Abstract

The aim of the invention is to provide a method for automatically placing railway track sections (C), which had been indicated as being occupied due to an incorrect counting, in their initial position without directly comparing the number of axles of the vehicles entering and leaving the sections indicated as being occupied. To this end, a virtual railway track section (C4D) is assigned to each counting point (4) to be masked. Said virtual railway track section (C4D) spans this counting point and at least both contiguous railway track sections (C, D). The initial position of a railway track section (C), which had been indicated as being occupied due to an incorrect counting, is solely dependent on the indication indicating that at least one of the virtual railway track sections (C4D, B3C) spanning the same is free. This indication is provided by means of counting axles. The inventive method can be used for any complex railway track topology.

Description

Die Erfindung bezieht sich auf ein Verfahren nach dem Oberbegriff des Patentanspruches 1. Ein solches Verfahren ist aus der EP 0 739 802 A2 bekannt. Dort geht es speziell um die Auflösung von in Folge von Zählfehlern fehlerhaft besetzt gemeldeten Gleisabschnitten nach dem Erkennen dieser Zählfehler. Für jeden Zählpunkt, dessen Störungen oder Ausfälle maskiert werden sollen, wird in einem die Befahrungsmeldungen der Zählpunkte verarbeitenden, die Funktion von Zählwerken realisierenden Achszählrechner ein den betreffenden Zählpunkt überspannender virtueller Gleisabschnitt installiert, der die beiden an den Zählpunkt angrenzenden Gleisabschnitte umfasst. Stimmen die Zählergebnisse der Zählpunkte an den Enden dieses virtuellen Gleisabschnittes überein, dann wird auf den gestörten Zählpunkt im Sinne einer Zählkorrektur eingewirkt und der virtuelle Gleisabschnitt danach in der Reihenfolge, in der seine Gleisabschnitte besetzt wurden, abschnittsweise grundgestellt. Dies geschieht von demjenigen Achszählrechner aus, in dem die von den Zählpunkten stammenden Befahrungsmeldungen verarbeitet werden. Die Maßnahmen zur Zählfehlerkorrektur belasten die Achszählrechner in unerwünschter Weise, weil sie den Vergleich der an den einzelnen Zählpunkten erkannten Achszahlen erforderlich machen. Diese Achszahlen müssen ausschließlich für die Beseitigung von Zählstörungen in den Achszählrechnern zwischengespeichert und miteinander verglichen werden. Eigentliche Aufgabe der Achszählrechner ist aber die Gleisüberwachung durch fahrrichtungsabhängiges Zählen von Zählimpulsen nach dem Prinzip der Nettozählung ohne zusätzliche Speicherung der jeweils an einem Zählpunkt vorbeigefahrenen Fahrzeugachsen.The invention relates to a method according to the preamble of claim 1. Such a method is known from EP 0 739 802 A2. There, it is specifically about the resolution of erroneously occupied due to counting errors track sections after detecting these counting errors. For each metering point whose malfunctions or failures are to be masked, a virtual track section spanning the respective metering point is installed in an axle counting computer which processes the traffic reports of the metering points and realizes the function of totalizers, comprising the two track sections adjoining the metering point. If the counting results of the points of delivery coincide at the ends of this virtual track section, then the disturbed metering point is acted upon in the sense of a count correction and the virtual track section is then based in sections in the order in which its track sections were occupied. This is done by that Achszählrechner in which the derived from the points of delivery traffic messages are processed. The measures for counting error correction load the Achszählrechner in an undesirable manner, because they make it necessary to compare the detected at the individual metering points axle numbers. These axle numbers must be buffered and compared with one another exclusively for the elimination of counting disturbances in the axle counting computers. Actual task of Achszählrechner but is the track monitoring by driving direction-dependent counting of counting pulses according to the principle of net counting without additional storage of each passed at a counting point vehicle axes.

