摘　　要：为了满足航电系统升级改装过程中集成测试对大量低延时数据交换的需求,设计并实现一种航电中继系统。底层分布式支撑网络由反射内存网技术构建,上层转发逻辑由实时操作系统平台控制,进行大量数据的低延时转发。该系统可将不同类型信号在多种设备之间进行远程异地转发,转发过程能通过多个并发通道低延时中继大量数据。数据转发实验结果表明,航电中继系统中继的数据准确、可靠,系统实际延时为微秒级。In order to meet the needs of large-scale,low-latency data exchange during the upgrade and modification of the avionics system,we design and implement an avionics relay system.The underlying distributed support network of the avionics relay system was constructed by the reflective memory network technology,and the upper layer forwarding logic was controlled by the real-time operating system platform to perform low latency forwarding of a large amount of data.The system can remotely forward a different type of signals between multiple devices,and the forwarding process can relay large amounts of data through multiple concurrent channels with low latency.Data forwarding experimental results indicate that the data relayed by the avionics relay system is accurate and reliable,and the actual system delay is microsecond.
