Sprayer Auto-Travel Stop Reservation for Remote Field Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing automatic traveling systems for work vehicles, issuing a travel stop instruction while the vehicle is performing spraying work requires the operator to enter the sprayed area, reducing work efficiency due to the need for countermeasures to avoid exposure to spray materials.
Innovation Solution
Implementing temporary stop processing and stop reservation processing to allow the work vehicle to pause and resume travel based on predefined conditions, enabling remote control and minimizing the need for operators to enter sprayed areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the work vehicle stops at the current position when a travel stop instruction is issued during spraying work, then the operator can control the work vehicle remotely, but the operator must enter the sprayed area which reduces work efficiency
Solution Approach 1:
The system performs preliminary action by reserving a stop position in advance before the vehicle reaches it. When a stop instruction is issued during spraying, instead of stopping immediately at the current position (which would require operator entry into sprayed area), the vehicle continues to a pre-calculated stop position that is outside the sprayed area, thereby maintaining both remote control capability and work efficiency
2Productivity
If the work vehicle continues traveling without stopping when a travel stop instruction is issued, then work efficiency is maintained, but the operator cannot intervene or monitor the work closely
Solution Approach 1:
The system implements feedback by notifying the operator when the vehicle approaches the reserved stop position. This allows the operator to monitor the work closely and know when intervention may be needed, while the vehicle maintains its travel and spraying operations, thus preserving both work efficiency and operator intervention capability

AI summary
The automatic traveling method includes: causing a sprayer 1 to travel automatically along a target route in a field; executing temporary stop processing; and executing stop reservation processing. The temporary stop processing is processing to stop the sprayer at a current position in a mode in which travel of the sprayer can be resumed in the case where a temporary stop condition is satisfied during automatic travel of the sprayer. The stop reservation processing is processing to cause the sprayer to travel and thereafter stop the sprayer in a state where the travel of the sprayer can be resumed in the case where a stop reservation condition is satisfied during the automatic travel of the sprayer.
