Object tracking method and system
A system for tracking at least one object configured to be transported by at least one vehicle may include at least one computer system. The at least one computer system may be configured to determine at least one location of the at least one vehicle and determine at least one location of the at least one object. The at least one computer system may be further configured to determine at least one location of at least one geofence adjacent the at least one vehicle based on the at least one location of the at least one vehicle. Also, the at least one computer system may be configured to determine whether the at least one object is located within the at least one geofence to determine whether a load of the at least one vehicle includes the at least one object.
1. An object tracking system, comprising:
a first wireless device associated with an object;
a second wireless device associated with an object transport vehicle; and
a controller configured to:
determine a location of the object based on a first signal associated with the first wireless device;
generate a geofence surrounding at least a portion of the object transport vehicle based on a second signal associated with the second wireless device;
determine a position of the object relative to the geofence based on the determined location of the object; and
provide an indication that the object has been loaded on the object transport vehicle when the object is located within the geofence.
2. The object tracking system of claim 1 , wherein the first wireless device is a tag.
3. The object tracking system of claim 2 , further including an interrogator configured to read the tag and generate the first signal.
4. The object tracking system of claim 1 , wherein the first wireless device is a position sensor configured to generate the first signal.
5. The object tracking system of claim 1 , wherein the second wireless device is a tag.
6. The object tracking system of claim 1 , wherein the second wireless device is a position sensor.
7. The object tracking system of claim 1 , wherein the controller is configured to generate the geofence based on at least one characteristic associated with the object transport vehicle.
8. The object tracking system of claim 1 , wherein the controller is configured to receive information associated with the geofence from the object transport vehicle.
9. The object tracking system of claim 8 , wherein the object transport vehicle includes a control system configured to generate the information associated with the geofence.
10. The object tracking system of claim 9 , wherein the controller is configured to determine whether the object has been loaded onto the object transport vehicle based on the weight.
11. The object tracking system of claim 1 , wherein the controller is configured to receive a weight of a load transported by the object transport vehicle.
12. The object tracking system of claim 11 , wherein the controller is configured to modify a size of the geofence when the weight is greater than a threshold and the controller determines that the object is not within the geofence.
13. The object tracking system of claim 1 , wherein a size of the geofence is based on at least one of a pallet size associated with the object transport vehicle or at least one characteristic of at least one load carried by the object transport vehicle.
14. The object tracking system of claim 1 , wherein the controller is further configured to:
modify a size of the geofence to a new size; and
provide the new size to the object transport vehicle.
15. A method for tracking an object configured to be transported by an object transport vehicle, the method comprising:
receiving, using a controller, first data from a first wireless device associated with the object;
determining a location of the object based on the first data;
receiving, using the controller, second data from a second wireless device associated with the object transport vehicle;
generating a geofence surrounding at least a portion of the object transport vehicle based on the second data; and
determining a position of the object relative to the geofence to determine whether the object has been loaded on the object transport vehicle.
16. The method of claim 15 , wherein the first wireless device is a position sensor and determining the location of the object includes extracting the location from the received first data.
17. The method of claim 15 , wherein the second data includes information indicative of a size of the geofence.
18. The method of claim 15 , wherein the second wireless device is a position sensor, and generating the geofence includes:
determining a location of the object transport vehicle based on the second data;
generating the geofence based on the determined location of the object transport vehicle and at least one characteristic of the object transport vehicle.
19. The method of claim 15 , wherein
the first wireless device is a tag,
receiving the first data includes reading the tag with a reader, and
determining the location includes receiving the location of the object from the reader.
20. The method of claim 15 , wherein
the second wireless device is a tag, and
generating the geofence includes:
reading information associated with the tag with a reader,
determining a location of the object transport vehicle based on the information, and
determining the location of the geofence based on the determined location of the object transport vehicle.
