Definitions

  • the invention relates to a mine for combating land vehicles, in particular tanks, with an active charge arranged in a housing and operable by means of an ignition device which can be triggered by a mechanical / electrical pressure sensor.
  • a preferably circular flat part of the mine housing is designed as a sensor surface which is responsive to deflection and to which an electromechanical transducer is assigned. It is particularly advantageous to design the sensor surface like a membrane, ie with a relatively small wall thickness, in order to achieve a very sensitive response to deflection.
  • the invention provides for the region of the housing surrounding the sensor surface to be stiffened by means of ribs which are directed towards the interior of the housing.
  • the sensor surface is limited along its circumference by notches in the form of, for example, grooves, so that the deflection of the other housing parts is largely decoupled from the sensor surface.
  • Both a special element made of spring steel or another material, for example, can be inserted into the outer surface of the mine housing as a membrane-like thin bending or sensor surface, or a correspondingly thin area, possibly delimited by the notches, in the one-piece plastic or else Mine housing upper or lower part made of another suitable material can be provided.
  • the mine housing upper part is provided as a particularly preferred area of the arrangement of the sensor surface, in particular the area located above the active charge.
  • This arrangement is particularly advantageous because when the mine is laid, whether camouflaged in the ground or on the surface of the ground, it cannot be ruled out with complete certainty that voids can be present under the mine.
  • the arrangement above the active charge promotes the desired goal of only triggering if the active charge itself and not just the lead casing is covered by the wheel / chain area of a vehicle to be sensed.
  • the sensor surface only extends over a relatively small area of the active charge surface.
  • a signature can also be emitted on a camouflaged, buried mine when driving in front of 5 at a short distance be, which corresponds approximately to that on a trip, which is due to the fact that in the camouflage material or soil there is a stress or shift in the lateral direction, which can not be easily suppressed in the evaluation of the signals.
  • the measure mentioned ensures that the scatter size of the existing effect on the active charge area can be localized.
  • the invention provides for a piezo quartz as an electromechanical transducer for the deflection system to be attached to the inside of the sensor surface by gluing or in another way.
  • Other converters such as Capacitively or inductively detunable resonant circuits, switches, acceleration sensors, variable resistance paths (strain gauges) or the like can be used, but apart from cost reasons, the piezo quartz has the main advantage that it reacts to deflection in the same way as the sensor surface and, in particular, works passively, therefore none for detection Energy supply needed.
  • the coupling of the sensor surface and piezo quartz according to the invention only registers dynamic changes, whereas a static preload, for example via the temperature change of housing parts or due to the exposure to soil or a water column above the mine, is "forgotten” again after a single signal .
  • the simplest case of a signal evaluation is the evaluation of the signal level. This criterion is then passed on to the ignition electronics. It makes sense to evaluate signals from the sensor only if other sensors provided in the mine also detect a target.
  • the electrical evaluation of the signal can provide that a frequency or bandpass filter for interference suppression is switched into the signal evaluation.
  • a frequency or bandpass filter for interference suppression is switched into the signal evaluation.
  • the active charge 2 is arranged in the housing from the upper part 1a and lower part 1b.
  • the relatively small, thin housing section 3 is the bending membrane or the sensor surface.
  • the relatively large remaining area above the active charge 2 is stabilized by the support ribs 5 against bending stresses.
  • the piezoelectric quartz 4 serving as a physical transducer is arranged in the area of the sensor surface 3 by gluing or another type of fastening.
  • Fig. 1a shows a detail and enlarged representation of the membrane surface 3 with the surrounding annular groove 6 for decoupling the bending surface from the rest of the housing.
  • the support ribs 5 are arranged in a radiation pattern and only covers the sensor surface 3 a very small part of the surface of the active charge, resulting in the advantageous effect described above.
  • the sensor surface 3 with the converter 4 is followed by the amplifier 7 and the bandpass filter 8.
  • the threshold value detector 9 evaluates the amplitude size.
  • the ignition logic pressure information is available at 14
  • the signal processing is improved if the pressure signals are counted or integrated in the comparator 1o and compared with a previously set quantity. This information is available at point 11 when the set quantity is reached. Further vehicle-typical signal analyzes can still be carried out if the distances between the pressure signals and their length are compared with a predetermined time pattern in the further comparator 12. The rated informior is then available at 13.
