基于分布式层次模型的诊断技术研究与应用

针对大型分布式系统故障诊断的复杂性,给出了一种基于分布式层次模型的诊断方法。详细介绍了基于语言的分布式诊断技术的相关工具和概念。深入研究了层次模型的构建技术、计算方法策略和多步诊断步骤。在某卫星测控系统中的应用结果表明,此方法降低了诊断的复杂性,诊断结果正确,适用于卫星这类复杂系统的故障诊断。

Research and Application of Diagnosis Technique Based on Distributed Hierarchical Model

According to the complexity of fault diagnosis for large scale distributed system,a diagnosis technique based on distributed hierarchical model is given in this paper.The tools and concepts associated with distributed diagnosis technique,which is based on language are introduced in detail.Then construction skill,computation method and multi-diagnosis procedure of hierarchical model are deeply researched.Finally,the application of this distributed diagnosis technique in a satellite tracking telemetry and command(TT&C) proves that the complexity of diagnosis is reduced,the diagnosis result is correct,which is suitable for fault diagnosis in complex satellite system.
