基于本体的移动通信基站故障诊断研究

在对移动通信基站结构及故障分析的基础上，提出将本体用于基站故障诊断的思想。建立移动通信基站知识库，该知识库由设备功能本体、设备本体和设备龊障本体构成，通过将当前状态和知识库中知识进行匹配，判断出设备的状态，给出其深层次的原因，并决定是否更新知识库。最后经protege3．1．1仿真证明，该方法不仅利于移动通信基站领域知识的共享，提高故障诊断效率，而且利于知识库的扩充。

Analysis of Mobile Communication Base Station Fault Diagnosis Based on Ontology

After analyzing the configuration and the fault characteristic of mobile communication base station, the ideal of fault diagnosis based on ontology was presented. The knowledge base of the mobile communication base station which consist of three ontologies-functional ontology, equipment ontology and fault ontology was constituted. It can judge the state of the device and provide deep cause by matching the current state and the knowledge in the knowledge base, and gives suggestion of whether to extend the knowledge base or not. At last the imitation by protege3.1.1 shows that the method can not only be useful in knowledge reusing and fault diagnosis but also benefits knowledge extending.
