Abstract
Description
Die Erfindung bezieht sich auf eine Einrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a device according to the Preamble of claim 1.
Im schienengebundenen Bahnbetrieb bestimmen die Züge ihren jeweiligen Fahrort innerhalb eines Gleisabschnittes regelmäßig durch Zählen der seit Eindringen in den Abschnitt ausgeführten Radumdrehungen eines vorzugsweise nicht angetriebenen Fahrzeugrades. Hierzu weisen das oder die für die Fahrortbestimmung verwendeten Räder eine oder mehrere über den Umfang verteilt angeordnete Anomalien auf, die von einem Radimpulsgeber beim Vorbeibewegen an einem Aufnahmekopf detektiert werden. Der Radimpulsgeber führt die detektierten Radimpulse einem Wegzähler zu, der sie entsprechend dem Raddurchmesser und der Teilung des steuernden Fahrzeugrades in eine entsprechende Wegangabe umsetzt. Die Angaben über den jeweiligen Fahrort eines Zuges benötigt dieser zum rechtzeitigen Abbremsen auf vorgegebene Zielgeschwindigkeiten an vorgegebenen Zielpunkten.The trains determine theirs in rail-bound operation respective location within a track section regularly by counting the number of runs performed since entering the section Wheel revolutions of a preferably not driven one Vehicle wheel. For this purpose, the one or more point for determining the driving location used wheels one or more over the circumference distributed anomalies on by a wheel encoder detected when moving past a recording head will. The wheel pulse generator guides the detected wheel pulses to a distance counter, which corresponds to the wheel diameter and the division of the steering vehicle wheel into a corresponding one Implements directions. The information about the respective The location of a train needs it to slow down in time to predetermined target speeds at predetermined Target points.
Obgleich die Radimpulse vorzugsweise an einem nicht angetriebenen Fahrzeugrad abgegriffen werden, kommt es durch Schlupf und Gleiten regelmäßig zu mehr oder weniger großen Abweichungen zwischen tatsächlichem Fahrort eines Fahrzeugs und dem vom Fahrzeug selbst ermittelten Fahrort. Aus diesem Grunde wird das fahrzeugseitige Wegmeßergebnis mindestens dann, wenn es auf eine exakte Ortungsangabe ankommt, während des Vorrückens des Fahrzeugs an vorgegebenen Fahrorten mit einer Angabe über den tatsächlichen Fahrort synchronisiert. Dies geschieht z. B. bei mit Linienzugbeeinflussung ausgerüsteten Strecken und Fahrzeugen jeweils beim Passieren von Linienleiterkreuzungen, welche die Strecken in vorgegebene Streckenabschnitte unterteilen (ETR 20 (1971)7/8, Seiten 326-336). Although the wheel pulses are preferably on a non-driven one Vehicle wheel can be tapped, it occurs due to slippage and sliding regularly to more or less large deviations between the actual driving location of a vehicle and the location determined by the vehicle itself. For this reason the vehicle-side measuring result is at least if an exact location is important during the advance of the vehicle at specified locations with an indication synchronized over the actual driving location. this happens e.g. B. in lines equipped with line control and vehicles each when crossing line conductor crossings, which the routes in predetermined route sections subdivide (ETR 20 (1971) 7/8, pages 326-336).
