Multi-channel data acquiring device for measuring fragment group target landing position and target landing time

Abstract

The invention belongs to the technical field of power parameter testing of killing warhead fragment groups, in particular relates to a multi-channel data acquiring device for measuring fragment grouptarget landing position and target landing time. The multi-channel data acquiring device comprises a single-chip microcomputer master-slave communication system, a comb-shaped target and a computer, wherein the single-chip microcomputer master-slave communication system is formed by connecting a master machine and a plurality of slave machines, fragment target landing signals collected by the slave machines are sent to the master machine in one time, and then the master machine sends the signals to the computer. According to the multi-channel data acquiring device for measuring the fragment group target landing position and target landing time, the fragment target landing signals can be converted into corresponding I / O port level signals, and information of target landing positions and corresponding target landing time of fragments can be discerned; and the multi-channel data acquiring device is used for measuring the information of the target landing position and the corresponding target landing time of the fragment group so that the test cost can be reduced. The multi-channel data acquiring device is small in size, simple in structure and capable of improving test convenience.

Description

technical field [0001] The invention belongs to the technical field of testing the power parameters of a fragment group of a killing warhead, and in particular relates to a multi-channel data acquisition device for measuring the target position and time of the fragment group. Background technique [0002] There are various methods for measuring the flying speed of fragments, from the initial tandem mesh target method and aluminum foil method, to the later high-speed photography method, comb target method, and then to the light curtain target method, the test methods are more and more advanced, and for specific Subjects have developed specialized test methods. [0003] The tandem mesh target method and the aluminum foil method can only measure the landing time of a single projectile or the fragment that first reaches the target plate, which is far from enough for constructing the explosive fragment power field of the warhead. Wang Gao et al. improved the series net target to...
