Train Display Unit Consolidating ATC and CCTV Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional on-board computer systems for trains require multiple dedicated screens and displays for various equipment, leading to space constraints and cluttered cockpits, impairing information clarity.
Innovation Solution
The system allows direct information transmission from electronic control and supervision equipment to display units without passing through the central computer, enabling the display of multiple types of information, including ATC, CCTV, and other equipment data, with automatic selection and presentation of relevant information, reducing the need for multiple screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple dedicated screens and displays are used for various equipment, then information from different equipment can be displayed, but the cockpit becomes cluttered and space constraints are exacerbated
Solution Approach 1:
The patent consolidates multiple dedicated display screens into a single integrated display unit that can show information from various equipment simultaneously. The display unit presents train management information from the central computer along with equipment information from electronic control equipment, ATC equipment, and CCTV equipment on one screen, thereby reducing the number of screens needed and freeing up cockpit space.
Solution Approach 2:
The display unit is designed to perform multiple functions by displaying different types of information from different sources. It can show train management information, equipment status, ATC data, and CCTV feeds, replacing multiple specialized screens with a single multi-functional display that adapts to various information presentation needs.
2Loss of information
If multiple dedicated screens are installed for different equipment, then comprehensive information is provided to the driver, but the cockpit layout becomes complex and costly
Solution Approach 1:
The patent merges multiple information streams from different equipment into a single display unit. The display unit processes and presents train management information from the central computer, equipment information from electronic control equipment, and additional data from ATC and CCTV systems simultaneously on one screen, maintaining information completeness while reducing screen count.
Solution Approach 2:
The display unit serves as a universal display interface that can handle various types of information from multiple sources. It provides a consolidated view of train management, equipment status, automatic train control data, and video surveillance information, eliminating the need for separate dedicated screens for each information type.
3Stability of the object's composition
If information is transmitted through the central computer for all equipment, then centralized control is maintained, but transmission time and network load increase
Solution Approach 1:
The display unit acts as an intermediary that can receive information directly from electronic control equipment without requiring all data to pass through the central computer first. This direct communication path reduces transmission time and network load while the display unit still integrates this information with centralized train management data for comprehensive presentation.
