为满足舰用指挥控制系统大批量数据传输及实时性的应用需求,设计一种千兆以太网高速数据传输系统。系统采用现场可编程门阵列(FPGA)为主控芯片、88E1111为物理层网卡芯片,以满足舰用指控系统多通道、大数据、实时的高速传输要求。实验结果表明,系统以太网传输速度达到926 Mbit/s,有效解决了舰艇指控系统多通道大数据实时传输的问题,具有较大的应用前景。
In order to meet the requirements of mass data transmission and real-time applications of ship’s command and control system, a Gigabit Ethernet high-speed data transmission system is designed. System uses field programmable gate array (FPGA) as the master chip, 88E1111 physical layer network card chip to meet the multi-channel, big data, real-time high-speed transmission requirements of the ship accusation system. Experimental results show that the system Ethernet transmission speed reaches 926 Mbit / s, which effectively solves the problem of real-time transmission of multi-channel big data of the ship accused system and has a great application prospect.
