为了使对地压制类弹药引信进一步提升炸点控制能力,以提升毁伤效能,基于射击迹线法和毁伤元特征参数,重构了战斗部威力场,结合对地杀爆类弹药打击目标的特点,给出了毁伤表征方法,定义了引信控制毁伤下降率,详细分析了一种榴弹打击有生力量时的引信炸点控制对毁伤效能的影响规律,并基于引信控制毁伤下降率,获得了最佳炸高和最佳炸高区间。研究发现,引信的炸点控制对弹药的毁伤效能具有显著影响,不同的落速、落角拥有不同的最佳炸高。以一种榴弹为例,引信炸高(1 m)偏离最佳炸高(7 m)时毁伤下降率可高达29%以上,且落角越大毁伤下降率越明显,即炸点控制对毁伤效能影响越显著。

目前,在青霉素工业生产中,人工检测是青霉素结晶状态以及发酵液高度检测的主要方式,这种方式成本高、自动化水平低且易造成误判,对青霉素产量和品质有很大影响。针对此种情况,文中设计了一种基于AMP架构的青霉素结晶状态与发酵液高度检测系统。该系统以ZYNQ-7000作为可重构嵌入式平台。在PL部分,利用Vivado HLS工具实现结晶状态、发酵液高度检测的图像预处理算法IP核设计,并搭建出视觉传感系统的硬件平台。在PS部分,系统采用双核AMP(非对称多处理)运行模式,完成结晶状态检测、发酵液高度检测算法处理与以太网视频传输、图像存储功能的并行处理。实验结果表明:该系统支持2种检测模式的切换,可实现对工业生产中青霉素结晶状态与发酵液高度的精确检测与视频数据的实时传输。
