Machine Video Timeline Interface for Fast Abnormal Event 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 efficiently identify and review such events.
Innovation Solution
A monitoring data processing device that includes a data recording unit for acquiring and storing video and chronological data of industrial machines, an image display unit to generate and display chronological images indicating changes along a time axis, and a console to move a slider and select positions on the image for corresponding video playback, allowing easy identification of abnormal or changed states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional video monitoring is used without chronological data integration, then the system structure remains simple, but it takes significant time and effort to locate specific moments when abnormalities or changes occur
Solution Approach 1:
The patent merges video data with chronological data (operation logs, sensor readings, maintenance records) into a unified monitoring system. This integration allows operators to simultaneously view video footage and corresponding operational data, enabling quick identification of abnormal moments by cross-referencing multiple data sources rather than searching through video alone.
Solution Approach 2:
The patent adds a temporal dimension to video monitoring by overlaying chronological data timestamps with video timestamps. This creates a multi-dimensional view where operators can navigate through time using both video playback and chronological data scrolling, making it easier to locate specific abnormal moments by searching through structured operational data rather than raw video content.
2Ease of operation
If chronological data is visually displayed with time axis and slider, then identification of special moments becomes easy, but the display interface becomes more complex
Solution Approach 1:
The patent segments the display interface into distinct functional areas: video display region, chronological image region with time axis, slider control region, and data detail region. This segmentation allows each component to perform its specific function clearly, making the overall complex interface manageable and intuitive for operators to navigate and identify special moments efficiently.
Solution Approach 2:
The patent introduces a slider as an intermediary control element that mediates between the chronological image and the video playback. The slider provides a visual and tactile interface for operators to navigate through time, allowing easy selection of specific moments by dragging the slider along the time axis, thereby simplifying the interaction with the complex chronological data.
3Difficulty of detecting and measuring
If the chronological image displays operation state and stop state in distinguishable manner, then abnormal states become easily detectable, but the image processing complexity increases
Solution Approach 1:
The patent uses color changes in the chronological image to represent different operation states (operation state, stop state, abnormal states). Different colors or color intensities indicate different states, allowing operators to quickly detect abnormalities by visual inspection of the color-coded chronological data without complex analysis, thereby simplifying state detection despite the underlying processing complexity.

AI summary
A monitoring data processing device (30A) of the present embodiment includes: a data recording unit (25) configured to store, in a storage unit (17), data of a video of a transfer press machine (50) captured by first and second monitoring cameras (11,12), and chronological data of a state of the transfer press machine (50) during capturing; and an image display unit (26A) configured to generate chronological images (40,46,47) along a time axis from the chronological data for a certain past period and display the chronological images (40,46,47) on a monitor (20). By selecting any position along the time axis on the chronological image (40,46,47) with the console (23), a video corresponding to the selected position is displayed on the monitor (20).
