Abstract

In a method for controlling the sequence of the wagons of a railway train to be dismantled from a discharge hill of a marshalling yard into the distribution zone of the marshalling yard, the wagons from the distribution zone are distributed to different target tracks by means of successive separating switches. The control of the release signal for the sequence and the switches for the route of a car (trailer) takes place in such a way that a collision of the trailer with a rotating switch and a harmful collision of the trailer with the predecessor is excluded. For this purpose, the release signal for the sequence and / or the points for the travel path of the follower are controlled as a function of the dynamic behavior of the predecessor. The dynamic behavior of the forerunner can be determined during its run and then the run of the backer can be controlled. A prediction of the dynamic behavior of the predecessor and storage of the blocked lengths determined afterwards is also possible.

Description

The invention relates to a method to control the sequence of the wagons of a railway train to be dismantled from a run-off mountain of a marshalling yard according to the generic term of claim 1.

Such known system serve to distribute the wagons of a train to other trains. The Routes of the running wagons (processes) on different Target tracks collected and trains to be put together, are by switches (separating switches) given and differentiated from each other. One moves Abdrücklokomotive the train to be dismantled (the dismantling unit) at low speed to the drain mountain. When displaying the trigger signal with z. B. white light (Release) the moving on goes the disassembly unit in the pressing process. Doing so the first wagon on the mountain uncoupled and pushed over the mountain top. On the slope behind the hilltop the running wagon (process, forerunner, follower) is accelerated and the trigger signal set to red by driving on contacts (mountain contacts).

The release for the next process (successor) is by switching the trigger signal to z. B. Displayed in white. So far, this switchover has only taken place when the first sequence (Forerunner) Has reached the target track and determines the route of the trailer Switches have circulated. In this way, is between on each other following procedures a safety margin is maintained to ensure that the precursor following, coming soon abzudrückende Wagon (trailer) neither with the precursor still collided with a rotating switch. As a lock length in the known methods the length between the drain mountain or the follow-up waiting for it and the output of the separating switch which the precursor has to drive to reach its target track. The release the expiry of the follower So it only happens when everyone the route of the forerunner determining switches in the determining the route of the trailer Position has circulated. For automatic activation of the release signal the separating switches are therefore provided with sensors at their output, which is the extension of a car, i.e. of the forerunner, from the turnout area capture (exit sensors). Through the exit sensor of the separating switch of the predecessor the release signal of the follower is triggered.

This ensures that the forerunner Distribution zone completely has left and that the Drainage path for the next Waggon (process) is safe. The process will only be activated after this release uncoupled and pulled. If two processes for the same Directional track are determined, the release for the process takes place of the follower only when the forerunner the last switch system (separating switch), which the route in the determined, cleared the common finish track. A catch up and so-called Buffering the back-up on the forerunner is not to be avoided completely and is even desirable if the speed difference is none damage can be expected.

The disadvantage of this method is in that the Drainage performance is quite low because there are never several cars at the same time the same track in a row, i.e. drive into the distribution zone. This Disadvantage is exacerbated by that when dismantling a train with well running wagons (Gutlaufers) and poorly running wagons (bad runners) must be expected. Therefore can the trigger locomotive do not drive at any speed. Rather, it must at a very slow speed or even in stop-and-go operation drive. A limiting the maneuvering speed and maneuvering performance The factor is also the length of the wagons and above all the distance between the relevant ones Separation switches from the summit of the drain mountain.

It has also been considered the pulling process to carry out with uninterrupted driving and thereby the speed by means of to vary an arrow signal. However, it turned out that no increase in performance can be achieved.

The object of the invention is that capacity to increase such a switching system and without impairment security, the process and distribution of a large number of wagons per time unit. The so-called corner kick where the carriage of a wagon with the switch tongue in circulation collides, should be prevented.

The solution arises from claim 1.

