Abstract
The utility model provides a multilayered sectored light screen bullet projection positioning target surface, and provides a novel ball firing bullet impact point positioning scheme. A plurality of semiconductor laser light sources (1) (two in such embodiment) capable of generating sectored light screen and a signal collection and control circuit are installed inside a hollow metallic target frame (5). The sectored light screen generated from the light sources (1) is emitted out from an emergent light window on the inner side of the target frame (5), covered on a target window (4), and emitted into an incident light window (6) on the other inner side of the target frame corresponding to the target window (4) to correspondingly irradiate light sensitive tube banks (3) arranged on coordinate plates XA8, YA11, XB9 and YB2. When a bullet (10) passes thought the light screen, the sectored light screen naturally projects the bullet and generate a corresponding photoelectric signal. The projection length and position have unique definitive geometrical relationship with the bullet impact point, so that automatic real-time bullet impact point positioning can be conducted by collecting the generated photoelectric signal and processing with a computer, thereby achieving automatic target scoring.
Description
Affiliated technical field
The utility model is the target surface that can detect point of impact and automatic target-indicating automatically that ball firing training uses. the projection that is produced on photosensitive tube row when it utilizes bullet to pass multi-layer sector optical curtain detects its corresponding photosignal by the special signal acquisition control circuit and handles the position of determining point of impact on the target surface afterwards through data.
Background technology
At present, the employed automatic inspection hit telling system of a non-physical culture ball firing training main class of commercialization is " sound target ", and it is to utilize to obtain acoustoelectric signal that the aloft shock wave of bullet or bullet produce the disturbance of air and carry out the measuring and calculating of point of impact and location.Acoustical signal mode when " sound target " obtains bullet and passes target surface has two kinds: a kind of is that the operatic tunes is open; Another kind is an operatic tunes closed. wherein the open sound of operatic tunes target requires Mach number M＞1 of bullet when passing target surface, could produce comparatively reliable and stable acoustoelectric signal when generally requiring bullet initial velocity V＞450 meter per seconds, otherwise, the so-called bullet of losing easily takes place fail to report phenomenon.For the gallery based on pistol shooting is inappropriate, because the pistol cartridge speed that existing station house is equipped with is generally 320 meter per seconds, maximum its reference rounds speed of 54 formula pistols of bullet speed also only is about 430 meter per seconds; For operatic tunes closed sound target, though can obtain the bullet acoustoelectric signal of Mach number M＜1, but the seal of the necessary operatic tunes will be got well when requiring to obtain signal, to keep the wherein quietness of air, but after having produced shell hole on the target surface, the hum of shooting environment will enter operatic tunes inside, its inner air is disturbed, to mix mutually with the useful signal that bullet produces and make it to be submerged, thereby cause and lose bullet and fail to report phenomenon, shell hole the more, this situation is more serious, entirely ineffective up to the automatic target-indicating function, and the airtight operatic tunes expense of the target surface that more renews is very high.Because the velocity of sound of air is subjected to the influence of physical environment state bigger, as temperature, humidity etc., therefore its indication of shots error of sound target of that a kind of mode all big (an about caliber) no matter.In a word, utilize the sound target of acoustic fix ranging principle design all to have poor reliability, positioning accuracy is low and operating cost is high defective, and be theoretic birth defects, be difficult to big improvement.
So far the another kind of automatic inspection hit telling system that does not form product yet is to utilize directional light curtain or directional light net mode, when bullet passes directional light curtain or light net, signal acquisition circuit detects the photosignal that light produces bullet projection, locatees the position of point of impact at target surface with this.When bullet passes the light curtain, under the projection of directional light, on the photosensitive tube of the template of correspondence, form in theory the shade with size such as caliber respectively, detect consequent photosignal, can determine the position of point of impact.This kind scheme is good in theory, but realization difficulty technically is very big, for directional light curtain mode, at first be very difficult and involve great expense in order to the manufacturing that produces tens necessary non-circular curve lens of directional light curtain, even the palpus foreign-made, secondly, the target face structure bulky complex of making in this way and extremely fragile, be difficult to adapt to the on-the-spot adverse circumstances of shooting, its high cost also should not be popularized in China.Though light net formula scheme is not used expensive lens, but since the light beam that a large amount of light sources produce separately must be relative with it the corresponding one by one irradiation of photosensitive tube, technical realization difficulty is very big, and its retentivity is also poor, field adjustable, safeguard very difficultly, still be difficult to adapt to the adverse circumstances of ball firing.In addition, because the restriction of dimension of light source, the mesh size of its light net is very big, and is correspondingly, also just very big to the position error of bullet.There is the defective of target face structure bulky complex and poor reliability equally in this mode.The automatic scoring round target system that has again is the video target, and it is to utilize camera the shell hole situation of target surface to be got back to the position of carrying out obtaining after the image processing current shell hole in the computer.Its major defect has: the distance of camera and target surface must long-term keep its precision, guarantee in shooting on-the-spot general being difficult for, and its professional having relatively high expectations when adjusting; Because the requirement of ball firing real-time, the pixel of video camera can not be very high, thus its automatic target-indicating error also big (greater than the width of target surface loop wire, this will produce wrong report), when shell hole coincidence or lap will the anomaly that bullet is failed to report occur losing than greatly the time; Moreover the video target surface all can not move, and this will make the kind of ball firing training and mobility be tied greatly.Also have some so-called automatic scoring round target system, technology is more backward, no longer enumerates at this.The above commercialization or the not used bullet locate mode of automatic scoring round target system of commercialization, all exist position error much larger than target loop wire width (about 1.2mm), lose that bullet is failed to report and the birth defects of poor reliability, so far still do not possess the ability of carrying out formal automatic target-indicating ball firing match, can not carry out the burst-firing that firing rate reaches 10/second yet.
