Train On-board Display Synchronization Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional on-board information display systems for trains cannot combine multiple display devices to form a single synchronized screen, leading to ineffective information display.
Innovation Solution
An on-board information display device with a controller that determines whether to synchronize or non-synchronize display screens based on the type of information to be displayed, using a display-execution-processing determination unit and display data generation unit to generate appropriate display data for the display units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display devices are used to display different information on different screens, then information distribution flexibility is improved, but the ability to combine displays into a single synchronized screen deteriorates
Solution Approach 1:
The system dynamically switches between independent display mode and synchronized display mode based on the type of information to be displayed. The display execution processing determination unit determines whether to synchronize displays, and the display data generation unit generates appropriate display data, enabling the system to adapt its operation mode in real-time rather than being fixed in one configuration
Solution Approach 2:
The on-board information display device is designed to perform multiple functions: it can display information independently on each display device, or combine multiple display devices into a single synchronized screen. This multi-functionality allows the same hardware system to serve different information distribution needs without requiring separate systems
2Device complexity
If display screens are displayed independently on multiple display units, then device simplicity is improved, but information display effectiveness deteriorates
Solution Approach 1:
The system dynamically adjusts its display configuration based on information type. For information requiring unified presentation, it synchronizes displays to form a single screen, enhancing display effectiveness. For information suited to distributed presentation, it uses independent displays. This dynamic adaptation resolves the contradiction between simplicity and effectiveness

AI summary
An on-board information display device can effectively display information by synchronizing a plurality of display units in accordance with information to be provided. The on-board information display device controls a plurality of display units, and includes an on-board information display controller including: a display-execution-processing determination unit that outputs a display-execution-processing determination result indicating whether parts or all of display screens to be displayed on the plurality of display units are to be synchronized, in accordance with on-board information to be displayed on the plurality of display units; and a display data generation unit that receives the display-execution-processing determination result and generates display data to allow the display screens to be displayed on the plurality of display units, in synchronization or without synchronization in accordance with the display-execution-processing determination result.
