摘要:
针对深空探测过程中资源严重受限(包括计算资源、硬件资源以及能量资源)和不可维修的特点,开展了深空探测器可重构性综合评价方法和自主重构的研究。通过在地面设计阶段考虑深空探测器控制系统的可重构性,定量地给出了系统可重构性综合评价指标,并基于该指标指导系统自主重构策略的设计,从设计角度提高了深空探测器控制系统运行质量,实现了深空探测器的自主故障处理和自主运行。

Abstract:
In view of the severely limitation of resources (including computing resources, hardware resources and energy resources) and unmaintainable characteristics in the process of deep space exploration,the comprehensive evaluation method and autonomous reconfigurable strategy of deep space probes are studied. In this paper,the reconfigurability of the deep space probe control system is considered in the ground design stage, and the quantitative comprehensive evaluation index of the system reconfigurability is given.
The autonomous reconfigurable strategy is given based on the proposed evaluation index,which improves the operation of the control system of the deep space probe from the perspective of design and achieves the goal of autonomous fault handling and autonomous operation of deep space probes.
Key words:  deep space probes;reconfigurability evaluation methods;autonomous reconfigurable strategy