While so far the presence sensor triggers the release signal that the exit of the forerunner in that for certain target track grips him, the lock length So always the distance between the respective exit sensor of the Target track and the drain mountain, the blocking lengths are now variable dependent on determined by the dynamic behavior of the wagons. This can achieved a much denser sequence of processes and the process of the follower can already be released if the precursor is still in the distribution zone is located, i.e.: the separating switch to its target track has not yet been reached, at least not yet left.

This can shorten the safety distances can be achieved without loss of security.

In particular, it becomes possible to use dynamic process criteria in different ways, ie different criteria in different extraction and processing and for different functions. This lets you see through flexible match the dynamics of the processes to achieve a tight wagon sequence.

This is in contrast to the previous rigid Handling in which only one criterion (freedom of Distribution zone) to a single function, namely the release of the subsequent process for the next Wagon (trailer) is being used. He wishes is to achieve this aim of the invention with simple means i.e. without additional to achieve equipment of the drainage mountain and the distribution zone.

This is done through training according to claim 2.

One takes advantage of the fact that the destinations in principle are known and that the The running behavior of the individual wagons depends on the weight, Furthermore but only fluctuates within known limits. By considering the expected influencing factors of the Process behavior of the individual processes from the process mountain and in the distribution zone to the individual dividers or target tracks and laying down these influencing factors consideration an inaccuracy factor in an electronic memory the process is controlled. In particular, the profile of the drain mountain by height and inclination as well as the length the respective distribution route is taken into account. (Claim 3).

To this extent, the embodiment of the invention must be guaranteed be that dynamic behavior of the process by a suitable for automatic control Characteristic represents becomes. This happens both in the design of the ending Claim 2 as well as in that according to claim 12, namely by that the Lock length not more geographically but in line with dynamic behavior every expiry for Each target track is determined and assigned to the target track and saved will (claim 4).

By the design according to claim 5, 9 and 10 ensures that there is no collision of the follower can come with a rotating switch.

To adapt the ending to the special one The geographical design of the distribution zone serves the design according to claim 6 to 8 As a safety margin is the Distance between the drain mountain and one of the switches chosen preferably before the separating switch of the precursor.

This sometimes leads to the fact that because of the Location of the turnouts the blocked lengths longer chosen Need to become than required by the dynamic behavior. This disadvantageous Effect is prevented or mitigated in the design of these claims, by including switches in the security strategy, that do not determine the route, the dynamically required barrier length however, correspond optimally or better.

In which the process and in particular A computer module that stores the release signal is stored, in which the individual blocking lengths depending on the approachable leading into the respective target tracks Separation switches are saved and can be called up. (Claim 11)

Basically, railway operations the buffering of forerunners and followers, i.e. the opening of the follower on the forerunner accepted or even desired, if no harm of freight or wagon is to be expected.

However, it is after another Development of the invention also possible even with extreme bad runners very short blocking lengths to achieve and still a corner kick or a damaging To prevent buffering.

This is done according to claim 12 a speed measurement using a speed sensor or several fixed speed sensors. Through this training The ending is a further relaxation of the expiry date in the sense a shortening the safety distances and the increase the drain frequency reached.

The method according to the invention has the advantage in particular of increasing the performance of the drainage system, if from a forerunner Separation switches further away must be approached. The barrier length is even shorter than in this case the distance between the drain mountain and the separating switch that the Trailing has to start, preferably plus the distance between the separating switch and the outlet of this separating switch. Through this variable, i.e. individual specification of the blocking length ensured that none Collision of the trailer in the for him or the forerunner Switching switches to be switched, especially no corner impact with the Soft, done. Dependent the distance between the drain mountain and the individual separating switches can now the lock length defined as the distance between the drain mountain and the forerunner which one for the from the follower separating switch to be approached is necessary. This lock length is consequently shorter dimensioned than before.

