Description

Die Erfindung betrifft eine Vorrichtung zur Überwachung der Initiierung eines Wirksystems , umfassend wenigstens einen Sensor im Bereich der Sprengladung und/oder im Bereich wenigstens einer Zündeinrichtung für die Sprengladung des Wirksystems, sowie eine Steuerungseinrichtung zur Auswertung der Sensor-Ausgangssignale welche mit wenigstens einer Zündeinrichtung nach Maßgabe der Auswertung steuernd verbunden ist.The invention relates to a device for monitoring the initiation of an active system, comprising at least one sensor in the field of explosive charge and / or at least one ignition device for the explosive charge of the active system, and a control device for evaluating the sensor output signals with at least one ignition device in accordance with controlling the evaluation is connected.

Für eine flexible Leistungssteuerung wurden bereits skalierbare Wirksystemkonzepte vorgeschlagen, deren kompaktes Zündsystem zwei Zündkreise und zwei pyrotechnische Ausgänge vereint, die mit einer Zeitsteuerung verknüpft werden können. Damit lassen sich verschiedene Wirkmodi realisieren, von der kontrollierten Deflagration als minimaler Wirkung über zeitlich versetzte, kombinierte Reaktionsmechanismen als Zwischenwirkungen bis hin zur klassischen Detonation mit der maximalen Wirkung. Durch diese räumliche Kombination von Deflagrator und Detonator in einem kompakten Zündsystem ergeben sich zahlreiche praktische und operative Vorteile.For flexible power control, scalable system concepts have already been proposed, whose compact ignition system combines two ignition circuits and two pyrotechnic outputs, which can be linked with a timer. Thus, different modes of action can be realized, from the controlled deflagration as a minimal effect to temporally offset, combined reaction mechanisms as intermediate effects to classic detonation with the maximum effect. This spatial combination of deflagrator and detonator in a compact ignition system provides numerous practical and operational benefits.

Es sind bereits Sensoren bekannt geworden, die den Verlauf einer Deflagrationsfront in der Sprengladung eines derartigen Wirksystems erfassen und auswerten können. Die DE 10 2012 006 044 B3 beschreibt ein derartiges Verfahren und eine dazu geeignete Vorrichtung, mit deren Hilfe nach der Initiierung einer Deflagration der Sprengladung auch der Zündzeitpunkt einer weiteren Zündkette ermittelt werden kann.
Aus der Anwendung eines solchen Wirksystems ergeben sich spezifische Anforderungen an das Zündsystem, um bei Anwahl eines subdetonativen Wirkmodus mit hoher Funktionszuverlässigkeit sicherzustellen, dass es zumindest zu keiner stärkeren Umsetzung der Sprengladung als der gewählten kommt. Dies ist zum Beispiel dann der Fall, wenn der Deflagratorzündkreis versagt oder aus anderen Gründen die Einleitung der Deflagrationsreaktion nicht erfolgt und der zeitlich versetzte Detonatorzündkreis die detonative Umsetzung der Sprengladung einleitet. Dies würde dann zur maximalen oder wenigstens einer höheren Leistung als beabsichtigt führen. Damit wären dann eigene Truppen in der Nähe gefährdet oder unbeabsichtigte Begleitschäden an Nichtkombattanten oder Gebäuden die Folge.
There are already known sensors that can detect and evaluate the course of a deflagration front in the explosive charge of such an active system. The DE 10 2012 006 044 B3 describes such a method and a device suitable for this, with the aid of which, after the initiation of a deflagration of the explosive charge, the ignition time of a further ignition chain can also be determined.
From the application of such an active system, there are specific requirements for the ignition system in order to ensure, when selecting a subdetonative mode of action with high functional reliability, that there is at least no greater implementation of the explosive charge than the one selected. This is the case, for example, if the deflagrator ignition circuit fails or for other reasons the initiation of the deflagration reaction does not take place and the time-shifted detonator ignition circuit initiates the detonative conversion of the explosive charge. This would then lead to the maximum or at least a higher performance than intended. This would endanger your own troops in the vicinity or unintentional accompanying damage to non-combatants or buildings.

