Rail Station Dispatch System Modular Plan Parsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Centralized Traffic Control (CTC) system for high-speed railways is inadequate in meeting the transport commanding needs, particularly in terms of timely and effective delivery of station plans and ensuring secure operation with disaster tolerance.
Innovation Solution
A station transport dispatching method and system that includes a station plan management module which sends requests to a storage query module to load and update station plans and train graph stage plans, enabling automatic parsing and timely delivery of operation routes, and incorporating main/standby switchover processing for secure operation and improved disaster tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the existing CTC system is used for train dispatching, then basic train operation control is achieved, but the system cannot meet the transport commanding needs for timely and effective delivery of station plans
Solution Approach 1:
The system is divided into distinct functional modules: station plan management module, storage query module, plan processing module, route processing module, and train arrival departure control module. Each module handles specific tasks independently, enabling timely processing of station plans while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The station plan management module proactively sends requests to load station plans and train graph stage plans from the database at startup and before processing. This preliminary loading ensures that necessary data is ready when needed, enabling timely delivery of station plans without waiting for ad-hoc queries during critical operations.
2Reliability
If the CTC system operates without main/standby switchover mechanism, then system operation is simpler, but disaster tolerance and secure operation are compromised
Solution Approach 1:
The system implements a main/standby mechanism where a standby station plan management module is prepared in advance to take over if the main module fails. This cushioning approach ensures continuous operation and disaster tolerance without requiring complex real-time redundancy management during normal operation.
Solution Approach 2:
The standby module is created as a copy of the main module, maintaining the same functional capabilities. This copying approach provides disaster tolerance by having an identical backup ready to take over, while keeping the system structure relatively simple through replication rather than complex redundant architecture.
3Ease of operation
If manual processing of station plans is used, then system operation is straightforward, but the convenience of dispatching and automatic parsing of operation routes is reduced
Solution Approach 1:
The plan processing module automatically parses station plans into operation routes without requiring manual intervention. The system serves itself by autonomously extracting route information, processing it through the route processing module, and delivering it to the train arrival departure control module, thereby improving dispatching convenience through automation.
Solution Approach 2:
The system implements automatic feedback loops where the station plan management module sends requests to load plans, the plan processing module parses them into routes, and the results are automatically delivered to control modules. This automated feedback mechanism enhances dispatching convenience by eliminating manual processing steps while maintaining high extent of automation.
