Description
Die Erfindung betrifft ein Verfahren zur Erhöhung der Verfügbarkeit einer Raderkennungseinrichtung mit einem Achszählsensor zur Erfassung der ein Gleis überfahrenden Räder eines Schienenfahrzeuges, insbesondere für eine Gleisfreimeldeanlage, sowie eine diesbezügliche Raderkennungseinrichtung.The invention relates to a method for increasing the availability of a wheel detection device with an axle counting sensor for detecting the wheels of a rail vehicle passing over a track, in particular for a train detection system, as well as a corresponding wheel recognition device.
Achszählsensoren werden im Bahnwesen für die Gleisfreimeldung, aber auch für andere Schalt- und Meldeaufgaben eingesetzt. Dabei wird überwiegend die magnetfeldbeeinflussende Wirkung der Eisenräder des Schienenfahrzeuges ausgenutzt. Mittels am Gleiskörper angebrachter induktiver Sensoren, die ein spezifisches Magnetfeld erzeugen, lässt sich die Rückwirkung der Eisenräder erfassen, wobei mit jeder Raderfassung ein Radimpuls registriert wird. Die Anzahl der Radimpulse gibt im Zusammenwirken mit einem weiteren Radsensor Auskunft über den Belegungszustand des dazwischenliegenden Gleisabschnittes. Diese Gleisfreimeldung stellt ein wesentliches Entscheidungskriterium für die Steuerung von Weichen und Signalen dar. Anhand des Belegungszustandes von Gleisabschnitten wird die Entscheidung getroffen, ob ein Schienenfahrzeug in diesen Gleisabschnitt einfahren darf oder nicht. Folglich müssen Achszählsensoren extrem hohen Zuverlässigkeitsanforderungen genügen.Axle counting sensors are used in the railway industry for track vacancy detection, but also for other switching and reporting tasks. In this case, the magnetic field influencing effect of the iron wheels of the rail vehicle is predominantly utilized. By means of inductive sensors mounted on the track, which generate a specific magnetic field, the retroactivity of the iron wheels can be detected, with each wheel detection registering a wheel pulse. The number of wheel pulses in conjunction with another wheel sensor provides information about the occupancy state of the intermediate track section. This track vacancy is an essential decision criterion for the control of switches and signals. Based on the occupancy state of track sections, the decision is made whether a rail vehicle may enter this track section or not. Consequently, axle counting sensors must meet extremely high reliability requirements.
In der
In ihrer Einsatzumgebung sind Achszählsensoren jedoch zahlreichen Störeinflüssen ausgesetzt. Um Fehlzählungen auszuschließen oder deren Wahrscheinlichkeit zumindest zu verringern, sind verschiedene Algorithmen und Anordnungen bekannt, die eine Plausibilisierung der Zählungen ermöglichen. Beispielsweise kann die Verfügbarkeit bei Störungen und Ausfällen erhöht werden, indem die gesamte Gleisfreimeldeanlage in doppelter Ausführung installiert wird.In their environment of use, however, axle counting sensors are exposed to numerous disturbing influences. To rule out miscounts or at least reduce their probability, Various algorithms and arrangements are known which allow a plausibility of the counts. For example, the availability of faults and failures can be increased by installing the entire train detection system in duplicate.
Bei allen bekannten Achszählsensoren muss ein enormer Aufwand bei der Signalaufbereitung, -verarbeitung und -auswertung betrieben werden. Die dazu notwendigen Algorithmen müssen baulich bedingte Konstruktionen der Schienenfahrzeuge, zum Beispiel heruntergeklappte Einstiegstreppen aus Metall, berücksichtigen, um Fehlzählungen und Fehlinterpretationen möglichst zu vermeiden, wobei die Fehlerquote dennoch hoch sein kann.With all known axle counting sensors, a tremendous effort has to be made in signal processing, processing and evaluation. The algorithms necessary for this have to take into account construction-related constructions of rail vehicles, for example folded-down access staircases made of metal, in order to avoid miscalculations and misinterpretations as far as possible, although the error rate can nevertheless be high.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Raderkennungseinrichtung gattungsgemäßer Art anzugeben, welche eine zuverlässigere Erfassung der Gleisüberfahrung und damit eine Erhöhung der Verfügbarkeit ermöglichen.The invention has for its object to provide a method and a wheel detection device of the generic type, which allow a more reliable detection of the track override and thus an increase in availability.