Weniger kritisch sind dabei Fälle, bei denen der Detonatorzündkreis versagt, was zur minimalen Wirkung führt, oder wenn beide Zündkreise versagen. Während der erste Fall aus operativer Sicht akzeptabel sein dürfte, resultiert letzter Punkt in einem Versager mit einer nicht umgesetzten Sprengladung. Um die Eintrittswahrscheinlichkeit eines solchen Ereignisses gering zu halten, ist wie bisher durch das Zündsystemdesign und entsprechende Bauteilauswahl Rechnung zu tragen. Zudem wird dies in der Praxis gegenüber einer höheren Leistung als beabsichtigt grundsätzlich zu bevorzugen sein.Less critical are cases where the Detonatorzündkreis fails, resulting in the minimum effect, or if both ignition circuits fail. While the first case might be acceptable from an operational point of view, the final point is a failure with an unreacted explosive charge. In order to minimize the probability of occurrence of such an event, account must be taken of the ignition system design and the corresponding selection of components. moreover In practice, this will be preferable to higher performance than intended.

Die DE 10 2014 004 003 B3 beschreibt ein Zündsystem für ein hinsichtlich seiner Leistungsabgabe skalierbares Wirksystem mit zwei unterschiedlichen Zündkreisen für die subdetonative und die detonative Initiierung der Sprengladung des Wirksystems, wobei ein Kontrollmechanismus im subdatonativen Zündkreis die korrekte Funktion überwacht und damit die unkontrollierte vollständige Leistungsabgabe der Wirkladung verhindert.The DE 10 2014 004 003 B3 describes an ignition system for a power-scalable active system with two different ignition circuits for the subdetonative and detonative initiation of the explosive system of the active system, whereby a control mechanism in the subdatational ignition circuit monitors the correct function and thus prevents the uncontrolled full power output of the active charge.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, die Funktionssicherheit des Zündsystems gegenüber bisher Bekanntem mit Hilfe geeigneter Maßnahmen nach einer ausbleibenden subdetonativen Reaktion wie beispielsweise einer Deflagration zu erhöhen.The present invention is therefore based on the object to increase the reliability of the ignition system with respect to previously known with the aid of suitable measures for a lack of subdetonative reaction such as a deflagration.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, dass wenigstens ein Sensor am Ausgang einer ersten Zündeinrichtung für die subdetonative Initiierung der Sprengladung angeordnet ist, dass die Steuerungseinrichtung mit einer weiteren Zündeinrichtung verbunden ist und diese nach Maßgabe des vom Sensor gelieferten und in der Steuerungseinrichtung bewerteten Signals frei gibt oder sperrt, dass wenigstens ein Sensor für die Erfassung von Druck, Temperatur, Licht, elektrischer Strom oder Änderung mechanischer Zustände ausgelegt ist, und dass der Sensor das pyrotechnische Ereignis der deflagrativen Umsetzung der Sprengladung anhand geeigneter physikalischer Größen detektiert.This object is achieved according to the invention in that at least one sensor is arranged at the output of a first ignition device for the subdetonative initiation of the explosive charge, that the control device is connected to a further ignition device and this in accordance with the signal supplied by the sensor and evaluated in the control device free or blocks that at least one sensor for the detection of pressure, temperature, light, electric current or change of mechanical conditions is designed, and that the sensor detects the pyrotechnic event of deflagrativen implementation of the explosive charge by means of suitable physical quantities.

Ein Sensor, der das pyrotechnische Ereignis der deflagrativen Umsetzung der Sprengladung anhand geeigneter physikalischer Größen detektiert, kann zu einer weiteren Verbesserung der Zuverlässigkeit von Zündsystem und Wirkteil führen. Durch Verknüpfung des Sensors mit der Kontrolleinheit des Zündsystems, in der sich auf die Zeitsteuerungslogik für die Wirkmodi befindet, wird erst nach positiver Detektion des Deflagrationsereignisses der Detonator freigegeben und ausgelöst.A sensor which detects the pyrotechnic event of the deflagrative conversion of the explosive charge by means of suitable physical quantities can lead to a further improvement in the reliability of the ignition system and the active part. By linking the sensor with the control unit of the ignition system, which is on the timing logic for the modes of action, the detonator is released and triggered only after positive detection of the deflagration event.

Weitere Ausführungsformen der erfindungsgemäßen Vorrichtung sind in den weiteren abhängigen Ansprüchen beschrieben.Further embodiments of the device according to the invention are described in the further dependent claims.

