Fertilizer Spreader Master Control System for Multi-Actuator Setpoint Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fertilizer spreader systems can only activate one control system at a time, limiting their ability to adapt to various conditions such as wind, border spreading, and section control, which affects the generation of an ideal spread pattern.
Innovation Solution
A method that utilizes multiple systems to generate a spread pattern by specifying setpoint specifications for actuators, with a master system prioritizing or combining these specifications based on predetermined and measurement parameters, such as wind direction and slope, to ensure optimal fertilizer distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only a single control system is active at a time, then system complexity is reduced and control is simplified, but the ability to adapt to various conditions (wind, border spreading, section control) is limited
Solution Approach 1:
The master control system serves multiple functions by receiving setpoint specifications from different control systems (wind control, border spreading, section control) and determining a unified control command that adapts to various operating conditions. This multi-functional approach enables the system to handle diverse scenarios without requiring separate dedicated control systems for each condition.
Solution Approach 2:
Multiple control systems (wind control, border spreading, section control) are merged into a single master control system that integrates their setpoint specifications. The master system combines these inputs and generates a unified control command, allowing the fertilizer spreader to respond to multiple conditions simultaneously while maintaining manageable system complexity through centralized coordination.
2Adaptability or versatility
If multiple control systems are activated simultaneously, then adaptability to various conditions improves, but conflicts and overlaps in setpoint specifications occur
Solution Approach 1:
Instead of having each control system independently control actuators and risk conflicts, the approach is inverted: all control systems submit their setpoint specifications to a master system that determines the final control command. This inversion of control authority eliminates conflicts by establishing a single decision-making point that reconciles all inputs before actuator control.
Solution Approach 2:
The master control system acts as an intermediary between multiple control systems and the actuators. It receives setpoint specifications from wind control, border spreading, and section control systems, processes these inputs according to priority rules and current operating conditions, and generates a unified control command that resolves any conflicts before execution.
3Reliability
If a master system prioritizes one control system over others, then control conflicts are resolved, but the ability to utilize multiple systems' setpoint specifications is reduced
Solution Approach 1:
The master control system applies different priority levels and weighting factors to different control systems based on local conditions. For example, wind control may be given higher priority during high wind conditions, while border spreading control takes precedence near field boundaries. This localized quality adjustment allows the system to utilize multiple control systems' specifications while resolving conflicts through context-dependent prioritization.

AI summary
The invention relates to a method and a fertilizer spreader for generating a spreading pattern, wherein several systems (1a-1f) specify at least one setpoint (S1a-f, S2a-f, S3a-f) for controlling/regulating actuators (1a-1f) to generate a corresponding spreading pattern, wherein a master system (2) either selects one of the several systems (1a-1f) and gives priority to this system (1a-1f) in order to control the actuators (1a-1f) depending on its setpoint specifications (S1a-f, S2a-f, S3a-f) or selects several systems (1a-1f) and calculates the setpoint specifications (S1a-f, S2a-f, S3a-f) of the selected systems (1a-1f) for the respective actuators (1a-1f).
