Study.on the Consultation Mechanism of an Internet-Based Remote Fault Diagnosis System

Aimed at the deficiency of the mechanism of management and consultation, an idea of an internet-based Virtual Diagnosis Center （VDC） for machine fault is proposed, and the key elements of remote consultation are abstracted. Around the key elements, the construct scheme and cooperative mechanism among experts of VDC are designed. According to the diagnosed object, the context knowledge of a fault machine, fault cases and ActiveX-based analysis tools are integrated into a multimedia consultation environment in VDC to enhance the efficiency of expert consultation. Simultaneously, the technique of push subscription in a SQL Server is utilized to collect machine condition data in an enter- prise machine condition database, which ensures the security of the database. The VDC system in Xi＇an Jiaotong University has been applied to remote diagnosis of a blower in Wuhan Iron and Steel Corporation and the system construction reasonableness and the running stability are verified.