Bei nicht mit derartigen Einrichtungen ausgerüsteten Strecken und Fahrzeugen gelingt die Anpassung eines fahrzeugseitigen Ortungsergebnisses an eine absolute Ortsangabe z. B. dadurch, daß an vorbestimmten Punkten der Strecke vorzugsweise passive Gleiskoppelspulen, punktförmige Zugbeeinflussungseinrichtungen oder Antwortgeräte, wie sie für die Güterwagennummernmeldung entwickelt wurden, angebracht und vom vorüberlaufenden Fahrzeug erkannt werden (DE-OS 22 23 413). Es ist auch bereits bekannt, zur Fahrortbestimmung von Schienenfahrzeugen zusätzlich zu den Linienleiterkreuzungen noch Streckenmarken anzuordnen, die eine absolute Ortsangabe an die vorüberlaufenden Fahrzeuge übermitteln (DE-AS 20 42 090).For routes not equipped with such facilities and vehicles succeed the adaptation of a vehicle side Location result to an absolute location z. B. thereby that preferably at passive points on the route Track coupling coils, punctiform train control devices or answering devices, such as those used for reporting freight wagons were developed, attached and by the passing Vehicle can be recognized (DE-OS 22 23 413). It is also already known, for determining the location of rail vehicles in addition to the line crossings, route marks to arrange an absolute location to the passing Transmit vehicles (DE-AS 20 42 090).
Alle diese Einrichtungen dienen dazu, unvermeidbare Fehlmessungen der Wegmeßeinrichtungen infolge von Schlupf und Gleiten zu korrigieren. Dort wo es auf eine hochgenaue Ortung zum Zwecke einer punktgenauen Zielbremsung im Dezimeter- oder Zentimeterbereich ankommt, genügen diese bekannten Maßnahmen für die Korrektur von Ortungsergebnissen noch nicht. Allein dadurch, daß vom Erkennen der für die Ortungskorrektur verwendeten Ortsmarken bis zum Bereitstellen eines entsprechenden Ortungsergebnisses durch das Fahrzeug eine gewisse Zeit vergeht, ist das dann bereitgestellte Ortungsergebnis nicht mehr aktuell, sondern bereits veraltet. Hinzu kommt, daß die Ortsmarken nicht streng punktförmig erkannt werden, sondern daß es einen Ansprechbereich gibt, der von Fall zu Fall verschieden sein und in der Größenordnung von ± 20 cm variieren kann. Hierdurch wird das Ortungsergebnis wieder ungenau.All of these facilities serve to prevent unavoidable incorrect measurements of the measuring devices due to slippage and sliding to correct. Where there is a high-precision location for Purposes of precise braking in the decimeter or Centimeter range arrives, these known measures are sufficient not yet for the correction of location results. Alone in that by recognizing those used for the location correction Placemarks until a corresponding one is provided Locating result by the vehicle for a certain time the location result then provided is not more current, but already out of date. In addition, the Placemarks are not recognized as strictly punctiform, but that there is a response area that is case by case be different and vary in the order of ± 20 cm can. As a result, the location result is again inaccurate.
Aufgabe der Erfindung ist es, eine Einrichtung nach dem Oberbegriff des Anspruches 1 anzugeben, deren Ortungsergebnisse weitgehend unabhängig sind von den fahrzeuginternen Verzugszeiten zwischen dem Erkennen einer Ortsmarke und dem Bereitstellen einer Ortungsangabe und dem zufällig vorhandenen Übertragungsverhältnissen zwischen den Fahrzeugen und den Ortsmarken. The object of the invention is to provide a device according to Specify the preamble of claim 1, their location results are largely independent of the vehicle's interior Delays between the recognition of a placemark and the Providing a location information and the randomly existing Transmission relationships between the vehicles and the Placemarks.
Die Erfindung löst diese Aufgabe durch die kennzeichnenden Merkmale des Anspruches 1. Durch die hochgenaue Ortung der Ortsmarken und die Korrektur der Ortungsangaben nach Maßgabe des während der Verzugszeit zurückgelegten Fahrweges kann der Fahrzeugsteuerung für die Zielbremsung ein außerordentlich exakter Fahrort vorgegeben werden , der unabhängig ist von der für die Fahrorterkennung erforderlichen Verarbeitungszeit eines Fahrzeuggerätes.The invention solves this problem by the characterizing Features of claim 1. By the highly accurate location of the Placemarks and the correction of location information as required of the route covered during the delay time can Vehicle control for target braking an extraordinary exact location, which is independent of the processing time required for driver identification a vehicle device.
