Description

Anordnung zum Verhindern des Übersprechens von der Sendeleitung auf die Empfangsleitung bei mit Wechselstrom betriebenen Unterwasserschallanlagen Die Erfindung bezieht sich auf Unterwasserschallanlagen zur Aussendung und zum Empfang von Signalen, insbesondere auf solche Anlagen, bei denen die gleichen elektrisch betriebenen Schwinger zum Senden und Empfangen benutzt werden. Bei solchen Anlagen ist es notwendig, da8 ein Teil der zur Bedienung und Überwachung der Anlage nötigen Apparate und Instrumente, und zwar sowohl für Senden als für Empfang, in demselben Raum an Bord, der sogenannten Signalstation, vereinigt werden. Hieraus folgt, daß auch wechselstromführende Sendeleitungen gleichzeitig mit Empfangsleitungen in denselben Raum und gegebenenfalls sogar über dieselbe Schalttafel gelegt werden müssen. Andererseits muß aber die Anlage beim Umschalten von Empfang auf Senden sofort wieder betriebsklar sein, d. h. der zur Speisung der Sender dienende Wechselstromgenerator muß während des Empfanges weiterlaufen. Dabei zeigt sich, daß, auch wenn die Sender selbst von der Senderleitung abgeschaltet sind, doch ein außerordentlich starkes Übersprechen des Sendewechselstroms auf die Empfängsleitungen stattfindet, wodurch im Empfangstelephon ein dauernder stark störender Ton hervorgerufen wird.Arrangement for preventing crosstalk from the transmission line on the receiving line for underwater sound systems operated with alternating current The Invention relates to underwater sound systems for transmission and reception of signals, especially to those systems where the same electrical operated transducer can be used for sending and receiving. With such systems it is necessary that some of the necessary to operate and monitor the system Apparatus and instruments, both for sending and receiving, in the same Space on board, the so-called signal station. It follows from this that transmission lines carrying alternating currents at the same time as receiving lines in the same Space and possibly even have to be laid across the same control panel. on the other hand but the system must be operational again immediately when switching from reception to transmission be, d. H. the alternator used to power the transmitters must be used during continue to receive. It turns out that, even if the broadcasters themselves from the transmitter line are switched off, but an extremely strong crosstalk of the transmission alternating current takes place on the receiving lines, whereby in the receiving telephone a permanent, highly annoying sound is produced.

Gemäß der Erfindung begegnet man diesem Übelstand dadurch, daß beim Umschalten von Senden auf Empfang automatisch die Sendeleitung von dem Wechselstromgenerator abgeschaltet wird. Das Abschalten geschieht -zweckmäßig durch ein vom Sen.de-Empfangsschalter betätigtes Relais, welches einen möglichst nahe am Generator befindlichen Ausschalter betätigt.According to the invention, this drawback is countered by the fact that when Switching from transmit to receive automatically switches the transmit line from the alternator is switched off. The shutdown is done-expediently by one of the Sen.de reception desk actuated relay, which has a switch located as close as possible to the generator actuated.

In der Abbildung ist eine Anlage gemäß der Erfindung dargestellt. A -bezeichnet den Maschinenraum, in welchem der die Anlage speisende Motorgenerator aufgestellt ist. B ist die Signalstation und C der Raum, in welchem sich die eigentlichen Sende-Empfangsvibratoren befinden. Die Sendeleitung ist in der Abbildung punktiert, die Empfangsleitung schwach und alle Gleichstromleitungen sind stark ausgezogen.In the figure, a system according to the invention is shown. A - designates the engine room in which the motor generator feeding the system is set up. B is the signal station and C the room in which the actual Transmit / receive vibrators are located. The transmission line is dotted in the figure, the receiving line weak and all direct current lines are strongly drawn out.

Es bezeichnet zunächst im Maschinenraum i den Motor, 2 den Wechselstromgenerator der Anlage. Im Raum B befinden sich die Wechselstromsicherungen 3 und q., das Wattmeter 5, der Morsetaster 6 und die gesamte Empfangsanordnung, bestehend aus den Transformatoren 7 und 8, dem Verstärker 9, dem Sperrkondensator io und der Sperrdrossel i i sowie der Sende-Empfangsumschalter 12. Die Polarisationsbatterie 13 kann an beliebiger Stelle im Schiff untergebracht sein. 1q., 15 und 16 sind die Senderempfänger. In die Senderspeiseleitung ist nurr, zweckmäßig dicht am Umformer, ein Ausschalter 17 eingeschaltet, der durch das Relais i8 betätigt wird. Zur Speisung des Relais dient die Leitung r9, die durch den Kontaktarm 2o des Sende-Empfangsschalters 12 geöffnet und geschlossen wird. 'In der Stellung S (Senden) ist die Leitung i9 und somit die Wicklung des Relais' 18 stromlos und der Schalter 17 ist unter Wirkung der Feder 21 eingeschaltet. Beim Umlegen des Schalters 12 auf E (Empfang) erhält 18 Strom und schaltet die Senderspeiseleitungab.In the engine room i it first designates the engine, 2 the alternator the plant. The AC fuses 3 and q., The wattmeter are located in room B 5, the Morse code button 6 and the entire receiving arrangement, consisting of the transformers 7 and 8, the amplifier 9, the blocking capacitor io and the blocking reactor i i as well as the transmit / receive switch 12. The polarization battery 13 can be connected to any Place in the ship. 1q., 15 and 16 are the transceivers. In the transmitter feed line is only a switch, suitably close to the converter 17 switched on, which is actuated by relay i8. To feed the relay The line r9 is used, which is passed through the contact arm 2o of the transmit / receive switch 12 is opened and closed. 'In the position S (send) the line i9 and thus the winding of the relay '18 is de-energized and the switch 17 is active the spring 21 switched on. When the switch 12 is turned to E (receive) 18 Power and switches off the transmitter feed line.

Anstatt die Stellung »aus« am Schalter 17 durch das Relais 18 und die Stellung »ein« durch die Feder 21 zu erzielen, kann man auch umgekehrt verfahren.Instead of the "off" position on switch 17 through relay 18 and To achieve the "on" position by means of the spring 21, the reverse procedure can also be used.

Da es häufig erforderlich ist, Senderleitungen und Empfangsleitungen auch in anderen Räumen des Schiffes parallel oder benachbart zu verlegen, so ist es ratsam, das Abschaltrelais 17, 18 möglichst nahe an den Generator zu legen.-Since it is often necessary to have transmitter lines and receive lines is also to be laid in parallel or adjacent to other rooms of the ship it is advisable to place the switch-off relay 17, 18 as close as possible to the generator.
