Work machine
A work machine includes an attachment and a control device. The control device is configured to specify a hazardous zone in which a degree of hazard increases when an object falls during an operation of the attachment to lift and move the object, and make the specified hazardous zone visually recognizable.
1 . A work machine, comprising:
an attachment;
a memory; and
a hardware processor coupled to the memory and configured to
specify a hazardous zone in which a degree of hazard increases when an object falls during an operation of the attachment to lift and move the object, and
visualize the specified hazardous zone by causing a lighting device to illuminate the specified hazardous zone,
wherein the memory stores a learned model which has learned a relationship between a combination of the object and a work site and a zone having a high probability of coming into contact with the fallen object from a data set in which image data of the object, image data of the work site of the work machine, and image data indicating a state of the work site after the object falls are associated with one another, and
the hardware processor is further configured to
input image data including an image of the object and an image of the work site to the learned model; and
specify a zone output from the learned model as the hazardous zone.
2 . The work machine according to claim 1 , wherein the hazardous zone has the high probability of coming into contact with the fallen object when the object falls.
3 . The work machine according to claim 1 ,
wherein the work machine is an excavator, and
wherein the hardware processor is further configured to:
when an operation mode of the excavator is a normal operation mode, set a zone having a high probability of coming into contact with the attachment of the excavator during a rotating operation of the excavator as a first zone;
when the operation mode of the excavator is a crane mode, set a zone having a high probability of coming into contact with the fallen object during an operation of moving the object lifted by the attachment as a second zone; and
switch a range of the hazardous zone between the first zone and the second zone according to the operation mode of the excavator.
4 . The work machine according to claim 1 , wherein the hardware processor is further configured to visualize the specified hazardous zone around the work machine in the work site.
5 . The work machine according to claim 4 , wherein the hardware processor is further configured to visualize the specified hazardous zone on a surface of at least one of a ground or an object around the work machine in the work site.
6 . A work machine, comprising:
an attachment;
a memory; and
a hardware processor coupled to the memory and configured to
specify a hazardous zone in which a degree of hazard increases when an object falls during an operation of the attachment to lift and move the object, and
visualize the specified hazardous zone,
wherein the memory stores a learned model which has learned a relationship between a combination of the object and a work site and a zone having a high probability of coming into contact with the fallen object from a data set in which image data of the object, image data of the work site of the work machine, and image data indicating a state of the work site after the object falls are associated with one another, and
the hardware processor is further configured to
input image data including an image of the object and an image of the work site to the learned model; and
specify a zone output from the learned model as the hazardous zone.
7 . The work machine according to claim 6 , wherein the hazardous zone has the high probability of coming into contact with the fallen object when the object falls.
8 . The work machine according to claim 6 ,
wherein the work machine is an excavator, and
wherein the hardware processor is further configured to:
when an operation mode of the excavator is a normal operation mode, set a zone having a high probability of coming into contact with the attachment of the excavator during a rotating operation of the excavator as a first zone;
when the operation mode of the excavator is a crane mode, set a zone having a high probability of coming into contact with the fallen object during an operation of moving the object lifted by the attachment as a second zone; and
switch a range of the hazardous zone between the first zone and the second zone according to the operation mode of the excavator.
9 . The work machine according to claim 6 , wherein the hardware processor is further configured to visualize the specified hazardous zone around the work machine in the work site.
10 . The work machine according to claim 9 , wherein the hardware processor is further configured to visualize the specified hazardous zone on a surface of at least one of a ground or an object around the work machine in the work site.
