Description

Die Erfindung betrifft ein Landminensystem mit durch Fernsteuerung zu steuernden Minen, die jeweils einen Signalempfänger enthalten.The invention relates to a land mine system with mines to be controlled by remote control, each containing a signal receiver.

Panzer- und Schützenabwehrminen, kurz "Landminen" genannt, dienen in steigendem Maße der Sicherung eigener Bereiche. Ihrem Wesen nach sind Minenfelder Defensivmaßnahmen. Sie sind aber auch Teil des gesamten Kampfgeschehens. Dabei besteht oftmals die Aufgabe, in bestimmten Gebieten zu bestimmten Zeiten Sperren, z.B. in Form von Minen, einzurichten. Diese sollen aber nach definierten und vorgegebenen Zeiten beseitigt werden, um den eigenen Truppen die Möglichkeit des freien Han­dels über die Minensperren hinaus wieder zu ermög­lichen. Dies geschieht, indem man die Minen in ihrer Wirkungsfunktion beseitigt. Dazu wurde die herkömmliche Mine von Hand geräumt. Die modernen Minen enthalten Einrichtungen der zeitlich vorgegebenen Selbsträumung durch Detonation oder die "Sterilisation" durch Abschalten des Funktionsmechanismus. Im letzteren Falle sind die Minen inaktiv, können wieder aufgenommen und ggf. relaboriert werden. Es zeigt sich jedoch, daß damit nicht das gesamte Spektrum taktischer Notwendig­keiten abgedeckt wird. Diese verlangen vielmehr - zumin­dest für besondere Bereiche eines Minenfeldes - die Möglichkeit eines beliebigen Wählens vom Zustand der "Schärfe" zum Zustand der "Entschärfung", d.h. der Inaktivität. Da es sich um große Minenfelder handelt, kommen nur weitreichende Fernsteuerungseinrichtungen in Betracht. Dazu bieten sich Systeme auf der Basis von Funkwellen oder von akustischer oder seismischer In­formationsübertragung an.Anti-tank and anti-rifle mines, or "land mines" for short, are increasingly used to secure their own areas. By their nature, minefields are defensive measures. But they are also part of the overall fighting. The task is often to set up barriers in certain areas at certain times, for example in the form of mines. However, these should be removed after defined and predetermined times in order to enable the own troops to freely trade beyond the mine locks again. This is done by eliminating the function of the mines. The conventional mine was cleared by hand. The modern mines contain facilities for self-clearing by detonation or "sterilization" Switching off the functional mechanism. In the latter case, the mines are inactive, can be resumed and, if necessary, relaborated. However, it turns out that this does not cover the entire spectrum of tactical necessities. Rather, these require - at least for special areas of a minefield - the possibility of arbitrary selection from the state of "sharpness" to the state of "defusing", ie inactivity. Since the mine fields are large, only far-reaching remote control devices can be considered. Systems based on radio waves or acoustic or seismic information transmission are suitable for this.

Bei Minen, die unter der Erde oder in Erdfurchen ver­legt werden, erschwert die Erdschicht den Zugang von Funkwellen zu den Minen, so daß nicht sichergestellt ist, daß die Minen die ausgesandten Steuersignale empfangen. Eine vollständig sichere Entschärfung ist aber unbedingt erforderlich, um das Minenfeld passier­bar zu machen. Die Anwendung seismischer Verfahren zum Steuern der Minen ist wegen der unbestimmten seis­mischen Eigenschaften des Untergrundes nicht möglich. Es ist bisher nicht gelungen, eine sichere Schärfung und Entschärfung aller Minen eines Minenfeldes zu gewährleisten.In the case of mines which are laid underground or in earth furrows, the layer of earth impedes the access of radio waves to the mines, so that it is not ensured that the mines receive the transmitted control signals. A completely safe defusing is absolutely necessary to make the minefield passable. The use of seismic methods to control the mines is not possible due to the undetermined seismic properties of the subsurface. So far, it has not been possible to ensure that all the mines in a minefield are safely sharpened and defused.

Der Erfindung liegt die Aufgabe zugrunde, ein Land­minensystem der eingangs genannten Art zu schaffen, bei dem alle Minen unabhängig von dem Ort ihrer Verlegung und unter weitgehender Ausschaltung ungünstiger Über­tragungsverhältnisse von den Steuersignalen erreicht werden können.The invention has for its object to provide a land mine system of the type mentioned, in which all mines can be reached regardless of the location of their installation and largely eliminating unfavorable transmission conditions from the control signals.

Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß eine entlang mehrerer Minen verlegbare Signalleitung vorgesehen ist, die mit den Signal­empfängern der Minen gekoppelt ist.According to the invention, this object is achieved by providing a signal line that can be laid along several mines and that is coupled to the signal receivers of the mines.

Bei dem erfindungsgemäßen Landminensystem werden die von einem Steuergerät ausgehenden Steuersignale einer Signalleitung zugeführt, die entlang der Minen verlegt ist und mindestens in der Nähe einer jeden Mine eine Signalabstrahlung oder -abzweigung verursacht, die die betreffende Mine erreicht. Auf diese Weise ist es mög­lich, Minen im Erdboden oder in Erdfurchen zu verlegen und dennoch durch die Signalleitung sicherzustellen, daß die Signalübertragung vom Steuergerät zu jeder einzelnen Mine mit der erforderlichen Qualität erfolgt. Die Signalleitung stellt die Signalverbindung mit den einzelnen Minen her und trägt die Signale in den Nah­bereich der Minen.In the land mine system according to the invention, the control signals emanating from a control device are fed to a signal line which is laid along the mines and, at least in the vicinity of each mine, causes a signal radiation or branch which reaches the mine in question. In this way it is possible to lay mines in the ground or in furrows and still ensure through the signal line that the signal transmission from the control unit to each individual mine takes place with the required quality. The signal line establishes the signal connection with the individual mines and carries the signals in the vicinity of the mines.

Die Kopplung der Signalempfänger der Minen mit der Signalleitung kann durch galvanischen Kontakt erfolgen, vorzugsweise jedoch durch hoch- oder niederfrequente elektromagnetische Wellen, die eine berührungslose Signalübertragung ermöglichen. Bei berührungsloser Signalübertragung wird die Signalleitung in der Nähe der Minen verlegt, ohne mit diesen in Kontakt zu kom­men. Dies hat den Vorteil einer einfacheren Verlegungs­technik; außerdem können die bei galvanischer Kopplung möglichen Drahtbrüche in den Abzweigleitungen nicht zu Funktionsstörungen führen. Durch die räumlich begrenzte Empfangscharakteristik der Signalempfänger der Minen wird auch sichergestellt, daß Fremdsignale die Minen nicht beeinflussen.The signal receivers of the mines can be coupled to the signal line by means of galvanic contact, but preferably by means of high- or low-frequency electromagnetic waves which enable contactless signal transmission. In the case of non-contact signal transmission, the signal line is laid near the mines without coming into contact with them. This has the advantage of a simpler laying technique; in addition, the wire breaks in the branch lines that are possible with galvanic coupling cannot lead to malfunctions. The spatially limited reception characteristics of the signal receivers of the mines also ensure that external signals do not affect the mines.

Beim Verlegen mit einem Pflug kann die Signalleitung in die Pflugfurche gelegt werden. Bei Punktverlegern bietet sich eine oberirdische Verlegung zwischen den Minen an, um am Platz der Mine selbst in die Erde ge­führt zu werden. Es ist auch möglich, an einem Verlege­gerät, das die Minen einzeln eingräbt, einen Pflug an­zubringen, der die Furche zur Verlegung der Signal­leitung pflügt.When laying with a plow, the signal line can be placed in the plow furrow. For point installers, an above-ground installation between the mines is recommended in order to be led into the ground at the site of the mine itself. It is also possible to attach a plow to a laying device that digs the mines individually, which plows the furrow for laying the signal line.

Im Rahmen der Erfindung können einzelne Gruppen oder Teilgruppen von Minen separat angesteuert werden. Hier­zu enthalten die Signalempfänger Dekodierer zum Erken­nen kodierter Signale, die von einem Steuergerät an die Signalleitung gelegt werden. Auf diese Signale sprechen nur diejenigen Minen an, deren Steuergeräte auf den jeweiligen Code reagieren.Within the scope of the invention, individual groups or subgroups of mines can be controlled separately. For this purpose, the signal receivers contain decoders for recognizing coded signals which are applied to the signal line by a control device. Only those mines whose control units react to the respective code respond to these signals.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, daß die Minen Sender zum Übermitteln von Zustandssignalen von den Minen an die Signalleitung enthalten und daß ein an die Signalleitung angeschlos­senes Steuergerät einen Empfänger zum Empfangen und Auswerten der Zustandssignale aufweist. Hierbei werden Datenflüsse in beiden Richtungen erzeugt. Es besteht die Möglichkeit, die einzelnen Minen auf ihren Be­triebszustand hin abzufragen, um beispielsweise zu er­mitteln, ob sämtliche Minen im unscharfen Zustand sind.According to a preferred development of the invention, it is provided that the leads contain transmitters for transmitting status signals from the leads to the signal line and that a control device connected to the signal line has a receiver for receiving and evaluating the status signals. Data flows are generated in both directions. It is possible to query the individual mines for their operating state, for example to determine whether all the mines are in the unset state.

