Definitions
- the invention relates to a method for free and busy reporting of track sections.
- Each axle counter includes a metering point, which has two rail contacts and an evaluation unit.
- Each axle counter monitors a track section assigned to it. If the axle counter detects a passing rail vehicle, the track section is switched to occupied. If the axle counter closest to the direction of travel of the rail vehicle detects the passing rail vehicle, the track section is released again.
- an interference signal is generated when at least one rail contact is influenced against the expected direction of a passing rail vehicle and / or at least one free, adjacent track section.
- One metering point has two rail contacts. Depending on the direction of the passing rail vehicle, first one rail contact and then the other rail contact will detect axles of the passing rail vehicle.
- the invention combines the evaluation of the detected axes by the rail contacts with the expected direction of the passing rail vehicle, e.g. a train. If, for example, a train is expected to pass first the first and then the second rail contact, the first rail contact first detects an axis of the train and then the second rail contact after a correctly functioning metering point. If it is now e.g.
- the first rail contact due to a cable break is no longer able to detect axes or forward the detected information, so when passing the train only the second rail contact will detect detected axes.
- the combination with the expected direction of the passing train shows that a fault has occurred.
- Trigger for the detection by the second, but not by the first rail contact is a non-functioning first rail contact. This fault must be remedied. This happens, for example, by a fitter who exchanges the rail contact on site. In addition, both track sections adjoining the rail contact are switched to occupied. As a result, faults are detected quickly.
- both rail contacts detect detected axes, but does not correspond to the time sequence of the expected - for example, was a train in the direction of first before second Rail contact expected, but the second has triggered before the first - so there is a fault.
- An interference signal is generated, the corresponding track sections are blocked by occupancy.
- an interference signal is generated when at least one rail contact is influenced by at least one free, adjacent track section.
- a metering point By means of a metering point, the occupancy and activation of a track section in the direction of the passing train is determined.
- a first metering point is provided for a first track section and a second metering point for a second track section adjoining the first track section.
- the method according to the invention is distinguished, in particular, by the fact that, after the fault has been remedied, initially only one track section is released again. Thus, not several track sections are enabled simultaneously. Namely, the track section is initially released in the direction of travel of the expected train. For the activation of the upstream track section a free message is provided by the adjacent metering point.
- an inventive metering point is provided with an evaluation unit and two rail contacts.
- the evaluation unit has a Arithmetic unit, which is programmed to produce three different output states, namely free, occupied and disturbed.
- the output state free is generated if no influence on the rail contacts occurs.
- the initial state occupied is generated when an influence of the rail contacts occurs in the order corresponding to the expected direction of a passing rail vehicle and / or at least one occupied adjacent track section.
- the initial state is disturbed is generated when an influence of at least one rail contact against the expected direction of a passing rail vehicle and / or at least one free, adjacent track section occurs.
- the point of delivery is characterized in particular by the fact that the initial state is generated freely if the initial state was previously occupied and an enable signal is received by the point of delivery adjacent to the passing rail vehicle.
- an arithmetic unit for processing signals from at least two points of delivery, each with two rail contacts.
- the arithmetic unit is programmed to generate three different output states for each counting point, namely free, occupied and disturbed.
- the output state is generated free, if no influence on the rail contacts occurs, the output state occupies when an influence of the rail contacts in the order corresponding to the expected direction of a passing rail vehicle and / or at least one occupied, adjacent track section occurs and disturbed the initial state, if an influence of at least one rail contact against the expected direction of a passing rail vehicle and / or at least one free, adjacent track section occurs.
- the arithmetic unit is designed, for example, as a microprocessor, digital signal processor or microcontroller.
- the Programming takes place, for example, by means of a special software program in C ++ programming language or by means of at least two software program components which can be stored on one or more memories and to which different processors can have access. It is for example arranged centrally, for example in an electronic interlocking and is designed to take over the evaluation and / or the generation of the states free, occupied and disturbed for at least two points of delivery. To determine a condition disturbed, a comparison of the time sequence of the detection of axes by two rail contacts of a counting point is performed.
