Definitions
- the present invention relates to a method for detecting hits according to the preamble of claim 1. Furthermore, it relates to devices for carrying out the method.
- the laser light data is modulated.
- the modulation takes place by changes in intensity, in the simplest case by switching the light on and off.
- the transmitted data thus occur as light pulses.
- laser light Another aspect of using laser light is the safety of the participants.
- the laser sources must comply with the highest safety standards, so that a direct view into the laser source with the naked eye or even through binoculars can not cause any damage to the eye.
- the energy distribution of the laser beam is utilized.
- the laser light sources commonly used have a bell-shaped distribution of the intensity over the cross section with the maximum in the center of the light beam.
- the sensors measure the intensity of the light beam from which they are hit.
- a narrow error (passing by) or a "hit" outside the range of the weapon is characterized by an intensity below a predetermined threshold. Hits with a light intensity above this threshold are detected as hits.
- a disadvantage of this method is that the sensors used must have an increased sensitivity in order to be able to detect even with the necessary certainty the lower intensity of a brief error up to a minimum intensity.
- the intensity of the laser transmitter can not be arbitrarily increased because the safety requirements set an upper limit.
- the laser beam is pivoted by the weapon, depending on the angle to the firing direction other data are modulated.
- the receiver can thus derive from the data at what angle to the trajectory it is located and derive therefrom, whether a hit or a narrow error exists.
- a disadvantage of this solution is the increased effort in the laser source for the pivoting of the laser light and the dependent encoding of various data, the higher evaluation effort on the part of the receiver and the high cost, since in particular a complete swing cycle must wait for all positions until it is established that no hit at all is present.
- the GB-A-2 290 483 provides additional data shares to detect small errors. These additional pieces of data are sent at a lower intensity. If these weaker parts are also detected in addition to the data sent with "normal" intensity, this is a hit. If, on the other hand, only the data without the weaker components is detected, this is a close error. A disadvantage of this solution is the considerably increased amount of data, which leads to a higher expenditure of time for the distinction between a small error and a hit.
- Another object of the present invention is the simplified detection of a short error.
- Another object of the invention is to reduce the total energy of an energy beam used for shot simulation.
- data for identification of the weapon is transmitted by pulses or intensity modulation of the laser.
- part of the data is sent with significantly increased intensity or increased modulation deviation. For example, this is accomplished simply by increasing the power of the laser during the transmission of these data parts.
- the higher intensity transmitted data pieces comprise only a minor portion of the total transmitted data, so that the upper limit of the total intensity given for safety reasons, For example, the laser class I, can be achieved by only a small reduction in the intensity of the remaining data.
- the diagram 1 of Fig. 1 is a plot of time 3 (t) versus intensity 5 (I).
- a pulse 14 consists of a light pulse of a certain duration.
- the pulses 17, 18 are transmitted at a substantially higher intensity I 2 than the intensity I 1 of the "normal" pulses 14.
- the intensity I 2 must, according to experience, be at least twice the intensity I 1, are preferred Values of at least three times to four times I 1 with I 0 as the zero point, in the simplest case corresponding to the intensity 0.
- the pulses 17, 18 can also serve to secure the transmission, since they also detect with greater certainty because of their much higher intensity become.
- a target 25 eg, a simulation participant or an object such as a vehicle
- the target 25 is hit by the laser beam of a weapon.
- the laser beam has a core zone 31 in which the intensity of the normal data pulses 14 is above the detection threshold.
- the intensity of the data pulses lies below the detection threshold, but the intensity I 2 of the bypass pulses 17, 18 above.
- Fig. 2 represents a target 25 which is provided with sensors 27.
- the sensors 27 are set to emit a signal when hit by a simulated shot, ie the laser pulse emitted by the exerciser.
- Fig. 3 represents the situation of a hit: One of the sensors 27, the sensor 35, lies in the area of the core zone 31 and can therefore receive the date 9. A number of others Detectors 37 are located in the region of the edge zone 33, but not the core zone 31. The detection of the complete date by the sensor 35 takes precedence over the signal of the sensors 37 and leads to the detection of a hit. The situation is different in the Fig. 4 In this case, none of the sensors 27 are hit by the core zone 31, only two sensors 37 are located in the area of the flyby zone 33 of the laser beam 29. The sensors 37 thus detect the presence of a gun laser beam, but none of the detectors can completely decode a datum 9. However, the higher intensity data portions (pulses 17, 18) may be decoded. As a result, the target 25 was shot past.
