The invention provides an on-orbit real-time monitoring method based on a satellite-borne relevance health baseline satellite. The method comprises the steps: 1, health baseline configuration; 2, datacaching and calculation triggering; 3, working condition judgment; 4, baseline searching and calling; 5, correlation calculation; and 6, abnormity judging. According to the method, a health baselinebased on an analytical equation is adopted, real-time on-orbit relevance monitoring is achieved, and the advantages of being small in computing resource occupation and low in computing time consumption are highlighted; and a cache pool timing triggering calculation method is adopted, so that the requirement on data storage is reduced, and meanwhile, the response speed is increased.
本申请提出一种基于星载关联性健康基线卫星在轨实时监测方法,其包括:第一步,健康基线配置;第二步,数据缓存与计算触发;第三步,工况判断;第四步,基线搜索与调用;第五步,关联性计算;第六步,异常判定。本方法采用基于解析方程的健康基线,实时在轨关联性监测,凸显其计算资源占用少、计算时间消耗少的优势;采用缓存池定时触发计算的方法,降低了对数据存储的要求,同时提升响应速度。
