Railway Route Detection via Light Panel Image Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current railway route data from light control panels is not accessible in an automated manner, limiting the ability to efficiently manage maintenance, accident prevention, and operator training, as these panels do not provide digital or analog data for subsequent use.
Innovation Solution
A method and device that analyze images of light control panels to determine railway routes automatically, without physical or electrical interaction, by comparing current and previous images to identify route segments, allowing for dynamic tracking and storage of route data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If light control panels are used to display railway journeys, then visual information is provided, but digital or analog data for automated processing is not available
Solution Approach 1:
The patent uses image capture devices (cameras) to create visual copies of the light control panel displays. These images are then processed through image recognition algorithms to extract route information, effectively copying data from an optical display format into a digital format that can be automatedly processed and stored.
2Productivity
If automated methods are implemented to access route data, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent replaces manual observation and documentation methods with automated image capture and processing systems. Cameras and image recognition software automatically capture and analyze the light control panel displays, eliminating the need for manual data transcription and significantly improving productivity while managing complexity through software-based solutions.
3Ease of operation
If image analysis methods are used to determine routes, then ease of operation is improved, but measurement precision may be affected
Solution Approach 1:
The patent implements feedback mechanisms where the system captures images of the light control panel, processes them through image recognition, and then validates the extracted route information against known route patterns and databases. This feedback loop allows the system to correct errors and improve accuracy while maintaining ease of operation through automated processing.
