Description

Die Erfindung betrifft eine Vorrichtung zur Erkennung bzw. Identifizierung einer Munition insbesondere bei der Zuführung unterschiedlicher Munitionstypen zu einer Waffe.The invention relates to a device for detecting or identifying an ammunition, in particular when supplying different types of ammunition to a weapon.

Zweck derartiger Erkennungen und Identifizierungen sind das Auslesen von Munitionsdaten beispielsweise für die Berechnung von Aufsatz- und Vorhaltewinkel, die verwechslungsfreie Zuführung des jeweils ausgewählten Munitionstyps sowie die Weiterleitung dieser Daten an das Waffensystem und einen Feuerleitrechner.Purpose of such detections and identifications are the reading of ammunition data, for example, for the calculation of essay and angle, the unerring supply of each selected type of ammunition and the forwarding of these data to the weapon system and a Feuerleitrechner.

Bekanntlich werden Maschinenkanonen, die mit einer hohen Kadenz arbeiten, durch einen Munitionsbehälter mit unterschiedlichen Munitionstypen versorgt. Diese werden für verschiedene Zielbekämpfungen benötigt. Je nach Vorgabe eines Bedieners wird dann für die jeweilige Aufgabe die entsprechende Munition verschossen. Unterschiedliche Munitionstypen können dabei Luft-Luft Kampfmunition, Luft-Boden Kampfmunition und / oder Übungsmunition sein. Auch Exerziermunition oder Impulskartuschen sowie nichtletale Munitionen sind möglich. In der Regel handelt es sich bei dieser Munitionszuführung um ein in sich geschlossenes, umlaufendes Munitionstransportsystem, bei dem in einer Zuführposition die Munition über einen Zuführstern einer Trommel der Waffe übergeben wird.As is known, high-cadence machine guns are supplied with ammunition containers of different types of ammunition. These are needed for different targeting. Depending on the specification of an operator then the corresponding ammunition is fired for each task. Different types of ammunition can be air-to-air combat ammunition, air-to-ground combat ammunition and / or training ammunition. Training ammunition or pulse cartridges as well as non-lethal ammunitions are also possible. As a rule, this ammunition feed is a self-contained circulating ammunition transport system in which, in a feed position, the ammunition is transferred via a feed star to a drum of the weapon.

Aus der DE 41 37 819 A1 ist eine Vorrichtung zum Identifizieren von Munition bekannt, die eine Datenverarbeitungsanlage mit einer Lese- und / oder Schreibeinrichtung umfasst. An der Munition ist ein Datenträger angeordnet, der mit der Datenverarbeitungsanlage kommuniziert. Die Datenträger können als ROM und / oder RAM Speicher, Transponder oder als Bar- oder Farbcodes ausgebildet und auf der Oberfläche der Munition oder in dieser integriert sein.From the DE 41 37 819 A1 a device for identifying ammunition is known which comprises a data processing system with a reading and / or writing device. At the ammunition a disk is arranged, which communicates with the data processing system. The data carriers can be designed as ROM and / or RAM memory, transponder or as bar or color codes and be integrated on the surface of the ammunition or in this.

In der DE 38 30 903 C2 sind ein Verfahren zur Erkennung von unterschiedlichen Munitionstypen sowie eine Munition offenbart. Da für einen Waffentyp unterschiedliche Munitionsarten von unterschiedlichen Herstellern bestehen und dementsprechend bei Abschuss der Munition auch unterschiedliche Schiessergebnisse zu erwarten sind, wird vorgeschlagen, ein Erkennungssystem, beispielsweise eine optische, elektronische oder mechanische Sensorik, in das Waffensystem einzubinden. In einer bevorzugten Variante wird die Waffe entsprechend der zugeführten Munition mittels einer Stelleinrichtung selbsttätig auf entsprechende Einstellwerte eingestellt. Auch hier werden Aussagen, wo das Erkennungssystem integriert ist, nicht gemacht.In the DE 38 30 903 C2 a method for detecting different types of ammunition and ammunition are disclosed. Since different kinds of ammunition from different manufacturers exist for a weapon type and accordingly different firing results are to be expected when the ammunition is launched, it is proposed to use a detection system, For example, an optical, electronic or mechanical sensors to integrate into the weapon system. In a preferred variant, the weapon is automatically adjusted to corresponding setting values by means of an adjusting device in accordance with the supplied ammunition. Again, statements where the recognition system is integrated are not made.

