Definitions

  • the invention relates to a method for controlling the sequence of the cars disassembling railway train from a drain mountain of a marshalling yard the preamble of claim 1.
  • Such known system are used to distribute the wagons of a train to others Trains.
  • the routes of the running wagons (processes) on different Target tracks are to be collected and put together to form trains specified by switches (separating switches) and differentiated from one another.
  • a push-off locomotive moves the train to be dismantled (the dismantling unit) low speed to the drain mountain.
  • the approach of the disassembly unit goes into the push-off process about.
  • the first wagon on the mountain is uncoupled and over the Hilltop pressed.
  • On the slope behind the hilltop is the one that runs Waggon (sequence, forerunner, follower) accelerated and the trigger signal through Driving on contacts (mountain contacts) set to red.
  • the release for the next process is activated by switching the trigger signal on z. B. Displayed in white. So far, this switchover has only taken place when the first process (forerunner) has reached its target track and the the route of the Follower-defining switches have circulated. This way, between a safety margin is maintained on successive processes, which ensures that the wagon following the forerunner, which will soon be pulled off (Follower) did not collide with the forerunner or with a rotating switch.
  • the blocking length in the known methods is the length between the drain mountain or the waiting trailer and the exit of the separating switch predefined which of the forerunners to reach its target track has traveled.
  • the release of the process of the back-up is only then when all points that determine the route of the forerunner into the route of the successor determining position.
  • the separating switches at their output Provide sensors which detect the extension of a car, i.e. of the forerunner the turnout area (exit sensors). Through the exit sensor of the Isolation switch of the forerunner triggers the release signal of the backer.
  • the object of the invention is the performance of such a maneuvering system increase and without compromising security the process and distribution allow a larger number of wagons per unit of time.
  • the one in this application So-called corner impact, in which the chassis of a wagon with the in Circulating switch tongue collides, but also a collision of wagons in the area of the soft must be prevented.
  • the blocking length is now variable depending on the dynamic behavior of the wagons. Doing so can be essential denser sequence of processes is achieved and the process of the back-up is already released if the precursor is still in the distribution zone, i.e.: the Crossover to his target track has not yet been reached, but at least has not yet left Has.
  • the profile of the drainage hill is based on height and inclination as well as the Length of the respective distribution route taken into account. (Claim 3).
  • the respective dynamic behavior can e.g. thereby be characterized in that the time is entered into the memory Worst runner and the best runner between the summit and a fixed measuring point or between two fixed measuring points or between the summit or one Place a fixed measuring point below the summit and the individual separating switches.
  • the safety distance is the distance between the drain mountain and one of the switches chosen, which is preferred over the separating switch of the precursor lie.
  • a software module is stored in which the individual blocking lengths are dependent from the separating switches to be approached which lead to the respective target tracks are stored and available. (Claim 11).
  • the characteristics typical of the individual wagon and those for the route typical properties (see above) as well as the process characteristics of the Worst runner on the one hand and the best runner on the other hand preferably in theirs Relationship to the individual target tracks saved and for the control of the sequence operation
  • the buffering is used in maneuvering mode of forerunners and followers, i.e. moving the follower onto the forerunner Approved if damage to freight (cargo) or wagons is not expected is.
  • This embodiment of the invention makes the process operation more flexible in the sense of a shortening of the safety distances and an increase of the running frequency achieved without compromising security.
  • the method according to the invention then has the particular advantage of increasing performance the drain system, if separating switches further away from a forerunner must be started.
  • the lock length is even shorter in this case than the distance between the drain mountain and the separating switch that the follower has to approach, preferably plus the distance between the separating switch and exit of this separating switch.
  • the blocking length ensures that there is no collision of the follower in the for separating switches to switch him or the forerunner, especially no corner kick (in the sense defined above) with the switch, even if the individual turnouts are not secured by pull-in contacts and pull-out contacts.
  • the blocking length is therefore shorter than dimensioned so far.
  • the safety distance in this version is also dependent on Profile of the mountain (height, slope) and other dynamic factors such as in particular the characteristics typical of the individual wagon and those for the Characteristics typical for the route (see above) and the sequence characteristics of the Worst runner on the one hand and the best runner on the other hand for each process and each target track variably specified.
  • the axle counter which is the exit of the last axis of the predecessor at the end of the blocked length (in this application referred to as the "free-running axle counter" also signals the speed of the predecessor and redeems depending on this speed Signal from which e.g. the location of its drainage properties between best and
  • a measuring point is selected so that it is on the one hand guarantees the necessary security of the process operation, but on the other hand optimal short safety distances allowed.