- not only the time sequence of the detection of the axes, but also their number is monitored. If the first and the second rail contact detect the same number of axes, there is no interference. Is the number different? If there is a fault and the condition is disturbed, it is generated.
- a comparison is made between the number of detected axes of both rail contacts. This is done, for example, by using two counters. If the counter readings coincide, taking into account the time delay in the detection, there is no disturbance.
- a comparison is made, for example, taking into account the direction of travel after a certain period of time, which is advantageously selected depending on the speed of the passing train.
- a comparison may be made 0.72 seconds after the last detection by the second rail contact, taking into account that axles are for example at most 40 meters apart.
- FIG. 1 shows two track sections.
- Each metering point has two rail contacts Sk1, Sk2 and an evaluation unit evaluation.
- the rail contacts Sk1, Sk2 serve to detect axles of a passing rail vehicle, e.g. a train.
- the evaluation evaluation units are interconnected via at least one data line for the purpose of exchanging information.
- This information includes e.g. the condition of a track section, e.g. free, busy, disturbed.
- Each point of delivery Zp1, Zp2, Zp3 is part of an axle counter and is also advantageously connected via at least one data line with an electronic interlocking and the adjacent points of delivery.
- Each evaluation unit evaluation has an arithmetic unit, which, e.g. is designed as a microprocessor, signal processor or microcontroller with special software.
- Each evaluation unit evaluation is informed by the electronic interlocking about the direction of the train to be expected. In addition to the direction, the exact time or period during which the train is expected at the respective point of delivery is transmitted. As in the exemplary embodiment, the evaluation units can be arranged decentrally at the locations of the points of delivery or centrally, advantageously combined in an evaluation unit in the electronic interlocking.
- the rail contacts Sk1, Sk2 of a counting point report the detected axes of a passing train of the associated evaluation unit Evaluation. This compares the time sequence of the detections with the expected direction of travel of the pre-traveling train and generates a fault message if there is no match. This is transmitted to the electronic interlocking.
- the faulty state can only be left controlled by an operator.
- track section is 1-2 reported disturbed and busy, because this rail contact can not be properly driven first and obviously a fault has occurred at the point of delivery Zp1, eg caused by an intermittent wire interruption.
- the track section section 2-3 is also switched busy, as this state also occurs during a control travel. If the fault on the rail contact Sk1 is now rectified, track section section 1-2 remains in the fault state and track section 2-3 signals again. Both sections will not be released at the same time. Only when the fault is corrected at the point of delivery Zp1 will track section 1-2 be released again.

Abstract
Description
Die Erfindung betrifft ein Verfahren zur Frei- und Belegtmeldung von Gleisabschnitten.The invention relates to a method for free and busy reporting of track sections.
In der Eisenbahnsignaltechnik werden zur Überwachung von Gleisabschnitten u.a. Achszähler eingesetzt. Jeder Achszähler beinhaltet einen Zählpunkt, der zwei Schienenkontakte und eine Auswerteeinheit aufweist. Jeder Achszähler überwacht einen ihm zugewiesenen Gleisabschnitt. Detektiert der Achszähler ein vorbeifahrendes Schienenfahrzeug, wird der Gleisabschnitt belegt geschaltet. Detektiert der in Fahrtrichtung des Schienenfahrzeugs nächstgelegene Achszähler das vorbeifahrende Schienenfahrzeug, wird der Gleisabschnitt wieder frei geschaltet.In railway signaling, the monitoring of track sections u.a. Axle counter used. Each axle counter includes a metering point, which has two rail contacts and an evaluation unit. Each axle counter monitors a track section assigned to it. If the axle counter detects a passing rail vehicle, the track section is switched to occupied. If the axle counter closest to the direction of travel of the rail vehicle detects the passing rail vehicle, the track section is released again.
