Patentiert im Deutschen Reiche vom 8. Januar 1929 abPatented in the German Empire on January 8, 1929
Die Erfindimg betrifft eine Einrichtung an Fernsprechanlagen mit Wahlanruf, insbesondere für Zugleitung, wie sie auch unter dem Namen Dispatching-System bekannt sind. Im allgemeinen bestehen solche Anlagen aus einer Hauptstelle und einer Reihe parallel an eine Doppelleitung angeschlossener Sprechstellen, die wechselseitig mit der Hauptstelle, nicht aber untereinander verkehren können.The invention relates to a device on telephone systems with dialing calls, in particular for train control, as they are also known as the dispatching system. In general such systems consist of a main unit and a number of microphone units connected in parallel to a double line, which can communicate with the main office, but not with one another.
Zum Anruf der Sprechstellen ist in der Hauptstelle ein Wähler angeordnet, der durch Drücken von Tasten zum Umlauf angereizt werden kann und dabei die den gedrückten Tasten entsprechenden Sprechstellen anruft. Jede dieser Sprechstellen enthält ein Schrittschaltwerk, welches unter Vermittlung von Linienrelais durch die vom Wähler ausgesandten Impulse fortgeschaltet wird. Ein Anruf kann nur dann richtig ankommen, wenn das Schaltwerk vor dem Ablauf in der Nullstellung steht.To call the microphone units, a selector is arranged in the main unit, which can be activated by pressing can be stimulated by keys to cycle and the corresponding to the pressed keys Call stations. Each of these call stations contains a step-by-step switch, which is mediated by line relays is advanced by the impulses sent by the voter. A call can only then arrive correctly when the switchgear is in the zero position before the end of the cycle.
Da für die Leitung meist Freileitungen verwendet werden, besteht die Gefahr, daß durch Blitzschläge oder andere Einflüsse Störenergien in die Leitung gelangen und sich in Form von Wanderwellen auf dieser ausbreiten. Dabei kommt es erfahrungsgemäß häufig vor, daß einzelne oder alle Schrittschaltwerke verstellt werden. Bei dem nächsten Umlauf der Wählers sind also Fehlanrufe wahrscheinlich. Erst nach Beendigung dieses Umlaufes sind die Schaltwerke wieder gleichgestellt, da sie in bekannter Weise durch Nullstellungskontakte in der Nullstellung festgehalten werden. Es muß also noch einmal gewählt werden, um die richtigen Verbindungen herzustellen. Dadurch ergeben sich Zeitverluste, die sehr nachteilig sein können.Since overhead lines are mostly used for the line, there is a risk that through Lightning strikes or other influences disturbance energies get into the line and take the form of Traveling waves propagate on this. Experience has shown that it often happens that individual or all stepping mechanisms can be adjusted. At the next round of the voter so wrong calls are likely. Only after the end of this cycle are the switching mechanisms equated again, since they are in the zero position in a known manner by zero position contacts be held. So it has to be chosen again to make the right connections to manufacture. This results in time losses which can be very disadvantageous.
Es besteht aber auch die Möglichkeit, daß ein für mehrere Sprechstellen bestimmter und daher gemeinsam übermittelter Befehl infolge Fehlanrufs von einzelnen der Sprechstellen nicht empfangen wird oder gar an falsche Sprechstellen gelangt, ohne daß man diesen Fehler sogleich in der Hauptstelle bemerkt. Gerade bei Zugleitungsanlagen können sehr unangenehme Folgen daraus entstehen.But there is also the possibility that one specific for several microphone units and therefore Jointly transmitted command not due to incorrect calls from individual call stations is received or even reaches the wrong microphone unit without this error immediately noticed in the main office. Especially with train line systems can be very uncomfortable Consequences arise from this.
Solche Fehlanrufe werden erfindungsgemäß dadurch vermieden, daß in der Hauptstelle eine selbsttätige Einrichtung vorgesehen ist, welche auf die in der Leitung auftretenden Störströme sicher anspricht und hierdurch die Gleichstellung aller, insbesondere der durch die Störung verstellten Schrittschaltwerke bewirkt. Zweckmäßig benutzt man ein besonderes, empfindliches Relais, welches an die Leitung angeschlossen wird und vorzugsweise in Gestalt eines Phasenrelais ausgebildet sein kann.Such false calls are avoided according to the invention that a Automatic device is provided which reacts to the interference currents occurring in the line responds safely and thereby equality for everyone, especially those disfigured by the disorder Stepping mechanisms causes. Appropriately one uses a special, sensitive one Relay, which is connected to the line and preferably in the form of a Phase relay can be formed.
Um die Gleichstellung herbeizuführen, ist es notwendig, eine Reihe von Impulsen in die Leitung zu senden, bis alle Schaltwerke die Nullstellung erreicht haben. Dazu kann irgend-In order to bring about equality, it is necessary to inject a series of impulses into the Send line until all switching mechanisms have reached the zero position. Any-
