摘要 针对惯性导航等航海装备的复杂性,提出了基于故障树和基于案例的故障诊断方法,分析了2种方法各自的优缺点,最后提出将两者相结合的故障诊断方法,充分发挥各自优势,建立案例库,通过学习机对案例进行解释,依据故障树方法建立规则,由推理机调用相关规则进行故障判断. In view of the complexity of the fault in nautical equipment such as inertial navigator, the two fault diagnosis methods which are respectively based on fault tree and case analysis were presented. The advantage and disadvantage of these two methods were analyzed. In the end the fault diagnosis method combining the above two methods was introduced, taking full advantage of the two methods. The case library was established and explained through the learning machine, and the rules were given in the light of the arithmetic of fault tree, applying correlative rule to judge the malfunction by the inference machine.
