Definitions

  • the individual points in the so-called distribution zone are set for the individual selective separation of the processes in such a way that a route leading to the respective predetermined directional track results for the respective process.
  • care must be taken to ensure that subsequent processes do not lead to impact or corner impacts due to processes that are too slow.
  • This also applies in particular in the area of the distribution switches, which are usually marked by a boundary symbol.
  • the boundary sign indicates the point or area up to which each branch track may be occupied in the case of tracks converging at a switch, without vehicles on the blunt side of the switch coming into contact with one another.
  • a branch track may only be driven on from the pointed side of the switch if the switch in question has been cleared without boundary marks, ie the other branch track is free of boundary marks.
  • clearing of a point without any boundary marks is usually detected by appropriate sensors, which can be, for example, axle counting points of an axle counting system, for example in the form of rail or track contacts.
  • document EP 1 129 922 A2 describes a method for distributing the wagons on different tracks from the distribution zone using successive separation points.
  • document DE 101 08 300 C1 describes a maneuvering process that enables a vehicle to be started as soon as the speed of a previous vehicle has been measured and the correct position on the route has been determined. The measured speed is compared with a previously reported reference speed of a vehicle with good driving characteristics.
  • the present invention is based on the object of specifying a particularly powerful, flexible and at the same time realizable method for operating a marshalling control system that can be implemented with comparatively little effort, particularly with regard to determining the absence of boundaries of points in the drainage system.
  • this object is achieved by a method for operating a shunting system, wherein a first sequence in the form of a first running car or a first running car group is detected by means of a sensor device arranged in the area of a branching switch, taking into account at least the location of the sensor device and the At the time of the detection of the first axis of the first sequence, a clearing time is determined at which the first sequence is one of the location of the sensor device deviating clearance reporting point with the last axle or with all components of the process completely passed and so that the switch will have cleared without boundary marks in relation to a clearing point, for a subsequent second process in the form of a second expiring wagon or a second expiring wagon group, it is determined whether it is in the event a repelling position of the switch that has changed compared to the first process will come into contact between the two processes before the time of clearing, and if this is not the case, the switch will be switched to the repelling position if it can be adjusted, or the repelling position in the case of one
  • a first sequence in the form of a first running car or a first running car group is detected by means of a sensor device arranged in the area of a branching switch.
  • the sensor device can be a device of any type which is known per se and which is suitable for detecting the first sequence.
  • a sensor device is preferably used that is also used for other purposes, i.e. not exclusively used to detect the first sequence within the scope of the method according to the invention.
  • a clearing time is now determined taking into account at least the location of the sensor device and the time at which the first sequence was detected.
  • the clearing time is the point in time at which the first sequence completely passes a clearance reporting point deviating from the location of the sensor device and thus the switch will have cleared without any boundary marks in relation to a clearing point. This means that it is not the sensor device itself that detects the clearing of the switch without any boundary characters, but rather, taking into account at least the location of the sensor device and the time at which the first sequence is detected, it is determined when the first sequence is the one from the location of the sensor device will have completely passed the deviating free reporting point.
  • the clear reporting point is characterized in that as soon as the first sequence has completely passed the clear reporting point, the switch is cleared without any boundary marks in relation to the clearing point or is treated as cleared without boundary marks.
  • the free reporting point is a “virtual” free reporting point in that at this point itself no sensor system is provided for detecting that the first sequence has been completely passed. Instead, taking into account at least the location of the sensor device and the time at which the first sequence was detected by the first sensor device, it is determined when the first sequence will have completely passed the "virtual" free reporting point. Depending on the respective implementation, “completely happened” can mean that all components of the process are actually located behind the clear reporting point, viewed in the direction of flow.
  • the free reporting point can also be defined analogously, for example, to the functionality of an axle counting point, in that the switch is cleared with no boundaries in relation to the clearing point when the last axis of the first sequence has passed the free reporting point.
  • the latter approach in which vehicle and buffer overhangs can be taken into account at a given clearing point by specifying the location of the free reporting point, allows the free reporting point to be treated similarly to a real axle counting point within the framework of the control of the sequential system.
  • the location of the free reporting point can be determined or configured, for example, by a corresponding parameter.
  • the location of the sensor device can also be taken into account indirectly as part of the determination or prognosis of the clearing time. This includes, for example, the case that the distance between the sensor device and the clearance reporting point is taken into account when determining the time of clearing.
  • the third feature of the method according to the invention it is determined for a subsequent second sequence in the form of a second running car or a second running car group whether there is a contact between the two in the case of a different, repellent position of the switch before the time of clearing Processes will or would come. In this step it is checked whether it is possible to switch the switch without the risk of a corner joint between the two successive processes.
  • the switch is then switched to the repellent position in the event that there is no risk of contact between the two processes.
  • An additional prerequisite here is that the switch as such can be adjusted in such a way that it is not occupied by one of the two processes, especially in the area of its moving parts, in which case the corresponding process could derail when the switch is switched.
  • the switch has already been switched at a previous point in time. In this case, as a result of the method, the repellent position is retained, since in this case too, in accordance with the previous prognosis or determination, it can be assumed that there will be no undesired contact between the two processes.
  • the method according to the invention has the advantage that, in relation to clearing of the switch without boundaries, it allows the use of a clearing point that is not marked or identified by a corresponding sensor device as a reference point. This means that the most favorable permissible clearing point can be used in the context of the automatic operation of the drainage system, even if no sensor device is available for its detection.
  • a correspondingly favorable clearing point is usually characterized by the fact that it ensures clearing of the switch without boundary marks and, at the same time, the shortest possible distance to the point center.
  • the method according to the invention advantageously avoids any additional sensor devices that may otherwise be required due to the use of a “virtual” free reporting point.
