A type information input unit receives an input of type information for identifying an attachment. A storage unit stores in advance correspondence between the type information and a weight or weight classification of the attachment. A specification unit specifies a corresponding weight or weight classification based on the type information input to the type information input unit.

Control device and control method

A control device for a working machine includes a position designation receiving unit configured to identify a designated position in a state image which is displayed on a display panel and a screen control unit configured to perform screen control based on an image displayed at the identified position out of part images constituting parts of the state image.

Working machine control device, working machine, and working machine control method for performing screen control based on identified position

A control line determinator determines whether or not a work state of a work implement is a predetermined work state. A display controller generates a display signal including a target surface of a construction object or a control line indicating a surface which is different from the target surface and which a bucket is to be prevented from entering. The display controller makes a display form of the control line or the target surface in the display signal different according to whether or not the work state is the predetermined work state.

Display control device and method for generating target line or control line of work machine

A display system for an excavation machine includes a calculator configured to calculate, based on vehicle state data indicating a position and a posture of a vehicle body of an excavation machine, working equipment outer shape data indicating an outer shape and a dimension of working equipment supported by the vehicle body, and working equipment state data indicating a posture of the working equipment, a reference vector extending in a widthwise direction of a bucket of the working equipment and passing through a specified portion of the bucket, and a display controller configured to cause a display device to display the bucket and a target line viewed from a direction orthogonal to the reference vector.

Display system for excavation machine, excavation machine, and display method for excavation machine

A display system of a working machine includes: a tilt sensor that detects a pitch angle and a roll angle of a working machine; a calculation unit that calculates a tilting position on polar coordinates that indicates a magnitude and a direction of tilt of the working machine based on the detected pitch angle and roll angle; a display unit that displays various kinds of information; a display processing unit that displays, on a predetermined region on a display screen of the display unit, a monitor-displayed level that performs a polar coordinate display of the tilting position and a marked line indicating a preset magnitude of tilt; and a setting processing unit that performs a setting to change display content of the monitor-displayed level.
