故障诊断网格任务调度模型的研究张建军 冯 静 张 利 徐 娟


摘 要:由远程协同故障诊断与网格技术的有机结合所形成的故障诊断网格,把广域分布的专家知识、检测设备、分析软件等定义为诊断资源,而诊断资源的组织和优化调度是系统有效运转的关键。从而提出了故障诊断网格中任务调度的体系结构,分析了故障信号分解、分配至诊断资源的工作流程,并通过Gridsim结合多种调度目标进行模拟仿真,验证了该任务调度模型的可实施性。

  Abstract:Fault diagnosis grid was the organic integration of the remote collaborative fault diagnosis and grid technology. This paper defined the wide-area distribution of expertise, test equipment, analysis software as diagnosis resources. And the organization and optimization scheduling of the diagnosis was a key to system operation effectively. It presented the task scheduling architecture in fault diagnosis grid and the analysis of the process of the fault signals decomposition and allocation to the diagnosis resources. And through Gridsim simulation combined with a variety of scheduling targets, the validity of the task scheduling model can be implemented. ......
