Abstract

A method includes determining a first temperature of paving material, determining a first location of a paving machine corresponding to the first temperature, determining a second temperature of the paving material, and determining a second location of the paving machine corresponding to the second temperature. The method also includes generating a paving material map based at least partly on the first and second temperatures, and the first and second locations. The method further includes causing at least part of the paving material map to be displayed. The displayed at least part of the paving material map including visual indicia indicating the first temperature and the second temperature.

First claim

What is claimed is:

1. A method, comprising:
determining a first temperature of paving material at an auger assembly of a paving machine, the paving machine depositing the paving material on a paving surface;
determining a first location of the paving machine corresponding to the first temperature;
determining a second temperature of the paving material at the auger assembly;
determining a second location of the paving machine corresponding to the second temperature, wherein the second location is different from the first location;
generating a paving material map based at least partly on the first temperature, the first location, the second temperature, the second location, and timestamp information corresponding to at least one of the first temperature and the first location; and
causing at least part of the paving material map to be displayed via a control interface of the paving machine, the at least part of the paving material map displayed via the control interface including a first graphic, the first graphic including visual indicia indicating the first temperature and the second temperature.

2. The method of claim 1 , further comprising:
receiving the timestamp information, the timestamp information comprising first timestamp information corresponding to the first temperature, and second timestamp information corresponding to the first location; and
matching the first temperature and the first location based at least partly on the first timestamp information and the second timestamp information.

3. The method of claim 2 , further comprising generating the paving material map based at least partly on the first timestamp information, the second timestamp information, and third timestamp information corresponding to at least one of the second temperature and the second location.

4. The method of claim 1 , wherein the first temperature and the second temperature are determined by a first temperature sensor located proximate a first portion of the auger assembly on a first side of the paving machine, the method further comprising:
determining a third temperature of the paving material with an additional temperature sensor located proximate a second portion of the auger assembly, wherein the second portion is located on a second side of the paving machine opposite the first side, and the third temperature is determined simultaneously with the first temperature; and
determining a fourth temperature of the paving material with the additional temperature sensor and simultaneously with the second temperature, wherein the paving material map includes a second graphic, the second graphic including visual indicia indicating the third temperature and the fourth temperature.

5. The method of claim 4 , wherein the at least part of the paving material map displayed via the control interface includes the first graphic and the second graphic.

6. The method of claim 5 , wherein the at least part of the paving material map displayed via the control interface includes:
a third graphic including visual indicia indicating a fifth temperature of the paving material determined by the first temperature sensor at the first portion of the auger assembly, and a sixth temperature of the paving material determined by the first temperature sensor at the first portion of the auger assembly; and
a fourth graphic including visual indicia indicating a seventh temperature of the paving material determined by the additional temperature sensor at the second portion of the auger assembly, and an eighth temperature of the paving material determined by the additional temperature sensor at the second portion of the auger assembly, wherein
the first graphic is displayed adjacent to the second graphic,
the third graphic is displayed adjacent to the fourth graphic, and
the first graphic is displayed adjacent to the fourth graphic.

7. The method of claim 6 , wherein the fifth temperature is determined simultaneously with the seventh temperature, the sixth temperature is determined simultaneously with the eighth temperature, and the fifth temperature is determined after the fourth temperature.

8. The method of claim 1 , wherein the at least part of the paving material map displayed via the control interface includes visual indicia indicating a distance traveled by the paving machine between the first location and the second location.

9. The method of claim 1 , wherein the at least part of the paving material map is displayed via the control interface together with at least one of grade information indicating a grade of the paving material, and thickness information indicating a thickness of the paving material.

10. The method of claim 1 , wherein
the at least part of the paving material map is displayed via the control interface together with an input field, and
the controller is configured to cause haul truck ticket information to be displayed via the control interface at least partly in response to receiving an input via the input field.

11. A control system, comprising:
a communication device configured to determine a location of a paving machine;
a temperature sensor associated with the paving machine and configured to determine temperatures of paving material; and
a controller in communication with the communication device and the temperature sensor, the controller configured to:
receive a first signal from the temperature sensor, the first signal including first information indicative of a first temperature of the paving material,
receive a second signal from the communication device, the second signal including second information indicative of a first location of the paving machine corresponding to the first temperature,
receive a third signal from the temperature sensor, the third signal including third information indicative of a second temperature of the paving material,
receive a fourth signal from the communication device, the fourth signal including fourth information indicative of a second location of the paving machine corresponding to the second temperature,
generate a paving material map based at least partly on the first temperature, the first location, the second temperature, the second location, and timestamp information corresponding to at least one of the first temperature and the first location, and
cause at least part of the paving material map to be displayed via a control interface of the paving machine, the at least part of the paving material map displayed via the control interface including a first graphic, the first graphic including visual indicia indicating the first temperature and the second temperature.

12. The control system of claim 11 , wherein the temperature sensor comprises a first temperature sensor located proximate a first portion of an auger assembly on a first side of the paving machine, the control system further comprising an additional temperature sensor located proximate a second portion of the auger assembly on a second side of the paving machine opposite the first side, the additional temperature sensor being configured to determine temperatures of the paving material simultaneous with the first temperature sensor.

13. The control system of claim 11 , wherein generating the paving material map comprises:
matching the first temperature with the first location based at least partly on the timestamp information, wherein the timestamp information comprises first timestamp information included in the first signal and second timestamp information included in the second signal,
forming a first node corresponding to the first temperature and the first location, and
assigning a color to the first node based at least partly
