Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0028] After 50 years of development, a large amount of design resources and design data have been deposited in the overall design of spacecraft. These data have the characteristics of complex structure, numerous formats, and relatively closed-loop design data between subsystems. In order to better integrate these The data is applied to the subsequent spacecraft model development process, so that the knowledge acquisition of these data is more rapid, reliable, and convenient in the model development process. It needs to be based on the design data generated during the overall design process of these spacecraft. The design data builds a knowledge graph or knowledge base for the overall design of the spacecraft. Based on this, the embodiment of the present invention proposes a k...

Abstract

The embodiment of the invention discloses a knowledge acquisition method and device for spacecraft overall design and a storage medium. The method comprises the steps: dividing design data formed in the overall design process of a spacecraft into structured spacecraft design data and unstructured spacecraft design data; mapping the structured spacecraft design data into resource description framework RDF format data by utilizing a set strategy from a database to a resource description framework D2R; constructing the unstructured spacecraft design data into RDF format data through a set information extraction and man-machine interaction strategy; and based on the RDF format data corresponding to the structured spacecraft design data and the RDF format data corresponding to the unstructuredspacecraft design data, constructing a knowledge base oriented to the overall design of the spacecraft.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of spacecraft design, in particular to a knowledge acquisition method, device and storage medium for the overall design of spacecraft. Background technique [0002] The research and development of domestic spacecraft has experienced 50 years of development, accumulated a large amount of design knowledge and rich professional experience, and formed rich and valuable knowledge resources including technical indicators and design manuals. These knowledge resources have been tested by a large number of physical experiments and multiple model developments, and have great guiding significance and application value in the development of spacecraft. However, regarding the overall design of the spacecraft, despite the accumulation of a large number of design resources after 50 years of development, the data of these design resources has the characteristics of complex structure, numerous forma...
