Remote Operator Handover Control for Stable Working Machine Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When switching remote operation actors of a working machine, the operating state can become unstable due to inappropriate remotely operated actions by the new operator, leading to potential instability in the machine's operation.
Innovation Solution
A remote operation system that includes a working machine with an imaging device and multiple remote operation apparatuses, each equipped with an operation mechanism and image output devices, and a remote operation server that detects specified states of the machine and operators, allowing for seamless transfer of remote operation authority from one apparatus to another based on notifications and processing to ensure stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote operation authority is transferred from one operator to another, then the operator can be changed, but the operating state stability deteriorates due to inappropriate remotely operated actions by the new operator
Solution Approach 1:
The system performs preliminary evaluation of the operating state and operator capability before transferring remote operation authority. The determination unit assesses whether the current operating state is transferable and whether the new operator has the capability to handle it, preventing inappropriate transfers that would compromise stability
Solution Approach 2:
The system continuously monitors the operating state and provides feedback to determine whether transfer is appropriate. The determination unit uses real-time operating state information to decide on transferability, ensuring that authority is only transferred when it will maintain or improve operating state stability
2Adaptability or versatility
If multiple remote operation apparatuses are allowed, then operator flexibility increases, but the complexity of managing remote operation authority increases
Solution Approach 1:
The remote operation server acts as an intermediary between multiple remote operation apparatuses and the working machine. It centralizes the management of remote operation authority, receiving transfer requests, evaluating transferability, and executing authority transfer, thereby simplifying the complexity of managing multiple operators

AI summary
Provided is a system which can avoid instability of an operating state of a working machine, when switching a remote operation actor of the working machine. In a case where a state of one or both of a working machine 40 or a first operator is a specified state when the working machine 40 is remotely operated through a first remote operation apparatus 10, a first notification corresponding to the specified state is transmitted to a remote operation server 30. In the remote operation server 30, a second remote operation apparatus 20 which is appropriate in view of content of the first notification is selected as the remote operation actor of the working machine 40.
