Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to effectively switch operation targets between work machines in remote operations, failing to provide clear visualization of the positions and relative relationships of multiple work machines, making it difficult for operators to perform stable and reliable work.
Innovation Solution
A work support server that includes a first support processing element to recognize the positions of work machines and a second support processing element to display simultaneous images of the current and target machines on a display device, facilitating a clear understanding of their positions and relationships.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple fixed point cameras are installed to capture the entire work site in a bird's-eye manner, then the overall site visibility is improved, but the ability to clearly recognize specific work machine positions and relative relationships deteriorates
Solution Approach 1:
The system segments the work site monitoring into multiple functional layers: overview monitoring by fixed cameras and detailed position tracking by mobile cameras mounted on work machines. This segmentation allows simultaneous achievement of broad coverage and precise position recognition for specific machines.
Solution Approach 2:
The information presentation device acts as an intermediary that synthesizes data from multiple fixed cameras and mobile cameras, then presents integrated information including work machine positions overlaid on bird's-eye views. This intermediary processing resolves the contradiction by combining both wide-area coverage and precise position data in a unified display.
2Device complexity
If the information presentation device displays only general site overview images, then the system complexity is reduced, but the operator's ability to grasp specific work machine positions and surrounding situations deteriorates
Solution Approach 1:
The information presentation device dynamically adapts its display content based on operational context. When operation target switching is detected, the system automatically switches from general overview display to detailed position display showing both current and target machine positions and surrounding situations, thereby providing necessary information without requiring permanent complex display capabilities.
Solution Approach 2:
The system performs preliminary detection of operation target switching intentions, then proactively prepares and presents relevant position information before the actual switching occurs. This allows the operator to anticipate and plan the switching operation with full awareness of target machine positions and surrounding conditions.
3Loss of information
If the system provides detailed information about work machine positions and relationships, then the operator's situational awareness is improved, but the ease of operation deteriorates due to increased information complexity
Solution Approach 1:
The information presentation device applies local quality by providing detailed position and situation information only when and where needed - specifically during operation target switching operations. During normal operations, the display maintains simplicity. This localized information enhancement improves situational awareness during critical moments without permanently complicating the interface.

AI summary
A work support server 10 according to the present invention supports work in such a manner that a plurality of work machines 40 to be operated can be selectively remotely operated in response to an operation to be performed for a remote operation apparatus 20 including an image output device 221. A first support processing element 121 in the work support server 10 recognizes a position of each of the work machines 40, and a second support processing element 122 displays, when an operation target of the remote operation apparatus 20 is switched from a first work machine 40a to a second work machine 40b, an image including respective positions of the first work machine 40a and the second work machine 40b simultaneously captured on the image output device 221.
