Abstract

The apparatus for estimating the shots on a target is provided with two optical sensors (1, 3). One sensor is held at a fixed location of the trajectory of a target and allows the apparatus to determine the distance from the hole to the center of the target in the moving direction of the target (18). The other sensor is fixed to a transversal slide (38) which is movable perpendicularly to the moving direction of the target and measures the distance from the hole to the center of the target in a transversal direction. The two distance vectors are added vectorially by an appropriate calculator and multiplied by a rating factor. The result of the measurement may then be indicated as one tenth of a ring, printed or supplied to an information processing unit.

Description

Beim Leistungsschiessen werden Schiessscheiben verwendet, die eine Anzahl konzentrischer Ringe und im Mittelbereich einen dunklen Spiegel aufweisen. Der Abstand des Einschussloches von der Spiegelmitte wird mit dem Auge bestimmt.Shooting targets with a number of concentric rings and a dark mirror in the central area are used for performance shooting. The distance between the bullet hole and the center of the mirror is determined by the eye.

Aus der DE-A-1 703 171 sind ein gattungsgemässes Verfahren und eine Vorrichtung bekannt. Diese weisen zwei orthogonale Lichtschrankensysteme mit je 200 in gleichem Abstand voneinander angeordneten Lichtsendern und Empfängern auf. Die durchfliegenden Geschosse unterbrechen die fotoelektrischen Lichtschranken und die entsprechenden Koordinaten werden über eine Speicheranordnung und eine Abfrageanordnung zu einer Anzeigeanordnung übertragen.A generic method and a device are known from DE-A-1 703 171. These have two orthogonal light barrier systems, each with 200 light transmitters and receivers arranged at the same distance from each other. The projectiles flying through interrupt the photoelectric light barriers and the corresponding coordinates are transmitted to a display arrangement via a memory arrangement and a query arrangement.

Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung zur automatischen Trefferauswertung von Schiessscheiben zu schaffen, um subjektive Messfehler zu vermeiden, die Auswertegenauigkeit zu verbessern und die Auswertzeit herabzusetzen.The object of the invention is to create a method and a device for automatic hit evaluation of shooting targets in order to avoid subjective measurement errors, to improve the evaluation accuracy and to reduce the evaluation time.

Die Erfindung besteht hinsichtlich Verfahren und Vorrichtung prinzipiell darin, dass eine Einzelscheibe oder ein Scheibenband ein erstes Lichtschrankensystem durchläuft, welches in Bandlaufrichtung x ein Lochmittensignal Lx und ein Spiegelmittensignal Sx erzeugt. Vom Bandantrieb werden dem Bandvorschub proportionale Wegimpulssignale Ix erzeugt. Durch eine Impulstorschaltung wird nur diejenige Wegimpulsrate hindurchgelassen, welche zwischen dem Entstehen der Signale Lx und Sx auftritt. Aus der Zahl dieser Wegimpulse wird die Wegimpulssumme X gebildet. Ein zweites, dem ersten Lichtschrankensystem entsprechendes und rechtwinklig zu diesem angeordnetes Lichtschrankensystem wird relativ zur Schiessscheibe quer zu dessen Förderrichtung bewegt und es werden in entsprechender Weise die Wegimpulse in Richtung y dieser Querbewegung zwischen dem Entstehen eines Lochmittensignals Ly und eines Spiegelmittensignals Sy addiert und als Summenwert Y gespeichert. Die Werte X und Y werden einem Vektorrechner zugeführt, weicher den Term r = bildet, wobei r proportional zur Entfernung Schusslochmitte-Spiegelmitte ist. Dieser Wert r wird mit einem einstellbaren Eichfaktor multipliziert. Das Ergebnis wird als Ringzahlenwert z.B. mit 10te1 Teilung angezeigt und/oder einem Drucker bzw. einer EDV-Anlage zugeführt.With regard to the method and device, the invention basically consists in the fact that a single disk or a disk belt runs through a first light barrier system, which generates a hole center signal Lx and a mirror center signal Sx in the direction of belt travel x. The belt drive generates path pulse signals Ix proportional to the belt feed. Only the path pulse rate that occurs between the generation of the signals Lx and Sx is passed through a pulse gate circuit. The path pulse sum X is formed from the number of these path pulses. A second light barrier system, which corresponds to the first light barrier system and is arranged at right angles to the latter, is moved transversely to the conveying direction relative to the shooting target, and the path impulses in the direction y of this transverse movement between the formation of a hole center signal Ly and a mirror center signal Sy are added and as a total value Y saved. The values X and Y are fed to a vector computer which forms the term r =, where r is proportional to the distance from the center of the shot hole to the center of the mirror. This value r is multiplied by an adjustable calibration factor. The result is given as a ring number value e.g. displayed with 10te1 division and / or fed to a printer or an EDP system.

