    The invention relates to a cable car station monitoring device according to the preamble of claim 1 and a method for monitoring a cable car station with a cable car station monitoring device according to claim 9.
    The need to monitor cable car stations due to the increasing urge of the population to experience personal relaxation on a mountain while using a cable car to ascend the mountain is known.
    Typically, the monitoring is carried out by cable car personnel (monitoring person), who observes the entry area and the exit area in a cable car station directly and, if necessary, additionally by means of an electronic aid, such as a camera. The known cable cars have several vehicles, such as cable car cabins or cable car gondolas, which move along a roadway in the cable car station. The users get out of the vehicle in an exit area of the cable car station and leave the cable car station. The vehicle is then moved into an entry area where other users enter the vehicle and are then transported with the vehicle. Since the entry area and the exit area in a cable car station are spatially separated, a single monitoring person cannot be present at the entrance and exit area of the vehicles in the cable car station at the same time and fully recognize and react to all incidents at any time. This one monitoring person usually does not have a complete view of safety-relevant processes in the cable car station. The monitoring persons are partially supported in monitoring, as described above, with electronic aids.
    DE 25 16 777 A1 discloses such an electronic aid, namely a device for monitoring a mountain station of a ski lift with a radiator from which one or more scanning radiators are emitted, which are sent to a receiving device. If a user moves in an area at the exit point or in an area immediately adjacent to it, in which he should not be, in particular for safety reasons, the scanning beams are interrupted by the user who is present. The scanning beam is connected to a control device which brings the ski lift to a standstill when the scanning beam is interrupted by the user present.
    The disadvantage of this known solution is that the ski lift is only stopped when the scanning radiator is interrupted by a user.
    [0006] CH 693 330 A5 discloses a method for automatically monitoring a vehicle of a cable car in the exit area of an arrival area of a cable car station with a laser beam emitted from a laser. The arrival area is divided into monitoring zones and scanned by the laser beam in order to detect the location of an object, such as a backpack, or a user in the monitoring zones. The laser beam can then scan the area. The laser is electrically connected to an evaluation device so that the position signal of the laser beam can be evaluated. The evaluation device then sends out a warning or alarm signal if necessary. The disadvantage of this known solution is that the laser beam only detects a location signal when an object or a user is already in the monitoring zones.
    It is the object of the present invention to eliminate at least one or more disadvantages of the prior art. In particular, a cable car station monitoring device is to be created which further improves the safety for the user in a cable car station, with the entry area and the exit area in the cable car station being monitored. Furthermore, a method for monitoring a cable car station with a cable car station monitoring device is to be created, with which the safety for the user of a cable car station is further improved.
    [0008] This object is achieved by the device and method defined in the independent claims. Advantageous further developments are set out in the figures, the description and in particular in the dependent claims.
    The inventive cable car station monitoring device for a cable car station of a cable car which has at least one vehicle movable along a roadway comprises an evaluation device and at least one first sensor unit connected to the evaluation device, the at least one first sensor unit being set up a monitoring area between the movable vehicle and to monitor the road at least in sections. The at least one first sensor unit is further configured to detect a pivoting movement of the vehicle in the cable car station.
    [0010] The cable car station monitoring device thus monitors the pivoting movement of a vehicle in the cable car station. As previously described in the prior art, this does not detect the presence of a person, such as a user of the cable car, or an object such as a backpack, in the monitoring area, but rather the movement of the vehicle itself. With the aid of the at least one first sensor unit thus reacting to an unusual pivoting movement of the vehicle in the cable car station. This pivoting movement of the vehicle in the monitoring area in the cable car station is triggered by a correspondingly high force exerted on the vehicle by a user or an object. For example, this force is applied to the vehicle in the cable car station due to a fall of a user in the immediate vicinity of the vehicle in the cable car station. The monitoring area essentially comprises the space from the floor of the roadway in the cable car station to essentially the lower edge of the vehicle, for example the roadway cabin, and essentially the area of the roadway between the entrance and the exit of the cable car station.
