    description
    PRIOR ART When assembling trains which are formed from a plurality of wagons, in particular freight wagons, a method is often used in which individual wagons are placed on the respectively associated track of a train formation system, where they either roll to a standstill come or be slowed down by shunting staff using an inhibitor. As a rule, the wagons are not pushed by shunting locomotives when they are moved, but roll automatically. The wagons receive the required initial impulse either by pushing them with a shunting locomotive or by rolling down a drain mountain. If the initial impulse of the wagons is not sufficient to reach an intended end position on the corresponding track of the train formation system, gaps arise between the individual wagons that are to form a wagon association. Gaps also arise when individual wagons drive onto wagons that are already on the track and the wagons that are already standing are moved forward as a result of the impulse maintenance. Mastering the formation of gaps is additionally made more difficult by compressing and re-expanding the buffers.
    It is therefore common practice to push the wagons located on a track together before the wagon association can be formed by connecting the couplings under the wagons. For a locomotive driver of a shunting locomotive used for this purpose, the shunting locomotive cannot be seen from the driver's cab, how far he has to push the first wagon of the later wagon association, i.e. the wagon that directly connects to the shunting locomotive, to push all wagons of the wagon association together so that they Buffer to buffer come to a standstill. The pushing together therefore requires the support of shunters who check whether all the carriages are in the desired position. It is not possible to automate train formation based on this procedure.
    There is therefore a need to provide a method for arranging wagons on a track section that enables automated train formation reliably.
    Disclosure of the invention In contrast, the method according to the invention for arranging carriages on a track section has the advantage that a shunting locomotive moves the carriages in response to a signal from a remote control sensor, the remote control sensor being arranged in a stationary manner in such a way that it monitors the track section. The fixed arrangement of the remote control sensor has the particular advantage that the positions of the cars can be detected without the position being able to be determined dependent on the fact that there must be a line of sight between the shunting locomotive and the cars.
    [0005] In the following, a remote control sensor is understood to mean any sensor that can detect objects that are in a field of view of the remote control sensor by detecting acoustic or electromagnetic waves that are emitted by the objects. In particular, the remote control sensor can be a sensor that actively emits the acoustic or electromagnetic waves and detects reflections of the acoustic or electromagnetic waves.
    The method according to the invention is advantageously used when the wagons are already on the track section before the shunting locomotive moves the wagons.
    It is advantageous if the wagons are brought to the track section by means of a drainage rock or a pushing operation.
    It is advantageous if, by moving the wagons through the shunting locomotive, the wagons are brought into a position which allows the wagons to be connected by coupling two adjacent wagons to form a wagon association. This is particularly possible if two adjacent cars are so close together that their buffers touch. Couplings of freight wagons are typically dimensioned so that the couplings of two neighboring wagons can be connected in such a case.
    It is advantageous if a compression path is determined by means of the remote control sensor before or during the movement of the car through the shunting locomotive, which the shunting locomotive has to travel in order to spend the car in a position that allows the cars to be coupled by coupling two adjacent ones Connect wagons to a wagon association. Stauchweg is the distance that the shunting locomotive approaching the wagons has to travel after touching the first wagon seen from it until all wagons are positioned on the track section in such a way that the buffers of two neighboring wagons touch each other. Approximately, the upsetting distance is the sum of the distances between two adjacent carriages on the track section. A determination of the upsetting path before the wagons move through the shunting locomotive enables a particularly precise determination of the upsetting path since the wagons are at rest at the time of the determination. Determining the upsetting distance during the movement of the cars through the shunting locomotive opens up the possibility of determining a remaining upsetting distance, which at any time indicates how far the shunting locomotive still has to travel in order to bring all of the cars into the position required for coupling.
    It is advantageous if after covering the upsetting path through the shunting locomotive it is checked by means of the remote control sensor whether the carriages are in a position that allows all carriages that are on the track section
    CH 714 451 A2, to connect two neighboring carriages to form a carriage association. In particular, the remote control sensor can be used to check whether a car located at the maximum distance from the shunting locomotive, i.e. the car that is to form the end of the car association, starts moving after contact between its buffers and the buffers of the immediately adjacent car, so that between the from the shunting locomotive the maximum distance from the wagon and the immediately adjacent wagon there is another gap.
    It is advantageous if a corrective diving path is determined by means of the remote control sensor, which the shunting locomotive has to travel in order to spend all the wagons that are on the track section in a position that allows the wagons to be coupled by coupling two adjacent wagons to connect a wagon association, whereby the determination of the corrective diving path takes place after the shunting locomotive has covered the upsetting path. The correction compression path is preferably determined using the same procedure as the determination of the compression path. In an advantageous development, the correction diving path is repeated, that is to say iteratively.
    It is advantageous if a speed of the shunting locomotive when covering the corrective diving path is limited to a value which is below a maximum permissible speed of the shunting locomotive for covering the upsetting path. The corrective diving path is covered by the shunting locomotive in the direction of the wagons. Limiting the speed of the shunting locomotive when covering the corrective diving path prevents the last wagon of the wagon association from becoming detached from the remaining wagons on the track section after a buffer contact. The value to which the speed is limited is advantageously determined experimentally.
    [0013] The method according to the invention is advantageously carried out using a signal from a large number of remote control sensors. The track section can be continuously monitored by a large number of remote control sensors, in particular if the large number of remote control sensors is arranged in such a way that the individual fields of view of the remote control sensors overlap in the area of the track section.
    A device that is set up to carry out each step of the method according to the invention is advantageous.
    It is advantageous if the device is such that the remote control sensor is a radar sensor or a video sensor or a lidar sensor.
