摘要: 机械设备群体协同服役是实现网络化协同制造的核心载体,对设备群体进行数据中心化的智能诊断,存在数据流通壁垒、个体差异显著的挑战难题。为突破数据流通壁垒、提升诊断模型的群体适应性,现有研究尝试建立去中心化、分布式的协同诊断架构,然而,在规划设备群体诊断任务时存在盲目性,且在融合各设备节点的局部诊断模型过程中,忽视了个体重要度分布不均的客观事实。对此,提出迁移拓扑规划的群体协同智能诊断方法,首先建立迁移拓扑结构,描述各设备节点之间诊断知识的流出与流入关系;然后综合考虑数据质量、可用数据量、诊断知识可迁移性、通信资源、个体重要度等多重因素,优化求解迁移拓扑规划问题,以确定设备群体诊断知识的流向关系与个体重要度分布;最后建立个体重要度加权的协同诊断架构,训练适用于设备群体的全局诊断模型。通过多台设备的轴承故障数据对提出方法进行验证,结果表明:优化后的迁移拓扑结构,能够有效地反映设备群体诊断知识的最佳流向关系,提高了全局模型的诊断精度与群体适应性。

Abstract: Machine group collaborative service is central to networked collaborative manufacturing. Performing data-centralized intelligent diagnosis for such groups faces challenges like data barriers and individual differences. To overcome data barriers and enhance model adaptability, current approaches based on federated learning and multi-domain adaptation establish decentralized diagnosis architectures. However, they exhibit blindness in group task planning and neglect uneven individual importance when integrating local models. To address this, we propose a collaborative swarm intelligent diagnosis method with transferability topology planning. First, a transferability topology structure is established to define diagnosis knowledge flow among machine nodes. Second, the topology planning is optimized by comprehensively considering data quality, available data amount, diagnosis knowledge transferability, communication resources, and individual importance, thus determining knowledge flow relationships and individual importance distribution. Finally, an individual importance-weighted decentralized diagnosis architecture is built to collaboratively train a global diagnosis model for the machine group. Validation experiments using bearing fault data from multiple devices show that the optimized transferability topology can effectively reflect knowledge flow relationships among machine nodes. This improves the diagnosis accuracy of global model and enables its adaptability for machine group diagnosis.
