Abstract

A hook block sensor assembly is disclosed. In one embodiment, the hook block sensor comprises a housing configured to removably couple about a lifting hook of a lifting device, a first global navigation satellite system (GNSS) receiver coupled with the housing and configured for determining a hook block sensor assembly position in three dimensions, a load monitor coupled with the housing and configured for monitoring a load coupled with the lifting hook, including monitoring a load position and a load orientation of the load and a wireless transceiver coupled with the housing and configured for wirelessly providing information including the load position, the load orientation, and the hook block sensor assembly position, to a display unit located apart from the hook block sensor assembly.

Claims

1. A hook block sensor assembly comprising:

a housing configured to removably couple about a lifting hook of a lifting device;

a first global navigation satellite system (GNSS) receiver coupled with said housing and configured for determining a hook block sensor assembly position in three dimensions;

a load monitor coupled with said housing and configured for monitoring a load coupled with said lifting hook, including monitoring a load position and a load orientation of said load; and

a wireless transceiver coupled with said housing and configured for wirelessly providing information including said load position, said load orientation, and said hook block sensor assembly position, to a display unit located apart from said hook block sensor assembly.

2. The hook block sensor assembly of claim 1, further comprising:

a second GNSS receiver coupled with said housing and configured for determining an angular orientation of said hook block sensor assembly.

3. The hook block sensor assembly of claim 1, further comprising:

a collision monitor coupled with said housing and configured monitoring for collision related hazards in a vicinity of said lifting hook.

4. The hook block sensor assembly of claim 3, further comprising:

an avoidance action initiator coupled with said housing configured for initiating at least one hazard avoidance action in response to a monitored occurrence of said collision related hazard.

5. The hook block sensor assembly of claim 1, further comprising:

a power source coupled with said housing and configured for providing electrical power for operating electrical components of said hook block sensor assembly.

6. The hook block sensor assembly of claim 5, further comprising:

a power source charger coupled with said housing and configured for generating a charge for charging said power source.

7. The hook block sensor assembly of claim 1, further comprising:

a protective bumper disposed on a portion of an external surface of said housing.

8. The hook block sensor assembly of claim 1, further comprising:

a lift plan generator coupled with said housing and configured for generating a lift plan for lifting said load to a destination associated with said load.

9. The hook block sensor assembly of claim 1, wherein said load monitor is selected from the group of a camera, a plurality of cameras, an ultrasonic sensor, a laser scanner, a bar code scanner, a radio frequency identification device transceiver, and an inertial sensor.

10. The hook block sensor assembly of claim 1, wherein said load monitor is further configured for monitoring for load related hazards in a vicinity of said load.

11. The hook block sensor assembly of claim 1, wherein said load monitor is configured for monitoring for one or more object identifiers coupled with said load or one or more other objects in a field of view of said load monitor from said hook block sensor assembly.

12. The hook block sensor assembly of claim 1, wherein said transceiver is further configured for wirelessly communicating with a second sensor unit coupled with a second lifting device.

13. The hook block sensor assembly of claim 1, wherein said transceiver is further configured for accessing load cell information of said lifting device, said load cell information indicative of said lifting device taking or releasing said load with said lifting hook.

14. The hook block sensor assembly of claim 1, wherein said housing includes a power source access hatch for accessing a power source of said hook block sensor assembly while said hook block sensor assembly is coupled with said lifting hook.

15. The hook block sensor assembly of claim 14, wherein said housing includes recharge contacts, said recharge contacts accessible for recharging said power source of said hook block sensor assembly while said hook block sensor assembly is coupled with said lifting hook.

16. The hook block sensor assembly of claim 1, wherein at least a portion of said housing is radio frequency transparent to GNSS signals for facilitating receipt of said GNSS signals by said first GNSS receiver.

17. The hook block sensor assembly of claim 1, wherein said housing comprises at least two portions configured for removably coupling with one another about said lifting hook.
