Information-Sharing System for Crane Work Range Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crane operation support systems cannot display information of the entire work range beyond the imaging area of a camera and share such information among multiple operators.
Innovation Solution
An information-sharing system that includes a control apparatus, displays, and an information input section, which acquires camera images and coordinates, displays map information with camera images superimposed, and adjusts scales and zoom ratios synchronously across multiple displays to cover the entire work range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a camera is used to capture the work site, then real-time visual information is provided, but the entire work range cannot be displayed when the work range exceeds the camera's imaging area
Solution Approach 1:
The patent merges the camera image display with map information display into a unified interface. The map shows the entire work range while the camera image is overlaid or positioned on the map, combining the comprehensive coverage of the map with the real-time visual feedback of the camera to display complete work range information.
Solution Approach 2:
The patent introduces map information as an intermediary element between the camera and the operator. The map serves as a mediator that contextualizes the camera's limited field of view within the broader work range, allowing operators to understand both the immediate camera view and the overall work area simultaneously.
2Adaptability or versatility
If multiple operators need to share information, then collaboration is improved, but maintaining synchronized display across multiple devices increases system complexity
Solution Approach 1:
The patent implements a universal display system where multiple displays (portable terminals and in-vehicle displays) access and show the same standardized information interface. This multi-functional approach allows any operator with any display device to view and interact with the same work range information and camera feeds, enabling seamless information sharing without requiring device-specific implementations.
3Ease of operation
If the scale of map information is changed on one display, then viewing flexibility is improved, but other displays must also update to maintain synchronized view
Solution Approach 1:
The patent implements a feedback mechanism where scale adjustment operations on any display are transmitted to the control device, which then sends updated scale parameters back to all other displays. This feedback loop ensures that when one operator adjusts the map scale on their portable terminal or in-vehicle display, all other operators' displays automatically update to maintain the same synchronized view, preserving operational consistency across the team.