Die jeweiligen Mittensignale werden durch Abfühlen der gegenüberliegenden Randsignale ermittelt. Dadurch wird eine im Vergleich zur manuellen Auswertung 10mal grössere Auswertegenauigkeit erreicht und die Auswertzeit beträgt nur etwa 1 Sekunde.The respective center signals are determined by sensing the opposite edge signals. As a result, the evaluation accuracy is 10 times greater than that of manual evaluation and the evaluation time is only about 1 second.

Das Schiessscheiben-Auswertgerät besteht aus einem prismatischen Gehäuse 14 mit einem sich verjüngenden Einlassspalt 22 an der Vorderseite und einem Auslassspalt 16 an der gegenüberliegenden Gehäusewand. Ein Schiessscheibenband 18, das mehrere Scheiben mit äusseren Ringen und innerem Spiegel 20 enthält, wird in den Spalt 22 eingeschoben und passiert, nachdem es von einem Einzugsrollenpaar 24, 26 erfasst wird nacheinander zwei Lichtschrankensysteme 1 und 3 zwischen denen ein zweites Rollenpaar 28, 30 angeordnet ist, um auch Einzelscheiben auswerten zu können. Die Rolle 28 wird direkt von einem Antriebsmotor 36 angetrieben, der an einem Schrittimpulsgeber 2 angeschlossen ist. Beide Rollen 24, 28 der Rollenpaare tragen Zahnräder 31, 32 und sind durch einen Zahnriemen 34 synchronisiert.The shooting target evaluation unit consists of a prismatic housing 14 with a tapering inlet gap 22 on the front and an outlet gap 16 on the opposite housing wall. A shooting target belt 18, which contains a plurality of targets with outer rings and inner mirror 20, is inserted into the gap 22 and, after it has been caught by a pair of feed rollers 24, 26, two light barrier systems 1 and 3 are successively arranged between which a second pair of rollers 28, 30 is in order to be able to evaluate single slices. The roller 28 is driven directly by a drive motor 36 which is connected to a step pulse generator 2. Both rollers 24, 28 of the roller pairs carry gear wheels 31, 32 and are synchronized by a toothed belt 34.

Das zweite Lichtschrankensystem 3'ist auf einem querverfahrbaren Schlitten 38 angeordnet, der aus einer oberen Platte 40 und einer unteren Platte 42' besteht, die beide unabhängig voneinander an gehäusefesten Führungsstangen 42, 44 bzw. 46, 48 verschiebbar geführt sind. Ausserhalb der Bewegungsbahn des Scheibenbandes 18 ist auf der einen Seite eine vertikale Antriebswelle 50 und auf der anderen Seite eine Umlenkwelle 52 drehbar gelagert. Beide Wellen tragen obere und untere Zahnräder 54, 56. Die beiden oberen Zahnräder 54, 54 und die beiden unteren Zahnräder 56, 56 werden jeweils durch einen Zahnriemen 58 bzw. 60 umschlungen. Die Antriebswelle 50 ist direkt mit einem Antriebsmotor 62 verbunden, der ebenfalls einen Schrittimpulsgeber 4 (Fig. 5) aufweist. Der Motor 62 ist umsteuerbar. Beide Zahnriemen 58, 60 weisen Mitnehmerstifte 64, 66 auf, die in entsprechende Bohrungen der Platten 50, 42' eingreifen, so dass diese vom Motor 62 abwechselnd in entgegengesetzten Richtungen quer über die Vorschubbahn des Bandes 18 hin- und herbewegt werden können.The second light barrier system 3 ' is arranged on a cross-movable carriage 38, which consists of an upper plate 40 and a lower plate 42', both of which are displaceably guided independently of one another on housing-fixed guide rods 42, 44 and 46, 48, respectively. Outside the path of movement of the disc belt 18, a vertical drive shaft 50 is rotatably supported on one side and a deflection shaft 52 on the other side. Both shafts carry upper and lower gear wheels 54, 56. The two upper gear wheels 54, 54 and the two lower gear wheels 56, 56 are each wrapped by a toothed belt 58 and 60, respectively. The drive shaft 50 is connected directly to a drive motor 62, which also has a step pulse generator 4 (FIG. 5). The motor 62 can be reversed. Both toothed belts 58, 60 have driver pins 64, 66 which engage in corresponding bores in the plates 50, 42 ', so that the motor 62 can alternately reciprocate them in opposite directions across the feed path of the belt 18.