Wird ein Achszähler zur Überwachung zweier oder mehrerer aufeinanderfolgender Gleisabschnitte verwendet, können Störungen an diesem Zählpunkt, z.B. hervorgerufen durch Kobelfehler, zur Belegtmeldung dieser Gleisabschnitte und bei Störungsbeseitigung zur gleichzeitigen Freimeldung dieser Gleisabschnitte führen. Dieses gleichzeitige Freimelden kann zu gefährlichen Betriebszuständen in der Stellwerkslogik (Auflöseschaltung) führen.If an axle counter is used to monitor two or more consecutive track sections, faults at that point of delivery, e.g. caused by Kobelfehler, lead to occupancy of these track sections and fault clearance for simultaneous clearing of these track sections. This simultaneous free signaling can lead to dangerous operating states in the interlocking logic (resolution circuit).
Aus der Eg1101684 ist ein Verfahren bekannt, bei dem jedoch eine Meldung der Achszahl in beiden Richtungen abgegeben wird, wenn die Fahrtrichtung nicht eindeutig bestimmt werden kann. Es wird auch kein Signal generiert. Aufgabe der Erfindung ist es, die Sicherheit der korrekten Achszählung von Schienenfahrzeugen zu erhöhen.From Eg1101684 a method is known in which, however, a message of the number of axles is issued in both directions, if the direction of travel can not be determined uniquely. There is no signal generated. The object of the invention is to increase the safety of the correct axle counting of rail vehicles.
Gelöst wird diese Aufgabe durch ein Verfahren nach Anspruch 1.This object is achieved by a method according to
Beim erfindungsgemäßen Verfahren zur Frei- und Belegtmeldung von Gleisabschnitten wird bei einer Beeinflussung mindestens eines Schienenkontakts entgegen der zu erwartenden Richtung eines vorbeifahrenden Schienenfahrzeugs und/oder bei mindestens einem freien, angrenzenden Gleisabschnitt ein Störsignal generiert. Ein Zählpunkt weist zwei Schienenkontakte auf. Je nach Richtung des vorbeifahrenden Schienenfahrzeugs wird zunächst der eine Schienenkontakt und danach der andere Schienenkontakt Achsen des vorbeifahrenden Schienenfahrzeugs detektieren. Die Erfindung verbindet die Auswertung der detektierten Achsen durch die Schienenkontakte mit der zu erwartenden Richtung des vorbeifahrenden Schienenfahrzeugs, z.B. eines Zuges. Wird beispielsweise eine Zug erwartet, der zunächst den ersten und danach den zweiten Schienenkontakt passiert, so detektiert bei einem korrekt funktionierenden Zählpunkt zunächst der erste Schienenkontakt eine Achse des Zuges und zeitlich danach der zweite Schienenkontakt. Ist nun z.B. der erste Schienenkontakt auf Grund eines Kabelbruchs nicht mehr in der Lage Achsen zu detektieren bzw. die detektierte Information weiterzuleiten, so wird bei Passieren des Zuges nur der zweite Schienenkontakt detektierte Achsen melden. Aus der Kombination mit der zu erwarteten Richtung des vorbeifahrenden Zuges ergibt sich, dass eine Störung aufgetreten ist. Auslöser für die Detektion durch den zweiten, nicht aber durch den ersten Schienenkontakt ist ein nicht funktionierender ersten Schienenkontakt. Diese Störung muss behoben werden. Dies geschieht beispielsweise durch einen Monteur, der vor Ort den Schienenkontakt auswechselt. Zusätzlich werden beide an den Schienenkontakt angrenzenden Gleisabschnitte belegt geschaltet. Dadurch werden Störungen schnell erkannt.In the method according to the invention for free and busy reporting of track sections, an interference signal is generated when at least one rail contact is influenced against the expected direction of a passing rail vehicle and / or at least one free, adjacent track section. One metering point has two rail contacts. Depending on the direction of the passing rail vehicle, first one rail contact and then the other rail contact will detect axles of the passing rail vehicle. The invention combines the evaluation of the detected axes by the rail contacts with the expected direction of the passing rail vehicle, e.g. a train. If, for example, a train is expected to pass first the first and then the second rail contact, the first rail contact first detects an axis of the train and then the second rail contact after a correctly functioning metering point. If it is now e.g. the first rail contact due to a cable break is no longer able to detect axes or forward the detected information, so when passing the train only the second rail contact will detect detected axes. The combination with the expected direction of the passing train shows that a fault has occurred. Trigger for the detection by the second, but not by the first rail contact is a non-functioning first rail contact. This fault must be remedied. This happens, for example, by a fitter who exchanges the rail contact on site. In addition, both track sections adjoining the rail contact are switched to occupied. As a result, faults are detected quickly.
