Abstract

Methods and systems are disclosed for identifying and locating an object in an environment. Identification data for an object is received from an identity sensor, the data received at a central computer system. Location data is received from a lifting device at the central computer system. Load data is received at the central computer system that the object has been loaded onto the lifting device. A location of the object is tracked based on the identification data, the location data, and the load data for the object at the central computer system.

Claims

1. A method for identifying and locating an object in an environment, said method comprising:

receiving identification data for an object from an identity sensor, said data received at a central computer system;

receiving location data from a lifting device at said central computer system;

receiving load data at said central computer system that said object has been loaded onto said lifting device; and

tracking a location of said object based on said identification data, said location data, and said load data for said object at said central computer system.

2. The method as recited in claim 1 wherein said lifting device is a crane wherein said crane is selected from the group of cranes consisting of:

a tower crane, a luffing crane, a level luffing crane, a fixed crane, a mobile crane, a self-erecting crane, a crawler crane, and a telescopic crane.

3. The method as recited in claim 1 wherein said lifting device is a forklift.

4. The method as recited in claim 1 wherein said identifying sensor is a radio frequency identification (RFID) detector associated with said lifting device that automatically reads an RFID chip coupled with said object once said object is loaded onto said lifting device.

5. The method as recited in claim 1 wherein said identifying sensor is a handheld device associated with a rigger.

6. The method as recited in claim 5 wherein said handheld device generates said identification data by scanning a bar code on said object.

7. The method as recited in claim 5 wherein said handheld device generates said identification data by reading radio frequency identification (RFID) associated with said object.

8. The method as recited in claim 5 wherein said handheld device receives said identification data from a rigger using said handheld device.

9. The method as recited in claim 1, further comprising:

associating characteristic data for said object with said location data for said object.

10. The method as recited in claim 9 wherein said characteristic data for said object is retrieved by said central computer system from a building information modeling (BIM) system.

11. The method as recited in claim 1 wherein said central computer system comprises a building information modeling (BIM) system.

12. The method as recited in claim 1 wherein said location data is generated by a global navigation satellite system (GNSS) antenna and receiver associated with said lifting device.

13. The method as recited in claim 1 wherein a location of said lifting device is known to said central computer system.

14. The method as recited in claim 1 wherein said location data is a location of said object when said object is loaded onto said lifting device.

15. The method as recited in claim 1 wherein said location data is a location of said object after said object is unloaded from said lifting device.

16. The method as recited in claim 1 wherein said lifting device comprises a plurality of location generating devices for generating said location data.

17. The method as recited in claim 1 wherein said location data is generated by mechanical sensors associated with lifting device.

18. The method as recited in claim 1 wherein said location data is for an absolute coordinate system.

19. The method as recited in claim 1 wherein said location data is for a local coordinate system.

20. The method as recited in claim 1 wherein said central computer system updates a lift plan for said lifting device based on said identification data, said location data, and said load data for said object.

21. A computer-usable storage medium having instructions embodied therein that when executed cause a computer system to perform a method for identifying and locating an object in an environment, said method comprising:

receiving identification data for an object from an identity sensor, said data received at a central computer system;

receiving location data from a lifting device at said central computer system;

receiving load data at said central computer system that said object has been loaded onto said lifting device; and

tracking a location of said object based on said identification data, said location data, and said load data for said object at said central computer system.

22. The computer-usable storage medium as recited in claim 21, wherein said identity sensor is a radio frequency identification (RFID) detector associated with said lifting device that automatically reads an RFID chip coupled with said object once said object is loaded onto said lifting device.

23. The computer-usable storage medium as recited in claim 21, wherein said identity sensor is a handheld device associated with a rigger.

24. The computer-usable storage medium as recited in claim 23, wherein said handheld device receives said identification data from a rigger using said handheld device.

25. The computer-usable storage medium as recited in claim 21, wherein said location data is generated by a global navigation satellite system (GNSS) antenna and receiver associated with said lifting device.

26. The computer-usable storage medium as recited in claim 21, wherein said location data is generated by mechanical sensors associated with lifting device.

27. The computer-usable storage medium as recited in claim 21, wherein said central computer system updates a lift plan for said lifting device based on said identification data, said location data, and said load data for said object.

28. A system for identifying and locating an object in an environment, said system comprising:

an object in an environment wherein said object is to be moved by a lifting device; and

a central computer system for receiving identification data, location data, and load data for said object and for tracking a location of said object based on said identification data, said location data, and said load data for said object.

29. The system as recited in claim 28 further comprising:

a handheld device for generating said identification data, wherein said identification data identifies said object.

30. The system as recited in claim 29 wherein said handheld device employs a radio frequency identification (RFID) detector to identify said object.

31. The system as recited in claim 29 wherein said handheld device employs a bar code reader to identify said object.

32. The system as recited in claim 28 further comprising:

said lifting device comprising;

at least one location sensor for generating said location data indicating a location of said object; and

a load sensor for generating said load data indicating that said object has been loaded onto said lifting device.

33. The system as recited in claim 32 wherein said at least one location sensor is a global navigation satellite system (GNSS) antenna.

34. The system as recited in claim 32 wherein said at least one location sensor is a mechanical sensor.

35. The system as recited in claim 28 wherein said lifting device is a crane wherein said crane is selected from the group of cranes consisting of:

a tower crane, a luffing crane, a level luffing crane, a fixed crane, a mobile crane, a self-erecting crane, a crawler crane, and a telescopic crane.