Das Lichtschrankensystem 1 enthält eine obere Platte 68 und eine untere Platte 70, die beide gleich gross sind und sich quer über das Scheibenband 18 erstrecken. Die Länge der Platten ist mindestens gleich dem Durchmesser des grössten Scheibenringes. Beide Platten 68, 70 haben von der Bewegungsebene des Bandes 18 etwa den gleichen Abstand, der etwa das 2- bis 5fache des Durchmessers eines Einschussloches 72 beträgt. An der Unterseite der Oberplatte 68 sind im Querabstand etwa gleich dem doppelten Durchmesser des Einschussloches zwei über im wesentlichen die gesamte Länge der Platte 68 reichende Fototransistorzeilen 74, 76 angeordnet. In der vertikalen Symmetrieebene 78 zu diesen beiden Zeilen 74, 76 ist auf der unteren Platte 70 eine aus einer Vielzahl dicht nebeneinanderliegender Dioden bzw. Transistoren bestehende Lichtsendezeile 80 angeordnet.The light barrier system 1 contains an upper plate 68 and a lower plate 70, both of which are of the same size and extend across the disc band 18. The length of the plates is at least equal to the diameter of the largest disc ring. Both plates 68, 70 are at approximately the same distance from the plane of movement of the belt 18, which is approximately 2 to 5 times the diameter of a bullet hole 72. On the underside of the top plate 68, at a transverse distance approximately equal to twice the diameter of the bullet hole, two photo transistor lines 74, 76 extending over essentially the entire length of the plate 68 are arranged. Arranged in the vertical plane of symmetry 78 to these two lines 74, 76 on the lower plate 70 is a light emitting line 80 consisting of a plurality of diodes or transistors lying close together.

Bei der Bewegung des Bandes 18 in Richtung des Pfeiles 82 erhält zuerst die Empfängerzeile 74 durch das Schussloch 72 Licht von der Sendezeile 80. Sobald beide Empfängerzeilen 74, 76 die gleiche Helligkeit empfangen, wird über eine an sich bekannte Komparatorschaltung ein Signal Lx, das sogenannte Lochmittensignal für Bewegung in Bandförderrichtung erzeugt.When the band 18 moves in the direction of the arrow 82, the receiver line 74 first receives light from the transmission line 80 through the shot hole 72 as soon as both receiver lines 74, 76 receive the same brightness, a signal Lx, the so-called punch center signal for movement in the belt conveying direction, is generated via a comparator circuit known per se.