Es können auch solche Störungen erkannt werden, bei denen ein Zug sich auf Kollisionskurs mit einem anderen befindet. Melden zwar beide Schienenkontakte detektierte Achsen, entspricht aber die zeitliche Abfolge nicht der erwarteten - z.B. wurde ein Zug in Richtung erster vor zweiter Schienenkontakt erwartet, der zweite hat aber vor dem ersten ausgelöst -, so liegt eine Störung vor. Ein Störsignal wird generiert, die entsprechenden Gleisabschnitte werden durch Belegung gesperrt.It can also be detected such disturbances, in which a train is on a collision course with another. Although both rail contacts detect detected axes, but does not correspond to the time sequence of the expected - for example, was a train in the direction of first before second Rail contact expected, but the second has triggered before the first - so there is a fault. An interference signal is generated, the corresponding track sections are blocked by occupancy.
Alternativ oder zusätzlich wird bei einer Beeinflussung mindestens eines Schienenkontakts bei mindestens einem freien, angrenzenden Gleisabschnitt ein Störsignal generiert. Mittels eines Zählpunkts wird die Belegung und Freischaltung eines Gleisabschnitts in Richtung des vorbeifahrenden Zuges bestimmt. Bei einem verketteten Abschnitt ist ein erster Zählpunkt vorgesehen für einen ersten Gleisabschnitt und ein zweiter Zählpunkt für einen sich an den ersten Gleisabschnitt anschließenden zweiten Gleisabschnitt. Sind nun beide Gleisabschnitte freigeschaltet und wird ein Zug erwartet, der zunächst den ersten und dann den zweiten Gleisabschnitt passiert, dann wird im Normalfall zunächst der erste Zählpunkt Achsen des Zuges detektieren und den ersten Gleisabschnitt belegt schalten und zeitlich danach wird der zweite Zählpunkt Achsen des Zuges detektieren und den zweiten Gleisabschnitt belegt schalten. Detektiert jedoch der zweite Zählpunkt Achsen des Zuges obwohl der erste Gleisabschnitt freigeschaltet ist, was bedeutet das der erste Zählpunkt keine Achsen detektiert hat oder die Weiterleitung oder Auswertung dieser Meldung nicht ordnungsgemäß erfolgt ist, liegt eine Störung vor. Infolgedessen werden beide Gleisabschnitte belegt geschaltet. Ein Störsignal wird somit generiert, wenn Achsen eines Zuges detektiert werden und gleichzeitig der Gleisabschnitt, welcher in der Richtung liegt aus der ein Zug erwartet wird, frei geschaltet ist.Alternatively or additionally, an interference signal is generated when at least one rail contact is influenced by at least one free, adjacent track section. By means of a metering point, the occupancy and activation of a track section in the direction of the passing train is determined. In a linked section, a first metering point is provided for a first track section and a second metering point for a second track section adjoining the first track section. Now, if both track sections are unlocked and a train is expected, the first passes first and then the second track section, then normally the first counting point axes of the train will detect and switch the first track section occupied and temporally thereafter, the second counting point axes of the train detect and switch the second track section occupied. However, if the second counting point axes of the train detects that the first track section has been cleared, which means that the first counting point has not detected any axes or the forwarding or evaluation of this message has not been carried out correctly, there is a fault. As a result, both track sections are switched busy. An interference signal is thus generated when axes of a train are detected and at the same time the track section, which is in the direction from which a train is expected, is enabled.
