Spray Coefficient Mapping for Uniform Crop Spraying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Farmers cannot accurately determine the amount of chemical sprayed on specific areas of a target work area using plant protection devices, leading to excessive or insufficient spraying, resulting in agrochemical residues and inefficiencies.
Innovation Solution
A method and system that acquire a spray coefficient by measuring spray flow rate and moving speed, then use color information to visually represent spray amounts on an electronic map, allowing for real-time adjustment of spraying operations to ensure uniform coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If farmers apply chemical to crop by plant protection device without determining spray amount, then spraying operation can be completed, but excessive or insufficient spraying occurs causing agrochemical residues and waste
Solution Approach 1:
The system continuously monitors spray flow rate and moving speed during operation, calculates spray coefficient in real-time, and provides feedback through color-coded visualization on electronic map. This allows farmers to adjust spraying parameters dynamically to achieve uniform coverage and avoid excessive or insufficient spraying.
Solution Approach 2:
The patent uses color information (e.g., green for adequate spray, yellow for insufficient spray, red for excessive spray) to visually represent spray coefficients on an electronic map. This color-coded feedback system enables farmers to intuitively identify areas requiring adjustment without complex data interpretation.
2Speed
If farmers spray chemical without real-time monitoring, then operation speed can be maintained, but uniform coverage cannot be ensured
Solution Approach 1:
The system calculates spray coefficient based on real-time spray flow rate and moving speed data, providing continuous feedback that allows farmers to maintain operating speed while adjusting spray parameters to achieve uniform coverage. The color-coded map shows coverage quality without requiring speed reduction.
3Reliability
If farmers increase spray amount to ensure coverage, then insufficient spraying is avoided, but excessive spraying and agrochemical residues occur
Solution Approach 1:
The system dynamically adjusts spray parameters based on calculated spray coefficients, allowing farmers to optimize spray amount for each specific area. By using color-coded feedback to identify adequate, insufficient, or excessive spray zones, farmers can reduce overall chemical usage while maintaining reliable coverage where needed.
