Abstract
A position tracking system includes one or more beacons and one or more sensor pairs. Each of the one or more sensor pairs is configured to be disposed on equipment that moves within a facility. Each of the one or more sensor pairs includes a motion sensor and a beacon sensor configured to receive signals from the one or more beacons. The position tracking system also include a control system, which include a processor configured to receive a first signal collected by the motion sensor, receive a second signal collected by the beacon sensor, compute a first location and/or orientation based on the first signal, and determine a second location and/or orientation based on the second signal.
Claims16
A position tracking system, comprising:
- one or more beacons;
- one or more sensor pairs, wherein each of the one or more sensor pairs is configured to be disposed on equipment that moves within a facility, and wherein each of the one or more sensor pairs comprises a motion sensor and a beacon sensor configured to receive signals from the one or more beacons;
- and
- a control system, comprising a processor configured to:
- receive a first signal collected by the motion sensor;
- receive a second signal collected by the beacon sensor;
- compute a first location of the equipment based on the first signal;
- determine a second location of the equipment based on the second signal;
- calibrate the motion sensor based on the determined second location;
- and
- wherein one or more beacons transmit their location coordinates via a transmitter to the beacon sensor as the equipment comes into a receiving field-of-view of the respective beacon and the second signal received by the processor includes the location coordinates.
A position tracking system, comprising:
- one or more beacons disposed within a facility;
- one or more sensor pairs, wherein each of the one or more sensor pairs is disposed on equipment that moves within the facility, and wherein each of the one or more sensor pairs comprises a motion sensor and a beacon sensor configured to receive signals from the one or more beacons;
- and
- a control system, comprising:
- a memory;
- and
- a processor configured to execute instructions stored on the memory comprising instructions for:
- receiving a first signal collected by the motion sensor;
- receiving a second signal collected by the beacon sensor;
- computing a first location of the equipment based on the first signal;
- determining a second location of the equipment based on the second signal;
- calibrating the motion sensor based on the determined second location;
- and
- wherein one or more beacons transmit their location coordinates via a transmitter to the beacon sensor as the equipment comes into a receiving field-of-view of the respective beacon and the second signal received by the processor includes the location coordinates.
A method for providing positioning of equipment comprising:
- receiving a first signal collected by a motion sensor coupled to the equipment;
- receiving a second signal collected by a beacon sensor coupled to the equipment, wherein the second signal is collected when the beacon sensor is within a field-of-view of a beacon and the second signal includes location coordinate of the respective beacon transmitted by a transmitter of the beacon;
- computing a first location of the equipment based on the first signal;
- determining a second location of the equipment based on the second signal;
- calibrating the motion sensor based on the determined second location.
