Description
Es. ist bekannt, zur Richtungsbestimmung von Schallimpulsen den Zeitunterschied auszunutzen, mit dem der Impuls an zwei oder mehreren in festem Abstand voneinander angeordneter Empfängern eintritt, und ihn objektiv zur Anzeige zu bringen. Dabei wird die gesuchte Richtung aus den angezeigten Zeitdifferenzen rechnerisch oder graphisch ermittelt. It. it is known that the time difference is used to determine the direction of sound pulses take advantage of the momentum to two or more at a fixed distance from each other arranged recipients occurs, and bring him to the display objectively. Included the searched direction is calculated from the displayed time differences or determined graphically.
Das Wesen der Erfindung besteht darin, daß zur Erlangung einer objektiven kontinuierlichen Richtungsanzeige der Geschwindigkeitsvektor des Schallimpulses in zwei vorzugsweise unter 90° gekreuzte Teilvektorn zerlegt wird, indem man die Laufzeiten des Schallimpulses auf zwei unter 90° gekreuzten Strecken mißt und anschließend die beiden Teilvektoren bei der Anzeige sinngemäß zusammensetzt. Dadurch wird die Schallrichtung besonders anschaulich dargestellt und kann ohne weiteres abgelesen werden. The essence of the invention is that to obtain an objective continuous direction display of the velocity vector of the sound pulse is broken down into two partial vectors, preferably crossed at 90 °, by the Measures travel times of the sound pulse on two sections crossed at 90 ° and then the two sub-vectors are combined in the display accordingly. This will make the Direction of sound shown particularly clearly and can be read off easily will.
Die Erfindung sei an einem Ausführungsbeispiel veranschaulicht. The invention is illustrated using an exemplary embodiment.
Abb. 1 zeigt das Schaltbild einer Vorrichtung zur Richtungsbestimmung von Schallimpulsen, Abb. I a ein Vektorbild zu Abb. I. Fig. 1 shows the circuit diagram of a device for determining direction of sound pulses, Fig. I a a vector image for Fig. I.
Die Vorrichtung besteht im wesentlichen aus zwei Empfängerpaaren I, 2 und 3, 4, zwei Zeitmeßschaltungen zur Feststellung der zwischen Erregung der Empfänger I und 2 bzw. 3 und 4 durch einen einfallenden Impuls auftretenden Zeitdifferenzen und einem Braunschen Rohr 5 zur Anzeige der Richtung aus den beiden gemessenen Zeitdifferenzen. Wie aus Abb.. I a ersichtlich ist, wird durch die beiden um 90° gekreuzten Eimpfängerpaare der Geschwindigkeitsvektor des Schallimpulses in zwei Komponenten oder Teilvektoren zerlegt. Diese Komponenten können durch Messung der Laufzeiten t1,2 des Impulses zwischen den Empfängern I und 2 und t3,4 zwischen den Empfängern 3 und 4 ermittelt werden. Setzt man diese beiden Zeitvektoren zusammen, so ergibt sich, wie ohne weiteres ersichtlich ist, die wahre Richtung des einfallenden Schallimpulses, die durch den Vektor t dargestellt ist. Wenn somit die Zeiten t1,2 und t3,4 gemessen und als Ablenkspannungen den beiden Plattenpaaren des Braunschen Rohres 5 zugeführt werden, so kann an einer Kreisskala aus der Lage des Leuchtflecks 5a die genaue Richtung des Schallimpulses abgelesen werden. The device essentially consists of two pairs of receivers I, 2 and 3, 4, two timing circuits to determine the between excitation of the Receiver I and 2 or 3 and 4 time differences caused by an incident pulse and a Braun tube 5 for displaying the direction from the two measured time differences. As can be seen from Fig. I a, the two pairs of recipients crossed by 90 ° the velocity vector of the sound pulse in two components or sub-vectors disassembled. These components can be determined by measuring the transit times t1,2 of the pulse determined between receivers I and 2 and t3,4 between receivers 3 and 4 will. If you put these two time vectors together, the result is, without further ado what can be seen is the true direction of the incident sound pulse, which is caused by the Vector t is shown. Thus, if times t1,2 and t3,4 are measured and used as deflection voltages the two pairs of plates of the Braun tube 5 are fed, so can on one Circular scale from the position of the light spot 5a the exact direction of the sound pulse can be read.
