摘　　要：综合化航空电子系统对总线网络的传输速率和确定性提出了较高要求。针对普通光纤通道总线存在确定性差的问题,提出了一种时间触发光纤通道总线的设计与实现方案,采用主从方式实现网络时间同步,以及多缓存时间触发传输结构。详细阐述了节点的现场可编程门阵列逻辑设计实现方案,并在样机平台上进行了实物测试与验证。所提出的基于光纤通道的时间触发传输方案仅需对节点协议进行适应性修改,可应用于综合化的航空电子系统。The integrated avionics system puts forward higher requirements for the transmission rate and determinacy of bus network.To solve the poor determinacy of ordinary fibre channel(FC),this paper proposes a design and implementation scheme for the time-triggered fibre channel,which uses the master-slave method to realize the network time synchronization,and the multi-buffer time-triggered transmission structure.The field programmable gate array(FPGA)logic design and implementation scheme of the node are described in detail.Tests have been done to show the correctness of the proposed method on prototype platform.The proposed time-triggered transmission scheme based on fibre channel needs little change to the protocol adaptively,which can be used in the integrated avionics system.
