摘　　要：针对目前高速自动炮运动特性仿真结果经常与实际情况存在较大差距的问题,提出一种基于惯性传感器的嵌入式测量存储系统。利用惯性器件采集到的模拟信号经A/D转换芯片和具有并行处理能力的现场可编程门阵列(field-programmable gate array,FPGA)芯片进行多路信号的采集存储至NAND FLASH,测试完毕后通过上位机进行读取分析。试验结果表明:该系统能还原弹丸运动特性,具有较高的稳定性和测量精度,为缩短高速自动炮研发周期提供数据支持。Aiming at the problem that the simulation results of high speed automatic gun are often different from the actual situation,an embedded measurement and storage system based on inertial sensor is proposed.The analog signal collected by the inertial device is stored in the NAND FLASH by the AD conversion chip and the Field Programmable Gate Array(FPGA)chip with parallel processing capability.After the test,through the host computer to read and analysis.The experimental results show that the system can restore the motion characteristics of the projectile and has high stability and measurement precision,which can provide data to shorten the development cycle of high speed automatic gun.
