Aimed at the deficiency on mechanism of management and consultation, the idea of
internet-based virtual diagnosis center (VDC) for machine fault with open structure is
proposed, and the construct scheme and cooperative mechanism among experts of VDC are
designed. According to the diagnosed object, the machine information, condition data,
fault cases and activeX-based analysis tools are integrated into multimedia consultation
environment in VDC to enhance the efficiency of expert consultation environment.
Simultaneously, to support the research of experts, machine data in VDC are open for the
experts by web service interface, and the technique of push subscription in SQL-server is
utilized to collect machine condition data in enterprise machine condition database, which
ensures the security of the database. The VDC has been applied to remote diagnosis of a
blower in Wuhan Iron and Steel Corporation and a rotor experiment kit in Xi'an Jiaotong
University, and the reasonableness of the system construction and the running stability
are verified.