Verfahrensgemäß wird die Aufgabe durch die Merkmale des Anspruches 1 gelöst.According to the method, the object is achieved by the features of
Durch dieses Plausibilisierungsverfahren werden Fehlzählungen unterdrückt. Die Funktionalität der Raderkennung ist weiterhin gegeben, wenn entweder der Achszählsensor oder der zweite Sensor eine Radüberfahrung feststellt, so dass sich die Verfügbarkeit des Gesamtsystems erhöht.This plausibility check method suppresses miscounts. The functionality of the wheel detection is still given if either the axle counting or the second sensor detects a wheel overdrive, so that increases the availability of the entire system.
Die Aufgabe wird gemäß Anspruch 2 auch durch eine Raderkennungseinrichtung gelöst, bei der ein zweiter Sensor zur Erfassung der Überfahrung des Gleises vorgesehen ist, wobei der zweite Sensor und der Achszählsensor diversitäre Hardware und/oder Software aufweisen und wobei die Signalausgänge des Achszählsensors und des zweiten Sensors mit einem Vergleicher und einem Timer zur Vorgabe eines Zeitfensters zur Feststellung, ob innerhalb des Zeitfensters in derselben Fahrtrichtung eine Überfahrung des Gleises durch ein weiteres Rad erfolgt ist, verbunden sind.The object is achieved according to
Auf diese Weise ist eine Plausibilisierung oder Widerspruchsauflösung bei der Raderkennung und damit eine Erhöhung der Verfügbarkeit der Raderkennungseinrichtung möglich.In this way, a plausibility or contradiction resolution in the wheel detection and thus an increase in the availability of the wheel detection device is possible.
Im Normalfall wird die Überfahrung des Gleises im Wesentlichen gleichzeitig durch den Achszählsensor und den zweiten Sensor erfasst.Normally, track overrun is detected substantially simultaneously by the axle counting sensor and the second sensor.
Falls jedoch nur einer der beiden Sensoren eine Radüberfahrung erfasst, wird diese Raderfassung nur dann als tatsächliche Erkennung eines Rades gewertet beziehungsweise gezählt, wenn innerhalb eines bestimmten Zeitfensters ein weiteres Rad, vorzugsweise das nächste Rad, von beiden Sensorn detektiert wird. Dazu wird das Erfassungsergebnis, bei dem nur einer der beiden Sensoren eine positive Erfassung registriert hat, zunächst unterdrückt, wobei ein Marker mit Zeitstempel aktiviert wird, wodurch ein Fehler registriert wird. Mit dem Zeitstempel wird der Timer zur Vorgabe des definierten Zeitfensters aktiviert. Wird innerhalb dieses Zeitfensters durch beide Sensoren ein zweites Rad erfasst, wird die Unterdrückung des ersten Erfassungsergebnisses zurückgesetzt und die Anzahl der erkannten Achsen beziehungsweise Räder wird auf zwei gesetzt.If, however, only one of the two sensors detects a wheel override, this wheel detection is only scored or counted as the actual detection of a wheel if, within a specific time window, another wheel, preferably the next wheel, is detected by both sensors. For this purpose, the detection result, in which only one of the two sensors has registered a positive detection, initially suppressed, with a marker is activated with a time stamp, whereby an error is registered. The timestamp activates the timer for specifying the defined time window. If a second wheel is detected by both sensors within this time window, the suppression of the first detection result is reset and the number of detected axes or wheels is set to two.
