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.
