control unit 4 controls the cableway drives 5 as a function of the obtained sensor signal Y autonomously when the sensor signal Y is received, in order to automatically restore the operation of the given cableway Si or all of the cableways S 1 -S 3 , or to increase the speed thereof again.
  • the operating personnel B can personally evaluate the situation in the region of the safety barrier 2 and restore the operationally-safe state.
  • the safety barrier 2 is able to be closed via a mobile remote control unit 7 b, which is not illustrated in FIG. 2 (see, for example, FIG. 1 ). It can be seen from this that the efficiency of the operation of a cableway compared to conventional cableways can be increased by the present teaching, and at the same time high operational safety can be achieved.
  • the remote operability can also be exploited to actuate several of the safety barriers 2 in cableway stations 1 arranged separately from one another, as explained below with reference to FIG. 3 .

  • Three cableways S 1 -S 3 are provided in the ski area, each with a first cableway station 1 a in the form of a terminal station designed as a lower station, and with a second cableway station 1 b in the form of a terminal station designed as a summit station.
  • further cableway stations 1 in the form of central stations could also be provided in-between.
  • the cableways S 1 -S 3 are embodied as circulating cableways, and each has a plurality of cable cars F which can be moved in a known manner between the cableway station 1 a , 1 b by means of a traction cable 12 in order to transport persons and/or objects from the lower station to the summit station (and vice versa).
  • Several cableway supports 16 are arranged in a known manner between the cableway stations 1 a , 1 b in order to guide the traction cable 12 .
  • the illustration is greatly simplified and shows only the features that are essential for understanding the present teaching.
  • a cableway drive 5 (not shown) is also provided in each case in order to drive the traction cable 12 by means of a pulley wheel 13 , which is indicated by dashed lines.
  • Each of the cableway drives 5 is in turn controlled by a control unit 4 (not shown), as has already been described in detail. Due to simpler installation, the cableway drive 5 is generally provided in the lower station 1 a .
  • the structure and the function of the cableways S 1 -S 3 have already been described with reference to FIGS. 1 and 2 , which is why this is no longer discussed in detail at this point.
  • one or more safety barriers 2 (not shown) is/are provided in the cableway stations 1 a , 1 b of the three cableways S 1 -S 3 , the mode of operation of which has already been described with reference to FIGS. 1 and 2 .
  • the safety barriers 2 each have an actuating unit 6 which can be actuated by means of one (or more) remote control units(s) 7 to enable resetting the safety barriers 2 after the triggering from an open position (in which the cableway drive 5 is interrupted, or at least the speed is reduced) into a closed position (in which the cableway drive 5 can be activated again, or the speed can be increased again).
  • a central operation room 17 is provided alternatively or additionally to operation rooms 9 (see FIGS. 1 and 2 ), which are possibly provided within each of the cableway stations 1 a, 1 b .
  • the central operation room 17 in this case is separated spatially from the cableway stations 1 a , 1 b of the cableway S 1 -S 3 —for example, in a separate building within the ski area.
  • one of the operation rooms 9 of the cableway stations 1 a , 1 b or a central operation room 17 located entirely outside the ski area could also be provided as the central operation room 17 .
  • a stationary remote control unit 7 a is provided, by means of which the actuating units 6 of the safety barriers 2 of all the cableway stations 1 a , 1 b of the cableways S 1 -S 3 can be controlled remotely in order to move the safety barriers 2 from an open position into a closed position.
  • the cableway drive 5 can also be activated again, or the speed can be increased again, after the closed position is reached, from the central operation room 17 —for example, by providing a central control console (not shown) in the central operation room 17 via which the control units 4 can be controlled.
  • the restart of the respective cableway drives 5 is carried out automatically, however, once the closed position of the safety barrier 2 has been detected by the respective sensors 3 , and a corresponding sensor signal Y has been transmitted to the control unit 4 .
  • the cableways S 1 -S 3 can advantageously be controlled centrally, and an at least partially automated operation of the cableways S 1 -S 3 can be achieved, so that no operating personnel B need to be present directly on-site in the cableway stations 1 a , 1 b in order to close the safety barriers 2 .
  • the safety barriers 2 can also be operated by a mobile remote control unit 7 b.
  • closing of the safety barriers 2 and preferably restarting of the respective cableway drives 5 can be carried out, for example, independently of the location of the cableway stations 1 a , 1 b and of the central operation room 17 , as is indicated in FIG. 3 .
  • the communication of the mobile remote control unit 7 b with the control unit 4 of the respective cableways S 1 -S 3 preferably takes place wirelessly—for example, via a suitable radio connection.
  • the area of the safety barrier 2 is monitored by means of a camera 10 (see FIG. 1 ), wherein the captured images or videos are displayed on a display unit—preferably with real-time transmission.
  • the display unit can be provided, for example, within the central operation room 17 —for example, integrated into a central control console in the form of a monitor.
  • a suitable mobile remote control unit 7 b could also serve as a display unit.
  • the situation in the area of the triggered safety barrier 2 can be checked via the display unit in the central operation room 17 (or via the mobile remote control unit 7 b ).
  • the safety barrier 2 Due to the transmitted images or videos of the camera 10 , it can be easily determined whether there is still a potential danger. If necessary, persons of the operating personnel B and/or emergency responders can be sent to the location if, for example, passengers were injured when the safety barrier 2 was triggered. If it is determined on the basis of the transmitted images or videos that there is no longer any danger, the safety barrier 2 can be moved back into the closed position by means of the respective stationary and/or mobile remote control units 7 a, 7 b, and the cableway drive 5 can preferably be restarted automatically.
  • a separate camera 10 is required for the visual monitoring of the safety barrier 2 .
  • a camera system K with at least one camera 10 and with an evaluation unit 11 is provided as the sensor 3 , the camera 10 of the camera system K can advantageously also be used to transmit the captured images and/or videos to the display unit.
  • one or more alarm units 8 can also be provided within and/or outside the cableway stations 1 a , 1 b , in order to trigger an alarm when a safety barrier 2 has been actuated.
  • alarm units 8 could be provided within the cableway station stations 1 a , 1 b in order to signal the triggering of the safety barrier 2 .
  • an alarm unit 8 is also, advantageously, provided in the central operation room 17 in order to signal to the operating personnel B by means of an alarm signal that a safety barrier 2 has been triggered, and preferably also which of the safety barriers 2 has been triggered.
