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

Beschreibungdescription
Verfahren zur Gleisfrei- und -besetztmeldungTrack vacancy and occupancy notification procedure
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 Zählfeh- 1er. 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 u fasst. 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. Aus "Signal + Draht", 87(1995)5, Seiten 156 bis 162 ist ein Verfahren zur Korrektur eine sausgefallenen Zählpunktes bekannt, bei dem die beiden angrenzenden Freimeldeabschnitte zu einem virtuellen Abschnitt zusammengefasst werden. Die Frei- meidung 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.The invention relates to a method according to the preamble of claim 1. Such a method is known from EP 0 739 802 A2. It is specifically about the resolution of track sections reported incorrectly occupied as a result of counting errors after these counting errors have been recognized. For each metering point, the malfunctions or failures of which are masked, an axle track computer that processes the metering points' traffic information and realizes the function of meters is installed, a virtual track section spanning the metering point in question, which contains the two track sections u adjacent to the metering point. If the counting results of the metering points at the ends of this virtual track section match, then the disturbed metering point is acted on in the sense of a counting correction and the virtual track section is then set in sections in the order in which its track sections were occupied. This is done from the axle counting computer in which the traffic reports originating from the metering points are processed. The measures for counting error correction place an undesirable burden on the axle counting computer because they make it necessary to compare the number of axles recognized at the individual counting points. These axis numbers have to be stored in the axle counter computers and compared with one another exclusively for the purpose of eliminating counting faults. However, the actual task of the axle counting computer is to track the track by counting counting pulses based on the direction of travel, based on the principle of net counting without additional storage of the vehicle axles that have passed each metering point. From "Signal + Draht", 87 (1995) 5, pages 156 to 162, a method for correcting a failed metering point is known, in which the two adjacent free reporting sections are combined to form a virtual section. The release is only made when the virtual section has been cleared. For this purpose, the axes retracted into the virtual track section are numerically recorded and compared with the axes extended from it.
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 Achs- zählrechner bei der Maskierung von Störungen und Ausfällen an den Zählpunkten verzichtet werden kann.The object of the present invention is to design a method according to the preamble of claim 1 such that additional axle storage and an additional comparison of the vehicle axles detected at the entry and exit counting points of virtual track sections by axle counting computers in the masking of faults and failures can be dispensed with at the metering points.
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 therefore solely dependent on the counting results of the axle counting computer when detecting the vehicle axles located within a track section or a virtual track section.
Für den Fall, dass ein virtueller Gleisabschnitt stδrungsbe- dingt 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. Vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Verfahrens sind in den Unteransprüchen angegeben.In the event that a virtual track section is assumed to be trafficked due to the fault, provision is made for this to be the case if the real track sections spanned by it or all neighboring virtual track sections covering it are registered. This also means that fault-related occupancy reports for virtual track sections automatically disappear when it is certain that these sections are actually no longer used. Advantageous refinements and 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.For example, the axle counting computer should perform the track monitoring exclusively on the principle of net counting, the free notification of the individual track sections being effected by OR linking free reports for the individual sections. In particular, the basic position of the track sections should be able to be made outside the metering point computer, preferably in a signal box, which processes the result reports of the net meters; the axle counting computer is in no way additionally burdened by the basic positions to be carried out by the signal box.
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.Counting point doublings can advantageously 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. Malfunctions and failures at these entry and exit metering points can then also be covered.
Die Erfindung ist nachstehend anhand von in der Zeichnung verdeutlichten Ausführungsbeispielen näher erläutert. DieThe invention is explained below with reference to exemplary embodiments illustrated in the drawing. The
Zeichnung zeigt in Figur 1 ein einzelnes Gleis mit einer Vielzahl von Zählpunkten und den durch diese Zählpunkt definierten realen und virtuellen Gleisabschnitten, in1 shows a single track with a large number of metering points and the real and virtual track sections defined by this metering point, in FIG
Figur 2 eine entsprechende Darstellung für eine Gleisverzweigung und in Figur 3 wieder ein einzelnes Gleis mit einem verdoppelten Zählpunkt am Einfahrende des Gleises . 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 aus- gezählten Achsen, so wird der zugehörige Abschnitt freigemeldet, andernfalls wird er besetzt gemeldet.2 shows a corresponding representation for a track branching and in FIG. 3 again a single track with a doubled counting point at the entry end of the track. The route shown in Figure 1 is divided by metering points 1 to 8 into adjacent track sections A to G of any length. On the track side, each metering point has two sensors for detecting passing vehicle wheels. The sensor messages of each metering point are either converted on the spot into counting pulses that depend on the direction of travel and then transmitted to mostly remote counters, or this conversion only takes place at the counters. Today, the counters are usually designed as axle counting computers. The vehicle axles passing a counting point in one direction of travel are counted into a counter by the axle counting computer, and the axles passing in the other direction are counted. If the sum of the axes counted in the counter is equal to the sum of the axes counted out of it, the corresponding section is released, otherwise it is reported occupied.
