【摘要】 本文对基于故障树的集装箱装卸桥失效诊断专家系统进行了探索和研究。故障树方法是分析复杂系统失效问题的有效方法之一。用控制系统失效分析故障树的信息和规则来建造知识库,运用正向推理机制构建专家系统,通过人机接口进行树的搜索和匹配,从而达到控制系统失效诊断的目的。由此突出了故障树分析法在建造大型复杂的失效诊断专家系统中的重要作用。更多还原

【Abstract】 Research on a fault diagnosis expert system based on the fault tree analysis(FTA)method for crane drive control system ismade.FTA is one of the effective methods for analyzing the failure of a complicated system.Information and rules of the FTAmethod for control system are adopted to build the knowledge bank.The expert system is made up of an obverse reasoningmechanism,and the fault diagnosis for control system is realized by the searching and matching through a man-machine interface.Hence,the importance of FTA is stressed in building a large complicated fault diagnosis expert system.更多还原
