Definitions
- the invention relates to a method according to the preamble of patent claim 1.
- Axle counting devices are mainly used in railway systems where long distances between train stations have to be bridged or where track construction reasons, e.g. exclude the use of steel sleepers, the use of track circuits.
- a known problem with axle counting devices is the occurrence of counting errors which prevent the free signaling of a track section, which presupposes a tie between the number of axles moved into the track section and the number of axles moved out of the track section, and thus lead to operational inhibitions.
- a number of methods for automatic counting error correction are also known, which enable subsequent release of a track section that has been cleared but is still occupied as a result of a counting error.
- DE-OS 15 30 389 DE-PS 17 80 469 and DE-OS 19 38 311 circuits which compare the counting results of axle counting points with counting results of more distant axle counting points and subsequently release a section of the route reported as occupied due to a counting error if from this comparison it can be concluded that a counting error must exist and a train separation is no longer the reason for the busy signal.
- a second postage reporting level can be formed, for example, by axis reporting points arranged at the beginning and at the end of a route.
- GB-A-2 164 184 discloses a method for track vacancy detection in a railway installation with the features according to the preamble of claim 1.
- the method according to the invention provides for a counting error of an axle counting point to be corrected as a function of the counting result of two further axle counting points, which may be the two closest points of delivery in the direction of travel or the two points of origin immediately behind in the direction of travel.
- a correction is only made if in the first case the result to be corrected is lower than that of the following metering points and in the second case the incorrect result is larger than that of the previous metering points.
- the deviation of the count result to be corrected cannot be caused by a train separation, because in both cases the number of axles has increased, which is only possible through a positive change in train length or through a counting error. If no shunting movements take place in the area under consideration, a positive change in train length is also ruled out as the cause.
- the correction takes place here independently of any signal box information and, since the two "reference points of delivery" always lie directly next to each other on one side of the point of delivery to be corrected, can be carried out as soon as two successive track sections are cleared. If one uses the usual metering point distances and block lengths today, one can hardly speak of an operational disability.
- a further development of the method according to the invention described in claim 2 provides for the marking of the route of a train with the aid of the influenced metering points. This makes it possible to change the route of the train, e.g. through a turnout area, to be held and treated as a line-like route with regard to the correction of counting errors.
- the figures show sequences of meter readings from the metering point memories assigned to the individual metering points, the heights of which are shown here without an exact numerical value, relative to the meter readings of the neighboring axle metering points.
- 2a shows the state of an unused, declared route, the point of reference memory of which all have the same counter readings, e.g. take the counter reading O.
- a correction may only be made if train separation can be excluded with certainty.
- a positive change in train length does not occur in practice, as long as shunting movements can be excluded.
- a correction is permissible if three successive metering points have the constellations shown in FIGS. 1a and 1b.
- the meter reading of the third metering point memory seen from the left to the right in the direction of travel, can immediately be adjusted to the meter reading of the two preceding metering point memories, since it must be based on a positive metering error - excluding positive train length changes. Train separation cannot lead to an increase in the number of axles, so it did not happen here.
- the first point of delivery counted an insufficient number of axes, because both subsequent points of delivery have registered a higher number of counts. A train separation cannot have taken place, since the two points of delivery influenced last have not found any loss in the number of axles.
- Correction may also be made here and the deviating lower counter reading of the first metering point memory may be increased to the meter reading of the two following metering point memories. In contrast to case 1b, in which the correction is carried out immediately, it can only be corrected here if the track section delimited by the following two metering points has cleared.
- the counter reading configurations shown in FIGS. 1c to 1f represent case examples in which a correction was made or omitted using the configurations shown in FIGS. 1a and 1b.
- 1c is the correction of a positive counting error.
- Fig. 1e shows a train separation with a simultaneous counting error. A correction must not be made because it is not clear which of the meter readings (fourth or fifth from the left) is falsified. Neither of the constellations that permit correction (FIG. 1a or 1b) occurs here.
- Fig. 1f shows the case of a train separation with positive counting error, in which the counting error is corrected, but the train separation is documented on the basis of the different meter readings of the metering point memories 3 and 4 (counted from the left), and the track section in between remains occupied.
- the constellation of the counting point memories 4, 5 and 6 is decisive here, which corresponds to the case in FIG. 1b.
