Wall type large target surface bullet coordinate test system

Abstract

The invention discloses a wall-mounted projectile targeting coordinates testing system with a large target surface, which comprises a testing light curtain array of six intersected light curtains, a data collecting and analyzing system, a computer and display processing software. The wall-mounted projectile targeting coordinates testing system adopts an LED array that is arranged in an approximate arc as a light source (L) and forms a lens-typed light curtain detector (D) by coordinating an optical lens with a rectangular slit diaphragm and a photoelectric receiving device, thus forming a single large light curtain detecting scene (S); six array light sources and the lens-typed light curtain detector are hung on a wall with indoor target lanes and arranged in a certain geometrical shape, and the testing light curtain array is formed in the target lane space. When a projectile runs through the light curtain array, the data collecting and analyzing system collects a projectile targeting signal, and according to a spatial curtain surface equation, the targeting coordinates of the projectile running through the target surface are obtained. The wall-mounted structure of the wall-mounted projectile targeting coordinates testing system with the large target surface has convenient protection, avoids the damage of the target body that is caused by a live firing test, greatly saves the space of the target lane, and can successfully solve the indoor target lane testing problem of heavy-caliber projectiles, exuviates bullets and flame tracers.

Description

technical field [0001] The invention relates to the field of ballistic parameter testing of small and medium-caliber weapons used in indoor target tracks, in particular to a wall-mounted large target surface projectile landing coordinate testing system based on the principle of intersection testing of six light curtains. Background technique [0002] In the production and development of small arms, it is necessary to test the target position and velocity of projectiles. The traditional contact measurement method is to erect plywood or veneer or gauze at the position specified by the ballistic, and measure the position of the bullet hole by hand after shooting. This type of method has disadvantages such as difficulty in target layout, time-consuming measurement, inability to identify heavy holes, inability to give measurement results in real time, and easy to be affected by the environment, so it is gradually replaced by various non-contact automated testing methods.
