Definitions
- the invention relates to a method according to the preamble of patent claim 1.
- an in DE-OS 34 31 171 described track vacancy detection device provides the combination of the track sections adjacent to a defective metering point into a single longer track section (see page 11, lines 3 to 8).
- the majority of the counting errors can be corrected without redundant devices such as e.g. additional axis detectors must be kept available.
- This simple three-section correction requires three consecutive free track sections to be carried out. It is improved by further developments of the invention specified in the subclaims to an extended three-section correction, in which, as claimed in claim 2, the correction can also be carried out if one of the three track sections has already been occupied by a subsequent train and / or if as provided in claim 3, the last of the three sections has not yet been cleared.
- a railway line S is shown schematically, which is divided into track sections by metering points ZP1, ..., ZP4 equipped with computers.
- a number of axle counting computers assigned to several track sections reads out internal memories of the metering point computers, which contain a current number of axles and the direction of passage of the last registered axis, at regular intervals and manages a net counter A1, ..., A3, for each track section whose counter reading he added changes in the number of axes stored in the counting points delimiting the track section, depending on whether the section is entering or leaving the section with a positive or negative sign.
- a certain target counter reading (e.g. the counter reading "0") is a prerequisite for a free notification of the respective track section.
- the track section delimited by the metering points ZP1 and ZP2 is assigned the net counter A1
- the net counters A2 and A3 belong to the track sections which are delimited by the metering points ZP2 and ZP3 or by the metering points ZP3 and ZP4.
- FIG. 1 a also shows an error pattern that has arisen as a result of a positive incorrect count of + d axes at the metering point ZP3.
- the net counters A2 and A3 have been adversely affected by this incorrect count.
- the at point of delivery ZP3 incorrectly counted additional axes, moving in the direction of travel R, resulted in a negative deviation -d from the target meter reading (O) in the net counter A2, in the net counter A3 they left an excess of + d after clearing the assigned track section.
- the net counter A1 of the track section first traveled remained unaffected.
- a correction of the status of the net meters is permitted. It always starts from the net meter, which after clearing the associated track section has a meter reading that is lower than its target meter reading. Such a negative deviation from the target counter reading is a clear criterion for an incorrect count, since other operational events or faults cannot cause negative counter readings and, for example, it can be excluded that a train increases its number of axles while traveling. After a negative meter reading of a net meter is determined, the meter readings of the net meters of the neighboring sections are checked.
- the net meter which, after the associated track section has been cleared, has a positive deviation from its target meter reading, which corresponds to the amount of the negative deviation of the net meter of the neighboring section, may also be corrected, since this is almost certainly due to the incorrect count.
- a correction could only be out of place here and lead to a dangerous free message if at least one further metering error at an adjacent metering point and a train separation were present at the same time. Such a case is so unlikely that it can be excluded.
- the location of the incorrect count is always the point of delivery at which the track sections whose net counters show an opposite deviation from their target counter readings adjoin each other.
- the correction is made by adding the missing count d to Status of the net counter showing the negative deviation from the target counter reading and by deducting the shortfall d from the reading of the net counter showing the positive deviation from the target counter reading.
- FIG. 1b shows the distance S corresponding to FIG. 1a with a negative incorrect count at the point of delivery ZP2.
- the counter readings of the net counters A1 and A2 have been changed due to the insufficiently counted axes of a train traveling in the direction of travel R.
- the net counter A2 has the negative counter reading of -d, which is decisive for the admissibility of a correction, while the net counter A1 shows a positive remainder d of the same amount and the net counter A3 shows the unchanged target counter reading. The same applies here to the correction as to the case described in connection with FIG. 1a.
- the described three-section correction corresponds to the security of the "symmetrical four-correction" described in the journal article mentioned at the beginning, but only requires three free track sections to be able to be carried out.
- the three-section correction can be expanded.
- the net counter A1 of the neighboring section lying in the direction of travel shows a position Y above its target counter reading
- a check is carried out to determine whether a previous clearance message and its occurrence by counting axes in the direction of travel R is stored. If this is the case, a correction is made in accordance with the method described in connection with FIG. 1a, since the counter reading Y is due to a new occupation of the section via the counting point ZP1.
- the status of the net counter A1 remains unchanged, the net counter A2 receives the shortfall d corresponding to the counting error and the net counter A3 receives the amount d deducted.
- the adjacent track sections are combined into virtual track sections after metering points have failed, the contents of the net counters of the track sections which form the new subsections of the virtual track section are entered into a new net counter assigned to the virtual track section.
