Abstract

A device and method of communicating the temperature of paving material on a surface, including receiving temperature and position information of a portion of the paving material, determining a plurality of predicted temperatures of the paving material each associated with a plurality of positions of the paving material with a temperature and positional model, and displaying the plurality of predicted temperatures of the paving material at the plurality of positions of the paving material with respect to at least one machine.

First claim

We claim:

1. An operator interface, comprising:
a transceiver configured to receive temperature and position information of a portion of a paving material from one or more sensors;
a processor in communication with the transceiver and configured to determine a plurality of predicted temperatures associated with a plurality of positions of the paving material based on the temperature and position information and a temperature and positional model that is defined by a cooling curve; and
a display device in communication with the processor and configured to display a graphical user interface configured to receive operator input, convert the plurality of predicted temperatures of the paving material at the plurality of positions of the paving material into a map within the graphical user interface displaying a plurality of different temperature zones spatially positioned relative to at least one machine, and identify at least one operational function of the at least one machine to be locked out in at least one of the temperature zones.

2. The operator interface of claim 1 , wherein the transceiver is configured to receive the temperature and position information of the portion of the paving material from one or more temperature sensors that are mounted on the at least one machine.

3. The operator interface of claim 1 , wherein the transceiver is configured to receive the temperature information from a temperature sensor configured to determine a temperature of the paving material at a particular location, and receive the position information from a position sensor configured to determine a position of the particular location.

4. The operator interface of claim 1 , further comprising a memory in communication with the processor and configured to retrievably store one or more temperature and positional models accessible by the processor, each of the temperature and positional models being defined at least partially based on a cooling curve associated with the paving material.

5. The operator interface of claim 4 , wherein the processor is configured to retrieve the temperature and positional model from the memory.

6. The operator interface of claim 1 , further comprising one or more input devices configured to receive operator input, the display device being configured to adjust the map displayed within the graphical user interface in response to the operator input.

7. The operator interface of claim 1 , wherein the plurality of different temperature zones include a tender zone, a compaction zone, and a cold zone.

8. The operator interface of claim 7 , wherein the tender zone is represented on the display by a first color filling the space between a starting location and an end location of the tender zone, and wherein the cold zone is represented on the display by a second color filling the space between the starting location and the end location of the cold zone.

9. The operator interface of claim 7 , wherein the temperature and positional model is based in part on one or more of an ambient temperature, a wind speed, weather, humidity, paving material type, and a moisture level.

10. The operator interface of claim 7 , wherein the display device is configured to identify that a compacting operational function is locked out in the tender zone and the cold zone.

11. A method of determining and displaying predicted temperatures of paving material on an operator interface, the method comprising:
receiving, at a transceiver, temperature and position information of a portion of the paving material from one or more sensors;
determining, at a processor, at least one temperature and positional model based on a cooling curve;
determining, at the processor, a plurality of predicted temperatures of the paving material each associated with a plurality of positions of the paving material based on the temperature and positional model and the temperature and position information;
displaying, at a display device, a graphical user interface configured to receive operator input;
converting, at the display device, the plurality of predicted temperatures of the paving material at the plurality of positions of the paving material into a map within the graphical user interface displaying a plurality of different temperature zones spatially positioned relative to at least one machine; and
identifying, at the display device, at least one operational function of the at least one machine to be locked out in at least one of the temperature zones.

12. The method of claim 11 , wherein the temperature and position information of the portion of the paving material is received from one or more temperature sensors that are mounted on the at least one machine.

13. The method of claim 11 , wherein the temperature information is received from a temperature sensor configured to determine a temperature of paving material at a particular location, and the position information is received from a position sensor configured to determine a position of the particular location.

14. The method of claim 11 , further comprising updating the temperature and positional model based on the temperature and position information received.

15. The method of claim 11 , wherein the temperature and positional model is retrieved from a memory storing a plurality of temperature and positional models each being defined based on different cooling curves associated with the paving material.

16. The method of claim 11 , wherein the plurality of predicted temperatures include a tender zone, a compaction zone, and a cold zone.

17. The method of claim 16 , wherein the tender zone is represented on the display by a first color filling the space between a starting location and an end location of the tender zone, and wherein the cold zone is represented on the display by a second color filling the space between the starting location and the end location of the cold zone.

18. The method of claim 16 , wherein the temperature and positional model is based in part on one or more of an ambient temperature, a wind speed, weather, humidity, paving material type, and a moisture level.

19. The method of claim 16 , wherein a compacting operational function is identified as being locked out in the tender zone and the cold zone.

20. A compactor, comprising:
a front ground engaging member;
a rear ground engaging member;
a power source to drive at least one of the ground engaging members; and
an operator interface configured to determine and display a predicted temperature of a paving material at a plurality of positions, the operator interface comprising:
a transceiver configured to receive temperature and position information of a portion of the paving material;
a processor in communication with the transceiver and configured to determine a plurality of predicted temperatures associated with a plurality of positions of the paving material based on a temperature and positional model and the temperature and position information; and
a display device in communication with the processor and configured to display a graphical user interface configured to receive operator input, convert the plurality of predicted temperatures of the paving material at the plurality of positions of the paving material into a map within the graphical user interface displaying a plurality of different temperature zones spatially positioned relative to at least one machine, and identify at least one operational function of the at least one machine to be locked out in at least one of the temperature zones.
