Remote Work Machine Operation With Image Suitability Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation systems for construction machines may be operated without displaying an image suitable for remote operation, leading to potential safety hazards.
Innovation Solution
A remote operation system for work machines that includes an imaging device, communication device, display device, and remote operation device, which limits operation when an unsuitable image is displayed, ensuring a suitable image is always visible for safe remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote operation is allowed without image display verification, then operational flexibility and ease of operation are improved, but safety and reliability deteriorate due to potential accidents from unsuitable images
Solution Approach 1:
The system performs preliminary verification of image suitability before allowing remote operation to commence. The determination unit checks whether the image meets predetermined criteria (such as displaying the work machine and surrounding area) before the remote operation unit is activated, ensuring safety conditions are met in advance
Solution Approach 2:
The system continuously monitors image quality during remote operation and provides feedback to the determination unit. When the image becomes unsuitable (e.g., obscured by snow or smoke), the system automatically detects this change and terminates the remote operation, creating a closed-loop safety mechanism
2Reliability
If image quality monitoring and operation limitation are implemented, then safety and reliability are improved, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The determination unit serves multiple functions: it evaluates image suitability, makes operation permission decisions, and terminates operations when conditions worsen. This multi-functional approach consolidates what could be separate complex systems into a single integrated unit
Solution Approach 2:
The system automatically monitors image quality and makes its own determination about operation safety without requiring external intervention. The remote operation unit self-terminates when the determination unit finds the image unsuitable, creating a self-regulating safety mechanism that reduces the need for additional complex control systems
