Dynamic Train Marshalling Control via Carriage Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current urban rail transit systems face inefficiencies due to fixed train marshalling, which limits flexibility in adjusting carriage quantities to meet varying transportation demands throughout the day, resulting in suboptimal operating efficiency.
Innovation Solution
A train dispatching control method and system that dynamically reconfigures train compositions by determining target carriages based on real-time positioning information and controlling their movement between designated parking lines to form and unform trains, enabling flexible deployment to match transportation capacity requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed train marshalling is adopted, then train structure stability is maintained, but flexibility in adjusting carriage quantities to meet varying transportation demands is reduced
Solution Approach 1:
The train is divided into independent carriages that can be individually controlled and positioned. Each carriage has its own positioning information that can be independently determined, allowing the train to be segmented into different configurations (marshalled or unmarshalled) based on transportation demands without requiring complex manual reconfiguration operations.
Solution Approach 2:
The train marshalling configuration is made dynamic rather than fixed. The system can automatically transition between different marshalling states (connected or unconnected) based on real-time positioning information and transportation requirements, enabling flexible adjustment of carriage quantities while maintaining operational simplicity through automated control.
2Productivity
If manual train marshalling operations are performed, then train reconfiguration is achieved, but operating efficiency and labor costs are reduced
Solution Approach 1:
The train marshalling system performs self-service through automated determination of target carriages based on positioning information. The system automatically identifies which carriages should be connected or disconnected and controls their movement without requiring manual intervention, thereby improving marshalling efficiency while maintaining appropriate levels of automation control.
Solution Approach 2:
The system uses real-time positioning information feedback from each carriage to automatically determine the target carriages for marshalling operations. This feedback mechanism enables the system to make intelligent decisions about train configuration adjustments, improving operational efficiency while reducing the need for manual monitoring and control.
3Measurement precision
If real-time carriage positioning information is used to determine target carriages, then marshalling accuracy is improved, but system complexity increases
Solution Approach 1:
The positioning system serves multiple functions: it tracks carriage locations, determines target carriages for marshalling, monitors train configuration status, and supports both marshalling and unmarshalling operations. This multi-functionality reduces the need for separate specialized systems, thereby improving positioning accuracy without proportionally increasing overall system complexity.

AI summary
A train dispatching control method includes obtaining a train marshalling instruction, determining target carriages corresponding to a marshalling quantity based on carriage positioning information corresponding to to-be-dispatched carriages parked on to-be-dispatched parking lines, and controlling all the target carriages to drive from the to-be-dispatched parking lines to a marshalling dispatch parking line, to form a target train. The train marshalling instruction includes the marshalling quantity.
