摘　　要：针对高旋弹数据分析与存储的实时性、小空间、低功耗、大容量要求,设计适用于高旋弹用实时数据处理与存储系统;并提出一种数据处理与存储方法,实现了常规炮弹在飞行过程中的传感器数据实时处理与获取。首先针对高旋弹工作环境与数据采集过程进行分析,确定数据处理与存储需求;结合需求,利用Cortex-M7与FPGA的双核心架构配以外部并行高速ADC,实现传感器信号的采集与处理,利用高速FMC总线控制大容量片外FLASH,实现处理数据的存储,在此硬件基础上,提出了同步高速数据采集与存储方法。通过高速转台地面试验和实弹飞行验证了系统功能的正确性,其对常规炮弹弹道环境力以及制导化研究具有很大的应用价值。In allusion to the requirements of real-time performance,small space,low power consumption,and large capacity of high-spinning projectile data processing and storage,a real-time data processing and storage system applicable for the highspinning projectile is designed,and a data processing and storage method is proposed,so as to realize real-time processing and acquisition for sensor data of the conventional cannonball during flight. The working environment and data acquisition process of the high-spinning projectile are analyzed to determine the data processing and storage requirements. In combination with the requirements,the dual core architecture of Cortex-M7 and FPGA equipped with the external parallel high-speed ADC is adopted to realize the acquisition and processing of sensor signals,and the large-capacity chip external Flash controlled by the highspeed FMC bus is adopted to realize the storage of processed data. On the basis of the above hardware,the synchronous highspeed data acquisition and storage method is put forward. The correctness of the system function was verified by means of the ground test of the high-speed rotary table and live ammunition flight,which has a great application value for the research of ballistic environmental force and guidenization of the conventional cannonball.
