Crane Remote Terminal Display for Direction and Speed Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote operation terminals for work vehicles, such as cranes, lack sufficient information display, leading to reduced operability and increased operator burden, as they only show the movement direction of the hook without providing comprehensive information about movement speed and other critical parameters.
Innovation Solution
A remote operation terminal that calculates and displays a directed line segment representing the movement direction and speed of the work apparatus based on the manipulation direction and amount, with adjustable display modes for load factors and obstacle presence, using a terminal-side control apparatus and display apparatus to enhance visibility and operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only the movement direction of the hook is displayed, then the display is simple and clear, but the information content is insufficient for comfortable operation
Solution Approach 1:
The patent transforms the display from a one-dimensional arrow indicator to a two-dimensional directed line segment that simultaneously encodes direction and speed magnitude through its geometric properties (length and orientation), allowing more information to be conveyed without increasing display element count
Solution Approach 2:
The patent changes the parameter representation by using the length of the line segment to encode speed magnitude and the orientation to encode direction, transforming qualitative directional information into quantitative vector information that conveys both direction and speed
2Loss of information
If various information contents are displayed, then the information content is sufficient, but the display becomes cumbersome and increases operator burden
Solution Approach 1:
The patent merges multiple information parameters (movement direction and movement speed) into a single integrated visual element (the directed line segment), allowing the operator to perceive both pieces of information simultaneously without processing separate display elements
Solution Approach 2:
By using the geometric dimensions of the line segment (length for speed, orientation for direction), the patent encodes multiple parameters in a single visual object, reducing cognitive load while providing comprehensive information
3Ease of operation
If the remote operation terminal provides comprehensive information display, then operability improves, but the display complexity increases
Solution Approach 1:
The patent uses parameter encoding where the directed line segment's geometric parameters (length, orientation) directly represent physical parameters (speed, direction), providing comprehensive operational information through a simple visual metaphor that does not increase display complexity

AI summary
The present invention provides a remote control terminal which achieves both easy visibility and easy control by indicating the movement direction and the movement speed of a work device as a directed segment according to the operation direction and the operation amount of an operation tool. The present invention provides a remote control terminal which remotely controls a crane device of a crane, the remote control terminal being provided with: a terminal-side communication unit; a suspended load movement operation tool; a terminal-side display device; and a terminal-side control device. The terminal-side control device calculates a vector which represents the movement direction and the movement speed of the crane device according to the operation direction and the operation amount of the suspended load movement operation tool, and the terminal-side control device displays an image in which the directed segment representing the vector is superimposed on the image captured by the camera.