Aus "Signal + Draht", 87(1995)5, Seiten 156 bis 162 ist ein Verfahren zur Korrektur eines ausgefallenen Zählpunktes bekannt, bei dem die beiden angrenzenden Freimeldeabschnitte zu einem virtuellen Abschnitt zusammengefasst werden. Die Freimeldung erfolgt erst dann, wenn der virtuelle Abschnitt geräumt ist. Hierzu werden die in den virtuellen Gleisabschnitt eingefahrenen Achsen mit den aus ihm ausgefahrenen Achsen zahlenmäßig erfasst und miteinander verglichen.From "Signal + Wire", 87 (1995) 5, pages 156 to 162, a method for correcting a failed counting point is known in which the two adjacent free field sections are combined into a virtual section. The free message only takes place when the virtual section has been cleared. For this purpose, the axes retracted into the virtual track section are numerically recorded with the axes extended from it and compared with each other.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren nach dem Oberbegriff des Patentanspruches 1 so auszugestalten, dass auf eine zusätzliche Speicherung und einen zusätzlichen Vergleich der an den Ein- und Ausfahrzählpunkten von virtuellen Gleisabschnitten detektierten Fahrzeugachsen durch Achszählrechner bei der Maskierung von Störungen und Ausfällen an den Zählpunkten verzichtet werden kann.Object of the present invention is to provide a method according to the preamble of claim 1 such that on an additional storage and an additional comparison of the detected at the entry and Ausfahrzählpunkten of virtual track sections vehicle axes by Achszählrechner in the masking of faults and failures at the Counting points can be dispensed with.

Die Erfindung löst diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruches 1. Die Maskierung von Störungen und Ausfällen ist damit allein abhängig von den Zählergebnissen der Achszählrechner beim Erfassen der sich innerhalb eines Gleisabschnittes oder eines virtuellen Gleisabschnittes aufhaltenden Fahrzeugachsen.The invention solves this problem by the characterizing features of claim 1. The masking of faults and failures is thus solely dependent on the count results of Achszählrechner when detecting the vehicle within a track section or a virtual track section stopping vehicle axles.

Für den Fall, dass ein virtueller Gleisabschnitt störungsbedingt als befahren angenommen wird, ist vorgesehen, diesen grundzustellen, wenn die von ihm überspannten realen Gleisabschnitte oder alle ihn überdeckenden benachbarten virtuellen Gleisabschnitte freigemeldet sind. Damit verschwinden auch störungsbedingte Besetztmeldungen virtueller Gleisabschnitte automatisch dann, wenn feststeht, dass diese Abschnitte tatsächlich nicht mehr befahren sind.In the event that a virtual track section is assumed to be a traffic due to the disturbance, it is intended to ground it if the real track sections spanned by it or all the adjacent virtual track sections covering it are cleared. As a result, disturbance-related busy messages of virtual track sections automatically disappear when it is clear that these sections are actually no longer used.

Vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Verfahrens sind in den Unteransprüchen angegeben.Advantageous embodiments and further developments of the method according to the invention are specified in the subclaims.

So sollen die Achszählrechner die Gleisüberwachung ausschließlich nach dem Prinzip der Nettozählung durchführen, wobei die Freimeldung der einzelnen Gleisabschnitte durch ODER-Verknüpfung von Freimeldungen für die einzelnen Abschnitte bewirkt wird. Insbesondere soll die Grundstellung der Gleisabschnitte außerhalb der Zählpunktrechner, vorzugsweise in einem Stellwerk, vorgenommen werden können, das die Ergebnismeldungen der Nettozähler verarbeitet; dabei werden die Achszählrechner durch die vom Stellwerk vorzunehmenden Grundstellungen in gar keiner Weise zusätzlich belastet.Thus, the Achszählrechner should perform the track monitoring exclusively on the principle of net counting, the free message of the individual track sections is caused by OR linkage of free messages for the individual sections. In particular, the basic position of the track sections outside the counting point computer, preferably in a signal box, can be made, which processes the result reports of the net meter; In this case, the Achszählrechner be burdened by the assumptions to be made by the interlocking basic positions in any way in any way.