- the virtual track section can then be treated like an ordinary track section.

Abstract
Description
Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method according to the preamble of patent claim 1.
Ein solches Verfahren ist z.B. in "Signal + Draht 86 (1994) Heft 1/2, auf Seite 5 bis Seite 8 beschrieben. Die Korrektur von Zählfehlern ist dort von einem Vergleich der Zählergebnisse von in Fahrtrichtung aufeinanderfolgenden Zählpunkten abhängig. Tritt an einem von mehreren aufeinanderfolgenden Zählpunkten ein bleibender, gegenüber den Zählerständen der anderen Zählpunkte um 1 oder 2 erhöhter oder niedrigerer Zählerstand auf, so ist dies mit hoher Wahrscheinlichkeit auf eine Fehlzählung zurückzuführen und darf in vieler Fällen korrigiert werden. Entscheidend dafür, ob eine Korrektur durchgeführt werden darf und welche weiteren Bedingungen dazu erfüllt sein müssen, ist das Auftreten bestimmter Muster von an jeweils drei aufeinanderfolgenden Zählpunkten gewonnenen Zählergebnissen.Such a method is e.g. in "Signal + Draht 86 (1994) Issue 1/2, on
Neben Fehlzählungen können in Achszählanlagen auch Zählpunktausfälle auftreten und Betriebsbehinderungen verursachen. Um derartige Betriebsbehinderungen zu vermeiden, ist in einer in der DE-OS 34 31 171 beschriebenen Gleisfreimeldeeinrichtung die Zusammenfassung der an einen defekten Zählpunkt angrenzenden Gleisabschnitte zu einem einzigen längeren Gleisabschnitt vorgesehen (siehe Seite 11, Zeilen 3 bis 8).In addition to incorrect counts, counting point failures can also occur in axle counting systems and cause operational disabilities. In order to avoid such operational disabilities, an in DE-OS 34 31 171 described track vacancy detection device provides the combination of the track sections adjacent to a defective metering point into a single longer track section (see page 11, lines 3 to 8).
Da in einer derartigen Anlage eine Achszählung jedoch nicht zählpunktbezogen, sondern abschnittsbezogen durchgeführt wird, ist eine Korrektur von Zählpunkt-Zählerständen über Zählmuster, wie oben beschrieben, im Bereich eines ausgefallenen Zählpunktes nicht möglich.However, since in such a system an axle count is not performed on a point of delivery basis but rather on a section basis, it is not possible to correct the point of delivery counter values via counting patterns, as described above, in the area of a failed point of delivery.
Es ist deshalb Aufgabe der Erfindung, ein Korrokturverfahren anzugeben, das eine Zählfehlerkorrektur bei abschnittsbezogen arbeitenden Achszählanlagen erlaubt und das auch im Falle von Zählpunktausfällen, die durch Zusammenlegung von Gleisabschnitten in ihrer Auswirkung gemildert werden, angewandt werden kann.It is therefore an object of the invention to provide a correction method which allows counting error correction in section-related axle counting systems and which can also be used in the event of metering point failures which are mitigated in their effects by merging track sections.
Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in claim 1.
Mit dem Korrekturverfahren nach der Erfindung kann der größte Teil der Zählfehler korrigiert werden, ohne daß dazu redundante Einrichtungen wie z.B. zusätzliche Achsdetektoren vorgehalten werden müssen.With the correction method according to the invention, the majority of the counting errors can be corrected without redundant devices such as e.g. additional axis detectors must be kept available.
Diese einfache Dreiabschnittskorrektur, setzt zu ihrer Durchführung drei aufeinanderfolgende freie Gleisabschnitte voraus. Sie wird durch in den Unteransprüchen angegebene Weiterbildungen der Erfindung zu einer erweiterten Dreiabschnittskorrektur verbessert, bei der, wie dies Anspruch 2 ermöglicht, die Korrektur auch noch ausgeführt werden kann, wenn einer der drei Gleisabschnitte bereits von einem nachfolgenden Zug besetzt wurde und/oder wenn, wie in Anspruch 3 vorausgesetzt, der letzte der drei Abschnitte noch nicht geräumt wurde.This simple three-section correction requires three consecutive free track sections to be carried out. It is improved by further developments of the invention specified in the subclaims to an extended three-section correction, in which, as claimed in claim 2, the correction can also be carried out if one of the three track sections has already been occupied by a subsequent train and / or if as provided in claim 3, the last of the three sections has not yet been cleared.
