Field Access Priority Control for Conflicting Agricultural Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural machines often face conflicts when performing tasks in the same field, leading to inefficiencies and potential delays due to the lack of effective management systems for prioritizing access and scheduling.
Innovation Solution
A management system that utilizes a processor to assign priority levels to agricultural machines and workers, allowing machines with higher priority to access and perform tasks while lower-priority machines or workers can be instructed to stop or reschedule, ensuring efficient task completion based on predefined priority data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple agricultural machines perform tasks in the same field simultaneously, then productivity increases, but conflicts arise leading to reduced reliability and operational efficiency
Solution Approach 1:
The management system performs preliminary scheduling and conflict detection before agricultural machines enter the field. It assigns priority levels to different machines and tasks in advance, and preemptively resolves potential conflicts by coordinating access timing, thereby maintaining both high productivity and operational reliability
Solution Approach 2:
The management system acts as an intermediary between multiple agricultural machines and the field. It receives task requests from machines, evaluates conflicts based on priority data, and coordinates access by granting or denying entry permissions, thus enabling multiple machines to work efficiently without direct conflicts
2Reliability
If a management system coordinates multiple agricultural machines, then conflicts are reduced, but system complexity increases
Solution Approach 1:
The management system simplifies coordination by changing the parameter representation of machine attributes into discrete priority levels (e.g., high, medium, low). This parameter transformation enables straightforward conflict resolution rules without requiring complex real-time negotiations between machines
Solution Approach 2:
Each agricultural machine is equipped with the ability to self-report its task requirements and priority level to the management system. The system then autonomously makes access decisions based on predefined rules, reducing the need for complex inter-machine communication and manual coordination

AI summary
A management system manages access of agricultural machines to a field, and includes a processor configured or programmed to, while a first agricultural machine is performing an agricultural task in the field and if a conflict of agricultural tasks for the field exists between the first agricultural machine and a second agricultural machine, allow at least one of the first agricultural machine and the second agricultural machine determined based on priority data to perform the agricultural task for the field.