    [0011] Typically, several vehicles move simultaneously along the roadway in the cable car station. These several movable vehicles are spaced from one another. The plurality of movable vehicles move linearly in the direction from the entrance of the cable car station to the exit area of the cable car station, the speed of the vehicles advantageously being reduced accordingly. After the users have got out of one of the several vehicles, this vehicle moves along a lane to the boarding area in the cable car station. In the entrance area of the cable car station, other users get into the vehicle, which leaves the cable car station in the area of the cable car station exit and - if the speed of the vehicle in the cable car station was reduced - it then picks up a higher speed again.
    [0012] In particular, the at least one first sensor unit is set up to detect penetration of the vehicle into the monitoring area due to a pivoting movement of the vehicle in the cable car station. The vehicle penetrates the monitoring area due to a correspondingly high force being applied to the vehicle. This application of force is caused, for example, when several users press against the vehicle at the same time or when a user is trapped underneath the vehicle.
    Alternatively or in addition, a second sensor unit is arranged in the cable car station, which is set up to detect a pivoting movement of the vehicle perpendicular to a lane direction in the cable car station. This pivoting movement of the vehicle, which can be detected perpendicular to the direction of the road, is triggered by a correspondingly high force exerted on the vehicle by a user or by an object. For example, this force is applied directly to the vehicle in the cable car station due to a fall of a user in the immediate vicinity of the vehicle in the cable car station.
    Preferably, the evaluation device is connected to a control device and the evaluation device is set up to output a control signal to the control device in response to the detected pivoting movement of the vehicle. The evaluation device can receive a sensor signal from the at least one first and / or second sensor unit and converts this sensor signal into a control signal for the control device. For this purpose, the evaluation device advantageously has a processor with a program unit. The evaluation device is electrically connected or optically connected to the control device of the cable car station in order to transmit the control signal to the control device in real time. The connection between the control device and the evaluation device can be established with the aid of an optical or electrical line, or it can also be based on a wireless signal, such as a WLAN connection, a Bluetooth® or a radio connection.
    In particular, the control device is set up to activate a braking device for stopping the vehicle in the cable car station. The braking device in the cable car station can automatically stop the vehicle with the help of the control signal, which shortens the reaction time between the detection of the sensor signal and the switching off of the cable car, whereby no monitoring personnel (operating personnel) are required in the cable car station.
    [0016] The evaluation device is advantageously connected to a cable car station control room so that the sensor signals and / or the control signals can be transmitted to a cable car station control room. The cable car station control room is advantageously connected to an evaluation device of a mountain cable car station and to an evaluation device of a valley cable car station. This means that monitoring personnel stationed in the cable car station control room can monitor both cable car stations at the same time.
    The at least one first sensor unit is preferably set up to detect a pivoting movement of the vehicle along the direction of the roadway. The direction of the lane extends from the entry of the vehicle into the cable car station to the exit of the vehicle from the cable car station. The lane direction can change along the lane in the horizontal plane, for example if the lane in the lane station runs along a lane curve. The lane direction along the lane is defined at each position of the lane in the lane station. The detected pivoting movement can run in the direction of the road and / or against the direction of the road.
    [0018] The second sensor unit preferably enters into an operative connection with a first guide unit for detecting the pivoting movement of the vehicle. The first guide unit is typically arranged in the monitoring area so that the detection of the pivoting movement can be assigned spatially or locally in the cable car.
    [0019] The first guide unit advantageously has a first and a second guide element. The first guide element can be arranged as a guide rail in the entry area or exit area of the cable car station, along the roadway in the direction of the lane and is used for stable guidance of the vehicle in the entry area or exit area of the cable car station. The second guide element has the second sensor unit and can enter into an operative connection with a further guide unit on the vehicle if an undesired pivoting of the vehicle occurs perpendicular to the direction of the road. This can further increase the safety of users in the cable car station.
    The second guide element is advantageously movable, in particular horizontally movable, arranged in the first guide unit. The second guide element can be spaced from the first guide element so that the further guide element or the vehicle can simply be pivoted perpendicular to the direction of the road. In this way, for example, the vehicle can commute freely in order to easily free a user trapped in the monitoring area.