- the different time intervals t 1 - t 0 bwz. t 2 -t 0 can be used to get an indication of the transmitters of the respective data 9. It is also conceivable to send the pulse 17 at other times within the date 9. Since it is preferably used for the purpose of transmission synchronization or the like, it is preferably sent at the beginning of the date 9.
- Fig. 5 shows the block diagram of a light beam transmitter.
- the controller 45 receives, for example when triggering a shot a signal 47 and then generates the control signals 49, which drive the light emitter 51.
- the light transmitter 51 sends out, under control of the control signals 49, the light beam 29 onto which the date 9 is modulated.
- the diagram 53 schematically represents the distribution of the intensity I over the radius r of the light beam 29.
- the curve 55 is the intensity of the data pulses 14, the curve 57 that of the pulses 17, 18 and 42 for a close pass-by.
- the line 59 is the intensity detection threshold I c of the detectors 27. The points of intersection of the detection threshold 59 with the curves 55 and 57 result in the zones 31 (hit area) and 33 (near by-shot).
- Fig. 5 schematically shows a hit detection device 63.
- a number of detectors 27, which are located at a target 25, are connected to an evaluation unit 65. If one of the detectors 27 delivers a hit signal, that is to say a complete datum 9, the evaluation unit 65 detects a direct hit and triggers the corresponding actions. On the other hand, if the evaluation unit 65 receives from at least one of the detectors 27 a signal for the detection of flyby pulses 17, 18 or 42, but none of the detectors 27 displays a signal which represents a complete datum 9, it recognizes a near pass by.

Abstract
Für die Simulation von Schusswaffen wird ein Laserstrahl (29) anstatt eines Schusses eingesetzt. Für die Erkennung eines nahen Vorbeischusses wird ein Hochintensitätsteil (17, 18; 42) des Datums (9), das dem Laserstrahl aufgeprägt ist, mit erhöhter Intensität (I 2 ) ausgesendet. Wegen der glockenkurvenförmigen Intensitätsverteilung ist dieser Teil erhöhter Intensität noch in grösserem Abstand von der Strahlmitte von Sensoren (27) detektierbar. Da der Hochintensitätsteil (17, 18; 42) einen integralen Bestandteil der Daten (9) darstellt und damit keine eigene Zeit für die Übertragung benötigt, wird die Erkennung eines nahen Vorbeischusses in der gleichen Zeitspanne wie die Erkennung eines Treffers möglich. Durch die Ausnutzung der glockenkurvenförmigen Intensitätsverteilung erfolgt die Erkennung durch Sensoren (27) mit der gleichen Intensitätsschwelle (I c ) wie für das Erkennen eines vollständigen Datums (9) im Falle eines Treffers.For the simulation of firearms a laser beam (29) is used instead of a shot. For detecting a near by-pass, a high-intensity part (17, 18, 42) of the datum (9) impressed on the laser beam is emitted with increased intensity (I 2). Because of the bell-shaped intensity distribution, this part of increased intensity can still be detected at a greater distance from the beam center of sensors (27). Since the high-intensity part (17, 18, 42) is an integral part of the data (9) and therefore does not need its own time for the transmission, the detection of a near by-pass in the same time as the detection of a hit is possible. By taking advantage of the bell-shaped intensity distribution, the detection by sensors (27) with the same intensity threshold (I c) as for the detection of a complete date (9) in the case of a hit.
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Erkennung von Treffern gemäss Oberbegriff des Patentanspruchs 1. Des Weiteren betrifft sie Vorrichtungen zur Durchführung des Verfahrens.The present invention relates to a method for detecting hits according to the preamble of
Für Gefechtsübungen ist es bekannt, Waffen zu verwenden, bei denen Schüsse durch Laserlichtstrahlen simuliert werden. Die Teilnehmer an den Übungen, aber auch mögliche Zielobjekte sind mit Sensoren bestückt, die beim Auftreffen eines Laserstrahls, d.h. eines simulierten Schusses, ein Signal abgeben. Das Auftreten eines solchen Signales wird für die Anzeige eines Treffers verwendet. Die Auswertung kann auf verschiedene Arten erfolgen, z.B. durch zentrale Registrierung, wobei das Signal z.B. per Funk übertragen wird, lokale Signaturen (Feuererscheinungen, usw.), akustische Signale usw.For combat exercises, it is known to use weapons in which shots are simulated by laser light beams. The participants in the exercises, but also possible target objects are equipped with sensors which, when a laser beam strikes, i. a simulated shot, give a signal. The occurrence of such a signal is used for the display of a hit. The evaluation can be done in several ways, e.g. by central registration, the signal e.g. transmitted by radio, local signatures (fire phenomena, etc.), acoustic signals, etc.
