基于本体的液压系统故障诊断知识建模与推理

摘要

In order to realize integration and sharing of hydraulic systems fault diagnosis knowledge,and improve the efficiency of knowl-edge organization and maintenance of technical support,introduce ontology as a technical tool of knowledge modeling. Based on the anal-ysis of knowledge structure of hydraulic systems,take advantage of protégé3. 3. 1,protégé3. 4. 7,protégé4. 2 series version of the software and ontology construction method to build a hydraulic system fault diagnosis model and describe the ontology with OWL,realize graph-ical representation. Through hydraulic system detection rules of the hydraulic oil established by ProRace,Pellet,JESS reasoner and SWRL language finish ontology reasoning,realizing junior fault diagnosis. Provide a new technique for the effective management and use of do-main knowledge of the hydraulic system.%　　为了实现液压系统故障诊断知识集成与共享，提高知识组织和维修技术支持效率，论文引入本体作为知识建模的技术工具，在分析液压系统故障诊断知识结构、体系的基础上，利用protégé3.3.1、protégé3.4.7、protégé4.2系列版本软件和本体构建方法构建了液压系统故障诊断知识模型，并使用OWL语言描述了该本体，实现了本体的机器可读，通过Pro-Race、Pellet、JESS推理器和SWRL语言构建的液压系统液压油检测规则对构建的本体进行推理，实现了液压系统常见的故障诊断。初步实现了基于本体的知识建模，验证了模型的推理能力并应用于具体诊断，为有效地管理使用液压系统领域知识提供了新的技术手段。
