Definitions

  • the invention relates to a mine according to the% berbegrifi of claim 1.
  • Such a mine is known from DE-A-24 23 912 and from US-A-25 69 888. It can be transferred to a new safety position if the mine, once laid out and in focus, is to be cleared again without detonating it or doing so.
  • the invention has for its object to provide a mine of the generic type in such a way that the flexibility of its possible uses is significantly increased by an easy-to-use security lock against unauthorized demining.
  • a remote mine with a complex ignition sensor such as is described, for example, in US Pat. No. 3,509,791, is intended. Because such a mine initially remains in wait and not switched over to readiness for ignition when, for example, a seismic sensor signals the approach of a target object, the acquisition of which can then be controlled by means of an infrared sensor, the mine is accessible relatively safely by laying teams in order to be able to dismantle it in a place that is no longer needed and to be able to relocate it again. For this purpose, it is necessary that the securing device can be reversibly returned to the securing device, but this should only be possible for authorized persons. Authorized persons are only those who know the code of the security lock, e.g.
  • the predefined and the security code to be entered subsequently for overcoming the lock are expediently stored and compared within the electronic circuit in which the sensor signal processing also takes place, that is to say, for example, by means of further logic operations or information processing in processor-controlled devices.
  • a mine 11 is equipped with an ignition sensor 12 and this downstream ignition signal processing circuit 13 for obtaining a target detection signal 14, which triggers an ignition signal 15 for initiating a combat charge for combating the acquired target object.
  • a safety device 16 ensures that the ignition signal 15 can only be triggered if, after the mine 11 has been suspended, a focusing device 17 has been actuated which, according to the symbolically simplified block diagram in FIG illustrated) delay sets a bistable switching element 18 and thereby prepares an ignition signal output gate 19. Its AND condition is fulfilled, i.e. the gate 19 is switched through when an OR gate 20 supplies a trigger signal 21 because an ignition detection signal 14 from the sensor 12 or a space lock signal 23 from a room lock 22 (for example an inertia switch responsive to tilting of the mine 11) is delivered.
  • a (re) fuse lock 25 is formed within the electronic circuits 24 containing the ignition signal processing 13.
  • This is designed to be able to deliver a reset signal 26 to the bistable switching element 18 in the safety device 16 only when a signal code 28 is entered via an input device 27, which has a specific relation to a predetermined (re) safety code 29, for example, matches him. If this is the case, a comparator 30 responds and triggers the reset signal 26 in order to bring the safety device 16 back into the safe state, that is, to be able to move the mine to another location without the risk of initiating the explosive.
  • the comparator 30 supplies a blocking signal 31 which is again transmitted through the OR gate 20 to switch through the output gate 19, that is to say to output a Ignition signals 15 leads.
  • the comparator 30 contains in particular a coincidence circuit 32 to which a default memory 33 and an input memory 34 for the two codes 29, 28 are connected.
  • the output signal of the coincidence circuit 32 is interrogated by means of an interrogation device 35 and possibly output as an reset signal 26 via an AND gate 36, which returns the safety device 16 from its previous arming to the safe position.
  • a gate 37 with an inverting input switches through if the circuit 32 should not detect any coincidence in order to deliver the blocking signal 31, i.e. to trigger the ignition signal 15 (because an unauthorized person is apparently handling the mine 11 and therefore its combat charge is to be detonated ).
  • the input device 27 can be designed as a reading device, for example for a card with an embossed binary code. This can be stored, for example, as a line pattern, as a magnetization pattern or as a hole pattern on the card 38 and can be read out by the input device 27 serially or in parallel into the input memory 34, whereupon the device 35 is triggered by the input device 27 to acknowledge the query (code acceptance) .
  • a card 38 as an information carrier for entering the codes 28, 29 is particularly expedient if a plurality of mines 11 are laid out in one area, all of which are equipped with a security lock 25 for the same re-security code 29 in order to simplify handling by the mine pioneer are, so that incorrect operations when clearing the minefield by authorized persons are practically excluded.
  • a coding device for the card 38 by means of which a preselectable code 28 is entered (for example printed on by a line pattern stamp or stamped by a simple mechanical hole stamp); with the transfer of this predetermined information from the card 38 by means of the input device 27 into the first memory 34 as the later security code 29.
