摘要
随着我国航天技术的不断发展,卫星系统所携带的载荷设备更加多样,其承载的任务和功能也愈加广泛,卫星故障监测与诊断也变得更加复杂。针对目前卫星故障诊断中涉及的卫星结构、故障问题报告、诊断手段及其他数据存在数据孤岛,无法系统地诊断卫星故障,及故障诊断参考历故障困难等问题,提出了基于知识图谱的卫星故障诊断系统构建方法,通过构建知识图谱,将卫星相关的多种数据整合起来,建立实体之间的关联关系,提供可视化和分析能力,为故障诊断和决策提供支持。
With the continuous development of China′s space technology,the load equipment carried by the satellite system has become more diverse,and the tasks and functions carried by it have become more extensive.Meanwhile,the satellite fault monitoring and diagnosis have become more complex.In view of the problems involved in satellite fault diagnosis,such as the existence of data silos in satellite structure,fault problem reports,diagnostic means and other data,the inability to systematically diagnose satellite faults,and the difficulty of fault diagnosis reference history faults,this paper proposes a method to build a satellite fault diagnosis system based on knowledge graph,by building a knowledge graph,integrating multiple data related to satel-lites,and establishing correlations between entities.It provides visualization and analysis functions to support fault diagnosis and decision making.