    A device in which the remote control sensor is arranged next to the track section is advantageous. From this position, particularly efficient and robust monitoring of the track section to be monitored is possible.
    A device is advantageous which comprises a plurality of remote control sensors which are arranged in a stationary manner such that they monitor the track section. It is particularly advantageous to arrange the large number of remote control sensors in such a way that the viewing areas of the remote control sensors overlap in the area of the track section. This ensures complete monitoring of an entire route.
    Also advantageous are a computer program that is set up to carry out each step of the method according to the invention and a storage medium on which the computer program is stored.
    An exemplary embodiment of the present invention is explained in more detail below with reference to the accompanying drawing. It shows:
    Fig. 1 is a schematic representation of a device which is set up to carry out an embodiment of the inventive method.
    Brief description of the drawing Fig. 1 shows a schematic representation of a shunting locomotive (10) which is located together with carriages (20, 21, 22) on a track section (30). There is a distance (28, 29) in the form of a gap between each two adjacent carriages (20, 21, 22). The shunting locomotive (10) comprises a control unit (12), which in turn comprises a storage medium (14). The shunting locomotive (10) further comprises a receiving unit (16) which is connected to the control unit (12) via a signal line.
    Fig. 1 also shows a stationary device which is set up to monitor a track section (30). The device comprises a transmission unit (45) which is connected to a plurality of remote control sensors (40, 41, 42) via a signal line. The remote control sensors (40, 41, 42) are arranged in such a way that their respective field of view (46) points in the direction of the track section (30). For reasons of clarity, the field of view (46) in FIG. 1 is explicitly indicated with reference numerals only in the case of the remote control sensor 42.
    A connection between the control unit (12) and the remote control sensors (40, 41, 42) can be established by means of the receiving unit (16) and the transmitting unit (45).
    [0023] In a preferred development, the remote control sensors (40, 41, 42) are radar sensors.
    An exemplary embodiment of the method according to the invention is described below. The situation shown in FIG. 1 corresponds to the situation at the beginning of the exemplary embodiment of the method according to the invention described here.
    CH 714 451 A2 In a first step, the track section (30) is scanned using the signals from the remote control sensors (41, 42, 43) and the position and size of the carriages (20, 21, 22) are determined. The first step either takes place at a time when the shunting locomotive (10) is not in the field of view (46) of one of the remote control sensors (40, 41, 42), or the shunting locomotive (10) is used as a shunting locomotive based on specific backscattering (10) recognized. The shunting locomotive (10) is therefore in particular not regarded as a carriage.
    In a second step, the distances (28, 29) between the carriages (20, 21, 22) are determined by starting from the signals from the remote control sensors (40, 41, 42) the lateral distances between the carriages (20 , 21, 22) structures identified.
    In a third step, a compression path is calculated by adding up the distances (28, 29) between two adjacent carriages (20, 21, 22). In an advantageous further development, the upsetting path is then corrected by an empirical correction value, which can be determined empirically, for example, and takes into account the fact that buffers of the carriages (20, 21, 22) can be compressed, so that a length of the carriages (20, 21, 22) effectively shortened if at least some of the carriages (20, 21, 22) are pushed by the shunting locomotive (10).
    In a fourth step, the shunting locomotive (10) starts moving in the direction of the carriages (20, 21, 22). As soon as the shunting locomotive (10) has made contact with the first car (20), it continues its journey in the same direction and covers a distance that corresponds to the upsetting path. Establishing contact with the first carriage (20) can be detected, for example, by a vibration sensor located on the shunting locomotive (10). Alternatively, the establishment of the contact can also be detected by means of the signals from the remote control sensors (40, 41, 42).
    After the shunting locomotive (10) has shifted the first carriage (20) around the upsetting path in the direction of the further carriages (21, 22), the movement of the shunting locomotive (10) is ended. In a fifth step, the signals from the remote control sensors (40, 41, 42) are used to determine whether the carriages (20, 21, 22) are in a position which allows the carriages (20, 21, 22) to couple to a carriage assembly allowed. For this purpose, it can advantageously be determined whether the buffers of the carriages (20, 21, 22) touch. If it is determined in the fifth step that the carriages (20, 21, 22) are not in a position which allows the carriages (20, 21, 22) to be coupled to form a carriage assembly, a sixth step is carried out. Otherwise the procedure ends.
    In the sixth step, a correction dive path is determined by means of the signals from the remote control sensors (40, 41, 42). For this, the procedure of the third step is repeated.
    In a seventh step, the shunting locomotive (10) starts a movement again in the direction of the carriages (20, 21, 22) according to step four, the speed of the shunting locomotive (10) being limited to a value which is below a permissible maximum speed the shunting locomotive for covering the upsetting path lies. After the corrective diving path has been covered, the movement of the shunting locomotive (10) is ended.
    The fifth step is then carried out again. The method ends because the signals from the remote control sensors (40, 41, 42) have been used to detect that the carriages (20, 21, 22) are in a position that allows the carriages (20, 21, 22) to pass Coupling two adjacent wagons (20,21,22) to form a wagon group, the wagons (20, 21,22) are coupled to form a wagon group.
    [0033] The method according to the invention can be carried out, for example, by the control unit (12) of the shunting locomotive (10) by running a correspondingly configured computer program on the control unit (12). Alternatively, the method according to the invention can be carried out by a computing unit which forms part of the transmitting unit (45). Furthermore, as an alternative, the method according to the invention can be carried out by an external computing unit, which in particular can be a computing unit of a control center, in that a correspondingly configured computer program runs on the external computing unit.
