Abstract

An evaluation apparatus includes a detected data acquisition unit that acquires photograph data of a bucket of a work equipment, a first display control unit that displays the photograph data on a display screen of a display device, a second display control unit that displays on the display screen a graphic representing at least part of an outline of the bucket as viewed from a side, and moves the graphic on the display screen by an operation of an input device, and an identification unit that distinguishes the bucket from excavated material above an opening end of the bucket on the display screen based on the graphic aligned with the bucket.

First claim

The invention claimed is:

1. A working equipment operator evaluation apparatus for evaluating the operation of the work equipment, the evaluation apparatus comprising:
a detected data acquisition unit configured to acquire photograph data of a bucket of a work equipment;
a first display control unit configured to display the photograph data on a display screen of a display device;
a second display control unit configured to display on the display screen a graphic representing at least part of an outline of the bucket as viewed from a side and enabling movement of the graphic on the display screen by an operation of an input device;
an identification unit configured to distinguish the bucket from excavated material above an opening end of the bucket on the display screen based on the graphic aligned with the bucket; and
an excavation amount calculation unit configured to calculate an excavation efficiency in an excavation operation of the bucket by determining an area of the excavated material existing above the opening end of the bucket.

2. The evaluation apparatus according to claim 1 , wherein the graphic includes a line representing the opening end of the bucket.

3. The evaluation apparatus according to claim 1 , wherein the input device includes an input device provided to the display screen.

4. The evaluation apparatus according to claim 1 , wherein
the work equipment is operated by an operator through an operating device to perform the excavation operation, and
the evaluation apparatus comprises an evaluation data generation unit configured to generate evaluation data of the operator related to the excavation operation based on a first detected data indicating an excavation amount calculated by the excavation amount calculation unit and a second detected data indicating excavation time.

5. The evaluation apparatus according to claim 4 , further comprising a target data acquisition unit configured to acquire target data indicating a target excavation amount of the bucket, wherein the evaluation data generation unit generates the evaluation data based on a difference between the first detected data and the target data.

6. An evaluation method for evaluating the operation of a work equipment comprising:
acquiring photograph data of a bucket of a work equipment;
displaying the photograph data on a display screen of a display device;
displaying on the display screen a graphic representing at least part of an outline of the bucket as viewed from a side;
moving the graphic on the display screen based on input data generated by an operation of an input device to a position on the displayed photograph data corresponding to the bucket of the work equipment; and
distinguishing the bucket from excavated material above an opening end of the bucket on the display screen based on the graphic being aligned with the bucket.

7. The evaluation apparatus according to claim 2 , wherein
the work equipment is operated by an operator through an operating device to perform the excavation operation, and
the evaluation apparatus comprises an evaluation data generation unit configured to generate evaluation data of the operator related to the excavation operation based on a first detected data indicating an excavation amount calculated by the excavation amount calculation unit and a second detected data indicating excavation time.

8. The evaluation apparatus according to claim 3 , wherein
the work equipment is operated by an operator through an operating device to perform the excavation operation, and
the evaluation apparatus comprises an evaluation data generation unit configured to generate evaluation data of the operator related to the excavation operation based on first detected data indicating an excavation amount calculated by the excavation amount calculation unit and second detected data indicating excavation time.

9. The evaluation apparatus according to claim 7 , comprising a target data acquisition unit configured to acquire target data indicating a target excavation amount of the bucket, wherein the evaluation data generation unit generates the evaluation data based on a difference between the first detected data and the target data.

10. The evaluation apparatus according to claim 8 , comprising a target data acquisition unit configured to acquire target data indicating a target excavation amount of the bucket, wherein the evaluation data generation unit generates the evaluation data based on a difference between the first detected data and the target data.

11. A computer program for evaluating an operator of a working equipment, the computer program being stored in a portable device, comprising:
acquiring photograph data of a bucket of a work equipment;
displaying the photograph data on a display screen of a display device;
displaying on the display screen a graphic representing at least part of an outline of the bucket as viewed from a side;
moving the graphic to a position of the displayed photograph data corresponding to the bucket of the working equipment on the display screen based on input data generated by an operation of an input device; and
distinguishing the bucket from excavated material above an opening end of the bucket on the display screen based on the graphic aligned with the bucket.