Durch die gemeinsame algorithmische Auswertung der Ausgangssignale des herkömmlichen Achszählsensors und des zweiten Sensors kann jedes einzelne Rad sicher identifiziert werden. Fehlzählungen und Fehlinterpretationen werden weitgehend ausgeschlossen. Durch den zweiten Sensor kann letztlich auch die übliche Verschaltung mehrerer Achszählsensoren zur sicherheitstechnischen Detektion eines Überfahrpunktes oder Zählpunktes vereinfacht werden.By the common algorithmic evaluation of the output signals of the conventional axle counting sensor and the second sensor, each individual wheel can be identified with certainty. Missing counts and misinterpretations are largely excluded. Ultimately, the customary interconnection of several axle counting sensors for the safety-related detection of a crossover point or point of delivery can also be simplified by the second sensor.
Um systematische Fehler, beispielsweise bei der Projektierung der Achszählpunktrechner, zu vermeiden, unterscheidet sich der zweite Sensor hinsichtlich Hardware und/oder Software von dem vorhandenen Achszählsensor. Der zweite Sensor beruht auf einem unabhängigen physikalischen Prinzip und wird vorzugsweise nur dann aktiviert, wenn ein Radreifen den Sensor unmittelbar beeinflusst.In order to avoid systematic errors, for example when configuring the axle counting point computer, the second sensor differs in terms of hardware and / or software from the existing axle counting sensor. The second sensor is based on an independent physical principle and is preferably activated only when a wheel tire directly affects the sensor.
Dazu ist der zweite Sensor gemäß Anspruch 3 vorzugsweise zur Erfassung einer Gleisdurchbiegung ausgebildet. Derartige Sensoren sind zum Beispiel für Energy-Harvesting-Anwendungen bekannt. Das Gleisdurchbiegungsprinzip des zweiten Sensors kann auch als Wiegesystem ausgebildet sein, indem die Belastung des Radreifens und damit die Gleisbefahrung erfasst wird. Durch Aufnahme einer Gewichts-Messkurve wird das Hinein- und Herausrollen des Radreifens festgestellt, wodurch jeder einzelne Radreifen sicher identifiziert werden kann. Darüber hinaus ist der als Wiegesystem ausgebildete oder auf Gleisdurchbiegung basierende zweite Sensor universell, das heißt für jede Art von Radreifen, insbesondere auch für gummibereifte Eisenräder, einsetzbar.For this purpose, the second sensor according to
Ein anderes Funktionsprinzip des zweiten Sensors beruht gemäß Anspruch 4 auf die Verwendung einer Kamera. Diese kann beispielsweise durch einen einfachen Schienenschalter aktiviert werden.Another operating principle of the second sensor is based on the use of a camera according to claim 4. This can be activated for example by a simple rail switch.
Gemäß Anspruch 5 ist vorgesehen, dass der zweite Sensor und der Achszählsensor in Gleisrichtung versetzt zueinander angeordnet sind. Auf diese Weise kann zusätzlich die Fahrtrichtung des Schienenfahrzeuges festgestellt werden. Beim Überfahren des Gleises durch ein Rad erzeugen die beiden Sensoren zeitlich versetzte Radimpulse, die zur Fahrtrichtungserkennung dienen.According to claim 5 it is provided that the second sensor and the axle counting are arranged offset in the track direction to each other. In this way, additionally the direction of travel of the rail vehicle can be determined. When passing over the track by a wheel, the two sensors generate time-shifted wheel pulses, which are used for direction detection.
Vorzugsweise ist der zweite Sensor gemäß Anspruch 6 zusätzlich oder alternativ zur Umschaltung des Achszählsensors zwischen Schlafmodus und Aktivmodus ausgebildet. Diese Energy-Harvesting-Funktionalität ermöglicht die Bestromung des Achszählsensors ausschließlich während der Zeiträume, in denen tatsächlich eine Radüberfahrung des Gleises erwartet wird.Preferably, the second sensor according to claim 6 additionally or alternatively to the switching of the axle counting between Sleep mode and active mode formed. This energy harvesting functionality allows the axle counting sensor to be energized only during the periods when the track is expected to over-ride the wheel.
