Abstract

Prezenta inventie se refera la un procedeu si la un dispozitiv pentru estimarea preciziei de tragere, în special, în cazul concursurilor de tir cu arma la antrenamente si-mai ales-în cazul concursurilor de performanta, cu scopul de a se obtine o precizie superioara a evoluarii rezultatelor, precum si o obiectivitate independenta de aprecieri subiective. Procedeul si dispozitivul pentru estimarea preciziei de tragere, conform inventiei, utilizeaza tinte imprimate pe o banda în care glontele perforeaza o gaura, banda fiind apoi supusa unei analize succesive a doua sisteme independente ortogonale ale unor bariere de lumina, pentru determinarea pe de o parte a coordonatelor gaurii generate de glonte, operatiile sus mentionate fiind facute în mod succesiv si automat prin aceea ca banda cu tinte imprimate si gaura de glonte este deplasata într-o directie longitudinala printr-un prim sistem de bariere de lumina directa, din care se obtine exploatarea si compararea a doua semnale ale marginii gaurii-aflate fata în fata diametral simetric-un semnal al centrului gaurii produse de glonte, iar prin explorarea tranzitiei intensitatii unui flux de lumina reflectata de imaginea tintei de pe banda, ca urmare a variatiei de la culoarea deschisa la cea închisa a centrului tintei, care se produce la cele doua margini ale tintei-aflate, de asemenea, diametral simetric-ce defileaza prin bariera de lumina reflectata mentionata, dînd un semnal al centrului tintei, acesta producîndu-se prin intermediul unor semnale de avans proportionale cu înaintarea relativa a tintei de trageri, atît pentru cazul determinarii centrului gaurii, cît si pentru determinarea centrThe present invention relates to a process and a device for estimating firing accuracy, in particular in the case of shooting competitions with training arms, and especially in the case of performance contests, in order to obtain a higher precision of the evolution of results, and an independent objectivity of subjective appreciation. The method and device for estimating the drawing precision according to the invention uses printed targets on a strip in which the bullets perforate a hole, the band being then subjected to a successive analysis of two orthogonal independent systems of light barriers for determining on the one hand of the bore coordinate generated by the bullets, the above mentioned operations being done successively and automatically in that the printed tape and the bullet hole are displaced in a longitudinal direction by a first direct light barrier system from which the exploitation and comparing two bore edge signals - diametrically symmetrical face to face - a signal of the center of the borehole produced by the bullets, and by exploring the transition of the intensity of a light flux reflected by the image of the target on the band as a result of the variation from the open color at the closed center of the target, which occurs at the two ends of the target, also , diametrically symmetrical-which scrolls through the reflected light barrier mentioned, giving a signal to the center of the target, it being produced by means of proportional feed signals with the relative advance of the target of firing, both for the determination of the center of the hole and for the determination centr
