Work Screen Region Display for Reference Station Mismatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work screen display systems for autonomous vehicle travel lack operability, particularly in determining the specific region for autonomous travel due to potential deviations between reference stations, which can confuse users and hinder accurate region selection.
Innovation Solution
The system includes a position information obtaining unit, a region shape determination unit, and a display control unit that displays a specific region indication section in varying modes based on the identity of reference stations, allowing users to easily identify and select the correct region for autonomous travel by distinguishing between identical and non-identical reference stations, and controls map image display magnification and centering based on operation states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system displays the specific region indication section using a single fixed display mode, then the display structure is simple, but the user cannot easily identify potential deviations between reference stations reducing operability
Solution Approach 1:
The display control unit dynamically changes the display mode of the specific region indication section based on whether the first reference station and second reference station are identical. When stations differ, the system switches to a second display mode that highlights potential deviations, making the display adaptive to operational context rather than static
Solution Approach 2:
The system uses different display modes (potentially involving color or visual style changes) to indicate the identity relationship between reference stations. The second display mode for non-identical stations provides visual differentiation that helps users quickly identify potential positioning deviations
2Ease of operation
If the system uses different display modes for identical and non-identical reference stations, then user operability is improved, but the display control logic becomes more complex
Solution Approach 1:
The display control unit receives feedback about the identity relationship between reference stations and adjusts the display mode accordingly. This feedback mechanism automatically informs the user about potential deviations without requiring manual configuration or complex interpretation
3Reliability
If the system does not distinguish between different reference station scenarios, then the display is simple, but users may be confused by potential deviations between position information and specific region indication
Solution Approach 1:
The system employs visual differentiation through different display modes to indicate whether reference stations are identical or different. This visual cue system helps users understand the reliability of position information without adding complex technical infrastructure

AI summary
A work screen display system including a position information obtaining unit for obtaining position information on a work vehicle based on positioning correction information supplied from a first reference station; a region shape determination unit for determining a shape of a specific region where the work vehicle performs autonomous travel, based on positioning correction information supplied from a second reference station; and a display control unit for displaying, on a display unit, a specific region indication section indicating the specific region determined by the region shape determination unit. The display control unit displays the specific region indication section in a display mode that varies between a case where the first and second reference stations are identical and a case where the first and second reference stations are not identical.
