基于铁路设备故障诊断专家系统研究--模糊推理原型分析

为了保证铁路信号设备的安全性,采取必要的措施对其运行状态,尤其是故障状态进行监测和诊断是十分重要的,目前我国车站信号设备微机监测系统已经在全路广泛应用,绝大部分车站都可实现设备工作状态信息实时监测,而故障诊断决策支持系统仍处于研究开发阶段.论文针对系统原型进行分析,以基于规则和判定树概念的知识表示方法和模糊规则的推理方法的推理方法等进行分析研究.

Based on Expert System Research of Railway Equipments Fault Diagnosing-- fuzzy inference model analysis

In order to guarantee the security of the railway signal devices,it is very important to take essential measures to monitor and diagnose its operation state,especial the fault state,The computer monitoring system of the railway station signal devices in our country has been already in the extensive application of the whole way at present,but the DSS of fault diagnoses is still at a stage of researching and developing.This paper compares knowledge expressing methods that is rule-based and uses concept of ludge trees,and compares reasoning methods that is based on fuzzy rules.
