摘　　要：随着存储设备的高速发展,智能化、高速化、小型化成为不断突破的技术核心。通过增加文件管理模式,设计了高速存储系统。为提高数据传输带宽,使用以太网接口,同时接收多路数据。为保证存储模块重新上电之后可以继续存储通过实时更新存储的操作地址。数据读取时,使用高速串口,提高读出速度。测试结果表明,Flash阵列的数据写入速度为75 Mbyte/s。上位机读取速度为384 Mbit/s,将存储的文件以data文件读出。可见系统准确性高、实用性强,且设备趋向小型化发展。With the rapid development of storage equipment,intelligent,high-speed and miniaturization were break-through core technology.By adding the file management mode,the high speed storage system was designed.To improve the data transmission bandwidth,the Ethernet interface was used to receive multi-channel data in the meantime.In order to ensure that the storage module can continue to be stored after recharging,the operation address of the storage can be updated in real time.When reading data,using high speed serial port improved reading speed.The results show thatthe data write speed of single flash is 75 Mbyte/s.The reading speed of the upper computer is 384 Mbit/s,and the stored file is read out to the data file.It is concluded that the system is of high accuracy and practicability,and the equipment tends to be miniaturized.