Für die Einfahr- und Ausfahrzählpunkte von Streckenbereichen können vorteilhaft Zählpunktverdopplungen vorgesehen sein, um für die Ein- und Ausfahrzählpunkte kurze virtuelle Gleisabschnitte bilden zu können. Damit sind dann auch Störungen und Ausfälle an diesen Ein- und Ausfahrzählpunkten überdeckbar.Advantageously, counting point duplications can be provided for the entry and exit counting points of route areas in order to be able to form short virtual track sections for the entry and exit counting points. This also makes it possible to cover faults and failures at these entry and exit points.

Die Erfindung ist nachstehend anhand von in der Zeichnung verdeutlichten Ausführungsbeispielen näher erläutert. Die Zeichnung zeigt in

Figur 1
ein einzelnes Gleis mit einer Vielzahl von Zählpunkten und den durch diese Zählpunkt definierten realen und virtuellen Gleisabschnitten, in
Figur 2

The invention is explained below with reference to embodiments illustrated in the drawings. The drawing shows in
FIG. 1
a single track with a large number of metering points and the real and virtual track sections defined by these metering points, in
FIG. 2
a corresponding representation for a rail junction and in
FIG. 3

Die in Figur 1 dargestellte Strecke ist durch Zählpunkte 1 bis 8 in aneinander grenzende Gleisabschnitte A bis G beliebiger Länge unterteilt. Jeder Zählpunkt weist streckenseitig zwei Sensoren zum Erkennen vorüberlaufender Fahrzeugräder auf. Die Sensormeldungen jedes Zählpunktes werden entweder vor Ort in fahrrichtungsabhängige Zählimpulse umgewandelt und dann an meist ferne Zählwerke übermittelt oder diese Umsetzung erfolgt erst an den Zählwerken. Die Zählwerke sind heute üblicherweise als Achszählrechner ausgeführt. Die an einem Zählpunkt in der einen Fahrrichtung vorbei fahrenden Fahrzeugachsen werden vom Achszählrechner abschnittsbezogen in einen Zähler eingezählt, die in der anderen Richtung vorbei fahrenden Achsen werden ausgezählt. Ist die Summe der in den Zähler eingezählten Achsen gleich der Summe der aus ihm ausgezählten Achsen, so wird der zugehörige Abschnitt freigemeldet, andernfalls wird er besetzt gemeldet.The route shown in Figure 1 is divided by count points 1 to 8 in adjacent track sections A to G of any length. Each metering point has two sensors on the trackside to detect passing vehicle wheels. The sensor messages of each metering point are either locally converted into direction-dependent counting pulses and then transmitted to mostly distant counters or this conversion takes place only at the counters. The counters are usually designed today as Achszählrechner. The vehicle axles traveling past a metering point in one direction of travel are counted by the axle counting computer into a counter in sections, the axles traveling in the other direction are counted. If the sum of the axes enumerated in the counter is equal to the sum of the axes counted out of it, the corresponding section is cleared, otherwise it is reported busy.

Für eine selbsttätige Grundstellung von infolge einer Störung oder eines Ausfalls besetzt gemeldeten Gleisabschnitten ist jedem Zählpunkt, dessen Störung oder Ausfall überdeckt werden soll, in an sich bekannter Weise ein virtueller Gleisabschnitt zugeordnet, der diesen Zählpunkt sowie die beidseits angrenzenden Gleisabschnitte inklusive der diesen zugeordneten Zählpunkte beinhaltet. Die virtuellen Gleisabschnitte sind in der Zeichnung mit der Ziffer des jeweils zu maskierenden Zählpunktes und den Buchstaben der diesem Zählpunkt benachbarten Gleisabschnitte bezeichnet. So wird z. B. der Gleisfreimeldeabschnitt C durch die Zählpunkte 3 und 4 begrenzt, der den Zählpunkt 4 und die Gleisabschnitte C und D überdeckende virtuelle Gleisabschnitt C4D durch die Zählpunkte 3 und 5.For an automatic basic position of occupied due to a fault or a failure track sections each counting point whose failure or failure is to be covered, assigned in a conventional manner, a virtual track section that includes this point of delivery and the adjacent track sections including its associated points of delivery , The virtual track sections are indicated in the drawing by the numeral of the respective metering point to be masked and the letters of the track sections adjacent to this metering point. So z. B. the train detection section C limited by the metering points 3 and 4, the metering point 4 and the track sections C and D covering virtual track section C4D through the counting points 3 and 5.