  • the input device 27 is then operated again, the content of the first memory 34 is transferred to the second memory 33, and the newly read code 28 is transferred to the first memory 34. If the comparator 30 finds agreement between the contents of the two memories 33 and 34, the reset signal 26 is output for the safety device 16 as described. In this way, the information about the predetermined security code 29 is securely protected; in that, for example, a single mine pioneer, after relocating a group of mines 11, stamps optional information as code 28 in the card 38 and stores it in the security lock 25 as the security code 29 valid for that mine group.
  • the input device 27 can, however, also simply be designed as a changeover switch for entering a sequence of binary signals as the codes 29, 28, as sketched in FIG. 2, for example.
  • a pulse sequence is triggered to advance the information when it is entered into the memory 34 (for example to continue probing when the information is transferred to a shift register).
  • the code 28, as considered in Fig. 1, e.g. represents four-bit information the change-over switch 39 has to be operated four times and the code 28 is entered into the first memory 34.
  • the changeover switch 39 is actuated four times in the same way later, in order to cancel the mine 11, the information 28 is transferred from the first memory 34 as the security code 29 into the second memory 33 and the newly entered information as signal code 28 into the first memory 34 adopted in order to then evaluate both memory contents using the comparator 30 as described.
  • the interrogator 35 thus responds when a pulse train 40 of twice four bits has occurred; i.e. it can simply be designed as a counter of the count volume eight for the pulse train 40.
  • FIG. 3 A greatly simplified exemplary embodiment for an electromechanical input device 27 with electrical locking is shown in FIG. 3.
  • Manually actuated, resiliently returned plunger 41 of a keyboard 42 can activate one of two switching options, which are shown as shiftable switch groups 43 to simplify the illustration, of which one switching path 44 for the delivery of a reset signal 26 and another switching path 45 for the delivery of one Fuse lock signal 31 is assigned.
  • the reset switching paths 44 are electrically connected in series. Those who are not in the scope of a Tappet 41 lie. are inevitably closed, for example by means of a device-fixed ramp 46.
  • the other reset switching paths 44 which are thus shifted into the sphere of influence of their assigned plunger 41, are closed by manual actuation of their plunger 41, so that the series connection is then completed and the reset signal 26 is output.
  • a blocking switching path 45 is inevitably assigned to it. If an unauthorized person who does not know the shift position of the switch groups 43, with the intention of switching a reset signal 26 through, also actuates this other plunger 41, a blocking signal 31 is switched through here and the mine 11 is ignited.
  • the mine pioneer shifts its switch groups 43 according to a predetermined security code 29 by lifting a device cover 47 at the security lock 25 and setting the switch groups 43 accessible underneath in the code position. Then the lid 47 is e.g. locked electromechanically by confirming the focusing device 17 (FIG. 1), so that no unauthorized person can open the cover 47 and the switch group sliding position can be memorized; with triggering, for example, the clearing lock 22 when trying to open the lid 47 by force.
  • plungers 41 for example, identified by numbers or colors
  • the reset signal 26 alone (but in no case the blocking signal 31); and unlock the cover 47 again in order to be able to specify a different re-security code 29.
  • the simplified schematic diagram of the drawing does not take into account the fact that it may be expedient to combine the function of the chart setting device 17 with that of, for example, the input device 27: by entering a cancellation code 29, the bistable switching element 18 becomes at the same time (possibly via a delay) set, that is, the safety device 16 focused.
  • the sensor signal processing circuit 13 - or at least the part of it that activates a wake-up circuit for an ignition trigger sensor - can be activated; while the circuit 13 can be switched off again in parallel with the backward control of the safety device 16 into the safe state.
  • the ignition signal 15 is not immediately switched on (in order to trigger a combat charge or a lifting lock) if the signal code 28 is incorrectly entered, but rather to allow the mine pioneer a number of input attempts (specified in terms of circuitry). Only when this number has been exceeded is the ignition signal 15 triggered because apparently no authorized person is attempting to re-secure it. The number of permitted attempts must of course be small in relation to the number of information variants for the cancellation code 29, so that this cannot be determined by the input attempts.