Summary of the invention
Fail to report for thoroughly eliminating the existing ubiquitous bullet of losing of all kinds automatic target-indicating target surface, the indication of shots error is big, poor reliability, birth defects such as cost height, the utility model provides a kind of brand-new bullet targeting scheme, it is multi-layer sector optical curtain bullet projection locating target surface, the core technology of this scheme is: the light that the bullet that passes the light curtain is carried out projection is not existing known parallel rays or light net mode, but adopt the formed sector optical curtain of line source that the bullet that passes is carried out projection, this projection can form the shadow section photosignal of determining on the row of the photosensitive tube on the corresponding template.For improving positioning accuracy and reliability, adopt multi-layer sector optical curtain.
The operation principle of multi-layer sector optical curtain bullet projection locating target surface and core texture scheme are as follows: in the metallic target frame 5 of hollow, a plurality of semiconductor laser line source 1 and signals collecting control circuits that produce sector optical curtain are installed.The sector optical curtain that is produced by light source 1 is penetrated by the emergent light window 7 of target frame 5 inboards, after covering target window 4, inject another inboard incident light window 6 of the target frame relative and with the photosensitive tube 3 corresponding irradiations of arranging on each template XA 8, YA 11, XB 9, the YB 2 with it.Photosensitive tube row 3 on the segment angle summit A of sector optical curtain template XA 8 YA 11 corresponding with it has formed one deck planar light curtain coordinate system A, with the segment angle summit A of its sector optical curtain as this origin of coordinates that is; Photosensitive tube row 3 on the segment angle summit B of sector optical curtain template XB 9 YB 2 corresponding with it has formed another layer plane light curtain coordinate system B, with the segment angle summit B of its sector optical curtain as this origin of coordinates that is.In like manner, can increase the number of plies of light curtain coordinate system in a similar fashion, with the reliability and the precision of further raising automatic target-indicating.Also be the segment distance L of being separated by between each layer sector optical curtain between each layer light curtain coordinate system, each template is made of the photosensitive tube row 3 who vertically arranges on signals collecting control circuit board and the circuit board, and the photosensitive tube of arrangement aligns with corresponding sector optical curtain.Each light curtain coordinate system is in respectively in the different aspects, works alone separately.This example has two-layer light curtain coordinate system.The hollow region that metallic target frame 5 inboards surround is the effective fire scope of target surface, it is target window 4, when bullet 10 passes each layer sector optical curtain, sector optical curtain carries out projection naturally to the bullet that flies over, projection boundary rays 12 and 13 forms shadow section W and the H greater than the bullet diameter respectively on the template XA 8 of light curtain coordinate system separately or the row of the photosensitive tube on YA 11 or XB 9 or the YB 2, actual position when the light curtain is passed with bullet in the length of this shadow section and position is unique corresponding, has the geometrical correspondence of determining between them.Detect and obtain the photosignal that produces by shadow section in real time by the signal acquisition circuit on the template, carry out corresponding software and hardware again and handle, can reliably the position of current point of impact on target surface accurately be located in real time, form automatic scoring round target system.
The beneficial effects of the utility model are: owing to do not make directional light that the bullet that passes the light curtain is carried out projection, just do not use to producing the necessary non-circular curve lens that involve great expense of directional light yet, cause target face structure greatly to be simplified, the realization that makes it technically becomes possibility, cost reduces significantly, and reliability and indication of shots precision have obtained abundant assurance.When the light of sector optical curtain carried out projection to passing wherein bullet, its position and size were subjected to the influence of physical environment state hardly, as temperature, humidity etc., thereby its positioning accuracy height and stable performance, this is the important feature that existing sound target can't possess.The target surface of the utility model mode can carry out the burst-firing automatic target-indicating, and the damaged condition of performance and target plate is irrelevant, and operating cost is very low, desirable generation expensive similar imported product, be beneficial in China army, police and relevant universities and colleges and popularize.
