Definitions

  • the invention relates to a target device for simulated shooting according to the preamble of claim 1.
  • a target device of the type mentioned is known for example from CH-PS 612 004.
  • the rings and the center are designed as photodetectors, preferably phototransistors, the rings each being designed as roller collectors and the sectors accordingly as emitters. Since such phototransistors cannot be formed over a larger area, the known target device must be provided with a converging lens the size of the target so that impinging radiation pulses are redirected to a small detection area and combined. Apart from the fact that such a device has a relatively complicated structure, an exact evaluation of the hit is practically impossible.
  • a target arrangement which along the X or. Y-axis has photodetectors that are combined into groups and evaluated.
  • the photodetectors are connected to drive circuits for the controlled generation of excitation signals.
  • the photodetectors hit by a light beam from a weapon accordingly generate pulsed signals which are evaluated using very complicated methods and corresponding device parts.
  • This target arrangement is extremely complicated and therefore not only expensive but also prone to failure. Otherwise, the target arrangement should only be suitable for targets and hits where the hit hits at least one of the X or Y axes.
  • the target arrangement is completely unsuitable for small hit diameters and large targets.
  • the object of the invention is to design a target device of the type mentioned at the outset in such a way that it has a simpler structure and can evaluate hits with greater accuracy.
  • a target in its original size is equipped with photodetectors in such a way that at least one photodetector is struck by a hit, direct and precise query of the target for hits is possible without these having to be redirected or even reduced.
  • the arrangement of photodetectors on a target is also much easier than the configuration of rings and sectors as photodetectors.
  • the arrangement of the photodetectors along the rings and in the center and the connection of each photodetector on the one hand with a shot value line and on the other hand with a sector line enables a particularly simple evaluation of the hits and thus also a simple, inexpensive and reliable construction of the target device.
  • Hits of the most varied sizes can be evaluated with the target device, wherein those whose hits correspond to the caliber of the weapon are preferably evaluated according to claim 2.
  • a target device according to claim 3 is advantageously suitable for hits that are larger than the caliber of the weapon.
  • a wide variety of components are suitable as photodetectors, but preferably photodiodes according to claim 4, which serve as a current source when the hits occur, so-called photo cells.
  • Such a phototransistor is an optoelectronic semiconductor component in which the current flow is influenced by the internal photo effect.
  • An embodiment according to claim 6 is particularly expedient.
  • an embodiment according to claim 7 is particularly advantageous.
  • the received signal modulated in this way is an AC voltage, which can be separated by a filter from the photo current generated by the ambient light.
  • an embodiment according to claim 8 is advantageous in order to amplify weak signals.
  • a further development according to claims 9 and 10 is also particularly advantageous, which results in a simple design of the evaluation device.
  • Particularly precise evaluation results are obtained by designing the evaluation device according to claim 11.
  • the duration of the display of the sector and / or shot value can be set by means of an embodiment according to claim 12.
  • the embodiment according to claim 13 makes it possible to set the time at which the target device is activated again for a next shot.
  • FIG. 1 shows a target 2 in the cutout, which is suitable for small-caliber weapons at a distance of 10 m, the hit 4 corresponding to the caliber of the weapon.
  • the target 2 has rings R 1 to 10 , of which the ring R10 forms the center and which are each limited by outer circles TA 1 to 10 .
  • the target further contains sectors S 1 to 8 , of which the sectors S 1 and S 2 are shown.
  • the center serving as photodetectors serving phototransistors F 1 to 10 are arranged in such a density that at least one phototransistor from a hit 4 of an optical shot pulse is hit.
  • FIG. 1 shows a target 2 in the cutout, which is suitable for small-caliber weapons at a distance of 10 m, the hit 4 corresponding to the caliber of the weapon.
  • the target 2 has rings R 1 to 10 , of which the ring R10 forms the center and which are each limited by outer circles TA 1 to 10 .
  • the target further contains sectors S 1 to 8 , of which
  • the photo transistors are connected such that the emitters 6 of each photo transistor of a ring R 1 to 10 are connected to a shot value line 8 1 to 10 .
