摘要: 针对航天产品总装过程多源异构数据整合困难、质量问题关联追溯效率低的问题,提出一种基于知识图谱的质量追溯方法。通过构建涵盖物流吊装、电缆网导通和综合测试关键场景的知识图谱,整合结构化与非结构化数据,实现跨环节数据的语义关联与深度推理。结合YOLOv8与DeepSORT算法实现物流吊装场景的实时目标检测与行为分析,利用K近邻算法对电缆网导通及综合测试场景的异常数据进行异常判断,基于知识图谱构建“异常-原因-解决方案”联动推理机制,突破传统质量追溯方法的数据孤岛限制,为总装质量问题定位与根因分析提供可解释性支持。案例验证表明,该方法可有效解决航天产品总装过程中的数据孤岛问题,提升异常定位与质量追溯的准确性与效率,为复杂总装场景的智能化质量管控提供技术支撑。

Abstract: To address the challenges of integrating multi-source heterogeneous data and inefficient association and tracing of quality issues in the assembly process of aerospace products, this study proposes a knowledge graph-based quality tracing method. By constructing a knowledge graph encompassing critical scenarios including logistics and hoisting, cable network conductivity, and comprehensive testing, we integrate structured and unstructured data to achieve cross-process semantic association and deep reasoning of data. The approach combines YOLOv8 and DeepSORT algorithms for real-time object detection and behavior analysis in logistics/hoisting scenarios, while employing the K-nearest neighbors (KNN) algorithm for anomaly detection in cable network conductivity and comprehensive testing scenarios. A collaborative reasoning mechanism of "anomaly-cause-solution" is established through the knowledge graph, breaking through the data silo limitations of traditional quality tracing methods and providing interpretable support for quality issue localization and root cause analysis in product assembly. Case validation demonstrates that this method effectively resolves data silo issues in aerospace product assembly, enhances the accuracy and efficiency of anomaly localization and quality tracing, and offers technical support for intelligent quality management in complex assembly scenarios.
