Abstract

A system for building data exchange includes an information modelling unit, which includes a digital twin model, a building information modelling, wherein the information modelling unit provides modelling data, an extractor configured to determine extraction data from an instance, an extractor configured to determine extraction data from an instance of the model using the modelling data, at least one converter engine, a compositor to populate the converted data into a converted instance, and a compositor to populate the converted data into a converted instance.

First claim

The invention claimed is:

1. A system for building data exchange, comprising:
an information modelling unit, comprising a description of a digital twin, DT, model, a BIM, building information modelling, model and relations between the DT model and the BIM model, wherein the information modelling unit is configured to provide modelling data comprising information of the DT model, the BIM model and/or relations between the DT model and the BIM model;
a BIM extractor, being configured to determine extraction BIM data from a BIM instance of the BIM model of the building using the modelling data;
a DT extractor, being configured to determine extraction DT data from a DT instance of the DT model of the building using the modelling data;
at least one converter engine, being configured to convert the extraction DT data into converted DT data using the modelling data and being configured to convert the extraction BIM data into converted BIM data using the modelling data;
a BIM compositor, being configured to populate the converted DT data into a converted BIM instance using the modelling data; and
a DT compositor, being configured to populate the converted BIM data into a converted DT instance using the modelling data.

2. The system of claim 1 , further comprising:
a natural language processing, NLP, unit;
wherein the NLP unit is configured to extract additional BIM data from the BIM model and/or additional DT data from the DT model;
wherein the converter engine is configured to convert the extraction DT data and the additional DT data into converted DT data using the modelling data and being configured to convert the extraction BIM data and the additional BIM data into converted BIM data using the modelling data.

3. The system of claim 1 , wherein the converter engine is configured to model the relations between the DT model and the BIM model using the modelling data, wherein modelling the relations between the DT model and the BIM model comprise analysing the DT model and the BIM model and thereby determining a conversion method for converting at least part of the DT model into the BIM model and vice versa.

4. The system of claim 1 , wherein analysing the DT model and the BIM model comprises restructuring data of one of the DT model and the BIM model.

5. The system of claim 4 , wherein determining the conversion method comprises selecting a predetermined standard conversion method.

6. The system of claim 4 , wherein determining the conversion method comprises generating a modelling logic estimating a conversion between the DT model and the BIM model.

7. The system of claim 1 , wherein the information modelling unit uses a unified modelling language, UML, XML schemes, meta-models and/or ontologies to describes the DT, model, the BIM model, and/or the relations between the DT model and the BIM model.

8. The system of claim 1 , wherein the at least one converter engine is configured to identify errors in the provided extraction DT data and/or the provided extraction BIM data.

9. The system of claim 8 , wherein the identified error comprises wrong data or missing data in the provided extraction DT data and/or the provided extraction BIM data.

10. The system of claim 8 , wherein the at least one converter engine is configured to provide a suggestion to the identified error in the provided extraction DT data and/or the provided extraction BIM data using a knowledge database.

11. The system of claim 9 , wherein the provided extraction DT data and/or the provided extraction BIM data comprise a plurality of different data fields; wherein the NLP unit is configured to provide the suggestion to the identified error in a data field using data from another data field.

12. The system of claim 9 , wherein the NLP unit is configured to, when the converter engine identifies an error in the provided extraction DT data and/or the provided extraction BIM data, guide a user to correct the identified error.

13. The system of claim 9 , wherein the NLP unit is configured to provide a visualization of the identified error for the user.

14. A method for building data exchange, comprising:
determining, by a building information modelling, BIM, extractor, extraction BIM data from a BIM instance of a BIM model of the building using modelling data of an information modelling unit, comprising a description of a digital twin, DT, model, a BIM model and relations between the DT model and the BIM model, wherein the information modelling unit is configured to provide modelling data comprising information of the DT model, the BIM model and/or relations between the DT model and the BIM model;
converting, by a converter engine, the extraction BIM data into converted BIM data using the modelling data;
populating, by a DT compositor, the converted BIM data into a converted DT instance using the modelling data.

15. A method for building a data exchange, comprising:
determining, by a digital twin, DT, extractor, extraction DT data from a DT instance of a DT model of the building using the modelling data of an information modelling unit, comprising a description of the DT model, a BIM, building information modelling, model and relations between the DT model and the BIM model, wherein the information modelling unit is configured to provide modelling data comprising information of the DT model, the BIM model and/or relations between the DT model and the BIM model;
converting, by a converter engine, the extraction DT data into converted DT data using the modelling data;
populating, by a BIM compositor, the converted DT data into a converted BIM instance using the modelling data.
