机载总线网络及其发展

A Survey on Avionics Bus and Network Interconnections and Their Progress

从当今机载电子系统对信息传递的需求出发,纵观航空电子综合化系统的发展阶段,说明为了适应新一代航空电子系统的大容量、深层次的信号与信息综合的要求,机载互连手段从较低速率的总线向宽带网络发展成为必然的趋势。介绍了光纤通道(Fiber Channel,FC)、可扩展性一致性接口(Scalable Coherent In- terface,SCI)以及波分复用光网络等宽带互连方案,给出它们的研究动向,说明它们作为先进综合式航空电子系统统一网络(Universal Avionics Network,UAN)的候选所具有的特点。

This survey firstly recalls the developing phases of avionics integrated systems, and then illustrates the inevitable trend of shifting media shared data buses to wideband networks in airborne device/module interconnections in order to respond the next generation avionics system requirements by the large capacity high integrated signal/information interactions. This paper also introduces the Universal Avionics Network （UAN） candidate solutions for the advanced integrated avionics systems, i.e. Fiber Channel （FC）, Scalable Coherent Interface （SCI） and the optical network with wavelength division multiplexing technologies, and addresses their features and research directions.
