| 摘 要： | 热轧加热炉集散控制系统(DCS)从检测单元到执行机构的各个单元之间存在着错综复杂的关系,其肿大量的是因果关系。本文针对其中的因果关系,结合故障树分析法便于对事件进行分析、易于转化为专家系统中的规则知识、规则推理具有直观性和速度快的优点,从而建立故障树。然后以故障树来获取和分析知识,以产生式规则建立知识库,以规则匹配来进行推理,从而建立起步进式热轧加热炉DCS故障诊断专家系统。此方案充分利用了故障树和专家系统在故障诊断中的优势。

| Abstract: | Quantities complicated relations exist between components from test and measurement units to executive units in the distributed control system of walking beam reheating furnace. In these relations ,large amounts are cause and effect relations. Firstly,this article chooses the cause and effect relations existing in the DCS to establish the fault trees,which takes full advantage of the fault trees'advantages of easy to analyze problems,easy to translate into expert system rules and quickly and clearly to matc... |