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. 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 über- spannender virtueller Abschnitt eine Freimeldung oder liefert For an automatic basic position of track sections reported as a result of a malfunction or a failure, each metering point whose malfunction or failure is to be covered is assigned a virtual track section in a manner known per se, which contains this metering point and the track sections adjoining on both sides, including the metering points assigned to them , The virtual track sections are designated in the drawing with the number of the metering point to be masked and the letters of the track sections adjacent to this metering point. So z. B. the track vacancy reporting section C is limited by the metering points 3 and 4, the virtual track section C4D covering the metering point 4 and the track sections C and D by the metering points 3 and 5. A free notification of a section provided by the axle counting is to be regarded as safe in terms of signaling. It is quite possible that an axle counting section is reported incorrectly occupied, e.g. B. in the event of failure or malfunction of a metering point; it can, however, be excluded with sufficient probability that an axle counting section will be reported incorrectly. The following assumption can therefore be made: Does a track vacancy reporting section provide a busy signal and a virtual section that spans this track vacancy reporting section delivers a vacancy report or delivers
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 jeweili- ge 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 Gleis- freimeldeabschnitt 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 detek- tierten 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.If the track vacancy detection section is a vacant message and a virtual section that spans this track vacancy detection section is a busy message, it can be assumed that the track vacancy detection section is actually free and that the respective busy message is due to failure or malfunction. Based on the specific embodiment of Figure 1, this means z. B. that if the axle count for the track vacancy reporting section C provides a busy message and for the virtual section C4D a vacancy report, it can be assumed that the track vacancy reporting section C is actually free. Likewise, if the axle count for the track vacancy reporting section C provides a vacancy report but for the virtual section C4D or the virtual section B3C a busy report, it can be assumed that the track vacancy reporting section C is actually free. The free notification of a track section thus results from an OR operation of the free messages of the relevant track section and the virtual track sections spanning the track section. The free notification of a track section is now only indirectly dependent on the number of axles detected in each case, but not on a comparison of the total number of axles running past the individual metering points. Rather, the free notification 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 Ab- schnitt 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 axle counting section that is reported to be occupied due to a fault, but in which no axes can be located, is to be automatically established according to the invention by means of the OR operation of the free messages available for this section and the associated virtual sections. However, such a section of track may only be used if the last counted axis is a counted axis is. If the last axis is a counted axis, 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. For example, if the track vacancy reporting section C is reported to be occupied, but the virtual section C4D or the virtual section B3C is vacant, then the track vacancy reporting section C is to be automatically set.
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 überspann- ten 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.According to the same logic, a virtual occupied track section can be automatically set when all track vacancy sections spanned by the virtual track section are cleared. Is z. For example, if the virtual track section C4D is reported to be busy, even though the free reporting sections C and D spanned by it are cleared, the virtual track section C4D can be automatically set. The same is also possible if the virtual track sections B3C and D5E, which at least partially, but completely span, are registered.
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 wer- den, beispielsweise von einem Stellwerk.The particular advantage of the method according to the invention for clearing and occupying track sections is that in the basic position of occupied sections no longer the number of axles of the vehicle axles that passed at the metering points are included, but only the free messages of the sections as provided by the axle counting computers become. The basic position can therefore be carried out by a device outside the axle count, for example by an interlocking.
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 ge- räumten Gleisabschnittes C als Folge einer Störung am Zähl- punkt 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 Zähl- punkte 2, 4 und 9 fahrrichtungsabhangig ein- und ausgefahrenen Achsen null ist.Figure 2 shows the application of the invention to a branching track. The designation of the metering points as well as the real and virtual track sections follow that of FIG. 1. The switch is monitored by a common track section, which is delimited by the metering points 3, 4 and 9. The occupancy message of the track section C, which is assumed to have been completely cleared, remains as a result of a fault on the metering track. point 3, the automatic basic setting of this track section takes place if at least one of the virtual track sections B3C, C4D or C9H is registered, ie e.g. for section B3C, if the number of points depending on the direction of travel 2, 4 and 9 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 metering point of a track vacancy detection area cannot be spanned by a virtual section. H. any counting disturbances occurring there could not easily be rendered ineffective. However, if this were required, it would be possible to achieve this by doubling the entry and exit points concerned, as shown in FIG. 3 for the point of delivery 2 assumed as the entry point of entry. An additional metering point 1 arranged at a short 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 made automatically if the virtual track section B3C were released when the train advanced; however, this basic position message would occur later.
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 each span two 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 can be selected as desired. It is only important that the virtual track sections each span seamlessly adjacent track sections, whereby their arrangement with the point of delivery to be masked can be quite asymmetrical.
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 method according to the invention can be applied to any complex track topologies with switches, sections, crossings etc. without any special precautions by assigning their counting points to the virtual track sections provided for their masking according to the invention.
Der besondere Vorteil des erfindungsgemäßen Verfahrens besteht darin, dass die automatische Grundstellung fehlzahlungsbedingt besetzt gemeldeter Gleisabschnitte allein auf Grund der für die einzelnen realen und virtuellen Gleisab- schnitte 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 of track sections reported due to shortages can be brought about solely on the basis of the vacant messages available for the individual real and virtual track sections, without special measures being taken for this on the counters or the axle counting computers numerical integration of traffic reports is required.