  • the following further training adapts to the respective one desired function as well as the respective geographical conditions of the drain mountain, the distribution zone and the respective dividers and finish tracks.
  • Claims 13 and 14 typically serve the purpose of releasing and / or Trigger protective switch program.
  • Claim 14 typically serves the purpose of avoiding buffering in the target track, if an extremely bad predecessor of a well running successor is tracked, which is directed to the same target track.
  • Claim 15 enables the release of the wake alone depending on the determined speeds and the shortening of the safety distance the distance between the summit and the dodge.
  • Claim 16 permits an extreme reduction in the safety distance.
  • the possible control signal of the sensor or Measuring point also depends on its location. This is due to the design of the method according to claim 17 in any case largely prevented.
  • a measuring point for the dynamic properties of the process is assigned to each target track the dynamic properties that result from the target track, in particular the distance to be covered and its gradient, be taken into account by the choice of the location of the measuring point.
  • the location of the measuring point must also meet the security requirements Take into account. This is done according to claim 18 in that a minimum distance is determined from the empirically determined dynamic properties of worst and best processes.
  • the measuring point at the beginning of the blocking length is at a distance according to claim 18 and the measuring point at the end of the blocking length is a distance from the separating switch or - if a protective switch program is to be triggered - from the next Dodge, which ensures that even the fastest follower the slowest Forerunners in the remaining stretch between the end of the restricted stretch and the Cannot catch divider or dodge.
  • the evaluation of the signals according to claim 22 contributes to the uniqueness of the measurement results and control signals.
  • the invention makes it its task to find suitable control strategies the expiry mode, which provides the special possibilities which result from the invention according to claims 1 and 12, use.
  • the protective switch program includes one or more or all Points are changed, which are e.g. before a certain one Soft lying. In this way it is achieved that with the least possible Safety distance that must be maintained between two processes, however it is still possible to switch a dodge into which the follower dodge can to avoid a buffer or a corner kick (as defined above).
  • the protective switch program is shortened in the execution strategy of the blocked lengths included.
  • Protection switch program also triggered a buffering on a bad runner to prevent. In this case you have a mistake, but you avoid it damage to vehicles or cargo.
  • Suitable protective switch programs result from claim 29, which aim to to achieve a reduction in the safety distance in that, if necessary the forerunner or the successor is diverted to a track other than its destination.
  • a further increase in the drainage capacity should be taken into account even when the Running properties are achieved according to claims 24 to 27. If dependent a blocking length of the measurement signal individually for the affected precursor is set (claim 24), one achieves an optimally short blocking length below Consideration of all security issues. This makes it possible, even with the Detection of bad runners does not absolutely block the distribution zone but the next process in adaptation to the special features of the distribution zone and the Release dynamics of the predecessor as soon as possible.
  • the release signal is then issued by a presence sensor, which is a has a predetermined position at the end of the blocking length and preferably accordingly claims 9 and 10 is positioned.
  • Suitable presence sensors and speed sensors are available e.g. in the form of double electromagnetic sensors according to DE-C1 43 25 406 (Tig 9201). These are also used as presence sensors, especially as limit sensors, i.e.: input sensors and output sensors (free moving sensors) Each turnout is used, the allocation of the turnout by recording the incoming Report axes and the extending axes. These sensors can also serve as speed sensors, so that further equipment the distribution zone is not required. All that is essential is the measurement sign which of the existing sensors are used for sequence control. It should be noted that a sensor is arranged behind each separating switch, which gives a signal when the wagon leaves the area of influence of the sensor Has. It can be z. B.
  • the individual blocking lengths are dimensioned so that, on the one hand it is ensured that even badly running precursor wagons are safe have left the separating switch to be switched for the trailer before the Release signal and thus the switching of the switch to be switched for the trailer he follows.
  • the blocking length is shortened in such a way that the pull-off speed the haul-off locomotive increased and the number of wagons distributed can be increased.
  • the invention has the advantage on the one hand that the running frequency of the wagons can be significantly increased in a shunting system without intervention in the shunting system itself. No loss of route safety is accepted, on the contrary: on the one hand, the lengthening of the blocking length of the trailer leads, which is done according to the invention by a bad precursor, that this also delays the process of all subsequent processes accordingly and thus ensures it becomes that no successor can catch up with the forerunner.
