摘　　要：红外探测系统逐渐采用更大面阵、更快频次的焦平面探测器对红外信号进行探测,因此系统数据量呈指数式增加。为此,设计了万兆以太网高速数据传输方案,以FPGA为主控核心芯片,对数据传输链路进行了搭建,采用UDP协议实现数据的高速传输,传输模块采用AXI4-Stream协议进行通信。在红外探测系统中对传输方案进行了测试与验证,系统数据传输速度可达9.7 Gbps,满足系统数据传输需求。对大数据量传输验证,无数据丢点出错的情况出现,表明传输方案的可靠性,具有实际的工程应用价值。The infrared detection system gradually adopts the focal plane detector with larger surface array and faster frequency to detect the infrared signal,so the system data volume increases exponentially.Based on this,a 10 Gigabit Ethernet high-speed data transmission scheme is designed,with FPGA as the main control core chip,the data transmission link is constructed,the UDP protocol is used to realize high-speed data transmission,and the transmission module adopts the AXI4-Stream protocol for communication.The transmission scheme is tested and verified in the infrared detection system,and the system data transmission speed can reach 9.7 Gbps,which meets the system data transmission requirements.For the large data volume transmission verification,no data loss point error occurs,indicating the reliability of the transmission scheme,has practical application value.
