摘　　要：目前,大多数航天器的测控与通信分系统的自主健康管理功能局限于物理层设计,缺乏基于分层结构的系统设计,难以适应特殊工况。针对航天器长期在轨自主飞行对测控与通信分系统的需求,提出一种分层结构的自主健康管理方法,分别从物理层、数据链路层和应用层进行设计。物理层从“看门狗”和回读重配置2个方面开展设计;数据链路层完成基于射频链路的自主检测设计;应用层分别完成导航接收机自主健康监测、航天器掉电恢复后自主建链和发射机的自动功率控制策略设计。该方法在地面测试及在轨飞行中的验证结果表明:它能分别从物理层、数据链路层和应用层实现航天器测控与通信分系统的自主健康管理功能,适应航天器长期在轨自主飞行的需求及特殊工况。At present,the autonomous health management method of TT&C(tracking,telemetry and command)telecommunication subsystem for most spacecraft is limited to the physical layer design,making it difficult to adapt to special operating conditions.In order to meet the requirements of long-term autonomous flight of spacecraft in orbit for TT&C telecommunication subsystem,a layered autonomous health management method is proposed,which is designed from the physical layer,data link layer and application layer.The physical layer has respectively completed the design of watchdog and read back reconfiguration.The data link layer has completed the independent detection design based on the RF(radio frequency)link.The application layer has respectively completed the design of autonomous health monitoring for navigation receiver,autonomous chain building of power-off recovery,and automatic power control strategies for transmitters.The verification is carried out in the ground test as well as the orbit flight,and the result shows the method proposed is suitable for the needs and special operating conditions of long-term autonomous flight of spacecraft in orbit.
