Slewing Angle Visual Alignment for Remote Working Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote control of working machines faces challenges in matching the slewing angle of the upper slewing body with the target slewing angle due to limited visual information, making it difficult for operators to align the two correctly.
Innovation Solution
A working machine control device equipped with a camera on the upper slewing body to capture images of the lower travelling body, a display unit to superimpose a target image on the captured image, and a controller to assist in aligning the slewing angle, allowing operators to easily match the slewing angle with the target angle through visual and notification feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote control is implemented, then operator safety and accessibility are improved, but visual information availability deteriorates
Solution Approach 1:
The system creates a virtual copy of the physical display by projecting the lower travelling body image and target position onto a virtual display that matches the camera's field of view. This allows the remote operator to see the target position in the same visual frame as the actual machinery, restoring spatial awareness and visual information availability while maintaining remote control safety benefits
2Ease of operation
If remote control is implemented, then operator accessibility is improved, but slewing angle matching accuracy deteriorates
Solution Approach 1:
The system provides real-time visual feedback by displaying the lower travelling body image with the target position superimposed on the same screen. The target position moves dynamically as the upper slewing body rotates, giving the operator immediate visual feedback on whether the slewing angle is correct, thereby maintaining high matching accuracy despite remote operation
Solution Approach 2:
By creating a virtual display that replicates the camera's field of view and superimposing the target position onto it, the system allows the remote operator to visually align the upper slewing body with the target with the same ease as if physically present, thereby maintaining slewing angle matching accuracy while enabling remote operation

AI summary
A working machine control device includes a camera that obtains a captured image by imaging a particular part that is a part of a lower travelling body, and a controller, in which the controller includes a setting unit that sets a target slewing angle of an upper slewing body with respect to the lower travelling body, and a display control unit that causes a display unit to display a display screen in which a target image indicating a target position of the particular part is displayed in a superimposed manner at a position on the captured image, the position being where the particular part is displayed when a slewing angle of the upper slewing body with respect to the lower travelling body reaches the target slewing angle.