Eine von der Achszählung bereitgestellte Freimeldung eines Abschnittes ist als signaltechnisch sicher anzusehen. Es ist zwar durchaus möglich, dass ein Achszählabschnitt fälschlich besetzt gemeldet wird, z. B. bei Ausfall oder Störung eines Zählpunktes; es kann aber mit ausreichender Wahrscheinlichkeit ausgeschlossen werden, dass ein Achszählabschnitt fehlerhaft freigemeldet wird. Deshalb kann die folgende Annahme getroffen werden: Liefert ein Gleisfreimeldeabschnitt eine Besetztmeldung und ein diesen Gleisfreimeldeabschnitt überspannender virtueller Abschnitt eine Freimeldung oder liefert der Gleisfreimeldeabschnitt eine Freimeldung und ein diesen Gleisfreimeldeabschnitt überspannender virtueller Abschnitt eine Besetztmeldung, kann davon ausgegangen werden, dass der Gleisfreimeldeabschnitt tatsächlich frei ist und die jeweilige Besetztmeldung ausfall- oder störungsbedingt ist. Auf das konkrete Ausführungsbeispiel der Figur 1 bezogen bedeutet dies z. B., dass dann, wenn die Achszählung für den Gleisfreimeldeabschnitt C eine Besetztmeldung und für den virtuellen Abschnitt C4D eine Freimeldung liefert, davon ausgegangen werden kann, dass der Gleisfreimeldeabschnitt C tatsächlich frei ist. Ebenso kann, wenn die Achszählung für den Gleisfreimeldeabschnitt C eine Freimeldung aber für den virtuellen Abschnitt C4D oder den virtuellen Abschnitt B3C eine Besetztmeldung liefert, davon ausgegangen werden, dass der Gleisfreimeldeabschnitt C tatsächlich frei ist. Damit ergibt sich die Freimeldung eines Gleisabschnittes aus einer ODER-Verknüpfung der Freimeldungen des betreffenden Gleisabschnittes und der den Gleisabschnitt überspannenden virtuellen Gleisabschnitte. Die Freimeldung eines Gleisabschnittes ist damit nurmehr noch mittelbar abhängig von den jeweils detektierten Achszahlen, nicht aber von einem Vergleich der insgesamt an den einzelnen Zählpunkten vorbeigelaufenen Achszahlen. Die Freimeldung ist vielmehr ausschließlich abhängig von den Frei- und Besetztmeldungen für die einzelnen realen und virtuellen Gleisabschnitte.A free message of a section provided by the axle counting can be regarded as safe in terms of signaling. Although it is quite possible that a Achszählabschnitt is reported wrongly occupied, z. B. in case of failure or malfunction of a point of delivery; but it can be ruled out with sufficient probability that a Achszählabschnitt is incorrectly cleared. Therefore, the following assumption can be made: If a train free reporting section delivers a busy message and a virtual section spanning this train free reporting section provides a clear message or delivers the train free reporting section a free message and this track train detection section spanning virtual section a busy message, it can be assumed that the train free reporting section is actually free and the respective busy message is due to failure or interference. Based on the specific embodiment of Figure 1, this means z. B., that when the axle counting for the train detection section C provides a busy message and for the virtual section C4D a free message, it can be assumed that the train detection section C is actually free. Likewise, if the axle count for the train free reporting section C provides a clear message but a busy message for the virtual section C4D or the virtual section B3C, it can be assumed that the train free reporting section C is actually free. This results in the clearing of a track section from an OR link of the clear messages of the track section concerned and the track section spanning virtual track sections. The clear message of a track section is thus only indirectly dependent on the respectively detected axle numbers, but not by a comparison of the total passed at the individual metering points axle numbers. Rather, the free message is exclusively dependent on the free and busy messages for the individual real and virtual track sections.

