Shared Work Area Data for Multi-Device Field Route Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work devices require preparatory work when switching between different devices in the same field, necessitating redundant effort and inefficiency in autonomous traveling.
Innovation Solution
A work area management system that stores and shares first area information for a first work device, allowing a second work device to use the same area information to perform work, reducing the need for redundant preparatory work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a work device travels circumferentially around the work area to identify the work area, then the work area can be determined, but preparatory work must be repeated for each different work device
Solution Approach 1:
The patent merges the work area identification function into a shared database that stores work area information independently of specific work devices. Multiple work devices access and share the same work area data, eliminating the need for each device to perform separate circumferential traversal for area identification.
Solution Approach 2:
The work area is identified and stored in advance in a database before actual work begins. This preliminary identification allows subsequent work devices to access pre-stored area information without performing redundant traversal, saving time while maintaining accurate area boundaries.
2Extent of automation
If each work device performs independent preparatory work to identify the work area, then device autonomy is maintained, but workload and inefficiency increase
Solution Approach 1:
The patent creates a universal work area database that serves multiple work devices simultaneously. The database stores work area information in a device-agnostic format, allowing any work device to access and utilize the same area data, thereby maintaining autonomy while improving overall system productivity through shared information.

AI summary
A work area management method includes storing first area information that represents a first work area that determines a first work route along which a first work device moves to perform a first work in a field, and that is determined on the basis of a positioning position of the first work device. The work area management method also includes outputting the first area information as information that represents an area for determining a second work route along which a second work device different from the first work device moves to perform a second work in the field. The outputting the first area information may include outputting warning information representing that the first area information is unsuitable for determining the second work route when the first area information does not satisfy a predetermined condition.