Das erfindungsgemäße Verfahren zeichnet sich insbesondere dadurch aus, dass nach behobener Störung zunächst nur ein Gleisabschnitt wieder frei geschaltet wird. Somit werden nicht mehrere Gleisabschnitte gleichzeitig frei geschaltet. Und zwar wird der Gleisabschnitt in Fahrtrichtung des erwarteten Zuges zunächst freigeschaltet. Für die Freischaltung des vorgelagerten Gleisabschnitts ist eine Freimeldung durch den benachbarten Zählpunkt vorgesehen.The method according to the invention is distinguished, in particular, by the fact that, after the fault has been remedied, initially only one track section is released again. Thus, not several track sections are enabled simultaneously. Namely, the track section is initially released in the direction of travel of the expected train. For the activation of the upstream track section a free message is provided by the adjacent metering point.
Ferner ist ein erfindungsgemäßer Zählpunkt mit einer Auswerteeinheit und zwei Schienenkontakten vorgesehen. Die Auswerteeinheit weist eine Recheneinheit auf, die derart programmiert ist, drei unterschiedlichen Ausgangszustände zu erzeugen, namentlich frei, belegt und gestört. Der Ausgangszustand frei wird generiert, wenn keine Beeinflussung an den Schienenkontakten auftritt. Der Ausgangszustand belegt wird generiert, wenn eine Beeinflussung der Schienenkontakte in der Reihenfolge entsprechend der zu erwartenden Richtung eines vorbeifahrenden Schienenfahrzeugs und/oder bei mindestens einem belegten, angrenzenden Gleisabschnitt auftritt. Der Ausgangszustand gestört wird generiert, wenn eine Beeinflussung mindestens eines Schienenkontakts entgegen der zu erwartenden Richtung eines vorbeifahrenden Schienenfahrzeugs und/oder bei mindestens einem freien, angrenzenden Gleisabschnitt auftritt.Furthermore, an inventive metering point is provided with an evaluation unit and two rail contacts. The evaluation unit has a Arithmetic unit, which is programmed to produce three different output states, namely free, occupied and disturbed. The output state free is generated if no influence on the rail contacts occurs. The initial state occupied is generated when an influence of the rail contacts occurs in the order corresponding to the expected direction of a passing rail vehicle and / or at least one occupied adjacent track section. The initial state is disturbed is generated when an influence of at least one rail contact against the expected direction of a passing rail vehicle and / or at least one free, adjacent track section occurs.
Der Zählpunkt zeichnet sich insbesondere dadurch aus, dass der Ausgangszustand frei generiert wird, wenn zuvor der Ausgangszustand belegt vorlag und von dem in Richtung des vorbeifahrenden Schienenfahrzeugs benachbarten Zählpunkt ein Freigabesignal empfangen wird.The point of delivery is characterized in particular by the fact that the initial state is generated freely if the initial state was previously occupied and an enable signal is received by the point of delivery adjacent to the passing rail vehicle.
Des weiteren ist eine erfindungsgemäße Recheneinheit zur Verarbeitung von Signalen von mindestens zwei Zählpunkten mit jeweils zwei Schienenkontakten vorgesehen. Die Recheneinheit ist derart programmiert, für jeden Zählpunkt drei unterschiedliche Ausgangszustände zu erzeugen, namentlich frei, belegt und gestört. Der Ausgangszustand frei wird generiert, wenn keine Beeinflussung an den Schienenkontakten auftritt, der Ausgangszustand belegt, wenn eine Beeinflussung der Schienenkontakte in der Reihenfolge entsprechend der zu erwartenden Richtung eines vorbeifahrenden Schienenfahrzeugs und/oder bei mindestens einem belegten, angrenzenden Gleisabschnitt auftritt und der Ausgangszustand gestört, wenn eine Beeinflussung mindestens eines Schienenkontakts entgegen der zu erwartenden Richtung eines vorbeifahrenden Schienenfahrzeugs und/oder bei mindestens einem freien, angrenzenden Gleisabschnitt auftritt. Die Recheneinheit ist beispielsweise als Mikroprozessor, Digitaler Signalprozessor oder Mikrokontroller ausgeführt. Sie kann auch aus mehreren Prozessoren aufgebaut sein. Die Programmierung erfolgt beispielsweise mittels eines speziellen Softwareprogramms in Programmiersprache C++ oder mittels mindestens zwei Softwareprogrammmteilen, die auf einem oder mehreren Speicher abgespeichert sein können und auf die unterschiedliche Prozessoren Zugriff haben können. Sie ist beispielsweise zentral angeordnet, z.B. in einem elektronischen Stellwerk und ist derart ausgebildet, die Auswertung und/oder die Generierung der Zustände frei, belegt und gestört für mindestens zwei Zählpunkte zu übernehmen. Zur Feststellung eines Zustands gestört wird ein