Ein Achszählabschnitt, der störungsbedingt besetzt gemeldet ist, in dem sich aber keine Achsen befinden können, soll erfindungsgemäß über die ODER-Verknüpfung der für diesen Abschnitt und die zugehörigen virtuellen Abschnitte vorliegenden Freimeldungen automatisch grundgestellt werden. Allerdings darf ein solcher Gleisabschnitt nur grundgestellt werden, wenn die letzte gezählte Achse eine ausgezählte Achse ist. Ist die letzte Achse eine eingezählte Achse, dann wird die Grundstellung zeitlich verschoben, bis eine Achse ausgezählt wird.An axis counting section, which is reported to be busy due to the failure, but in which no axes can be located, is to be automatically grounded according to the invention via the OR link of the free messages present for this section and the associated virtual sections. However, such a track section may only be used if the last counted axis is a counted axis is. If the last axis is a counted axis, then the basic position is shifted in time until an axis is counted.

Ist z. B. der Gleisfreimeldeabschnitt C besetzt gemeldet, aber der virtuelle Abschnitt C4D oder der virtuelle Abschnitt B3C freigemeldet, dann soll der Gleisfreimeldeabschnitt C automatisch grundgestellt werden.Is z. B. the train detection section C occupied busy, but the virtual section C4D or the virtual section B3C cleared, then the train detection section C should be automatically based.

Nach der gleichen Logik kann ein virtueller besetztgemeldeter Gleisabschnitt automatisch grundgestellt werden, wenn alle Gleisfreimeldeabschnitte, die der virtuelle Gleisabschnitt überspannt, freigemeldet sind. Ist z. B. der virtuelle Gleisabschnitt C4D besetzt gemeldet obwohl die von ihm überspannten Freimeldeabschnitte C und D freigemeldet sind, so kann der virtuelle Gleisabschnitt C4D automatisch grundgestellt werden. Das Gleiche ist auch möglich, wenn die diesen virtuellen Gleisabschnitt jeweils mindestens teilweise, zusammen aber vollständig überspannenden virtuellen Gleisabschnitte B3C und D5E freigemeldet sind.Following the same logic, a virtual busy track section may be automatically grounded if all track free reporting sections spanned by the virtual track section are cleared. Is z. B. the virtual track section C4D occupied reported although the spanned by him free reporting sections C and D are cleared, the virtual track section C4D can be automatically based. The same is also possible if the virtual track sections B3C and D5E are at least partially, but together completely spanned, free.

Der besondere Vorteil des erfindungsgemäßen Verfahrens zum Frei- und Besetztmelden von Gleisabschnitten besteht darin, dass in die Grundstellung besetztgemeldeter Abschnitte nicht mehr die Achszahlen der an den Zählpunkten vorübergelaufenen Fahrzeugachsen einbezogen werden, sondern nur die Freimeldungen der Abschnitte, wie sie von den Achszählrechnern zur Verfügung gestellt werden. Die Grundstellung kann deshalb von einer Einrichtung außerhalb der Achszählung vorgenommen werden, beispielsweise von einem Stellwerk.The particular advantage of the method according to the invention for free and busy reporting of track sections is that in the basic position of busy sections no longer included the number of axles of the past at the points of delivery vehicle axles, but only the free messages of the sections, as provided by the Achszählrechnern available become. The basic position can therefore be made by a device outside of the axle counting, for example, by a signal box.

