Design of High-speed Intelligent Storage Technology Based on Gigabit Ethernet

为了准确、完整地记录导弹在发射与飞行过程中的各种状态参数,并且对存储数据进行高速回收处理,设计了一种基于千兆以太网的高速智能存储系统。该系统以FPGA为控制中心,将PCM数据码流接收后经过编码解析存入Flash,最后通过千兆以太网、RS422多模式接口将数据快速回传至上位机显示。经试验验证,该智能存储系统具有传输速率高、抗干扰能力强、可靠性高等特点,能够满足弹载数据存储测试的要求,目前已成功应用于某弹射试验弹弹载数据测试中。

In order to accurately and completely record various state parameters of missiles during launch and flight,and recycle the stored data at high speed,a high-speed intelligent storage system based on Gigabit Ethernet is designed.The system takes FPGA as the control center,after receiving PCM data stream,it is encoded and parsed and stored in Flash.Finally,the data is quickly read and sent back to the upper computer for display through Gigabit Ethernet and RS422 multi-mode interface.The experiment results show that the intelligent storage system has the characteristics of fast transmission rate,strong anti-interference ability and high reliability,and can meet the requirements of missile-borne data storage and testing.At present,it has been successfully applied to the missile-borne data testing of an ejection test.