Vergleich der zeitlichen Abfolge der Detektion von Achsen durch zwei Schienenkontakte eines Zählpunkts durchgeführt. Entspricht die zeitliche Abfolge der Detektion - z.B. zunächst erster Schienenkontakt und kurz darauf zweiter Schienenkontakt -, der erwarteten - z.B. erster vor zweiter Schienenkontakt auf Grund der Fahrtrichtung des erwarteten, vorbeifahrenden Zuges -, so liegt keine Störung vor. Entspricht die zeitliche Abfolge der Detektion nicht der erwarteten, so liegt eine Störung vor und der Zustand gestört wird generiert.Furthermore, an arithmetic unit according to the invention is provided for processing signals from at least two points of delivery, each with two rail contacts. The arithmetic unit is programmed to generate three different output states for each counting point, namely free, occupied and disturbed. The output state is generated free, if no influence on the rail contacts occurs, the output state occupies when an influence of the rail contacts in the order corresponding to the expected direction of a passing rail vehicle and / or at least one occupied, adjacent track section occurs and disturbed the initial state, if an influence of at least one rail contact against the expected direction of a passing rail vehicle and / or at least one free, adjacent track section occurs. The arithmetic unit is designed, for example, as a microprocessor, digital signal processor or microcontroller. It can also be made up of several processors. The Programming takes place, for example, by means of a special software program in C ++ programming language or by means of at least two software program components which can be stored on one or more memories and to which different processors can have access. It is for example arranged centrally, for example in an electronic interlocking and is designed to take over the evaluation and / or the generation of the states free, occupied and disturbed for at least two points of delivery. To determine a condition disturbed, a comparison of the time sequence of the detection of axes by two rail contacts of a counting point is performed. Corresponds to the timing of the detection - for example, first first rail contact and shortly after the second rail contact - the expected - eg first before second rail contact due to the direction of the expected, passing train -, so there is no disturbance. If the time sequence of the detection does not correspond to the expected one, there is a fault and the state of being disturbed is generated.
Bei einer vorteilhaften Ausgestaltung wird nicht nur die zeitliche Abfolge der Detektion der Achsen, sondern auch ihre Anzahl überwacht. Detektiert der ersten und der zweite Schienenkontakt dieselbe Anzahl von Achsen liegt keine Störung vor. Unterscheidet sich die Anzahl. liegt eine Störung vor und der Zustand gestört wird generiert. Dazu wird mittels Software ein vergleich zwischen der Anzahl der detektierten Achsen beider Schienenkontakte durchgeführt. Dies erfolgt z.B. durch Verwendung von zwei Zählern. Stimmen die Zählerstände unter Berücksichtigung des zeitlichen Verzugs bei der Detektion überein, liegt keine Störung vor. Ein Vergleich wird z.B. unter Berücksichtigung der Fahrtrichtung nach Ablauf einer gewissen Zeitspanne, die vorteilhafterweise abhängig gewählt ist von der Geschwindigkeit des vorbeifahrenden Zuges. Fährt ein Zug z.B. mit 200 km/h in Richtung erster Schienenkontakt vor zweitem Schienenkontakt, so kann ein Vergleich unter Berücksichtigung, dass Achsen z.B. maximal 40 Meter auseinander liegen, 0,72 Sekunden nach der letzten Detektion durch den zweiten Schienenkontakt erfolgen.In an advantageous embodiment, not only the time sequence of the detection of the axes, but also their number is monitored. If the first and the second rail contact detect the same number of axes, there is no interference. Is the number different? If there is a fault and the condition is disturbed, it is generated. For this purpose, by means of software, a comparison is made between the number of detected axes of both rail contacts. This is done, for example, by using two counters. If the counter readings coincide, taking into account the time delay in the detection, there is no disturbance. A comparison is made, for example, taking into account the direction of travel after a certain period of time, which is advantageously selected depending on the speed of the passing train. For example, if a train is traveling at 200 km / h in the direction of the first rail contact before the second rail contact, a comparison may be made 0.72 seconds after the last detection by the second rail contact, taking into account that axles are for example at most 40 meters apart.
Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand einer Figur erläutert. Die Figur zeigt zwei Gleisabschnitte.In the following an embodiment of the invention will be explained with reference to a figure. The figure shows two track sections.
Es sind drei Zählpunkte Zp1, Zp2, Zp3 vorgesehen. Zwischen den Zählpunkten Zp1, Zp2, Zp3 befinden sich die Gleisabschnitte Abschnitt 1-2 und Abschnitt 2-3. Jeder Zählpunkt weist zwei Schienenkontakte Sk1, Sk2 und eine Auswerteeinheit Auswertung auf.There are three points Zp1, Zp2, Zp3 provided. Between track points Zp1, Zp2, Zp3 are the track sections section 1-2 and section 2-3. Each metering point has two rail contacts Sk1, Sk2 and an evaluation unit evaluation.
Die Schienenkontakte Sk1, Sk2 dienen zur Detektion von Achsen eines vorbeifahrenden Schienenfahrzeugs, z.B. eines Zuges.The rail contacts Sk1, Sk2 serve to detect axles of a passing rail vehicle, e.g. a train.
Die Auswerteeinheiten Auswertung sind untereinander über mindestens eine Datenleitung verbunden zwecks Austausch von Informationen. Zu diesen Informationen zählen z.B. der Zustand eines Gleisabschnitts, z.B. frei, belegt, gestört.The evaluation evaluation units are interconnected via at least one data line for the purpose of exchanging information. This information includes e.g. the condition of a track section, e.g. free, busy, disturbed.
Jeder Zählpunkt Zp1, Zp2, Zp3 ist Teil eines Achszählers und ist ferner vorteilhafterweise über mindestens eine Datenleitung mit einem elektronischen Stellwerk und den benachbarten Zählpunkten verbunden.Each point of delivery Zp1, Zp2, Zp3 is part of an axle counter and is also advantageously connected via at least one data line with an electronic interlocking and the adjacent points of delivery.
Jede Auswerteeinheit Auswertung weist eine Recheneinheit auf, die z.B. als Mikroprozessor, Signalprozessor oder Mikrokontroller mit spezieller Software ausgestaltet ist.Each evaluation unit evaluation has an arithmetic unit, which, e.g. is designed as a microprocessor, signal processor or microcontroller with special software.
Jede Auswerteeinheit Auswertung wird durch das elektronische Stellwerk über die Richtung des zu erwartenden Zuges informiert. Zusätzlich zur Richtung wird der genaue Zeitpunkt bzw. eine Zeitspanne übermittelt, während derer der Zug am jeweiligen Zählpunkt erwartet wird. Die Auswerteeinheiten können wie im Ausführungsbeispiel dezentral an der Orten der Zählpunkte oder zentral, vorteilhafterweise zusammengefasst in einer Auswerteeinheit im elektronischen Stellwerk angeordnet sein.Each evaluation unit evaluation is informed by the electronic interlocking about the direction of the train to be expected. In addition to the direction, the exact time or period during which the train is expected at the respective point of delivery is transmitted. As in the exemplary embodiment, the evaluation units can be arranged decentrally at the locations of the points of delivery or centrally, advantageously combined in an evaluation unit in the electronic interlocking.