  • the individual phototransistors of a sector are combined via their collectors 10 with a sector line 12 1 to 8 .
  • the collector of the photo transistor F10 of the center is on its own line 14 connected to the signal conditioning instrument.
  • a tens disc with 67.5 mm ⁇ , which is used at 10 m distance for small-caliber weapons 4.5 mm, is equipped with phototransistors as follows:
  • FIG. 3 shows a schematic circuit diagram of the evaluation device, which essentially consists of a power supply unit 16 with a voltage divider 16 for generating the required low-voltage DC voltage, an evaluation part 18 for evaluating the phototransistors and a timer 20a, 20b for determining the duration of the display and the resetting of the Device is built.
  • the evaluation part 18 contains the 197 photo transistors F 1 to 10, which generate a current when a hit 4 hits a shot pulse.
  • the collector 10 is connected via a sector line 12 to one of eight thyristors 22 which have an anode gate, that is to say controlled on the anode side are.
  • the thyristor 22 is conductive by a sector signal and ignites the corresponding sector lamp 24.
  • the photo transistor F hit by the hit 4 is connected with its emitter 6 via a shot value line 8 to a further thyristor 26 controlled on the cathode side, one of which is present per ring.
  • the thyristor corresponding to the struck ring is ignited by a ring signal, thereby supplying a signal to an integrated circuit 28 which contains a memory, for example an EPROM memory, and triggers the associated stored hit display, which is digitally displayed on a hit display device 30.
  • the integrated circuit 28 is designed such that the higher value is always displayed when two or more phototransistors are hit.
  • the duration of the display is determined by the timer 20a, which deletes the display on the hit display device 30 after an adjustable time.
  • the timer 20b activates the evaluation device for a new hit display.
  • the target device is preferably designed such that the phototransistors are tuned to the frequency spectrum, for example 820 nm, of the shot pulse transmitter of the weapon and preferably contain a daylight filter and respond to a shot pulse, preferably clocked at 1 to 3 KHz.
  • the received signal modulated in this way is an AC voltage, which can be separated in a manner not shown by a filter from the photo current generated by the ambient light.
  • FIG. 4 shows a sector-like section from a target with 10 rings R 1 to 10 , which are used for shooting a distance of 300 m is suitable, but the hit 32 does not correspond to the caliber of the weapon, but is larger, for example has a diameter of 80 to 90 mm and hits one or more photo detectors at the same time.
  • the evaluation device determines the center 34 of the hit 32 from the photodetector (s) hit and displays its position when the center 34 is located in one of the rings R 1 to 10 . In the present example, this is the case when the photodetectors F 1 to 9 are arranged on the inner pitch circles TI 1 to 9 of the rings R 1 to 9 .
  • FIG. 5 shows the block diagram of an evaluation device for the target of FIG. 4.
  • This contains a power supply unit 36 with a voltage divider, on which the photodetectors F 1 to 10 of the target and a first determination device 38 for the rings R 1 to 10 and a second determination device 40 for the sectors S 1 to 8 of the target and a timer 42 for determining the duration of the display and the reset of the device are connected.
  • the photo detectors F 1 to 10 are connected on the one hand via shot lines 44 1 to 10 with integrated circuits 46 1 to 10 and on the other hand via sector lines 47 1 to 8 with integrated circuits 48 1 to 8 , the integrated circuits each containing operational amplifiers for the detected hit signals.
  • Series resistors 50 each serve to regulate the sensitivity of the integrated circuits.
  • the integrated circuits amplify the hit signals and pass them on lines 52 1 to 10 to a further integrated circuit 54 which contains a computer and a memory in order to evaluate the hit signals and to pass them on to a digital hit display device 56 for the ring values hit.
  • the integrated circuits 48 give 1 to 8 Sector signals of the hit signals via lines 58 1 to 8 to a second integrated circuit 60 with a memory, which evaluates the sector signals of the hit signals and passes them on to an analog hit display device 62 for the hit sector values.
  • the timer 42 is connected to the first and second integrated circuits 54, 60 via lines 64, 66 in order to control the duration of the display and the resetting of the device.
