摘　　要：随着航天控制系统性能的不断提升,为验证基于以太网接口的测量单元在5G局域网内通信的可靠性,设计了一种基于ZYNQ的数据传输系统。该数据传输系统具备2路千兆以太网接口,分别连接测量单元和5G交换机,以完成测量单元和5G交换机之间的双向数据透传。同时,配备嵌入式多媒体卡(embedded Multi Media Card,eMMC)作为固态存储单元,系统可依照控制指令对测量单元发送的数据帧进行记录与回读,用于供系统进行可靠性验证。系统中2路千兆以太网接口的数据传输利用Lightweight IP(LwIP)协议栈完成。经验证,该数据传输系统具备双向数据传输、数据记录及数据回读能力,为基于ZYNQ的以太网数据传输和数据记录提供了一种可靠的实现方案。With the improvement of aerospace control system performance,a data transmission system based on ZYNQ is designed to verify the communication reliability of the ethernet interface measuring unit in 5G LAN.In the system,there are two gigabit ethernet interfaces,which are connected to the measuring unit and the 5G switch respectively,in order to complete the bidirectional data transparent transmission between the measuring unit and the 5G switch.At the same time,embedded Multi Media Card(eMMC)is used as the solid-state storage unit.The recording and reading back of the data frames sent by the measurement unit can be conducted by the system according to the control instructions,so as to verify the system reliability.LwIP is used to enable the data transmission of the two gigabit ethernet interfaces.The experiment results show that the data transmission system can realize the bidirectional data transparent transmission,data storage and date read-back,providing a reliable implementation solution for gigabit ethernet data transmission and data recording based on ZYNQ.
