Embodiment Construction

[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the public implementation manners of the present invention in detail with reference to the accompanying drawings.

[0048] refer to figure 1 , shows a step-by-step flow chart of a hierarchical whole-star autonomous emergency management method in an embodiment of the present invention. In this embodiment, the hierarchical whole-star autonomous emergency management method includes:

[0049] Step 101, according to the telemetry packets of each device on the satellite collected in real time, determine the abnormal state of the satellite, and generate the current safety mode word of the satellite.

[0050] In this embodiment, the real-time collected telemetry packets of each device on the star can be analyzed to obtain the parameters to be detected; according to the preset abnormality criteria of the equipment, the parameters to be detected a...

Abstract

The invention discloses a graded whole-spacecraft independent emergency management method and system. The method comprises steps: according to a telemetry packet of each onboard device which is acquired in real time, the abnormal state of the satellite is determined, and the current time security pattern word of the satellite is generated; from multiple preset graded emergency management modes, the current grade emergency management mode matched with the current time security pattern word is selected; and a security instruction sequence corresponding to the current grade emergency management mode is executed to carry out emergency management on the satellite. The problems of independent abnormity detection, abnormity isolation and state setting on the satellite in orbit can be solved, thesatellite security management flexibility is enhanced, and the risk of fatal abnormity happening to the satellite is reduced.

Description

technical field [0001] The invention belongs to the technical field of in-orbit satellites, and in particular relates to a method and system for self-emergency management of hierarchical whole satellites. Background technique [0002] When a satellite is in orbit, it spends most of its time flying abroad. Once a component of the entire satellite fails, it cannot be intervened and controlled in time by the ground, which may easily cause a failure of the entire satellite, affect the mission of the satellite, or even lead to catastrophic consequences. Therefore, it is necessary to combine The central computer is a feature of the entire satellite information control center. It reasonably sets up independent judgment methods and independent control measures for various faults to ensure the judgment and handling of faults when the satellite is flying overseas, and to ensure the reliability and safety of the satellite's in-orbit operation. Contents of the invention [0003] The t...