The safety distance is therefore also in this version dependent on from the profile of the mountain (altitude, Inclination) and other dynamic factors such as weight in particular for each Process and each target track variably specified. No later than the axle counter, which detects the exit of the last axis of the forerunner at the end of the blocked length (in this registration as the "free -running -axis counter "), signals also the speed of the forerunner and triggers depending on this speed a signal that either blocks the release or the Protective switch program triggered becomes. In the latter case, the dodge or all of it is located in front of the dodge Switched switch.

According to claims 13 to 16 is a Measuring point selected so that on the one hand it ensures the necessary safety of the sequence operation, on the other hand it allows optimally short safety distances.

Through the following training courses an adaptation to the respective desired function and the respective geographical conditions of the drain mountain, the distribution zone and the respective separating switches and finish tracks.

Claims 13 and 14 serve typically the purpose of triggering the release and / or a protective switch program.

The closer the distance to the measuring point because of the separating switch, the more suitable it is the signal for the To give approval. Execution guaranteed according to claim 14, that the release dependent on from the detected speed and without disturbing the Can occur due to unforeseen events. claim 14 typically serves the purpose of avoiding buffering in the target track, when an extremely bad predecessor is chased by a follower, which is headed to the same target track.

Claim 15 enables the release of the wake dependent only from the detected speeds and the shortening of the Safety distance on the distance between the summit and the dodge.

Claim 16 permits an extreme shortening of the Safety distance.

The concept of avoidance becomes referred to the definition of claim 7 and 8.

The further problem arises that 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 largely prevented. Because each target track has a measuring point for the dynamic Properties of the process are assigned, the dynamic properties, that result from the finish track, in particular the one still to be covered Running route and its gradient, by choosing the location of the measuring point be taken into account.

On the other hand, the position of the measuring point must also take the security requirements into account. This happens after Claim 18 in that a Minimum distance is determined, which is determined from the empirically determined dynamic properties of worst and best processes.

The problem arises, suitable evaluations of the measured speed signal to find one after Frequency and security to enable optimal operation.

This happens through the advanced training Claims 19 to 22.

With a single measurement results a meaningful one Control signal by comparing the actual signal with a stored one Target signal compared and the appropriate process strategy based on the result (Release of the process, specification of the blocking length, protective switch program) is specified. (Claim 20)

With a measurement at the beginning and on End of the blocking section is a speed comparison of forerunner and Trailing possible (Claim 20), again with the preferred embodiment that the distance between the summit of the drain mountain and the measuring point according to the expected dynamics of the process can be specified, namely: Thereby has the measuring point at the beginning of the blocked length a distance according to claim 18 and the dimension point at the end of the blocking length a distance from the separating switch or - if a protective switch program triggered should be - from the next Dodge that ensures that too the fastest successor the slowest precursor in the remaining stretch between the end of the restricted stretch and the separating switch or diverter cannot catch up.

An individual conforming to reality The dynamic properties of a lead can be determined by two successive sensors, each of which is the speed of the predecessor signal so that the Loss of speed in the known route between the two dimension points can be determined. By comparison with a still permissible setpoint or by calculating the further speed curve can then be determined whether the release takes place, a certain blocking length is specified or a protective switch program is to be triggered.

The evaluation of the signals according to claim 22 contributes to Uniqueness of the measurement results and control signals.

Furthermore, the invention makes itself to the task, suitable strategies for controlling the sequence operation to disposal to ask what the special opportunities that arise from the Invention according to claim 1 and 12 result, use.

In the event of an impermissible measurement result or its refurbishment can - how said - the Release of the follower blocked (claim 23) and / or - if the release already is done - a so-called protective switch program (claim 28) triggered and / or the lock length individually for the affected precursor be fixed.

The protective switch program includes that one or more or all Points are changed, which are e.g. lie in front of a certain switch. In this way it is achieved that at 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 corner kick.

