Spraying Support System for Agricultural Working Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spraying systems for working machines lack an efficient method to create and implement spraying plans that account for field-specific information and spraying substance distribution, leading to suboptimal fertilizer application and increased operational complexity.
Innovation Solution
A spraying support system comprising a support device that creates a spraying plan based on field information and spraying information, a plan obtainer device to obtain this plan, and a spraying controller device to adjust the sprayer's operation accordingly, ensuring optimal fertilizer distribution and reduced operational complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a spraying plan is created based on field information and spraying information, then spraying precision is improved, but device complexity increases
Solution Approach 1:
The system divides the spraying operation into distinct segments: a support device creates a spraying plan based on field information, a plan obtainer device retrieves the plan, and a spraying controller device executes control. This segmentation allows each component to specialize in one function, improving overall spraying precision while managing complexity through modular design.
Solution Approach 2:
The spraying plan acts as an intermediary data structure that mediates between field information/spraying information and the actual sprayer control. This intermediary layer organizes and structures the information flow, enabling precise control without requiring direct complex interactions between all system components.
2Manufacturing precision
If spraying amount is adjusted based on field contours and areas, then fertilizer application quality is improved, but operational complexity increases
Solution Approach 1:
The support device creates the spraying plan in advance, performing preliminary calculations and adjustments based on field contours and areas before actual spraying begins. This preliminary action pre-determines the optimal spraying amounts for different field regions, improving fertilizer application quality while simplifying real-time operation.
Solution Approach 2:
The system performs self-adjustment through automated control. The spraying controller device automatically adjusts spraying amounts based on the pre-created plan without requiring manual intervention for each adjustment, thereby improving application quality while maintaining ease of operation through automation.
3Productivity
If automated spraying control is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The spraying controller device serves multiple functions: it receives the spraying plan, interprets the field information, adjusts spraying amounts dynamically, and controls the sprayer operation. This multi-functionality consolidates control tasks into a single device, improving productivity while managing complexity through functional integration.

AI summary
A spraying support system for a working machine, includes: a support device including a plan creator portion to create a spraying plan representing a relation between field information relating to a field to which spray substance is sprayed and spraying information including spraying amount of the spray substance; a plan obtainer device provided to a working machine having a sprayer device to spray the spray substance and configured to obtain the spraying plan created by the plan creator portion; and a spraying controller device to control a sprayer portion of the sprayer device based on the spraying information of the spraying plan obtained by the plan obtainer device.