    Alternatively or additionally, the second sensor unit enters into an operative connection with the vehicle for detecting the pivoting movement of the vehicle. An undesired pivoting movement of the vehicle perpendicular to the direction of the road outside the monitoring area can easily be detected.
    [0022] The evaluation device is advantageously designed to detect the pivoting movement of the vehicle along the direction of the road with respect to the position of the vehicle in the cable car station. The trapping of an object or a user between the floor in the cable car station and a vehicle can thus be detected.
    [0023] The evaluation device is advantageously designed to detect the pivoting movement of the vehicle perpendicular to the direction of the lane in relation to the position of the vehicle in the cable car station. The trapping of an object or a user between the floor in the cable car station and a vehicle can thus be detected in an improved manner.
    The first sensor unit preferably comprises at least one optical sensor, the at least one optical sensor coming from the group of distance measuring sensors, speed measuring sensors, or remote measuring sensors for measuring atmospheric parameters. An optical sensor sends out at least one optical signal and enables simple, contactless and quick detection of the pivoting movement of the vehicle in the cable car station.
    [0025] A LIDAR or a RADAR system is advantageously used as at least one first sensor unit. LIDAR systems for measuring the atmosphere send out pulse-like sensor signals and detect the light scattered back from the atmosphere. The distance to the point of scattering is calculated from the light transit time of the signals. RADAR systems emit what is known as a primary signal as a bundled electromagnetic wave, which is received as a secondary signal by echoes reflected from objects. The secondary signal is then evaluated, which is used to locate - determine distance and / or angle - of an object.
    The first sensor unit advantageously comprises a plurality of optical sensors, as a result of which the monitoring area can be monitored over a large area.
    The sensor areas of the multiple optical sensors advantageously overlap, so that increased operational safety can be ensured in the cable car station.
    The multiple optical sensors are advantageously arranged on an inside of the roadway. The multiple optical sensors can each be placed on a holder in such a way that the transmitted sensor signals pass underneath the vehicle floor. In this way, the multiple optical sensors can be placed at those points on the inside of the roadway at which the largest area monitoring of the monitored area below the vehicle is achieved, which ensures a high level of safety. The at least one first sensor unit is advantageously based on a high-resolution time-of-flight method for contactless distance measurement from diffusely reflecting objects and from retroreflective reflectors. This allows users and / or objects to be differentiated from snowflakes, rain and fog, since the evaluation device can be used to create an echo sounder method from the time-of-flight method, which can be used in special weather conditions and difficult environmental conditions.
    [0029] The at least one second sensor unit preferably comprises at least one mechanical sensor from the group of pressure sensors or force sensors. The second sensor unit generates a sensor signal, for example proportional to the force and / or pressure, which is transmitted to the evaluation device. The evaluation device can thus easily and reproducibly generate a control command from the electrical signal received in order to transmit it to the control device.
    The control device is advantageously designed, after receiving an electrical signal from the second sensor unit or the evaluation device, to separate the second guide element from the first guide element in order to enable an increased pendulum movement of the vehicle.
    [0031] A reflector is preferably present which interacts with the first sensor unit. This enables improved detection accuracy. The reflector can be arranged opposite the at least one optical sensor and reflects the optical signal back to the first sensor unit, which advantageously has a detection unit for this purpose.
    [0032] The reflector is advantageously arranged at least on the vehicle that can be moved along the roadway. This means that each vehicle in the cable car station can be monitored individually, since the at least one first sensor unit can interact individually with the reflector of the individual vehicle.
    [0033] The reflector for reflecting a sensor beam is advantageously arranged on the side of the vehicle facing away from the entry area of the cable car station. This shortens the path when the sensor beam is reflected back to a sensor, so that a significantly faster reaction time can be achieved in the cable car station monitoring device.
    In particular, the reflector is arranged on an anti-trap guard on the vehicle that can be moved along the roadway. An anti-trap protection can limit the previously defined monitoring area so that the sensor signal transmitted by the at least one sensor unit does not leave the monitoring area and thus realizes improved detection accuracy.
