Description
Impuls-Gleisstromkreissystem Die Erfindung bezieht sich auf ein Impuls-Gleisstromkreissystem. Pulse Track Circuit System The invention relates to a pulse track circuit system.
Es ist das Ziel der Erfindung, die Möglichkeit des Auftretens eines falschen Ansprechens auszuschließen.It is the aim of the invention to reduce the possibility of the occurrence of a to rule out incorrect response.
Mit einzelnem Sender und Empfänger ausgestattete Gleisstromkreissysteme sind bekannt. Bei diesen sind die einzelnen Gleisstromkreise nur durch die Qualität des übertragenen Signals, sei es hinsichtlich der Frequenz, Phase, Polarität, Kode, gegeneinander geschützt. Sie können aber auch durch einzelne zusätzliche Vorrichtungen gegeneinander geschützt sein.Track circuit systems equipped with a single transmitter and receiver are known. With these, the individual track circuits are only due to the quality of the transmitted signal, be it in terms of frequency, phase, polarity, code, protected against each other. But you can also by individual additional devices be protected against each other.
Die anteile dieser systeme besteigen in dem Bedarf einer vollständigen Sender- und Empfangeranlave für jeden einzelnen Gleisstromrreis des Systems.The proportions of these systems are increasing in the need for a complete one Transmitter and receiver anlave for each individual track circuit of the system.
Es sind weiter mit Wechselstromimpulsen gespeiste Gleisstromkreissysteme mit zentralem Generator, mit zwei Folgen und einem selbständigen Empfang bekannt, wobei die Gleisstromkrise durch zusätzliche Vorrichtungen gegeneinander geschützt sind.There are also track circuit systems fed with alternating current pulses with a central generator, known with two sequences and an independent reception, the track current crisis being protected from each other by additional devices are.
Diese Systeme weisen folgende Nachteile auf: Sie benötigen zusätzliche Schutzvorrichtungen; die Anzahl von zwei Folgen genügt nicht für einen hinreichenden Schutz.These systems have the following disadvantages: They require additional Guards; the number of two sequences is not enough for a sufficient one Protection.
Die vorliegende Erfindung beseitigt diese Nachteile.The present invention overcomes these disadvantages.
Die Erfindung besteht darin, daß das System aus einem zentralen Folgengenerator, welcher die Merkmale der gesendeten Signale und deren Erkennungsbedingungen beim Empfang für alle Gleisstromkreise des Systems festlegt, aus einem Leistungsimpulsformer und einem Impulsdetektor, der von einem elektronischen Relais gefolgt wird, besteht, die für die einzelnen Gleisstromkreise vom zentralen Folgengenerator aus synchronisiert werden.The invention consists in that the system consists of a central sequence generator, which the characteristics of the transmitted signals and their detection conditions at Receipt for all track circuits of the system from a power pulse shaper and a pulse detector followed by an electronic relay, which is synchronized for the individual track circuits from the central sequence generator will.
Das Wesen der Erfindung ist nachstehend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert. Es zeigen: Fig. 1 das Blockschema des Systems, Fig. 2 das Schema der Ausrüstung eines Gleisstromkreises im einzelnen.The essence of the invention is shown below with reference to one in the drawing schematically illustrated embodiment explained in more detail. Show it: Fig. 1 the block diagram of the system, FIG. 2 the diagram of the equipment of a track circuit in detail.
Gemäß der Erfindung steuert ein Schrittgeber-Oszillator 1 einen Ringzähler a, welcher an seinen sechs Ausgängen a, b, c, d, e, f Impulse mit der Wiederholunsperiode T, untereinander um T/6 zeitlich verschoben, erzeugt, wodurch sechs Folgen zustande komlnen. Diese Impulse werden weder einzelnen Anlage eines Gleisstromkreises 3, die auf der entsprechenden Folge arbeitet, direkt für die Steuerung des Sendet durch einen Anschluß g, und mittels einer monostabilen Schaltung 4 für die Synchronisierung des Empfängers, durch einen Anschluß h, zugeführt.According to the invention, a pacer oscillator 1 controls a ring counter a, which at its six outputs a, b, c, d, e, f pulses with the repetition period T, shifted in time by T / 6, resulting in six sequences come. These impulses are not used as an individual system in a track circuit 3, which works on the corresponding sequence, directly for the control of the transmits through a terminal g, and by means of a monostable circuit 4 for synchronization of the receiver through a port h.
Die einzelne Ausrüstung jedes Gleisstromkreises (Fig. 2) besteht aus einem Leistungsimpuls-Former 5, der Impulse in das Gleis sendet, einem Impuls-Diskriminator 6, einer Koinzidenz-Schaltung 7 und einem elektronischen Relais 8.The individual equipment of each track circuit (Fig. 2) consists of a power pulse shaper 5, which sends pulses into the track, a pulse discriminator 6, a coincidence circuit 7 and an electronic relay 8.
Die Ausgangs impulse des Impuls-Diskriminators 6 steuern das elektronische Relais 8 nur dann an, wenn die Koinzidenz-Schaltung 7 durch die monostabile Schaltung 4 von derselben Folge geöffnet wird. Das Eindringen von Impulsen aus einer fremden Folge in den betrachteten Gleisstromkreis kann nicht zum Ansprechen des elektronischen Relais 8 führen, da die Koinzidenz-Schaltung 7 das Durchdringen der Impulse sperrt.The output pulses of the pulse discriminator 6 control the electronic Relay 8 only on when the coincidence circuit 7 is through the monostable circuit 4 is opened by the same episode. The penetration of impulses from a strange person Result in the track circuit under consideration cannot trigger the electronic Relay 8 lead, since the coincidence circuit 7 blocks the penetration of the pulses.
Die beschriebene Erfindung weist folgende Vorteile auf: erhöhten Schutz gegen Störungen; erlaubt die Verwendung einer beliebig großen Anzahl von Folgen, die für den gegenseitigen Schutz der Gleisstromkreise des Systems nötig sind; die zu einem Gleisstromkreis gehörende Anlage ist erheblich vereinfacht; benötigt keine besondere Stabilität des Steueroszillators.The described invention has the following advantages: increased protection against disturbances; allows the use of an arbitrarily large number of sequences, which are necessary for the mutual protection of the track circuits of the system; the the system belonging to a track circuit is considerably simplified; does not need any particular stability of the control oscillator.
