Description
Es sind Verfahren zur drahtlosen Telegrafie oder Telefonie mit einer Fernwirkung im Wasser bekannt, bei denen sowohl der Sender als auch der Empfänger ein oder zwei gekreuzte, ins Wasser getauchte Elektrodenpaare aufweisen, um ein Stromlinienfeld zu erzeugen bzw. zu empfangen. Insbesondere ist es bekannt, durch einen Sender mit einem Elektrodenpaar ein radialsymmetrisches Fernfeld zu erzeugen. There are methods for wireless telegraphy or telephony with a Action at a distance in the water known, in which both the transmitter and the receiver have one or two crossed pairs of electrodes immersed in water to achieve a To generate or receive streamline field. In particular, it is known by a transmitter with a pair of electrodes to generate a radially symmetrical far field.
Der Erfindung liegt die Aufgabe zugrunde, die Unterwasserpeilung eines durch zwei Elektroden erzeugten Stromlinienfeldes zu ermöglichen. The invention is based on the object of underwater direction finding to enable a streamline field generated by two electrodes.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwei Empfängerelektroden im Stromlinienfeld des Senders auf das Empfangsminimum eingestellt werden und als gesuchte Pejirichtung die Winkelhalbierende zwischen der durch die Verbindungslinie der Empfängerelektroden gcgebenen Richtung und der Richtung der Mittelsenkrechten auf der Verbindungslinie der Senderelektroden bestimmt wird. Die Meßausweftung kann bei diesem Verfahren gemäß einer Weiterbildung des Erfindungsgedankens durch eine Vorrichtung durchgeführt werden, die dadurch gekennzeichnet ist, daß an einem Kompaß Mittel vorgesehen sind, um die Mittelsenkrechte auf der in ihrer Richtung bekannten Verbindungslinie der Senderelektroden einzustellen und sie derart mit der Richtung der Verbindungslinie der Empfängerelektroden in 13eziehung zu setzen, daß die Winkelhalbierende ablesbar ist. This object is achieved according to the invention in that two receiver electrodes be set to the minimum reception in the streamlined field of the transmitter and as searched direction of the angle bisecting the line through the connecting line the direction given to the receiver electrodes and the direction of the perpendicular is determined on the connecting line of the transmitter electrodes. The measurement output can in this method according to a development of the inventive concept by a Device are carried out, which is characterized in that on a compass Means are provided for the perpendicular to the known in their direction Adjust the connecting line of the transmitter electrodes and align them with the direction to place the line connecting the receiver electrodes in a relationship that bisects the angle can be read.
Das erfindungsgemäße Verfahren und die zugehörige Vorrichtung ermöglichen z. 13. die geradlinige Führung eines Fahrzeuges auf den Sender, wenn die Lage der Senderelektroden in ihrer Richtung bekannt ist, oder gestattet es einem Unterwasserschwimmer, da die erforderliche Ausrüstung außerordentlich klein und leicht ist, sich zu orientieren, ohne daß er dazu gezwungen wird, aufzutauchen. . The method according to the invention and the associated device make it possible z. 13. the straight line guidance of a vehicle to the transmitter, if the location of the The direction of the transmitter electrodes is known, or allows an underwater swimmer to since the equipment required is extremely small and easy to orientate yourself, without being forced to show up. .
Die Erfindung sei im folgenden an Hand der beigefügten Zcichnung näher erläutert. Um die Senderelektroden A bildet sich das gezeigte Stromlinienfeld aus. Mit Hilfe eines nicht dargestellten Kompasses und eines Empfängerelektrodenpaares B, B ist es möglich, durch die Winkelhalbierende E zwischen der Senkrechten C auf der Verbindungslinie A-A der Senderelektroden bzw. der Parallelen C' zu dieser Senkrechten und der Richtung der Verbindungslinie B-B der Empfängerelektroden, die auf das Empfangsminimum eingestellt sind, die auf den Sender weisende Richtung festzustellen. The invention is described below with reference to the accompanying drawing explained in more detail. The streamlined field shown is formed around the transmitter electrodes A. the end. With the help of a compass (not shown) and a pair of receiver electrodes B, B it is possible to use the bisecting line E between the vertical line C. the connecting line A-A of the transmitter electrodes or the parallels C 'to this perpendicular and the direction of the connecting line B-B of the receiver electrodes, which point to the minimum reception are set to determine the direction facing the transmitter.
Hierfür wird beispielsweise eine Vorrichtung verwendet, die mit einem Kompaß und einem Richtungsanzeiger der Verbindungslinie B-B zwischen den Empfängerelektroden versehen ist. Am Kompaß ist die für die Senderelektroden charakteristische Richtung C fest einstellbar, beispielsweise durch einen Winkelschieber od. dgl. Dieser Schieber und der Richtungsanzeiger für die Stellung der Empfängerelektroden B, B sind so miteinander kombiniert, daß sie ständig einen Zeiger betätigen, der die Winkelhalbierende E zwischen der Verbindung B-B der Empfängerelektroden und der am Kompaß eingestellten Richtung C bzw. C' anzeigt. For this purpose, a device is used, for example, with a Compass and a direction indicator on the connecting line B-B between the receiver electrodes is provided. The direction characteristic for the transmitter electrodes is on the compass C permanently adjustable, for example by an angle slide or the like. This slide and the direction indicator for the position of the receiver electrodes B, B are like this combined with one another that they constantly operate a pointer that bisects the angle E between the connection B-B of the receiver electrodes and the one set on the compass Direction C or C 'indicates.
