Description
Für die Fernsteuerung von Vorrichtungen der verschiedenen Arten, z. B. vonWeichen-und Signalantrieben bei Eisenbahnsicherungseinrichtungen oder bei Gleisfreimeldeanlagen, selbsttätigem Block usw., verwendet man vielfäch Kodeströme. Die bisher bekannten Kodeerzeuger arbeiten auf mechanischem Wege und sind vor allem infolge der Dauerbeanspruchung vielfach Störungen unterworfen, wie z. B. mechanischen Hemmungen, Kontaktabbrand usw, Die Erfindung beruht auf der Erkenntnis, daß ein im. Eisenbahnsicherungswesen vielfach für die Erzeugung von Blinklicht verwendetes Gerät sich für die Kodeerzeugung eignet; da es wesentlich weniger Störungen unterworfen ist.For remote control of devices of various types, e.g. B. of switches and signal drives for railway safety devices or at Track vacancy detection systems, automatic block, etc., one uses multiple code streams. The previously known code generators work mechanically and are above all Often subjected to disturbances as a result of long-term stress, such as B. mechanical Inhibitions, contact erosion, etc., The invention is based on the knowledge that a in the. Railway safety systems are widely used for generating flashing lights Device is suitable for code generation; since it is much less subject to interference is.
Gemäß der Erfindung wird für die Kodeerzeugung eine thermisch gesteuerte Quecksilbersäule verwendet. Hierfür läßt sich z. B. der im Eiseilbahnsicherungswesen vielfach verwendete Thermoblinker benutzen.According to the invention, a thermally controlled code generation is used Mercury used. For this, z. B. in the ice ropeway safety system use widely used thermal indicators.
Der Erfindungsgegenstand ist in der Zeichnung beispielsweise erläutert (Fig. i und 2).The subject matter of the invention is explained in the drawing, for example (Figs. I and 2).
Fig. i zeigt den einfachen Fall eines U-förmigen Gefäßes G, das mit Quecksilber Q gefüllt ist, wobei die Quecksilbersäule durch eine Heizwicklung Hin Bewegung gesetzt wird. Beim Anschalten z. B. mittels eines Kontakts K1, erhält die Heizwicklung H Strom, der Luftraum über der Quecksilbersäule wird erwärmt und verdrängt den Quecksilberspiegel Q1. So-bald der Quecksilberspiegel Q2 mit dem Kontaktstift K2 in Berührung tritt, wird der Stromkreis geschlossen, der von der Stromquelle über den Transformator T1 und den Blinker Q2, K2 zum Transformator T2 und über das Gleis G1 zum Relais 121 führt. ;Sobald die Quecksilbersäule so weit verdrängt ist, daß das untere Ende der Heizwicklung H aus dem Quecksilber auftaucht, schwingt die Quecksilbersäule zurück und unterbricht den Strom am Kontaktstift K2. Im nächsten Moment erhält die Heizwicklung H wieder Strom, die Quecksilbersäule sinkt usw.Fig. I shows the simple case of a U-shaped vessel G with Mercury Q is filled, with the mercury column being fed by a heating coil Hin Movement is set. When switching on z. B. by means of a contact K1, receives the Heating coil H current, the air space above the mercury column is heated and displaced the mercury level Q1. As soon as the mercury level Q2 with the contact pin K2 comes into contact, the circuit is closed by the power source via the transformer T1 and the blinker Q2, K2 to the transformer T2 and via the Track G1 leads to relay 121. ; As soon as the mercury column is displaced so far, that the lower end of the heating coil H emerges from the mercury, the oscillates Mercury back and interrupts the current at contact pin K2. In the next At the moment the heating coil H receives electricity again, the mercury column sinks, etc.
Man erhält also ein fortgesetztes Kontaktschließen und -unterbrechen.. Wenn man den Transformator T2 außer dem Kontaktstift K2 noch einen Kontaktstift K;, anschließt, der beim Zurückschwingen der Quecksilbersäule geschlossen wird, so erhält man einen weiteren Ködestroni, der gegenüber dem ersten verlagert ist.So you get a continued contact making and breaking .. If you have the transformer T2 in addition to the contact pin K2 also a contact pin K;, which is closed when the mercury column swings back, in this way one receives another Ködestroni, which is shifted from the first one.
Mit einer solchen Einrichtung kann man die verschiedensten Kombinationen von Kodeströmen erzeugen, d. h. also Stromstöße verschiedenerLänge. Man könnte z. B., wie angedeutet, noch einen weiteren Kontaktstift K4 vorsehen, der zu späterer Zeit in den Quecksilberspiegel eintaucht als der Stift K2, so daß also die Stromschlußzeit kürzer wäre als die von K2, wobei man dann nach Belieben den Korntakt K2 oder K4 anschließt. Man kann auch beide anschließen und hierdurch verschiedene Stromstärken erzeugen, z. B. wenn man dem Kontakt K2 einen Widerstand W1 vorschaltet. je nachdem, ob K2 wieder unterbrochen wird, ehe K3 unterbrochen wird, oder gleichzeitig oder später wie dieser, kann man ebenfalls verschiedene Kodequalitäten bekommen. Man kann auch zwei oder mehr Blinkgefäße vorsehen, in denen verschiedene Frequenzen erzeugt werden, wie z. B. in Fig. 2 dargestellt. Herbei können die beiden Gefäße G1 «und G2 entweder durch zwei Wicklungen H1 und H2 geheizt werden, oder beide Gefäße können miteinander verbunden sein; wie gestrichelt angedeutet, so daß die eine Quecksilbersäule die andere mitnimmt, wobei aber die Bewegungen beider Quecksilbersäulen gegeneinander phasenverschoben sind, so daß man also damit verschiedene Kodefrequenzen, erhält. Man kann :auch, wie dargestellt; den beiden Gefäßen G1 und G2 verschiedene Abmessungen= geben, wodurch die Schwingungsfrequenz der Quecksilbersäulen ebenfalls beeinflußt wird.With such a device you can make a wide variety of combinations generate code streams, d. H. that is, power surges of various lengths. One could e.g. B., as indicated, still provide another contact pin K4, the later Time immersed in the mercury level than the pin K2, so that the current cut-off time would be shorter than that of K2, whereby you can choose the grain cycle K2 or K4 connects. You can also connect both and thereby different currents generate, e.g. B. if you connect a resistor W1 upstream of the contact K2. depending on, whether K2 is interrupted again before K3 is interrupted, or at the same time or later like this one can also get different code qualities. Man can also provide two or more flashing vessels in which different frequencies are generated, such as B. shown in FIG. The two vessels can come by G1 «and G2 are either heated by two windings H1 and H2, or both vessels can be connected to each other; as indicated by dashed lines, so that the one column of mercury the other takes with it, but the movements of the two columns of mercury against each other are out of phase so that different code frequencies are thus obtained. You can: also, as shown; the two vessels G1 and G2 different dimensions = give, whereby the oscillation frequency of the mercury columns also affects will.
Aus den geschilderten Beispielen ist ersichtlich, daß der Thermoblinker geeignet ist, die verschie-'densten Kodeströme und Kodefrequenzen zu erzeugen. Gegenüber den bekannten Kodeerzeugern hat er den Vorteil, daß eine Abnutzung überhaupt nicht eintritt und die Störungsmöglichkeiten außerordentlich gering sind.From the examples described it can be seen that the thermal indicator is suitable for generating the most varied of code streams and code frequencies. Opposite to the known code generators it has the advantage that there is no wear at all occurs and the potential for disruption is extremely low.
