摘　　要：针对触发式瞬态信号存储测试系统的不足,基于FPGA设计了连续采集模式的大容量瞬态信号存储测试系统,由FPGA控制高速AD转换芯片对12路冲击加速度信号进行连续同步采集,最高采样频率为100kHz,并实时将采集到的数据连续存储到大容量FLASH;系统内部集成网络接口芯片,上位机可以通过RJ45接口快速读取测试系统中存储的数据;测试系统在水平碰撞试验中进行了应用,通过试验验证了系统的有效性。In view of the shortage of the trigger mode impulse signal measurement system,a continuous acquisition mode flash storage impulse signal measurement system is designed based on FPGA.The FPGA controls the 12 channel high-speed AD chip to collect shock signal continuously,and the maximum sampling frequency can reach to 100kHz.The collected data are stored in NAND FLASH in real time continuously.The upper computer can quickly read the data stored in the NAND FLASH through RJ45 port with a network interface chip embed in measurement system.The measurement system is applied in the horizontal collision test,and the effectiveness of the system is verified.
