在诸如深空、深海等特殊环境中的电子电路,传统的基于冗余容错技术提高电子系统可靠性的方法受到了很大程度的限制,进而基于硬件演化(EHW)的故障自修复策略开始被广泛研究。但是后者也存在一些弊端,如存在电路演化规模大、电路演化速度慢、故障修复能力有限等问题。因此,在前期工作中,提出了基于EHW和补偿平衡技术(RBT)的电路故障自修复策略。通过从故障自修复能力、故障修复速度、硬件资源消耗等角度对比分析,相比于常规的基于EHW的故障自修复策略,基于EHW和RBT的电路故障自修复策略的故障修复方法灵活、故障修复类型多,且能缩减电路演化规模、缩短电路演化时间、提高电路修复速度、硬件资源消耗可控,其可行性和有效性得到了论证,具有重要的工程应用价值。
In electronic circuits such as deep space, deep sea and other special environments, the traditional method of improving the reliability of electronic systems based on redundant fault-tolerant technology has been greatly limited, and then the fault self-healing strategy based on hardware evolution (EHW) Extensive research. However, the latter also has some drawbacks, such as the existence of large-scale circuit evolution, circuit evolution slow, fault repair capability is limited and so on. Therefore, in the previous work, a circuit fault self-healing strategy based on EHW and compensation balance technique (RBT) was proposed. Compared with the conventional EHW-based fault self-healing strategy, the fault self-healing strategy based on EHW and RBT is flexible and the fault is repaired through the comparison and analysis from the perspectives of fault self-healing capability, fault recovery speed and hardware resource consumption. And can reduce the circuit evolution scale, shorten the circuit evolution time, improve the circuit repair speed, and control the hardware resource consumption. The feasibility and effectiveness of the circuit have been proved, which has important engineering application value.
