Abstract: A system includes a mode selecting unit, a screen generating unit, and a target-position setting unit. The mode selecting unit selects, as a control mode for an automatic revolution control, either a rightward loading-revolution mode or a leftward loading-revolution mode. The screen generating unit generates a rightward-revolution teaching screen used to teach the target position in the rightward loading-revolution mode, and a leftward-revolution teaching screen used to teach the target position in the leftward loading-revolution mode. The target-position setting unit sets an end point of returning revolution and an end point of loading revolution taught through the rightward-revolution teaching screen when the rightward loading-revolution mode is selected, and sets the end point of returning revolution and the end point of loading revolution taught through the leftward-revolution teaching screen when the leftward loading-revolution mode is selected.

Abstract: A display system includes an orientation acquisition unit and a screen generating unit. The orientation acquisition unit acquires a current orientation of a work implement of a work machine, an orientation of an end point of returning revolution relative to the work machine, and an orientation of an end point of loading revolution relative to the work machine. The screen generating unit generates a guide screen based on the current orientation of the work implement of the work machine, the orientation of the end point of returning revolution, and the orientation of the end point of loading revolution. The guide screen includes a work-orientation display indicating the current orientation of the work implement, an orientation circular display, and first and second orientation displays disposed along the orientation circular display to indicate the orientations of the end point of returning revolution and the end point of loading revolution.
