Remote Worksite Interface for Correct Machine Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators using remote operation devices may mistakenly identify which work machine to operate when multiple work machines of the same model and manufacturer are displayed simultaneously, leading to inappropriate operation modes.
Innovation Solution
A work assist server that outputs a work-site birds-eye image and determines whether a work machine in the image is the connection-target work machine by comparing its image coordinate position with its real spatial position, and displays a sign image to indicate the correct work machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple work machines of the same model are displayed simultaneously on the output interface, then the operator can monitor all machines, but the operator may mistakenly identify which work machine to operate
Solution Approach 1:
The patent applies visual differentiation by displaying sign images with different colors or patterns on the output interface. The first sign image indicates the connection-target work machine while the second sign image indicates other work machines, enabling the operator to visually distinguish which machine should be operated among multiple displayed machines of the same model
Solution Approach 2:
The patent introduces sign images as intermediary visual indicators between the work machines and the operator. These sign images serve as mediators that convey information about the operational status and identity of each work machine, helping the operator correctly identify the connection-target machine without confusion
2Ease of operation
If no visual indicator is provided to distinguish the connection-target work machine, then the interface remains simple, but the operator cannot easily recognize which work machine is to be operated
Solution Approach 1:
The patent uses visual differentiation through sign images displayed on the output interface. The first sign image (indicating connection-target machine) and second sign image (indicating other machines) provide clear visual cues that enhance ease of operation without requiring complex interface changes
Solution Approach 2:
The patent segments the visual information by providing distinct sign images for different work machines. Each sign image is separately displayed to indicate the specific status or identity of each machine, allowing the operator to easily identify the connection-target machine among multiple displayed machines

AI summary
Provided is a server and a system that can assist an operator in recognizing whether or not a work machine in a work-site birds-eye image output on an output interface constituting a remote operation device is subject to remote operation by the remote operation device. According to the captured image acquired through the image pickup device C, when a work machine 40 is in the work-site birds-eye image that is output on an output interface 220 constituting a remote operation device 20, whether or not the work machine 40 is a connection-target work machine is determined. If the determination result is positive, a first sign image ID1 associated with an actual machine image Q2 that represents the work machine 40 in the work-site birds-eye image is displayed on the output interface 220 of the remote operation device 20.
