Problems solved by technology

[0004] 1) The fault isolation operation is cumbersome
Fault isolation is restored to the forbidden state by setting related fault detection and isolation. This operation must be performed for each fault strategy of the same category and the fault. The operation is cumbersome, not universal, and easy to miss
[0005] 2) The new failure strategy must be at the expense of deleting the existing functions of the software

Abstract

The invention discloses a satellite fault detection isolation recovery strategy and strategy dynamic adjustment method. The method comprises the following steps: according to a remote control instruction, dynamically adjusting a satellite fault detection isolation recovery strategy; sequentially removing the fault detection isolation recovery strategy in a fault detection isolation recovery strategy queue, and according to the fault detection isolation recovery strategy, carrying out fault detection; and if a fault detection result indicates that a fault is generated, performing fault isolation and fault recovery. According to the invention, the disadvantage that conventional spaceborne embedded software has to realize software added functions through such complex methods as a hook function, replacement of conventional functions, modification of stack windows and the like is solved, the adjustable capability of the satellite fault detection isolation recovery strategy is improved, and a good application foundation is provided for a future XX-3B satellite platform.

Description

technical field [0001] The invention relates to a satellite fault detection, isolation, and recovery strategy and strategy dynamic adjustment method. On the basis of realizing satellite fault detection, isolation, and recovery, taking into account satellite operation status and ground command operation requirements, a corresponding satellite fault detection, isolation, and recovery strategy is added / deleted, The invention relates to dynamically adjusting satellite fault detection, isolation and recovery strategy, which belongs to the technical field of embedded software reliability design. Background technique [0002] Fault Detection, Isolation and Recovery (FDIR) refers to the real-time detection of faults occurring in the entire satellite, locating the faults and ensuring the safe and reliable operation of satellites through measures such as reconstruction, which has become a must for domestic and foreign spacecraft. missing functionality. Fault detection is the ability ...