Die Vorteile des Vorschlags bestehen darin, dass die Funktionszuverlässigkeit des Zündsystems sowohl schaltungstechnisch als auch durch geeignete Auswahl der elektrischen Bauteile und der One-Shot-Devices wie Detonatoren und EFIs (Exploding Foil Initiator) beeinflusst werden kann. Im Fall eines kompakten Zündsystems mit zwei Zündkreisen ergeben sich hieraus weitere Maßnahmen, um eine Auslösung des Detonators bei Versagen des Deflagrators und somit dem Ausbleiben der Deflagrationsinitiierung zu unterdrücken. Neben dem Ausbleiben der Deflagration der Wirkladung könnte auch eine vorzeitige Detonation zu einer stärkeren Ausgangsleistung führen. Die nachfolgend beschriebenen Maßnahmen konzentrieren sich allerdings in erster Linie auf den ersten Fall.The advantages of the proposal are that the functional reliability of the ignition system can be influenced both by circuitry and by suitable selection of the electrical components and the one-shot devices such as detonators and Exploding Foil Initiator (EFIs). In the case of a compact ignition system with two ignition circuits resulting from this further measures to trigger of the detonator in case of failure of the deflagrator and thus to suppress the lack of deflagration initiation. In addition to the failure of the deflagration of the active charge, premature detonation could also lead to a stronger output. However, the measures described below focus primarily on the first case.

Hierzu können Maßnahmen wie die Verschaltung des Minimummodus als Standardeinstellung nach Schärfung des Zündsystems, eine redundante Auslegung des Deflagrators mit Hochspannungszündkreisen und pyrotechnischen Ausgängen oder auch eine räumliche Separierung der Hochspannungszündkreise von Deflagrator und Detonator beitragen.For this purpose, measures such as the interconnection of the minimum mode as a default after tightening the ignition system, a redundant design of the deflator with Hochspannungszündkreisen and pyrotechnic outputs or a spatial separation of the high voltage ignition circuits of deflator and detonator contribute.

Vorausgesetzt wird auch, dass geeignete Maßnahmen getroffen werden, um eine sympathetische Initiierung und / oder elektrische Triggerung zwischen Deflagrator und Detonator zu verhindern. Dies kann durch das Zündsystemdesign und geeignete Materialauswahl für entsprechende Barrieren zur Schockdämpfung erfolgen. Das Risiko des elektrischen Übersprechens kann schaltungstechnisch durch die Trennung der elektrischen Energieversorgung und durch Masseverbindungen sowie Isolatoren wie Optokopplern zwischen Niedrig- und Hochspannungsteil des Zündsystems verringert werden.
Als Messeinrichtung können Druck-, Temperatur-, optische oder elektrische Sensoren oder Sensoren, die die Änderung mechanischer Zustände detektieren, zum Einsatz kommen. Diese Sensoren können auch mit einem Entlüftungskanal zur Druckentlastung nach Initiierung der subdetonativen Reaktion kombiniert werden.
It is also assumed that appropriate measures are taken to prevent sympathetic initiation and / or electrical triggering between deflagrator and detonator. This can be done through the ignition system design and appropriate material selection for corresponding shock attenuation barriers. The risk of electrical crosstalk can be reduced circuitry by the separation of the electrical power supply and by ground connections and isolators such as optocouplers between low and high voltage part of the ignition system.
Pressure, temperature, optical or electrical sensors or sensors that detect the change in mechanical states can be used as the measuring device. These sensors can also be combined with a bleed port for venting after initiation of the subdetonative reaction.

Die Messeinrichtung lässt sich vorteilhaft damit kombinieren, dass der Hochspannungskreis für den Detonator erst scharf geschaltet und mit Spannung versorgt wird, sobald das Deflagrationsereignis positiv sensiert wurde. Auch können die Hochspannungszündkreise für Deflagrator und Detonator mit dem Hochspannungskonverter in einer Master-Slave-Anordnung verschaltet sein.The measuring device can advantageously be combined with the fact that the high-voltage circuit for the detonator is first armed and supplied with voltage as soon as the deflagration event has been positively sensed. Also, the high voltage ignition circuits for deflagrator and detonator can be connected to the high voltage converter in a master-slave arrangement.

Durch derartige Maßnahmen lässt sich schließlich die Funktionszuverlässigkeit erhöhen, um eine höhere Leistung des Wirksystems als ursprünglich angewählt oder beabsichtigt zu verhindern. Sie bieten zudem den Vorteil, dass sie sich entweder direkt im oder in räumlicher Nähe des Zündsystems ausführen lassen.Such measures can finally increase the reliability of the function in order to prevent a higher performance of the active system than originally selected or intended. They also offer the advantage that they can be carried out either directly in or in the vicinity of the ignition system.

An embodiment of the invention is illustrated in the figures of the drawing and will be described in more detail below. Show it:
Fig. 1:
a block diagram of a device according to the invention,
Fig. 2:
a possible arrangement of the modules in the field of ignition.

