1Productivity
If conventional travel route generation devices are used, then basic route generation is possible, but the ability to efficiently generate optimal routes considering field shape and headland information is lacking, leading to collision risks and inefficient work planning
Solution Approach 1:
The system performs preliminary actions by pre-storing field shape information and headland information in memory before route generation. The circuitry uses this pre-stored data to proactively generate optimal travel routes that avoid collisions, rather than reacting to collision risks during actual work. This preliminary preparation of spatial data enables efficient work planning while ensuring safety.
Solution Approach 2:
The display unit provides visual feedback by showing the generated travel route overlaid on the field shape, along with work status information. This feedback mechanism allows operators to verify route optimality and make adjustments if needed, improving work planning efficiency while maintaining collision avoidance through continuous monitoring and adjustment based on displayed information.
2Productivity
If detailed field shape information and headland information are stored and processed, then optimal route generation is achieved, but device complexity increases
Solution Approach 1:
The circuitry performs multiple functions using the stored field shape information and headland information: it generates optimal travel routes, estimates work status, and provides collision detection. By making the data storage and processing system multi-functional, the patent achieves route optimization without proportionally increasing device complexity, as the same infrastructure serves multiple purposes.
Solution Approach 2:
The display unit automatically presents the generated travel route and work status information without requiring additional manual processing or intervention. The system serves itself by autonomously utilizing the stored field data to generate, evaluate, and display optimal routes, reducing the operational complexity despite the detailed data processing required.
