本文介绍并分析了日本的X射线天文卫星ASTRO-H中SpaceWire的应用模式,然后结合我国星载数据管理系统建立了SpaceWire总线应用的仿真系统,模拟星载管理单元与设备以及设备与设备间的数据通信,实现了对系统综合数据业务的统一管理,对在轨数据系统实施自主管理和冗余容错管理奠定了技术基础.
This paper described and analyzed the application mode of SpaceWire in ASTRO-H,and then combining China′s onboard data management system,established a simulation system where SpaceWire was used for data communication between onboard management unit and equipments simulated,and achieved unified management of the comprehensive data services,which establishes the technical foundation for the onboard system in self-management and the redundancy and fault-tolerant management.
