Description

In technical waste disposal systems, wagons or groups of wagons, which are also referred to as drains, are sorted into different directional tracks from a mountain track using the gravity acting on the drains. In the sense of efficiency and reliability, this usually involves a far-reaching automation of the operation of the drainage system. An automatic control system suitable for this purpose is known, for example, from the company publication "Automation System for Train Forming Systems Trackguard Cargo MSR32 - Greater Efficiency and Safety in Freight Traffic", Order No .: A19100-V100-B898-V2, Siemens AG 2012. As part of a Laufwegsteuerung the known system u.a. System functions for the early detection of bad-walkers, for running monitoring, for standstill monitoring as well as for detecting inadmissible wheel sensor messages.

In the operation of a technical draining plant, the individual points are placed in the so-called distribution zone for individual selective separation of the processes such that there is a leading to the respective predetermined direction track leading path for each process. With regard to successive operations, care must be taken in normal operation as well as in the event of an abnormal run-off behavior or disturbances in the maneuvering operation that subsequent runs are not the result of too slow processes for casserole or corner impacts. This is especially true in the field of distribution points, which are usually marked by a border. In this case, the border mark indicates the point or area up to which each branch track may be occupied in tracks converging on a switch, without causing any mutual contact of vehicles on the blunt side the switch can come. In the case of drainage operation, this means that a branch track may only be driven from the pointed side of the turnout if the turnout concerned has cleared without a boundary, ie the other branch track is free from cross-border markings. In automatic sequence operation, a landmark clearing of a switch is usually detected by corresponding sensors, which may be, for example, axle counting points of an axle counting system, for instance in the form of rail or track contacts.

The present invention has for its object to provide a particularly efficient in terms of determining the borderline freedom of points of the drainage system particularly powerful, flexible and at the same time with comparatively little effort feasible method for operating a technical draining plant.

This object is achieved by a method for operating a technical draining plant, wherein a first sequence in the form of a first expiring carriage or a first expiring car group is detected by means arranged in the region of a branching switch sensor device, taking into account at least the location of the sensor device and the Timing of detecting the first sequence, a clearing time is determined at which the first process has a completely different from the location of the sensor device Freimeldedepunkt completely and thus cleared the switch with respect to a Räumpunkt borderless, for a subsequent second flow in the form of a second expiring car or a second expiring group of wagons is determined whether it will come in the event of a changed in comparison to the first course, repellent position of the switch before the Räumzeitpunkt to touch the two processes, and if this is not the case, the switch is switched in the case of their ability to adjust to the repellent position or the repellent position is maintained in a previously made changeover of the switch.

According to the first feature of the method according to the invention for operating a technical draining system, a first sequence in the form of a first draining wagon or a first draining wagon group is detected by means of a sensor device arranged in the region of a branching switch. In this case, the sensor device may be a device of any desired type known per se for detecting the first sequence. Preferably, such a sensor device is used, which is also used for other purposes, i. not exclusively for detecting the first process in the context of the method according to the invention.

According to the second feature 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 of detection of the first sequence. In this case, the broaching time is the point in time at which the first course completely passes a free-reporting point deviating from the location of the sensor device and thus the crossover has cleared border-free in relation to a broaching point. This means that the sensor device itself does not detect the landmark-free evacuation of the switch, but is determined taking into account at least the location of the sensor device and the time of detecting the first sequence, when the first process will have completely passed the Freimeldepunkt deviating from the location of the sensor device. In this case, the free-reporting point is characterized in that as soon as the first sequence has completely passed through the free-reporting point, the switch has been cleared border-free in relation to the fouling point, or is treated as having been cleared of borderline markings. In this case, the free-reporting point is a "virtual" free-reporting point in that, at this point, no sensor system is provided for detecting complete passage of the first sequence. Instead, taking into account at least the location of the sensor device as well as the time Detecting the first sequence by the first sensor device determines when the first sequence will have completely passed the "virtual" free-reporting point. Depending on the particular implementation, "completely happened" may mean that, in fact, all components of the process are located downstream of the safety signal point in the direction of flow. Alternatively, however, the free-reporting point can also be defined analogously to, for example, the mode of operation of an axle counting point in that the points are already cleared border-free in relation to the fouling point when the last axis of the first sequence has passed the free-reporting point. The latter procedure, in which vehicle and buffer overhangs can be taken into account by specifying the location of the free-reporting point for a given fouling point, makes it possible to treat the free-reporting point similar to a real axle counting point as part of the control of the outflow system. Specifically, the location of the free-reporting point can be defined or configured, for example, by a corresponding parameter.

