Abstract
Die Erfindung betrifft eine Vorrichtung zur Detektion des Belegt- oder Freizustandes eines Gleisabschnittes (1) mittels eines Gleisstromkreises, in den ein Sender (S; 8.S) an einem ersten Gleisanschlusspunkt (GA1, GA2, GA3) ein Sendesignal einspeist, welches über den Gleisstromkreis mindestens einem Empfänger (E1, E2; 8.E) an mindestens einem zweiten Gleisanschlusspunkt (GA1, GA2, GA3) zugeführt ist. Um auf Relaistechnik zur fahrtrichtungsabhängimpfängern (E1, E2) zu verbindenden Gleisanschlusspunkte (GA1, GA2, GA3) verzichten zu können, ist erfindungsgemäß vorgesehen, dass an den ersten und zweiten Gleisanschlusspunkten (GA1, GA2, GA3) Sender/Empfänger-Paare (8) angeschlossen sind, wobei eine Ansteuerschaltung zur fahrtrichtungsabhängigen Aktivierung eines Senders (8.S) und mindestens eines Empfängers (8.E) verschiedener Sender/Empfänger-Paare (8) vorgesehen ist.The invention relates to a device for detecting the occupied or free state of a track section (1) by means of a track circuit, into which a transmitter (S; 8.S) at a first track connection point (GA1, GA2, GA3) feeds a transmission signal, which via the Track circuit is fed to at least one receiver (E1, E2; 8.E) at at least one second track connection point (GA1, GA2, GA3). In order to be able to dispense with relay technology for track connection points (GA1, GA2, GA3) to be connected to the direction-of-travel receivers (E1, E2), the invention provides that transmitter / receiver pairs (8) are connected, a control circuit for the direction-dependent activation of a transmitter (8.S) and at least one receiver (8.E) of different transmitter / receiver pairs (8) is provided.
Description
Die Erfindung betrifft eine Vorrichtung zur Detektion des Belegt- oder Freizustandes eines Gleisabschnittes mittels eines Gleisstromkreises, in den ein Sender an einem ersten Gleisanschlusspunkt ein Sendesignal einspeist, welches über den Gleisstromkreis mindestens einem Empfänger an mindestens einem zweiten Gleisanschlusspunkt zugeführt ist.The invention relates to a device for detecting the busy or idle state of a track section by means of a track circuit, in which a transmitter feeds a transmission signal at a first track connection point, which is supplied via the track circuit at least one receiver at at least one second track connection point.
Das Grundprinzip der Detektion des Belegt- und Freizustandes des Gleisabschnittes, das gleichzeitig dazu geeignet ist, Informationen an ein Schienenfahrzeug zu übertragen, besteht darin, dass der Sender ein Sendesignal generiert, das über den Gleisstromkreis, der den Gleisabschnitt repräsentiert, an den Empfänger übertragen wird, wobei der Empfänger das Sendesignal interpretiert.The basic principle of detection of the busy and idle state of the track section, which is at the same time capable of transmitting information to a rail vehicle, is that the transmitter generates a transmission signal which is transmitted to the receiver via the track circuit representing the track section wherein the receiver interprets the transmission signal.
Bei der in
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung gattungsgemäßer Art anzugeben, welche auch ohne Relaistechnik eine sichere Überwachung und Informationsübertragung ermöglicht.The invention has for its object to provide a device of the generic type, which allows reliable monitoring and information transmission without relay technology.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass an den ersten und zweiten Gleisanschlusspunkten Sender/Empfänger-Paare angeschlossen sind, wobei eine Ansteuerschaltung zur fahrtrichtungsabhängigen Aktivierung eines Senders und mindestens eines Empfängers verschiedener Sender/Empfänger-Paare vorgesehen ist. Auf diese Weise sind Umschaltrelais entbehrlich, wodurch sich die Lebensdauer erhöht. Darüber hinaus entfällt auch die potentialgetrennte Ansteuerung. Statt dessen ist eine weniger aufwändige Ansteuerschaltung vorgesehen, welche lediglich die fahrtrichtungsabhängige Auswahl des Senders und mindestens eines Empfängers aus den Sender/Empfänger-Paaren vornimmt. Letztlich ergibt sich gegenüber der bekannten Relaisschaltung ein geringerer Platzbedarf verbunden mit Aufwands- und Kostenreduzierung.According to the invention the object is achieved in that at the first and second track connection points transmitter / receiver pairs are connected, wherein a drive circuit for the direction of travel-dependent activation of a transmitter and at least one receiver of different transmitter / receiver pairs is provided. In this way, changeover relays are unnecessary, which increases the life. In addition, the potential-separated control eliminates. Instead, a less complex drive circuit is provided, which makes only the direction of travel-dependent selection of the transmitter and at least one receiver from the transmitter / receiver pairs. Ultimately, compared to the known relay circuit results in a smaller footprint associated with effort and cost reduction.
Gemäß Anspruch 2 sind die Sender/Empfänger-Paare mit einer senderseitigen Übertragerwicklung und einer empfängerseitigen Übertragerwicklung ausgestattet, welche mit einer gemeinsamen gleisanschlussseitigen Übertragerwicklung zusammenwirken. Die gleisanschlussseitige Übertragerwicklung für den Empfänger ist damit quasi in die Übertragerwicklung für den Sender integriert. Dadurch ist für jedes Sender/Empfänger-Paar nur eine zusätzliche Wicklung erforderlich.According to
Nachfolgend wird die Erfindung anhand figürlicher Darstellungen näher beschrieben.The invention will be described in more detail with reference to figurative representations.
