In a display system in an excavator, a position of an upper boundary line and a position of a lower boundary line are calculated. The upper boundary line indicates a height of a top of a cross section of a display object surface. The lower boundary line indicates a height of a bottom of the cross section of the display object surface. A predetermined reference point of a display range is set based on a positional relationship in an up-and-down direction between the current position of the excavator and the upper boundary line or between the current position of the excavator and the lower boundary line. A guidance picture showing a cross section of the display object surface included in the predetermined display range as seen from a side of the excavator, and the current position of the excavator, is displayed.

Display system in an excavator and method for controlling same

A construction management device generates construction information for an excavation machinery having a work machine, a swing body to which the work machine is attached, and a traveling body traveling with the swing body mounted thereon. The construction management device includes a work machine position information generation part determining work machine position information as information on a position of the work machine; a traveling body position information generation part determining traveling body position information as information on a position of the traveling body; and a construction position information generation part using either the work machine position information or the traveling body position information to generate construction position information as information on a position of construction by the excavation machinery, and while the excavation machinery travels, using not the work machine position information, but the traveling body position information to generate the construction position information.

The display system includes: stroke sensors that detect position information of working equipment relative to a body; a real image display unit; a combiner; and a display controller. Based on the position information of the working equipment, the display controller controls a displayed position of work-support information along a surface of the combiner and a depthwise displayed position of the work-support information defined in a forward direction relative to a cab. A projection image of the work-support information visible to an operator is thus displayed around the working equipment.

In a display system in an excavator, a position of an upper boundary line and a position of a lower boundary line are calculated. The upper boundary line indicates a height of a top of a cross section of a display object surface. The lower boundary line indicates a height of a bottom of the cross section of the display object surface. When the current position of the excavator is between the upper boundary line and the lower boundary line, a predetermined reference point of a display range is set to a predetermined position between the upper and lower boundary lines. When the current position of the excavator is above the upper boundary line, the reference point is set above the predetermined position. When the current position of the excavator is below the lower boundary line, the reference point is set below the predetermined position.

An display system of an excavating machine includes: a vehicle condition detector detecting information related to a current position and a posture of the excavating machine having a work equipment including a bucket; a memory unit storing position information of a target surface indicating a target shape of an object to be worked; a display unit displaying the bucket and position information of a design surface and the target surface; and a processing unit calculating a position of a blade edge of the bucket based on the information related to the current position and the posture of the excavating machine, and, when at least part of the bucket enters a predetermined range in a periphery of the target surface in a direction orthogonal to the target surface, displaying a trajectory of the blade edge which is calculated based on the position of the blade edge and which exists in the predetermined range.

A calculation unit of a hydraulic shovel display system sets a predetermined display range displayed as a guidance picture for land shape data. The guidance picture shows a cross section of a target surface included in a display range as seen from a side of a main vehicle body, and a current position of the hydraulic shovel. The calculation unit calculates a position of a start point nearest the main vehicle body and a position of an end point set apart from the start point by a maximum reach length of the work machine in the cross section of the target surface as seen from the side based on land shape data, work machine data and a current position of the main vehicle body. The calculation unit calculates a predetermined reference point of the display range based on the positions of the start point and the end point.

Display system in hydraulic shovel and control method therefor

In a hydraulic shovel operability range display device, a calculation unit is configured to set a boundary between an operability range and an underbody area along a vertical direction in a global coordinate system when a vehicle body is horizontally oriented. When the vehicle body is tilted forward, the calculation unit is configured to set the boundary so as to be maintained along the vertical direction in the global coordinate system. When the vehicle body is tilted backwards, the calculation unit is configured to correct the boundary between the operability range and the underbody area so that an angle formed by the boundary and the ground surface on which the vehicle body is positioned is at least 90&#xb0;.

Hydraulic shovel operability range display device and method for controlling same

In a hydraulic shovel positional guidance system, an optimal work position calculation unit is configured to calculate an optimal work position of a main vehicle body where a diggable range in which a target surface and an operability range overlap is largest. A display unit is configured to display a guidance picture showing the optimal work position.