Die EP 0 467 754 A1 beschäftigt sich mit einer Steuervorrichtung zum automatischen Laden eines Geschützes eines Panzerfahrzeugturms, die so genannte Auswahlmittel für die Beschaffenheit der zu verwendeten Munition aufweist und elektronische Mittel zur Verwaltung der Munition besitzt. Die Auswahlmittel ermöglichen dabei das Magazin zu lesen und neu zu konfigurieren. Mittel zum Erkennen des Munitionstyps sind an jedem Magazinplatz angeordnet.The EP 0 467 754 A1 deals with a control device for automatically loading a gun of an armored vehicle tower, which has so-called selection means for the nature of the ammunition to be used and has electronic means for managing the ammunition. The selection means allow the magazine to be read and reconfigured. Means for recognizing the ammunition type are arranged at each magazine location.

Mit der DE 10 2004 025 742 A1 wird eine Einrichtung zur Zuführung von Treibladungen zu einer schweren Waffe publiziert, die an jedem Aufnahmeelement einer Treibladungskette Sensorelemente zur Feststellung der Modulart und des Füllgrades angeordnet sind. Die Sensorelemente weisen um den Umfang der Schalen geführte Federstreifen mit einem durch eine Öffnung der Schale ragende Abtastelemente auf. Jedem Federstreifen ist an seiner Außenseite ein Näherungssensor oder -schalter gegenüberliegend zugeordnet.With the DE 10 2004 025 742 A1 a device for supplying propellant charges to a heavy weapon is published, which are arranged on each receiving element of a propellant charge chain sensor elements for determining the type of module and the degree of filling. The sensor elements have spring strips guided around the circumference of the shells with a scanning element projecting through an opening of the shell. Each spring strip is associated with a proximity sensor or switch on its outside opposite.

Diese Problematik der Einbindung eines Erkennungssystems in ein Waffensystem ist Gegenstand der Erfindung, die sich die Aufgabe stellt, eine Vorrichtung zur Munitionstyperkennung anzugeben, die auch unter extremen Bedingungen, wie Schmutz und hohe Temperaturen, funktionsfähig ist.This problem of the integration of a detection system in a weapon system is the subject of the invention, which has as its object to provide a device for Munitionstyperkennung that is functional even under extreme conditions, such as dirt and high temperatures.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1, 2 oder 3. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen enthalten.The object is achieved by the features of claim 1, 2 or 3. Advantageous embodiments are contained in the subclaims.

Der Erfindung liegt die Idee zugrunde, eine Erkennungseinrichtung im Bereich der Munitionsübergabe an die Waffe einzubinden. Dies sollte in der Regel ein umlaufendes Zuführsystem voraussetzen. Die Zuführung kann beispielsweise über eine Becherkette erfolgen, welche die Munition aufnimmt, oder wie es bei Waffenanlagen mit hoher Kadenz bekannt ist, durch ein Munitions- Transport- System (MTS). Diese Erkennungseinrichtung hat die Aufgabe, die für eine Zielbekämpfung benötigte Munition zu erkennen und in Weiterführung der Erfindung deren Position in der Becherkette oder dem MTS zu bestimmen. Daher muss die Erkennungseinrichtung zur Munition derart ausgerichtet sein, dass diese die Information auslesen kann, was vorzugsweise in der Zuführ- bzw. Munitionsübergabeposition erfolgt.The invention is based on the idea to incorporate a detection device in the area of ammunition transfer to the weapon. This should normally require a circulating feeding system. The supply can be done for example via a chain of crockery, which receives the ammunition, or as it is known in weapons systems with high cadence, through an ammunition transport system (MTS). This detection device has the task of recognizing the ammunition required for a target control and to determine its position in the bucket chain or the MTS in continuation of the invention. Therefore, the detection device must be aligned with the ammunition so that it can read the information, which preferably takes place in the supply or ammunition transfer position.

Um evtl. starken Erschütterung entgegenzuwirken, werden die gesamten elektronischen und optischen Bauteile der Erkennungshardware in einer Hartplastikschale eingebunden. Für den Einsatz bei extremen Temperaturen wird die Erkennungshardware zusätzlich mit einer zweiten Hartplastikschale umgossen. Um die komplette Erkennungshardware luftdicht und kratzfest einzuschließen, wird an die zweite Schale eine 2 bis 3 mm dicke Glasscheibe mit Dichtungen angebracht. Die Luft zwischen erster und zweiter Hartplastikschale dient als Isolator, zumal Luft ein schlechter Wärmeleiter ist. Zudem wird damit gewährleistet, dass die Erkennungshardware gegen Schmutz und Feuchtigkeit geschützt ist. Die Glasscheibe sollte dagegen immer sauber gehalten werden, da ansonsten kein störungsfreier Lesebetrieb gewährleistet werden kann. Dabei muss besonders darauf geachtet werden, dass die Putzelemente nicht zu hart sind, da die Glasscheibe sonst verkratzt wird und dadurch der Lesebetrieb gestört werden kann.To counteract possibly strong vibration, the entire electronic and optical components of the detection hardware are integrated in a hard plastic shell. For use in extreme temperatures, the detection hardware is additionally encapsulated with a second hard plastic shell. To seal the entire detection hardware air-tight and scratch-resistant, a 2 to 3 mm thick glass pane with seals is attached to the second shell. The air between the first and second hard plastic shell serves as an insulator, especially as air is a poor conductor of heat. It also ensures that the detection hardware is protected against dirt and moisture. On the other hand, the glass pane should always be kept clean, otherwise no trouble-free reading operation can be guaranteed. Care must be taken to ensure that the cleaning elements are not too hard, otherwise the glass pane will be scratched, which may disturb the reading operation.

