Autonomous projectile initial-velocity measuring device and distance determining system

Abstract

The invention belongs to the technical field of weapon equipment testing, and provides an autonomous projectile initial-velocity measuring device and distance determining system which comprises a muzzle cylinder, a first magnetic element, a second magnetic element, a magnetic induction device and a main control module, wherein the first magnetic element and the second magnetic element are both arranged on the muzzle cylinder; the radial spacing of the muzzle cylinder is regarded as a preset distance; the magnetic induction device and the main control module are both arranged in a projectile; the input end of the main control module is connected with the magnetic induction device; the magnetic induction device is used for detecting the variation of a surrounding magnetic field and sending a magnetic field variation signal obtained from the detecting process to the main control module; and the main control module is used for determining the initial velocity of the projectile according to the magnetic field variation signal and the preset distance. Through the magnetic induction device arranged on the projectile, the variation of the magnetic field can be detected; the own velocity of the projectile can be autonomously determined according to the variation of the magnetic field; the influence of an external environment is little; the velocity measuring accuracy is high; the accurate distance determining effect can be achieved; and the accurate control of a blasting point is facilitated.

Description

technical field [0001] The invention belongs to the technical field of weapon equipment testing, and in particular relates to an autonomous projectile muzzle velocity measuring device and a distance-fixing system. Background technique [0002] With the requirement of precise and rapid strike in modern warfare, the precise distance control of projectile blast point has become an important research topic at present, and the muzzle velocity of the projectile is an important parameter affecting the precision of distance determination. [0003] In the prior art, the muzzle velocity is usually measured by methods such as the radar speed measurement method and the interception device speed measurement method. These methods are external measurement methods, which are easily disturbed by the external environment, and the measurement results are not accurate enough to make accurate distance determination. Affects the precise control of the explosion point. Contents of the invention ...
