Description

Verfahren zur gleichzeitigen Fernübertragung von mehreren Signalen mit Hochfrequenz Bei der Übertragung von Nachrichten mit Hilfe von Hochfrequenz längs Leitung hat man besondere Sperrelemente vorgesehen, welche den Übertritt der Hochfrequenzenergie in elektrische Apparate, z. B. Transformatoren, Ölschalter u. dgl., verhindern. Durch diese Sperrglieder werden meist einzelne Leitungsabschnitte gegen die Hochfrequenz abgeriegelt. Der Zweck dieser Maßnahme ist, Nebenschlüsse für die Höchfrequenzenergie, welche durch die elektrischen Apparate dargestellt werden, zu vermeiden. Damit die Hochfrequenzenergie sich aber längs der Leitung fortpflanzen kann, werden besondere für die zu übertragende Hochfrequenz durchlässige Überbrückungsglieder für die in die Leitung eingeschalteten Sperrelemente vorgesehen.Method for the simultaneous remote transmission of several signals with high frequency When transmitting messages with the help of high frequency along the line one has provided special locking elements which prevent the passage of the RF energy into electrical equipment, e.g. B. transformers, oil switches, etc. like., prevent. These blocking elements usually create individual line sections sealed off from the high frequency. The purpose of this measure is to shunts for the highest frequency energy represented by the electrical apparatus be to avoid. So that the high-frequency energy is along the line can propagate, are particularly permeable to the high frequency to be transmitted Bridging elements are provided for the blocking elements that are switched on in the line.

Man hat vorgeschlagen, Signale längs Hochspannungsleitung dadurch zu übertragen, daß man den Widerstand der erwähnten Überbrückungsglieder im Rhythmus der zu übertragenden Zeichen verändert und auf diese Weise eine Modulation der sich längs der Hochspannungsleitung ausbreitenden Hochfrequenzenergie herbeiführt. Gemäß der Erfindung kann man mit Hilfe einer solchen Einrichtung gleichzeitig mehrere Signale mit Hilfe von Hochfrequenz längs einer Leitung übertragen, wenn man für jede Trägerwelle besondere Überbrückungsglieder für die Sperrelemente in die Hochspannungsleitung einschaltet und den Widerstand der Überbrückungsglieder von dem zugeordneten Signalgeber beeinflußt. Zur Überbrückung der Sperrglieder kann man beispielsweise in Reihe geschaltete Kondensatoren und Induktivitäten verwenden, die auf je eine Trägerwelle abgestimmt sind.It has been proposed to pass signals along power lines to transfer that the resistance of the bridging links mentioned above can be met in rhythm of the characters to be transmitted changed and in this way a modulation of the itself brings about high frequency energy propagating along the high voltage line. According to the invention you can with the help of such a device at the same time several Transmit signals with the help of high frequency along a line if one for Each carrier wave has special bridging links for the blocking elements in the high-voltage line switches on and the resistance of the bridging elements from the associated signal generator influenced. To bypass the blocking elements, it is possible, for example, to connect them in series Use capacitors and inductors that are each matched to a carrier wave are.

Zur Ankopplung von Hochfrequenzsendern an Starkstrpmleitungen sowie zur Überbrükkung von Trennschaltern und Sperrelementen ist bereits vorgeschlagen worden, besondere Überbrückungsglieder für mehrere Trägerwellen zu verwenden. Bei diesen bekannten Anordnungen handelt es sich aber nicht darum, die Trägerwellen durch Ändern des Widerstandes der Überbrückungsglieder zu modulieren.For coupling high-frequency transmitters to power lines as well as for bridging disconnectors and blocking elements has already been proposed have been to use special bridging links for multiple carrier waves. at However, these known arrangements are not concerned with the carrier waves modulate by changing the resistance of the bridging links.
