基于本体的装备PHM信息共享技术研究

Technology of Sharing for Equipment PHM Information Based on Ontology

针对装备PHM工作过程中存在的信息异构、难以共享的问题,基于本体对装备PHM领域信息进行建模,采用基于语义相似度的检索方法对装备PHM领域本体进行检索,在MyEclipse平台上搭建了装备PHM信息共享原型系统,并以装备测试诊断信息为例在原型系统上应用,能够满足用户获取并运用装备PHM信息的需求,基本实现了装备PHM信息共享功能。

According to the problems of heterogeneous information and difficult to share in equipment PHM working process,the perception information of equipment PHM is modeled based on ontology,and the domain ontology of equipment PHM is retrieved using the retrieval method based on semantic similarity.A prototype system of equipment PHM information sharing is built on MyEclipse platform.Taking equipment test and diagnosis information as an example,the system can meet the needs of users to acquire and use equipment PHM information,and basically realize equipment PHM information sharing function.
