Problems solved by technology

[0004] Since there are many sources of product structure data and are complex
Now there is no systematic and standardized demand data management, and it takes a lot of time for designers to manually process product structure data, resulting in repeated waste of R&D resources and delays in R&D progress
A large number of human influences lead to a high probability of error, which cannot meet the needs of rapid train development

Abstract

The embodiment of the invention discloses a method and a device for constructing a high-speed train product structure tree. The method comprises the following steps: acquiring product structural data of known high-speed trains, classifying the product structural data according to hierarchy information of the product structural data to obtain each product structure, acquiring structural information of the product structural data and distributing unique corresponding codes for the product structures; according to the obtained product structures, structural information and codes corresponding to the product structures, establishing a product structure tree; establishing an incidence relation of the product structure tree and demand data and when receiving demand data designed for a new high-speed train, according to the incidence relation and the product structure tree, generating known high-speed train product structure data corresponding to the known demand data in the demand data designed for the new high-speed train so as to improve efficiency of processing the product structure data, reduce human influence and reduce error probability.

Description

technical field [0001] The invention relates to the field of public transportation, in particular to a method and device for constructing a high-speed train product structure tree. Background technique [0002] The high-speed train product structure data is the data describing the material composition and the file composition of each part of each high-speed train research and development product, and it is an important basis for guiding product design. [0003] In the development of existing high-speed trains, when a vehicle manufacturer receives an order, it needs to manually decompose the technical indicators of the order into various component modules, such as load-carrying components, running components, and car body components. The R&D department corresponding to each component converts the corresponding technical indicators into product structure data according to the design personnel's own design experience and the requirements of the technical indicators. [0004] S...