As part of the determination or prognosis of the clearing time, the location of the sensor device can also be taken into account indirectly. This includes, for example, the case that the distance between the sensor device and the free reporting point is taken into account as part of the determination of the clearing time.

According to the third feature of the method according to the invention is determined for a subsequent second flow in the form of a second expiring carriage or a second expiring car group, if it changed in comparison to the first course, repellent position of the switch before the Räumzeitpunkt to a touch of the two Procedures will or would come. In this step, it is thus checked whether a switchover of the switch is possible without the risk of a corner kick between the two successive sequences.

According to the last step of the method according to the invention, then, in the event that there is no threat of corresponding contact between the two processes, the switch is changed over to the repellent position. An additional prerequisite here is that the switch as such is adjustable to the effect that it is not occupied with one of the two processes, in particular in the area of its moving parts, in which case it could come with a change of the switch to a derailment of the corresponding process. In addition, the situation is conceivable that the switch has already been converted at a previous date. In this case, as a result of the method, the repellent position is maintained, since in this case as well, according to the preceding 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 it permits the use of a fouling point not marked or marked by a corresponding sensor device as a reference point with respect to a landmark clearing of the switch. This means that in the context of the automatic operation of the drainage system the most favorable permissible fouling point can be used, even if no sensor device is available for its detection. In this case, a corresponding favorable Räumpunkt is usually characterized by the fact that it ensures a border-clearing of the switch and at the same time has the shortest possible distance to the middle of the switch. The method according to the invention advantageously avoids any additional sensor devices that may be required due to the use of a "virtual" free-field point. This results in both in terms of the saved hardware costs, such as in terms of production, installation and operation of the relevant sensor devices, as well as in relation to the required for incorporation of appropriate additional sensor devices in the flow control expenses, for example, by taking into account the free field logic, considerable advantages.

Preferably, the method according to the invention can be developed in such a way that the switch remains in a position that is unchanged in comparison with the first sequence, or in the case of a previous one, in the event that, in the case of a repelling position of the switch according to the determination made, the two processes come into contact already done switching the switch is reset in the case of their ability to adjust to the unchanged position. In the event that it is recognized in the process that it would come in case of repellent position of the switch in all likelihood to contact the two processes, it can thus be reacted to the effect that a switchover of the switch is omitted or the switch in the event that it has previously been placed in a dismissive position, in the case of its ability to be placed back into the unchanged position compared to the first. In the case of imminent corner joints thus advantageously buffering the two processes is allowed, since this is preferable to a corner joint in terms of possible damage or derailment of the processes.

Basically, the desire to change the switch in the repellent position, any, due to the expiration of reasons or causes have. So it is conceivable, for example, that separate the paths of the two processes on the switch and these should therefore be converted to the repellent position.

According to a further particularly preferred embodiment of the method according to the invention, the switch for the purpose of avoiding Aufpufferns the second sequence is switched to the first sequence as a protective switch in the repellent position or maintain the repellent position of the switch for this purpose. In particular, in the case of an abnormal execution behavior of the first process, the situation may arise in practice that buffering of the second process threatens the first process, which in this case may also be referred to as "bad runner". As this causes damage Both the transported goods as well as the respective processes itself can come, there is basically the desire to avoid an appropriate buffering as far as possible. This can now be done in such a way that the switch is switched to repellent position in order to achieve a separation of the paths of the two processes in good time before a possible Aufpuffern. Although this usually leads to the second process becoming a "false-runner" in that it is sorted into another directional track instead of the intended directional track. However, despite the resulting maneuvering this is usually preferable to buffering the two processes, so that the placement of a protective switch is an essential protective function of the operation sequence. In connection with the method according to the invention, it is possible in this case, also or in particular for this function in the determination or prognosis, whether the first sequence will have cleared the switch with respect to the fouling point in a timely manner, to use the free-reporting point deviating from the location of the sensor device. This results in the case of the protective softening position, the previously mentioned in connection with the inventive method significant advantages.

