针对激光光幕法测试弹丸坐标时需要采集多路光电信号的问题，提出了以FPGA为采集及控制芯片，以FLASH为存储芯片的多路光电信号采集与存储系统的设计。通过将采集到的光电信号缓存在FPGA内建FIFO中，然后对该信号进行处理并存储在FLASH中，使用USB接口与上位机进行通信传输。仿真结果表明，该系统可成功将64路光电信号采集并存储，结构灵活、操作简单，数据准确且存储量大。
針對激光光幕法測試彈汍坐標時需要採集多路光電信號的問題，提齣瞭以FPGA為採集及控製芯片，以FLASH為存儲芯片的多路光電信號採集與存儲繫統的設計。通過將採集到的光電信號緩存在FPGA內建FIFO中，然後對該信號進行處理併存儲在FLASH中，使用USB接口與上位機進行通信傳輸。倣真結果錶明，該繫統可成功將64路光電信號採集併存儲，結構靈活、操作簡單，數據準確且存儲量大。

In the view of the problem on the measurement of projectile coordinate based on laser screen that needs massive optical signals, the design of massive optical signals acquisition and storage system is proposed. FP-GA is used as the chip of acquisition and control and FLASH is used as the chip of storage. The collected photoelec-tric signals are temporarily placed in the FPGA build-in FIFO, and then these signals are processed in the FPGA and stored in the FLASH, and USB interface is used to communicate with computer. The simulation results show that the system could collect and store 64 digital signals successfully, it has flexible structure, simple operation, ac-curate data and large storage.