    At least one further sensor unit is preferably present, which is connected to the evaluation device. Another sensor unit enables improved monitoring in the cable car station, with the same monitoring area being able to be monitored in several spatial directions with the aid of the further sensor unit, for example. The at least one first sensor unit can be arranged at 90 degrees to the further sensor unit, so that a two-dimensional sensor network is created and the same monitoring area below the vehicle can thus be monitored more precisely.
    The further sensor unit is advantageously set up to record an image of the monitoring area below the movable vehicle and is designed to transmit this image to the evaluation device. An image recording includes at least a two-dimensional representation of the monitoring area below the movable vehicle. The further sensor unit can thus monitor a larger area in the monitoring area.
    The further sensor unit is advantageously a stereo camera. A stereo camera enables an image to be recorded which, in addition to the two-dimensional display of the monitoring area below the movable vehicle, also contains depth information, that is to say information in a further spatial direction, in the image recording. This makes it possible for a user or an object to detect touching the vehicle and thus the cable car station monitoring device overall has a shorter reaction time for stopping the vehicle moving in the cable car station.
    Alternatively or in addition, the first sensor unit is a stereo camera. In addition to the advantages mentioned above, a stereo camera can be used to detect a swiveling movement of the vehicle in the cable car station in several dimensions.
    [0039] The at least one further sensor unit is preferably arranged in the monitoring area of the roadway. In this way, the monitored area can be observed absolutely or relatively in a simplified manner.
    A display device is preferably present which is electrically connected to the evaluation device. The display device can receive the aforementioned control signal from the evaluation device and convert it into a warning signal. The warning signal can be an acoustic warning signal which is emitted, for example, by the display device. Alternatively or in addition, the warning signal can be an image or a sequence of several images, which are shown on a display on the display device. In this way, at least one user, but also the monitoring staff, can be informed early on of various malfunctions and, in particular, on an abnormal pivoting movement of the vehicle in the cable car station.
    At least one hydraulic device with a coupling unit for at least occasional coupling with the vehicle is advantageously provided in the entry area or exit area of the cable car station. If a user is trapped between the entry area or exit area and the vehicle, this vehicle can be coupled with the aid of the at least one hydraulic device in order to be able to easily free the trapped user. The vehicles preferably have a coupling section or a coupling unit for coupling to the coupling unit of the hydraulic unit, so that the coupling can be carried out in a reproducible manner. The vehicle can be drawn towards the at least one hydraulic device or, alternatively, can be pushed away from the at least one hydraulic device.
    In particular, the hydraulic device is designed to swivel this vehicle away perpendicular to the direction of the road so that other vehicles in the cable car station do not have to be moved.
    At least the second sensor unit is advantageously arranged on the coupling unit of the hydraulic device, so that the pivoting movement of the vehicle is detected and the vehicle is coupled promptly, and a trapped user can be supplied quickly. Alternatively, the coupling unit of the hydraulic device can be moved or controlled pneumatically or electrically.
    [0044] The method according to the invention for monitoring a cable car station with a cable car station monitoring device, in particular with a cable car station monitoring device as described above, comprises at least the following steps:<tb> <SEP> a) Monitoring a monitoring area below a movable vehicle arranged in the cable car station with at least one first sensor unit and / or with a second sensor unit;<tb> <SEP> b) detecting a pivoting movement of the vehicle in the cable car station with the first sensor unit and / or the second sensor unit;<tb> <SEP> c) transmission of the detected sensor signal from the first sensor unit and / or second sensor unit to an evaluation device;<tb> <SEP> d) Output of a control signal to a control device for activating a braking device for the vehicle in the cable car station.
    This method is used to react to the pivoting movement of the vehicle in the cable car station and not, as previously described in the prior art, the presence of a user or an object, such as a backpack, detected in the surveillance area. As described here, the at least one first sensor unit and / or second sensor unit can be used to react to an unusual pivoting movement of the vehicle in the cable car station. This pivoting movement of the vehicle in the cable car station in the monitoring area is triggered by the application of sufficient force by a user or by an object on the vehicle. For example, this force is applied to the vehicle in the cable car station due to a fall of a user in the immediate vicinity of the vehicle in the cable car station.