Preferably, the inventive method can also be configured such that the method is triggered by the fact that it is detected in the context of monitoring the operation of the drain system that due to an abnormal flow behavior of the first flow and / or the second flow, a recovery of the first flow through the second course threatens. Advantageously, the steps of the method according to the invention, in particular the determination of the Räumzeitpunktes and determining whether it is in the case of a changed in comparison to the first course, repellent position of the switch before the Räumzeitpoint come to a touch of the two processes, only if As part of the monitoring of the operation of the drainage system has been recognized that a request for the first flow through the second sequence and thus a buffering of the two processes threatens. As a rule, there is a need for a protective softening position here in particular in that the first sequence has an unexpectedly poor flow behavior and therefore will not clear the distribution zone in time for a follower. Alternatively or additionally, however, it is also conceivable that the second sequence has an unexpectedly good flow behavior, ie approaches the first sequence faster than expected.

According to a particularly preferred development of the method according to the invention, the clearing time and / or the location of the second run is determined at the time of broaching with further consideration of at least one characteristic variable specific to the respective run. This is advantageous since this makes it possible to improve the accuracy of the determination of the clearing time or of the location of the second run at the time of broaching. Thus, the accuracy will generally be greater, the more specific characteristics are taken into account in the prognosis or determination for the respective process.

Preferably, the method according to the invention can furthermore be so pronounced that the at least one parameter specific to the respective sequence is determined in the context of the sequence operation and / or provided by a scheduling system. This has the advantage that both as part of the sequence operation determined, i. For example, measured or derived from measured variables, specific for the respective sequence characteristics as well as provided by a disposition system corresponding specific characteristics are suitable for optimizing the accuracy of the method.

The at least one parameter specific to the respective sequence can in principle be of any desired size.

According to a further particularly preferred embodiment, the method according to the invention is developed in such a way that the at least one parameter specific to the respective sequence comprises at least one of the following: length of the sequence, buffer overflow of the sequence, weight of the sequence, running resistance of the sequence, 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. This is advantageous since the variables mentioned are those which have or can have a significant influence on the determination of the clearing time or the determination of whether the two processes are in danger of being touched in the event of a changed position of the switch. At the same time, the variables mentioned are advantageously those which are often already used anyway for monitoring and controlling the operation of the drainage system and thus can be used without additional effort in connection with the method according to the invention. In this case, for example, the detection and technical observation of the speed behavior of the processes, for example with the aid of axle counting systems with axle counting points provided for this purpose, under the knowledge of rolling and running resistance values determined in the context of the sequence operation, makes it possible to calculate the current and future acceleration or the running behavior of the processes or to forecast. As a result, it can thus be determined with high accuracy, at which point in time the second sequence will reach the point and whether it will be cleared borderline-free by the first sequence at this point in time with respect to the fouling point.

Preferably, the inventive method may further be configured such that a sensor device is used, which is intended to report in the case of a maneuvering with driveways the switch cleared as a landmark. This offers the advantage that in case of a shunting operation with driveways different requirements With regard to the profile of the vehicles or processes to be used in relation to a landmark-free evacuation, it is possible to dispense with the installation of additional sensor devices, advantageously, in the case of run-off operation. So it is conceivable, for example, that in the case of a maneuvering by means of routes in which optionally operators can ride laterally on the respective car or vehicle, a larger profile width is used as in the case of an automatic operation, in which a corresponding ride is excluded by operating personnel , This has the consequence that with respect to the switch a narrower profile space and thus a border-free clearing of the switch already result in complete passing of the rug point. The fact that the sensor device is used in the context of the preferred embodiment of the method, which is provided in the case of a maneuvering with driveways to clear the switch cleared as a landmark, now advantageously eliminates the need for installation of additional sensors for detecting the landmark clearing of Räumpunktes in drain operation. At the same time advantageously changes in maneuvering with routes are avoided.

In principle, the sensor device and the free-reporting point can be arranged as desired in the region of the switch. This means that either the location of the sensor device or the free-signal point can be closer to the center of the switch.

According to a further particularly preferred embodiment of the method according to the invention, a sensor device is used in the region of a branch track of the switch, wherein the location of the sensor device is farther away from the center of the switch than the free-reporting point. This is advantageous, for example, in those cases in which the relevant sensor device according to the aforementioned preferred development of the method according to the invention is used for this purpose is, in the case of a maneuvering with driveways to detect a border-clearing of the switch and can be used for the automatic operation of a roughing operation Runoff point, which is closer to the center of the switch.

