Abstract
Description
Die Erfindung betrifft eine Induktionssicherung zur Sicherung des Eisenbahnverkehrs nach dem Oberbegriff des Anspruch 1.The invention relates to an induction fuse to secure rail traffic according to the preamble of the claim 1.
Eine derartige Induktionssicherung
ist z. B. bekannt durch die
In diesen Fällen hängt die Sicherheit des Schienenverkehrs von der ordnungsgemäßen Funktion der Induktionssicherung ab. Deshalb ist es erforderlich, in Zeitabständen die Induktionssicherung bei geschlossenem Haltesignal bzw. bei geschlossenem Stromkreis der Induktionssicherung mit einem Probefahrzeug zu überfahren, um die ordnungsgemäße Funktion der Induktionssicherung zu testen. Aufgabe der Endung ist es, diesen Aufwand zu ersparen und mit technisch einfachen Mitteln eine laufende oder regelmäßige oder auch willkürliche Überprüfung der Induktionssicherung zu ermöglichen oder vorzugsweise bei jeder Schaltung des Haltesignals bzw. des Stromkreises der Induktionssicherung die ordnungsgemäße Funktion der Induktionssicherung zu signalisieren und zu überprüfen.In these cases, the safety of rail traffic depends from the proper functioning the induction fuse. Therefore, it is necessary to periodically Induction protection when the stop signal is closed or when the circuit is closed to drive over the induction fuse with a test vehicle, for proper functioning to test the induction fuse. The task of the ending is this To save effort and with technically simple means an ongoing or regular or also arbitrary review of the To enable induction protection or preferably with each switching of the stop signal or the circuit the induction fuse the proper function of the induction fuse to signal and check.
Die Lösung ergibt sich aus Anspruch 1.The solution arises from claim 1.
Ein geeigneter Näherungsschalter ist z. B. in der
Derartige Näherungsschalter reagieren sehr empfindlich auf jede elektromagnetische Beeinflussung des Feldes ihrer Kontrollspule. Ihr Stromkreis enthält eine Messeinrichtung zur Messung einer geeigneten Kenngröße für die elektromagnetische Bedämpfung der Kontrollspule des Näherungsschalters, insbesondere des Stroms und/oder des Spannungsabfalls an einem Widerstand des Stromkreises.Such proximity switches are very sensitive to any electromagnetic interference in the field of your control coil. Your circuit contains a measuring device for measuring a suitable parameter for the electromagnetic attenuation the control coil of the proximity switch, in particular the current and / or the voltage drop across a resistor of the circuit.
Der Näherungsschalter ist nun in der Nähe der Spule der Induktionssicherung angeordnet und auf diese derart ausgerichtet, dass die Bedämpfung des Näherungsschalters sich abhängig davon ändert, ob der Stromkreis, in welchen die Spule der Induktionssicherung eingeschlossen ist, geöffnet oder geschossen ist. Daher kann durch Erfassung der Bedämpfung des Näherungsschalters auch festgestellt werden, ob der Stromkreis der Induktionssicherung geöffnet oder geschlossen ist, mit anderen Worten, ob der Schalter der Induktionssicherung funktioniert.The proximity switch is now in close to the Coil of the induction fuse arranged and aligned with it in such a way that dampening the Proximity switch become dependent of changes whether the circuit in which the coil of the induction fuse is opened or shot. Therefore, by detecting the damping of the Proximity switch also determine whether the circuit of the induction fuse is open or is closed, in other words whether the switch of the induction fuse works.
Der Schalter der Induktionssicherung kann z. B. durch Funksignal geöffnet und durch Feder geschlossen werden. Eine besonders häufige Anwendung findet die Induktionssicherung an Signalen, die – wie beschrieben – auf „Fahrt" oder „Halt" schaltbar sind. Hierbei ist die Schaltung des Signals synchronisiert mit dem Schalter des Stromkreises der Induktionssicherung. Damit ändert sich auch das Bedämpfungssignal des Näherungsschalters, das gleichzeitig im Stellwerk oder der sonstigen Steile, welche die Schaltung des Signals veranlast hat, ausgegeben werden kann. Es kann also eine unmittelbare Erfolgskontrolle bei der Stellung des Signals erfolgen.The switch of the induction fuse can e.g. B. opened by radio signal and be closed by spring. A particularly common application finds the induction fuse on signals that - as described - can be switched to "drive" or "stop". The circuit of the signal is synchronized with the switch the circuit of the induction fuse. This also changes the damping signal the proximity switch, at the same time in the signal box or other steep, which caused the switching of the signal, can be output. So there can be an immediate success check on the position of the signal.
Dabei kann die Schaltung des Signals auch außerhalb des Fahrbetriebes zu Testzwecken regelmäßig oder willkürlich erfolgen.The circuit of the signal also outside of the driving operation for test purposes take place regularly or arbitrarily.
Zur Überprüfung der ordnungsgemäßen Funktion der Induktionssicherung kann festgestellt werden, ob die Messeinrichtung bei Schaltung des Signals überhaupt reagiert.To check the correct function the induction fuse can determine whether the measuring device when switching the signal at all responding.
Vorzugsweise wird für den bedämpften Zustand des Näherungsschalters jedoch ein Sollwert ermittelt und festgesetzt. Bei Schließen des Stromkreises der Induktionssicherung bzw. Signalverstellung wird die Abweichung des Ist-Werts der Bedämpfung von dem Sollwert der Bedämpfung signalisiert. Überschreitet die Abweichung einen vorgegebenen Grenzwert, so dass die ordnungsgemäße Funktion der induktionssicherung und/oder des Signals und/oder der Näherungsschalters in Frage gestellt ist, wird der Fahrbetrieb eingeschränkt und eine Fehlerbehebung vor Ort durchgeführt.It is preferred for the damped state of the proximity switch however, a target value is determined and set. When closing the Circuit of the induction fuse or signal adjustment the deviation of the actual value of the damping from the nominal value of the attenuation signaled. exceeds the deviation is a predetermined limit, so that the proper functioning of the induction fuse and / or the signal and / or the proximity switch is questioned, driving is restricted and carried out a troubleshooting on site.
Ein Ausführungsbeispiel der Erfindung wird anhand einer Schemaskizze beschrieben.An embodiment of the invention is described using a schematic sketch.