  • the method according to the invention can preferably be developed in such a way that the switch remains in an unchanged position compared to the first process or in a previous position in the event that if the switch is in a repellent position according to the determination made, the two processes come into contact If the switch has already been changed, it is returned to the unchanged position in the event that it can be adjusted.
  • the system can react to the fact that the switch is not switched or the switch is opened in the event that the switch is that it was previously placed in a repellent position, in the event that it can be adjusted, it will be returned to the position that has not changed in comparison to the first sequence.
  • buffering of the two processes is thus advantageously permitted, since this is preferable to a corner joint with regard to possible damage or derailment of the processes.
  • the desire to switch the switch to the rejecting position can have any reasons or causes related to the operational sequence. For example, it is conceivable that the paths of the two processes separate at the switch and that this should therefore be switched to the repellent position.
  • the switch is switched to the rejecting position for the purpose of avoiding a buffering of the second sequence to the first sequence as a protective switch or the rejecting position of the switch is retained for this purpose.
  • a protective switch or the rejecting position of the switch is retained for this purpose.
  • the method according to the invention can preferably also be designed in such a way that the method is triggered in that, in the context of monitoring the operation of the drainage system, it is recognized that this is due to an abnormal sequence behavior of the first sequence and / or the second sequence, the second sequence threatens to catch up with the first sequence.
  • the steps of the method according to the invention in particular the determination of the time of clearing and the determination of whether there will be a contact between the two processes before the time of clearing, in the case of a changed, repellent position of the switch compared to the first process, only if in As part of the monitoring of the operation of the drainage system, it has been recognized that the second sequence threatens to catch up with the first sequence and thus buffer the two sequences.
  • the time of clearing and / or the location of the second process at the time of clearing is determined taking into account at least one characteristic variable specific to the respective process. This is advantageous because it allows the accuracy of the determination of the clearing time or the location of the second sequence at the clearing time to be improved. As a rule, the greater the accuracy, the more specific parameters are taken into account for the respective process in the prognosis or determination.
  • the method according to the invention can preferably also be developed in such a way that the at least one characteristic variable specific to the respective sequence is determined within the scope of the sequence operation and / or is provided by a scheduling system.
  • This has the advantage that it is ascertained, ie measured, for example, within the framework of the sequence operation or parameters specific to the respective sequence derived from measured variables as well as corresponding specific parameters provided by a disposition system are suitable for optimizing the accuracy of the method.
  • the at least one characteristic variable specific to the respective sequence can in principle be any variable.
  • the method according to the invention is developed in such a way that the at least one characteristic variable specific to the respective process comprises at least one of the following values: length of the process, buffer overhang of the process, weight of the process, running resistance of the process, current and / or future speed of the process, current and / or future acceleration of the process, current and / or future rolling resistance of the process.
  • the variables mentioned are those that have or can have a significant influence on the determination of the clearing time or the determination of whether there is a risk of contact between the two processes in the event of a changed position of the switch.
  • the variables mentioned are advantageously those which are often already used to monitor and control the operation of the drainage system and can therefore be used without additional effort in connection with the method according to the invention.
  • it enables the recording and technical observation of the speed behavior of the processes, for example with the help of axle counting systems with axle counting points provided for this purpose, with knowledge of the rolling and running resistance values determined in the course of operation, to calculate the current and future acceleration or the running behavior of the processes or to forecast. In this way, it can be determined with high accuracy at what point in time the second sequence will reach the switch and whether this will be cleared at this point in time with reference to the clearing point by the first process without any boundary marks.
  • the method according to the invention can furthermore be designed in such a way that a sensor device is used which is provided for reporting the switch as cleared of boundary signs in the event of a maneuvering operation with routes.
  • a sensor device is used which is provided for reporting the switch as cleared of boundary signs in the event of a maneuvering operation with routes.
  • the sensor device and the clear reporting point can be arranged with respect to one another as desired in the area of the switch. This means that either the location of the sensor device or the free reporting point can be closer to the center point of the switch.
  • a sensor device is used in the area of a branch track of the switch, the location of the sensor device being further away from the center point of the switch than the clear reporting point.
  • any type of sensor device can be used within the scope of the method according to the invention. It is only essential here that it is designed to detect the first sequence or the first axis of the first sequence.
  • an optical sensor device for example in the form of a light grid, can be used to detect the occurrence of the first sequence in an optical monitoring area.
  • axle counting point is used as the sensor device.
  • axle counting points which are also referred to as wheel sensors or rail contacts, are widespread in particular in connection with axle counting systems in sequence systems and are usually used there both to detect the axes of the processes and to determine the speed of the processes.
  • the first sequence is detected on the basis of its first axis. This is especially the case using an axle counting point as a sensor device is advantageous.
  • the points in time of the detection of the further axes of the first sequence can also subsequently be used with regard to an improved determination of the time of clearing or a possible contact between the two sequences.
  • the method according to the invention can preferably also be developed in such a way that the determination of the time of clearing and / or the determination of whether the two processes will come into contact before the time of clearing in the case of a repellent position of the switch that has changed compared to the first process
  • Use of time-distance lines for at least the first and / or last axis of the respective sequence takes place. This is advantageous because the use of time-distance lines is a well-known, tried-and-tested procedure for monitoring, forecasting and simulating processes in process plants.
  • the clear reporting point can also be used to plan the sequence operation within the framework of a prognosis or simulation in such a way that the first sequence has cleared the switch with respect to the clearance point before the second sequence clears the switch or reached the clearance point.
  • the prognosis or simulation of the process operation can take place both before the processes actually run and also wholly or partially during the process.
  • the use of the free reporting point in the context of a corresponding forecast or simulation can result in advantages with regard to the drainage performance and / or the maneuvering quality of the drainage system.
  • the invention also relates to a control device for a shunting system.
