星载FC-SE光总线体系结构及吞吐量研究

Research on the Architecture and Throughput of FC-SE Optical Data Bus

介绍了航空光纤总线FC-AE总线等总线特点及应用现状,分析了星载CAN总线、MIL-STD-1553B总线等数据总线特点及发展需求。基于FC-AE总线,研究了一种兼容MIL-STD-1553B总线的星载FC-SE光总线技术方案、体系结构、协议特点及服务类别,分析了星载FC-SE光总线方案的吞吐量性能。星载FC-SE光总线既可以充分发挥光总线的宽带宽优势,又可以充分兼容现有MIL-STD-1553B低速总线,有效满足卫星载荷多业务、多速率总线技术发展需求。

In this paper, the developing requirement and characteristics of satellite data bus are analyzed. The development,application and prospect of data bus such as MIL-STD-1553B and FC-AE are introduced. Based on the data bus FCAE, a new optical data bus FC-SE for satellite which is compatible with MIL-STD-1553B is introduced. And the architecture, protocol characteristics, and service are studied. The data bus FC-SE can process high data with optical wide band, and also process low data with MIL-STD-1553B. The FC-SE data bus satisfies multi-data and multi-service requirements of the satellite data bus.
