Abstract

A method for determining and monitoring output of a milling machine comprises sensing an operating parameter of a milling machine with a sensor, transmitting data from the sensor of the milling machine to an off-board location, determining a performance parameter of the milling machine from the data at the off-board location, transmitting the performance parameter to the milling machine, and displaying the performance parameter on a display screen of the milling machine.

First claim

What is claimed is:

1. A system for determining and monitoring output of a milling machine, the system comprising:
a cutting system having a cutting tool extending across a cutting path about a rotational axis;
a sensor positioned on the milling machine to sense a performance parameter of the cutting tool and generate raw sensor data;
a communication device electronically coupled to the sensor to receive the raw sensor data and transmit the raw sensor data to a remote location physically separate from and outside of the milling machine via a wireless communication signal; and
a monitoring device located apart from and physically separated from the milling machine at the remote location, the monitoring device configured to receive the wireless communication signal including the raw sensor data and evaluate performance of the milling machine.

2. The system of claim 1 , wherein the sensor comprises a milling sensor configured to sense one or more of a cutting depth and a cutting width of the cutting tool, wherein the milling sensor is further configured to determine a partial-cut width of material in front of the cutting tool from output of the milling sensor.

3. The system of claim 1 , wherein the sensor comprises a three-dimensional scanner or a plurality of depth sensors.

4. The system of claim 1 , wherein the sensor comprises a global navigation satellite system sensor configured to generate speed and location data for the milling machine.

5. The system of claim 1 , wherein the monitoring device is configured to:
determine removed paving material volume;
output an indicator of removed paving material volume; and
transmit the indicator to the communication device of the milling machine.

6. The system of claim 1 , wherein the milling machine further comprises an operator interface configured to receive processed sensor data and render a graphical display of the processed sensor data.

7. The system of claim 1 , wherein the monitoring device comprises a mobile computing device.

8. The system of claim 1 , wherein the monitoring device comprises a computer at a back-office location.

9. A method for determining and monitoring output of a milling machine, the method comprising:
sensing an operating parameter of the milling machine with a sensor;
transmitting data from the sensors of the milling machine to an off-board location via a first wireless communication signal;
receiving the first wireless communication signal at the off-board location at a remote location physically separate from the milling machine;
determining a performance parameter of the milling machine from the data at the off-board location at the remote location;
transmitting the performance parameter to the milling machine via a second wireless communication signal originated at the remote location; and
displaying the performance parameter on a display screen of the milling machine.

10. The method of claim 9 , wherein sensing the operating parameter of the milling machine comprises sensing a partial-cut width of the milling machine.

11. The method of claim 10 , wherein sensing the operating parameter of the milling machine further comprises sensing a cut depth and sensing a speed of the milling machine.

12. The method of claim 11 , wherein transmitting data from the sensor off-board the milling machine comprises time-stamping data relating to the operating parameter, the cut depth and the speed.

13. The method of claim 9 , wherein transmitting data from the sensor of the milling machine to an off-board location comprises transmitting raw sensor data.

14. The method of claim 9 , wherein transmitting the performance parameter to the milling machine comprises throttling a refresh rate of data provided to the milling machine to decrease resolution of the data by transmitting data generated by the sensor to the remote location at a second rate less than a first rate at which the sensor collects data.

15. The method of claim 9 , wherein transmitting data from the sensor of the milling machine to an off-board location comprises transmitting data from the sensor to a mobile computing device located at a jobsite of the milling machine.

16. The method of claim 9 , wherein transmitting data from the sensor of the milling machine to an off-board location comprises transmitting data from the sensor to a stationary computing device located in a back-office location.

17. The method of claim 9 , wherein transmitting data from the sensor of the milling machine to an off-board location comprises transmitting sensor data directly from a sensor to the off-board location via a sensor including a wireless communication device.

18. The method of claim 9 , further comprising performing jobsite analysis of the milling machine and another machine based on the performance parameter.

19. The system of claim 2 , further comprising an off-board computer at the remote location, wherein the off-board computer is configured to:
determine cut volume from the partial-cut width and the cutting depth at the remote location; and
communicate the cut volume from the remote location to the milling machine for display.

20. The method of claim 11 , wherein transmitting the performance para to the milling machine comprises:
determining cut volume from the partial-cut width and the cut depth at the remote location; and
communicating the cut volume from the remote location to the milling machine for display.
