摘要
以道岔动作电流曲线为分析对象,提出了一种基于产生式表示法的专家知识和决策树的道岔状态诊断方法。详细描述了S700K道岔故障树建立方法、专家知识的存储及故障诊断的逻辑推理,可实现道岔异常的自动预警和道岔故障的自动定位功能。
Taking the switch action current curve as analysis object, we propose a fault diagnosis method based on expert knowledge and decision tree using production representation. The con- struction method of the fault tree for ST00K switch and the storage of expert knowledge and logi- cal reasoning are described. This method can realize automatic alarming of track abnormities and pinpointing the switch faults.
