摘　　要：针对远程诊断中缺乏会诊管理和协调机制的问题,提出了基于Internet开放式架构的虚拟诊断中心的概念,设计了虚拟诊断中心的结构方案和专家协作机制.围绕被诊断对象构建了故障案例、基于ActiveX的分析工具和多媒体会议为一体的会诊环境,提高了会诊效率,并通过Web Service接口实现了远程专家设备状态数据和案例的共享,支持了专家的协作研究工作.同时,通过采用设备信息管理开放系统联盟提出的机械信息数据库结构,克服了以往会诊系统只针对特定企业监测系统的缺点,并利用SQL Server的推订阅技术上传企业Intranet设备数据库的状态数据,保障了企业设备状态数据库的安全性.该诊断中心已在武钢大型轧钢厂加热风机、西安交通大学检测所的转子实验台上进行了初步应用,结果表明其系统结构合理,运行稳定,使用方便.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 active X-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.
