Method and apparatus for building a demand metamodel for high-speed trains

摘要

A high-speed train demand metamodel construction and processing method, wherein all data of the high-speed train tree structure pre-built based on the structure of the high-speed train is acquired, and all of the pre-built high-speed train tree structure is obtained. Using data, sequentially selecting demand terms corresponding to each structural point in the tree structure of the high-speed train, specifying the demand terms as demand targets of the demand metamodel, and target attributes of each demand target of the demand metamodel Identifying attribute-related information, constructing a demand metamodel based on the target attribute and attribute-related information of each demand object, storing each constructed demand metamodel in a database, and configuring a demand metamodel database, When the demand metamodel call command is received, the demand metamodel database responds to the demand metamodel call command and responds to the demand metamodel data. Output to a includes building each structure of the high-speed train.