Figur 2 zeigt die Anwendung der Erfindung bei einem sich verzweigenden Gleis. Die Bezeichnung der Zählpunkte sowie der realen und virtuellen Gleisabschnitte folgt der der Figur 1. Die Weiche wird durch einen gemeinsamen Gleisabschnitt überwacht, der durch die Zählpunkte 3, 4 und 9 begrenzt ist.. Bleibt die Besetztmeldung des annahmegemäß vollständig geräumten Gleisabschnittes C als Folge einer Störung am Zählpunkt 3 stehen, so erfolgt die automatische Grundstellung dieses Gleisabschnittes, wenn mindestens einer der virtuellen Gleisabschnitte B3C, C4D oder C9H freigemeldet wird, d. h. z. B. für Abschnitt B3C, wenn die Anzahl der über die Zählpunkte 2, 4 und 9 fahrrichtungsabhängig ein- und ausgefahrenen Achsen null ist.Figure 2 shows the application of the invention to a branching track. The name of the points of delivery as well as the real and virtual track sections follows that of Figure 1. The switch is monitored by a common track section, which is limited by the metering points 3, 4 and 9. If the Busy message of assuming fully cleared track section C remains as a result of a disturbance at the point of delivery 3 Thus, the automatic basic position of this track section takes place when at least one of the virtual track sections B3C, C4D or C9H is cleared, ie, for example, for section B3C, if the number of on the count points 2, 4 and 9 depending on the direction of travel depending and extended axes is zero.

Ohne besondere Vorkehrungen kann der erste und der letzte Zählpunkt eines Gleisfreimeldebereiches nicht durch einen virtuellen Abschnitt überspannt werden, d. h. etwaige dort auftretende Zählstörungen ließen sich nicht ohne weiteres unwirksam machen. Wenn dies jedoch gefordert würde, wäre es möglich, dies dadurch zu erreichen, dass die betreffenden Ein- und Auszählpunkte verdoppelt werden, wie es in Figur 3 für den als Einfahrzählpunkt angenommenen Zählpunkt 2 dargestellt ist. Ein in geringem Abstand zu diesem angeordneter zusätzliche Zählpunkt 1 macht es möglich, über den zu maskierenden Zählpunkt 2 einen virtuellen Gleisabschnitt A2B zu spannen, über den die Grundstellung des Gleisabschnittes 2 herbeigeführt werden kann. Eine solche Grundstellung würde aber auch automatisch vorgenommen werden, wenn beim Vorrücken des Zuges der virtuelle Gleisabschnitt B3C freigemeldet würde; allerdings würde diese Grundstellungsmeldung zeitlich später erfolgen.Without special precautions, the first and the last point of delivery of a track vacancy reporting area can not be spanned by a virtual section, i. H. Any counting disturbances occurring there could not be rendered ineffective without further ado. However, if this were required, it would be possible to achieve this by doubling the respective counting and counting points, as shown in FIG. 3 for the counting point 2 assumed to be the entry point. An additional metering point 1 arranged at a small distance from this makes it possible to span a virtual track section A2B via the metering point 2 to be masked, via which the basic position of the track section 2 can be brought about. Such a basic position would, however, also be carried out automatically if the virtual track section B3C were cleared when the train advanced. However, this attitude would be later in time.

Bei den vorstehend näher erläuterten Ausführungsbeispielen überspannen die virtuellen Gleisabschnitte jeweils zwei zu beiden Seiten eines zu maskierenden Zählpunktes angeordnete Gleisabschnitte. Es ist aber auch möglich, die virtuellen Gleisabschnitte jeweils über mehr als zwei Gleisabschnitte zu spannen. Die Anzahl der überspannten Gleisabschnitte und damit die Länge der virtuellen Gleisabschnitte ist beliebig zu wählen. Wichtig ist lediglich, dass die virtuellen Gleisabschnitte jeweils lückenlos aneinander grenzende Gleisabschnitte überspannen, wobei ihre Anordnung zum jeweils zu maskierenden Zählpunkt durchaus unsymmetrisch sein kann.In the exemplary embodiments explained in more detail above, the virtual track sections span two each arranged on both sides of a metering point to be masked Track sections. However, it is also possible to span the virtual track sections over more than two track sections. The number of spanned track sections and thus the length of the virtual track sections is arbitrary. It is only important that the virtual track sections each spans gapless adjoining track sections, their arrangement can be quite asymmetrical to each point of coverage to be masked.