Vorteilhafte Aus- und Weiterbildungen der erfindungsgemäßen Einrichtung sind in den Unteransprüchen angegeben.Advantageous training and further developments of the invention Facility are specified in the subclaims.
Das Ortungsergebnis läßt sich noch weiter verbessern, wenn
gemäß Anspruch 2 neben der Vorrückgeschwindigkeit auch eine
etwaige Beschleunigung des Fahrzeugs für die Korrektur des
Ortungsergebnisses herangezogen wird.
Neben der Berücksichtigung einer für die Bildung von Ortungsergebnissen
erfahrungsgemäß benötigten Zeitspanne soll nach
der Lehre des Anspruches 3 das Fahrzeug die für die Übertragung
und Verarbeitung von Ortungskennzeichen erforderliche
tatsächliche Zeitspanne selbst feststellen und damit eine
optimale Ortungskorrektur ermöglichen.
Die Ortsmarken sollen gemäß Anspruch 4 als vom Fahrzeug
detektierbare passive Gleiskoppelspulen, punktförmige Zugbeeinflussungseinrichtungen
oder passive Antwortgeräte ausgebildet
sein. Dies hat den Vorteil, daß für die Ortung auf
einer Strecke keine zusätzliche Stromversorgung erforderlich
ist.
Erstreckt sich ein Bremsvorgang auf eine längere Wegstrecke
oder sollen Fahrzeuge auf unterschiedliche Zielpunkte gebremst
werden, so kann es nach der Lehre des Anspruches 5 von
Vorteil sein, entlang der Strecke mehrere Ortsmarken im
Abstand anzuordnen.
Anstelle passiver Elemente können für die Übermittlung von
Ortsmarken in an sich bekannter Weise nach der Lehre des
Anspruches 6 auch Linienleiter vorgesehen sein, deren Leitungen
in vorgegebenen Abständen gekreuzt sind.The locating result can be further improved if, in addition to the advancing speed, any acceleration of the vehicle is used for the correction of the locating result.
In addition to taking into account a period of time that is empirically required for the formation of location results, according to the teaching of claim 3, the vehicle itself should determine the actual time period required for the transmission and processing of location indicators and thus enable an optimal location correction.
According to claim 4, the placemarks should be designed as passive track coupling coils detectable by the vehicle, punctiform train control devices or passive answering devices. This has the advantage that no additional power supply is required for location on a route.
If a braking process extends over a longer distance or if vehicles are to be braked to different destination points, then it can be advantageous according to the teaching of claim 5 to arrange a plurality of placemarks along the route at a distance.
Instead of passive elements, line conductors whose lines are crossed at predetermined intervals can also be provided for the transmission of placemarks in a manner known per se according to the teaching of claim 6.
Die Erfindung ist nachstehend anhand eines in der Zeichnung schematisch und ausschnittsweise dargestellten Ausführungsbeispieles näher erläutert.The invention is based on one in the drawing schematically and partially illustrated embodiment explained in more detail.
