摘要： 针对目前国内外星载系统软件可重构性较差的问题,提出了一种基于软件总线的星载系统软件结构。首先，介绍了软件总线和软构件的结构。其次，阐述了星载实时多任务操作系统中混合任务调度算法的设计。最后，对这个混合任务调度算法的正确性给出了证明。

Abstract: This paper proposes a structure of on-board system software based on software bus, for the poor reconfiguration of on-board system software at home and board at present. Firstly, the structure of software bus and configuration is introduced.Secondly, the algorithm in the real-time multi-tasks operation system is designed.Finally,the correctness proof of the periodic and aperiodic taskscheduling algorithm is given.
