The method according to claim 2, characterized in that, after the global classification attribute declaration is generated based on the original component instance and the classification attribute field, the method further comprises: When there is a classification attribute declaration corresponding to the original component instance and different from the global classification attribute declaration in the classification attribute declaration set of the design file, declare the classification attribute corresponding to the original component instance in the classification attribute declaration set replaced by the global classification attribute declaration, the set of classification attribute declarations comprising the classification attribute declarations of all model element instances; When the classification attribute declaration corresponding to the original element instance does not exist in the classification attribute declaration set, the global classification attribute declaration is added to the classification attribute declaration set. 4. The method according to claim 3, wherein after the adding the attribute instance to the original component instance to generate a model component instance, the method further comprises: According to the updated classification attribute field of the original component instance in the specified database, obtain the updated classification attribute declaration set; updating the global classification attribute declaration in the model element instance based on the updated classification attribute declaration set to obtain an updated classification attribute declaration; generating an update attribute instance based on the classification attribute field and the update classification attribute declaration; The model element instance is updated by replacing the specified attribute instance in the original element instance with the updated attribute instance. 5. The method according to claim 1, characterized in that, before acquiring the original component instance and the classification attribute field of the original component instance from a specified database, the method comprises: Create an instance of the original component; The original component instances are inventoried into a designated database based on the classification. 6. The method of claim 5, wherein the creating an instance of an original element comprises: Define the basic information of the original component, the basic information includes the name of the original component, the description of the original component, the classification of the original component, and the specialty of the original component; Define the model information of the original element, the model information includes the model name and the model file name; A primitive element field is defined that is inherited from the class attribute field of the primitive element's parent. 7. The method according to claim 5, wherein the storing the original component instance into a specified database based on the classification comprises: Define basic classification information, where the basic classification information includes classification name, classification description, and classification parent name; Define a classification inheritance field, the inheritance field is an attribute field of the classification parent; Define a category own field, the category own field is a category-specific field, and the category own field cannot be the same as the category parent name; The original component instances are inventoried into a designated database based on the classification. 8. A device for establishing model attributes, wherein the device comprises: an obtaining module, used to obtain the original component instance and the classification attribute field of the original component instance from the specified database; a first generation module, configured to generate a global classification attribute declaration based on the original component instance and the classification attribute field; a second generation module, configured to generate an attribute instance based on the classification attribute field and the global classification attribute declaration; An add module is used to add the attribute instance to the original element instance to generate a model element instance. 9. An electronic device, characterized in that the electronic device comprises a memory and a processor, wherein program instructions are stored in the memory, and when the processor executes the program instructions, executes any one of claims 1-7 Steps in the method described in item. 10. A storage medium, wherein the storage medium stores computer program instructions, and when the computer program instructions are executed by a processor, the steps in the method according to any one of claims 1-7 are executed .
