Remote Travel Control for Agricultural Machine Permitted Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural machines equipped with remote manipulation systems lack effective mechanisms to prevent unintended travel in unauthorized areas or states, leading to potential accidents and inefficiencies in agricultural operations.
Innovation Solution
A travel control system that includes a storage for permitted area positions and a controller capable of disabling remote manipulation when the agricultural machine's state or implement does not meet the conditions for permitted travel, ensuring safe and controlled operation within designated areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If remote manipulation is enabled for agricultural machines, then operational flexibility and productivity are improved, but safety risks increase due to unintended travel in unauthorized areas or states
Solution Approach 1:
The system performs preliminary actions by pre-defining permitted areas and travel conditions before remote manipulation begins. The controller stores position information of permitted areas and predetermined conditions, then proactively checks whether the agricultural machine's current state and location satisfy these conditions before allowing remote manipulation commands to execute, preventing unintended travel in advance
Solution Approach 2:
The system implements continuous feedback by monitoring the agricultural machine's real-time state (position, implement attachment status, travel conditions) and comparing it against the stored permitted areas and predetermined conditions. When the machine's state deviates from permitted parameters, the system provides feedback by disabling remote manipulation and notifying the operator, ensuring safety through ongoing verification
2Reliability
If comprehensive travel restrictions and condition checks are implemented, then safety is improved, but system complexity increases
Solution Approach 1:
The controller serves multiple functions: it manages remote manipulation commands, stores permitted area position information, monitors agricultural machine state, evaluates travel conditions, and disables remote manipulation when conditions are not met. By consolidating these diverse functions into a single controller, the system achieves comprehensive safety checks without proportionally increasing overall system complexity
Solution Approach 2:
The system performs self-verification by automatically checking whether the agricultural machine's current state and location satisfy the predetermined conditions for remote manipulation. The controller autonomously evaluates travel conditions, compares real-time data against stored permitted areas, and makes decisions to enable or disable remote manipulation without requiring external intervention, reducing the burden on operators and simplifying the user interface

AI summary
A travel control system for an agricultural machine capable of performing remotely-manipulated traveling including a storage to store a position of a permitted area in which the remotely-manipulated traveling is permitted conditionally, and a controller operable in a remote manipulation mode in which travel of the agricultural machine is controlled by remote manipulation. In the remote manipulation mode, when a state of the agricultural machine does not satisfy a condition required for the remotely-manipulated traveling in the permitted area, the controller is configured or programmed to disable a remote manipulation to cause the agricultural machine to travel in the permitted area.