Im folgenden werden unter Bezugnahme auf die Zeichnun­gen Ausführungsbeispiele der Erfindung näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to the drawings.

Es zeigen:

  • Fig. 1 einen Vertikalschnitt durch einen Teil eines Minenfeldes, bei dem die Minen in Furchen verlegt sind und die Signalleitung aus einem elektrischen Leiter besteht,
  • Fig. 2 einen Teil eines Minenfeldes mit in Furchen verlegten Minen, wobei die Signalübertragung durch einen Lichtleiter erfolgt,
  • Fig. 3 einen Teil eines Minenfeldes mit durch Punkt­verleger verlegten Minen und Signalübertra­gung mit einem Draht und
  • Fig. 4 eine ähnliche Darstellung wie Fig. 3, wobei die Signalübertragung mit einem Lichtleiter­kabel erfolgt.
Show it:
  • 1 is a vertical section through part of a minefield, in which the mines are laid in furrows and the signal line consists of an electrical conductor,
  • 2 shows a part of a mine field with mines laid in furrows, the signal being transmitted through an optical fiber,
  • Fig. 3 shows a part of a mine field with mines laid by point installers and signal transmission with a wire and
  • Fig. 4 is a representation similar to Fig. 3, wherein the signal transmission takes place with an optical fiber cable.

In den Zeichnungen ist jeweils der gewachsene Boden mit 10 bezeichnet und die aufgeworfene bzw. eingefüllte Bodenschicht mit 11.In the drawings, the grown soil is designated by 10 and the raised or filled soil layer by 11.

Gemäß Fig. 1 sind in einer Bodenfurche, die beispiels­weise mit einem Pflug erzeugt worden ist, mehrere Minen 12 verlegt. Ferner ist in die Bodenfurche die Signallei­tung 13 lose eingelegt, die hier aus einem elektrisch leitenden Draht besteht. Die Bodenfurche kann an­schließend wieder zugeschüttet bzw. geglättet werden.1, several mines 12 are laid in a soil furrow that has been produced, for example, with a plow. Furthermore, the signal line 13 is loosely inserted in the soil furrow, which here consists of an electrically conductive wire. The soil furrow can then be filled in again or smoothed.

Das eine Ende der Signalleitung 13 ist an das Steuer­gerät 14 angeschlossen, das Steuersignale in Form von Impulsen an die Signalleitung legt. Jede Mine 12 ent­hält einen Signalempfänger 15, zweckmäßigerweise an der Oberseite des Minengehäuses, und eine Verarbeitungs­ schaltung 16 sowie ggf. einen (nicht dargestellten) Sensor, der auf Annäherung von Objekten reagiert. Wenn das Steuergerät 14 Stromsignale in die Signalleitung 13 schickt, entsteht um die Signalleitung herum ein ent­sprechendes Magnetfeld, das von den Signalempfängern 15 der in der Nähe der Signalleitung angeordneten Minen erkannt wird. Damit in der Signalleitung 13 ein Strom fließen kann, ist das dem Steuergerät 14 abgewandte Ende dieser Signalleitung geerdet.One end of the signal line 13 is connected to the control unit 14, which applies control signals in the form of pulses to the signal line. Each lead 12 contains a signal receiver 15, expediently on the top of the lead housing, and processing circuit 16 and possibly a (not shown) sensor that responds to the approach of objects. When the control device 14 sends current signals into the signal line 13, a corresponding magnetic field arises around the signal line, which is recognized by the signal receivers 15 of the mines arranged in the vicinity of the signal line. So that a current can flow in the signal line 13, the end of this signal line facing away from the control device 14 is grounded.

Durch entsprechende Signale, die über die Signalleitung 13 zu den Minen 12 übertragen werden, können diese Minen scharfgeschaltet oder entschärft werden. Es ist auch möglich, die Minen einzeln oder gemeinsam durch Steuersignale zur Detonation zu bringen.Appropriate signals, which are transmitted via the signal line 13 to the mines 12, these mines can be armed or disarmed. It is also possible to detonate the mines individually or together using control signals.

