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, wherein
the first temperature is determined proximate an assembly of a paving machine,
the paving machine is configured to deposit the paving material onto a paving surface, and
the first temperature is determined while the paving machine is disposed at a first location;

determining the first location of the paving machine;
determining a second temperature of the paving material, wherein
the second temperature is determined proximate the assembly, and
the second temperature is determined while the paving machine is disposed at a second location different from the first location;

determining the second location of the paving machine; and
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.

2. The method of claim 1 , wherein the paving material map is generated based at least in part on second timestamp information corresponding to at least one of the second temperature and the second location.

3. The method of claim 1 , wherein the first temperature and the second temperature are determined proximate to the assembly and downstream of a conveyor system, the conveyor system comprising a system of the paving machine configured to transport the paving material from a hopper of the paving machine to the assembly of the paving machine.

4. The method of claim 3 , wherein the assembly of the paving machine comprises an auger assembly that receives the paving material from the conveyor system and deposits the paving material onto the paving surface ahead of a screed portion of the paving machine.

5. The method of claim 1 , further comprising:
determining a ground temperature of the paving surface before the paving material is deposited onto the paving surface; and
generating the paving material map based at least partly on the ground temperature.

6. The method of claim 1 , further comprising:
determining an ambient temperature at a third location proximate the paving machine; and
generating the paving material map based at least partly on the ambient temperature.

7. The method of claim 1 , wherein the assembly is proximate to a first side of the paving machine, the method further comprising:
determining, substantially simultaneously with determining the first temperature, a third temperature of the paving material proximate a second assembly of the paving machine, the second assembly being proximate to a second side of the paving machine that is opposite the first side; and
generating the paving material map based further on the third temperature.

8. The method of claim 1 , wherein the paving material map indicates temperatures of the paving material deposited on the paving surface at a plurality of locations along a path traveled by the paving machine.

9. The method of claim 1 , further comprising transmitting the paving material map, via a network, to at least one of a mobile device or a computing device that is remote from the paving machine.

10. A control system, comprising:
a communication device configured to determine a location of a paving machine configured to deposit paving material onto a paving surface;
a temperature sensor positioned on the paving machine proximate to an assembly of the paving machine; 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 determined while the paving machine is disposed at a first location;
receive a second signal from the communication device, the second signal including second information indicative of the first location of the paving machine;
receive a third signal from the temperature sensor, the third signal including third information indicative of a second temperature of the paving material determined while the paving machine is disposed at a second location different from the first location;
receive a fourth signal from the communication device, the fourth signal including fourth information indicative of the second location of the paving machine; and
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.

11. The control system of claim 10 , wherein the temperature sensor is positioned proximate to the assembly and downstream of a conveyor system of the paving machine, the conveyor system comprising a system of the paving machine configured to transport the paving material from a hopper of the paving machine to the assembly of the paving machine.

12. The control system of claim 10 , further comprising a ground temperature sensor, wherein the controller is further configured to:
receive a fifth signal from the ground temperature sensor, the fifth signal including fifth information indicative of a ground temperature of the paving surface before the paving material is deposited onto the paving surface; and
generate the paving material map based at least partly on the ground temperature.

13. The control system of claim 10 , further comprising an ambient temperature sensor, wherein the controller is further configured to:
receive a fifth signal from the ambient temperature sensor, the fifth signal including fifth information indicative of an ambient temperature; and
generate the paving material map based further on the ambient temperature.

14. The control system of claim 10 , further comprising:
a second temperature sensor positioned on the paving machine proximate to a second assembly of the paving machine,
wherein the assembly is proximate to a first side of the paving machine and the second assembly is proximate to a second side of the paving machine that is opposite to the first side, and
wherein the controller is further configured to:
receive a fifth signal from the second temperature sensor, the fifth signal including fifth information indicative of a third temperature of the paving material, the third temperature being determined substantially simultaneously with a determination of the first temperature; and
generate the paving material map based further on the third temperature.

15. The control system of claim 10 , wherein the controller is further configured to transmit the paving material map to at least one of a mobile device or a computing device that is remote from the paving machine.

16. A paving machine comprising:
a hopper adapted to receive paving material;
an assembly adapted to deposit the paving material onto a paving surface;
a conveyor system adapted to convey the paving material from the hopper to the assembly;
a temperature sensor positioned proximate to the assembly, the temperature sensor adapted to determine temperatures of the paving material;
a communication device configured to determine a location of the paving machine; and
a controller in communication with the temperature sensor and the communication device, 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 determined while the paving machine is disposed at a first location;
receive a sec
