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.

A display system for an excavating machine allowing an upper swing body including a work implement to swing about a predetermined swing central axis. The display system includes a processing unit that obtains target swing information indicating an amount of swing of the upper swing body, based on information including a direction of a tooth edge of the bucket, information including a direction orthogonal to a target plane indicating a target shape of a work object, and information including a direction of the swing central axis, and displays an image corresponding to the obtained target swing information, the amount of swing being required for the tooth edge of the bucket to face the target plane, and the direction of the tooth edge of the bucket being determined based on information about a current position and posture of the excavating machine.

A display system of excavating machine includes a vehicle state detection unit configured to detect information related to a current position and a posture of the excavator as an excavating machine; a storage unit configured to store at least position information of a target surface indicating a target shape of an object to be worked; a bucket tilt detection unit configured to detect a tilt angle of the bucket; and a processing unit configured to obtain an angle between the edge and the target surface from a position of the edge of the bucket obtained based on the tilt angle of the bucket and the information related to a current position and a posture of the excavator and to display posture information indicating information related to a posture of the bucket on a screen of a display unit based on the obtained edge tilt angle.

Display system of excavating machine, excavating machine, and display computer program of excavating machine

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.

A display system of an excavating machine including a work machine with a bucket and a main body part to which the work machine is attached, includes: a storage storing positional information of a design surface indicating a design land shape and outer shape information of the bucket; and a processor determining, among measurement reference points predetermined along an outer shape of a buttock part of the bucket for measuring a position, including at least a tip of the bucket, a measurement reference point closest to the design surface, based on information on a current position of the excavating machine, information on a posture of the main body part, information on a position of the tip of the bucket, and the outer shape information of the bucket.

Display system of excavating machine and excavating machine

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.

A display system of an excavating machine including a work machine having a bucket with an excavation edge and an arm to which the bucket is swingably attached, and a body to which the work machine is attached, the system including: a vehicle condition detector detecting first information related to a current position of the excavating machine and second information related to a posture of the body; a storage storing position information of a target surface indicating a target shape of an object and appearance information of the bucket; and a processor obtaining virtual images indicating positions of planes passing through both ends of the excavation edge from among planes parallel to a plane on which the arm moves based on the first and second information, and the appearance information, and displaying the virtual images on a screen with the bucket as viewed from above the excavating machine.

A display system in a hydraulic shovel has a calculation unit and a display unit. The calculation unit is configured to calculate a distance between a design surface and a position closest to the design surface among positions of a blade edge of a bucket in a widthwise direction of the blade edge based on positional information for the blade edge and the design surface. The display unit is configured and arranged to display a guidance picture. The guidance picture includes an image showing the positional relationship between the design surface and the blade edge of the bucket, and information indicating the distance between the design surface and the position closest to the design surface.

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

A laser control apparatus that controls a laser device acquires state data from the laser device indicating the state of the laser device every time a specific preset event occurs, such as the generation of a fixed number of discharge pulses, for example, and transmits this data to a monitor terminal. The monitor terminal transfers the received state data to a server device via a communication channel. In the server device, a database is updated and output data is generated based on the transferred state data. This output data is input to a display terminal via a communication channel, and is displayed on the display terminal.
