A method for fast multi-dimensional classification of space vehicle fault is disclose

Abstract

The invention relates to a multi-dimensional fast classification method of space aircraft faults, which relates to the field of space safety. The invention comprises the following steps: step 1, establishing a keyword retrieval directory of fault classification; 2, acquiring fault information of the aircraft; 3, fragmenting the fault information of the aircraft according to the keyword retrieval directory of the fault classification; 4, establishing a fault tag; 5, tagging that fault information of the aircraft after the fragmentation procesing in the step 3; 6, establishing an aircraft faultstandard library, and storing that tag processing aircraft fault information in the aircraft fault standard library; 7, searching and querying that keyword from the aircraft fault standard library toobtain the required fault information; The invention is applicable to the fast classification analysis of the faults of various spacecraft in the future, and is of great significance to the research of the fault rule and the rescue mode of the future spacecraft.

Description

technical field [0001] The invention relates to the field of space safety, in particular to a multi-dimensional rapid classification method for spacecraft faults. Background technique [0002] The orbital rescue system performs function recovery rescue for damaged satellites. The Orbital Rescue System has a wide range of military-civilian dual-use potentials. It is located in an area where national defense, military and commercial aerospace highly overlap. It is an important support for the development of military-civilian integration. It has important development potential and Value. [0003] The world's major aerospace powers have carried out relevant research on fast-response launch vehicles and on-orbit service technologies. my country has been in the follow-up stage in space satellite rescue and other technologies. The gap is mainly reflected in the late start, less flight verification, and low technology maturity. There is no report on the classification method of spa...

Problems solved by technology

[0003]The world's major aerospace powers have carried out relevant research on fast-response launch vehicles and on-orbit service technologies. my country has been in the follow-up stage in space satellite rescue and other technologies, and the gap is mainly reflected in With a late start, few flight verifications, and low technology maturity, there are no reports on the classification method of space faulty aircraft. The proposal and application of the classification method of space faulty aircraft are of great importance to the use, rescue and reasonable allocation of space resources of future space vehicles. of great significance
