Definitions
- Processes respectively opened or unhooked. Each time the center of gravity of a process has passed a mountain peak of the drain, the process accelerates due to the gravitational force acting on it and thus detaches itself from the residual drag, i. from other wagons to be pushed off.
- the gaps or distances arising between the processes are necessary in order to be able to change over points and thus on the one hand to control each process into its corresponding target track and on the other hand to prevent any start-up or collision of successive processes.
- the withdrawal speed predetermined by a shunting locomotive is generally calculated for each sequence in such a way that gaps arise between successive sequences whose length only corresponds to the minimum length required in each case. How quickly the corresponding Lü ⁇ can be made between processes actually occur and how long they are for the time being, depends rule of

- a kinematic measurement variable of the sequence based on at least one corresponding measured value relating to the kinematic measured quantity of the sequence, using at least one reference value, it is possible to make the detachment behavior of the sequence plausible.
- the separation behavior of the sequence corresponds to expectation.
- the detachment behavior of the process from the at least one further vehicle ie from a stripping locomotive, a precursor and / or a trailer, is made plausible in such a way that it can be assumed that no
- the inventive process also has the advantage that rangiertechnische flow systems often already have Sen ⁇ sor drivingen which are additionally suitable for their actual or previous function to the to at least one measured value of the kinematic measurand to capture.
- the inventive method is such further developed in that the at least one measured value to at least one of the following ki ⁇ nematic metrics relates: at least one Befahrungs- time, at least a period of time, at least one Geschwin ⁇ speed, at least one acceleration.
- the kinematic variables mentioned allow a statement about the detachment behavior of the respective sequence. In practice, it depends on the particular circumstances, such as the sensor devices available in the system or the algorithms used to control the system, whether at least one driving time, at least one time period, at least one speed or at least one acceleration ⁇ used as a kinematic measure become.

- the acceleration of the process at a predetermined time, in a predetermined situation or at a predetermined location has reached or exceeded the minimum acceleration.
- the specific value of the minimum acceleration depends on the particular circumstances and can be, for example, 0.1 m / s 2 .
- a limit value for a maximum acceleration is used as reference acceleration. In this case can be tested, for example, that the Accelerati ⁇ supply of the process is within a permissible or Plausib ⁇ len value range.
- the inventive method can also be designed such that the plausibility of the Ablöseverhal ⁇ least the flow of the at least one other vehicle is made after the process should have scheduled to reach the free run.
- This offers the advantage that the process should accelerate at this time, whereby a reliable plausibility of the detachment behavior of the Ab ⁇ running of the other vehicle is possible.

- any device for detecting wheels or axles of a rail vehicle is referred to as a wheel sensor.
- the wheel sensor can have, for example, at least one transmitting device and at least one receiving device.
- wheel sensors in the sense of the present invention are also known under the terms "point of delivery”, “axle counting point”, “rail contact” or “track contact”.
- the inventive method may also be such a serious nature that a sensor device is used which comprises at least one of detecting a start of a sequence ⁇ process and / or at least one distances for detecting axis serving wheel sensor.
- a sensor device which comprises at least one of detecting a start of a sequence ⁇ process and / or at least one distances for detecting axis serving wheel sensor.
- the information includes provided for between successive points of separation processes. This is partly because the separation points provided between successive sequences have a significant influence on the kinematic behavior of the respective sequence.
- further information can be taken into account, such as length, number of axles and / or weight of the individual cars or processes.
- the Plausibili ⁇ tion of the release behavior of the process is such that it is required that in a situation in which a minimum has been paid detected by axes and according Decompose ⁇ list, the flow to at least two thirds of its Length has already passed the summit of the professionberg, the acceleration ⁇ tion of the process is greater than a minimum acceleration. Through the appropriate conditions this is ensured that the focus of the process should have already passed the peak and the process should therefore because we ⁇ kenden gravity already accelerated.

