Remote Operation Calibration Matching for Faster Work Machine Startup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation systems for work machines, such as hydraulic excavators, face inefficiencies due to the need for frequent recalibration of correction values when the actual machine operation mechanism or remote operation mechanism changes, leading to delays in starting remote operations.
Innovation Solution
A remote operation support system that includes a first support processing element to determine if the remote operation factor corresponds to the actual machine operation factor, and a second support processing element to execute processing to match these factors only when they do not correspond, thereby improving operational efficiency.

Engineering Contradiction Analysis
1Measurement precision
If correction value registration processing is executed every time communication between remote operation apparatus and work machine is established, then matching accuracy between remote operation mechanism and actual machine operation mechanism is ensured, but remote operation start time is delayed and operation efficiency is reduced
Solution Approach 1:
The system performs correction value registration processing in advance by storing correction values in advance in advance storage units (124a, 124b) before actual remote operation begins. When communication is established, the system checks whether correction values are already registered rather than performing full registration processing, thereby ensuring matching accuracy while reducing startup delay.
2Productivity
If correction value registration processing is skipped to improve remote operation start efficiency, then operation efficiency is improved, but matching accuracy between remote operation mechanism and actual machine operation mechanism cannot be ensured
Solution Approach 1:
The system includes a determination unit (121) that checks whether correction values are already registered by comparing current machine identification information and mechanism identification information with stored information. This feedback mechanism ensures that registration processing is performed only when necessary (when information changes), maintaining matching accuracy while improving operational efficiency by avoiding redundant processing.
3Reliability
If full correction value registration processing is performed every time, then reliability of remote operation control is maintained, but processing complexity and time consumption increase
Solution Approach 1:
The system segments the correction value registration processing into two distinct paths: a determination process that checks whether registration is necessary (determination unit 121), and an execution process that performs registration only when needed (registration unit 122). This segmentation maintains reliability by ensuring registration occurs when machine or mechanism changes are detected, while reducing processing complexity and time by avoiding full registration during unchanged operations.

AI summary
Provided is a system or the like which can achieve improvement in remote operation efficiency of a work machine by improving an efficiency of calibration processing. A determination result of whether a remote operation factor corresponds to an actual machine operation factor is recognized by a first support processing element 121. “The remote operation factor” is a factor defining an operation setting of a remote operation mechanism 211 included in a remote operation apparatus 20. “The actual machine operation factor” is a factor defining an operation setting of an actual machine operation mechanism 411 included in a work machine 40. Processing of making the actual machine operation factor correspond to the remote operation factor is executed by a second support processing element 122 on a requirement that the determination result is negative.
