一种航炮运动参数采集系统

为获取某航炮供弹系统的运动学参数，设计一款基于现场可编程门阵列(field programmable gate array，FPGA)和FLASH的运动感知系统。以FPGA为主控芯片，控制多路A/D采集模块实现对三轴加速度传感器的实时数据采集，采集数据写入FLASH存储单元；实验结束后回收采集系统，通过上位机软件对FLASH中数据进行回读，并进行采集系统标定实验，验证系统误差小于3%。射击试验结果表明：该系统能够完整地记录航炮运动参数，满足可靠性和完整性的要求。

Aircraft Gun Motion Parameter Acquisition System

In order to obtain the kinematics parameters of the certain type aircraft gun feeding system, a motion perception system based on field programmable gate array (FPGA) and FLASH is designed. FPGA is used as the main control chip to control the multi-channel A/D acquisition module to realize the real-time data acquisition of the three-axis acceleration sensor, and the acquired data is written into the FLASH storage unit; after the experiment, the acquisition system is recovered, and the data in FLASH is read back by the host computer software, and then the acquisition system calibration experiment is carried out to verify that the system error is less than 3%. The firing test results show that the system can completely record the motion parameters of the aircraft gun and meet the requirements of reliability and integrity.
