Rock Drilling Rig Display for Fan Pattern Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Positioning a drilling unit in a rock cavern is laborious due to the difficulty in displaying all degrees of freedom in a two-dimensional display device, especially when drilling reinforcement holes in a fan-like pattern, as the existing systems struggle to effectively present the location and direction of the drilling unit relative to the fan plane and drill holes.
Innovation Solution
The method involves presenting a display image with at least two simultaneously active partial views using differing projections, allowing the operator to see the location of the drilling unit relative to the fan plane and drill holes in both xz and xy directions, facilitating intuitive connection between displayed directions and physical motion, thereby simplifying the positioning process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single two-dimensional view is used to display positioning information, then the display device is simple, but it is difficult to display all degrees of freedom of three-dimensional positioning
Solution Approach 1:
The display is segmented into multiple partial views, each showing a different projection (e.g., top view, side view, front view) of the three-dimensional positioning information. This allows comprehensive display of all degrees of freedom while maintaining a simple two-dimensional display device structure.
Solution Approach 2:
Multiple two-dimensional partial views are arranged in a specific layout on the display device, effectively creating a multi-dimensional information presentation from two-dimensional projections. This resolves the contradiction by using dimensional arrangement to convey three-dimensional positioning data.
2Loss of information
If multiple views are displayed to show all positioning degrees of freedom, then positioning information is complete, but the display becomes complex and difficult to interpret
Solution Approach 1:
The complex three-dimensional positioning information is segmented into multiple simple two-dimensional partial views, each showing a specific projection. This segmentation makes the information easier to interpret while maintaining completeness.
Solution Approach 2:
The partial views are arranged in a specific spatial layout on the display that corresponds to the physical arrangement of the drilling unit and fan plane, creating an intuitive spatial relationship that ease of operation.
3Device complexity
If the drilling unit is positioned manually using a single view, then the control system is simple, but the positioning process is laborious and time-consuming
Solution Approach 1:
The control system presents segmented partial views that correspond to different control dimensions, allowing the operator to position the drilling unit more efficiently by viewing relevant projections without increasing overall system complexity.
Solution Approach 2:
Multiple partial views are displayed simultaneously in a multi-dimensional arrangement, enabling the operator to assess positioning accuracy across all degrees of freedom at once, thereby improving positioning efficiency without complicating the control system.
4Device complexity
If all positioning parameters are displayed in one view, then the display is simple, but the accuracy of position determination is reduced
Solution Approach 1:
Positioning parameters are segmented into different partial views based on their spatial relationships, with each view dedicated to specific parameters. This segmentation improves measurement precision by allowing detailed examination of each parameter group without increasing display complexity.
Solution Approach 2:
The display uses multiple two-dimensional projections arranged in space to represent three-dimensional positioning parameters, achieving high position determination accuracy while maintaining a simple overall display arrangement through systematic layout organization.

AI summary
The invention relates to a method of presenting positioning information on a drilling unit of a rock drilling rig when drilling drill holes as a fan-like pattern. Further, the invention relates to a user interface and a rock drilling rig. A display device (25) presents the location and direction of the drilling unit (6) relative to the hole information and the fan plane. The display device shows the operator a display image (30) having at least two partial views (31a, 31b) on the basis of which the operator obtains information on all degrees of freedom relating to the positioning simultaneously. The operator controls the positioning by means of a user interface (29) comprising a display device and at least one control member (15) which are connected to a control unit (16).
