Embodiment Construction

[0036] In an embodiment of the present invention, a method of applying a metamodel to a genealogy train configuration is provided. A typical metamodel structure can be described as: instance layer, model layer, metamodel layer and metametamodel layer. Each layer is described as follows:

[0037] 1. Information layer

[0038] Information is composed of data we want to describe, these data are usually some user data (user data), the main responsibility is to describe the detailed information in the information field.

[0039] 2. Model layer

[0040] The model layer is composed of metadata, which is the data describing the information layer, and the collection of metadata is called a model.

[0041] The main responsibility of the model layer is to define an "abstract language" (ie, a language without concrete syntax or notation) for describing the information layer. The data of the information layer, the user data, is an instance of the model layer.

[0042] 3. The metamodel...

Abstract

The present invention provides a metamodel-based high-speed train modeling method, comprising: establishing a high-speed train demand library; analyzing non-demand in the demand library to establish a metamodel; building a basic metamodel based on the metamodel, The basic meta-model has nothing to do with the pedigree design platform; on the basis of the basic meta-model, build a related data model related to the pedigree design platform; build a comprehensive data model of the pedigree design platform on the basis of the related data model ; Establish the design chain of the genealogical high-speed train data model, combine the entire genealogical model through the design chain, and establish the meta-model of the design chain. The meta-model is used in the genealogical design of high-speed trains, and the meta-model data model of genealogical high-speed trains is established to realize the collaborative and dynamic design of genealogical high-speed trains. To this end, a genealogical high-speed train design platform is established to speed up the development of high-speed trains, speed up the development, improve the development speed, and save resources.

Description

technical field [0001] The invention relates to a train model and a modeling method, in particular to a model and a modeling method of a pedigree high-speed train based on a meta-model. Background technique [0002] At present, high-speed trains have become one of the main means of transportation in my country. my country has built more than 5,000 kilometers of high-speed railways. The development direction of high-speed railways during the "Twelfth Five-Year Plan" period: with the high-speed train pedigree, intelligence, and energy-saving and consumption-reducing technologies as the core, the key technologies and major equipment systems related to high-speed trains in my country are basically formed. The pedigree of high-speed trains refers to the formation of different serialized products for different needs. For example, high-speed trains now have speeds of 200, 250, 300, and 350 kilometers per hour in terms of speed grades. In terms of passenger capacity, they are mainl...