Bei der Nutzung eines MTS beispielsweise bei einer Tommelwaffe, besteht eine Möglichkeit darin, die Erkennungseinrichtung zum Zuführstern des MTS auszurichten.When using an MTS, for example, in a Tommelwaffen, there is a possibility to align the detection device to the feed star of the MTS.

Als bevorzugte Position der Erkennungs-Hardware ist in Weiterführung der Erfindung der Innenraum des Zuführsterns des MTS vorgesehen. Die Konstruktion des Sterns wird dazu so ausgelegt, dass der Innenraum hohl ist und trotzdem eine ausreichende Festigkeit vorliegt. Für die Nutzung der Hardware im Innenraum sind Aussparungen im Stern konstruiert, um die Informationen auf den Patronen bzw. Munition zu detektieren. Die Aussparungen des Sterns ergeben sich aus der verwendeten Erkennungshardware und können angepasst werden.As a preferred position of the detection hardware is provided in a continuation of the invention, the interior of the feed star of the MTS. The design of the star is designed so that the interior is hollow and yet there is sufficient strength. For the use of the hardware in the interior recesses are designed in the star to detect the information on the cartridges or ammunition. The recesses of the star arise from the used detection hardware and can be adapted.

Der Zugang von einer Seite zum Innenraum des Zuführsterns von außen ist bei der Konstruktion der Lagerungen, Zahnräder und dem Gehäuse des MTS berücksichtigt. Das Gehäuse hat vorzugsweise eine rechteckige Aussparung, um somit die Anbringung von Halterungen und die Stormversorgung von außen für eine evtl. Elektronik im Inneren des Zuführsterns zu realisieren.The access from one side to the interior of the feed star from the outside is taken into account in the construction of the bearings, gears and the housing of the MTS. The housing preferably has a rectangular recess, so as to realize the attachment of brackets and the power supply from the outside for any electronics inside the feed star.

Als Erkennungshardware können mechanische, elektronische sowie optische Systeme dienen. Bevorzugt wird jedoch ein Barcodesystem verwendet. Ein Barcode enthält Informationen, die nach einer bestimmten Vorschrift verschlüsselt werden. Er stellt dieses Datenmaterial innerhalb des Barcodefeldes in Form von vertikalen Strichen unterschiedlicher Breite und Zwischenräumen (Lücken) graphisch dar. Neben linearen Barcodes mit gängigen Laserscannern oder linearen CCD - Detektoren sind auch gestapelte und Matrix- Codes verwendbar. Um alle Informationsschichten des Stapels zu erfassen, sind zweidimensionale Lesesysteme - also Kameras oder 2D- Detektoren, verwendbar. In der bevorzugten Ausführung wird ein eindimensionaler Barcode genutzt, da dieser von allen Seiten und zu jeder Winkelstellung lesbar ist, sowie ein herkömmlicher Barcodelaser eingesetzt.The detection hardware can be mechanical, electronic and optical systems. Preferably, however, a bar code system is used. A barcode contains information that is encrypted according to a specific rule. It graphically displays this data within the barcode field in the form of vertical bars of different widths and gaps (gaps). In addition to linear barcodes with common laser scanners or linear CCD detectors, stacked and matrix codes can also be used. In order to capture all information layers of the stack, two-dimensional reading systems - ie cameras or 2D detectors - can be used. In the preferred embodiment, a one-dimensional barcode is used because it is readable from all sides and at any angular position, as well as a conventional barcode laser.

Der Informationsträger befindet sich in der bevorzugten Variante der Barcode, radial auf /um der Munition. Um den Informationsträger vor Beschädigungen durch Antriebs- und Führungselemente des MTS zu schützen, wird die Anordnung des Trägers in der Mitte der Munition favorisiert.The information carrier is located in the preferred variant of the bar code, radially on / around the ammunition. In order to protect the information carrier from damage by drive and guide elements of the MTS, the arrangement of the carrier in the middle of the ammunition is favored.