Die Messung der Laufzeiten zwischen den Empfängern 1 und 2 und den Empfängern 3 und 4 geschieht durch zwei einander gleiche Schaltungsanordnungen, die folgendermaßen aufgebaut sind: Die Spannungsimpulse der Empfänger werden getrennt gittergesteuerten Gasentladungsstrecken 6, 7 bzw. 8, 9 zugeführt. Die Gasentladungsstrecken werden über einen gemeinsamen Anodenwiderstand 10 bzw. ii gespeist. Sie haben getrennte Kathoden widerstände I2, I3 bzw. 14, I5, denen über Wider stände 16, 17 bzw. I8, I9 Gasentladungsstrecken 20, 21 bzw. 22, 23 parallel geschaltet sind. Diese Gasentladungsstrecken liegen in Reihe mit Spannungsstabilisatoren 24, 25 bzw. 26, 27, die die Ladespannung für einen Zeitkreis, bestehend aus Kondensator 28, 29 bzw. 30, 31 und Widerstand 32; 33 bzw. 34, 35, liefern. Die Kondensatoren können durch einen Kontakt kurzgeschlossen und dadurch entladen, werden. The measurement of the transit times between receivers 1 and 2 and the Receivers 3 and 4 is done by two identical circuit arrangements, which are structured as follows: The voltage pulses from the receivers are separated grid-controlled gas discharge paths 6, 7 and 8, 9 respectively. The gas discharge paths are fed via a common anode resistor 10 or ii. They have separate Cathode resistors I2, I3 or 14, I5, which have resistors 16, 17 or I8, I9 gas discharge paths 20, 21 and 22, 23 are connected in parallel. These gas discharge paths are in series with voltage stabilizers 24, 25 and 26, 27, which control the charging voltage for a time circuit, consisting of capacitor 28, 29 or 30, 31 and resistor 32; 33 and 34, 35, respectively. The capacitors can be short-circuited by a contact and thereby be discharged.
Die Schaltung arbeitet folgendermaßen: Zündet der erste Impuls eines Empfängerpaares die zugehörige Gasentladungsstrecke, bei der angenommeinen Schallrichtung also der Spannungsimpuls des Empfängers 1 die Gasentladungsstrecke 6, so entsteht ein Spannungsabfall am Kathodenw-iderstand 12, der die Giimmstrecke 20, 24 zum Zünden bringt. Durch die Spannung an der Glimmstrecke 24 wird der Kondensator 28 über den Widerstand 32 allmählich aufgeladen. An der Aufladung des Kondensators 28 oder 29 kann die Reihenfolge der Impulse, an der Höhe der Aufladung die Zeitdifferenz zwischen den beiden Impulsen festgestellt werden. Zu diesem Zweck sind die beiden Kondenstatoren jeder Zeitmeßschaltung mit den bei-den Plattenpaaren des Braunschen Rohres verbunden, an dem dann aus dem Sinn der Leuchtfleekablenkung die Reihenfolge der Erregung bzw. der Sinn des Schalleinfalls und aus der Größe der Ablenkung die Zettdifferenz zu erkennen ist. Durch die zweite Zeitmeßschaltung wird die Zeitdifferenz zwischen den Empfängern 3, 4 in der gleichen Weise gemessen und als Ablenkspannung auf das andere Plattenpaar des Braunschen Rohres gegeben, so daß die resultierende Ablenkung des Leuchtflecks 5a dem Vektor t (Abb. 1 a) bzw. der Einfallsrichtung des Schalles entspricht. The circuit works as follows: The first pulse ignites one Receiver pair the associated gas discharge path, with the assumed direction of sound so the voltage pulse of the receiver 1, the gas discharge path 6, so arises a voltage drop across the cathode resistor 12, which causes the gap 20, 24 to ignite brings. Due to the voltage at the glow path 24, the capacitor 28 is on the Resistor 32 gradually charged. On the charging of the capacitor 28 or 29 can be the order of the pulses, at the level of charge the time difference between the two pulses can be determined. For this purpose the two capacitors are each timing circuit is connected to the two pairs of plates of the Braun tube, on which the sequence of excitation resp. the meaning of the sound incidence and the Zett difference from the size of the deflection recognize is. By the second time measuring circuit, the time difference between the receivers 3, 4 measured in the same way and applied as deflection voltage to the given another pair of Braun's tube plates, so that the resulting deflection of the light spot 5a to the vector t (Fig. 1 a) or the direction of incidence of the sound is equivalent to.
Die Erfindung ist nicht auf die dargestellten Beispiele beschränkt, vielmehr sind noch mancherlei Ab änderungen und auch andere Ausführungen möglich, insbesondere können zur Zeitmessung auch andere Schaltungen verwendet werden. The invention is not limited to the examples shown, rather, many changes and other designs are still possible, in particular, other circuits can also be used for time measurement.