In der Figur 1 ist schematisch vereinfacht ein Blockschaltbild der Vorrichtung gemäß der Erfindung dargestellt. Ein Hochspannungsnetzteil HS-NT versorgt nicht nur die Steuerungseinrichtung ZS-ST für das Zündsystem, sondern auch beide Zündsysteme ZS-A und ZS-B, die EFI's EFI und die Zündketten ZK-A und ZK-B.In the FIG. 1 is shown schematically simplified a block diagram of the device according to the invention. A high-voltage power supply unit HS-NT not only supplies the control system ZS-ST for the ignition system, but also both ignition systems ZS-A and ZS-B, the EFI's EFI and the ignition chains ZK-A and ZK-B.

Die Steuerungseinrichtung ZS-ST führt diverse Aufgaben im Rahmen der sicheren Zündauslösung oder der Reduzierung von Gefahren im Fall einer Fehlfunktion bei der subdetonativen Initiierung der Sprengladung aus.The ZS-ST control unit carries out various tasks in the context of the safe ignition triggering or the reduction of dangers in the event of a malfunction in the subdetonative initiation of the explosive charge.

Hier wird zum einen die zeitlich gesteuerte Verteilung von elektrischer Energie in Form von Niederspannung und Hochspannung zur Versorgung der Baugruppen durchgeführt. Von hier werden zum anderen Steuersignale an alle beteiligten Baugruppen gesendet und die von dort empfangenen Antworten ausgewertet.Here, on the one hand, the time-controlled distribution of electrical energy in the form of low voltage and high voltage to supply the modules is performed. From here to the other control signals are sent to all modules involved and evaluated the answers received from there.

In der Steuerungseinrichtung ZS-ST wird das Ausgangssignal des Sensors ZK-A-Ü ausgewertet, welcher die Funktion der ersten Zündkette ZK-A überwacht. Erst wenn die einwandfreie Funktion dieser Zündkette bestätigt wird erzeugt die Steuerungseinrichtung ein Freigabesignal für das weitere Zündsystem ZS-B und die weitere Zündkette ZK-B. Fällt eine der Baugruppen mit Fehlfunktion aus wird die detonative Initiierung der Sprengladung konsequent verhindert.In the control device ZS-ST, the output signal of the sensor ZK-A-Ü is evaluated, which monitors the function of the first ignition ZK-A. Only when the proper function of this ignition chain is confirmed does the control device generate an enable signal for the further ignition system ZS-B and the further ignition chain ZK-B. If one of the modules fails, the detonative initiation of the explosive charge is consistently prevented.

Die Skizze in Figur 2 stellt stark vereinfacht die örtliche Lage der Baugruppen in einer möglichen Ausführungsform eines Zündsystems gemäß der Erfindung dar. Im zentralen Bereich der etwa zylindrischen Gesamtanordnung befinden sich die bereits genannten Baugruppen der Zündeinrichtungen. Rechts ist die Stromversorgung HS-NT erkennbar, daneben die Steuerungseinrichtung ZS-ST. Weiter nach Links folgen nacheinander die verschiedenen Intensitätsstufen der beiden Zündketten. Ganz links wäre die nicht dargestellte Sprengladung platziert.The sketch in FIG. 2 represents greatly simplified, the local position of the assemblies in a possible embodiment of an ignition system according to the invention. In the central region of the approximately cylindrical overall arrangement are the already mentioned assemblies of the ignition devices. On the right is the power supply HS-NT visible, next to the control unit ZS-ST. Next to the left follow the different intensity levels of the two ignition chains. Far left, the unillustrated explosive charge would be placed.

Zur Druckentlastung bei der Initiierung sind um die zentral angeordneten Baugruppen Entlüftungskanäle angeordnet, die auf der rechten Seite in die freie Umgebung münden. Beispielhaft wurde dort der Sensor ZS-A-Ü platziert, der die ordnungsgemäße Funktion der Zündkette ZK-A detektiert und dies an Steuereinheit ZS-ST meldet. Erst dann wird das zweite Zündsystem ZS-B und die dazugehörige Zündkette ZK-B freigegeben.For pressure relief during the initiation venting channels are arranged around the centrally arranged modules, which open on the right side in the open environment. By way of example, the sensor ZS-A-Ü was placed there, which detects the proper function of the ignition chain ZK-A and reports this to the control unit ZS-ST. Only then is the second ignition system ZS-B and the associated ignition chain ZK-B released.
