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 are used to monitor Track sections u.a. Axle counter used. Each axle counter contains one metering point, the two rail contacts and an evaluation unit having. Each axle counter monitors one assigned to it Track section. The axle counter detects a passing car Rail vehicle, the track section is switched busy. Detects the in the direction of travel of the rail vehicle nearest axle counter the passing rail vehicle, the track section is free again connected.
Wird ein Achszähler zur Überwachung zweier oder mehrerer aufeinanderfolgender Gleisabschnitte verwendet, können Störungen an diesem Zählpunkt, z.B. hervorgerufen durch Kabelfehler, 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. Is an axle counter for monitoring two or more consecutive track sections used, may interfere with this point of delivery, e.g. caused by cable fault, to Occupancy report of these track sections and in case of troubleshooting Simultaneous free registration of these track sections lead. This Simultaneous free signals can lead to dangerous operating conditions in the Signaling logic (dissolution circuit) lead.
Aufgabe der Erfindung ist es, die Sicherheit der korrekten Achszählung von Schienenfahrzeugen zu erhöhen.The object of the invention is to ensure the safety of the correct axle counting Rail vehicles increase.
Gelöst wird diese Aufgabe durch ein Verfahren nach Anspruch 1.
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.This object is achieved by a method according to
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, such as 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, for example, the first rail contact is no longer able to detect axles or forward the detected information due to a cable break, only the second rail contact will detect detected axles when the train passes. 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 disorders in which a train itself is on a collision course with another one. Report both Rail contacts detected axes, but corresponds to the time sequence not the expected - e.g. a train became first in front of second Rail contact expected, but the second has triggered before the first -, this is a fault. An interference signal is generated, the corresponding ones 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, when influenced, at least one Rail contact with at least one free, adjacent one Track section generated an interference signal. By means of a metering point, the Occupancy and activation of a track section in the direction of passing train determined. In a chained section is a first metering point provided for a first track section and a second Point of delivery for a subsequent to the first track section second track section. Are now both track sections unlocked and a train is expected, first the first and then the second Track section happens, then usually the first first To detect the counting point of the axles of the train and the first track section and the second counting point becomes the axes of the Detect train and switch the second track section occupied. detected however, the second counting point axes of the train though the first Track section is unlocked, which means that the first metering point no Axes has detected or the forwarding or evaluation of this If the message has not been received correctly, there is a fault. As a result, both track sections are switched busy. One Interference signal is thus generated when axes of a train are detected and at the same time the track section which lies in the direction of the one Train is expected to be unlocked.
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 characterized in particular by that after the fault has been corrected, initially only one track section becomes free again is switched. Thus, not several track sections are released simultaneously connected. And that is the track section in the direction of travel of expected turn first unlocked. For the activation of the upstream track section is a free message by the adjacent Point of delivery provided.
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 with an evaluation and two rail contacts provided. The evaluation unit has a Arithmetic unit, which is programmed in such a way, three different Generate initial states, namely free, occupied and disturbed. Of the Output state free is generated if no influence on the Rail contacts occurs. The initial state occupied is generated, if influencing the rail contacts in the order according to the expected direction of a passing Rail vehicle and / or at least one occupied, adjacent track section occurs. The initial state is disturbed generated when influencing at least one rail contact contrary to 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 metering point is characterized in particular by the fact that the Output state is generated freely, if previously the initial state occupied and from the direction of the passing Rail vehicle adjacent counting point receive a release signal becomes.
