Abstract
The present invention provides an automatic target reporting device which is composed of target drones and a controller, wherein the target drones are spliced into a desired target surface by a plurality of steel target plates mutually isolated by vibration insulation layers. The target plates are arranged on a bottom plate with the vibration insulation layers, and a miniature voice recording mike is arranged on the back face of each target plate to be used as a voice sensor. Signals output by the miniature voice recording mikes are transmitted to the controller. The service life of the automatic target reporting device is free from the limitation of hit numbers. The present invention can be used for reporting targets of different bullets by regulating the sensitivity of the controller. The present invention is particularly suitable for reporting targets of non-armor-piercing bullets with a low speed. The present invention can be used for military training and game recreational industry.
Description
The present invention proposes a kind of automatic hit teller, comprises target and controller.What relate to fixed target hits indication mechanism (F41J 1/16, and F41J 5/00).
Automatic hit teller all comprises target and control circuit two partly at least.At present the automatic hit teller of public offering and use by conductive soleplate and with it the conductive rubber target plate of electric insulation constitute target, be combined into required target surface with polylith conductive rubber target plate with different size and shape.When hitting, the metal bullet penetrates conductive rubber target plate and base plate and forms instantaneous short circuit, and control circuit occurs in according to short circuit to be judged between which piece conductive rubber target plate and the base plate and hit number of rings, carries out real-time indication of shots.
The problem that this automatic hit teller exists at first is to hit at every turn and all forms a shell hole on target plate, and shell hole is many will to make reliability decrease.That is to say, be subjected to the restriction of hit-count its service life.Secondly, this hit teller only is applicable to the indication of shots of the metal bullet that can penetrate target plate, and the length of bullet is had certain requirement, so its scope of application is limited.
Purpose of the present invention is just in order to solve weak point of the prior art, and proposed a kind of automatic hit teller that is applicable to various bullets, solve automatically the identification bullet and land the technical barrier in zone, and make do not receive a mandate its service life in the restriction of number of times.
The object of the present invention is achieved like this.
The present invention adopts the steel target plate that hardens, utilize sound wave that bullet and target plate when bump the produce subregion that the difference of spread speed and attenuation degree realizes point of impact in different material, utilize sonic transducer (for example miniature recording microphone) to pick up this sound wave as hiting signal.The automatic hit teller that is proposed also is made of target and controller.Different is: the steel target plate that hardens that target of the present invention is isolated mutually with polylith is combined into required target surface.These steel target plates are installed on the base plate that has vibration insulation.Sonic transducer all is equipped with at the every steel target plate back side, and this signal of sensor is sent into said controller.
When bullet hit a certain steel target plate on the target, because the hardness of target plate is higher than the hardness of bullet, bullet can not penetrate this steel plate.But the sound wave that the two bump produces rapidlyly and undampedly propagates in the sonic transducer that is fixed on its back side along this steel target plate, makes it to produce audio signal output.The audio signal that controller sends according to different sonic transducers is exported the zone of judging that bullet hits, and carries out indication of shots.
Owing between each steel target plate of composition target, and all be provided with vibration insulation between steel target plate and the base plate, obviously decay and delay when sound wave passes through this vibration insulation.The threshold values of adjusting controller just can this signal of propagating by bypass of filtering, avoids reporting by mistake.
The present invention has 1 width of cloth accompanying drawing, is most preferred embodiment of the present invention, also can make the accompanying drawing of specification digest.
The pie graph of Fig. 1 automatic hit teller.
Compared with prior art, automatic hit teller of the present invention can not penetrate target plate because of bullet, The restriction of number of times in Gu do not receive a mandate its service life. By adjusting sonic transducer and controller Sensitivity can be used for the indication of shots of various different bullets and shooting mode, applied range General. Especially it also is specially adapted to the indication of shots of the non-armour-piercing bullet of low speed, therefore can be for military Training and Entertainment are already used.
Below will contrast accompanying drawing and describe formation of the present invention in conjunction with the embodiments in detail.
As shown in Figure 1, the steel target plate 1, vibration isolation plate 4 and the base plate 9 that are hardened by polylith of the target of automatic hit teller of the present invention constitutes.Not of uniform size, the different steel target plate of polylith is combined into the target surface of required form, and is fixed with sonic transducer 2 at the back side of every steel target plate.Can be connected between the steel target plate 1 and vibration isolation plate 4, vibration isolation plate 4 and base plate 9.But between steel target plate and base plate, then must avoid directly being rigidly connected and contacting, propagate to prevent the connector that sound wave passes through between the two.Present embodiment adopts indirect method of attachment as shown in Figure 1, promptly adopts bolt to be connected between vibration isolation plate and steel target plate, and the employing screw is connected between base plate and the vibration isolation plate.For this reason, the position of corresponding each bolt need be left and dodge hole 10 on the base plate.Present embodiment adopts the rubber slab with certain intensity to make said vibration isolation plate.Between each steel target plate, be filled with rubber or other low-density elastomeric materials 5, so that absorb the acoustic propagation between each piece target plate.
Can also realize the connection between base plate, rubber slab and the target plate with the method for bonding.
The sonic transducer 2 that is installed in each piece steel target plate 1 back side adopts miniature recording microphone.Utilize pressure ring 3 and screw that its sound surface is pressed on the back side of each piece target plate 1, enter by airborne sound wave preventing.
The output of the miniature recording microphone that each is such is connected respectively to a preamplifier 7.The acoustical signal that hits after preamplifier 7 amplifies and shaping after be sent to single-chip microcomputer 8, pass to single-chip microcomputer 6 through transmission cable 11 again and analyze identification, and quote shooting result automatically.
Adjust the sensitivity of preamplifier or the pressure between recording microphone and target plate, can be used to survey the bump sound wave of varying strength.Utilize this method, can make hit teller of the present invention be widely used in the automatic target-indicating of different gunnery techniques.
