Abstract

A method and system of verifying asphalt mat temperature values and location data generated by a paving machine includes identifying a location and temperature value of a threshold thermal characteristic of thermal data generated by the paving machine, and displaying the paver-generated location and temperature value of the threshold thermal characteristic on a display of the paving machine. The method further includes determining a location and temperature value of the threshold thermal characteristic by one or more external systems, and comparing the externally-determined location and temperature value to the paver-generated location and temperature value.

First claim

What is claimed is:

1. A paving machine, comprising:
a thermal recognition system of the paving machine that creates thermal data of an area behind the paving machine, wherein the thermal recognition system is configured to create the thermal data of the area behind the paving machine while the paving machine is not performing a paving operation;
a position determining system that identifies a location of the thermal data in location coordinates;
a display that displays the location and temperature of a threshold thermal characteristic of the thermal data, and
a controller that receives the thermal data and location data and determines the location and temperature of the threshold thermal characteristic, wherein the controller is configured to identify one or more thermal objects that include the threshold thermal characteristic compared to a surrounding environment located behind the paving machine,
wherein the location and temperature of the threshold thermal characteristic of the one or more thermal objects is displayed when the paving machine is not performing the paving operation, and
wherein the controller is further configured to:
receive location and temperature values of the thermal object determined by one or more external systems; and
compare the location and temperature values determined by the one or more external systems to the location and temperature values generated by the thermal recognition system of the paving machine.

2. The paving machine of claim 1 , wherein the threshold thermal characteristic of the one or more thermal objects is a maximum temperature characteristic of the thermal data that is hotter than the surrounding environment.

3. The paving machine of claim 1 , wherein the thermal recognition system is a thermal imaging camera, and the thermal data is thermal image data.

4. The paving machine of claim 3 , wherein the area behind the paving machine corresponds to a viewing area of the thermal imaging camera.

5. The paving machine of claim 1 , wherein the threshold thermal characteristic includes a plurality of locations of the thermal data.

6. The paving machine of claim 1 , wherein the position determining system includes a GPS system.

7. The paving machine of claim 1 , wherein the location and temperature of the threshold thermal characteristic is displayed on a same page of the display, and no other temperatures or location information is displayed on the same page.

8. The paving machine of claim 1 , wherein the location and temperature of the threshold thermal characteristic is displayed in real time.

9. A method of verifying asphalt mat temperature values and location data generated by a paving machine, comprising:
identifying a location and temperature values of a threshold or identifiable thermal characteristic of thermal data generated by the paving machine with a thermal recognition system, wherein the threshold or identifiable thermal characteristic corresponds to one or more thermal objects that include the threshold thermal or identifiable characteristic compared to a surrounding environment located behind the paving machine, wherein the thermal recognition system creates the thermal data of the surrounding environment located behind the paving machine while the paving machine is not performing a paving operation;
displaying the location and temperature values of the threshold or identifiable thermal characteristic generated by the paving machine on a display of the paving machine, wherein the location and temperature of the threshold or identifiable thermal characteristic of the one or more thermal objects is displayed when the paving machine is not performing the paving operation;
determining location and temperature values of the threshold or identifiable thermal characteristic by one or more external systems;
identifying the location of the one or more thermal objects based on the determined location and temperature values of the threshold or identifiable thermal characteristic by the one or more external systems; and
comparing the determined location and temperature values of the threshold or identifiable thermal characteristic by the one or more external systems to the location and temperature values of the threshold or identifiable thermal characteristic generated by the paving machine.

10. The method of claim 9 , wherein the threshold or identifiable temperature characteristic corresponds to one thermal object located behind the paving machine.

11. The method of claim 9 , wherein the threshold or identifiable thermal characteristic includes a plurality of thermal objects located behind the paving machine.

12. The method of claim 9 , wherein the one or more external systems includes an external locating device and an external thermal sensor.

13. The method of claim 9 , wherein the thermal recognition system is a thermal imaging camera, the thermal data is thermal image data; and the location generated by the paving machine is based on a GPS system of the paving machine.

14. The method of claim 9 , wherein the location and temperature values generated by the paving machine are displayed on a same page of the display, and no other temperatures or location information is displayed on the same page.

15. The method of claim 9 , wherein the location and temperature of the threshold or identifiable thermal characteristic is displayed in real time.

16. A method of verifying asphalt mat temperature values and location data generated by a paving machine, comprising:
identifying location and temperature values of a thermal object that include a threshold or identifiable thermal characteristic compared to a surrounding environment using a thermal recognition system of the paving machine and a position determining system of the paving machine, wherein the thermal recognition system creates thermal data of the surrounding environment while the paving machine is not performing a paving operation;
displaying the location and temperature values of the thermal object generated by the paving machine on a display of the paving machine, wherein the location and temperature of the threshold thermal characteristic of the thermal object is displayed when the paving machine is not performing the paving operation;
determining location and temperature values of the thermal object by one or more external systems; and
comparing the location and temperature values determined by the one or more external systems to the location and temperature values generated by the paving machine.

17. The method of claim 16 , wherein the displaying of the location and temperature values generated by the paving machine are displayed on a same page of the display, and no other temperatures or location information is displayed on the same page.
