Definitions

  • the invention relates to a method according to Preamble of claim 1 and a device according to Preamble of claim 6.
  • the invention is therefore based on the object a method for the detection of the firing create what misdetection of the firing for all calibers used in shooting do not occur.
  • the detection of the Projectile through a light curtain It is further preferred if in addition to the passage detection the sound of the firing as a firing criterion is used.
  • the invention is also based on the object to provide a device that the shot delivery detection allowed for all calibers without errors.
  • the figure shows a schematic representation barrel 7 of a weapon, e.g. by one Small bore pistol, a small bore rifle or one other weapon used for sport shooting.
  • the weapon is operated by a shooter who is in lying or kneeling or standing position in the Firing range (in shooting position) is in the shooting range and to a more or less distant target (Target) fires shots from the shooting range.
  • the projectile 1 is further shown, which after the shooter has fired the run 7 has left.
  • the wave fronts 6 are the sound waves specified which of the weapon (muzzle blast) and start from projectile 1.
  • the detection arrangement 2, 3 For the detection of firing is now a detection device in the example shown 2, 3 provided, which on the front, target side End of the shooting range and thus at the firing position the shooter near the muzzle of the weapon is that on the way to the targets located projectile 1, the detection arrangement 2, 3 flies through.
  • the detection arrangement is now designed that they are on the projectile 1 itself or on whose physical characteristics react and not only the secondary effects of the shot, especially the sound waves or the muzzle flash. in the is shown by the detection arrangement 2, 3 creates a complete curtain 4 of light through which the projectile passes through and briefly interrupts.
  • the light curtain is represented by the Sendund lying to the side of the flight axis of projectile 1 Receiving units 2, 3 generated, which to this Purpose with a variety of light transmitters and light receivers are equipped so that a complete light curtain (from visible or invisible light, e.g. infrared light) arises.
  • the generation of the light curtain can by known, commercially available elements take place, which preferably emit laser light Laser diodes and corresponding receiving diodes are formed become.
  • Preferably on both sides of the projectile flight axis both light emitting diodes as well light receiving diodes arranged so that one of Continuous arrangement of light strips on both sides results, which also partially or completely can overlap.
  • the light transmitters and the light receivers can be regularly on a strip-shaped board Distances can be arranged and by means of the circuit board also be wired. These boards are shown in the columnar housings arranged. To this This results in an inexpensive manufacture of the Light emitting and receiving units on both sides of the projectile flight axis.
  • the light curtain could also be from arranged above and below the flight axis of the projectile Transmitting and receiving elements are generated. Prefers is, however, the generation shown by the side transmitting and receiving elements arranged on both sides of the flight axis.
  • Light curtain is in the microsecond range for a short time the light curtain is interrupted or one or more the light bands emitted by the laser diodes is completely or partially interrupted for this short time.
  • the corresponding short-term light drop is from the respective opposite receiving diodes in one correspondingly changing electrical signal implemented.
  • the Signals of all receiving diodes are, individually or in Groups combined, to form a detection circuit 8 given the corresponding change in diode signals detected.
  • the lines from the sending and receiving units 2, 3 to the circuit 8 are in the Figure only schematically with a line in the unit 3rd specified.
  • the detection circuit 8 can also continue for the supply of the laser diodes and if necessary for a modulation of the laser light and one accordingly coordinated detection of the received diode signals, to reduce the influence of unmodulated ambient light.
  • the detection circuit 8 generates from the signals of the receiving diodes a shot firing signal 10, which in the drawing is symbolically represented as a pulse signal, and which to a known control and evaluation unit 9 of an automatic hit display system which, since known per se, is not further here must be explained.
  • This control and evaluation unit processes the firing signal 10 to known ones Way forward to any false reports due to errors to suppress shots fired at wrong targets or display as an error.
  • the detection circuit 8 speaks to the generation of the firing signal 10 only for short-term changes of their input signal originating from the receiving diodes which in the expected time range of a projectile flying through the light curtain 4. Longer breaks in the light curtain, such as they e.g. caused by an insect flying through it which is not the speed of the projectile 1 can be achieved by the detection circuit 8 not taken into account and do not lead to the tax a firing signal 10. As already mentioned, several light curtains 4 arranged one behind the other, so the detection circuit 8 can further consider whether all curtains 4 are within the for the projectile speed flew through the expected period of time or have been interrupted and only then a firing signal Generate 10 if this is the case. With the described Method or the device with the light curtain 4, it is fundamentally possible to make an error-free Firing shot detection to be carried out, since no influences neighboring shooting range or weapons can occur.
  • a microphone 5 is used, which in particular the sound waves of the muzzle blast registered.
  • the output signal of the microphone 5 can are also given to the detection circuit 8. This then analyzes whether after the interruption of the Light curtain within a given time window a sound event arrives at the microphone 5, which for predetermined and adjustable on the detection circuit 8 Weapon type fits. A firing signal is then only generated when both event detections, both on the light curtain 4 as well as through the microphone 5 Show firing. By linking both events can reduce the likelihood of false positives be further reduced. This link could also be take place in the arrangement 9 when the microphone signal is not led to circuit 8, but evaluated separately becomes.
  • a signal to link to the signal The light curtain could be used for such weapons a muzzle flash is visible, also from the known Detection of the same can be obtained.
  • This signal will then instead of the microphone signal as described above used for linking. It is also possible to get one to use such signals in addition to the microphone signal, so that three signals (light curtain, microphone and muzzle flash detection) are linked, to generate a shot firing signal.