Dem Laserlicht sind Daten aufmoduliert. Die Modulation erfolgt dabei durch Änderungen der Intensität, im einfachsten Fall durch Ein- und Ausschalten des Lichts. Die übertragenen Daten treten damit als Lichtpulse auf.The laser light data is modulated. The modulation takes place by changes in intensity, in the simplest case by switching the light on and off. The transmitted data thus occur as light pulses.
Ein anderer Aspekt bei der Verwendung von Laserlicht ist die Sicherheit der Teilnehmer. Generell müssen die Laserquellen der höchsten Sicherheitsklasse entsprechen, sodass auch ein direkter Blick in die Laserquelle mit nacktem Auge oder sogar durch ein Fernglas keine Schäden am Auge hervorrufen kann.Another aspect of using laser light is the safety of the participants. In general, the laser sources must comply with the highest safety standards, so that a direct view into the laser source with the naked eye or even through binoculars can not cause any damage to the eye.
Es hat sich gezeigt, dass die Erkennung ausschliesslich von Treffern einen wesentlichen Mangel an Realitätsnähe aufweist. Es ist daher wünschenswert, auch knappe Fehlschüsse zu erkennen. Ein solcher knapper Fehlschuss kann durch optische oder akustische Signale angedeutet werden und z.B. die Aufmerksamkeit darauf lenken, dass ein Beschuss stattfindet.It has been shown that the recognition of hits only has a substantial lack of realism. It is therefore desirable to detect even brief misses. Such a short miss can be indicated by optical or acoustic signals and, for example, draw attention to the fact that a bombardment takes place.

Ausgehend insbesondere von der letzt genannten Schrift ist es eine Aufgabe der vorliegenden Erfindung, ein Verfahren anzugeben, das eine schnellere Erkennung eines knappen Fehlers bzw. eines Treffers gestattet.Starting from the last-mentioned document in particular, it is an object of the present invention to specify a method which allows a quicker detection of a short error or a hit.
Eine weitere Aufgabe der vorliegenden Erfindung ist die vereinfachte Erkennung eines knappen Fehlers.Another object of the present invention is the simplified detection of a short error.
Eine weitere Aufgabe der Erfindung besteht darin, die Gesamtenergie eines für die Schussimulation verwendeten Energiestrahls zu verringern.Another object of the invention is to reduce the total energy of an energy beam used for shot simulation.
Ein Verfahren, das wenigstens die erstgenannte Aufgabe löst, ist im Patentanspruch 1 angegeben. Die weiteren Patentansprüche geben bevorzugte Ausführungsformen sowie Vorrichtungen zur Durchführung des Verfahrens an.A method which at least solves the first object is given in
Demgemäss werden wie üblich Daten zur Identifikation der Waffe durch Pulse oder Intensitätsmodulation des Lasers übertragen. Zusätzlich wird ein Teil der Daten mit deutlich erhöhter Intensität bzw. erhöhtem Modulationshub gesendet. Beispielsweise wird dies einfach durch Erhöhung der Leistung des Lasers während des Sendens dieser Datenteile bewirkt.Accordingly, as usual, data for identification of the weapon is transmitted by pulses or intensity modulation of the laser. In addition, part of the data is sent with significantly increased intensity or increased modulation deviation. For example, this is accomplished simply by increasing the power of the laser during the transmission of these data parts.
Durch die Erhöhung der Intensität dieser Datenteile sind sie noch in grösserem Abstand vom Zentrum des Laserstrahls detektierbar, d.h. ein Sensor mit vorgegebener Erkennungsschwelle kann sie noch in grösserem Abstand vom Zentrum erkennen. Dieser besondere Datenteil stellt auch einen integralen Bestandteil der normalerweise übertragenen Daten dar, sodass für ihre Übertragung keine zusätzliche Zeit erforderlich ist. Bevorzugt umfassen die mit höherer Intensität übertragenen Datenteile nur einen untergeordneten Anteil der insgesamt gesendeten Daten, sodass die aus Sicherheitsgründen gegebene Obergrenze der Gesamtintensität, z.B. die Laserklasse I, durch eine nur geringe Absenkung der Intensität der übrigen Daten erzielt werden kann.By increasing the intensity of these data parts they are still detectable at a greater distance from the center of the laser beam, ie a sensor with a predetermined detection threshold can still detect it at a greater distance from the center. This particular piece of data is also an integral part of the data that is normally transmitted, so there is no extra time to transfer it. Preferably, the higher intensity transmitted data pieces comprise only a minor portion of the total transmitted data, so that the upper limit of the total intensity given for safety reasons, For example, the laser class I, can be achieved by only a small reduction in the intensity of the remaining data.