- FIG. 2 illustrates a train journey over a route equipped with metering points.
- a train entering the route (Fig. 2a) from the left first increases the count of a point of delivery memory assigned to the first point of delivery, then that of the second, third and so on point of delivery memory (Fig. 2b and 2c).
- the metering point memory located in the direction of travel is deleted, ie reset to the value set before the train journey (FIG. 2d). Since this occurs at every point of delivery on the route traveled, the train journey, as can be seen in FIGS. 2e and 2f, can be followed on the computer until the train has left the route section and all the point of delivery memories have the value set before the train journey.
- each train journey can be documented without the need for signal box information and for this a signal box interface must be created.
- each route can be treated as a simple route by a switch area equipped with metering points. Correction of counting errors can then be carried out without any problems, as described above.
- the counting pulses delivered by the metering points are advantageously stored in separate metering point memories for correction and for marking the route.

Description
Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method according to the preamble of
Achszähleinrichtungen werden in Eisenbahnanlagen vor allem dort eingesetzt, wo große Entfernungen zwischen Bahnhöfen zu überbrücken sind oder wo gleisbauliche Gründe, z.b. die Verwendung von Stahlschwellen, den Einsatz von Gleisstromkreisen ausschließen.Axle counting devices are mainly used in railway systems where long distances between train stations have to be bridged or where track construction reasons, e.g. exclude the use of steel sleepers, the use of track circuits.
Ein bekanntes Problem bei Achszähleinrichtungen ist das Auftreten von Zählfehlern, die die Freimeldung eines Gleisabschnittes, die einen Gleichstand zwischen der Zahl der in den Gleisabschnitt eingefahrenen und der Zahl der aus dem Gleisabschnitt ausgefahrenen Achsen voraussetzt, verhindern und so zu Betriebhemmungen führen.A known problem with axle counting devices is the occurrence of counting errors which prevent the free signaling of a track section, which presupposes a tie between the number of axles moved into the track section and the number of axles moved out of the track section, and thus lead to operational inhibitions.
Es sind auch bereits mehrere Verfahren zur automatischen Zählfehlerkorrektur bekannt, die eine nachträgliche Freimeldung eines an sich freigefahrenen, infolge eines Zählfehlers jedoch weiterhin besetzt gemeldeten Gleisabschnittes ermöglichen.A number of methods for automatic counting error correction are also known, which enable subsequent release of a track section that has been cleared but is still occupied as a result of a counting error.
So sind z.B. in der DE-OS 15 30 389, der DE-PS 17 80 469 und der DE-OS 19 38 311 Schaltungen beschrieben, die Zählergebnisse von Achszählpunkten mit Zählergebnissen weiter entfernt gelegener Achszählpunkte vergleichen und einen infolge eines Zählfehlers besetzt gemeldeten Streckenabschnitt nachträglich freimelden, wenn aus diesem Vergleich geschlossen werden kann, daß ein Zählfehler vorliegen muß und eine Zugtrennung als Grund für die Besetztmeldung ausscheidet.For example, described in DE-OS 15 30 389, DE-PS 17 80 469 and DE-OS 19 38 311 circuits which compare the counting results of axle counting points with counting results of more distant axle counting points and subsequently release a section of the route reported as occupied due to a counting error if from this comparison it can be concluded that a counting error must exist and a train separation is no longer the reason for the busy signal.
Im Zusammenhang mit dem Einsatz von Rechnern zur Zuglenkung ist in einem Aufsatz von A. Delpy und K.H. Suwe in "Signal und Draht" 62 (1970), Heft 4, Seiten 55 ff ein Gleisfreimeldeverfahren beschrieben, das eine Hilfsfreimeldung unter Verwendung einer sogenannten Sollachszahl vorsieht. Die Sollachszahl wird z.B. bei Ausfahrt aus einem Bahnhof ermittelt und begleitet den Zug bis zum nächsten Zielbahnhof. Durch Vergleich von Achszählergebnissen mit der Sollachszahl läßt sich zusätzlich zum direkten Vergleich von an aufeinanderfolgenden Achszählpunkten ermittelten Zählergebnissen feststellen, ob und an welchem Zählpunkt eine Fehlzählung erfolgt ist. Es wird dabei vorausgesetzt, daß von drei Achszählpunkten gleichzeitig nicht mehr als einer einen Zählfehler macht und daß bei einer Zugtrennung nicht gleichzeitig ein Zählfehler an den den besetzt gemeldeten Abschnitt begrenzenden Zählpunkten auftritt, der genau der fehlenden Achszahl entspricht.In connection with the use of computers for train control, an article by A. Delpy and K.H. Suwe in "Signal und Draht" 62 (1970), No. 4, pages 55 ff describes a track vacancy detection method that provides auxiliary vacancy reporting using a so-called target number of axles. The target axis number is e.g. when leaving a station, it detects and accompanies the train to the next destination station. By comparing axle counting results with the target axle number, in addition to the direct comparison of counting results determined at successive axle counting points, it can be determined whether and at which metering point an incorrect counting took place. It is assumed that of three axle counting points no more than one makes a counting error at the same time, and that when the train is separated, a counting error does not occur at the counting points delimiting the section reported as busy, which corresponds exactly to the missing number of axles.