• – wenn in einer Weiche durch ein Fahrzeug eine Störung zu erwarten ist, wenn also durch die dort angebrachten Fahrzeugsensoren, z. B. Achszähler die Weiche als belegt gemeldet ist,
• – wenn eine Weiche ihre Endlage sieht erreicht; in diesem Falle läuft die Weiche wieder zurück; es wird jedoch schon vorher das Schutzprogramm ausgelöst, wenn der dort angebrachte Weichen-Lagemelder nach der normalen Laufzeit signalisiert, daß die Weiche ihre Endlage nicht erreicht hat.

The protective switch program has so far only been triggered,

• - if in a switch by a vehicle A disturbance is to be expected if the vehicle sensors attached there, e.g. B. axle counter the switch is reported as occupied,
• - When a switch sees its end position; in this case the switch runs back; However, the protection program is triggered beforehand when the turnout position indicator attached there signals after the normal runtime that the turnout has not reached its end position.

The protective switch program is made according to the invention in the process strategy to shorten the barrier lengths included. In particular, the protective switch program is also in this embodiment fires to prevent buffering on a bad runner. One has in this case a stranger, however avoids the damage on vehicles or cargo.

Suitable protective switch programs result from the claim 29, which aim to shorten the To achieve safety distance in that, if necessary, the forerunner or the follower is redirected to another than its target track.

Another increase in drainage performance too with big Distance of the running properties to be taken into account is achieved according to claims 24 to 27. If dependent from the measurement signal a lock length individually for the predecessor concerned is, (claim 24), one reaches an optimally short blocking length under consideration all security issues. This makes it possible, even when uncovering of bad runners not block the distribution zone absolutely but the next process adapting to the peculiarities of the distribution zone and the dynamics of the forerunner like this soon as possible release.

For this, however, the position of the measuring point must be or - at a measurement of the speed difference at two measuring points - the location of the second measuring point considering selected from claim 18 become. In this embodiment of the method are also other strategies mentioned apply. The release signal takes place then by a presence sensor, which a predetermined Position at the end of the blocked length has and preferably positioned according to claims 9 and 10 is.

Suitable presence sensors and speed sensors are available, for example in the form of double electromagnetic sensors DE-C1 43 25 406 (Tig 9201). These are also used as presence sensors, in particular as limit sensors, ie: input sensors and output sensors (free-moving sensors) of each turnout, which report the assignment of the turnout by detecting the entering axes and the extending axes. These sensors can also serve as speed sensors, so that further equipment in the distribution zone is not required. It is therefore only essential that the measurement signals of which of the available 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 has left the sensor's sphere of influence. It can be z. B. are inductive wheel counters, which are arranged on the rail. The individual blocking lengths are dimensioned in such a way that, on the one hand, it is ensured that even badly running forerunners have safely left the isolation switch to be switched for the trailer before the release signal and thus the switch for the trailer to be switched is triggered. On the other hand, the blocking length is shortened in such a way that the push-off speed of the push-off locomotive can be increased and the number of wagons distributed can be increased.

In the following, embodiments of the Invention described. Show it:

1 : a drainage system with control according to the stored dynamic values of the drainage

2 to 4 : Operating situations on a drain system with control according to the currently measured dynamic values of the drain

5 the determination of the measuring point in the drain system after 2 to 4

6 to 9 : further operating situations on a drain system with control according to the currently measured dynamic values of the drain

In 1 is a schematic of a drain system with a drain mountain 1 shown where a train is waiting to be dismantled. A car, the forerunner 2 has already entered the distribution zone. The distribution zone consists of a large number of target tracks 13 . 15 , each of which can be accessed via a separating switch. Here are only two finish tracks with dividers 3 and 8th shown.

The forerunner has the switch 8th drive through to in his divider 3 on the target track 13 to be directed. The next car 7 , the follower, can only be pressed when the release signal 12 is released accordingly.

