摘要
针对AFDX网络在民用飞机综合化航空电子系统中应用,在对AFDX网络协议技术特点分析的基础上,提出了交换机体系架构和端系统体系架构的实施方案。分析了交换机帧过滤、流量警管、帧调度与转发的实现方式,论述了端系统虚拟链路调度、余度管理和协议栈的实施机制。研制了AFDX网络交换机和端系统,并开发了支持网络应用的配置仿真以及数据加载工具,提供了AFDX网络在航电系统应用的全套解决方案。通过AFDX网络测试平台对研制的交换机与端系统产品进行了验证测试,实际测试结果表明,AFDX网络交换机、端系统产品的设计完全符合ARINC664规范设计要求,能够满足高速航空电子网络数据传输的实时性、确定性与可靠性要求。
Aimed at the application of avionics full duplex switched Ethemet （AFDX） to civil aircraft integrated avionics system, on the basis of the analysis of AFDX technology characteristics, the implementary solutions to switch and end system architecture are pro- posed, including switch flame filtering, traffic policing, scheduling and forwarding mechanism, and end system virtual link scheduling, redundancy management, protocol stack implementation method. The practical AFDX switch and end system products are developed, and the corresponding configuration, simulation and data load tools are designed simultaneously, which provide a complete solution to AFDX network implementation. According to the functionality and performance test on the AFDX network test platform, the results show that the designed AFDX network switch and end system products fully satisfy the ARINC 664 standard and meet real-time, deter- minate and reliable data transmission demands of the high-speed avionics network.
