基于硬件演化的电路故障自修复实验系统设计与实现

面对复杂的环境,电路系统容易出现故障,且常规电路系统主要基于冗余容错技术提高系统的可靠性。在前期工作中提出了基于硬件演化(evolvable hardware, EHW)和补偿平衡技术(reparation balance technology, RBT)的故障自修复策略,其能够充分利用仿生原理,使电路系统具备自适应、自组织能力。设计实现了能够用于验证所提修复策略的实验系统,并选取了典型电路对基于EHW和RBT的故障自修复策略进行了实验验证,对设计具有自修复能力的电路系统具有重要的指导意义。

Design and implementation of circuit fault self-repair experiment system based on Evolvable Hardware

In the face of complex environment, the circuit system is prone to failure, and the conventional circuit system is mainly based on redundant fault-tolerant technology to improve the system reliability. In the previous work, a novel fault self-repair strategy based on evolvable hardware (EHW) and reparation balance technology (RBT) was proposed, which can make full use of the bionic theory. It makes the circuit system has the ability of self - adaptation and self - organization. In this paper, an experimental system was designed and implemented which can be used to verify the proposed repair strategy, and selected typical circuits for the experimental verification of the fault self-repair strategy based on EHW and RBT. It has important guiding significance for the design of the circuit system with self-repair ability.
