Description

Device for determining false sleepers in drainage systems The invention relates to a device for determining false runs in drainage systems with automatic Point control for the running departments by order tapes for using the switch position indicators of sequence orders from Axle counting devices for track vacancy detection of those equipped with pulse generators Switch zones.

During operation in hangar stations with automatic interlockings So-called S failures can arise due to various causes, which the Significantly affect the performance of the system. For the development of wrong walkers there are several causes. For example, the distance between two consecutive expiring wagons or groups of wagons, called departments for short, for different Directional tracks are determined, shorten so far that a turnout effective zone of the The following department is already occupied before the one through this switch operating zone limited turnout area has been cleared by the preceding department. In In this case, the turnout concerned can no longer be used for the following department be changed. As a result, the subsequent department does not get into it assigned direction track, but into that assigned to the department in front. The prerequisite for this is, of course, that the two divisions have different directional tracks were intended.

In addition, it must be expected that turnouts for other reasons, e.g. as a result of malfunctions in the drive, failure of the drive control or as a result of a block, do not get into the position specified by the sequence order can The number of wrongly running departments should however remain as low as possible, uni the operating staff should be independent Wrong-way messages and - displays are made aware of errors in this regard, so that an overview is provided is created via the additionally required maneuvering movements.

Devices for wrong run detection in automatic drainage stations are known from the magazine SIGNAL UND DRAHT 1961, issue 8, pages 120 - 125 and from booklet 9, pages 141-148. Furthermore, there is a device for determining of case runners in process systems with automatic switch control by setting order memory and track monitoring of the active zones of the points using axle counters from the DBP 1,178,888 known.

In this device switching means are provided, which the number of the axes passing through the effective zone of a switch between two clear messages Compare with the number of axles reported for the stored positioning order and at Detecting a difference will trigger the message "Wrong runner" as well as the for the Delete the wrong runner saved positioning order.

The disadvantage of this device is that it is only such wrong runner can be determined by obtaining a preceding department with arise from another running goal.

To detect false followers, for example as a result of a failure If the turnout is run around, additional facilities must be created.

Another disadvantage of the known device for determining Wrong walkers based on the fact that they show when two departments run with too little distance and thus the placement for the second department a switch must be prevented, results from the associated deletion of Process order of the second department at a time takes place on which for the first time a switch behind the first department no longer occurs is released. At this point in time, the department declared as wrong-way Prevented her from reaching her predetermined running goal while she was still on the right path and there is a possibility that the distance between the two departments, for example by means of external influencing Rail brakes enlarged again.

The invention is based on the object of avoiding these disadvantages and to create a facility which, without exception, catches palso runners, indifferent, the reason why the department in question has become a runner.

According to the invention this object is achieved in that at least an exit direction indicator is assigned to a counting pulse generator for each turnout effective zone which is a directional identifier when clearing the relevant turnout effective zone by a department emits characters, and a comparator is provided that the direction indicator with the switch position identifier stored for the switch in question Department compares and triggers a wrong-way indicator if they do not match. In this way, premature false rotor determinations are avoided in an advantageous manner. The application of this inventive concept is both in process control boxes with a Staggered switching as well as in the case of interlockings with a working memory carry out a central program control.

A preferred embodiment is characterized in that that to initiate control processes for the comparison of the direction indicator with the point position indicator when clearing the relevant effective zone an exit message memory and to initiate number of axles comparisons between one through the corresponding one Axle counting device after moving clear of the active zone, the actual number of axles and the target number of axles of all departments involved in this clearing as well as each for simultaneous triggering of the comparison of the direction indicator with the turnout location indicator these departments have a free message memory that can be queried by a central control device are provided.

This device allows in an advantageous manner already when driving of the selection points of the turnout effective zones to determine whether the department is still in accordance with the program expires or as a result of wrong switch setting or other circumstances to the wrong traveler became.

Furthermore, in a final test process after moving clear the relevant turnout effective zone, taking into account the direction of travel, whether only one or possibly other departments in the same direction are wrong or proceed properly.

The invention is described below on the basis of an exemplary embodiment for an interlocking with central information processing and a working memory explained in more detail with reference to the drawing.

The drawing shows in the upper part a section from a behind A distribution zone following a discharge mountain with three switches 1, 2 and 3. In the switch area pulse transmitters are arranged to control axle counting devices, e.g. in the Soft 3 the Pulse generator 31, 32 and 33 for controlling the axle counting device ABF. This is used to monitor the occupancy or price status of the active zone of switch 3. The effective zone of a switch is limited by the three pulse generators. In the direction of flow the pulse generator 31 works for counting, the pulse generator 32 and 33 for the Counting the axes.

In the middle part of the drawing facilities are shown that the switch 3 are assigned. They are controlled by the pulse generators assigned to this switch and controlled by the axle counting device ABF. These facilities are for every switch provided; however, they are only once in the present drawing shown for a better overview.

