Remote Operation Assistance for Scheduled Work Machine Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation systems for work machines face inefficiencies when switching operations between machines, leading to deteriorated work efficiency due to inadequate preparation for subsequent tasks.
Innovation Solution
A remote operation assistance device that includes a first assistance processing element to determine preparation conditions based on schedule information and transmit control signals to move or position work machines optimally for upcoming tasks, ensuring they are ready for operation when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator performs preparation for the second work machine in parallel with the first work, then the operator can be ready for the second work, but the work efficiency of the first work is deteriorated
Solution Approach 1:
The system automatically performs preparation actions for the second work machine in advance based on schedule information, before the operator needs to switch tasks. This includes automatically moving the work machine to the appropriate position and adjusting its attitude, so that when the operator needs to perform the second work, the machine is already ready without requiring the operator to manually prepare it during the first work
2Speed
If the operator starts the second work without preparation, then the operator can immediately start the second work, but the work efficiency at the start of the second work is deteriorated
Solution Approach 1:
The system executes preliminary preparation actions automatically before the second work starts, including positioning the work machine and adjusting its attitude according to the scheduled work requirements. This ensures that when the operator switches to the second work, the machine is already in the optimal state for that task, eliminating startup delays and efficiency losses
3Reliability
If the work machine is controlled to standby state when a failure occurs, then operator safety is protected, but work continuity is interrupted
Solution Approach 1:
When a failure is detected in the remote operation system, the system automatically controls the work machine to a standby state in advance, preventing the operator from operating a faulty machine. This automatic safety intervention stops work continuity but prioritizes operator safety by preventing operation of compromised equipment

AI summary
A remote operation assistance device configured such that when an operator performs work through remote operation of a work machine, the remote operation assistance device moves the work machine to the position suitable for the work scheduled to be performed by the work machine in advance or changes the attitude of the work machine in advance so as to be suitable for the work. The present invention comprises a first assistance processing element configured to execute a first assistance process that is a process of acquiring schedule information from a database, determining based on the schedule information whether or not a preparation condition is satisfied, and transmitting, when the determination is affirmative, a preparation signal that is a control signal.
