Description
Verfahren zur induktiven Ubertragung der Stellung eines Streckensignales auf einen fahrenden Zug.
Bei ¯bertragungseinrichtungen in Bahn anlagen nach dem bekannten doppelten Ubertragungsverfahren befinden sich auf der Lokomotive zwei Elektromagnete, von denen einer, der sogenannte Sendemagnet, dauernd erregt ist. Die Wicklung des andern Magne tes, des sogenannten Empfangsmagnetes, ist mit einem Relais verbunden, welches die übertragene Stellung des Streckensignals dem
Führer auf bekannte Art hör-oder sichtbar macht, bezw. eine Bremsung einleiten kann.
Am Geleise befinden sich in der Nähe des
Streekensignals, dessen Stellung übertragen werden soll, ebenfalls zwei Elektromagnete, die so angeordnet sind, daB bei der Vorbei fahrt der Lokomotive an denselben in einem bestimmten Moment je ein Lokomotivmagnet und ein Geleisemagnet übereinander stehen.
Die Wicklungen der beiden Geleisemagnete sind miteinander elektrisch verbunden.
Der elektrische Vorgang bei geschlossenem Signal spielt sich beim fahrenden Zug wie folgt ab :
Der Lokomotiv-Sendemagnet induziert in dem ihm gegenüber befindlichen Geleise magnet einen Wechselstrom, welcher in den andern Geleisemagnet flieBt und dort ein
Magnetfeld erzeugt. Dieses induziert im Ifokomotiv-Empfangsmagnet einen zweiten
Wechselstrom, welcher das mit der Wicklung verbundene Empfangsrelais betätigt.
Es hat sich nun gezeigt, da¯ der im Lokomotiv-Empfangsmagnet induzierte
Strom besonders bei grossen Fahrtgeschwin digkeiten wesentlich verstärkt werden kann, wen die Stellung der vier Magnete so ge wählt wird, dass der auf der Lokomotive angeordnete Empfangsmagnet seinen ihm zugeordneten Geleisemagneten zeitlich später überfährt, als der Lokomotiv-Sendemagnet seinen ihm zugeordneten Geleisemagneten.
In der Zeichnung ist schematisch ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. 1 ist der Sendemagnet, 2 der Empfangsmagnet ; beide befinden sich a, uf der Lokomotive, räumlich voneinander getrennt. 3 und 4 sind die miteinander elek trisch verbundenen Geleisemagnete. 5 ist die auf der Lokomotive befindliche Stromquelle, welche zur Erregung des Sendemagnetes 1 dient und 6 ist das mit der Wicklung des Empfangsmagnetes verbundene Empfangsrelais. Die einzelnen Vorgänge bei der Übertragung sind bereits in der Einleitung kurz angegeben worden und können als bekannt vorausgesetzt werden.
Aus der Beschreibung ist ersichtlich, dass der Sende- und der Emp fangsmagnet nicht gleichzeitig, wie dies bis jetzt der Fall war, die Geleisemagnete befahren, sondern nacheinander, und zwar befährt zuerst der Sendemagnet seinen zuge hörigen Geleisemagneten, während der Empfangsmagnet zeitlich später über seinen zugehörigen Geleisemagneten fährt. Hierdurch hat das im Geleisemagneten 4 entstehende Magnetfeld genügend Zeit zu seinem voll- ständigen Aufbau. Der Empfangsmagnet 2 ? trifft in dem Fall ein bedeutend stärkeres Feld bei der Vorbeifahrt an. Infolgedessen ist der in dem Empfangsmagnet induzierte Strom wesentlich kräftiger, was sich besonders bei gro¯en Fahrtgesehwindigkeiten deut lich zeigt.
Method for the inductive transmission of the position of a line signal to a moving train.
In the case of transmission devices in railway systems using the well-known double transmission method, there are two electromagnets on the locomotive, one of which, the so-called transmitter magnet, is permanently excited. The winding of the other Magne tes, the so-called receiving magnet, is connected to a relay, which the transmitted position of the line signal to the
Leader in a known way audible or visible, respectively can initiate braking.
On the track are near the
Streekensignals, the position of which is to be transmitted, also have two electromagnets, which are arranged in such a way that when the locomotive passes it, a locomotive magnet and a track magnet are positioned one above the other at a certain moment.
The windings of the two track magnets are electrically connected to each other.
The electrical process when the signal is closed takes place as follows when the train is moving:
The locomotive transmitter magnet induces an alternating current in the track magnet opposite it, which flows into the other track magnet and enters there
Magnetic field generated. This induces a second magnet in the Ifokomotiv receiving magnet
Alternating current, which actuates the receiving relay connected to the winding.
It has now been shown that the induced in the locomotive receiving magnet
Electricity can be significantly increased, especially at high speeds, if the position of the four magnets is chosen so that the receiving magnet on the locomotive passes over its assigned track magnet later than the locomotive transmitter magnet's assigned track magnet.
An exemplary embodiment of the subject matter of the invention is shown schematically in the drawing. 1 is the transmitting magnet, 2 is the receiving magnet; both are on the locomotive, spatially separated from each other. 3 and 4 are the electrically interconnected track magnets. 5 is the power source located on the locomotive, which is used to excite the transmitting magnet 1 and 6 is the receiving relay connected to the winding of the receiving magnet. The individual processes involved in the transfer have already been briefly specified in the introduction and can be assumed to be known.
From the description it can be seen that the transmitting magnet and the receiving magnet do not travel the track magnets at the same time, as has been the case up to now, but one after the other, namely first the transmitting magnet drives its associated track magnet, while the receiving magnet later on its associated track magnet moves. As a result, the magnetic field created in the track magnet 4 has enough time to build up completely. The receiving magnet 2? In this case, a significantly stronger field is encountered when driving past. As a result, the current induced in the receiving magnet is much stronger, which is particularly evident at high speeds.
