摘要
在面向对象的故障树层次诊断模型基础上，提出用于故障诊断的模糊高级Petri网模型，并应用于载人飞船故障诊断中。该方法使故障诊断的推理过程简单、直观，并从面向对象和层次化角度解决了故障事件信息及操作特性的封装、模块化和故障传播的层次性，有利于系统故障的层次性诊断。
Fuzzy high Petri nets for manned spaceflight's fault diagnosis is brought forward based on object－oriented hierarchy fault tree. This new method makes the inference of hierarchy fault diagnosis simple and direct, and solves problems to sealing and modulates fault event.
