为提高生产制造设备的有效作业率，减少故障停机时间，本文提出一套指导生产线上故障停机诊断知识的本体构建原理和规则。以冲压车间为研究背景，基于对故障诊断过程的分析，建立以故障现象、故障原因、方案推荐和故障源4个基本知识域为核心的本体结构，并根据基本知识域间的语义关系，建立域间知识的多重关联，为故障停机诊断过程的语义推理、查询和智能理解奠定基础。最后，介绍以本体为内核的故障停机诊断系统，该系统主要实现故障停机诊断知识的语义标注和知识推理。

To improve effective operation rate of equipment and reduce fault downtime, this paper proposes a set of principles and rules to guide the construction of fault downtime stamping workshop is constructed through drawing out the core diagnose on automatic production line. An ontology for concepts of the course as well as the relations among the concepts. This work provides a foundation for ontology-based semantic reasoning,querying,and knowledge analyzing. Moreover,the paper describes a system as the core with fault downtime ontology. The system has mainly realized semantic noting and knowledge reasoning based on ontology.
