Abstract

The appts. is used for maintaining proper distances between rail-bound, suspension vehicles with long stator,linear motor drive. It uses probes for detecting the presence of a vehicle. In the stator section behind the vehicle the drive current is switched off via the probes, loop transmitters for line conductors loops behind the vehicle are cut-off. A forced braking of a following vehicle is triggered by the absence of a "free signal" from the loop transmitter, and/or of the absence of drive current. Preferably fair-safe double probes are fitted to the boundaries of the stator sections. The probes may be in form of pressure contacts in the vehicle supports. The process can be also used for normal trains and rail-bound vehicles.

Description

Verfahren zur Abstandshaltung zwischen spurgebundenenMethod of spacing between track-bound

Fahrzeugen Die Erfindung betrifft ein Verfahren zur Abstandshaltung zwischen spurgebundenen Fahrzeugen nach dem Oberbegriff des Patentanspruches 1.Vehicles The invention relates to a method for keeping a distance between track-bound vehicles according to the preamble of claim 1.

In der konventionellen Eisenbahntechnik werden für die Sicherung des Zugbetriebes und zum Uberwachen des Betriebsablaufes die Gleise in eine Folge von gleichen Streckenabschnitten unterteilt. Diese werden daraufhin überwacht, ob sie durch Fahrzeuge besetzt oder frei sind.In conventional railway technology, the Train operation and to monitor the operation of the tracks in a sequence of divided into the same route sections. These are monitored to see if they are occupied or free by vehicles.

Zum Überwachen der einzelnen Gleisabschnitte verwendet man vielfach Gleisstromkreise. Ein solcher Gleisstromkreis besteht aus einer Wechselstromquelle, der als Sender bezeichnet werden kann und der über die Fahrschienen eines Eisenbahngleises einen Empfänger speist. Die Trennung von den benachbarten Gleisabschnitten wird durch Isolierstöße bewirkt. Stellt ein Fahrzeug durch seine Achsen eine niederohmige Verbindung zwischen den Fahrschienen her, so gelangt kein Strom mehr in den Empfänger, der daraufhin den Gleisabschnitt besetzt meldet (Signal und Draht 71 (1979) 5, Aufsatz Hans Dewald: "Tonfrequenzgleichstromkreise). Bei Schwebe-Fahrzeugen mit Langstatorlinearmotorantrieb kann dieses Verfahren aedoch nicht angewendet werden.One uses a lot to monitor the individual track sections Track circuits. Such a track circuit consists of an alternating current source, which can be referred to as a transmitter and which over the rails of a railroad track feeds a receiver. The separation from the neighboring track sections is caused by insulating joints. Represents a vehicle by his axles If there is a low-resistance connection between the rails, no current can get through more into the receiver, which then reports the track section occupied (signal and Draht 71 (1979) 5, article by Hans Dewald: "Audio frequency DC circuits). In suspension vehicles However, this method cannot be used with a long-stator linear motor drive.

Die Aufgabe besteht daher darin, ein Verfahren zur Abstandshaltung zu schaffen, das auch bei Schwebe-Fahrzeugen angewendet werden kann. Die Aufgabe wird nach der Erfindung durch die in den Patentansprüchen angegebenen Maßnahmen gelöst.The task is therefore to find a method for keeping the distance to create that can also be used in levitation vehicles. The task is according to the invention by the measures specified in the claims solved.

Die Erfindung wird im folgenden anhand einer Zeichnung an einem Ausführungsbeispiel näher erläutert.The invention is illustrated below with reference to a drawing of an exemplary embodiment explained in more detail.

Das Langstatorantriebssystem ist in einzelne Langstatorabschnitte von ca. 150 m Länge aufgeteilt.The long stator drive system is in individual long stator sections 150 m long.

Für jeden Abschnitt wird bei Einfahrt eines Zuges in diesen Abschnitt der Antriebsstrom eingeschaltet und bei Ausfahrt wieder ausgeschaltet.For each section, when a train enters this section the drive current is switched on and switched off again when the vehicle is exiting.

