1) depend on indication of shots person sentences target experience, and efficiency comparison is low, and cost of labor is high.

2) when on target plate, point of impact is many, marker is difficult to identify new and old shell hole, and indication of shots misses by a mile, and directly affects gunnery training quality.

3) when shooting is not fully completed, mending target person and appear outside pit or when mending target person and watching target plate indication of shots and mend target, if shooting position manager slightly neglects, the most easily occur that gun cock off, cause casualties, potential safety hazard is very big.

4) phenomenon practised fraud easily occurs.

Automatic target-indicating is as the Novel newspaper target technology that the huge advance of modern science and technology grows up.At present, the shooting training equipment behavior pattern of my army is the most backward, and great majority are artificial indication of shots, and minority is automatic scoring round target system.Its main cause is: 1, automatic scoring round target system is high in technological content, and cost is of a relatively high;2, the most domestic automatic scoring round target system technology is not mature enough, and system environments bad adaptability, performance are single, it is impossible to meet military training demand;3, minority simulated training system, can only be simulated training, it is impossible to carrying out ball firing, training quality is difficult to ensure that.

Therefore, shooting training equipment should focus in the research and development of real practical " range firing trains wireless automatic scoring round target system ".

Most domestic research the most only rests on theoretic at present, and the most real product accorded with the demands of the market comes out.For the needs strengthened armed forces relying on science and technology of adaptation, domestic have many units to study this, in succession develops multiclass and shoots automatic scoring round target system: 1, two-layer electrode short circuit sampling system；2, semiconductor electronic target system；3, hit telling system based on image procossing；4, localization by ultrasonic automatic scoring round target system；5, laser automatic scoring round target system；6, electric pole short circuit sampling system.

A lot of problems that the most several hit telling systems all exist, it is the lowest that bullet rate in electric pole short circuit sampling system indication of shots, it is impossible to meets the demand of training and competition.The design of semiconductor electronic target system is simple, and easy maintenance has higher indication of shots degree of accuracy, but owing to price is prohibitively expensive, it is impossible to promote on a large scale and large-scale production.It is simple that hit telling system based on image procossing realizes function, and indication of shots is just, but the precision of indication of shots is low, can not realize synchronizing real-time indication of shots, corresponding the slowest.Localization by ultrasonic automatic scoring round target system is high to environment fitness, it is possible to uses in the complex environments such as dark and electromagnetic interference, has enough indication of shots precision to promote on a large scale.Laser automatic scoring round target system is that current indication of shots precision is best, and zero consumptive material uses, and meets the condition of indication of shots precision and efficiency, it is simply that its cost is slightly higher, it is believed that along with the increase of the time of use, the use of zero consumptive material can make it be more conducive to training and competition.

Detailed description of the invention

As shown in Figure 1, optical target is trained for this utility model range firing, including target frame 10 and the target core 20 that is arranged in target frame 10, photocell matrix module 11 that this target core 20 includes being electrically connected with successively, data acquisition module 12, data processing module 13, wireless transmitter module 14, wireless transmitter module 14 is for sending target practice data to backstage, and described photocell matrix module 11 is made up of the 800 pairs of transmitting tubes being arranged on inside target frame 10 in X-axis, Y direction and reception pipe；

Additionally, optical target is with supply module, owing to power pack is routine techniques, it is not belonging to the protection point of the technical program, therefore not shown in figure.

nullSuch as Fig. 2、Shown in Fig. 3，Optical target is except including target frame 10 and target core 20，Also include target sheet 40、Support column 50、Base 60，Target sheet 40 is fixed on target frame 10 back side，Target sheet 40 is conventional dummy or chest silhouette target，Base 60 it is fixed on bottom support column 50、Top is fixed with target frame 10，Play the effect of fixing target core height，Certainly，Support column 50 may be used without expansion link，It is thus possible to adjust target core height as required，For the ease of mobile and transport，Base 60 is arranged with the universal wheel 70 of four band position-limit mechanisms，Position-limit mechanism can lock universal wheel 70，When preventing from shooting, optical target 1 moves，In addition，Base 60 is additionally provided with the ground nail 80 of two detachable installations，Ground nail 80 is utilized to fix with ground，So that the optical target 1 of the technical program is applicable to irregular landform，Such as mountain region.

Due to target core 20 800 light emitting diodes of the intensive installation of surrounding, 800 light sensitive diodes, when ball firing training, if bullet hits target core 20 frame, bullet can be shot through target frame, destroys photodiode, and firing point is misrepresented deliberately, judged by accident to make this group diode correctly not reflect.Therefore, target frame 10 is the protection housing that shellproof steel make, and the rubber layer 30 that about 50mm is thick is posted on this protection housing surface, and when bullet shooting target frame 10, rubber layer 30 can produce certain cushioning effect, and prevent bullet from rebounding, cause unnecessary accidental injury.

