基于GIS技术与半定性推理的导弹测试电路故障诊断

The Fault Diagnosis of Missile Test Circuit Based on GIS and Semi-qualitative Techniques

研究了利用GIS与半定性推理技术进行导弹测试电路故障诊断的方法。首先利用GIS技术提取测试电路关键特征线路及器件信息,然后构建电路模型和状态模型,最后根据故障现象应用模糊-定性方法进行故障点分析。实践表明该方法形象化了故障分析过程,提高了导弹测试电路仿真与故障诊断的效率。

This fault diagnostic techniques of missile test circuit using GIS and semi-qualitative reasoning techniques was studied. Firstly, the key information of circuitry and component was extracted using GIS technology, and then the circuitry model and status model were constructed. Finally the Fuzzy-qualitative based fault diagnosis was used to analysis fault point based on the fault phenomenon. In this way, the process of fault analysis was visualized and the efficiency of circuit simulation and fault diagnosis is greatly improved.