    In particular, the intrusion of the vehicle into the monitoring area is detected due to a pivoting movement of the vehicle in the cable car station. Penetration of the vehicle into the monitoring area requires a correspondingly high force to be applied to the vehicle. This application of force can arise, for example, when several users press against the vehicle at the same time, or when a user is trapped underneath the vehicle.
    The pivoting movement of the vehicle in the cable car station is preferably detected using a further sensor unit which records at least one image of the monitored area. An image recording enables the two-dimensional monitoring of the monitoring area, so that more data information can be made available to the operating personnel for deciding the relevance of an incident.
    The further sensor unit is advantageously a stereo camera. It is thus possible, as described above, that a person or an object touching the vehicle is detected and the cable car station monitoring device thus requires a shorter overall response time for stopping the vehicle moving in the cable car station.
    Alternatively or in addition, the at least one first sensor unit is a stereo camera. In addition to the advantages mentioned above, a stereo camera can be used to detect a pivoting movement of the vehicle in the cable car station.

    1 and 2 show a first embodiment according to the invention of a cable car station monitoring device 20 for a cable car station 11 of a cable car. The cable car has a vehicle 13 that can be moved along a roadway 14. The vehicle 13 is coupled to a conveyor element S in the cable car station 11 with the aid of a coupling unit 12 and is moved along the track 14 with the aid of the conveyor element S, such as a conveyor rope or a conveyor rail. In addition, the cable car station 11 has a first guide unit 15, such as a cam guide, which is arranged along the track 14. The first guide unit 15 interacts with a further guide unit 16, such as a cam, which is arranged on the vehicle 13, in order to guide the vehicle 13 along the roadway 14. Typically, several vehicles 13 move in the cable car station 11, with the several movable vehicles 13 being spaced from one another (not shown). The vehicle 13 moves linearly in the direction from the entrance B of the cable car station 11 to an exit area 19 of the cable car station 11, the speed of the vehicle 13 being correspondingly reduced. After the users 18 have got out of the vehicle 13 with the vehicle door 17 open, this vehicle 13 moves along a lane curve to an entry area 19 in the cable car station 11. In the entry area 19 of the cable car station 11, further users 18 get into the vehicle 13, which is in the Connection picks up a higher speed again and leaves the cable car station 11 in the area of exit C of the cable car station 11. The cable car station 11 described here has a stepped shoulder between the entry area 19 or exit area 19 and the roadway 14.
    The cable car station monitoring device 20 comprises an evaluation device 35 and at least one first sensor unit 21 connected to the evaluation device 35 by means of a sensor line 33. The first sensor unit 21 is set up to monitor a monitoring area A between the movable vehicle 13 and the roadway 14 at least in sections. The first sensor unit 21 is set up to detect a pivoting movement of the vehicle 13 in the cable car station 11. The first sensor unit 21 has several sensors 25 which emit a sensor beam 22 into the monitoring area A. If the pivoting movement of the vehicle 13 is so pronounced that the vehicle 13 penetrates the monitoring area A at least in sections and thereby interrupts the sensor beam 22, this is detected by the first sensor unit 21. The sensor signal generated in the process is transmitted to the evaluation device 35 by means of the sensor line 33. The sensors 25 convert the sensor signal into an electrical signal so that this electrical signal can be further processed in the evaluation device 35. The evaluation device 35 creates a control command from the electrical signal received and has a processor and a suitable program for this purpose. The evaluation device 35 is electrically connected to a control device 45 of the cable car by means of a control line 44. It is thus possible to output a control signal to the control device 45 of the cable car in response to the detected pivoting movement of the vehicle 13. The control device 45 is then set up to activate a braking device 49 for stopping the vehicle 13 in the cable car station 11. The braking device 49 is electrically connected to the control device 45. The evaluation device 35 is electrically connected by means of a connecting line 48 to a display device 50, which converts the control signal into an acoustic warning signal and / or into an optical warning signal that is displayed on the display device 50.
