评述新型航空电子系统总线互连技术,探讨其发展趋势。对综合模块化和分布式模块化航空电子系统体系架构的优劣势进行分析,对FC航空总线技术、AFDX总线技术和TTE总线技术的各自特点加以对比。基于TTE总线技术的分布式模块化航空电子平台有助于化解应用冲突,具有更好的实时性、可扩展性和可靠性。相关规范的制定、更为宽泛的网络拓扑结构的引进,将进一步促进其整体性能的提升,使其无疑成为新一代航空电子核心技术。
Comment on the new avionics bus interconnection technology and discuss its development trend. The advantages and disadvantages of the integrated modular and distributed modular avionics system architecture are analyzed, and the respective characteristics of FC aviation bus technology, AFDX bus technology and TTE bus technology are compared. Distributed modular avionics platform based on TTE bus technology helps to resolve application conflicts with better real-time, scalability and reliability. The formulation of relevant norms and the introduction of a more extensive network topology will further promote the overall performance improvement and will undoubtedly become the next generation of avionics core technologies.