Die Erfassung der Züge pro Abschnitt erfolgt durch Sonden a, b an den Grenzen jedes Langstatorabschnittes, die z. B.The trains per section are recorded by probes a, b an the limits of each long stator section, which z. B.

durch einen dauernd eingeschalteten Sender auf dem Zug bei Vorbeifahrt angestrahlt werden. Es können auch passive Sonden verwendet werden, die durch die Zugmasse bedämpft werden oder Druckkontakte in den Stützen des aufgeständerten Fahrweges.by a permanently switched on transmitter on the train when passing be illuminated. Passive probes can also be used which are driven by the Tensile mass are damped or pressure contacts in the supports of the elevated track.

Bestandteil der Folgeverriegelung ist die Überwachung der Sondenpaare. Die Empfangssonden selbst sind nicht failsafe aufgebaut. Deshalb werden pro Abschnittsgrenze zwei Sonden eingesetzt, die durch die nachfolgende Failsafeüberwachung bei jeder Fahrt auf einwandfreie Funktion überwacht werden.Monitoring of the probe pairs is part of the follow-up locking. The receiving probes themselves are not failsafe built up. That's why two probes are used per section boundary, which are monitored by the subsequent fail-safe monitoring are monitored for proper function during every journey.

Zur Freischaltung des zurückliegenden Abschnittes müssen beide Sonden eines Paares den Signalwechsel "frei - belegt - frei" ordnungsgemäß abwickeln.To activate the previous section, both probes must of a pair properly handle the signal change "free - occupied - free".

Die Sperrung des Antriebsstromes für die einzelnen Langstatorabschnitte erfolgt durch eine gesonderte, in jedem hier nicht dargestellten Unterwerk angeordnete Verriegelungsebene durch Schütze. Diese werden von der Folgeverriegelung angesteuert, die aus den Sonden und der über wachung besteht. Über zwangsgeführte Rückmeldekontakte wird die tat-sächliche Lage dieser Schütze in die Folgeverriegelung der Zugsicherung einbezogen.The blocking of the drive current for the individual long stator sections takes place through a separate, arranged in each substation, not shown here Locking level by contactors. These are controlled by the subsequent interlocking, which consists of the probes and the monitoring. Via positively driven feedback contacts the actual position of this contactor is in the subsequent locking of the train protection included.

Der fehlende Antriebsstrom wird auf dem Fahrzeug signaltechnisch sicher zur Ansteuerung der Schienenbremse ausgewertet.The missing drive current is signal-technically safe on the vehicle evaluated for controlling the rail brake.

Ergänzend oder alternativ wird ein zusätzliches System installiert. Jeder Langstatorabschnitt erhält eine Leiterschleife und einen zugehörigen Sender. Mit dieser Einrichtung wird ein kontinuierliches Freigabesignal ("nicht bremsen") an die Züge ausgestrahlt.In addition or as an alternative, an additional system is installed. Each long stator section receives a conductor loop and an associated transmitter. With this device a continuous release signal ("do not brake") broadcast to the trains.

Wiederum von der Folgeverriegelung abgeleitet wird der jeweils hinter einem belegten Abschnitt liegende Sender abgeschaltet, so daß ein hier einfahrender Zug kein Freigabesignal erhält. Eine Auswertung auf dem Zug steuert daraufhin die Schienenbremse an. Diese zusätzliche Sicherung ist besonders dann von Wichtigkeit, wenn wie bei U-Bahnen der Antrieb nur kurzzeitig eingeschaltet wird und das Fahrzeug sich dann antriebslos bis zur nächsten Station weiter bewegen soll.In turn, the one behind is derived from the subsequent locking An occupied section lying transmitter switched off, so that one entering here Train does not receive a release signal. An evaluation on the train then controls the Rail brake on. This additional backup is especially then This is important if the drive is only switched on for a short time, as is the case with underground trains and the vehicle will then continue to move without drive to the next station target.

Der Ausfall des Strombelages wird auf dem Fahrzeug durch eine Bailsafe-Logik erkannt. Diese Logik läßt die Schienenbremse einfallen und verhindert dadurch, daß das Fahrzeug antriebslos über die Tasse schwebt.The failure of the power supply is indicated on the vehicle by a bailsafe logic recognized. This logic lets the rail brake apply and thereby prevents that the vehicle hovers over the cup with no drive.

Durch das beschriebene Verfahren nach der Erfindung wird eine sichere Abstandshaltung auch bei Magnetschwebe-Fahrzeugen mit Langstatorlinearmotorantrieb erreicht.The described method according to the invention is a safe one Keeping the distance even with magnetic levitation vehicles with long stator linear motor drive achieved.