Auf ähnliche Weise wie das Lochmittensignai Lx wird im Lichtschrankensystem 1 ein Signal Sx ausgelöst, wenn bei vorbewegtem Scheibenband 18 die Mitte des Spiegels 20 die Vertikalebene 78 erreicht. Zu diesem Zweck sind an der Unterseite der Oberplatte 68 - in Förderrichtung hintereinanderliegend und im Abstand etwa gleich im Durchmesser eines Scheibenspiegels 20 zwei Reflexionslichtschranken 84, 86 angeordnet, die nicht zeilenförmig sondern knopfförmig ausgebildet sind und je aus einem Lichtsender und einem integrierten Lichtempfänger bestehen. Da der Scheibenspiegel schwarz und seine äussere Umgebung weiss ist, empfängt bei der Stellung des Scheibenspiegels 20 in Fig. 3 die Reflexionslichtschranken 86 mehr Licht als die Lichtschranke 84, da von der weissen Fläche mehr Licht reflektiert wird. Durchläuft also der Spiegel 20 das Lichtschrankenpaar 84, 86, so erhalten beide Lichtschranken 84, 86 gleiche Helligkeit, wenn sich der Spiegel 20 links von der in Fig. 3 dargestellten Stellung befindet. Der Empfang gleicher Helligkeitswerte in den Lichtschranken 84, 86 wird wiederum in einer Komparatorschaltung zu dem genannten Spiegelmittensignal Sx verarbeitet.In a manner similar to the hole center signal Lx, a signal Sx is triggered in the light barrier system 1 when the center of the mirror 20 reaches the vertical plane 78 with the pane belt 18 moved forward. For this purpose, two reflective light barriers 84, 86 are arranged on the underside of the top plate 68 - one behind the other in the conveying direction and at a distance approximately the same as the diameter of a disk mirror 20, which are not linear but button-shaped and each consist of a light transmitter and an integrated light receiver. Since the disk mirror is black and its outer surroundings are white, the reflection light barriers 86 receive more light than the light barrier 84 when the disk mirror 20 is in FIG. 3, since more light is reflected by the white surface. Thus, when the mirror 20 passes through the pair of light barriers 84, 86, both light barriers 84, 86 receive the same brightness when the mirror 20 is to the left of the position shown in FIG. 3. The reception of the same brightness values in the light barriers 84, 86 is in turn processed in a comparator circuit to the mirror center signal Sx mentioned.

Die beiden Reflexionslichtschranken 84, 86 könnten in der mittleren vertikalen Längsebene der Bandförderbahn angeordnet sein. Besser ist jedoch die Verwendung eines zweiten Reflexionslichtschrankenpaares 88, 90, das dem ersten Lichtschrankenpaar 84, 86 entspricht, wobei das eine Schrankenpaar auf der einen Seite und das andere Paar auf der anderen Seite von dieser vertikalen Längsmittelebene angeordnet ist. Zusätzlich ist jedem der vier Reflexionslichtschranken 84 - 90 ein Fototransistor 92 bzw. 94 in Verlängerung des Lichtsendestrahls auf der Oberseite der unteren Platte 70 des Lichtschrankensystems 1 zugeordnet. Wenn nämlich das Schussloch 72 im Hellgebiet desjenigen Spiegelrandbereiches liegt, weiches sein diffus reflektiertes Licht zu den Empfängern der Reflexionslichtschranken 84, 86 zurücksenden soll, so kann ein fehlerhaftes Spiegelmittensignal entstehen. Dies wird dadurch vermieden, dass von einem Schussloch 72 im Reflexionsbereich von den Lichtschranken 84, 86 durchgelassenes Licht zu dem darunterliegenden Empfänger 92 bzw. 92 gelangt und damit ein Signal erzeugt, weiches das Lochmittensignal dieser beiden Lichtschranken 84, 86 unterdrückt und auf das Spiegelmittensignal Sx des anderen, vom Schussloch freien Spiegelrandgebiet betriebenen Reflexionsiichtschrankenpaares 88, 90 umschaltet.The two reflection light barriers 84, 86 could be arranged in the central vertical longitudinal plane of the belt conveyor track. However, it is better to use a second pair of retro-reflective sensors 88, 90, which corresponds to the first pair of light-barriers 84, 86, one pair of barriers being arranged on one side and the other pair on the other side of this vertical longitudinal center plane. In addition, each of the four reflection light barriers 84-90 is assigned a phototransistor 92 and 94, respectively, in the extension of the light emission beam on the upper side of the lower plate 70 of the light barrier system 1. If, in fact, the shot hole 72 lies in the bright area of the mirror edge region which its diffusely reflected light is intended to send back to the receivers of the reflection light barriers 84, 86, then a faulty mirror center signal can arise. This is avoided by the fact that light transmitted through a shot hole 72 in the reflection area from the light barriers 84, 86 reaches the receiver 92 or 92 underneath and thus generates a signal which suppresses the hole center signal of these two light barriers 84, 86 and on the mirror center signal Sx of the other pair of reflection light barriers 88, 90 operated free from the shot hole area of the mirror edge.