- the at least one measured value is detected by the sensor device no further than 20 meters, in particular not more than 10 meters, behind a summit of a drainage hill of the drainage system.
- the respective distance information to the Abiaufraum relates, so that the respective sequence when sen Erfas ⁇ at least one measurement value as a rule will have the Berggip- fei already at least partially passes the.
- the invention also includes a control device for a technical process drains.
- the control device according to the invention is characterized in that it comprises means for carrying out the method according to the invention or for carrying out one of the aforementioned preferred developments of the method according to the invention.

- the process 40 is the "front car” or "precursor” and the process 30 is the “rear” car or "trailer”.
- a peak of the profession is indicated in Figure 1. This means that has already moved to the position shown in Fi gur 1 ⁇ situation the carriage 42 is fully over the peak 50 and also the carriage 41 already approximately half. As indicated by a corresponding gap between the processes 30 and 40, this has the consequence that the process 40, ie the group of cars consisting of the carriages 41 and 42, has detached from the drain 30 and is now caused by the on the flow 40 acting gravity to the right in the direction of a distribution zone bezie ⁇ tion as appropriate direction tracks moved.
- the Abdschreib horrinsky of the subsequent ⁇ the process 30 is selected such that the spatial gap between the two processes ⁇ 40 and 30 is sufficiently large in order to make required point settings and a touch of the processes 40 and 30 during their journey along to avoid the Weganläge.
- An essential prerequisite for this is that the process 40 dissolves from the process 30 in the expected manner.
- a late opening of the carriage coupling at the point of separation between the carriages 41 and 32 would result in that the drain 40 could not accelerate or only late free and thus would not create a sufficient gap between the drains 40 and 30.
- the process 40 would accelerate later than expected even if the group of cars concerned were longer than planned because a separation point was under-set.
- the flow conditioning a Sen ⁇ sor adopted 60 in the form of at least one wheel sensor on.
- the sensor device 60 is shown in Figure 1 for reasons of clarity such that it has only ei ⁇ nen wheel sensor.
- the sensor device 60 can also comprise a plurality of, in particular two, wheel sensors.
- the wheel sensors in question preferably have a spacing which permits an accurate determination of the speed of the respective axle on the basis of the driving times detected by the two wheel sensors.
- the two wheel sensors of the sensor device 60 can have, for example, a distance of 75 cm from each other.
- FIG. 1 is merely a schematic sketch. This means in particular that positions and downs ⁇ states of the components shown not scale or meet the typical practice values.
- the position of the sensor device 60 may coincide with the peak 50 of the professionberg.
- mountain contacts which are used to detect of the start of the discharge process and the start of the Achsv Introduceung and under the procedure described in the following in addition to a plausibility check of the release behavior of the process 40 of the following flow 30 may be used.
- a corresponding "multiple use” is conveyorge ⁇ starting advantageous that an installation of additional measurement ⁇ technology for the realization of the method is vorteilhafterwei- se avoided.
- the drainage system 10 is now such operated, that by means of the sensor device 60 at least one measured value is detected, which relates to a kinematic variable of the sequence 40.
- the at least ⁇ at least obtain a reading on a kinematic measure in the form of at least one Befahrung time point, at least ei ⁇ ner time period, at least one speed and / or ⁇ minimum acceleration.
- measured values in the form of driving times are recorded for each axis from times when the sensor device 60, which preferably comprises the first two wheel sensors on the discharge hill, according to the above explanations.
- control means can now points on the basis of Befahrungszeit- and the known distance of the wheel sensors of the sensor device 60 (or in the case of a single double sensor from signals received from the two sensor systems of the double sensor detected Befahr solicit and the known Abstan ⁇ of the sensor systems) for each of the axes of the process 40, the speed can be determined. Based on the VELOCITY ⁇ speed values of successive axles an acceleration value of the sequence relationship 40 may then ⁇ as determined at least be calculated.
