Embodiment 1

[0068] Embodiment 1: see figure 1 and Figure 5 , the method for measuring the flight speed and target coordinates of the double-barreled salvo weapon projectile of the present invention

[0069] When the projectile of the double-barreled salvo weapon flies through the eight-screen test light curtain array, the detection device outputs a corresponding electrical signal, and the eight-way data acquisition device accurately acquires this electrical signal, so as to obtain the time when the projectile passes through the eight light curtains in sequence, and the data It is transmitted to the host computer at the gun position through wireless data transmission equipment. The host computer identifies the flying projectile through the calculation algorithm of speed and target coordinates, stores and displays the flight speed of the projectile and the position coordinates when passing through the target surface. The specific process is as follows:

[0070] one. The geometric struct...

Embodiment 2

[0088] Embodiment 2: implementation method is the same as embodiment 1

[0089] For the measurement of a single projectile, by the surface linear equations in the embodiment 1 step (three) Known, unknown parameters are required , you need to know 6 irrelevant screen surface linear equations, usually four light curtain detection devices , In the generated light curtains, 3 screens are selected respectively, so there are A combination of tests:

[0090]

[0091] 16 test combinations for linear equations full rank, we can get , that is, the flight speed of the projectile and the position coordinates when passing through the target surface can be obtained, and the azimuth and pitch angle of the projectile when flying can also be obtained.

Embodiment 3

[0092] Embodiment 3: implementation method is the same as embodiment 1

[0093] For the measurement of two projectiles, there are 15 cross-screen signals collected by the eight-way data acquisition device as an example:

[0094] 1. Let the velocity of projectile 1 be , reaching the curtain The coordinates are , the velocity of projectile 2 is , reaching the curtain The coordinates are , assuming that projectiles 1 and 2 arrive "only" at the same time , and the time is the "0" time reference point, and the measured projectile 1 reaches the curtain The moments are , Projectile 2 arrives at the curtain The moments are , . Arranging and combining the measured moments, there are a total of combination of moments:

[0095]

[0096]

[0097] For these 128 time combinations, including the real time of each projectile 1 and 2 , .

[0098] 2. Set corresponding decision-making rule algorithm: with 16 kinds of test combinations of embodiment 2 Me...

Abstract

The invention discloses a method and a device for realizing measurement of a flying speed and a landing coordinate of a projectile of a double-tube volley weapon for outdoor target lanes. The method comprises the following steps that: eight test light curtain arrays are arranged along a trajectory direction; when the projectile flies through the light curtain arrays, a detecting device generates corresponding electric signals so that eight paths of data acquisition devices acquire curtain-passing signals accurately, and transmit the signals to an upper computer through wireless digital transmission equipment; and the upper computer recognizes the flying projectile through a speed and landing coordinate calculation algorithm, stores and displays the flying speed of the projectile and the position coordinate on the surface of the target. The method is simple in theory and easy to realize. The measurement device provided by the invention comprises the detecting device, the data acquisition devices, the wireless digital transmission equipment, the upper computer, a memory and a display; and the detecting device consists of two four-light-curtain detecting devices. The device has a simple structure and low cost, and can realize quick and precise measurement of trajectory parameters of double-tube or single-tube volley weapons under the large-scattering condition of the trajectory at the end point.

Description

technical field [0001] The invention belongs to the technical field of shooting range testing, and mainly relates to a method for measuring the flight speed and target coordinates of projectiles of various calibers and large-spread double-tube salvo weapons used in outdoor target tracks, and particularly relates to a method based on the intersection of eight light curtains. A dual-objective multi-ballistic parameter measurement device based on the measurement principle. Background technique [0002] Projectile velocity and shooting intensity are one of the main technical indicators measured by guns, cannons, and projectile manufacturers in product inspection, and the basis for measuring shooting intensity is the measurement of projectile target coordinates. Replacing the traditional measurement methods such as wooden target and gauze target with backward technology, low efficiency and poor precision, the automatic measurement of projectile target coordinates has always been ...
