摘要
为了实现FC-AE-1553和MIL-STD-1553两种总线网络之间信息单元的准确传输,分析了当前航电系统的应用现状,描述了FC-AE-1553协议在总线应用方面的性能优势,提出了两种协议之间的转换方案,实现了两种信息单元格式之间的转换。在FC-AE-1553帧与MIL-STD-1553字相互映射关系的基础上,对协议转换方案进行了总体分析,并按照子功能进行了模块的划分。针对各个子模块,依据其运行机理给出了详细的设计流程。仿真分析结果表明,协议转换方案具有良好实时性能,具有很强的适应性。
In order to realize the correct transforming of information elements between bus network FC-AE-1553 and MIL-STD- 1553, the current application situation of avionics system is firstly analyzed, and then performance advantages of FC-AE-1553 protocol are described in bus application. The transforming scheme between two protocols is brought forward, which realizes the transforming of two information elements＇ formats. On the basis of the mutual mapping relation between FC-AE-1553 frames and MIL-STD-1553 words, the transforming scheme is analyzed in the mass, and modules are carved up in the light of their func- tions. The detailed designing procedures are shown according to their operation mechanism. The results of simulation analysis in- dicates that the protocol-transforming scheme possess fine real-time performance and has powerful adaptability.
