一种双光幕弹丸测速系统设计与实现
A Dual-Light Screen Bullet Velocity Measuring System Design and Implementation
摘要
Abstract
In modern weapons research,high precision measurement of bullet velocity is indispensable,a Dual-Light Screen Velocity Measurement System(LSVMS)was designed which is composed of hardware and software. The system takes FPGA as the control core,implementing the conditioning and acquisition of current signal from front light screen sensor by controling hardware circuit,then the data will be stored and uploaded to the host com⁃puter through the network port. The design adjusts the signal to zero by software,which solves the problems of insta⁃bility of adjusting to zero by traditional hardware and uses way of bomb bottom trigger to timing,which improves the accuracy of the velocity of the bullet. Compared with the traditional velocity measurement system ,the system is more accurate and more flexible. After several tests and experiments,the system has been successfully applied to the development of a military product.关键词
