【摘要】 设备的状态监测与故障诊断是设备维护与管理工作的重要内容。现代化工业大生产的不断发展和科学技术的日益进步对设备的状态监测与故障诊断提出了新的要求：它需要解决技术资源与企业相分离的矛盾，对设备故障进行及时、准确的诊断，从而降低企业的运营成本，提高企业的核心竞争力。因此，远程设备故障诊断技术成为众多专家学者的研究热点。 本文以CIM哲理为指导提出了一种新的面向流程CIMS的设备集成维护与管理系统，设计了设备集成维护与管理系统的网络体系结构，研究了该系统运行的工作流程，分析了系统信息集成、过程集成与优化和资源集成与优化等技术特性。并对实现系统资源集成与优化的远程协同诊断子系统进行了重点研究。 本文对远程协同诊断进行了总体描述，确定了远程协同诊断平台应具有的功能，并将CSCW技术引入到远程协同诊断系统的研究中来，结合CSCW的概念、分类、要素和关键技术，阐述了远程协同诊断与CSCW的关系。 本文在对远程协同诊断过程中的可能事件进行分析综合的基础上，以用例图和活动图的形式建立了系统的需求模型，形式化、图形化地描述了系统的需求；以序列图的形式详尽的描述了需求模型中用例图各用例的关键场景，通过对序列图中参与交互的对象进行抽象，归纳出了远程系统诊断平台初步的类图和包图，为系统的最终实现提供指导模板。 本文对实现远程协同诊断系统的两个关键技术——IP组播和基于RTP(Real-Time Transport Protocol，实时传输协议)的多媒体通信进行了比较深入的研究；并在Window2000环境下，以Jbuilder9为开发工具，开发建立了设备故障远程协同诊断系统原型，实现了系统的部分功能。更多还原

【Abstract】 Condition monitoring and fault diagnosis of machinery is the important component of plant management & maintenance. Because of the rapid development of science and technology, new requirement is put forward to condition monitoring and fault diagnosis of machinery: the separation between the technology resource and enterprise need be solved in order to diagnose the machinery fault fleetly and accurately. Therefore, the technology of remote fault diagnosis has become the research focus of numerous experts and scholars.A integrated plant maintenance and management system for process CIMS is designed and the technology of CSCW is introduced briefly in this thesis. And based on these points, a new mode of remote fault diagnosis, namely the remote cooperative diagnosis, is studied emphatically.The remote cooperative diagnosis is described overallly; the relation between it and CSCW is expounded; the functions of the remote cooperative diagnosis system are also founded.In order to construct the remote cooperative diagnosis platform, the demand model and the analytical model based on Unified Modeling Language are built from the system modeling viewpoint. These models form the direction template for the sequential design and implementation of the remote cooperative diagnosis platform.At last, after two key technology, including IP multicast and communication of multi-media based on RTP, is researched deeply, a prototype of the remote cooperative diagnosis platform is set up, which realizes partial functions of the remote cooperative diagnosis system.更多还原