Das erfindungsgemäße Verfahren lässt sich ohne besondere Vorkehrungen auf beliebig komplexe Gleistopologien mit Weichen, Abschnitten, Kreuzungen usw. anwenden, indem deren Zählpunkten die für ihre Maskierung nach der Erfindung jeweils vorgesehenen virtuellen Gleisabschnitte zugeordnet werden.The inventive method can be applied without special precautions to arbitrarily complex Gleistopologien with switches, sections, intersections, etc., by their counting points are assigned to their respective masking according to the invention provided virtual track sections.

Der besondere Vorteil des erfindungsgemäßen Verfahrens besteht darin, dass die automatische Grundstellung fehlzählungsbedingt besetzt gemeldeter Gleisabschnitte allein auf Grund der für die einzelnen realen und virtuellen Gleisabschnitte verfügbaren Freimeldungen herbeigeführt werden kann, ohne dass es hierzu an den Zählwerken oder den Achszählrechnern besonderer Maßnahmen für die zahlenmäßige Integration von Befahrungsmeldungen bedarf.The particular advantage of the method according to the invention is that the automatic basic position miscounted reported track sections can be brought about solely for the individual real and virtual track sections free messages without it for this purpose at the counters or the Achszählrechnern special measures for numerical integration requires traffic reports.

Claims (6)

  1. Method for indicating whether railway track sections are free or occupied, each of which track sections is bounded by counting points which generate travel-over messages for the track monitoring by means of associated counters or axle counting computers when vehicle wheels pass over them, in each case a virtual track section, which comprises at least the two track sections directly adjoining the counting point, being temporarily extended over the respective counting points in order to cover any counting errors, the return to normal of the track section (C) being made dependent on the free-indication message of at least one of the virtual track sections (B3C, C4D) extending over it, characterized and in that the return to normal of the virtual track section (C4D) is made dependent on the two real track sections (C, D) over which the latter extends or the virtual track sections (B3C, D5E) which extend completely over the latter in its entirety being indicated as being free.
  2. Method according to Claim 1, characterized in that the functions of net counters for counting in and counting out pulses in or from associated track sections and virtual track sections are implemented in the counters or axle counting computers, and in that the free-indication signals of the net counters are used to return to normal any sections indicated as being occupied, by means of OR logic operations.
  3. Method according to Claim 2, characterized in that the return to normal of a track section is brought about inside or outside the respective counter or axle counting computer in a separate processing level from the free-indication messages, available there, of the counter or axle counting computer.
  4. Method according to one of Claims 1 to 3, characterized in that the counting points (2) are doubled (1, 2) at the entry end and/or exit end of a track region monitored by a counter or an axle counting computer, in order to form in each case one virtual track section (A2B in Fig. 3) which extends beyond the entry and exit track section, over the entry and exit end.
  5. Method according to one of Claims 1 to 4, characterized in that the return to normal of a track section which is indicated as being occupied or a virtual track section which is indicated as being occupied is made dependent on the fact that the axle last counted is an axle which has exited the respective section.
  6. Method according to one of Claims 1 to 5, characterized in that the effective free-indication message, evaluated by the interlocking cabin logic, of a track section is determined from the application of the logic OR operation to the free-indication message (C) signaled for this section by the axle counting computer and the free-indication messages of one or more virtual track sections (B3C, C4D) which extend over this section.
