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. A system, comprising:
a first sensor configured to determine a vehicle location;
a second sensor configured to determine an object location; and
a controller configured to:
receive the vehicle location from the first sensor;
receive the object location from the second sensor;
transmit the vehicle location to a corresponding vehicle;
receive, from the vehicle, information reflecting a geofence surrounding at least a portion of the vehicle, the geofence being determined based on at least the vehicle location;
determine whether an object corresponding to the object location is located within the geofence based at least on the information reflecting the geofence and the object location;
generate a signal indicating that the object has been loaded on the vehicle when the object is determined to be located within the geofence; and
cause a display in the vehicle to display information reflecting the signal.
2. The system of claim 1 , wherein the vehicle is configured to generate the geofence based on at least one characteristic associated with the vehicle.
3. The system of claim 1 , further including a weight sensor configured to determine a weight of a load transported by the vehicle.
4. The system of claim 3 , wherein the controller is further configured to:
receive the weight of the load from the weight sensor; and
determine whether the object is located within the geofence based on the object location and the weight.
5. The system of claim 4 , wherein the controller is configured to modify a size of the geofence to a new size when the weight is greater than a threshold weight and the object is not located within the geofence.
6. The system of claim 5 , wherein the controller is configured to receive an input from a user to define the threshold weight.
7. The system of claim 5 , wherein the controller is further configured to transmit the new size to the object transport vehicle.
8. The system of claim 1 , wherein a size of the geofence is based on at least one of a pallet size associated with the vehicle or at least one characteristic of at least one load carried by the vehicle.
9. The system of claim 1 , wherein the display is configured to display a destination of the object.
10. The system of claim 1 ,
wherein the vehicle includes a direction sensor configured to determine a direction of travel of the object transport vehicle, and
wherein the geofence is determined based on both the vehicle location and the direction of travel.
11. The system of claim 1 , wherein the vehicle is configured to generate the geofence by:
determining a center point of the vehicle;
positioning a center of the geofence at a predetermined distance from the center point along a longitudinal axis of the vehicle;
positioning the geofence symmetrically about the center point of the vehicle and the center of the geofence.
12. The system of claim 1 , wherein the first sensor is a global positioning system (GPS) device.
13. The system of claim 1 , wherein the second sensor is a wireless tag.
14. The system of claim 13 , further including an interrogator configured to read information from the tag.
15. The system of claim 14 , wherein the controller is configured to determine the location of an object based on the information from the tag.
16. The system of claim 14 , wherein the controller is configured to determine the location of the object based on the information from the tag and a location of the interrogator.
17. A vehicle configured to transport an object, the vehicle including:
a position sensor configured to determine a vehicle location of the vehicle;
a controller configured to:
receive, from a worksite computer separated from the vehicle, an object location indicating a position of the object;
generate a geofence associated with the vehicle based on at least the vehicle location; and
receive, from the worksite computer, a signal indicating that the object has been loaded on the vehicle; and
a display configured to display the vehicle location, the geofence, and the indication.
18. The vehicle of claim 17 , wherein the controller is configured to generate the geofence based on the vehicle location and at least one characteristic of the vehicle.
19. The vehicle of claim 18 , wherein the at least one characteristic includes at least one of a length of the vehicle, a width of the vehicle, a pallet size of the vehicle, or a size or location of an object being carried by the vehicle.
20. The vehicle of claim 18 , further including a direction sensor, and wherein the controller is further configured to:
determine, using the direction sensor, a direction of travel of the vehicle; and
position the center of the geofence around the vehicle based on the direction of travel.
