Abstract

A method includes receiving into a computer processor a building control subsystem design drawing, and identifying a plurality of objects in the building control subsystem design drawing by comparing the objects to a template of objects. The template of objects includes one or more of a representation of a shape, a color, and a texture. A physical relationship among the plurality of objects is determined, and a three dimensional representation of the plurality of objects is retrieved from a three dimensional device library. A three dimensional building control subsystem graphic is generated by mapping the three dimensional representation of the plurality of objects into a three dimensional user interface as a function of the physical relationship. The three dimensional user interface is animated and interactive to monitor and control a building subsystem.

Claims

1. A computerized method comprising:

receiving into a computer processor a two dimensional building control subsystem design drawing;

identifying with the computer processor a plurality of objects in the building control subsystem design drawing by comparing the objects to a template of objects, the template of objects comprising one or more of a representation of a shape, a color, and a texture;

determining with the computer processor a physical relationship among the plurality of objects;

retrieving into the computer processor a three dimensional representation of the plurality of objects from a three dimensional device library; and

generating with the computer processor a three dimensional building control subsystem graphic by mapping the three dimensional representation of the plurality of objects into a three dimensional user interface as a function of the physical relationship.

2. The computerized method of claim 1, comprising extracting one or more attributes of the object from the building control subsystem design drawing.

3. The computerized method of claim 1, wherein determining the physical relationship among the plurality of objects comprises using one or more of geometrical analysis and building control subsystem drawing conventions.

4. The computerized method of claim 1, wherein the three dimensional user interface is interactive.

5. The computerized method of claim 1, wherein the plurality of objects comprise one or more of mechanical equipment, electrical equipment, and a connection between mechanical equipment and electrical equipment.

6. The computerized method of claim 1, wherein the three dimensional representation comprises one or more of a web page, a script, or other publication technology.

7. The computerized method of claim 1, wherein the identifying a plurality of objects in the building control subsystem design drawing comprises extracting a boundary of the objects and analyzing a relationship among the objects.

8. The computerized method of claim 1, wherein the three dimensional representation of the plurality of objects comprises an object-oriented data model.

9. The computerized method of claim 1, comprising extracting text associated with an object on the building control subsystem design drawing by way of a character recognition process.

10. The computerized method of claim 1, comprising animating an object on the three dimensional building control subsystem graphic.

11. The computerized method of claim 1, wherein the three dimensional representation of the plurality of objects is directly linked to data produced by a real-time control system, and wherein the three dimensional representation of the plurality of objects is responsive and adaptive to data provided by one or more of the real-time control system and a data source separate from the real-time control system.

12. A non-tangible computer readable medium comprising instructions that when executed by a computer processor execute a process comprising:

receiving a building control subsystem design drawing;

identifying a plurality of objects in the building control subsystem design drawing by comparing the objects to a template of objects, the template of objects comprising one or more of a representation of a shape, a color, and a texture;

determining a physical relationship among the plurality of objects;

retrieving a three dimensional representation of the plurality of objects from a three dimensional device library; and

generating a three dimensional building control subsystem graphic by mapping the three dimensional representation of the plurality of objects into a three dimensional user interface as a function of the physical relationship.

13. The non-tangible computer readable medium of claim 12, comprising instructions for extracting one or more attributes of the object from the building control subsystem design drawing.

14. The non-tangible computer readable medium of claim 12, wherein determining the physical relationship among the plurality of objects comprises using one or more of geometrical analysis and building control subsystem drawing conventions.

15. The non-tang computer readable medium of claim 12, wherein the plurality of objects comprise one or more of mechanical equipment, electrical equipment, and a connection between the mechanical equipment and the electrical equipment.

16. The non-tangible computer readable medium of claim 12, wherein the identifying a plurality of objects in the building control subsystem design drawing comprises extracting a boundary of the objects and analyzing a relationship among the objects.

17. The non-tangible computer readable medium of claim 12, wherein the three dimensional representation of the plurality of objects comprises an object-oriented data model.

18. The non-tangible computer readable medium of claim 12, comprising instructions for extracting text associated with an object on the building control subsystem design drawing by way of a character recognition process.

19. The non-tangible computer readable medium of claim 12, comprising instructions for animating an object on the three dimensional building control subsystem graphic.

20. The non-tangible computer readable medium of claim 12, wherein the three dimensional representation of the plurality of objects is directly linked to data produced by a real-time control system, and wherein the three dimensional representation of the plurality of objects is responsive and adaptive to data provided by one or more of the real-time control system and a data source separate from the real-time control system.