Schließlich ist in einem Aufastz von G. Kampke in "Siemens-Zeitschrift 45 (1971)" Beiheft "Bahntechnik" Seiten 164 ff, auf Seite 166, rechte Spalte, unten, ganz allgemein erwähnt, daß eine selbsttätige Achszählgrundstellung von einer zweiten Freimeldeebene ausgeführt werden kann. Diese zweite Freimeldeebene kann z.B. durch am Anfang und am Ende einer Strecke angeordnete Achsmeldepunkte gebildet werden.Finally, in an article by G. Kampke in "Siemens-Zeitschrift 45 (1971)" Supplement "Bahntechnik", pages 164 ff, on page 166, right column, below, it is mentioned in general that an automatic axle counting basic setting is carried out by a second postage reporting level can. This second free reporting level can be formed, for example, by axis reporting points arranged at the beginning and at the end of a route.
Die beiden zuletzt genannten Verfahren erfordern zusätzliche Einrichtungen in der Außenanlage und im Stellwerk, die, insbesondere dann, wenn bei Einsatz in Weichenbereichen weitere Korrekturbedingungen geprüft werden müssen, recht aufwendig werden. Die Korrektur mittels einer zweiten Freimeldebene hat außerdem den Nachteil, daß erst korrigiert werden kann, wenn die ganze Strecke freigefahren ist. Bei gewünschter dichter Zugfolge stellt diese Zeitverzögerung eine nicht hinnehmbare Betriebsbehinderung dar.The two last-mentioned methods require additional facilities in the outdoor area and in the signal box, which, particularly when additional correction conditions have to be checked when used in switch areas, become quite complex. Correction by means of a second free reporting level also has the disadvantage that it can only be corrected when the entire route has been cleared. If a dense train sequence is desired, this time delay represents an unacceptable operational impediment.
GB-A-2 164 184 offenbart ein Verfahren zur Gleisfreimeldung in einer Eisenbahnanlage mit den Merkmalen gemäß dem Oberbegriff des Anspruchs 1.GB-A-2 164 184 discloses a method for track vacancy detection in a railway installation with the features according to the preamble of
Es ist Aufgabe der Erfindung, ein Gleisfreimeldeverfahren mit Zählfehlerkorrektur der eingangs beschriebenen Art zur Verfügung zu stellen, das bei einfacher Realisierung und ausreichender Sicherheit, im störungsfreien Betrieb keine Beeinträchtigung des Verkehrs und der Stellwerksfunktionen verursacht und das im Störungsfalle auftretende Behinderungen des Verkehrs möglichst gering hält.It is an object of the invention to provide a track vacancy detection method with counting error correction of the type described at the outset which, with simple implementation and sufficient security, does not impair traffic and the interlocking functions in the case of trouble-free operation and which keeps disruptions to traffic in the event of a malfunction as low as possible.
Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of
Das Verfahren nach der Erfindung sieht eine Korrektur eines Zählfehlers eines Achszählpunktes in Abhängigkeit vom Zählergebnis zweier weiterer Achszählpunkte vor, wobei diese die beiden in Fahrtrichtung nächstfolgenden oder die beiden in Fahrtrichtung unmittelbar zurückliegenden Zählpunkte sein können. Dabei erfolgt eine Korrektur nur, wenn im ersten Fall das zu korrigierende Ergebnis niedriger als das der folgenden Zählpunkte und im zweiten Fall das fehlerhafte Ergebnis größer als das der zurückliegenden Zählpunkte ist. In beiden Fällen ist hier sichergestellt, daß die zu korrigierende Abweichung des Zählergebnisses nicht durch eine Zugtrennung hervorgerufen sein kann, denn in beiden Fällen hat sich die Achszahl erhöht, was nur durch positive Zuglängenänderung oder durch einen Zählfehler möglich ist. Finden in dem betrachteten Bereich keine Rangierbewegungen statt, so scheidet auch eine positive Zuglängenänderung als Ursache aus.The method according to the invention provides for a counting error of an axle counting point to be corrected as a function of the counting result of two further axle counting points, which may be the two closest points of delivery in the direction of travel or the two points of origin immediately behind in the direction of travel. A correction is only made if in the first case the result to be corrected is lower than that of the following metering points and in the second case the incorrect result is larger than that of the previous metering points. In both cases it is ensured here that the deviation of the count result to be corrected cannot be caused by a train separation, because in both cases the number of axles has increased, which is only possible through a positive change in train length or through a counting error. If no shunting movements take place in the area under consideration, a positive change in train length is also ruled out as the cause.
Die Korrektur erfolgt hier unabhängig von irgendwelchen Stellwerksinformationen und kann, da die beiden "Referenzzählpunkte" immer unmittelbar nebeneinander auf einer Seite des zu korrigierenden Zählpunktes liegen, bereits vorgenommen werden, sobald zwei aufeinanderfolgende Gleisabschnitte freigefahren sind. Legt man heute übliche Zählpunktabstände und Blocklängen zugrunde, so kann hier kaum noch von Betriebsbehinderung gesprochen werden.The correction takes place here independently of any signal box information and, since the two "reference points of delivery" always lie directly next to each other on one side of the point of delivery to be corrected, can be carried out as soon as two successive track sections are cleared. If one uses the usual metering point distances and block lengths today, one can hardly speak of an operational disability.
Eine in Patentanspruch 2 beschriebene Weiterbildung des Verfahrens nach der Erfindung sieht die Markierung der Fahrstrecke eines Zuges mit Hilfe der beeinflußten Zählpunkte vor. Damit wird es möglich, die Fahrtroute des Zuges, z.B. durch einen Weichenbereich hindurch, festzuhalten und hinsichtlich der Korrektur von Zählfehlern wie eine linienförmige Strecke zu behandeln.A further development of the method according to the invention described in claim 2 provides for the marking of the route of a train with the aid of the influenced metering points. This makes it possible to change the route of the train, e.g. through a turnout area, to be held and treated as a line-like route with regard to the correction of counting errors.
Anhand von zwei Figuren soll nachfolgend das Verfahren nach der Erfindung an einem Ausführungsbeispiel erklärt werden.The method according to the invention is explained below using an exemplary embodiment with reference to two figures.
Die Figuren zeigen Folgen von Zählerständen von den einzelnen Zählpunkten im Rechner zugeordneten Zählpunktspeichern, deren Höhen hier ohne genauen Zahlenwert, relativ zu den Zählerständen der Nachbarachszählpunkte wiedergegeben sind. So gibt Fig. 2a den Zustand einer unbenutzten, freigemeldeten Strecke wieder, deren Zählpunktspeicher alle gleiche Zählerstände, z.B. den Zählerstand O, einnehmen.The figures show sequences of meter readings from the metering point memories assigned to the individual metering points, the heights of which are shown here without an exact numerical value, relative to the meter readings of the neighboring axle metering points. 2a shows the state of an unused, declared route, the point of reference memory of which all have the same counter readings, e.g. take the counter reading O.
Ausgehend von dem in Fig. 2a dargestellten Zustand kann es vorkommen, daß einzelne Zählpunktspeicher einen abweichenden, also höheren oder niedrigeren Zählerstand einnehmen. Ist ein solch abweichender Zählerstand nach Durchfahrt eines Zuges noch vorhanden, so kann es sich um einen positiven oder negativen Zählfehler eines Achszählpunktes handeln oder um eine echte Änderung der Achszahl infolge einer Zugtrennung oder einer positiven Zuglängenänderung.Starting from the state shown in FIG. 2a, it may happen that individual metering point memories assume a different, ie higher or lower, meter reading. If such a different meter reading still exists after a train has passed through, it can be a positive or negative counting error of an axle counting point or a real change in the number of axles as a result of a train separation or a positive change in train length.
