基于知识推理的航天器自主故障诊断方法

面向深空探测这类型号任务,提出一种基于知识推理的航天器自主故障诊断的智能方法,采取直接线性存储的知识库结构、主动监测事实更新并触发推理以及基于散列算法的事实管理三项关键技术,适用于航天器硬件处理能力和存储容量受限的应用环境.采用C语言在基于TSC695处理器的嵌入式系统上实现了该故障诊断方法,实验的结果表明该方法有效.

Knowledge Inference Based Self Fault Diagnosis Method for Spacecraft

Aiming at missions such as deep space exploration,an intelligent self-fault diagnosis method based on knowledge inference is presented for spacecrafts in this paper.Three key techniques,knowledge base structure with direct linear storage,active monitoring-based fact updating and triggering reasoning,and hash algorithm based fact management are adopted.These key techniques are fit for spacecraft's hardware with limited processing capability and memory capacity in space application.In this paper,the fault dia...
