Embodiment Construction
[0018] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.
[0019] In recent years, integrated electronics has become more and more mature, commercial aerospace has developed rapidly, commercial satellites are more systematic in design, and the cooperation of various functional systems is closer. In this context, the present invention proposes a computer fault diagnosis based on a third party. The processing method is to solve the problem of smooth transition in computer failure recovery and switching during satellite business operation, so that the system composition and attitude of the satellite will not change greatly in the case of computer failure, and the business operation will not be interrupted.
[0020] Generally, the on-board computers are dual-computer cold backup, and the fault diagnosis and ...
