Agricultural Machine Map Control for Rapid Parameter Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map-based control systems for agricultural machinery require complex and time-consuming updates when operating points exceed the currently traversed range, leading to suboptimal optimization of influencing factors like grain loss.
Innovation Solution
An agricultural working machine with a map-based control system that converts instantaneous operating points into quasi-stationary points, updating characteristic maps by overwriting initial operating points and recalculating control curves, allowing for simplified and accelerated map updates during harvesting operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If map updates are performed by selectively approaching operating points outside the currently traversed range, then the map coverage is expanded, but the optimization process becomes more complicated and requires active operator intervention
Solution Approach 1:
The system automatically determines when the current operating point is outside the traversed range and autonomously updates the map by selecting and approaching relevant operating points, eliminating the need for active operator intervention while maintaining comprehensive map coverage
Solution Approach 2:
The system pre-determines the traversed range and proactively identifies operating points outside this range before they become problematic, allowing the map to be updated in advance rather than reactively, simplifying the overall optimization process
2Adaptability or versatility
If the current operating point is outside the currently traversed range of the map, then map coverage is incomplete, but the characteristic curves outside this range do not accurately reflect actual relationships
Solution Approach 1:
The system dynamically adjusts the traversed range based on the current operating point and automatically updates the map by approaching new operating points only when necessary, ensuring that characteristic curves are maintained with high accuracy within the actual traversed range while expanding coverage as needed
Solution Approach 2:
The system continuously monitors the current operating point and compares it against the traversed range, using this feedback to determine when map updates are needed and to selectively approach operating points that will improve coverage without compromising the accuracy of existing characteristic curves
