Automatic operation management method for large-scale low-earth-orbit satellite constellation operation control system

Abstract

The invention discloses an automatic operation management method for a large-scale low-orbit satellite constellation operation control system, and relates to the field of automatic control. Starting from various functions of a satellite ground operation and control system, dynamic generation of various events in satellite operation and control management is analyzed, and a real-time decision and task driving mechanism adapting to satellite complex task operation is studied in combination with operation management events. Meanwhile, conflict resolution under large-scale constellation and multi-task parallelism is comprehensively considered from the top layer design; a satellite operation management expert system is constructed, automatic identification and analysis of satellite-ground resource state monitoring information are realized, and a prediction means of a key parameter change trend is provided through combined reasoning of a current state and historical data; aiming at possiblefaults in a satellite-ground resource operation period, a fault knowledge base and an inference tool which are graded and planned are constructed, abnormity can be analyzed and judged at the first time, fault positioning can be performed and a feasible plan can be given after a system prompts and gives an alarm, and efficient service is provided for troubleshooting.

Description

technical field [0001] The present invention relates to the field of automation control, especially for the high-efficiency and stable automatic operation requirements of large-scale low-orbit Internet constellations, and the design of the automatic operation management method of the operation control system, the design idea can be applied to the command management system of the satellite ground operation management center, and at the same time The method can also be applied to the field of ground station network operation control management. Background technique [0002] With the development of my country's commercial aerospace industry and the successive start of various low-orbit satellite constellation projects, the number of satellites to be put into orbit and the scale of constellations have increased significantly compared with existing satellite systems. The overhead of satellite in-orbit management and operation control is also huge. The current in-orbit satellite ma...

[0005] 2) Fault diagnosis and treatment rely heavily on manual judgment

[0006] Compared with monitoring and management, which already has a primary level of automation, the early warning and diagnosis of faults are still in the stage of manual judgment. Often, faults are judged after a period of time and cannot be dealt with immediately.

Delayed fault handling can cause damage to system components and affect work efficiency, or miss the timing of handling in severe cases, resulting in catastrophic consequences
