Abstract

A management system for a mining machine on which tires are mounted and which travels in a mine by operation performed by a driver includes: a determination unit configured to determine whether or not a damaging operation damaging the tires has been carried out; a data acquisition unit configured to acquire damaging operation data indicating carrying out of the damaging operation, and one or both of driver identification data indicating a driver who has carried out the damaging operation and position data indicating a position of the mining machine on which the damaging operation has been carried out; and a data output unit configured to output association data containing the damaging operation data associated with one or both of the driver identification data and the position data.

First claim

The invention claimed is:

1. A management system for a mining machine on which tires are mounted and which travels in a mine by operation performed by a driver, the management system comprising:
a determination unit configured to determine whether or not a damaging operation damaging the tires has been carried out;
a data acquisition unit configured to acquire damaging operation data indicating carrying out of the damaging operation, and driver identification data indicating the driver who has carried out the damaging operation;
a data output unit configured to output association data containing the damaging operation data associated with the driver identification data; and
a detector configured to detect a traveling characteristic of the mining machine, wherein
the detector detects a traveling characteristic of the mining machine,
the determination unit determines an occurrence of the damaging operation based on a detection signal from the detector, and
the data output unit outputs the association data in a report showing at least one of a frequency, a damage amount, and a position of the damaging operation for the driver.

2. The management system for a mining machine according to claim 1 , wherein
the data acquisition unit is configured to acquire position data indicating a position of the mining machine on which the damaging operation has been carried out; and
the data output unit is configured to output association data containing the damaging operation data associated with both of the driver identification data and the position data.

3. The management system for a mining machine according to claim 2 , further comprising a position detection device configured to detect a position of the mining machine, wherein
the data acquisition unit acquires the position data from the position detection device.

4. The management system for a mining machine according to any one of claims 1 , 3 and 2 , wherein, the damaging operation includes at least one of a rapid deceleration operation of decelerating the mining machine at a first speed or higher per unit time, a stationary steering operation of changing a direction of the tires of the mining machine at a second speed or lower, and an aggressive cornering operation of making the mining machine travel along a curve having a radius of curvature of a predetermined value or smaller at a third speed or higher.

5. The management system for a mining machine according to claim 4 , wherein the detector is a speed detection device configured to detect a traveling speed and a deceleration of the mining machine, wherein
the determination unit determines whether or not the damaging operation has been carried out on the basis of a detection signal from the speed detection device.

6. The management system for a mining machine according to claim 1 , wherein
the data acquisition unit acquires mining machine identification data indicating the mining machine on which the damaging operation has been carried out, and
the association data contains the damaging operation data associated with the mining machine identification data.

7. The management system for a mining machine according to claim 1 , wherein
the data acquisition unit acquires time point data indicating a time point at which the damaging operation has been carried out, and
the association data contains the damaging operation data associated with the time point data.

8. The management system for a mining machine according to claim 1 , further comprising a travel path computation unit configured to generate a reference travel path in the mine on the basis of position data of an actual travel path along which multiple mining machines have traveled in the mine, wherein
the data acquisition unit acquires the damaging operation data when the mining machine is present on the reference travel path.

9. The management system for a mining machine according to claim 1 , wherein the data output unit includes a report creation unit configured to create a report of the association data.

10. A management system for a mining machine on which tires are mounted and which travels in a mine by operation performed by a driver, the management system comprising:
a determination unit configured to determine whether or not a damaging operation damaging the tires has been carried out;
a data acquisition unit configured to acquire damaging operation data indicating carrying out of the damaging operation, and driver identification data indicating the driver who has carried out the damaging operation;
a data output unit configured to output association data containing the damaging operation data associated with the driver identification data;
a speed detection device configured to detect a traveling speed and a deceleration of the mining machine; and
a load detection device configured to detect a load acting on the tire, wherein
the damaging operation includes a rapid deceleration operation of decelerating the mining machine at a first speed or higher per unit time, and
the determination unit determines whether or not the damaging operation has been carried out on the basis of a detection signal from the speed detection device, and determines whether or not the rapid deceleration operation has been carried out on the basis of deceleration data indicating the deceleration of the mining machine and load data indicating the load acting on the tires, and
the data output unit outputs the association data in a report showing at least one of a frequency, a damage amount, and a position of the damaging operation for the driver.

11. The management system for a mining machine according to claim 10 , wherein
the mining machine includes a dump truck having a vehicle body and a vessel supported by the vehicle body, and
the load acting on the tires varies according to a load placed on the vessel.

12. A management system for a mining machine on which tires are mounted and which travels in a mine by operation performed by a driver, the management system comprising:
a determination unit configured to determine whether or not a damaging operation damaging the tires has been carried out;
a data acquisition unit configured to acquire damaging operation data indicating carrying out of the damaging operation, and driver identification data indicating the driver who has carried out the damaging operation;
a data output unit configured to output association data containing the damaging operation data associated with the driver identification data;
a speed detection device configured to detect a traveling speed and a deceleration of the mining machine; and
a steering force detection device configured to detect a steering force that changes a direction of the tires, wherein
the damaging operation includes a stationary steering operation of changing the direction of the tires at a second speed or lower, and
the determination unit determines whether or not the damaging operation has been carried out on the basis of a detection signal from the speed detection device, and determines whether or not the stationary steering operation has been carried out on the basis of traveling speed data indicating the traveling speed of the mining machine and steering force data indicating the steering force.

13. The management system for a mining machine according to claim 12 , wherein
the mining machine includes a dump truck having a vehicle body and a vessel supported by the vehicle body, and
the load acting on the tires varies according to a load placed on the vessel.

14. A management system for a mining machine on which tires are mounted and which travels in a mine by operat
