On-orbit autonomous management system for satellite and autonomous management method

Abstract

The invention relates to an on-orbit autonomous management system for a satellite and an autonomous management method. Through a method of innovatively leading a bus data monitoring unit and performing state data issuing through unified scheduling for a sub-system on each satellite, state information is directly collected to the bus data monitoring unit, and data extraction by a satellite mission central computer is not required. The bus data monitoring unit directly combines related information for forming alarm information and transmits the alarm information to the satellite mission central computer, thereby saving time in time-sharing acquisition remote sensing and state information data extraction, buying expensive time for treating the fault in time, and improving a fault treating efficiency. A distributed data management method is used for optimizing the operation process of the satellite mission central computer and can simultaneously treat multiple fault alarms which simultaneously occur, thereby realizing intelligent operation for sequencing according to the damage degree and emergency degree of the fault, and maximally ensuring in-time recovery of key system states such as satellite energy and satellite gesture when multiple faults simultaneously occur.

Description

technical field [0001] The invention relates to a satellite on-orbit autonomous management system and an autonomous management method, in particular to a method for real-time processing of satellite health and status data by using a satellite center computer and a bus data supervision unit to realize satellite status self-monitoring and failure self-processing. Background technique [0002] At present, small satellites adopt a hierarchical self-management scheme based on the computer of the star service center, that is, the bottom-level self-management (stand-alone / system-level self-management) and the top-level self-management (whole-star self-management) are carried out simultaneously to realize the self-management of the whole star. The underlying autonomous management relies on the capabilities of stand-alone equipment and individual subsystems to realize self-monitoring and self-handling of equipment faults, and isolate faults at the system level. Bottom-level autonomo...