Das Lichtschrankensystem 3 entspricht genau dem System 1. Es ist jedoch um 90° verdreht am Querschlitten 38 befestigt. Nachdem beim Durchgang eines Schiessscheibenspiegels 20 durch das Lichtschrankensystem 1 das Spiegelmittensignal Sx erzeugt ist, wird der Motor 36 in dem Moment angehalten, indem nach Zählung der Schrittimpulszahl die Spiegelmitte etwa die mittlere vertikale Querebene 96 des Querschlittens 38 erreicht hat. Damit läuft der Motor 62 an und bewegt den Querschlitten 38 rechtwinklig zur Förderrichtung des Bandes 18 um einen Betrag, der mindestens gleich dem äusseren Durchmesser der Schiessscheibe ist. In diesem Lichtschrankensystem 3 werden analog zum System 1 das Scheibenmittensignal Sy und das Schussloch-Mittensignal Ly erzeugt. Die beiden Impulsgeber 2 und 4 der Motoren 36 und 62 liefern während der Motorenlaufzeiten laufend Impulse Ix und ly.The light barrier system 3 corresponds exactly to the system 1. However, it is fastened to the cross slide 38 rotated by 90 °. After the mirror center signal Sx has been generated when a shooting disk mirror 20 passes through the light barrier system 1, the motor 36 is stopped at the moment in which, after counting the number of step pulses, the mirror center has approximately reached the central vertical transverse plane 96 of the cross slide 38. The motor 62 thus starts and moves the cross slide 38 perpendicular to the conveying direction of the belt 18 by an amount which is at least equal to the outer diameter of the target. In this light barrier system 3, the pane center signal Sy and the shot hole center signal Ly are generated analogously to the system 1. The two pulse generators 2 and 4 of the motors 36 and 62 continuously supply pulses Ix and ly during the motor running times.

Das Wegimpulssignal [x, das Lochmittensignal Lx und das Spiegelmittensignal Sx werden einer Impulstorschaltung 5 zugeführt, wobei mit Hilfe des Signalpaares Lx/Sx nur diejenige Impulsrate hindurchgelassen wird, welche der x-Koordinate zwischen Lochmitte und Spiegelmitte entspricht. Entsprechend wird aus den Signalen Sy, Ly und ly in einer Torschaltung 6 die y-Koordinate dieser Mittenabstände ermittelt. Die durchgelassenen Impulsraten x werden in einem Speicherzählwerk 7 gezählt und zwischengespeichert. Die durchgelassenen lmpulsraten y werden entsprechend im Zählerspeicher 8 verarbeitet. Die lmpulssumme X und die Impulssumme Y aus den Speichern 7, 8 werden einem Vektorrechner 9 zugeführt, welcher aus den Werten X und Y den Term r = errechnet. Der Wert r ist damit proportional zur Entfernung zwischen Schusslochmitte und Spiegelmitte. Das r-Signal wird durch Multiplikation mit einem einstellbaren Eichfaktor und Dekodierung in der Schaltung 10 zum Ringzahlenwert z.B. mit 10te1 Teilung als Messergebnis aufbereitet und einem Drucker 11 oder einer EDV-Anlage 12 zugeleitet. Der Drucker 11 kann ein Zähldrucker sein, welcher die Messergebnisse (Ringzahlenwerte) in den einzelnen Scheiben des Bandes 19 aufaddiert.The path pulse signal [x, the hole center signal Lx and the mirror center signal Sx are fed to a pulse gate circuit 5, with the aid of the signal pair Lx / Sx only the pulse rate which corresponds to the x coordinate between the hole center and the mirror center is passed through. Accordingly, the y coordinate of these center distances is determined from the signals Sy, Ly and ly in a gate circuit 6. The transmitted pulse rates x are counted in a memory counter 7 and buffered. The transmitted pulse rates y are processed accordingly in the counter memory 8. The pulse sum X and the pulse sum Y from the memories 7, 8 are fed to a vector computer 9 which calculates the term r = from the values X and Y. The value r is therefore proportional to the distance between the center of the shot hole and the center of the mirror. The r signal is processed by multiplication with an adjustable calibration factor and decoding in the circuit 10 to the ring number value, for example with a 10te1 division as the measurement result, and is sent to a printer 11 or a computer system 12. The printer 11 can be a counter printer, which adds up the measurement results (ring number values) in the individual slices of the belt 19.