The switches are through sensors 4 . 5 . 6 and 9 . 10 . 11 secured. These are axle counters, which emit a signal in the presence of a railway wheel. These are two inductive sensors, so that the direction of movement and the speed of the passing wheel and wagons can be determined from the sequence of the signals. The input sensors 4 respectively. 9 count the wheels entering the turnout area. The output sensors 5 and 6 respectively. 10 and 11 count the wheels moving out of the turnout area. The output sensors 5 and 6 respectively. 10 and 11 release the turnout to a turnout drive, not shown, if the number of one moving corresponds to the number of extending wheels. For this purpose, the sensors with the computer 14 connected.

Between the input sensors 4 respectively. 9 and the output sensors 5 and 6 respectively. 10 and 11 are the limit signs, not shown, of the respective switch.

In the computer shown 14 , which is the release signal 12 controls, a program is entered which is activated when the separating switch is activated 3 the switch for the forerunner 8th as a dodge for the follower.

Because the forerunner 2 the output sensor 10 the dodge 8th has run over, they are caused by the sensor 9 axes counted in the computer again, so that the sensor 10 now releases the turnout drive and at the same time signals to the computer that the precursor is the area of the turnout 8th happened.

Now the computer gives the release signal for the follower. If through the output sensor 10 but it was also found that the forerunner is a bad runner, ie that the speed is below a target speed previously determined for this point, this sensor continues to trigger the protective switch program. The switch is made 8th so that the trailer only in the finish line 15 can drive. If the trailer is not intended for the target track, the switch is switched again beforehand. If between the drain mountain and the dodge 8th If there are still other switches, the protective switch program can switch these switches cumulatively or alternatively, so that a buffering of the back-up to the forerunner is avoided in any case.

It is preferred that all switches Boundary sign - free are; d. h .: the limit signs of the switch lie between the sensors (Axle counters), which signal the presence of a vehicle in the area of the switch and when entering and exiting (clearing) the separating switch give a signal. The boundary signs indicate the minimum distance between the buffers from the point of intersection of the switches, so that vehicles on the occupied route without touch can happen.

At the time T ₀ , a wagon (forerunner V) is released from the summit. This starts with a certain acceleration (in addition to its existing speed / pulling speed). In the 2 to 4 Different operating situations of the same system are shown, in which only a speed measurement of the predecessor takes place. The speed of the precursor is determined at the measuring point M. The speed curve of the forerunner can be determined on the basis of this measured value on the basis of empirical values which are fed into the control computer of the system. This assumed speed curve of the predecessor is with a line 16 displayed.

Depending on the speed signal will be the next Process (successor) controlled.

A reference is made to the stored permitted speed of the worst run (worst runner). This speed curve of the worst runner is with a line 18 shown in dash-dotted lines.

The acceleration of the process and the speed curve of the follower in the distribution zone is stored in the computer, using a so-called "best runner" as a model. The best runner is a wagon which has the best run-off properties occurring on the drain mountain minus a safety discount. This speed curve is with line 17 displayed. The distance A between the front buffers of the follower and the rear buffers of the predecessor can be seen on a horizontal axis at all times.

In the operating situation after 2 arises at the measuring point M, that the speed of the precursor is greater than that of the Worst of the rotor, so that at the measuring point in relation to the adopted test rotor Schlech a time t _{prior to} projection. results. This time advantage of the predecessor before the worst runner is in the situation after 2 bigger, in the situation after 3 is smaller than the approved safety time lead t _{S - before} the predecessor before the worst runner. Therefore, there is a different process control:
In the operating situation after 2 the process of the back-up is released. The distance A remains up to the entrance of the precursor into its diverging points WT = 3 is greater than the smallest permitted safety distance A _is.

The approach of the follower to the predecessor is accepted, because there is still an off before the separating switch WT of the predecessor soft WA 8th is to which the follower can be redirected if the further speed course of the forerunner or follower turns out to be less favorable than assumed. In the operating situation after 3 the process of the back-up is not released. The distance A would to the entrance of the precursor into its diverging points WT small as the smallest permitted safety distance A _itself.

