Agricultural Route Planning for Soil Compaction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route planning methods for agricultural areas fail to balance soil protection with practicality, leading to excessive fuel costs and soil compaction due to unnecessary detours aimed at avoiding repeated traversals, which are not effective in measuring soil compaction caused by agricultural processing machines.
Innovation Solution
A method that estimates soil compaction spatially and updates this data for each cultivation, considering machine and soil parameters to plan routes that avoid excessive compaction while minimizing detours, allowing for flexible route adjustments based on vehicle load and soil conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If detours are made to avoid re-routing areas already worked during a first pass, then soil compaction is reduced, but fuel costs increase and the proportion of area affected by compaction rises
Solution Approach 1:
The system dynamically adjusts route planning based on real-time soil compaction data and machine parameters. Instead of static avoidance of all previously worked areas, the planner adapts routes considering current soil conditions, machine weight, and operational requirements, optimizing the balance between soil protection and fuel efficiency
Solution Approach 2:
The system changes multiple parameters simultaneously including machine weight (by considering unloading points), soil compaction thresholds, and route geometry. By adjusting these parameters dynamically, the system can determine when detours are necessary versus when direct routing is acceptable based on current soil conditions
2Object-affected harmful factors
If detours are made to avoid re-routing areas already worked, then soil compaction is reduced, but the proportion of area affected by compaction from previous passes rises disproportionately
Solution Approach 1:
The system applies different routing strategies to different areas based on local soil conditions. Instead of uniform avoidance of all previously worked areas, it identifies specific zones where compaction risk is high versus areas where repeated passes are acceptable, applying localized route adjustments rather than global detours
3Productivity
If multiple passes are required on the same area, then cultivation completeness is improved, but soil compaction increases significantly
Solution Approach 1:
The system performs preliminary route planning that identifies and marks areas requiring multiple passes before actual cultivation begins. By pre-planning which areas will need repeated attention and scheduling appropriate intervals between passes, the system minimizes unnecessary compaction while ensuring complete cultivation coverage
Solution Approach 2:
The system implements periodic re-assessment of soil compaction levels between passes. By monitoring soil conditions and machine parameters periodically, it can determine optimal timing for subsequent passes, allowing soil recovery periods that reduce cumulative compaction effects while maintaining cultivation completeness

AI summary
A method for planning a route (3, 6, 7) for working an agricultural area (1) by a mobile machine (2) comprises the steps of estimating, at least horizontally, spatially resolved soil compaction resulting from previous working of the area by the same or a different machine (S10), and taking into account the determined soil compaction when determining the course of a route for the intended working of the area by the machine (S4-S9).