In principle, a sensor device of any kind can be used in the context of the method according to the invention. What is essential here is merely that it is designed to detect the first sequence or the first axis of the first sequence. Thus, for example, by means of an optical sensor device, for example in the form of a light grid, an entry of the first sequence into an optical monitoring area can be detected.

According to a further preferred embodiment of the method according to the invention, an axle counting point is used as the sensor device. This is advantageous since axle counting points, which are also referred to as wheel sensors or rail contact, are widespread in drainage systems, especially in connection with axle counting systems, where they usually serve both for detecting the axes of the processes and for determining the speed of the processes.

According to a further particularly preferred embodiment of the method according to the invention, the first sequence is detected on the basis of its first axis. This is advantageous in particular in the case of using an axle counting point as a sensor device. In addition, in order to increase the accuracy of the method, the times of detecting the further axes of the first sequence may also be used in the sequence, if appropriate, with regard to an improved determination of the clearing time or a possible contact of the two sequences.

Preferably, the inventive method can also be developed such that the determination of the Räumzeitpunktes and / or the determination of whether it is in the case of a comparison changed to the first course, the deflecting position of the switch before the Räumzeitpunkt come to a touch of the two processes, using time-distance lines for at least the first and / or last axis of the respective process takes place. This is advantageous since the use of time-distance lines is a known, proven procedure for monitoring, forecasting and simulating processes in drainage systems.

According to a further particularly preferred embodiment of the method according to the invention, the emergency reporting point can also be used to schedule the expiration operation in such a way that the first expiry has cleared the switch border-free in relation to the fouling point, before the second expiry the switch or reached the fouling point. The forecasting or simulation of the sequence operation can take place both before the actual execution of the sequences and also completely or partially during the execution. By using the free-reporting point in the context of a corresponding prognosis or simulation, advantages may arise with regard to the drainage performance and / or the marshalling quality of the drainage system.

The invention further relates to a control device for a rangiertechnische drainage system.

With regard to the control device, the present invention has for its object to provide a control device for a rangiertechnische drain system, which is particularly efficient in terms of determining the Grenzzeichenfreiheit turnouts of drainage system particularly powerful, flexible and at the same time with comparatively little feasible method for operating a technical draining plant supported.

This object is achieved in that the control device for the technical draining plant means for performing the method and / or for carrying out the method according to one of the aforementioned preferred developments of the method according to the invention.

In the following the invention will be explained in more detail by means of exemplary embodiments. This shows

FIG. 1

in a schematic sketch, a switch of a technical draining plant and

FIG. 2

to explain an embodiment of the method according to the invention, a schematic time-path diagram for two successive processes.

FIG. 1 shows a schematic sketch of a switch a ranking technical drainage system. In detail, here a turnout 1 is shown, branch off from the two branch tracks 2 and 3. In the context of the exemplary embodiment described here, it is assumed here that the switch 1 is a diverter switch of a draining plant, processes in the form of running trolleys or groups of wagons driving the switch 1 from the pointed side, ie from left to right, so that the path of corresponding processes in the switch 1 can branch into either the track 2 or 3 in the track.

In addition, in FIG. 1 two freight cars 4, 5 or their outlines or carriage profiles indicated. It is in FIG. 1 shown the situation in which the two tracks 2 and 3 are just as close to the switch 1 zoom with the car 4, 5 occupied, that it just does not come to a touch of the two cars 4 and 5. In this case, the two tracks 2 and 3 or the switch 1 so cleared borderless or free of crosses, as in the present situation, no contact between the two cars 4 and 5 would take place. The reference numeral 6 is here in the FIG. 1 a corresponding Border mark or the track distance with border-free eviction of the switch 1 indicated.

As a result, it is now assumed within the scope of the exemplary embodiment described that a wider profile of the carriages 4, 5 is to be assumed for a shunting operation by means of routes for the determination of the limit-sign freedom. This is in FIG. 1 indicated by dashed lines and denoted by the reference numeral 4 'and 5'. For example, it may be required that, unlike a borderline clearance with a track spacing of 3.5m for the shunting a track distance of 4.0m should be recognized to account for the fact that in shunting operating personnel on the side of the car or vehicles 4 'or 5' can stop, such that a corresponding person mitfährt on a running board. It should be noted that it can be in the shunting of the car or vehicles 4 'and 5' in particular also a shunting locomotive.