It is possible to trigger a protective switch program, through which the follower or the forerunner would be redirected to a switch AW = 8 located in front of the separating switch WT. Under these circumstances, however, the procedure described below would be followed 4 apply.

In the situation after 4 the forerunner arrived at the measuring point later than the assumed worst runner. Therefore, the sequence of the back-up is now not released, but a blocking length A _{blocking is} defined. This means that a point is set at a distance A from the measuring point, at which a presence _{sensor detects} the presence of the precursor. In the case shown, it is the input sensor of the diverter WA, which is located in front of the separation diverter. This ensures, on the one hand, that there is always a sufficient distance between the processes and, on the other hand, that the follower can, if necessary, be diverted to the diversion as part of a protective switch program. It is then an erroneous stranger, provided that the diverter is not identical to the separating diverter of the follower.

• – die Durchschnittsgeschwindigkeit eines Ablaufs,
• – die Abweichung von einer vorgegebenen Durchschnittsgeschwindigkeit z.B. des Schlechtestläufers,
• – bei zwei Zeitmessungen in zwei Strecken bekannter Länge auch der Geschwindigkeitsverlust und die Abweichung des Geschwindigkeitsverlust von demjenigen des z.B. Schlechtestläufers ermittelt werden.

It follows from the above that the speed measurement can also be carried out as a time measurement between two points with a known distance. This can be used, for example

• - the average speed of a process,
• The deviation from a predetermined average speed, for example of the worst runner,
• - With two time measurements in two distances of known length, the speed loss and the deviation of the speed loss from that of the worst runner, for example, are also determined.

5 shows the same distribution zone in the diagram as before with the determination of the position of the measuring point M. The theoretically assumed, empirically determined driving curve is shown 18 of the worst runner and the driving curve, also empirically determined 19 of the runner. The dimension point must be placed in terms of its distance from the summit G so that when the worst runner is released by a worst runner when he passes the measuring point, the worst runner reaches his separating switch or - as shown here - in any case reaches the specified avoidance WA without buffering of the back-up or an impermissible approach with risk of cornering in the switch or the separating switch. In the case shown, the implementation of a protective switch program to achieve the diversion is selected as a criterion for the position of the measuring point.

In the 6 to 9 Different operating situations of the same system are shown, in which two speed measurements of the predecessor take place.

The speed is determined at the dimension points M ₁ and M ₂ . The measuring points M1 and M2 have a predetermined distance A _{M / 1-2} .

The measuring points are - as before with reference to 5 described - determined, but placed in an area of the distribution zone in which an acceleration of the processes can no longer be expected, especially in the zone without gradient.

The speed course of the drains can based on these measurements based on empirical values that are fed into the control computer of the system are determined. It should be noted that even with this method the speed itself, measured at one of the measuring points - as before described - for Control of the release, a protective switch program or for definition a lock length can be used. In particular, based on such a measured value be determined whether the measured absolute value of the speed it can be expected that the precursor will reach its target track and / or whether it is in the same target track catch-up followers the forerunner with inadmissible drive up (buffer) at high speed.

In the operating case after 6 depending on the speed loss of the forerunner, the process of the backer is released. The predicted speed curve of the predecessor is with a line 16 displayed. For example, the speed loss of the predecessor in the distance A _M can be compared as a practical measurement variable, calculation variable and control variable with the corresponding speed loss of the worst runner, which was previously determined empirically and stored. The speed curve of the worst runner is shown in dashed lines and designated 18. Because of the low speed, it is expedient to define the difference in squares or higher powers of the measured speeds or a power of the speed loss as the speed loss.

Depending on the detected Loss of speed and the comparison with that determined for the worst runner and stored speed loss will release in particular the next Expiry controlled.

The acceleration of the process and the Ge The speed curve of the trailer in the distribution zone is stored in the computer, using a so-called “best runner” as a model. The best runner is a wagon that has the best run-off properties occurring on the discharge hill minus a safety discount. This speed curve is in line 19 displayed. The distance A between the front buffers of the follower and the rear buffers of the predecessor can be seen on a horizontal axis at all times.