Anhand von 2 Figuren sollen nun Ausführungsbeispiele des Korrekturverfahrens nach der Erfindung beschrieben werden.

- zeigt das Prinzip der Dreiabschnittskorrektur,
- Fig. 2

In Fig. 1a ist schematisch eine Eisenbahnstrecke S dargestellt, die durch mit Rechner ausgestattete Zählpunkte ZP1, ..., ZP4 in Gleisabschnitte unterteilt ist. Ein mehreren Gleisabschnitten zugeordneter, in der Figur nicht dargestellter Achszählrechner liest interne Speicher der Zählpunktrechner, die eine aktuelle Achszahl sowie die Durchgangsrichtung der zuletzt registierten Achse enthalten, in regelmäßigen Zeitabständen aus und verwaltet für jeden Gleisabschnitt einen Nettozähler A1, ..., A3, zu dessen Zählerstand er Änderungen der in den den Gleisabschnitt begrenzenden Zählpunkten gespeicherten Achszahlen, je nachdem, ob es sich um in den Abschnitt einlaufende oder aus diesem aus laufende Achsen handelt, mit positivem oder negativem Vorzeichen addiert. Ein bestimmter Soll-Zählerstand (z.B. der Zählerstand "0") ist Voraussetzung für eine Freimeldung des jeweiligen Gleisabschnitts.In Fig. 1a, a railway line S is shown schematically, which is divided into track sections by metering points ZP1, ..., ZP4 equipped with computers. A number of axle counting computers assigned to several track sections, not shown in the figure, reads out internal memories of the metering point computers, which contain a current number of axles and the direction of passage of the last registered axis, at regular intervals and manages a net counter A1, ..., A3, for each track section whose counter reading he added changes in the number of axes stored in the counting points delimiting the track section, depending on whether the section is entering or leaving the section with a positive or negative sign. A certain target counter reading (e.g. the counter reading "0") is a prerequisite for a free notification of the respective track section.
In Fig. 1 ist dem von den Zählpunkten ZP1 und ZP2 begrenzten Gleisabschnitt der Nettozähler A1 zugeordnet, die Nettozähler A2 und A3 gehören zu den Gleisabschnitten, die durch die Zählpunkte ZP2 und ZP3 bzw. durch die Zählpunkte ZP3 und ZP4 begrenzt sind.In Fig. 1, the track section delimited by the metering points ZP1 and ZP2 is assigned the net counter A1, the net counters A2 and A3 belong to the track sections which are delimited by the metering points ZP2 and ZP3 or by the metering points ZP3 and ZP4.
In Fig. 1a ist zudem ein Fehlerbild angegeben, das durch eine positive Fehlzählung von +d Achsen am Zählpunkt ZP3 entstanden ist. Durch diese Fehlzählung sind die Nettozähler A2 und A3 gegensinnig beeinflußt worden. Die am Zählpunkt ZP3 fälschlicherweise zusätzlich gezählten Achsen haben, in Fahrtrichtung R fahrend, im Nettozähler A2 zu einer negativen Abweichung -d vom Soll-Zählerstand (O) geführt, im Nettozähler A3 haben sie nach Räumung des zugeordneten Gleisabschnitts einen Überschuß von +d hinterlassen. Der Nettozähler A1 des zuerst befahrenen Gleisabschnitts blieb unbeeinflußt.FIG. 1 a also shows an error pattern that has arisen as a result of a positive incorrect count of + d axes at the metering point ZP3. The net counters A2 and A3 have been adversely affected by this incorrect count. The at point of delivery ZP3 incorrectly counted additional axes, moving in the direction of travel R, resulted in a negative deviation -d from the target meter reading (O) in the net counter A2, in the net counter A3 they left an excess of + d after clearing the assigned track section. The net counter A1 of the track section first traveled remained unaffected.