Jede Mine kann zusätzlich mit einem (nicht dargestell­ten) Sender versehen sein, der Signale in Form elektro­magnetischer Wellen erzeugt, welche von der Signallei­tung 13 aufgenommen und an das Steuergerät 14 über­tragen werden. Auf diese Weise können Zustandssignale von jeder Mine zum Steuergerät 14 übertragen werden, um den jeweiligen Betriebszustand der Mine anzugeben.Each mine can additionally be provided with a transmitter (not shown) which generates signals in the form of electromagnetic waves which are picked up by the signal line 13 and transmitted to the control device 14. In this way, status signals can be transmitted from each mine to the control device 14 in order to indicate the respective operating status of the mine.

Bei dem Ausführungsbeispiel der Fig. 2 besteht die Signalleitung 13 aus einem Lichtleiterkabel, das min­destens eine Lichtleiterfaser enthält. Die vom Steuer­gerät 14 erzeugten Impulssignale werden als Licht­signale erzeugt, die von der Signalleitung 13 über­tragen werden. Im Zuge der Signalleitung 13 sind mehrere Wandler 17 vorgesehen, die die Lichtsignale in Radiowellen umsetzen und diese Radiowellen abstrahlen. Die Signalempfänger 15, die auf die Radiowellen rea­gieren, sind jeweils im Nahbereich eines Wandlers 17 angeordnet.In the embodiment of FIG. 2, the signal line 13 consists of an optical fiber cable that contains at least one optical fiber. The pulse signals generated by the control device 14 are generated as light signals which are transmitted by the signal line 13. In the course of the signal line 13, a plurality of transducers 17 are provided which convert the light signals into radio waves and radiate these radio waves. The signal receivers 15, which react to the radio waves, are each arranged in the vicinity of a transducer 17.

Bei den Ausführungsbeispielen der Figuren 3 und 4 ist jede Mine 12 in einem Minenloch verlegt, das mit einem Punktverleger in den gewachsenen Boden 10 gebohrt und anschließend die Minenverlegung mit lockerem Boden 11 aufgefüllt worden ist. Vor dem Einfüllen des Bodens 11 ist die Signalleitung 13 so verlegt worden, daß sie auf dem gewachsenen Boden 10 liegt und in jedes Minenloch 18 unter Bildung einer Schleife hineinragt. Der durch­hängende Teil einer jeden Schleife erstreckt sich bis in die unmittelbare Nähe der Mine bzw. des Signal­empfängers 15 und kann auch in Berührungskontakt mit dem Signalempfänger kommen. Nach dem Zuschütten des Minenlochs 18 liegen nur noch die nicht-versenkten Abschnitte der Signalleitung 13 an der Erdoberfläche. Durch Verfolgen der Signalleitung der Signalleitung 13 können auch die Positionen, an denen die Minen ver­graben worden sind, leichter aufgefunden werden.In the exemplary embodiments in FIGS. 3 and 4, each lead 12 is laid in a lead hole which has been drilled into the grown ground 10 using a point applicator and then the lead laying has been filled with loose ground 11. Before filling the bottom 11, the signal line 13 was laid so that it lies on the grown bottom 10 and protrudes into each mine hole 18 to form a loop. The sagging part of each loop extends into the immediate vicinity of the mine or the signal receiver 15 and can also come into contact with the signal receiver. After the mine hole 18 has been filled in, only the non-submerged sections of the signal line 13 lie on the surface of the earth. By tracking the signal line of the signal line 13, the positions where the mines have been buried can also be found more easily.

Während gemäß Fig. 3 die Signalleitung 13 aus einem elektrischen Leiterdraht besteht, ist die Signalleitung in Fig. 4 ein Lichtleiterkabel, in dessem Verlauf mehrere Wandler 17 der anhand von Fig. 2 beschriebenen Art angeordnet sind. Jeder Wandler 17 bildet das untere Ende einer in einem Minenloch 18 herabhängenden Schleife. Er ist unmittelbar über der Mine 12 angeord­net. Wenn die Signalleitung 13 ein Lichtleiterkabel ist, enthält dieses natürlich die elektrischen Leitun­gen für die Stromversorgung der Wandler 17.3, the signal line 13 consists of an electrical conductor wire, the signal line in FIG. 4 is an optical fiber cable, in the course of which several transducers 17 of the type described with reference to FIG. 2 are arranged. Each transducer 17 forms the lower end of a loop hanging in a mine hole 18. It is arranged directly above the mine 12. If the signal line 13 is an optical fiber cable, this naturally contains the electrical lines for the power supply of the converter 17.