Nachfolgend wird die Erfindung anhand einer Flow-Chart-Darstellung näher erläutert.The invention will be explained in more detail below with reference to a flowchart representation.
Veranschaulicht ist ein erfindungsgemäßer Verfahrensablauf zur Raderkennung eines ein Gleis überfahrenden Schienenfahrzeuges mittels zweier diversitärer Sensoren, die dem gleichen Messort zugeordnet sind.Illustrated is a method sequence according to the invention for wheel recognition of a rail vehicle traveling over a track by means of two diversified sensors which are assigned to the same measuring location.
Nach dem Start (0) wird zunächst festgestellt, ob ein Marker gesetzt ist und ein Timer zur Vorgabe eines bestimmten Zeitfensters noch läuft (0a). Wenn das der Fall ist, werden diese gelöscht (0b). Danach wird festgestellt, ob beide Sensoren eine Achse erkennen (1). Dazu werden die beiden Erfassungsergebnisse der beiden Sensoren miteinander verglichen (2).After the start (0), it is first determined whether a marker is set and a timer for specifying a specific time window is still running (0a). If so, they will be deleted (0b). It is then determined whether both sensors detect an axis (1). For this purpose, the two detection results of the two sensors are compared (2).
Im Normalfall registrieren beide Sensoren annähernd gleichzeitig (3) eine Radüberfahrt (Ja + Ja), wodurch die Überfahrung eines Rades als sicher gilt (7a).Normally, both sensors register (3) a wheel crossing (Yes + Yes) almost simultaneously (3), whereby the wheel overrun is considered safe (7a).
Falls nur einer der beiden Sensoren ein Rad oder eine Achse erfasst hat (Ja + Nein oder Nein + Ja) und der Marker dieses gespeichert hat (4a), wodurch der Timer gestartet wird (4b) beginnt die Schleife erneut (4c) mit Start (0).If only one of the two sensors has detected a wheel or axle (Yes + No or No + Yes) and the marker has stored it (4a), which starts the timer (4b), the loop starts again (4c) with Start (4c). 0).
Nur wenn bei diesem zweiten Durchlauf von beiden Sensoren während des von dem Timer vorgegebenen Zeitfensters (5a) eine Achse erfasst wurde (Ja + Ja), wird das erste Erfassungsergebnis (Ja + Nein oder Nein + Ja) nach dem Löschen des Markerspeichers (5b) als korrekte Zählung gewertet, so dass nach dieser zweiten Schleife zwei Räder als erkannt gelten (7b). Danach beginnt die Schleife erneut (8).Only when an axis has been detected by both sensors during the time window (5a) given by the timer (Yes + Yes), the first detection result (Yes + No or No + Yes) after clearing the marker memory (5b) evaluated as correct count, so that after this second loop, two wheels are considered recognized (7b). Then the loop starts again (8).
Falls jedoch bei gesetztem Marker, das heißt innerhalb des Zeitfensters (4d), beim zweiten Durchlauf keine Achse erfasst wurde (Nein + Nein), wird der Timer auf 0 gesetzt (4e), auch wenn das Zeitfenster eventuell noch nicht abgelaufen ist. Folglich gilt keine Achse als erkannt (6a) und es wird auch kein Radimpuls registriert (6b).However, if no axis was detected on the second pass (No + No) with the marker set, ie within the time window (4d), the timer is set to 0 (4e), even if the time window may not have expired yet. Consequently, no axis is recognized (6a) and no wheel pulse is registered (6b).
Dieses Verfahren ermöglicht eine verbesserte Verfügbarkeit des Gesamtsystems zur Achszählung, insbesondere auch dann, wenn nur einer der beiden Sensoren eine Achse erfasst hat (Ja + Nein oder Nein + Ja). Derartige Zählfehler werden automatisch korrigiert.This method enables improved availability of the overall axle counting system, especially if only one of the two sensors has detected an axle (Yes + No or No + Yes). Such counting errors are corrected automatically.
