Abstract

A shovel includes a lower traveling body, an upper turning body, an attachment including a boom, an arm, and an end attachment, a boom state detector configured to detect the state of the boom, an arm state detector configured to detect the state of the arm, an end attachment state detector configured to detect the state of the end attachment, and a hardware processor. The hardware processor is configured to obtain information on the position of the end attachment based on the respective outputs of the detectors, correlate the information on the position of the end attachment with information on the position of an underground object obtained based on the output of an underground object detector, and calculate the distance between the end attachment and the underground object. The hardware processor is further configured to control the shovel such that the distance is prevented from falling below a predetermined value.

Claims (35)

1. A shovel comprising:

a lower traveling body;

an upper turning body turnably attached to the lower traveling body;

an attachment including a boom, an arm, and an end attachment, the attachment being attached to the upper turning body;

a boom state detector configured to detect a state of the boom;

an arm state detector configured to detect a state of the arm;

an end attachment state detector configured to detect a state of the end attachment; and

a hardware processor configured to

obtain information on a position of the end attachment based on respective outputs of the boom state detector, the arm state detector, and the end attachment state detector,

correlate the information on the position of the end attachment with information on a position of an underground object obtained based on an output of an underground object detector and calculate a distance between the end attachment and the underground object, and

control the shovel such that the distance is prevented from falling below a predetermined value.

2. The shovel as claimed in claim 1 , wherein the underground object detector is mounted on the shovel and is configured to output the information on the position of the underground object to the control device.

3. The shovel as claimed in claim 1 , wherein the hardware processor is configured to display an image of the underground object.

4. The shovel as claimed in claim 1 , further comprising:

a storage device,

wherein the underground object includes a buried object,

information on a position of the buried object is stored in the storage device, and

the hardware processor is configured to correct the information on the position of the buried object based on the output of the underground object detector.

5. The shovel as claimed in claim 4 , wherein the hardware processor is configured to display an image of the buried object such that a difference between the information on the position of the buried object stored in the storage device and information on a position of the buried object detected by the underground object detector is recognizable.

6. The shovel as claimed in claim 1 , further comprising:

a display device configured to display a screen graphically representing a relative relationship between the end attachment and the underground object,

wherein a graphic shape configured to move in accordance with a movement of the end attachment is displayed within the screen.

7. The shovel as claimed in claim 1 , further comprising:

an audio output device configured to output an audio such that the output audio changes in accordance with a relative relationship between the end attachment and the underground object.

8. The shovel as claimed in claim 1 , wherein the hardware processor is configured to correct information on a position of a buried object based on information on a position of a burial indicator sheet.

9. A system of managing a shovel, the shovel including a lower traveling body; an upper turning body turnably attached to the lower traveling body; an attachment including a boom, an arm, and an end attachment, the attachment being attached to the upper turning body; a boom state detector configured to detect a state of the boom; an arm state detector configured to detect a state of the arm; an end attachment state detector configured to detect a state of the end attachment; and a shovel hardware processor, the system comprising:

a management apparatus including an apparatus hardware processor, the apparatus hardware processor being configured to

obtain information on a position of the end attachment based on respective outputs of the boom state detector, the arm state detector, and the end attachment state detector, and

correlate the information on the position of the end attachment with information on a position of an underground object obtained based on an output of an underground object detector and calculate a distance between the end attachment and the underground object, and

wherein the shovel hardware processor is configured to control the shovel such that the distance is prevented from falling below a predetermined value.

10. The system as claimed in claim 9 , wherein

the management apparatus includes a storage part,

the underground object includes a buried object,

information on a position of the buried object is stored in the storage device, and

the apparatus hardware processor is configured to correct the information on the position of the buried object based on the output of the underground object detector.
