A Computation Model Based on Data Fusion for Equipment Fault Diagnosis

针对故障诊断的数据融合功能模型中各级融合和各项融合功能及处理任务 ,以集合论和实变分析为基础提出了故障诊断的数据融合处理过程的计算模型 .计算模型描述了数据融合处理步骤、过程的数据形式与计算方法 .证明了这些模型的正确性和可用性 ,为数据融合的故障诊断技术奠定了理论基础 .通过分析得出数据融合处理不完全依赖于具体计算方法的结论 .

A computation model for fault diagnosis based on data fusion process has been proposed. using set theory and real function analysis. The data format and computing methods in the process of data fusion have been described with the computation model, and the validity and serviceability of these models has been proved. The conclusion drawn by analying the model is that data fusion process does not rely on the calcucation method only. The calculation model of data fusion system plays an important orle in designing the fault diagnosis system.