Based on a correspondingly changed track spacing of, for example, 4.0 m, as shown in FIG FIG. 1 move the boundary mark 6 to the right, which is indicated by a corresponding line and designated by the reference numeral 6 '. This means that in shunt mode, the switch 1 is vacated without a mark compared to the automatic sequence operation later. For the automatic sequence operation the assumption of a correspondingly changed limit sign would have the consequence that negative effects would result. This applies in particular to the case where the switch 1 is to be placed after a first sequence with respect to a second subsequent sequence as a protective switch to avoid Aufpufferns of the two processes in repellent, ie changed, location. In order to avoid such limitations, it could now be considered, both in relation to the frontier mark 6 and in relation to the changed frontier mark, 6 'rail contacts or to provide axle counting points, in order to be able to detect a border-clear clearance of the switch 1 in both cases. However, this would be associated with considerable additional costs and expenses, which are not only due to the additional hardware required, but also on their installation and their consideration in the free field logic of the associated Rangierstellwerks.

The following is based on FIG. 2 be explained in more detail, as well as without corresponding additional axle counting the in FIG. 1 indicated situation with respect to different profile widths or different limit sign positions can be taken into account. To avoid misunderstandings, it should be emphasized at this point that the method according to the invention can also be used in other situations. Ultimately, this applies to all cases in which no sensor device for detecting the landmark-free evacuation of the switch is present at a point at the passing of which a switch is to be regarded as having been cleared of borderline mark with respect to a fouling point.

FIG. 2 to illustrate an embodiment of the method according to the invention is a schematic time-path diagram for two successive operations. In the illustrated time-path diagram is shown for two consecutive operations 10 and 20, respectively, at which time t these have traveled a distance or a distance s. In this case, the time-distance line 11 marks the course of the first axis of the first sequence 10, ie the precursor, through the drainage system. In a corresponding manner, the time-distance line for the last axis of the first sequence 10 is identified by the reference numeral 12. Furthermore, corresponding time-distance lines 21 and 22 are also shown for the first or last axis of the second, the first sequence following process 20, ie for the trailer.

To avoid misunderstandings, it should again be noted that FIG. 2 only shows a schematic representation to describe the embodiment of the method according to the invention. It should be noted in particular that the representation is not scaled and, as indicated in the abscissa axis, only a section of the path of the processes 10 and 20 shows.

For correlation of the distance traveled s with along the route arranged trackside components is also in the lower part of the FIG. 2 an example of the arrangement of a switch W in the path of the two processes 10 and 20 outlined. It can be seen here that a rail contact or axle counterpoint KWE is arranged in the form of a switch inlet contact at a position s1. This thus serves to detect a travel of the switch W. At a location marked s2 with respect to the distance covered, there are further axle counting points KWL and KWR which serve, in particular, to detect when the last axis of an operation is the track section between the axle counting points KWE and KWL or KWE and KWR has left. From this time, the switch W is due to the fact that the process has left the moving parts of the switch W, adjustable again.

According to the presentation of the FIG. 2 are arranged after a continuous distance s4 in the two branching tracks two more rail contacts or axle counting KGL and KGR, which serve in particular to detect a border-clearing of the switch W by a track traversing the respective process. The borderline freedom is characterized by a borderline GZ. This means that at the point marked by the mark GZ two processes can drive the switch W in different directions without touching each other. The achievement of the limit character freedom is detected here by the track contacts KGL or KGR, which due to the necessary consideration of buffer overhang further to the right than the boundary mark GZ are arranged.

As a result, it is assumed that the limit sign GZ and thus the arrangement of the axle counting points KGL and KGR with respect to their location or their position does not correspond to what is to be based on the automatic sequence operation of the technical waste disposal system. As explained in connection with FIG. 1 This may be caused, for example, by the fact that the limit mark GZ and the axle counting points KGL and KGR have been shifted to the right, in order to take into account an enlarged profile space of the switch W due to a larger assumed width of the operations in shunting operation. For the automatic sequence operation, however, should be based on a smaller width of the processes, which results in the problem that no Achszählpunkte are provided, which are arranged at the position that would be required in relation to the assumed width of the processes a border-clearing of the Soft W to detect. The required position of corresponding axle counting points is in FIG. 2 also indicated and labeled with the reference VGL or VGR. In the context of the exemplary embodiment described here, it is assumed here that the "virtual" free-field points or track contacts VGL and VGR are drawn at the point in which real track contacts would have to lie, in order to clear the switch point W for the sequence operation based on a corresponding Räumpunkt RP to detect.

