Agricultural Implement Direction Control With Sensor-Actuator Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural implements towed by work vehicles face challenges in maintaining precise orientation and direction during field operations, leading to inefficiencies in tasks like planting and nutrient application.
Innovation Solution
A system comprising a work vehicle with a vehicle-based controller and an agricultural implement equipped with sensors and actuators, allowing for real-time adjustment of the implement's direction through communication between vehicle-based and implement-based controllers via ISOBUS Class 3 protocols, using valves and actuators to maintain desired operational parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual control of implement direction is used, then device complexity is reduced, but manufacturing precision and operational accuracy deteriorate
Solution Approach 1:
The system employs sensors to detect the implement's actual direction of travel and feeds this information back to the controller, which automatically adjusts the implement orientation to maintain the desired course, eliminating the need for manual intervention while ensuring high precision
Solution Approach 2:
The implement control system operates autonomously by self-monitoring its direction through sensors and self-correcting its orientation through automatic actuator control, freeing the operator from manual direction control tasks
2Productivity
If real-time direction adjustment is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The controller serves multiple functions by integrating both direction control and orientation maintenance capabilities, while sensors monitor both position and orientation parameters, reducing the need for separate dedicated systems and minimizing overall complexity
Solution Approach 2:
The system combines direction control and orientation maintenance into a single integrated control architecture, where the controller manages both actuators based on unified sensor input, simplifying the control structure while enabling real-time adjustments
3Measurement precision
If sensor-based monitoring is used, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The sensors are designed to monitor multiple parameters simultaneously (position, orientation, and direction of travel), reducing the total number of sensors needed while maintaining high measurement precision for all parameters
Solution Approach 2:
The system integrates sensor data processing into the existing controller architecture, combining measurement functions with control decision-making in a single processing unit, thereby minimizing additional complexity from sensor integration

AI summary
In one aspect, a system for controlling the direction of travel of agricultural implements may include a work vehicle having a vehicle-based controller configured to control an operation of a valve provided in operative association with the work vehicle. The system may also include an agricultural implement configured to be towed by the work vehicle. The implement may include a sensor configured to detect an operational parameter indicative of a direction of travel of the implement. The implement may also include an actuator configured to adjust the direction of travel of the implement, with the actuator being fluidly coupled to the valve such that the valve is configured to control an operation of the actuator. The implement may further include an implement-based controller configured to initiate control of the operation of the valve based on sensor data received from the sensor to adjust the direction of travel of the implement.
