摘　　要：PHM技术作为一种实际应用环境下的系统故障诊断与预测技术,在我国的卫星设计领域尚处于初步研究阶段,研究适合卫星信息系统特点的故障预测与健康管理系统,对今后卫星系统设计与测试技术的发展具有重要意义;文章针对当前卫星信息系统技术通道资源有限、遥测采样率较低、以单机诊断为主等特点,探讨了以星地三级闭环为特征的卫星PHM系统构架设计方案,分析了系统中涉及的关键技术,并对PHM技术对卫星地面测试技术发展的影响进行了阐述。As a systematic fault diagnosis and prediction technology in the actual application environment, PHM is still in the preliminary study stage in China＇s satellite design. The designing of the PHM system suited to satellite information systems plays an important role for future development of satellite design and test technique. The current satellite information system is mainly featured as low telemetry sam pling rate, limited channel resources and stand--alone diagnostic. According to these characteristics, the paper devises the PHM system ar- chitecture, and analyzes the key technologies to build the designed architecture. The potential impact on the development of satellite ground test by the PHM technology is also elaborated.