In the lower part of the drawing there is essentially a job search register ASR and a main memory AS of the central information processing shown. While a department is running, the main memory AS contains, among other things, all for the switch control required information, i.e. the relevant sequence order and the target Acha number, etc. This information is at the beginning of the relevant Department from a central program memory (not shown) into a free one Memory line of the main memory AS entered. This one has so many memory lines How experience has shown that there are at most a number of departments running at the same time. All facilities for finding the line whose information is for a Control process are required because of a better overview of the drawing not with warp.

The assemblies marked S1 to 54 are memories that uniformly can be prepared via the lower entrance and queried via the upper entrance can. If the query is made after previous preparation, the the right output emits an output signal. The assemblies labeled T1 to T3 are gate circuits that are blocked via the left input via the lower input set and queried via the upper input with the aid of a clock pulse TP will. In the set state, these gate circuits give T1 to T3 via the respectively output lines led out on the right-hand side from output impulses. With ML designated assembly is an exit direction indicator, the effective zone of the turnout 3 is assigned. This exit direction indicator has the task of determining The direction in which a department moves out of the active zone assigned to the switch 7. For this purpose, the exit direction indicator AR is equipped with a self-preparation input connected to the counting pulse generator 33. This is the exit direction indicator AR Then each set - the exit direction indicator works like a memory - When an axle drives past the counting pulse generator 33. Happened to the outgoing one Axis the counting pulse generator 32, there is no setting of the exit direction indicator AR.

For the purposes of further explanation, it is assumed that a department has the Switch 3 travels and its active zone via the right strand 34 according to the exits the planned sequence order in accordance with the regulations.

After the testing process for a department, which the switch 3 previously has been completed, the effective zone of the switch 3 was counted by the counter ABF released. this is always the case when from the pulse generator 31 a number of axle counting pulses when entering the switch active zone to the Axle counting device ABF was issued and the same number of axle counting pulses from one of the two counting pulse generators 32 and 33 via the OR gate 01 to the Achzhleineinrichtung ABF was given. With this free message, the memory S1 and 52 prepared via their lower entrance. When entering the accepted Division into the active zone of switch 3 is indicated by the pulse generator 31 counting pulses the axle counting device ABF. As soon as the first axle of the department the counting pulse generator 33 actuated, this' gives on the one hand a counting pulse via the OR gate 01 to the axle counting device ABF. This counting pulse acts simultaneously on the Preparation input of the exit direction indicator AR, which prepares it is used as an indicator that the department over the said turnout effective zone the right strand 34 leaves. In addition, the counting pulse of the counting pulse generator is effective 33 to the memory 81, which is queried by this and at the same time as the exit message memory serving memory S3 prepared. All further counting pulses from the pulse generator 33 only affect the axle counting device ABF and the exit direction indicator AR off, since the memory 81 will not be available again until the active zone of the switch has been cleared 3 is prepared for another query.

At specified time intervals, the contractor registers ASR, the represents a part of the central program control, a query pulse via the Line L1 to memory 82 and S3.

As a result, the memory 83 is a test identifier via the line L2 which queries the exit direction indicator, the gate circuit T2 and the memory 54 is prepared. Since the department is the turnout effective zone Leaves via the right strand 34, this is done when the exit direction indicator is queried Directional identifier given by AR, character from a "1" information.

This direction indicator provides the gate circuit via line L3 T3 a. If the assumed division would be from the active zone of the switch 3 above the left one Drive out strand 35, the direction, identifier would consist of the information "Q".

The gate circuit T3 is designed 50 that mark this direction would not induce an attitude.

The memory 52, which is provided as a free message memory, is also queried by the job search register ASR.

The one to the exit direction indicator via the line L4 AR and, on the other hand, the output pulse delivered to gate circuit T1 acts on the one hand interrogating at the exit direction indicator AR and at the gate circuit T1 on the other hand hiring.

The processes initiated by this will be explained in more detail later.

By setting the gate circuit T2, these clock pulses are transmitted the OR GATE 03 to the work memory AS and to a line control 4. As a result the search process begins for that line of memory in which the information the department located in the active zone of the switch 3 are stored. That This "correct" memory line is found with the aid of not shown Facilities. If the rich-term memory line is found, the write process is started closed, and the process order becomes that for the changeover the switch position indicators provided for the switch 3 are queried with the aid of a device 5. With the activation of the gate circuit T2 by the test code of the memory S3 the memory S4 was prepared via the OR gate 02 at the same time.

When finding the correct line, there is a facility not shown Via the line L5 an identifier RZ to the memory S4, which is queried as a result At the same time, the job search register ASR is via the line L6 Impulse to protrude the device 5. Here, the switch position identifier is from the Device 5 given into a comparator V2, which, in addition, from the gate circuit T3 receives impulses corresponding to the direction indicator with the information "1", In this case, the point position identifier corresponds to the direction identifier.