Collimation and the cross-sectional area of light beam are had higher requirements by native system, because needing to install X, each hundreds of the emitting components of Y-direction on the frame of target core 20, this just requires that device volume is little, and light beam, hot spot are little.Infra-red laser diode has characteristics that, utilizes laser diode and lens combination to constitute discharger, can reach preferable effect.Relatively costly in view of high-precision infra-red laser diode, it would however also be possible to employ common, inexpensive light emitting diode replaces, cost can be reduced, depending on the demand of client.

As shown in Figure 4, network structure for photocell matrix module 21, target sheet 40 is placed in network structure rear co-axial, when bullet passes through laser network, and when breaking network structure, (x, y) coordinate change so that receiving pipe (light sensitive diode) on off state to block X, Y both direction Shang Ge tetra-road, corresponding position laser.By encoding light sensitive diode on off state, light sensitive diode state corresponding when just can be passed by bullet carries out record, utilizes single-chip microcomputer to process this signal, just can get coordinate and the number of rings of point of impact.

Wireless hit telling system is to install two sets eight row highly sensitive optoelectronic transceiver device (light emitting diode) in the surrounding of target body with both vertically and horizontally corresponding.Target is divided into the latticed of matrix form by the light that the luminescent device of these two groups of dense arrangements is sent.Each small grid correspond to a square region on target.The each group of combination that both vertically and horizontally photoelectric device is numbered, it is simply that the coordinate of corresponding point on target.Often organizing in the case of adjacent photoelectric device is smaller than bullet diameters, the bullet moment by target body every time, will cut off the light of at least four in the vertical direction and the horizontal direction, the light and shade change of light makes again the electric parameter (such as output level) of sensor devices change.In this manner it is possible to collected the numbering of these sensor devices by programmable devices such as single-chip microcomputers, form point of impact coordinate, obtained the number of point of impact the most again by the mode such as table look-up.Using high-performance diode, by the light net of horizontal 400 and longitudinally 400 diode compositions, the light matrix of 160000 pixels of composition, inside each region the position of corresponding virtual coordinates.Use the core algorithm software oneself independently researched and developed, identify rapidly the rule of correspondence of physical location and virtual location, target practice data are timely, feed back to shooter accurately.

It is known that the running fire speed of 95 formula automatic rifles is less than 800/min, and the running fire speed of general firearms is 1000/min, i.e. bullet target time interval and is about 60ms.This automatic scoring round target system carries out the timing intervals of data acquisition continuously adjustabe in the range of 10S-600 ms.Therefore, the sequencing of bullet when can tell burst-firing in time interval completely, it is possible to realize carrying out data acquisition successively.

For getting rid of the chaff interference impacts on data acquisition such as insecticide, by generating laser in transmitting-receiving array and the X-axis corresponding to receptor pairing, Y-axis is installed in the distance of Z axis (direction that i.e. bullet is sudden) about about the 40mm that staggers, it is much lower that chaff interference movement velocity compares bullet, then the time of signal intensity is the most persistently occurred to distinguish whether chaff interference exists according to photodiode in X-axis and Y-axis, we are in the time-triggered protocol of software, this type of temporal characteristics is screened, thus bomb-release point and external interference thing are made a distinction identifying processing, solve wrong report, the problem misrepresented deliberately.

Whole system is the most succinct, modularized design is prone to debugging, it should be noted that the debugging of photoelectric switching circuit on target, because photodiode, light sensitive diode quantity are more, it is respectively arranged with 800 and makes intensive on printed circuit board being together in series, disturb for anti-natural light, inside the recessed framework of light sensitive diode installation site a bit.

This system requirements photodiode is able to detect that bullet quickly blocks light path This move, and this is mainly determined by the response time of photodiode.Generally the typical length of bullet is more than 1cm, the representative value of bullet speed is 1000m/s, and therefore, the effective length of the light path that is blocked is more than 5 mm, thus show that bullet blocks time of light path and i.e. can meet measurement requirement more than 5ms, the response time of general photodiode less than 0.1ms.Visible, transmitting-receiving photovoltaic array has enough response times to catch the bullet image of injection.

The emission principle of this system wireless transmitter module 14 is: by bullet through the X of photoelectricity array, Y-axis coordinate, by corresponding light resistance break signal coordinate through opto-electronic conversion coded treatment, every impact information sending out bullet can be obtained when burst-firing, the array data collected is transmitted by the serial wireless data transmission module of 433MHz, this module can realize bidirectional transmit-receive, transmission range is in more than 1Km, requirement when can meet field ball firing transmitted shooting.Other end record principle is: after the coordinate signal be given after rear end wireless receiving module 21 receives front end shooting, software is by this signal of Automatic solution, and will restore coordinate point of impact position on computer screen.

The foregoing is only preferred embodiments of the present utility model, this utility model is not limited to above-mentioned embodiment, as long as realizing within the technical scheme of this utility model purpose broadly falls into protection domain of the present utility model with essentially identical means.