Neben dem Munitionstyp, damit das System den geeigneten Geschosstyp wählen kann, sollten die Losnummer, wegen evtl. Schwankungen der relevanten Kerngrößen (Druck, Geschwindigkeit, Temperatur), die Geschwindigkeit v0 und wenn nicht in der Losnummer enthalten, das Herstelldatum und der Hersteller auf dem Informationsträger (Code) vermerkt sein. Die Geschwindigkeit v0 ist für die genaue Berechnung der Abschusswinkel (Azimut und Elevation) von Bedeutung. Die Anfangsgeschwindigkeit im Barcode dient beispielsweise als Referenzgeschwindigkeit zu der in der Losnummer hinterlegten Geschwindigkeit. Abweichungen sind dann wichtig für die Berechnung der Abschusswinkel. Das Herstelldatum dient beispielsweise dazu, die bisherige Lagerzeit der Munition berücksichtigen zu können.In addition to the type of ammunition, so that the system can choose the appropriate bullet type, the lot number, due to possible fluctuations of the relevant core sizes (pressure, speed, temperature), the speed v 0 and if not included in the lot number, the date of manufacture and the manufacturer on the information carrier (code) noted be. The velocity v 0 is important for the exact calculation of the launch angles (azimuth and elevation). The initial velocity in the barcode serves, for example, as a reference velocity to the speed stored in the lot number. Deviations are then important for the calculation of the launch angles. The date of manufacture serves, for example, to be able to take into account the previous storage time of the ammunition.

Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Wenngleich sich die nachfolgenden Ausführungen auf die Zuführung für eine Trommelwaffe beziehen, ist die Anwendung auch auf Waffensysteme mit einer andersartigen, insbesondere umlaufenden Munitionszuführung, wie beispielsweise mittels einer Becherkette, welche die Munition trägt, und Schwingen oder dergleichen, die die Munition von dieser Zuführung an die Waffe geben, anwendbar.Reference to an embodiment with drawing, the invention will be explained in more detail. Although the following statements refer to the supply for a drum weapon, the application is also on weapon systems with a different, in particular circulating ammunition supply, such as by means of a cup chain carrying the ammunition, and swinging or the like, the ammunition from this feeder give the weapon, applicable.

In der bevorzugten Ausführung nach Fig. 3 ist das Erkennungssystem 4 im Zuführstern 3 integriert. Durch Schlitzöffnungen 3.1 im Zuführstern 3 (Fig. 4) können die Daten der jeweiligen Munition 2 ausgelesen werden. Der Zuführstern 3 rotiert dabei um das feststehende Erkennungssystem 4, welches innerhalb einer hohlen Baueinheit 16 im Zuführstern 3 gelagert ist (Fig.5).In the preferred embodiment according to Fig. 3 the detection system 4 is integrated in the feed star 3. Through slot openings 3.1 in the feed star 3 ( Fig. 4 ), the data of the respective ammunition 2 can be read out. The feed star 3 rotates about the fixed detection system 4, which is mounted within a hollow unit 16 in the feed star 3 ( Figure 5 ).

Als Erkennungssystem 4 wird ein Barcodescanner befürwortet, der mittig im Zuführstern 3 positioniert ist. Die Aussparungen bzw. Schlitzöffnungen 3.1 sind den optimalen Lesebedingungen des Laserstrahls 15 angepasst. Bewährt hat sich ein Öffnungswinkel der Aussparungen 3.1 von 30° bis 35°.

Fig. 4 shows in a slightly enlarged view the feed star 3 with the recognition system 4. This is on the lying in the feed star 3 ammunition 2 (preferably in the transfer position to the drum 20) aligned. The beam 15 passes through the slot opening 3.1.

Fig. 5 zeigt die Lagerung des Erkennungssystems 4 im Zuführstern 3 sowie das Zusammenspiel der Information (Barcode) 18 auf der Munition 2 mit dem Erkennungssystem 4. Fig. 5 shows the storage of the recognition system 4 in the feed star 3 and the interaction of the information (bar code) 18 on the ammunition 2 with the recognition system. 4

Fig. 6 gibt das Prinzip der Abtastung der Information 18 von der Munition 2 an. Mit Hilfe des Laserstrahls 15 wird die Information ausgelesen und zur Weiterverarbeitung beispielsweise an einen waffenseitigen Rechner (nicht näher dargestellt) gegeben. Fig. 6 gives the principle of scanning the information 18 from the ammunition 2. With the help of the laser beam 15, the information is read and given for further processing, for example, to a weapon-side computer (not shown in detail).

Im Falle einer Rückführung der leeren Hülsen oder nicht verschossener Munition in das MTS 1, wenn es sich bei der Munition also nicht um hülsenlose Geschosse handelt, wird softwaremäßig sichergestellt, dass dies im waffenseitigen Rechner bei der weiteren Munitionszuführung berücksichtigt wird.In the case of a return of the empty pods or unmashed ammunition into the MTS 1, if the ammunition is therefore not caseless projectiles, it is ensured by software that this is taken into account in the weapon-side computer in the further ammunition supply.
