A system and method for various levels of automation of a swing-to-hopper motion for a rope shovel. An operator controls a rope shovel during a dig operation to load a dipper with materials. A controller receives position data, either via operator input or sensor data, for the dipper and a hopper where the materials are to be dumped. The controller then calculates an ideal path for the dipper to travel to be positioned above the hopper to dump the contents of the dipper. In some embodiments, the controller outputs operator feedback to assist the operator in traveling along the ideal path to the hopper. In some embodiments, the controller restricts the dipper motion such that the operator is not able to deviate beyond certain limits of the ideal path. In some embodiments, the controller automatically controls the movement of the dipper to reach the hopper.

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.

Display system of excavating machine and excavating machine

An excavation control system includes a working unit having a bucket, a designed landform data storage part storing designed landform data, a bucket position data generation part that generates bucket position data, a designed surface data generation part, and an excavation limit control part. The designed surface data generation part generates superior and subordinate designed surface data based on the designed landform and bucket position data. The superior designed surface data indicates a superior designed surface corresponding to a position of the bucket. The subordinate designed surface data indicates a first subordinate designed surface linked to the superior designed surface. The designed surface data generation part generates shape data indicating shapes of the superior designed surface and the first subordinate designed surface. The excavation limit control part automatically adjusts a position of the bucket.

PROBLEM TO BE SOLVED: To provide a display system of a hydraulic shovel and a control method for the same capable of easily grasping a positional relation between a target surface and the hydraulic shovel.SOLUTION: In a display system of a hydraulic shovel, a calculation section sets a prescribed display range 55 for topography data to be displayed as a guidance screen. The guidance screen shows a section from a lateral view of a target surface included in the display range 55 as well as a current position of the hydraulic shovel. Then, the calculation section calculates a position of a start point Ps closest to a vehicle main body as well as a position of an end point Pe at a distant of a maximum reach length of a work machine from the start point Ps in the section from the lateral view of the target surface based on the topographic data, work machine data and a current position of the vehicle main body. The calculation section also calculates a position of a prescribed reference point Pb of the display range 55 based on the positions of the start point Ps and the end point Pe.

Display system of hydraulic shovel and control method for the same

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.

Display system of hydraulic shovel, and control method therefor

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.

Hydraulic shovel positional guidance system and method of controlling same

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.