The comparator V2 is now structured in such a way that if they match, a direction indicator with a switch position indicator no output impulses is output to the AND element K1, there is an output pulse from the comparator V2, so only always before if the characteristics to be compared do not match. When the memory 54 is queried, it sends an output pulse to the AND element K1 off. Since in the present case only one input of the AND element K1 of information is applied, it does not emit an output pulse. This is a sign of that the active zone of the switch 3 left department properly on the strand 34 extends.

The switch 3 is therefore in the position prescribed by the switch position indicator Location.

If the department would be over the left one as a result of the switch 3 not being converted Line 35 extended, ao had the extension direction indicator as Direction indicator the information "0" is output.

A comparison with the switch position identifier in the comparator V2 would then not have resulted in a match, and the AND element Kl would have a downhill mark issued. With the help of this symbol, the information content of the memory line deleted for the relevant department and a false display with actual. and Target track information is initiated.

After the last axis of the department has passed the zone of action of the switch 3 has left the right strand 34, and thus cleared the switch operating zone is, the total axis number of the department is entered in a comparator V1. aside from that the axle counting device ABF prepares the memories 81 and 52 when the message is clear again forward. The test process that is now beginning is intended to determine whether only the number of sell axles specified for the department at the clearing of the turnout effective zone was involved or whether as a result of another department that preceded the previous one has caught up, a greater number of axles than the target number of axles when the Switch effective zone was involved. During this test process, the through the exit direction detected by the exit direction indicator AR is taken into account and that Directional signs compared with the directional signs.

For a better understanding of the mode of action, it is now stated once which states the individual assemblies have before the test process. The memory S1 and 52 are prepared.

The memories 53 and S4 and the gate circuits T1 to T3 are not prepared or not set. The exit direction indicator AR is prepared by the pulse generator 33 when the last axle of the department is extended. As a result, the direction indicator is in the exit direction indicator with the information "1" saved. In the event of an interrogation pulse via line L1 from the job search register ASR gives the free message memory S2 an interrogation pulse over the line L4 the exit direction indicator AR.

At the same time the gate circuit T1 is opened. With everyone about the Gate circuit T1 is transmitted clock pulse to the memory 54 via the OR gate 02 prepared, In addition, these impulses control the main memory via the OR gate 03 AS and line control 4, when the correct line is found, the Comparison of the direction indicator from the exit direction indicator already described AR with the switch position identifier issued via the assembly 5, via the line L7 becomes the one for the relevant department from the correct line in the main memory The specified number of axles is entered in the comparator V1. The comparator V1 is at the same time, the actual number of axles determined by the axle counting device ABF is carried out. When querying the memory S4 with the help of the identifier given over the line L5 RZ the comparator V1 is queried. Depending on the comparison result, Various indicators issued via the line L8 of the comparator V1.

If the axle number comparison determines that the Zone of action of the switch 9 two different departments were involved, if how preparing mentioned the second division as a result of better running properties has caught up with the first department, a distinction must be made between different cases.

It is possible that both departments with their switch position identifier and the direction of extension coincide or not. But it is also possible that the mismatch exists only in one of the two departments. from of the four possible cases, only the first case should be considered as examples, at which agreement is found for both departments, and the second Case where the second division has a mismatch with the direction of exit Has turnout indicator.

In the first case, the AND element K1 does not give a wrong-way indicator the end. However, the comparator V1 determines an actual number of axles that is greater than that the target number of axles specified in the first department. Then it is over the line L8 output identifier is used after the one in the main memory AS Memory line is found, in which the information of the second on the retraction of the The effective zone of the switch 3 are saved, the target number of axles in addition to the target number of axles of the first department via the line L7 in the comparator V1. In the In the meantime, the memory 54 has been set again via the OR gate 02, so that with the identifier RZ on the line L5 another query of the memory S4 is possible. The identifier output by the memory 54 when it is queried queries the comparison result,; in the comparator V1. Since now the sum of the target number of axles with corresponds to the actual number of axles involved in the retraction, need in this If no messages are forwarded or evaluated, the test is complete completed for this case.

For the second instance of consideration it was assumed that the the following department would have to a different track than the preceding department should run. However, since the switch 3 could no longer be set in time, because the two departments had already caught up too far, the next one became Department to go wrong. In this case, too, the second comparison of the number of axles results Correspondence between the sum of the target number of axles and that of the axle counting device ABF reported actual number of axles of the two departments. As for the second department however, a switch position identifier from the main memory AS via the device 5 is issued, which differs from the direction indicator, gives the AND gate K1 the indicator for a wrong runner. In this case the PalschläuSerkennzeichen to clear the information of the wrongly running department in memory AS and to control the actual and target track display of the wrong-way runner are used.

After completing the test procedures described, the Gate circuits T1 to T3 with the help of a delay element from the line control 4 6 output impulse blocked.