Eine Korrektur des Standes der Nettozähler ist in diesem Falle zulässig. Sie geht immer von dem Nettozähler aus, der nach Räumung des zugehörigen Gleisabschnitts einen gegenüber seinem Soll-Zählerstand niedrigeren Zählerstand aufweist. Eine solche negative Abweichung vom Soll-Zählerstand ist ein eindeutiges Kriterium für eine Fehlzählung, da andere betriebliche Ereignisse oder Störungen keine negativen Zählerstände verursachen können und beispielsweise ausgeschlossen werden darf, daß ein Zug während der Fahrt seine Achsenzahl erhöht. Nach Feststellung eines negativen Zählerstandes eines Nettozählers werden die Zählerstände der Nettozähler der Nachbarabschnitte geprüft. Der Nettozähler, der nach Räumung des zugehörigen Gleisabschnitts eine positive Abweichung von seinem Soll-Zählerstand aufweist, die im Betrag der negativen Abweichung des Nettozählers des Nachbarabschnitts entspricht, darf ebenfalls korrigiert werden, da diese mit an Sicherheit grenzender Wahrscheinlichkeit auch auf die Fehlzählung zurückzuführen ist. Eine Korrektur könnte hier nur dann fehl am Platz sein und zu einer gefährlichen Freimeldung führen, wenn mindestens ein weiterer Zählfehler an einem benachbarten Zählpunkt und gleichzeitig eine Zugtrennung vorliegen würden. Ein solcher Fall ist so unwahrscheinlich, daß er ausgeschlossen werden darf.In this case, a correction of the status of the net meters is permitted. It always starts from the net meter, which after clearing the associated track section has a meter reading that is lower than its target meter reading. Such a negative deviation from the target counter reading is a clear criterion for an incorrect count, since other operational events or faults cannot cause negative counter readings and, for example, it can be excluded that a train increases its number of axles while traveling. After a negative meter reading of a net meter is determined, the meter readings of the net meters of the neighboring sections are checked. The net meter, which, after the associated track section has been cleared, has a positive deviation from its target meter reading, which corresponds to the amount of the negative deviation of the net meter of the neighboring section, may also be corrected, since this is almost certainly due to the incorrect count. A correction could only be out of place here and lead to a dangerous free message if at least one further metering error at an adjacent metering point and a train separation were present at the same time. Such a case is so unlikely that it can be excluded.
Ort der Fehlzählung ist immer derjenige Zählpunkt, an dem die Gleisabschnitte, deren Nettozähler eine gegensinnige Abweichung von ihren Soll-Zählerständen zeigen, aneinander grenzen. Die Korrektur erfolgt durch Hinzufügen des Fehlzählbetrages d zum Stand des die negative Abweichung vom Soll-Zählerstand zeigenden Nettozählers und durch Abzug des Fehlbetrages d vom Stand des die positive Abweichung vom Soll-Zählerstand zeigenden Nettozählers.The location of the incorrect count is always the point of delivery at which the track sections whose net counters show an opposite deviation from their target counter readings adjoin each other. The correction is made by adding the missing count d to Status of the net counter showing the negative deviation from the target counter reading and by deducting the shortfall d from the reading of the net counter showing the positive deviation from the target counter reading.
Fig. 1b zeigt die der Fig. 1a entsprechende Strecke S mit einer negativen Fehlzählung im Zählpunkt ZP2. Im Fehlerbild sind die Zählerstände der Nettozähler A1 und A2 durch zu wenig gezählte Achsen eines in Fahrtrichtung R fahrenden Zuges verändert. Den für die Zulässigkeit einer Korrektur zunächst maßgebenden negativen Zählerstand von -d weist der Nettozähler A2 auf, während der Nettozähler A1 einen betragsgleichen positiven Rest d und der Nettozähler A3 den unveränderten Soll-Zählerstand zeigen. Für die Korrektur gilt hier dasselbe wie für den im Zusammenhang mit Fig. 1a beschriebenen Fall.FIG. 1b shows the distance S corresponding to FIG. 1a with a negative incorrect count at the point of delivery ZP2. In the error image, the counter readings of the net counters A1 and A2 have been changed due to the insufficiently counted axes of a train traveling in the direction of travel R. The net counter A2 has the negative counter reading of -d, which is decisive for the admissibility of a correction, while the net counter A1 shows a positive remainder d of the same amount and the net counter A3 shows the unchanged target counter reading. The same applies here to the correction as to the case described in connection with FIG. 1a.
Die beschriebene Dreiabschnittskorrektur entspricht bezüglich der Sicherheit der im eingangs genannten Zeitschriftenartikel beschriebenen "symmetrischen Viererkorrektur", benötigt jedoch nur drei freie Gleisabschnitte, um ausgeführt werden zu können.The described three-section correction corresponds to the security of the "symmetrical four-correction" described in the journal article mentioned at the beginning, but only requires three free track sections to be able to be carried out.
