Machine Video Timeline Interface for Fast Abnormality Review
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional monitoring data processing devices require significant time and effort to locate specific moments in videos when abnormalities or changes occur, making it difficult to quickly identify and view these events.
Innovation Solution
A monitoring data processing device that includes a data recording unit for acquiring and storing video data and chronological data of an industrial machine, an image display unit for generating a chronological image indicating changes along a time axis, and a video display unit that allows users to easily select and view specific moments by moving a slider on the image, distinguishing between operation and stop states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional monitoring data processing devices store video data without chronological state information, then storage space is saved, but time and effort increase significantly when trying to locate specific moments of abnormalities or changes
Solution Approach 1:
The system performs preliminary action by generating a chronological image that visually represents the chronological data before the user needs to locate any specific moment. This chronological image is created in advance and displays the operational state, stop state, and physical quantity changes over time, allowing users to quickly identify and navigate to abnormal moments without manually searching through video data.
Solution Approach 2:
The chronological image serves as an intermediary between the raw chronological data and the video data. Instead of directly searching through video files or raw data logs, users interact with the visual chronological image that mediates the search process, making it easier to locate specific moments by visually identifying abnormalities in the displayed operational states and physical quantity changes.
2Measurement precision
If the system displays detailed chronological data for every moment, then measurement precision is improved, but information overload makes it difficult to identify key events
Solution Approach 1:
The chronological image applies local quality by displaying different visual characteristics for different operational states and abnormal conditions. Specific regions of the chronological image represent different time periods or state transitions, allowing users to focus on locally relevant information while maintaining the ability to see the overall timeline, thus preventing information overload while preserving detection precision.
Data Source
AI summary
A monitoring data processing device includes: a data recording unit to acquire and store video data of an industrial machine captured by a camera, and chronological data of a state or a physical quantity of the machine or a manufactured workpiece; an image display unit to generate and display, on a monitor, a chronological image visually indicating a change in the chronological data and to display a slider to indicate a position on the chronological image along the time axis; a console to move the slider along the time axis; and a video display unit to display the video of the machine corresponding to a position of the slider. The chronological data includes first chronological data that enables distinguishing between an operation state and a stop state of the machine, and the chronological image based on the first chronological data distinguishably indicates the operation state or the stop state.