In the operating situation after 6 it is found in measuring point M ₂ that the speed of the forerunner is greater and the speed loss t _{2-real is} smaller than the corresponding values of the worst runner, each including an approved safety margin.

The process of the back-up is therefore released. The distance A remains up to the entrance of the precursor into its diverging points WT greater than the smallest permitted safety distance A _is.

The approach of the follower to the forerunner is accepted, since there is a diverter WA in front of the separating switch WT of the forerunner, to which the follower can be diverted if the further speed curve of the forerunner or follower turns out to be less favorable than assumed. In the operating situation after 7 the flow of the follower is released, as was previously the case with regard to 2 to 4 has been described. The measuring point M1 serves to determine the speed advantage. In the operating case shown, however, the predecessor's runtime behavior deteriorates in an unforeseen manner. The distance A would until the entrance of the precursor into its diverging points WT smaller than the smallest permitted safety distance A _is. It is only possible to trigger a protective switch program by which the follower or the forerunner would be redirected to a switch AW located in front of the separating switch WT. For this purpose, the measurement of the speed loss at the second measuring point M _{2 is} used. By measuring the speed loss, the deterioration of the run behavior is indicated. The protective switch program can therefore be started and the follower can be redirected to the diversion WA without the safety distance A between the processes falling below the predetermined level.

In the situation after 6 or 7 it is also possible to check the dynamic behavior of the follower at one or both measuring points M1 / M2. This happens anyway to control the sequence that follows it. However, the values can also be used to determine whether a protective switch program is to be triggered by comparing the speeds or the speed losses against the corresponding stored target values of a best runner or against the previously measured actual values of the predecessor, in order to avoid buffering or a corner impact.

It should be mentioned that, depending on the speed loss of the forerunner determined, instead of releasing the follower, a blocking length A _blocking can also be defined, as is shown in 8th is shown. This means that a point is set at a distance A from the second measuring point, at which a presence _{sensor detects} the presence of the precursor. In the case shown, it is the input sensor of the diverter WA, which is located in front of the separation diverter. This ensures, on the one hand, that there is always a sufficient distance between the processes and, on the other hand, that the follower can, if necessary, be diverted to the diversion as part of a protective switch program. It is then an erroneous one, provided that the diverter is not identical to the separating diverter of the follower.

It should be mentioned again that the speed measurement also as a time measurement between two points with a known distance be carried out can. So at the measuring point M1 the elapsed time from the summit to the measuring point M1 and at the measuring point M2 the running time between the measuring points measured and from this the respective speed can be measured.

The transit time measurement also enables a method which is based on 9 is described.

A will be in the distribution zone Lock length set, either rigid or depending on the dynamic Behavior - like previously described - des Precursor.

If the blocking length is fixed, this is done the release of the process of the follower only when by the Control computer ensures that the speed of the predecessor the remaining time determined until the end of the closed road is shorter, than the runtime of a runner-up until the beginning of the closed section.

The lock length depends on the time lead or predefined by the speed of the forerunner, an additional Adjusting their length to the running properties of the precursor.

It should be noted that in this application it is assumed that a sequence, a forerunner and a successor always concern only one wagon. However, one run, forerunner and successor can also be several coupled or separate wagons, which are essentially pushed together by the run-off mountain and move to the same target track. In this case, it is of particular importance that the length of these units is also taken into account in the safety analysis and in particular the safety distance between two processes, ie forerunners and followers, which are regarded as a unit in this sense is pulled. It is therefore important that the presence of such a unit in a danger zone is usually determined by detecting the first wheel set, and leaving the danger zone by detecting the last wheel set.

It can be seen that the different Forms of presentation (presence, speed, delay, Duration) of the dynamic behavior, the various forms of Determination (storage and retrieval of empirical values, measurement, calculation) and combined the process strategies to be derived in a variety of ways can be.
