摘要
采用双机冗余的容错方案,对小卫星星务管理计算机容错系统的设计进行了较为深入的探索。在设计中,充分利用软、硬件容错技术相结合的优势,完成了星务管理计算机系统级和部件级硬件体系结构设计。提出了在主机发生故障的临界状态,启动备份机工作的临界切换设想。最后,通过仿真实验和系统模型可靠性分析,证明了系统可以满足设计的要求,具有较高的理论和实践价值。
Using dual redundant fault tolerant program, a small satellite management computer fault tolerant system is designed. Makeing full use of software and hardware fault tolerant advantages, the design of management system level and component level are completed. An avenue about backup computer start is presented when main computer in failure. The simulation results confirm that system has well performance.
