摘要

摘要: 针对工业过程中故障发生源与故障信息在传播过程中的差异性问题, 提出了一种基于不同故障传播路径差异化的故障诊断方法. 该方法分别从故障源邻域信息关系和故障信息传播两个角度出发, 设计了基于k近邻筛选和基于剪枝的k跳可达路径选择的两种故障源图的构建方式, 构建“故障源图”. 从故障在变量间的差异化表现着手, 将基于特征的分类问题转换为基于结构关系的图匹配问题, 利用该结构化信息优化过程特征, 提升模型故障诊断性能. 最后, 通过田纳西−伊斯曼过程和某海底盾构掘进施工过程进行仿真验证, 实验结果证明了所提方法的有效性.

Abstract: In order to address the issue of variability of fault sources and fault information in the propagation process in industrial processes, this paper proposes a fault diagnosis method based on Fault Propagation Path-Aware Network. The method is based on two perspectives of fault source neighbourhood information relationship and fault information propagation, and designs two ways of constructing fault source graphs based on k-nearest-neighbour filtering and pruning-based k-hop reachable path selection to construct a “fault source graph”. Based on the differentiation of faults among variables, the feature-based classification problem is viewed as a graph matching problem based on structural relationships, and the structural information is used to optimise the process features and improve the fault diagnosis performance of the model. Finally, the simulation is verified by the Tennessee-Eastman process and a submarine shield boring construction process, and the experimental results prove the effectiveness of the proposed method.
