Description

Anordnung zur Hörkontrolle eines Peilergebnisses in Verbindung niit fortlaufend rotierenden Empfangsorganen Es sind im Zusammenhang mit der direkten Anzeige von Peilungen Einrichtungen bekannt, bei denen ein richtempfindliches Organ kontinuierlich .schnell umläuft. Zur Aufzeichnung der -Peilkurve oder eines Teiles dieser Kurve rotiert mit dem richtempfindlichen Organ eine Aufzeichnungsvorrichtung. Gewöhnlich ist eine gleichzeitige Hörkontrolle der Peilung nicht erforderlich und ohne weiteres auch nicht möglich.Arrangement for auditory control of a bearing result in connection with continuously rotating receiving organs There are related to the direct Display of bearings facilities known where a direction sensitive organ continuously. rotates quickly. For recording the bearing curve or a part This curve rotates with the direction-sensitive organ a recording device. Simultaneous listening control of the bearing is usually not required and also not possible without further ado.

Es gibt jedoch Fälle, in denen eine Hörkontrolle gewünscht wird. Eine solche Kontrolle kann gemäß der vorliegenden Erfindung dadurch erfolgen, daß der übertragungskanal zwischen dem rotierenden Richtorgan und dem Abhörmittel normalerweise blockiert und nur beim Durchlaufen des Richtorgans durch den Bereich des Maximums oder Minimums mittels einex mit dem Richtorgan rotierenden, gegenüber diesem verstellbaren Kontakteinrichtung kurzzeitig aufgeriegelt wird.However, there are cases when hearing control is desired. One such control can be carried out according to the present invention in that the transmission channel between the rotating directional organ and the listening device normally blocked and only when passing the judge through the area of the maximum or minimum by means of one that rotates with the directional element and is adjustable in relation to it Contact device is temporarily unlocked.

Die erfindungsgemäße Anordnung ergibt eine Steigerung der Genauigkeit der optischen Anzeige durch die gleichzeitige Hörkontrolle. Diese Genauigkeit war mit den bisher bekannten Peilempfängern, bei denen beispielsweise beim Durchgang des richtempfindlichen Organs durch das Maximum oder Minimum eine Glimmlampe aufleuchtete, nicht erreichbar, da die Erregung der Glimmlampe von der Amplitude der einfallenden Spannungen sehr stark abhängig ist.The arrangement according to the invention results in an increase in accuracy the visual display through the simultaneous hearing control. That accuracy was with the previously known DF receivers, in which, for example, when passing through of the organ sensitive to direction lit up a glow lamp through the maximum or minimum, not achievable because the excitation of the glow lamp depends on the amplitude of the incident Tensions is very dependent.

Bei der -erfindungsgemäßen Anordnung wird der übertragungskanal zwischen dem rotierenden Richtorgan und,dem Abhörmittel nur beim Durchlaufen des Richtorgans durch bestimmt-- enge Sektoren von wenigen Grad Winkelbreite aufgeriegelt. Dazu sind gemäß der weiteren Erfindung Mittel vorgesehen, um die Richtung dieses Sektors einzustellen und um die Einstellung ablesen zu können.In the arrangement according to the invention, the transmission channel is between the rotating straightening organ and the listening device only when passing through the straightening organ through certain - narrow sectors of a few degrees angular width unlocked. In addition according to the further invention means are provided for the direction of this sector and to be able to read the setting.

Das Ohr nimmt dann stoßweise Impulse wahr, deren Frequenz von der Umlaufgeschwindigkeit des Richtorgans abhängt und bei bilateralen Einrichtungen gleich der doppelten Umlauffrequenz ist; die Stärke der Impulse hängt von der Frequenzenergie ab, die das Richtempfangsorgan bei der gewählten Ausrichtung des Abhörsektors liefert. Zweckmäßig wird dieser Sektor so eng gemacht, wie der größten zu erwartenden Schärfe eines Empfangsminimums oder -maximums entspricht; er kann auch veränderlich gemacht werden.The ear then perceives impulses in bursts, the frequency of which depends on the Circulation speed of the judge depends and with bilateral institutions is equal to twice the rotational frequency; the strength of the impulses depends on the frequency energy which the directional receiving organ delivers with the selected orientation of the listening sector. This sector is expediently made as narrow as the greatest expected sharpness corresponds to a reception minimum or maximum; it can also be made mutable will.

Welcher Art das Mittel ist, das die Bestimmung der Sektorrichtung und somit des Zeitpunktes der Aufriegelung innerhalb jeder Ümdrehung gestattet, ist für das Wesen der Erfindung gleichgültig. Es können z. B. Ohxnsche, kapazitive oder induktive Widerstände oder einfache Kontaktflächen aufeinander wirken, von denen der eine Teil mit dem Richtorgan umläuft, während der andere Teil auf einer Kreislinie einstellbar ist.What kind of means is used to determine the direction of the sector and thus the time of unlocking within each Turn permitted is irrelevant to the essence of the invention. It can e.g. B. Ohxnsche, capacitive or inductive resistances or simple contact surfaces interact, of which one part rotates with the judge, while the other part on a circular line is adjustable.

Die Wirkungsweise der Einrichtung wird an einem schematischen Beispiel gemäß der Abbildung erläutert. Darin bedeutet A eine dauernd rotierende Rahmenantenne, deren Ausgangsenergie über den Empfänger E sowohl einem Oszillographensystem O als auch über eine Verriegelungsvorrlchtung R denn Kopfhörer!< zugeführt wird. Die Oszillographenvorriehtung rotiert mit der Lichtquelle L synchron mit dem Rahmen und schreibt das Empfangsdiagramm auf den Bildschirm Sch der Anzeigevorrichtung.The mode of operation of the device is explained using a schematic example as shown in the figure. A means a continuously rotating loop antenna, the output energy of which is fed via the receiver E both to an oscilloscope system O and via a locking device R for headphones! <. The oscilloscope device rotates with the light source L in synchronism with the frame and writes the reception diagram on the screen Sch of the display device.

Die Verriegelungsvorrichtung f, sperrt normalerweise den Durchgang der Empfangs, energie von E nach 1(, mit Ausnahme derjenigen Stellung des Rahmens, in welcher die BürsteB Kontakt mit der leitenden Belegung der Kontaktscheibe IYI herstellt. In dieser Stellung wird dem Verriegelungsgäed R eine Entriegelungsspannung D zugeführt, welche die öffnung des Übertragungskanals E-1( bewirkt.The locking device f, normally blocks the passage the reception energy from E to 1 (, with the exception of the position of the frame, in which the brushB makes contact with the conductive assignment of the contact disk IYI manufactures. In this position, the locking device R is an unlocking voltage D supplied, which causes the opening of the transmission channel E-1 (.
