Work Screen Region Display for Reference Station Position Drift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work screen display systems for autonomous vehicle travel lack operability, as they do not effectively indicate deviations in the position of specific regions displayed on the user interface, which can occur due to differences in positioning correction information from reference stations.
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 on the display unit. The display mode varies based on whether the first and second reference stations are identical or not, allowing users to easily determine potential deviations and select the appropriate region for autonomous travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning correction information is supplied from different reference stations, then the specific region can be determined, but deviation may occur between the position of the specific region indication section and the actual position of the work vehicle
Solution Approach 1:
The display control unit changes the color or visual appearance of the specific region indication section based on whether the first reference station and second reference station are identical. When they are identical, one color is displayed; when they differ, another color is displayed. This allows users to quickly identify potential position deviations without complex data processing, resolving the contradiction by providing visual feedback that maintains both position accuracy and reliability awareness.
Solution Approach 2:
The system provides visual feedback through the display control unit that indicates whether the reference stations match. This feedback mechanism allows users to understand the reliability of the position information and make informed decisions about autonomous travel operations, thereby maintaining both measurement precision and reliability.
2Ease of operation
If the display screen shows detailed operation sections and status information, then user operability is improved, but the screen complexity increases
Solution Approach 1:
The display control unit applies different visual qualities to different parts of the display screen. The specific region indication section is highlighted with distinctive visual characteristics (such as color changes) that differ from other elements on the screen. This allows important information to stand out without requiring all screen elements to be equally complex, thereby improving ease of operation while controlling overall screen complexity.

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.