The course of the first sequence 10 along its path will now be described below. In this context, a nomenclature of the time points is used in such a way that the first index indicates the respective sequence at the times or points in time and the second index respectively indicates whether the time point relates to the first or the last axis of the relevant sequence , The first axis of the process is specified with an index "1" and the last axis with an index "2".

At a time t ₁₁ , the first axis of the first outlet 10 reaches the waypoint s 1 and thus the switch inlet contact KWE, corresponding to the time-distance line 11. As a result, the switch W is detected as busy, ie a changeover of the switch W is now no longer possible. At a later time t1 ₁₂ then reached according to the time-distance line 12 and the last axis of the first sequence 10 the points inlet contact KWE. In its further run, the first sequence 10 in the sequence passes the waypoint s2, wherein the first axis reaches this at the time t2 ₁₁ and the second axis at the time t2 ₁₂ .

In the context of the exemplary embodiment described, it is assumed that the switch W is set to the left, so that the first run 10 passes the left switch contact KWL at the waypoint s2. At the time t2 ₁₂ , the last axis of the first sequence 10 has also passed the waypoint s2. This is detected on the basis of a comparison of the axes counted by the switch inlet contact KWE and the left switch contact KWL, whereupon the switch W is now again adjustable.

As a result, reaches the first axis of the first flow 10 at the waypoint s4 at time t4 ₁₁ the points outlet contact KGL of the left track. The points outlet contact KGL is now used as part of the described embodiment of the method according to the invention as disposed in the region of the branching switch sensor means KGL for detecting the first flow 10 and its first axis.

From a sequence control of the drainage system, taking into account at least the location of the sensor device KGL and the time t4 ₁₁ of detecting the first process 10, a clearing time t3 _{12 is} determined or predicted, to which the first cycle 10 the from the location of the Sensor means KGL deviating free reporting point VGL completely happened and thus the switch W will have vacated border-free with respect to the Räumpunkt RP. As already explained, it is hereby assumed that the first run 10 will have cleared the switch W relative to the clearing point RP without a border when its last axis has reached the waypoint s3, ie the "virtual" free-mark point. The corresponding coordinate point s3, t3 ₁₂ is in the FIG. 2 clearly marked. It should be noted that the location of the Räumpunktes RP as shown in FIG. 2 due to the necessary consideration of buffer overhangs does not coincide with the position s3 of the (virtual) read-only point VGL, again taking into account that it is FIG. 2 is not a true scale representation.

Like in the FIG. 2 illustrated by a corresponding triangle, is the first flow 10 starting from the time t1 ₁₁ to the time t3 ₁₂ with respect to the Räumpunkt RP landmark-free eviction in the area of the switch W. For the subsequent second flow 20, which is also a can run individual wagon running or a running group of wagons, it can now be determined whether it is likely in the case of a changed compared to the first sequence 10 repellent position of the switch W before the Räumzeitpunkt t3 ₁₂ to touch the two processes 10, 20 or would.

Relative to the second drain 20 is in FIG. 2 It can be seen that the latter will reach the waypoint s1 with its first axis at time t1 ₂₁ and with its last axis at time t1 ₂₂ . It is more important, however, that the second run 20 will not touch the first run 10 until the clearance time t3 ₁₂ . This is recognizable by the fact that no overlaps of the time-distance lines 21, 22 of the second sequence 20 with the time-distance lines 11, 12 of the first sequence 10 result up to the time of evacuation t3 ₁₂ even taking account of buffer overhangs. In addition, it is also recognizable that the second sequence 20 for the clearance time t3 ₁₂ or at the time t2 ₁₂ , to which the switch 1 is again adjustable, the switch inlet contact KWL has not yet reached and thus the adjustability of the switch W is not affected or impaired.

As already explained, it can be seen from the time-distance line 21 that the first axis of the second sequence 20 marks the waypoint s3, which marks a landmark-free clearing of the switch W by the last axis of the first run 10, only at a time t3 ₂₁ achieved (compare the in FIG. 2 clearly emphasized point s3, t3 ₂₁ ), whereby a touch of the two processes 10, 20 is excluded over the entire path to behind the switch W. If, for example, due to an unexpectedly poor flow behavior of the first sequence 10, the switch 1 should be provided as a protective switch to prevent buffering of the two processes 10, 20, this can be done safely according to the above statements. Thus, the switch W, which is also adjustable as already stated, be converted to the repellent position, so that the trailer is directed in the form of the process 20 in the right-hand branching track and thus a buffering is avoided.

