A hypertext based diagnostic system for aiding in the detection of vibration defaults of rotating machines

We have shown in preceding papers the feasibility of developing a framework for building hypertext based diagnosis systems. It was based on a novel definition and implementation of hypertext systems, which are more appropriate to account for the structural properties which exist in any document describing a given engineering system. This framework also used a model ontology building method for representing our knowledge of a given system, its functioning process, as well as the occurrence of certain faults and the description of the corresponding diagnosis processes. In this paper we present the development of this approach in the case of the vibration diagnosis of rotating machines. We have developed an ontology of rotating machines by using the model ontology building method embedded in our hypertext system. It permits to browse across the ontological knowledge base for performing the diagnosis process. According to the information provided by the user (such as signals, observable sign, etc.), the system suggests diagnostic procedures and/or appropriate signal processing techniques, through dynamically created SGML documents