Eine Korrektur darf nur erfolgen, wenn eine Zugtrennung mit Sicherheit ausgeschlossen werden kann. Eine positive Zuglängenänderung tritt in der Praxis nicht auf, sofern Rangierbewegungen ausgeschlossen werden können.A correction may only be made if train separation can be excluded with certainty. A positive change in train length does not occur in practice, as long as shunting movements can be excluded.
Eine Korrektur ist zulässig, wenn drei aufeinanderfolgende Zählpunkte die in Fig. 1a und 1b gezeigten Konstellationen aufweisen. Im Falle 1b darf der Zählerstand des in Fahrtrichtung von links nach rechts gesehen, dritten Zählpunktspeichers sofort an den Zählerstand der beiden vorausgehenden Zählpunktspeicher angeglichen werden, da er - positive Zuglängenänderung ausgeschlossen - auf einem positiven Zählfehler beruhen muß. Eine Zugtrennung kann nicht zu einer Zunahme der Achszahl führen, somit hier nicht erfolgt sein. Im Falle 1a hat der erste Zählpunkt eine zu geringe Zahl von Achsen gezählt, denn beide nachfolgenden Zählpunkte haben übereinstimmend eine höhere Anzahl von Zählimpulsen registiert. Eine Zugtrennung kann nicht erfolgt sein, da die beiden zuletzt beeinflußten Zählpunkte keinen Achszahlverlust festgestellt haben. Es darf hier also ebenfalls korrigiert und der abweichende niedrigere Zählerstand des ersten Zählpunktspeichers auf den Zählerstand der beiden folgenden Zählpunktspeicher angehoben werden. Im Gegensatz zum Fall 1b, in dem die Korrektur unverzüglich erfolgt, kann hier jedoch erst korrigiert werden, wenn der durch die nachfolgenden beiden Zählpunkte begrenzte Gleisabschnitt freigefahren ist.A correction is permissible if three successive metering points have the constellations shown in FIGS. 1a and 1b. In case 1b, the meter reading of the third metering point memory, seen from the left to the right in the direction of travel, can immediately be adjusted to the meter reading of the two preceding metering point memories, since it must be based on a positive metering error - excluding positive train length changes. Train separation cannot lead to an increase in the number of axles, so it did not happen here. In case 1a, the first point of delivery counted an insufficient number of axes, because both subsequent points of delivery have registered a higher number of counts. A train separation cannot have taken place, since the two points of delivery influenced last have not found any loss in the number of axles. Correction may also be made here and the deviating lower counter reading of the first metering point memory may be increased to the meter reading of the two following metering point memories. In contrast to case 1b, in which the correction is carried out immediately, it can only be corrected here if the track section delimited by the following two metering points has cleared.
Die in Fig. 1c bis 1f wiedergegebenen Zählerstandskonfigurationen stellen Fallbeispiele dar, bei denen unter Verwendung der in Fig. 1a und 1b wiedergegebenen Konstellationen eine Korrektur durchgeführt oder unterlassen wurde.The counter reading configurations shown in FIGS. 1c to 1f represent case examples in which a correction was made or omitted using the configurations shown in FIGS. 1a and 1b.
In Fig. 1c handelt es sich um die Korrektur eines positiven Zählfehlers. Korrekturentscheidend ist die Konstellation der Zählerstände der drei ersten Zählpunktspeicher, die Fig. 1b entspricht.1c is the correction of a positive counting error. The constellation of the meter readings of the first three metering point memories, which corresponds to FIG. 1b, is decisive for correction.
Fig. 1d gibt einen negativen Zählfehler wieder. Die Korrektur erfolgt hier aufgrund der Konstellation der letzten drei Zählerstände. Diese entspricht der in Fig. 1a wiedergegebenen Konstellation.1d shows a negative counting error. The correction is based on the constellation of the last three meter readings. This corresponds to the constellation shown in Fig. 1a.
