Research on Architecture of Distributed Fault Diagnosis System for Complex Equipment

Complex equipments are optical-mechanical-electrical products, whose structures are complicated, and which scatter largely. In addition, diagnosis resources are limited. So maintaining the equipments is difficult. This paper presents the architecture of fault diagnosis system for complex equipments based on the network according to Condition-Based Maintenance (CBM) in order to solve the problem of maintaining the complex equipments. The concept of multi view is introduced to show the detailed features of the fault diagnosis system. The system architecture is fully described in operational structure, logical structure, major function, collaborative diagnosis, and information flow respectively on the basis of the multi view. This paper is the important theoretical basis of designing the practical fault diagnosis system.