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 for processing of signals from at least two points of delivery with two each Rail contacts provided. The arithmetic unit is programmed in such a way generate three different output states for each counting point namely free, occupied and disturbed. The initial state becomes free generated when no influence on the rail contacts occurs, the Initial state occupied, if an influence of the rail contacts in the order according to the expected direction of a passing rail vehicle and / or at least one occupied, adjacent track section occurs and the initial state disturbed when influencing at least one rail contact contrary to the expected direction of a passing Rail vehicle and / or at least one free, adjacent Track section occurs. The arithmetic unit is for example as Microprocessor, digital signal processor or microcontroller executed. It can also be made up of several processors. The Programming is done for example by means of a special Software program in C ++ programming language or by means of at least two software program parts residing on one or more memory can be stored and access to the different processors can have. For example, it is centrally located, e.g. in one electronic interlocking and is designed so the evaluation and / or the generation of the states free, occupied and disturbed for to take over at least two points of delivery. To determine a Condition is disturbed a comparison of the time sequence of the detection of Axes performed by two rail contacts of a metering point. Corresponds to the timing of the detection - e.g. first first Rail contact and shortly thereafter second rail contact - expected - e.g. first before second rail contact due to the direction of travel of the expected, passing train -, so there is no disturbance. Complies the timing of the detection is not the expected, so is one Fault before and the condition is 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 Detection of the axes, but also monitors their number. Detects the first and the second rail contact the same number of axes no disturbance. Is the number different? there is a fault and the condition is disturbed is generated. This is done by software a comparison between the number of detected axes of both rail contacts carried out. This is done e.g. by using two counters. If the counts are correct, taking into account the time delay the detection match, there is no interference. A comparison is made e.g. under Consideration of the direction of travel after a certain period of time, which is advantageously selected depending on the speed of the passing train. If a train is traveling, e.g. with 200 km / h in the direction of the first Rail contact before second rail contact, so a comparison below Considering that axes e.g. not more than 40 meters apart, 0.72 seconds after the last detection by the second Rail contact done.
Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand einer Figur erläutert. Die Figur zeigt zwei Gleisabschnitte.In the following an embodiment of the invention with reference to a Figure explained. The figure shows two track sections.
Es sind drei Zählpunkt 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 of delivery Zp1, Zp2, Zp3 provided. Between Point of delivery Zp1, Zp2, Zp3 are the track sections section 1-2 and section 2-3. Each counting point has two rail contacts Sk1, Sk2 and an evaluation unit evaluation on.
Die Schienenkontakte Sk1, Sk2 dienen zur Detektion von Achsen eines vorbeifahrenden Schienenfahrzeugs, z.B. eines Zuges.The rail contacts Sk1, Sk2 are used to detect the axes 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 mutually on at least one Data line connected for the purpose of exchanging information. To this Information includes e.g. the condition of a track section, e.g. free, occupied, 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 counting point Zp1, Zp2, Zp3 is part of an axle counter and is further Advantageously via at least one data line with a electronic interlocking and the adjacent metering points connected.
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. when Microprocessor, signal processor or microcontroller with special Software is designed.
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 carried out by the electronic interlocking informed about the direction of the expected train. In addition to Direction is the exact time or a period transmitted during which the train is expected at the respective point of delivery. The Evaluation units, as in the embodiment decentralized at the Locating the metering points or centrally, advantageously summarized in an evaluation be arranged 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 metering point report the detected Axes of a passing train of the associated evaluation unit Evaluation. This compares the temporal sequence of the detections with the expected direction of travel of the pre-traveling train and generated at lack of agreement a fault message. This will be the transmitted electronic interlocking. The disturbed condition can only by an operator can be left controlled.
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.For example, would be in sections 1-2 and section 2-3 on free track sections Point of delivery Zp2 an influence on the rail contact Sk1 by a Malfunction occur, track section 1-2 is reported disturbed and Busy busy because this rail contact does not work properly first can be driven and obviously a fault at the point of delivery Zp1 occurred, e.g. caused by an intermittent Core interruption. The track section section 2-3 is also occupied switched, because this state also occurs during a control trip. Will now fixed the fault at the rail contact Sk1 remains track section Section 1-2 in fault condition and track section 2-3 reports again free. Both sections will not be released at the same time. Only when the Fault at meter point Zp1 is corrected, track section becomes section 1-2 released again.
