Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current train control systems face challenges in achieving interoperability between different suppliers and railroads, particularly when shared tracks are involved, due to variations in technology and design solutions.
Innovation Solution
A generic virtual train control system is introduced, implemented in a cloud computing environment, which indirectly connects physical train control system elements to virtual train control application platforms. This approach simplifies system implementation and facilitates interoperability by focusing on interfaces between physical and virtual elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical train control elements interact directly in a railroad operating environment, then system functionality is achieved, but interoperability between different suppliers becomes difficult
Solution Approach 1:
The patent introduces a virtual train control system as an intermediary layer between physical train control elements and railroad operations. This virtual system standardizes interactions through defined interfaces, enabling different physical systems from various suppliers to interoperate seamlessly without direct complex integration.
Solution Approach 2:
The patent creates virtual copies of physical train control elements that operate in a standardized virtual environment. These virtual representations maintain the functional behavior of physical elements while providing uniform interfaces for interoperability across different suppliers and railroad operations.
2Adaptability or versatility
If train control systems are customized to meet specific railroad requirements, then functional requirements are satisfied, but system complexity increases
Solution Approach 1:
The patent segments the train control system into standardized virtual components that can be independently configured. This modular virtual architecture allows specific railroad requirements to be met through configuration of individual virtual elements rather than customizing the entire system, reducing overall complexity.
Solution Approach 2:
The virtual train control system provides a universal platform that can be configured to meet different railroad-specific requirements through standard interfaces. This multi-functional virtual environment allows the same core system to adapt to various operational needs without increasing fundamental system complexity.
3Adaptability or versatility
If different technologies and design solutions are employed by various suppliers, then technological diversity is achieved, but interoperability on shared tracks becomes challenging
Solution Approach 1:
The virtual train control system serves as a universal intermediary that translates and standardizes different physical technologies from various suppliers into a common virtual interface language. This enables diverse technological solutions to interoperate reliably on shared tracks through the standardized virtual layer.