- the control ⁇ means a plausibility check of the release behavior of the flow 40 of the other vehicle 30 in the form of nachlau ⁇ fenden sequence performed. This is done as part of the loading signed embodiment in the form that a comparison of the at least one acceleration value determined from the detected measurement values in the form to passing over points in time is made a reference value in the form of a Refe ⁇ ence acceleration with said at least.
- the at least one reference acceleration can also be referred to as the acceleration threshold value. In the reference acceleration, this is a minimum acceleration, which may be, for example, 0.1 m / s 2 .
- a decision as to whether the separation behavior of the ex ⁇ barrel 40 is assessed as plausible, is preferably in a situation in which the process 40 as scheduled relational example should have reached in accordance with a previous forecast to run free.
- the reasonableness ⁇ capitalization occurs the release behavior of the flow 40 of the at ⁇ least one further vehicle 30 while also taking into account a cut list, the information about between the consecutive sequences 40 and 30 provided separating points, and the number of the axes of the processes 40, 30 to - sums up. This makes it possible to take into account in the plausibility check that a separation point is provided between the processes 40 and 30.
- the Ab ⁇ dissolution behavior of the flow 40 from the drain 30 (or gegebe ⁇ appropriate, a further arranged before the expiration flow 40) is evaluated as implausible. This means that there is a fault, such as in the form of a missing separation point or a delayed opening of a central buffer coupling. To indicate this, a warning signal is output; Furthermore, the sequence operation is stopped. Depending on the In addition, further protective measures can be initiated or initiated. If, however, according to a rule, the detachment behavior of the sequence 40 is assessed as plausible by the further vehicle or the sequence 30, no special reaction is required, ie the sequence mode can be continued normally.
- a further transmitter sor worn in Figure 1 is indicated 70, which also comprises a Radsen ⁇ sor or more wheel sensors.
- this further Sen ⁇ sor driving 70 which may comprise for example, two arranged in the region of a light grid for the separation points detection Radsenso ⁇ reindeer, could alternatively further to or in conjunction with the sensor device 60 in the procedure described above for checking the plausibility of the release behavior of the flow 40 of the Vehicle 30 can be used.
- FIG. 2 shows, for a further explanation of the exemplary embodiment of the method according to the invention, a diagram with a representation of acceleration values as a function of the location.
- a lower limit value 110 is indicated as an upper limit value 120 of the acceleration a of the sequence 40 as a function of the location s.
- the lower limit 110 and the upper Grenzwer ⁇ tes 120 excluded values portions 130 and 140 which are ⁇ indicated in Fi gur 2 by a corresponding hatching.
- these excluded value ranges 130, 140 lie ⁇ ing value pairs should not normally occur in the operation sequence and would indicate in the event of their occurrence on an implausible release behavior of the process 40 of the process 30.
- a value in the excluded value range 130 indicates that the process 40 has resolved from the process 30 later than expected.
- the reason for this may be a missing separation point, a too late release of the coupling between the processes 40 and 30 or poor running properties of the process 40.
- a measured value in the off ⁇ closed range 140 would mean that the flow 40 has resolved earlier than expected from the drain 30th The reason for this may be an incorrectly placed separation point in the form of an additional separation point, a separation point set too close to the tip of the inlet or, if appropriate, also good running properties of the outlet.
- Wür ⁇ de indicate an acceleration value of the flow 40 in one of the out ⁇ closed ranges of values 130 or 140 to an implausible or defective separation behavior of the process 40 of the flow 30th
- a warning signal would then be output by the responsible control device and the sequence operation would be stopped. This is to avoid dangerous situations due to insufficient gaps between successive processes as well as possibly resulting collisions or false runners.
- Protective measures such as in the form of a protective softening done.
- an examination of the acceleration a of the process 40 at different locations s or even at a location s can take place.
- the latter can be defined, for example, in that the center of gravity of the process 40 already has the Have passed summit 50 of the Schwarzberg and should have gone into free run.
- the sensor device 60 may, for example, comprise at least one radar sensor.
- the method according to the invention has the particular advantage that an implausible detachment behavior of successive processes 40, 30 can be recognized early and reliably.
