摘要
近年来,电磁炮成为了世界各国争相研究的新概念武器。其具有许多传统火炮无法比拟的优点和发展潜力,因此针对一种能够自动搜寻目标的低成本简易电磁炮进行研究。该系统以STM32F429为主控芯片,通过OPENMV摄像头获取位置信息,搭载二维电动云台使电磁炮可在一定范围内自由移动,并建立斜抛运动模型来模拟炮弹在空中的运行轨迹,从而计算出抛射仰角及偏角。测试结果表明,当偏角处于中心轴线60°以内时,落点相对误差小于5 cm,可实现对靶心较精准的击中。
Recently,electromagnetic gun has become a new concept weapon in the world.It has many advantages and development potential that the traditional artillery cannot compare with.Therefore,a kind of low-cost and simple electromagnetic gun that can automatically search the target is studied.The system takes STM32 F429 as the main control chip,obtains the position information through the OPENMV camera,carries a two-dimensional electric head to make the electromagnetic gun move freely in a certain range,and establishes the oblique throwing motion model to simulate the trajectory of the projectile in the air,so as to calculate the elevation Angle and deflection Angle of the projectile.The test results show that when the hitting target is within 4.5 m from the launching point and the deflection Angle is within 60°from the central axis,the relative error of the landing point is less than 5 cm,which can achieve a more accurate hitting of the target.