Die Zeichnung zeigt die beiden Funktionsgruppen ATP (automatic train protection) und ATO (automatic train operation) eines Fahrzeuggerätes; die ATP dient der Sicherung des Fahrbetriebs, die ATO der automatischen Steuerung des Fahrzeugs. Im unteren Teil der Darstellung sind ein vorzugsweise nicht angetriebenes Fahrzeugrad R eines zu steuernden Fahrzeugs und ein die Bewegung des Fahrzeugrades detektierender Radimpulsgeber RG dargestellt. Der Radimpulsgeber liefert die von ihm detektierten Radsignale an einen Wegzähler W, der die Radsignale aufsummiert und der ATO entsprechende Wegstreckenangaben s zur Eigenortung des Fahrzeugs auf der Strecke zuführt. Aus der Änderung dieser Streckenangaben ermittelt sich die ATO die augenblickliche Fahrgeschwindigkeit V, die sie zusammen mit den Wegstreckenangaben für die Fahrzeugsteuerung benötigt. Zur Synchronisation der von der Wegmeßeinrichtung W aus den Radimpulsen bestimmten Fahrortangaben mit dem tatsächlichen Fahrort sind an vorgegebenen Streckenpunkten, die dem Fahrzeug bekannt sind oder bekannt gegeben werden, Ortsmarken z. B. in Form von Gleiskoppelspulen GKS oder andere punktförmig wirkende Übertragungseinrichtungen zur Kennzeichnung des jeweiligen Fahrortes angeordnet. Das Fahrzeug ist mit einer fahrzeugseitigen Koppelspule FKS ausgerüstet, die beim Vorüberlaufen an der ortsfesten Gleiskoppelspule GKS mit dieser koppelt und dabei vorübergehend seine Stromaufnahme I markant verändert. Der dabei z. B. auftretende Strompegeleinbruch wird auf dem Fahrzeug in ein entsprechendes Rechtecksignal einer Spannung U umgesetzt, wobei von den Flanken dieses Signal Interrupts INT gebildet werden zur Bestimmung der Beeinflussungszeit tB des Fahrzeuggerätes durch die Gleiskoppelspule. Nach dem zweiten Interrupt kann die ATO im Nachhinein durch Mittelwertbildung den Zeitpunkt bestimmen, an dem sich die Gleiskoppelspule und die fahrzeugseitige Koppelspule genau gegenüber standen. Diese Zeitbestimmung ist unabhängig von den jeweiligen Beeinflussungsverhältnissen, welche die zeitliche Dauer der Beeinflussung bestimmen und im wesentlichen vom räumlichen Abstand der fahrzeugseitigen und der streckenseitigen Beeinflussungseinrichtungen abhängig sind. Ein entsprechendes Synchronisiersignal SYN veranlaßt in der ATO eine Zeitmessung für die Bestimmung der Verzugszeit tx zwischen dem Passieren der Ortsmarke und der Bereitstellung der Ortungsinformation ORT durch die ATO. Diese Verzugszeit ist im wesentlichen durch die Übertragungszeit der für die Fahrzeugsteuerung benötigten Daten an die ATO sowie dem Einphasen dieser Daten und das Verarbeiten dieser Daten in der ATO bestimmt. Die ATO bestimmt nun aus der aktuellen Geschwindigkeit Vx des Fahrzeugs und der gemessenen Verzugszeit tx eine Wegstrecke sx, die das Fahrzeug vom hochgenauen Erkennen der Ortsmarke bis zum Bereitstellen des Ortungsergebnisses ORT vorgerückt ist. Um diese Wegstrecke sx ist die von der Wegmeßeinrichtung W zur Verfügung gestellte Ortsangabe s zu korrigieren, um zu einem absoluten Ortungsergebnis ORT* zu gelangen, das eine hochgenaue Zielbremsung im Bereich von einigen Zentimetern zuläßt.The drawing shows the two functional groups ATP (automatic train protection) and ATO (automatic train operation) a vehicle device; the ATP serves to secure the Driving operation, the ATO of automatic control of the vehicle. In the lower part of the illustration, one is preferred non-driven vehicle wheel R of a vehicle to be controlled and a movement detecting the vehicle wheel Wheel pulse generator RG shown. The wheel pulse generator delivers the by him detected wheel signals to a path counter W, the Summed up wheel signals and the ATO corresponding route information s for self-locating the vehicle on the route feeds. Determined from the change in this route information the ATO the current driving speed V, the it together with the route information for the vehicle control needed. For the synchronization of the distance measuring device W determined from the wheel pulses driving location information with the actual driving location are at predetermined route points, that are known or made known to the vehicle be, placemarks z. B. in the form of track coupling coils GKS or other point-like transmission devices arranged to identify the respective driving location. The Vehicle is equipped with a coupling coil FKS on the vehicle equipped, when passing the fixed track coupling coil GKS couples with it and temporarily its current consumption I changed significantly. The z. B. The current level drop occurs on the vehicle corresponding square wave signal of a voltage U implemented, whereby this signal forms interrupts INT are used to determine the influencing time tB of the vehicle device through the track coupling coil. After the second interrupt can the ATO afterwards by averaging Determine the time at which the track coupling coil and the vehicle-side coupling coil were exactly opposite. This Time determination is independent of the respective influencing conditions, which is the duration of the influence determine and essentially from the spatial distance of the vehicle-side and track-side influencing devices are dependent. A corresponding synchronization signal SYN initiates a time measurement for the determination in the ATO the delay time tx between passing the placemark and the provision of the location information by ORT the ATO. This delay is essentially due to the Transmission time of those required for vehicle control Data to the ATO as well as the phasing of this data and that Processing of this data is determined in the ATO. The ATO determines now from the current speed Vx of the vehicle and the measured delay time tx is a distance sx that the Vehicle from the highly accurate recognition of the placemark to Providing the location result is advanced. Around this distance sx is that from the distance measuring device W to Corrected location s to correct to a absolute location result ORT * to arrive, which is a highly accurate Allows target braking in the range of a few centimeters.