Eine gedrängtere Bauweise und eine montageunabhängige Rechtwinkligkeit der Lichtschrankenzeilen 74, 76 beider Systeme 1, 3 werden erzielt, wenn beide Lichtschrankensysteme 1, 3 auf dem Querschlitten 38 angeordnet werden, der dann während der Ermittlung der x-Signale stillstehen muss. Allerdings kann dann nur die Schlittenbewegung in einer Richtung zur Messung genutzt werden.A more compact design and an assembly-independent perpendicularity of the light barrier rows 74, 76 of both systems 1, 3 are achieved if both light barrier systems 1, 3 are arranged on the cross slide 38, which must then stand still during the determination of the x signals. However, only the carriage movement in one direction can then be used for the measurement.

Eine alternative Ausführungsform für die Lichtschrankensysteme 1, 3 besteht darin, dass zur Ermittlung der Lochrandsignale die Fototransistorzeile 76 entfällt und die verbleibende Fototransistorzeile 74 mit der Lichtsendezeile 80 vertikal ausgerichtet wird. Wird ein vorgegebener Ansprechpegei an einem Lochrand erreicht, werden die Wegimpulsrate des Scheibenbandes bzw. des Schlittens gezählt bis derselbe Ansprechpegel am gegenüberliegenden Lochrand erreicht ist. Durch Halbierung der Wegimpulsrate wird die Lochmitte ermittelt. Entsprechend wird vorteilhafterweise bei der Ermittlung des Spiegelmittensignals verfahren. Das in Vorschubrichtung der Schiessscheibe 18 bzw. des Schlittens 38 jeweils hinter dem Paar Fototransistorzeilen 74, 80 angeordnete Paar Reflexionslichtschranken 84, 88 entfällt. Das erste Spiegelrandsignal wird beim Durchlaufen der Helldunkelgrenze bei Erreichen eines vorgewählten Ansprechpegels vom Spiegelrandsensor 86 bzw. 90 festgehalten und die Wegimpulsrate gezählt bis derselbe Ansprechpegel beim Durchlaufen der Dunkelhellgrenze am gegenüberliegenden Spiegelrand von demselben Sensor 86 bzw. 90 ermittelt wird.An alternative embodiment for the light barrier systems 1, 3 consists in that the phototransistor line 76 is omitted to determine the hole edge signals and the remaining phototransistor line 74 is aligned vertically with the light transmission line 80. If a given response level is reached at one edge of the hole, the path pulse rate of the disc belt or the slide is counted until the same response level is reached at the opposite edge of the hole. The center of the hole is determined by halving the path pulse rate. A corresponding procedure is advantageously used when determining the mirror center signal. The pair of reflection light barriers 84, 88 arranged behind the pair of phototransistor lines 74, 80 in the feed direction of the shooting disk 18 or the slide 38 is omitted. The first mirror edge signal is recorded by the mirror edge sensor 86 or 90 when the light-dark limit is passed when a preselected response level is reached, and the path pulse rate is counted until the same response level is passed when the dark light limit is passed the mirror edge is determined by the same sensor 86 or 90.

Wesentlich ist dabei, dass das erste Spiegelrandsignal jeweils gemeinsamer Zählstart für die Impulsraten zur Ermittlung der Differenz vom Spiegelmitten- und Lochmitten-Koordinaten ist. Deswegen muss der Spiegelrandsensor 86 bzw. 90 in Bewegungsrichtung der Scheibe bzw. des Schlittens 38 in einem Abstand vor dem Lochsensorzeilenpaar 74, 80 liegen. Dieser Abstand wird bei der Differenzbildung durch eine entsprechende konstante Wegimpulsrate berücksichtigt.It is essential that the first mirror edge signal is a common start of counting for the pulse rates for determining the difference between the mirror center and hole center coordinates. For this reason, the mirror edge sensor 86 or 90 must lie at a distance in front of the pair of hole sensors 74, 80 in the direction of movement of the disk or the slide 38. This distance is taken into account when forming the difference by means of a corresponding constant path pulse rate.
