基于云计算的航天器控制系统自组织体系结构

The Cloud-Computing-Based Self-Organizing Architecture for Spacecraft Control System

针对目前航天器控制系统中计算单元冗余备份过多但系统动态效能不足的问题,提出一种航天器控制系统自组织体系结构,通过高速对等网络将系统建立在云计算的基础上,取消单节点的冗余备份,以系统整体能力为单个节点做备份,当出现节点故障时动态迁移其程序和数据到其他正常节点以继续其功能,从而实现系统在故障时计算体系的动态聚合重构.

A self-organizing architecture for the control system of spacecraft is proposed to solve the prob- lem that the computing efficiency is insufficient for many redundant computing units. Based on cloud computing and high speed interconnected net, the redundant backup of the single node is cancelled in the proposed architecture. The computing capability of whole system is the staunch supporter for every single node. If one node shuts down, its program code and data will be transferred to other working nodes dy- namically to continue its functions. This self-organizing manner realizes the reconstruction of computing architecture for system with faults.
