Real-time measurement method for quantity of shot bullets of small arm

Abstract

The invention relates to a real-time measurement method for automatically measuring quality of actually shot bullets when a small arm in stillness or motion shoots at a target. The method includes: aiming for each bullet, arranging an acoustic transducer at the lower position of a muzzle to collect a bullet shockwave signal and a muzzle shockwave signal, selecting a specific time difference between the bullet shockwave signal and the muzzle shockwave signal received by the acoustic transducer, and calculating the quantity of the actually shot bullets with a mathematical model. The method is free of influences of bullet shape and structure parameters as well as optical, magnetic, electrical and acoustic interferences, high in measurement accuracy and convenient to use, and calibration coefficients are not required. The high-accuracy measurement method is provided for measuring the quantity of the actually shot bullets automatically in real time when the small arm shots at the target.

Description

technical field [0001] The invention relates to a method for automatically and real-time detection of the number of actually fired bullets when a static or moving light weapon shoots at a target. Background technique [0002] The whole process of development, production, use and maintenance of light weapons equipment requires live ammunition shooting tests, and it is necessary to know the actual number of bullets fired. Departments using light weapons such as the army, armed police, and public security also need to conduct real-time detection of the number of bullets used. Carry out scientific management. In existing foreign relevant literature, also do not see the open technical report of the test method of automatic, real-time detection actual shot bullet quantity when the light weapon in relevant stationary or motion shoots to the target. National Defense Patent No. 02101297.0 discloses a method and equipment for testing the deviation distance (r) of the nearest projecti...

Problems solved by technology

National Defense Patent No. 02101297.0 discloses a method and equipment for testing the deviation distance (r) of the nearest projectile distance (r) between the projectile and the target aiming center when multiple guns of different calibers shoot at the air at the same time. Acoustic detection method is mainly used for the projectile deviation test of artillery shooting to the air. Although this method and equipment can also detect the actual number of projectiles fired, its cost is high and the equipment is large, so it cannot be carried with light weapons; In addition, the method of detecting the actual number of bullets fired by light weapons at the target also needs to prevent the interference of the external environment, such as: external collisions, interference from light, magnetism, electricity, and sound, so the measurement of the above-mentioned existing methods cannot meet the requirements of light weapons to target Requirements for measuring the actual number of bullets fired when shooting at a target
