Communication fault detection and self-healing method between satellite internal loads and between satellites

The embodiment of the invention discloses a communication fault detection and self-healing method between satellite internal loads and between satellites. In a specific embodiment, the method comprises the following steps: establishing a detection loop between detection equipment and detected equipment; the detection device detects the detected device through the detection loop; and after a fault is detected, a fault source is pre-judged, and fault self-healing is carried out according to a preset self-healing action. According to the invention, a communication fault can be quickly found, and after the fault is found, fault self-healing is carried out, so that the maximum possible continuity of constellation network services is ensured; and automatic operation and support of detection loop reconstruction can be realized without manual intervention. 本发明实施例公开一种卫星内载荷间和卫星间的通信故障检测及自愈的方法。在一具体实施方式中，该方法包括：建立检测设备与被检测设备之间的检测回路；检测设备通过检测回路对被检测设备进行检测；检测到故障后，预判故障源，并根据预设的自愈动作进行故障自愈。本发明能够快速发现通信故障，发现故障后，进行故障自愈，以保证星座网络业务最大可能的持