    The plurality of sensors 25 are mounted on the roadway 14 and are set up to carry out optical distance and speed measurements, as well as remote measurements of atmospheric parameters. The sensors 25 are placed on a holder 26 in such a way that the transmitted pulses pass underneath the vehicle 13 on which the largest area of the roadway 14 is monitored. Here, the first sensor unit 21 is based on a high-resolution time-of-flight method, for example a LIDAR method, for contactless distance measurement of diffusely reflective objects. A pinch protection 40 is arranged on the vehicle 13 in the area of the vehicle door 17 in order to reduce the gap between the roadway 14 and the entry area 19. This prevents a user 18 from being trapped between the vehicle 13 and the roadway 14. On the vehicle 13, a reflector 41 for reflecting the sensor beam 22 back to the sensor 25 is arranged on the vehicle side of the vehicle 13 facing away from the entry area 19.
    As shown in FIG. 2, the first sensor unit 21 has a plurality of sensors 25. These sensors 25 monitor the monitoring area A between the lane 14 and the vehicle 13. The first sensor unit 21 is set up to use these multiple sensors 25 to detect a pivoting movement 24 of the vehicle 13 along the lane direction R. In addition, the pivoting movement 24 of the vehicle 13 along the lane direction R in relation to the position of the vehicle 13 in the cable car station 11 can be seen. The lane direction R extends from the entrance B of the vehicle 13 into the cable car station 11 to the exit C of the vehicle 13 from the cable car station 11.
    3 shows a further embodiment according to the invention of a cable car station monitoring device 55 in the cable car station 11 of a cable car present here, which has a vehicle 63 that can be moved along the carriageway 14. The cable car station monitoring device 55 has, in addition to the cable car station monitoring device 20 described in FIGS. 1 and 2, a further sensor unit 80 which is connected to an evaluation device 85. The evaluation device 85 is electrically connected to the further sensor unit 80 by means of a sensor line 82. The evaluation device 85 receives sensor data from the further sensor unit 80 and processes them into control signals. The evaluation device 85 is designed essentially like the evaluation device 35 already described in FIG. 1. The further sensor unit 80 is arranged in the monitoring area A between the roadway 14 and below the movable vehicle 63 and is set up to record an image of the monitoring area A below the movable vehicle 63. The further sensor unit 80 is designed to transmit this image recording to the evaluation device 85. An image recording includes at least a two-dimensional representation of the monitoring area A below the movable vehicle 63. The further sensor unit 80 is a stereo camera. A trapping protection 65 is arranged on the vehicle 63 so that a user 18 cannot be trapped between the vehicle 63 and the exit area 19 or entry area 19 when he leaves or enters the vehicle 63 through the vehicle door 67.
    4 shows a further embodiment according to the invention of a cable car station monitoring device 120 in a cable car station 111, which is designed essentially the same as the cable car station 11 described above. The cable car station 111, however, has an entry area or exit area 119 which is arranged essentially on a plane with the underside of a movable vehicle 113 arranged in the cable car station 111. The cable car station monitoring device 120 is arranged below the vehicle 113 in the roadway 114. The cable car station monitoring device 120 shown here has a sensor unit 80 for monitoring a monitoring area A1. The sensor unit 80 is a stereo camera. The stereo camera is electrically connected to an evaluation device 135 by means of a sensor line 82. The evaluation device 135 receives image data from the further sensor unit 80 and processes them, as previously described here, into control signals. The control signals are forwarded to the control device 145 of the cable car with the aid of the control line 144, so that it stops the vehicle 113 in an emergency. The evaluation device 135 is connected by means of a connecting line 116 to a display device 115 for displaying warning signals. A trapping protection 140 is arranged on the vehicle 113, so that a user 18 cannot be trapped between the vehicle 113 and the exit area 119 or entry area 119 when the user leaves the vehicle 113.
    In addition, the evaluation device 135 can have a first sensor unit according to FIG. 1 or FIG. 3 (not shown).
