Abstract

A construction management device generates construction information for an excavation machinery having a work machine, a swing body to which the work machine is attached, and a traveling body traveling with the swing body mounted thereon. The construction management device includes a work machine position information generation part determining work machine position information as information on a position of the work machine; a traveling body position information generation part determining traveling body position information as information on a position of the traveling body; and a construction position information generation part using either the work machine position information or the traveling body position information to generate construction position information as information on a position of construction by the excavation machinery, and while the excavation machinery travels, using not the work machine position information, but the traveling body position information to generate the construction position information.

First claim

The invention claimed is:

1. A construction management device for excavation machinery configured to generate information on a result of construction by the excavation machinery having a work machine, a swing body to which the work machine is attached, and a traveling body traveling with the swing body mounted thereon, the device comprising:
a vehicle state detection part that detects information on current position and posture of the excavation machinery;
a work machine position information generation part that determines work machine position information as information on a position of the work machine, based on a result of a detection by the vehicle state detection part;
a traveling body position information generation part that determines traveling body position information as information on a position of the traveling body, based on the result of the detection by the vehicle state detection part; and
a construction position information generation part that uses one of the work machine position information and the traveling body position information to generate construction position information as information on a position of construction by the excavation machinery, wherein when the excavation machinery travels, the construction position information generation part uses not the work machine position information, but the traveling body position information to generate the construction position information,
wherein when the traveling body is stopped, the construction position information generation part uses the work machine position information to generate the construction position information.

2. The construction management device for excavation machinery according to claim 1 , wherein the construction position information generation part displays the construction position information on a display device included in the excavation machinery.

3. The construction management device for excavation machinery according to claim 1 , further comprising:
an operation part that controls an operation of the traveling body and an operation detection part that detects an operation of the operation part, wherein
when the operation detection part detects an operation for traveling the traveling body, the construction position information generation part uses the traveling body position information to generate the construction position information, and when the operation detection part detects an operation for stopping the traveling body, the construction position information generation part uses the work machine position information to generate the construction position information.

4. The construction management device for excavation machinery according to claim 3 , wherein the operation part includes a pilot-pressure operation lever or pedal.

5. The construction management device for excavation machinery according to claim 1 , wherein
when using the work machine position information to generate the construction position information, when current work machine position information generated by the work machine position information generation part becomes smaller than the position of the construction position information in a height direction, the construction position information generation part updates the construction position information to the current work machine position information.

6. The construction management device for excavation machinery according to claim 1 , wherein
when using the travel body position information to generate the construction position information, the construction position information generation part updates the construction position information to current traveling position information generated by the traveling body position information generation part.

7. The construction management device for excavation machinery according to claim 1 , wherein the work machine position information refers to information on a position of a blade edge of a bucket attached to the work machine.

8. The construction management device for excavation machinery according to claim 1 , wherein the traveling body position information generation part generates the traveling body position information, based on a movement direction in which the excavation machinery travels.

9. Excavation machinery, comprising:
a work machine;
a swing body to which the work machine is attached;
a traveling body that travels with the swing body mounted thereon; and
the construction management device for excavation machinery according to claim 1 .

10. A construction management system, comprising:
a construction plan creation part that creates a construction plan for the excavation machinery according to claim 9 ;
a construction plan transmission part that transmits the construction plan to the construction management device in the excavation machinery; and
a construction position information acquisition part that acquires the construction position information generated by the construction management device in the excavation machinery.

11. A construction management device for excavator, configured to generate information on a result of construction by the excavator having a work machine, a swing body to which the work machine is attached, and a traveling body traveling with the swing body mounted thereon, the device comprising:
a vehicle state detection part that detects information on current position and posture of the excavator;
a work machine position information generation part that determines work machine position information as information on a position of the work machine, based on a result of a detection by the vehicle state detection part;
a traveling body position information generation part that determines traveling body position information as information on a position of the traveling body, based on the result of the detection by the vehicle state detection part;
a pilot-pressure traveling lever that controls an operation of the traveling body; and
an operation detection part that detects an input to the traveling lever, wherein
when the operation detection part detects an input for traveling the traveling body, a construction position generation information part uses the traveling body position information to generate a construction position information, and when the operation detection part detects an input for stopping the traveling body, the construction position generation information part uses the work machine position information to generate the construction position information.