In die Bestimmung des Wegstrecken-Korrekturwertes sx fließen entweder die jeweils aktuellen Geschwindigkeitswerte des Fahrzeugs ein oder aber es wird die Geschwindigkeit beim Passieren der Ortsmarke verwendet, wobei die jeweiligen Werte dieser Geschwindigkeit nach Maßgabe der aktuellen Beschleunigung des Fahrzeugs gegebenenfalls zu modifizieren sind.Flow into the determination of the distance correction value sx either the current speed values of the Vehicle or it will speed at Passing the placemark used, the respective values this speed in accordance with the current acceleration of the vehicle may need to be modified.
Anstelle einer einzigen können auch mehrere im Abstand angeordnete Ortsmarken zur mehrmaligen Synchronisierung der fahrzeugseitig ermittelten relativen Ortungsergebnisse mit den absoluten Positionsangaben der Ortsmarken vorgesehen sein. Als Ortsmarken können neben Gleiskoppelspulen auch punktförmige Zugbeeinflussungseinrichtungen oder Antwortgeräte verwendet sein, wie sie für die Zugnummernmeldung und die Güterwagennummernmeldung entwickelt wurden.Instead of a single one, several can be arranged at a distance Placemarks for multiple synchronization of the relative location results determined on the vehicle side the absolute position information of the placemarks be. In addition to track coupling coils, placemarks can also be used punctiform train control devices or response devices be used as it is for train number reporting and the freight car number message was developed.
Die erfindungsgemäße Einrichtung eignet sich insbesondere für eine hochgenaue Zielbremsung von Fahrzeugen im Bahnhofsbereich und zwar insbesondere dort, wo die Fahrgastströme z. B. durch Absperrgitter oder Türen auf bestimmte Stellen des Bahnhofs kanalisiert werden und die Notwendigkeit besteht, daß die Fahrzeuge mit ihren Türen zentimetergenau in diesen Ein- und Aussteigebereichen zu positionieren sind.The device according to the invention is particularly suitable for high-precision target braking of vehicles in the station area in particular where the passenger flows z. B. through barriers or doors at certain points of the Station canalized and there is a need that the vehicles with their doors in this centimeter Entry and exit areas are to be positioned.
Die Erfindung ist mit Vorteil auch dort anwendbar, wo der jeweilige Fahrort eines Fahrzeugs in einem Streckenabschnitt nicht über einen Wegzähler für Radsignale sondern über beliebige andere fehlerbehaftete Wegmeßeinrichtung bestimmt wird oder wo es ausschießlich auf eine hochgenaue Ortung beim Vorbeifahren an einer Ortsmarke ankommt.The invention is also advantageously applicable where the respective location of a vehicle in a section of the route not via a path counter for wheel signals, but via any other faulty displacement measuring device is determined or where it is exclusively for a highly precise location at Passing a placemark arrives.