It should be noted that a corresponding changeover of the switch W in the protective position would not be possible in the event that the sensor device KGL itself would be used to detect the landmark-free evacuation of the switch 1. So is in FIG. 2 It can be seen that the last axis of the first sequence 10 reaches the associated waypoint s4 only at a point in time which essentially corresponds to the time t4 ₂₁ at which the first axis of the second sequence 20 also reaches the waypoint s4. This is in FIG. 2 also marked by a highlighted point and indicates that a use of the switch W as a protective switch in the present case is made possible only by the fact that instead of the boundary mark GZ as the reference point of the landmark-free eviction the switch W Räumpunkt RP is used to which the free-reporting point VGL is assigned.

In the event that the switch W has already been placed in a repellent position, this position is maintained as a result of the method, since it is ensured that there will be no contact between the two processes 10 and 20.

If, as a result of the investigation, it is shown that the deflecting position of the switch W would presumably lead to a contact of the two outlets 10, 20, the switch W advantageously remains in a position which is unchanged compared to the first outlet 10 or becomes in the case of its adjustability in the event that it had previously been placed in a dismissive position, returned to this unchanged situation.

In accordance with the above explanations, the method can be triggered, in particular, by recognizing, within the framework of monitoring the operation of the drainage system, that the first run 10 is being retrieved by the second run due to an abnormal runoff behavior of the first run 10 and / or the second run 20 threatens.

Advantageously, the forecasting or determination of the clearing time and / or the location of the second run 20 takes place at the time of broaching with further consideration of at least one characteristic variable specific to the respective run 10, 20. In the case of corresponding parameters which are specific for the respective sequence 10, 20, these may in particular be variables determined in the course of the sequence operation and / or provided by a scheduling system. This includes, in particular, the length of the respective run 10, 20, a buffer overhang of the respective run 10, 20, the weight of the respective run 10, 20, the running resistance of the respective run 10, 20, the current and / or future speed of the respective run 10 , 20, the current and / or future acceleration of the process 10, 20 and the current and / or future rolling resistance of the respective sequence 10, 20. Thus, processes, such as when entering the distribution zone, usually measured at least in terms of their length and weight.

Due to the continuous observation of the speed behavior of the processes during their running and further use of rolling and running resistance values, which are also usually determined in the course of the operation, the acceleration or the running behavior of the processes or wagons can be calculated or predicted with high accuracy. Thus, in accordance with the explanations related to FIG. 2 be determined using predicted time-distance lines 11, 12, 21, 22 of the respective processes 10, 20, and if so, at what time the processes 10, 20 meet at the switch W and whether this with respect to the Räumpunkt RP provides border-free protection. In this case, the reference to the Räumpunkt RP landmark clearing of the switch W is not detected directly by a sensor device, such as in the form of a Achszählpunktes. Instead, in the context of the method according to the invention, as part of a prognosis, a clearing time is determined which is characterized by complete passing of the virtual clearing point VGL assigned to the roughing point RP.

It should be noted that possibly also the track contacts KWL or KWR or u.U. even the turnout contact KWE could be used as a sensor device for detecting the first process 10 as a basis for the forecasting of the clearing time. In addition, within the scope of the method, of course, types of sensor devices deviating from axle counting points can also be used.

The free-reporting point VGL can advantageously also be used, if appropriate, to plan the sequence operation in advance in the context of a prognosis or simulation in such a way that the first drain 10 has cleared the switch W with respect to the fouling point RP in a manner that is free of markers before the second drain 20 reaches the switch W or the fouling point RP.

A control device for a technical draining system, which has means for carrying out the method described above, will generally have both hardware and software components. In addition to the sensor device, this relates in particular to a corresponding control computer with associated programs for controlling the sequence operation.

According to the above explanations in connection with the described exemplary embodiments of the method according to the invention and the control device according to the invention, these have the particular advantage that a determination or prognosis of a clearing time to which a run completely passes a roughing point RP and thus the relevant switch with respect to the roughing point RP has been vacated without a border-mark, in a particularly flexible and efficient way. Depending on the particular circumstances, it is possible, in particular, to save any additional sensor devices that are otherwise required, for example in the form of rail contacts.