Um bei noch weniger, zur Verfügung stehenden freien Gleisabschnitten Zählfehler korrigieren zu können, kann die Dreiabschnittskorrektur erweitert werden.In order to be able to correct counting errors with even fewer free track sections available, the three-section correction can be expanded.
Fig. 2 zeigt schematisch drei Fälle, in denen nach Abprüfen zusätzlicher Bedingungen eine Zählfehlerkorrektur vorgenommen werden darf:
- 1. Die Dreiabschnittskorrektur nach erneuter Besetzung des in Fahrtrichtung zurückliegenen Gleisabschnitts.
- 2. Die Dreiabschnittskorrektur bei unvollständiger Räumung des in Fahrtrichtung vorausliegenden Gleisabschnitts und
- 3. Die Dreiabschnittskorrektur bei gleichzeitigem Vorliegen der beiden vorstehenden Fälle.
- 1. The three-section correction after renewed occupation of the track section back in the direction of travel.
- 2. The three-section correction in the event of incomplete clearance of the track section and in the direction of travel
- 3. The three-section correction in the presence of the two above cases.
Um eine erweiterte Dreiabschnittskorrektur ausführen zu können, müssen das Freifahren jedes Gleisabschnitts und die Richtung des Achsdurchgangs, der zu diesem Freifahren geführt hat, nach erneuter Besetzung mindestens bis zum nächsten Frei fahren gespeichert werden. Dann kann der Achszählrechner die Korrektur vornehmen.In order to be able to carry out an extended three-section correction, the clearing of each track section and the direction of the axis passage that led to this clearing must be saved at least until the next free driving after being occupied again. Then the axle counter computer can make the correction.
Zeigt, wie im Fehlerbild von Fig. 2, der Nettozähler A1 des in Fahrtrichtung zurückliegenden Nachbarabschnitts einen über seinem Soll-Zählerstand liegenden Stand Y, so wird geprüft, ob eine vorherige Freimeldung und deren Zustandekommen durch Auszählen von Achsen in Fahrtrichtung R gespeichert ist. Ist dies der Fall, so wird entsprechend dem im Zusammenhang mit Fig. 1a beschriebenen Verfahren korrigiert, da der Zählerstand Y auf eine Neubesetzung des Abschnitts über den Zählpunkt ZP1 zurückzuführen ist. Bei der Korrektur bleibt der Stand des Nettozählers A1 unverändert, der Nettozähler A2 bekommt den dem Zählfehler entsprechenden Fehlbetrag d zugeschlagen und der Nettozähler A3 erhält den Betrag d abgezogen.If, as in the fault diagram of FIG. 2, the net counter A1 of the neighboring section lying in the direction of travel shows a position Y above its target counter reading, then a check is carried out to determine whether a previous clearance message and its occurrence by counting axes in the direction of travel R is stored. If this is the case, a correction is made in accordance with the method described in connection with FIG. 1a, since the counter reading Y is due to a new occupation of the section via the counting point ZP1. During the correction, the status of the net counter A1 remains unchanged, the net counter A2 receives the shortfall d corresponding to the counting error and the net counter A3 receives the amount d deducted.
Letzteres geschieht auch, wenn der dem Nettozähler A3 zugehörige Gleisabschnitt noch nicht vollständig geräumt wurde und der Nettozähler A3 einen positiven Zählerstand aufweist, der größer als der Zählfehler, also d+x ist. Nach der Korrektur zeigt der Nettozähler A3 den Zählerstand x.The latter also occurs if the track section belonging to the net counter A3 has not yet been completely cleared and the net counter A3 has a positive counter reading which is greater than the counting error, ie d + x. After the correction, the net counter A3 shows the counter reading x.
Werden nach Ausfall von Zählpunkten die jeweils angrenzenden Gleisabschnitte zu virtuellen Gleisabschnitten zusammengefaßt, so werden die Inhalte der Nettozähler der Gleisabschnitte, die die neuen Teilabschnitte des virtuellen Gleisabschnitts bilden, in einen neuen, dem virtuellen Gleisabschnitt zugeordneten Nettozähler eingegeben. Der virtuelle Gleisabschnitt kann dann wie ein gewöhnlicher Gleisabschnitt behandelt werden.If the adjacent track sections are combined into virtual track sections after metering points have failed, the contents of the net counters of the track sections which form the new subsections of the virtual track section are entered into a new net counter assigned to the virtual track section. The virtual track section can then be treated like an ordinary track section.
