On-Board Train Route Request Control for Dynamic Traffic Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In traffic systems that dynamically set paths and train driving intervals without a schedule, the need for independent ground-based hardware and redundant configurations results in high costs and limited ability to accurately control train positions and speeds, leading to inefficient operation.
Innovation Solution
The implementation of an on-board control unit on each train, which communicates with an on-ground control unit to request and manage routes based on real-time data, allowing for accurate control of train operations and potentially eliminating the need for ground-based traffic control hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ground-based traffic control hardware is installed to manage train operations, then train operation control is achieved, but system cost increases and device complexity increases
Solution Approach 1:
The train's own control device requests routes and controls its operation autonomously without requiring ground-based traffic control hardware. The train self-manages its routing decisions based on real-time position and speed data, eliminating the need for external ground control systems.
Solution Approach 2:
The traffic control function is extracted from the ground-based system and transferred to the train's onboard control device. This removes the dependency on ground-based hardware for route management while maintaining operational control capabilities.
2Productivity
If ground-based traffic control device is used, then route management is achieved, but measurement precision of train position and speed deteriorates
Solution Approach 1:
The train's onboard control device independently measures its own position and speed using its sensors and systems, providing accurate real-time data without relying on ground-based measurement infrastructure. This self-measurement capability ensures high precision while maintaining route management functionality.
3Reliability
If redundant configuration is adopted for traffic control device, then system reliability is improved, but device complexity and cost increase
Solution Approach 1:
The train's onboard control device provides inherent reliability through autonomous operation and real-time monitoring capabilities. The system self-manages its control functions without requiring redundant ground-based hardware configurations, achieving reliability through智能化 control rather than hardware redundancy.

AI summary
The present invention provides an operation system which can finely control the operation of a train in response to the operation state of the train at low cost in a traffic system that uses a process of dynamically setting a path and an operation interval. This traffic control system is provided with: on-board control units installed on trains that are traveling, and an on-ground control unit installed on the ground. The on-board control units are installed on a plurality of trains, respectively, the operations of which are managed by the traffic control systems, perform a track demand on the basis of a delivered operation mode, and deliver information on the track demand to the on-ground control unit. The on-ground control unit controls the progress of the train on the basis of the delivered track demand.
