基于国内外远程诊断技术发展存在的问题,简要介绍了构建开放式设备故障诊断系统的内容,对CORBA技术进行了概要介绍.深入分析了基于CORBA设备远程诊断系统的开放式体系结构,提出了基于CORBA技术的企业诊断平台和远程诊断中心的实现方法,给出了运用远程诊断网进行设备故障诊断的一个实例,最后得出开放式故障诊断对象网合理有效的结论. Based on the existing problems in the development of remote diagnosis technology both at home and abroad, this paper briefly introduces the content of building an open equipment fault diagnosis system and gives an overview of the CORBA technology.An open analysis of the open architecture of the remote diagnosis system based on CORBA equipment is proposed, CORBA technology enterprise diagnosis platform and remote diagnosis center implementation method, gives a remote diagnosis network using equipment fault diagnosis an example, and finally draw an open fault diagnosis object network reasonable and effective conclusion.