Ein Puls 14 besteht aus einem Lichtpuls bestimmter Dauer. Die Pulse 17, 18 werden mit einer wesentlich höheren Intensität I2 als die Intensität I1 der "normalen" Pulse 14 gesendet. Die Intensität I2 muss erfahrungsgemäss mindestens das Doppelte der Intensität I1 betragen, bevorzugt sind Werte von mindestens dem Dreifachen bis dem Vierfachen von I1 mit I0 als Nullpunkt, im einfachsten Fall entsprechend der Intensität 0. Die Pulse 17, 18 können daneben der Sicherung der Übertragung dienen, da sie wegen ihrer wesentlich höheren Intensität auch mit grösserer Sicherheit detektiert werden.A
Offensichtlich wird für die zusätzliche Erkennung eines knappen Fehlers hier keinerlei zusätzliche Zeit benötigt, da die Pulse 17, 18 ein integraler Bestandteil des Datenpakets 9 sind. Ausserdem werden nur Detektoren einer bestimmten Empfindlichkeit und eine Auswertung mit genau einer Detektionsschwelle benötigt, da sich der grössere Radius für die Erkennung eines knappen Fehlers aus der Verbindung zwischen der höheren Intensität I2 und der glockenkurvenförmigen Intensitätsverteilung im Lichtstrahl 29 ergibt. Diese Situation wird in den Figg. 2 und 3 grafisch dargestellt. Ein Ziel 25 (z.B. ein Simulationsteilnehmer oder ein Objekt wie ein Fahrzeug), ist mit Sensoren 27 bestückt. Das Ziel 25 wird vom Laserstrahl einer Waffe getroffen. Der Laserstrahl weist eine Kernzone 31 auf, in der die Intensität der normalen Datenpulse 14 oberhalb der Detektionsschwelle liegt. In der umgebenden Zone 33 liegt dagegen die Intensität der Datenpulse unterhalb der Detektionsschwelle, aber die Intensität I2 der Vorbeischusspulse 17, 18 oberhalb.Obviously, no additional time is needed here for the additional detection of a short error, since the
Aus der vorangehenden Darstellung, namentlich
Ausgehend von der vorangehenden Beschreibung der Erfindung und eines bevorzugten Ausführungsbeispieles sind dem Fachmann zahlreiche Abwandlungen zugänglich, ohne den Schutzbereich der Erfindung zu verlassen, der durch die Patentansprüche gegeben ist. Denkbar sind namentlich:
- Es sind mehr als zwei
17, 18 mit erhöhter Intensität vorhanden, z.B. drei oder vier. Entsprechend steigen damit auch die Möglichkeiten bzw. die Genauigkeit, mit der der Sender selbst bei einem nahen Vorbeischuss identifiziert werden kann, und/oder die Sicherheit der Treffererkennung. Denkbar ist auch nur ein derartigerPulse Puls 17, wodurch eine Identifikation des Senders ausscheidet. 17, 18 für die Erkennung eines nahen Fehlschusses mit verschiedener, jedoch deutlich unterschiedlicher Intensität vorhanden. Damit ergibt sich mehrEs sind Pulse als ein Vorbeischussbereich 33 um dieKernzone 31, wodurch in Stufen die Entfernung eines Vorbeischusses bestimmbar ist.- Die Modulation muss nicht 100 % sein, d.h. zwischen den Pulsen, innerhalb der Pulse und/oder zwischen den Datenpaketen kann der Lichtsender einen schwachen Lichtstrahl aussenden. Entscheidend ist die Differenz zwischen dieser Grundhelligkeit I0 und der Spitzenintensität I1 der
Pulse 14 bzw. I2 der 17, 18 bzw. 42.Pulse
- There are more than two
17, 18 of increased intensity, eg three or four. Correspondingly, the possibilities or the accuracy with which the transmitter can be identified even in the case of a close by-pass, and / or the security of the detection of hits, accordingly increase. Also conceivable is only such apulses pulse 17, which eliminates an identification of the transmitter. - There are
17, 18 for the detection of a close miss with different, but significantly different intensity. This results in more than one Vorbeischussbereich 33 to thepulses core zone 31, which in stages the removal of a Vorbeischusses can be determined. - The modulation need not be 100%, ie between the pulses, within the pulses and / or between the data packets, the light emitter may emit a weak beam of light. Decisive is the difference between this basic brightness I 0 and the peak intensity I 1 of the
pulses 14 or I 2 of the 17, 18 and 42, respectively.pulses
