Abstract
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.
Claims11
A positional guidance system for guiding a hydraulic shovel to a target surface within a work area, the hydraulic shovel including a main vehicle body and a work machine attached to the main vehicle body, the positional guidance system comprising:
- a land shape data storage unit configured and arranged to store land shape data indicating a position of the target surface;
- a work machine data storage unit configured and arranged to store work machine data indicating an operability range around the main vehicle body to which the work machine is capable of reaching;
- a position detector unit configured and arranged to detect a current position of the main vehicle body;
- an optimal work position calculation unit configured to calculate an optimal work position of the main vehicle body where a diggable range, in which the target surface and the operability range overlap, is largest, based on the land shape data, the work machine data, and the current position of the main vehicle body;
- and
- a display unit configured and arranged to display a guidance picture showing the optimal work position.
A method for controlling a positional guidance system for guiding a hydraulic shovel to a target surface within a work area, the hydraulic shovel including a main vehicle body and a work machine attached to the main vehicle body, the method comprising of:
- detecting a current position of the main vehicle body;
- calculating an optimal work position of the main vehicle body where a diggable range, in which a target surface and an operability range around the main vehicle body to which the work machine is capable of reaching overlap, is largest, based on land shape data indicating a position of the target surface, work machine data indicating the operability range, and the current position of the main vehicle body;
- and
- displaying a guidance picture showing the optimal work position.
