Automated Check Strip Control for Precise Field Yield Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural systems face challenges in accurately implementing and analyzing check strip operations, as they often require manual intervention and pre-definition of check strip locations, leading to potential misalignment and reduced effectiveness in yield comparison.
Innovation Solution
An agricultural machine system that dynamically senses and controls check strip operations, detecting the start and end locations and dimensions of check strips during operation, allowing for precise execution and post-harvest analysis without pre-definition, using a control system that includes a check strip trigger detector, start and end location identifiers, and a check strip control system to manage the transition between standard and check strip operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If check strip locations are pre-defined, then the operation can be planned in advance, but misalignment occurs during actual execution reducing effectiveness
Solution Approach 1:
The system performs preliminary actions by pre-defining check strip locations and parameters before field operations. The controller is programmed with check strip location data beforehand, allowing the agricultural operation to automatically switch to check strip mode when reaching those pre-defined locations, ensuring both advance planning and accurate execution
Solution Approach 2:
The system uses feedback from GPS/location sensors to continuously monitor the machine's position and automatically adjust operations. When the machine reaches a pre-defined check strip location, the system receives location feedback and automatically switches between check strip and normal operations, eliminating manual intervention and ensuring precise alignment
2Ease of operation
If manual intervention is required to change operations in check strips, then flexibility is maintained, but accuracy and consistency are reduced
Solution Approach 1:
The system performs self-service by automatically detecting when the agricultural machine enters and exits check strip areas using GPS/location sensors. The controller autonomously switches between check strip operations and normal operations without requiring manual operator intervention, ensuring consistent and repeatable operations while maintaining the ability to change parameters
Solution Approach 2:
The system replaces manual mechanical control with an automated electronic control system. The controller uses electronic signals from location sensors to automatically adjust operational parameters, substituting human manual intervention with an automated feedback-based control mechanism that improves consistency and precision
3Adaptability or versatility
If check strip operations are manually controlled, then adaptability is possible, but time consumption and productivity are reduced
Solution Approach 1:
The system implements dynamic operation by allowing real-time switching between check strip and normal operational modes based on the machine's location. The controller dynamically adjusts operational parameters (such as seed rate, spray rate, or harvesting intensity) automatically as the machine enters and exits check strip areas, maintaining adaptability while eliminating manual intervention time
Solution Approach 2:
The system ensures continuous useful action by automatically managing check strip operations without interrupting the overall field operation. The transitional periods for manual intervention are eliminated, allowing the machine to maintain continuous operation throughout the field while still performing check strip comparisons, thereby improving productivity
Data Source
AI summary
An agricultural machine performs a prescribed agricultural operation in a field. The machine is controlled to change the agricultural operation to a check strip operation. A location where the check strip operation is commenced is sensed and a location where the check strip operation ceases is also sensed. A dimension of the check strip, and its location, are stored.
