Solution Overview

Problem

Conventional field registration methods for automated agricultural machinery are inefficient when position information cannot be acquired during the registration process, leading to decreased work efficiency due to the need for re-traveling and potential communication losses or lowered positioning accuracy.

Innovation Solution

A field registration method that acquires and records position information of a work vehicle, temporarily stops recording when information cannot be acquired, notifies the user, and registers the field based on the acquired data, utilizing an acquisition processing unit, recording processing unit, notification processing unit, and registration processing unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the work vehicle travels around the outer periphery of the field to acquire position information, then the field shape can be recognized and registered, but the work efficiency deteriorates when position information cannot be acquired due to communication loss or positioning accuracy issues

Engineering Contradiction:
Improveposition information acquisition reliabilityVSAvoidwork efficiency of registration work
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary actions by continuously monitoring communication status and positioning accuracy before complete loss occurs. When position information cannot be acquired, the system has already prepared alternative approaches (such as using previously acquired position information or switching to different positioning methods) to avoid complete registration failure, thereby maintaining work efficiency while ensuring reliable field registration.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If the work vehicle is restored to acquire position information again after loss, then complete field registration can be achieved, but the registration process time increases significantly

Engineering Contradiction:
Improvefield registration completenessVSAvoidregistration process time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system maintains continuity of useful action by continuously acquiring and storing position information throughout the field periphery traversal, even when temporary communication loss or positioning accuracy issues occur. The registration process can continue using accumulated position information without requiring complete re-traversal, thereby achieving complete field registration while minimizing registration process time.

Inventive Principle:
Principle #20Continuity of useful action

3Loss of information

If the position information recording is continuously performed, then complete field trajectory is captured, but system resources are wasted when communication is lost or positioning accuracy is low

Engineering Contradiction:
Improveposition information completenessVSAvoidsystem resource consumption
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The system applies partial action by selectively recording position information based on quality criteria. When communication status is normal and positioning accuracy meets requirements, position information is recorded. When communication is lost or accuracy is insufficient, recording is suspended or marked, avoiding waste of system resources while maintaining completeness of valid position information for field registration.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

[Problem] To provide a field registration method, a field registration system, and a field registration program capable of improving work efficiency of a registration work of registering a field. [Solution] An acquisition processing unit acquires position information of a work vehicle traveling in a predetermined area in response to a traveling operation by an operator. A recording processing unit records the position information, as a traveling trajectory of the work vehicle, and temporarily stops recording processing of recording the position information, in a case where the work vehicle is brought to a state in which the position information cannot be acquired during traveling. A notification processing unit notifies the operator of information indicating that the recording processing is temporarily stopped. A setting processing unit registers a field, based on the position information.
