Teach Pendant Screen Capture for Robot Restore Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backup systems for robot controllers do not capture all data, such as temporary information and secure data, leading to incomplete restoration and difficulty in verifying the restored state matches the original state.
Innovation Solution
A robot system with a teach pendant that captures and saves image data files of information screens with timestamps, allowing comparison of different states to verify restoration accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backup files are created to restore robot controller state, then restoration capability is improved, but verification of restoration accuracy becomes difficult due to the enormous number of screens
Solution Approach 1:
The patent creates visual copies (screenshots) of all control screens and saves them as image files with timestamps. These image copies serve as restorable records that can be compared with current screens to verify restoration accuracy, eliminating the need to manually check each screen after restoration
Solution Approach 2:
The patent performs preliminary screening and saving of all control screens before restoration occurs. By capturing and storing screen images in advance with timestamp metadata, the system prepares verification data beforehand, making post-restoration checking efficient and automated
2Measurement precision
If all control screens are visually checked to verify restoration, then verification accuracy is improved, but time consumption increases due to the enormous number of pages
Solution Approach 1:
Instead of visually inspecting each screen, the patent creates image copies of all screens and stores them with timestamps. Verification is achieved by automatically comparing these stored image copies with current screens, maintaining high accuracy while eliminating manual checking time
Solution Approach 2:
The patent replaces the mechanical process of visual screen checking with an automated image comparison system. By substituting human visual inspection with automated image file comparison based on timestamps, the system achieves the same verification accuracy without time consumption
