Parameter testing system and method for high-speed moving object

Abstract

The invention discloses a parameter testing system and a parameter testing method for a high-speed moving object. The system mainly comprises a starting target, a stopping target, a data acquisition module, a master control module and a data transmission processing module, wherein each of the starting target and the stopping target consists of an X-axis and Y-axis rectangular laser light curtain emission unit, an X-axis and Y-axis photosensitive tube array and an amplification shaping unit; the starting target and the stopping target form two parallel virtual thin light curtain target surface which are at a determined interval; the data acquisition module consists of a plurality of field programmable logic arrays (FPGA) with built-in first in first out (FIFO) buffer memories; the master control module consists of an FPGA and a memory FLASH; and the data transmission processing module comprises a universal serial bus (USB) data interface and an upper computer. According to the system, the output level state of the X-axis and Y-axis photosensitive tube array at each moment when the object flies through thin light curtain areas is acquired and stored at high speed under the control of the FPGA of the master control module, and the speed of a fragment, landing coordinates and an overall dimension are calculated by data processing.

Description

technical field [0001] The invention belongs to the technical field of testing, and in particular relates to a high-speed moving target parameter testing system and method. Background technique [0002] The high-speed moving target in the present invention mainly refers to conventional projectiles, fragments produced by the explosion of warheads, explosively shaped projectiles (EFP), etc. For testing the speed of high-speed moving targets, the existing methods often use devices such as laser targets, LED bright targets, sky screen targets, coil targets, and mesh targets. Object size function; for the coordinates of high-speed moving targets, the method of line array CCD (or CMOS) camera intersection test is often used, and the method of light curtain intersection is also used, but the general system is complex and does not have the ability to test the speed and shape of the measured target and other functions.
