Abstract

A computer-implemented method for providing a warning including the steps: obtaining data relating to the location of a hazardous object and obtaining data relating to the location of a material handling machine. The computer to compare the location of the material handling machine to the location of the hazardous object and estimates a probability of a hazardous event occurring. If the estimate exceeds a threshold valve, a warning is issued by the computer.

Claims

1. A computer-implemented method for providing a warning including the steps:

obtaining data relating to the location of an object;

obtaining data relating to the location of a material handling machine;

estimating a probability of damage occurring by using the computer to compare the location of the material handling machine to the location of the object;

providing, via the material handling machine, a warning, based on the estimate, to an operator of the material handling machine, the warning comprising an alarm; and

determining the type of the material handling machine, and wherein estimating the probability of the damage occurring is based on the type of the material handling machine.

2. A method according to claim 1, wherein the location of the object is below ground level, or wherein the location of the object is above ground level.

3. A method according to claim 2, further including obtaining data relating to the distance of the object below or above the ground level, wherein estimating the probability of damage occurring is based on the data relating to the distance of the object below or above the ground level.

4. A method according to claim 1, further including communicating, using a communication system, the data relating to the location of the object to the computer.

5. A method according to claim 4, further including communicating, using the communication system, the data relating to the location of the material handling machine to the computer.

6. A method according to claim 4, further including communicating, using the communication system, the warning to and/or from the material handling machine.

7. A method according to claim 1, wherein the material handling machine is an excavator, or a backhoe loader, or a tele-handler.

8. A method according to claim 1, wherein the material handling machine has a material handling implement, the method further including determining the position of the material handling implement relative to the rest of the material handling machine, wherein estimating the probability of the damage occurring is based on the determined position of the material handling implement relative to the rest of the material handling machine.

9. A method according to claim 8, wherein the material handling machine has a hydraulic system that manoeuvers the material handling implement and the method includes determining the pressure in the hydraulic system, wherein estimating the probability of the damage occurring is based on the pressure in the hydraulic system.

10. A method according to claim 8, wherein the material handling machine comprises a ground-engaging material handling implement.

11. A method according to claim 8, wherein determining the position of the material handling implement relative to the rest of the material handling machine comprises determining the height of the material handling implement relative to the rest of the material handling machine.

12. A method according to claim 1, further including determining whether the material handling machine is moving, wherein estimating the probability of the damage occurring is based on whether the material handling machine is moving.

13. A method according to claim 1, wherein the material handling machine has an engine and the method further includes determining whether the engine is running, wherein estimating the probability of the damage occurring is based on the whether the engine is running.

14. A method according to claim 1, wherein the alarm comprises an audible, visual or vibration alarm, or wherein providing the warning includes sending a message containing data about the estimate of the probability of damage occurring to and/or from the material handling machine.

15. A method according to claim 1, further including determining the speed and/or direction at which the material handling machine is moving, wherein the probability of the damage occurring is estimated based on the determined speed and/or direction.

16. A method according to claim 1, wherein the material handling machine has an engine and the method further includes determining the speed at which the engine is running, wherein the probability of the damage occurring is estimated based on the determined speed.

17. A material handling machine including:

a processor that is configured to;

receive data relating to the location of an object and data relating to the location of the material handling machine;

compare the location of the material handling machine and the location of the object;

estimate a probability of damage occurring based on the comparison; and

provide a warning based on the estimate to a user of the material handling machine, the warning comprising an alarm.

18. A system for providing a warning including:

a processor that is configured to;

receive data relating to the location of an object and data relating to the location of a material handling machine;

compare the location of the material handling machine and the location of the object;

estimate a probability of damage occurring based on the comparison; and

provide, via the material handling machine, a warning based on the estimate to a user of the material handling machine, the warning comprising an alarm.

19. A non-transitory computer-readable storage medium storing instructions which when executed by a processor causes the processor to execute the steps of:

comparing data relating to the location of an object and data relating to the location of a material handling machine;

estimating the probability of damage occurring based on the comparing; and

providing, to a user of the material handling machine, a warning based on the estimate, the warning comprising an alarm.

20. A method according to claim 19, wherein providing the warning comprises presenting, to the user of the material handling machine, the warning via a user interface.
