基于 CORBA规范的公共对象请求代理技术 ,构建分布式故障诊断系统。诊断模块经过封装并实现为诊断对象 ,诊断对象加入分布式平台 ,并对外提供服务接口 ,客户通过 ORB实现对异构诊断对象的接口调用 ;利用已有的诊断对象可装配成面向具体设备的故障诊断系统。该体系的工程应用具有良好的效果和发展前景 Public Object Request Broker Based on CORBA Specification to Construct Distributed Fault Diagnosis System. The diagnostic module is encapsulated and implemented as a diagnostic object, the diagnostic object is added to the distributed platform, and a service interface is provided to the outside. The client invokes an interface call to a heterogeneous diagnostic object through the ORB. The existing diagnostic object can be assembled into a device-specific fault Diagnostic system. The system engineering application has good effect and development prospect