Die Schienenkontakte Sk1, Sk2 eines Zählpunkts melden die detektierten Achsen eines vorbeifahrenden Zuges der zugehörigen Auswerteeinheit Auswertung. Diese vergleicht die zeitliche Abfolge der Detektionen mit der erwarteten Fahrtrichtung des vorbefahrenden Zuges und generiert bei mangelnder Übereinstimmung eine Störungsmeldung. Diese wird dem elektronischen Stellwerk übermittelt. Der gestörte Zustand kann nur durch eine Bedienung kontrolliert verlassen werden.The rail contacts Sk1, Sk2 of a counting point report the detected axes of a passing train of the associated evaluation unit Evaluation. This compares the time sequence of the detections with the expected direction of travel of the pre-traveling train and generates a fault message if there is no match. This is transmitted to the electronic interlocking. The faulty state can only be left controlled by an operator.
Würde etwa bei freien Gleisabschnitten Abschnitt 1-2 und Abschnitt 2-3 am Zählpunkt Zp2 eine Beeinflussung am Schienenkontakt Sk1 durch eine Störung auftreten, wird Gleisabschnitt Abschnitt 1-2 gestört gemeldet und belegt geschaltet, da dieser Schienenkontakt ordnungsgemäß nicht zuerst befahren werden kann und offensichtlich eine Störung am Zählpunkt Zp1 aufgetreten ist, z.B. verursacht durch eine intermittierende Aderunterbrechung. Der Gleisabschnitt Abschnitt 2-3 wird ebenfalls belegt geschaltet, da dieser Zustand auch bei einer Regelfahrt auftritt. Wird nun die Störung am Schienenkontakt Sk1 behoben, bleibt Gleisabschnitt Abschnitt 1-2 im Störungszustand und Gleisabschnitt 2-3 meldet wieder frei. Beide Abschnitte werden nicht mehr gleichzeitig frei. Erst wenn die Störung am Zählpunkt Zp1 behoben wird, wird Gleisabschnitt Abschnitt 1-2 wieder frei geschaltet.Would occur at free track sections Section 1-2 and section 2-3 at the point Zp2 influencing the rail contact Sk1 by a fault, track section is 1-2 reported disturbed and busy, because this rail contact can not be properly driven first and obviously a fault has occurred at the point of delivery Zp1, eg caused by an intermittent wire interruption. The track section section 2-3 is also switched busy, as this state also occurs during a control travel. If the fault on the rail contact Sk1 is now rectified, track section section 1-2 remains in the fault state and track section 2-3 signals again. Both sections will not be released at the same time. Only when the fault is corrected at the point of delivery Zp1 will track section 1-2 be released again.
Claims (4)
- Method for signalling track sections free and occupied, in which, in the event of influencing of at least one rail contact of a counting point opposite to the direction to be expected of a passing rail vehicle, and in the event of at least one free, adjacent track section opposite to the direction of travel, both track sections adjoining the contact point are switched to occupied and a fault signal is generated, only the adjacent track section in the direction of travel being switched free again initially once the fault has been rectified.
- Counting point with an evaluation unit and two rail contacts, in which the evaluation unit has an arithmetic unit, which is programmed so as to generate three different initial states, the initial state free being generated if no influencing occurs at the rail contacts, the initial state occupied if influencing of the rail contacts occurs in the sequence corresponding to the direction to be expected of a passing rail vehicle and in the event of at least one occupied, adjacent track section and the initial state faulty if influencing of at least one rail contact occurs opposite to the direction to be expected of a passing rail vehicle and in the event of at least one free, adjacent track section, the arithmetic unit only switching the adjacent track section in the direction of travel free again initially once the fault has been rectified.
- Counting point according to claim 2, characterized in that the initial state free is generated if previously the state occupied existed and a release signal is received from the neighbouring counting point in the direction of the passing rail vehicle.
- Arithmetic unit for processing signals from at least two counting points, with two rail contacts respectively, separated by track sections, which unit is programmed so as to generate three different initial states for each counting point, the initial state free being generated if no influencing occurs at the rail contacts, the initial state occupied if influencing of the rail contacts occurs in the sequence corresponding to the direction to be expected of a passing rail vehicle and in the event of at least one occupied, adjacent track section and the initial state faulty if influencing of at least one rail contact occurs opposite to the direction to be expected of a passing rail vehicle and in the event of at least one free, adjacent track section, the arithmetic unit only switching the adjacent track section in the direction of travel free again initially once the fault has been rectified.
