Research on FC-AE-1553 Bus on Rocket-bornt Test System

现代航天飞行器电子系统的设计已经向着高度综合化和以信息交换为中心的方向发展,同时随着我国航天数据通信系统对光纤总线技术越来越重视,以FC-AE为代表的光纤总线技术已经渗透应用到航天运载火箭、卫星、空间站和导弹武器系统等许多方面。数据通信总线已向着具有更高的信息传输速率、传输容量及适应性以及定向数据分配协议的新型高速数据总线发展,介绍了FC-AE-1553总线的基本特性,并以航天器测量系统为背景,构建总线简单环形拓扑结构,为系统典型设备设计FC-AE-1553总线接口模块,设计航天器系统工作模式和FC-AE-1553总线通信协议,并通过联试模拟航天器系统工作,仿真FC-AE-1553总线主要性能,验证FC-AE-1553总线作为航天器系统骨干总线的适用性。

With the fast development towards the direction of being highly synthesized and information exchanging, and with more attention has been paled to the fiber bus technology in space communication system, FC-AE is broadly applied and developed in the field of avionics measurement system, astronautical rocket, sateUite, aerospace station, space missile and so on. This new high speed data bus has developed towards higher transmission rate, larger capacitance as well as flexibility and directional informa- tion distribution protocol. This paper described the basic characteristics of FC-AE-1553 bus, considering the space vehicle test sys- tem as background, constructed the simple network loop topology, designed FC-AE-1553 bus interface module for special devices, system working principle, and FC-AE-1553 bus transmit protocal. Furthermore, we emulated function index of FC-AE-1553 net- work, verified the bus adaptability as system backbone bus.
