1 . A display device for a shovel, wherein:
the display device is configured to display a screen that includes
an image display area displaying an image represented by image data captured by an imaging device included in the shovel; and
a work information display area displaying an icon image corresponding to an instruction to correct a reference value used to calculate a weight of a load object conveyed by an end attachment of the shovel, and
a display mode of the icon image is changed to notify an operator of the shovel that an operation of correcting the reference value is permitted, when a state of the end attachment satisfies a predetermined condition.
2 . A display device for a shovel, wherein
the display device is configured to display a screen that includes
an image represented by image data captured by an imaging device included in the shovel; and
an icon image corresponding to an instruction to correct a reference value used to calculate a weight of a load object conveyed by an end attachment of the shovel,
a display mode of the icon image is changed to a display mode indicating that an operation of correcting the reference value is permitted, when a state of the end attachment satisfies a predetermined condition, and
the display mode of the icon image is displayed in a display mode indicating that the operation of correcting the reference value is invalid, when the state of the end attachment does not satisfy the predetermined condition.
3 . The display device according to claim 2 , wherein the predetermined condition is that the state of the end attachment is determined to be an empty load state.
4 . The display device according to claim 3 , wherein the predetermined condition is that a difference between a weight of the end attachment and the reference value is less than or equal to a predetermined threshold value.
5 . The display device according to claim 4 , wherein
an operation of setting the reference value is an operation of selecting an input device associated with the icon image, and
when the operation is performed, the weight of the end attachment when the predetermined condition is satisfied is set as the reference value.
6 . The display device according to claim 5 , wherein the screen is displayed in loading of the load object onto a cargo bed of a conveying vehicle from the end attachment.
7 . The display device according to claim 6 , wherein
the display device is configured to display another screen, said another screen including the image data captured by the imaging device and an icon image for displaying the screen, and
said another screen transitions to the screen when an input device corresponding to the icon image for displaying the screen is selected.
8 . The display device according to claim 7 , wherein
the screen is a loading work screen,
said another screen is a main screen,
the icon image for displaying the screen is an icon image for transitioning the main screen to the loading work screen, and
the input device corresponding to the icon image for displaying the screen is an input device corresponding to a tab displaying the icon image for transitioning the main screen to the loading work screen.
9 . The display device according to claim 1 , wherein the work information display area displays information on loading work.
10 . The display device according to claim 9 , wherein a load amount image, a remaining load amount, a loaded amount, an icon image of the end attachment, and a weight of earth and sand in the end attachment are displayed in the work information display area.
11 . The display device according to claim 10 , wherein
the load amount image includes an image of a side surface of a dump truck, and a bar chart image indicating a loaded amount on a cargo bed of the dump truck, and
the bar chart image indicates a ratio of the loaded amount of earth and sand on the cargo bed of the dump truck to a maximum load amount of the dump truck.
12 . A shovel comprising:
an upper swing body;
a lower traveling body;
an end attachment;
an imaging device;
a hardware processor configured to calculate a weight of a load object conveyed by the end attachment; and
a display device configured to display a screen that includes
an image display area displaying an image represented by image data captured by the imaging device, and
a work information display area displaying an icon image corresponding to an instruction to correct a reference value used to calculate the weight of the load object conveyed by the end attachment,
wherein the hardware processor is configured to change a display mode of the icon image upon determining a timing of correction of the reference value used to calculate the weight of the load object, and
the hardware processor is configured to
determine whether the end attachment is empty based on an output of a sensor of the shovel, and
change the display mode of the icon image to notify an operator of the shovel that the correction of the reference value is allowed, in response to determining that the end attachment is empty.
13 . The display device according to claim 1 , wherein the display device is configured to simultaneously display the image represented by the image data and the icon image on the same screen.
14 . The display device according to claim 1 , wherein the image represented by the image data captured by the imaging device includes at least one of a bird's eye view image, a front side image, a rear side image, a left side image, and a right side image of the shovel.
15 . The shovel according to claim 12 , wherein the display device is configured to simultaneously display the image represented by the image data and the icon image on the same screen.
16 . The shovel according to claim 12 , wherein the image represented by the image data captured by the imaging device includes at least one of a bird's eye view image, a front side image, a rear side image, a left side image, and a right side image of the shovel.
17 . The shovel according to claim 12 , wherein the hardware processor is configured to prohibit the correction of the reference value in response to determining that the end attachment is not empty.
18 . The shovel according to claim 12 , further comprising:
an attachment including a boom attached to the upper swing body, an arm attached to the boom, and the end attachment attached to the arm; and
a boom cylinder configured to drive the boom,
wherein the hardware processor is configured to
calculate a weight of the end attachment based on a thrust of the boom cylinder,
determine whether a difference between the weight of the end attachment and the reference value is less than or equal to a predetermined threshold value, and
determine that the end attachment is empty in response to determining that the difference between the weight of the end attachment and the reference value is less than or equal to the predetermined threshold value.