Fig. 1e zeigt eine Zugtrennung mit gleichzeitigem Zählfehler. Eine Korrektur darf nicht erfolgen, da nicht klar ist, welcher der Zählerstände (vierter oder fünfter von links) verfälscht ist. Es tritt hier auch keine der eine Korrektur zulassenden Konstellationen (Fig. 1a oder 1b) auf.Fig. 1e shows a train separation with a simultaneous counting error. A correction must not be made because it is not clear which of the meter readings (fourth or fifth from the left) is falsified. Neither of the constellations that permit correction (FIG. 1a or 1b) occurs here.
Fig. 1f, schließlich, zeigt den Fall einer Zugtrennung mit positivem Zählfehler, bei dem der Zählfehler korrigiert wird, die Zugtrennung jedoch anhand der unterschiedlichen Zählerstände der Zählpunktspeicher 3 und 4 (von links gezählt) dokumentiert, und der dazwischenliegende Gleisabschnitt besetzt gemeldet bleibt. Für die Korrektur des Zählfehlers ist hier die Konstellation der Zählpunktspeicher 4, 5 und 6 maßgeblich, die dem Fall der Fig. 1b entspricht.Fig. 1f, finally, shows the case of a train separation with positive counting error, in which the counting error is corrected, but the train separation is documented on the basis of the different meter readings of the
Fig. 2 verdeutlicht eine Zugfahrt über eine mit Zählpunkten ausgerüstete Strecke. Ein Zug, der in die freigemeldete Strecke (Fig. 2a) von links her einfährt, erhöht zuerst den Zählerstand eines dem ersten Zählpunkt zugeordneten Zählpunktspeichers, danach den des zweiten, dritten usw. Zählpunktspeichers (Fig. 2b und 2c). Sobald zwei aufeinanderfolgende Zählpunktspeicher gleiche erhöhte Zählerstände haben (Fig. 2c) wird der in Fahrtrichtung zurückliegende Zählpunktspeicher gelöscht, d.h. auf den vor der Zugfahrt eingestellten Wert zurückgesetzt (Fig. 2d). Da dies bei jedem Zählpunkt der befahrenen Strecke geschieht, kann die Zugfahrt, wie aus Fig. 2e und 2f ersichtlich, am Rechner verfolgt werden, bis der Zug den Streckenabschnitt verlassen hat und alle Zählpunktspeicher wieder den vor der Zugfahrt eingestellten Wert einnehmen.2 illustrates a train journey over a route equipped with metering points. A train entering the route (Fig. 2a) from the left first increases the count of a point of delivery memory assigned to the first point of delivery, then that of the second, third and so on point of delivery memory (Fig. 2b and 2c). As soon as two successive metering point memories have the same increased meter readings (FIG. 2c), the metering point memory located in the direction of travel is deleted, ie reset to the value set before the train journey (FIG. 2d). Since this occurs at every point of delivery on the route traveled, the train journey, as can be seen in FIGS. 2e and 2f, can be followed on the computer until the train has left the route section and all the point of delivery memories have the value set before the train journey.
Werden die beeinflußten und wieder rückgestellten Zählpunkte in einem besonderen Register markiert, so läßt sich jede Zugfahrt dokumentieren, ohne daß hierzu Stellwerksinformation benötigt wird und hierzu eine Stellwerksschnittstelle geschaffen werden muß.If the influenced and reset points of delivery are marked in a special register, each train journey can be documented without the need for signal box information and for this a signal box interface must be created.
Dies ist vor allem dann von großem Vorteil, wenn die Zugfahrt über Weichenbereiche führt und die Fahrtroute dem Rechner zunächst nicht bekannt ist.This is particularly of great advantage if the train journey leads over switch areas and the route is initially unknown to the computer.
Werden die vom Zug beeinflußten Zählpunkte markiert, so läßt sich jede Strecke durch einen mit Zählpunkten ausgerüsteten Weichenbereich wie eine einfache Strecke behandeln. Eine Korrektur von Zählfehlern läßt sich dann, wie oben beschrieben, problemlos durchführen.If the metering points influenced by the train are marked, each route can be treated as a simple route by a switch area equipped with metering points. Correction of counting errors can then be carried out without any problems, as described above.
Die Speicherung der von den Zählpunkten gelieferten Zählimpulse erfolgt zur Korrektur und zur Markierung der Fahrtstrecke zweckmäßig in getrennten Zählpunktspeichern.The counting pulses delivered by the metering points are advantageously stored in separate metering point memories for correction and for marking the route.