    With the help of one of the cable car station monitoring devices 20 or 55 or 120 described in FIGS. 1 to 4, a method according to the invention for monitoring a cable car station 11 or 111 can be carried out. This method will now be described representatively with the aid of FIGS. 1 and 2 and comprises the following steps:<tb> <SEP> A monitoring area A of the roadway 14 below a movable vehicle 13 arranged in the cable car station 11 is monitored with the first sensor unit 21. Subsequently, an impermissible pivoting movement 24 of the vehicle 13 in the cable car station 11 is detected with the first sensor unit 21 when the vehicle 13 enters the monitoring area A. The detected sensor signal is then transmitted from the first sensor unit 21 to the evaluation device 35. The evaluation device 35 uses a processor and a program stored on it to generate a control signal from the sensor signal. The control signal is output to a control device 45 of the cable car, so that this control device 45 subsequently stops the vehicle 13 moving in the cable car station 11. At the same time, a control signal is transmitted from the display device 35 to a display device 50 so that a warning signal is displayed there.
    5 shows a further embodiment according to the invention of a cable car station monitoring device 220 in a cable car station 211. The cable car has a vehicle 13 that can be moved along the roadway 14, the vehicle 13 and the roadway 14 essentially having the functional and structural features as previously in FIG 1 to 4 described embodiments. In addition, the cable car station 211 has a first guide unit 215 which is designed in two parts. The guide unit 215 consists of a first guide element 215a, which is arranged, for example, as a guide rail in the entry area or exit area 219 along the roadway 14 in the roadway direction 24. The vehicle 13 has the further guidance unit 16, as described above. The further guide unit 16 and the first guide element 215a interact to guide the vehicle 13 along the roadway 14. The guide unit 215 has a second guide element 215b, which is arranged on a second sensor unit 221 in the cable car station 211. The second sensor unit 221 is set up to monitor a monitoring area A between the movable vehicle 13 and the roadway 14, at least in sections. The second guide element 215b is, for example, a mechanical sensor 225, such as a sensor rail or a sensor plate. This detects a force effect and / or a pressure effect, triggered by a force or a pressure of the guide unit 16 on the second guide element 215b. The second guide element 215b is movable and can be distanced from the first guide element 215a. The second guide element 215b generates a sensor signal in the sensor unit 221, for example proportional to the force and / or pressure effect when pivoting perpendicular to the direction of the road, which is transmitted to the evaluation device 235. The evaluation device 235 creates a control command from the electrical signal received and has a processor and a suitable program for this purpose. The evaluation device 235 is electrically connected to a control device 245 of the cable car by means of a control line, as described here. The second sensor unit 221 is thus set up to detect a pivoting movement of the vehicle 13 perpendicular to a lane direction R. The second guide element 215b is arranged on a hydraulic device 285. When a sufficiently high force or a sufficiently high pressure is detected, the second guide element 215b is moved in the direction of the hydraulic device 285, so that the distance between the first guide element 215a and the second guide element 215b is increased. The hydraulic device 285 has a coupling unit 286 for at least temporary coupling to the vehicle 13. The coupling unit 286 connects during coupling to a coupling unit 13a or a coupling section on the vehicle 13 and moves the coupled vehicle 13 perpendicular to the direction of the roadway R. the guide unit 16 is pivoted (pushed or pulled) further out of the lane direction R. In addition, the second sensor unit 221 enters into an operative connection with the vehicle 13 for detecting the pivoting movement of the vehicle 13 and is arranged on the further hydraulic device 295. The control device 245 controls the hydraulic devices 285, 295. Such hydraulic devices 285, 295 can also be arranged in the cable car stations 11 and 111 according to FIGS. 1 to 4.
    6 shows a further embodiment according to the invention of a cable car station monitoring device 320 in a cable car station 311. The cable car has a vehicle 13 which can be moved along the roadway 14, the vehicle 13 and the roadway 14 essentially having the functional and structural features as previously in FIG Fig. 1 to 4 described has. This cable car station monitoring device 320 comprises both the structural and functional features of the cable car station monitoring devices 20 and 120, as well as the cable car station monitoring device 220. Thus, the intrusion of the vehicle into the monitoring area A due to a pivoting movement of the vehicle 13 is not only monitored optically - see details on this in FIG. 1 4 - but also mechanically monitored - see details in FIG. 5. The evaluation device 335 is electrically connected to the sensor units 21, 80, 221 in order to transmit control signals to the control device 345.
