Remote Operation Connection Hold for Fast Machine Restart
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation systems require a communication connection to be reestablished each time a working machine is restarted after a pause, leading to increased downtime.
Innovation Solution
A remote operation system that includes a remote control element for executing resumption processing and a communication control element to maintain a connected state during machine stop operations, allowing seamless resumption of remote operation without reestablishing communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication connection is reestablished each time the working machine is restarted after a pause, then the remote operation system ensures proper connection state, but the time required to resume remote operation increases
Solution Approach 1:
The communication connection is established in advance and maintained in a ready state before the actual remote operation resumes. The system keeps the communication channel open and authenticated during machine stop operations, so that when the operator wants to resume operation, the connection is already prepared and functional, eliminating the need for reconnection procedures.
Solution Approach 2:
The communication connection between the remote operation apparatus and the working machine is maintained continuously even during machine stop operations. The system prevents the communication session from being fully terminated, keeping data channels open and authentication valid, thereby enabling seamless resumption of remote operation without interruption or reconnection delay.
2Loss of time
If communication connection is maintained continuously during machine stop operations, then the time to resume remote operation is reduced, but the communication system consumes more resources
Solution Approach 1:
The system maintains only the essential communication channels and authentication states during machine stop operations, rather than keeping all communication functions fully active. This partial maintenance approach keeps the connection ready for resumption while minimizing resource consumption by deactivating non-essential communication processes during idle periods.

AI summary
Provided is a remote operation system which can reduce time from when a remote operation is paused to when the remote operation is resumed. When a real machine stop operation is executed by an operator 2 during execution of the remote operation and a specified operation for executing resumption or end of the remote operation is executed by the operator 2 with an on-hand terminal 230, a remote control apparatus 200 of a remote operation system 1 executes resumption processing or end processing of the remote operation, and the remote control apparatus 200 and a real machine control apparatus 400 maintain a communication connected state during a period since the execution of the real machine stop operation until the specified operation is to be executed.
