Requirement meta-model instance construction method and device of high-speed train customization type

The invention discloses a requirement meta-model instance construction method of a high-speed train customization type. The requirement meta-model instance construction method comprises the following steps: obtaining a requirement instance of the customization type, the requirement meta-model template of the customization type and a structural tree data template of a standard type; comparing requirement items in the requirement meta-model template of the customization type with the requirement items in the structural tree data template of the standard type to obtain the requirement meta-model template which has the same requirement items with the structural tree data template of the standard type; and writing the requirement instance of the customization type into the requirement meta-model template which has the same requirement items with the structural tree data template of the standard type to obtain the requirement meta-model instance of the customization type. The requirement instance of the customization type, the requirement meta-model template of the customization type and the structural tree data template of the standard type are acquired to obtain the requirement meta-model instance of the customization type, the requirement meta-model instance of the customization type is obtained on the basis of requirement motivation, and therefore, the customization research and development of the train can be quickly finished.
