Train Operation Diagram Adjustment for Emergency Section Closures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing train operation plans are difficult to adjust efficiently during emergencies such as sudden section or station equipment failures, leading to inefficiencies in dispatching multiple trains across multiple stations.
Innovation Solution
An automatic adjustment method for a train operation diagram that involves drawing a closing symbol to determine a closed section, registering resource occupancy, and performing station track, arrival/departure time, and section operation time adjustments based on registered resources to generate an adjustment result, which is then applied to the operation diagram.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual operation is used to adjust train operation plans during emergencies, then flexibility in handling complex situations is maintained, but dispatching efficiency and adjustment speed deteriorate
Solution Approach 1:
The system performs automatic adjustment of train operation diagrams by itself without requiring manual intervention. The adjustment module automatically generates adjustment schemes based on emergency information, resource occupancy data, and predefined adjustment conditions, thereby maintaining flexibility while significantly improving dispatching efficiency
Solution Approach 2:
The patent replaces manual mechanical operations with an automated computer-based system. The adjustment module uses algorithms to automatically calculate and generate train operation adjustments, substituting human manual work with electronic computation to achieve both efficiency and adaptability
2Reliability
If manual adjustment of multiple trains across multiple stations is performed during short-time emergencies, then comprehensive control is maintained, but adjustment speed and response time deteriorate
Solution Approach 1:
The adjustment process is segmented into distinct automated modules: information acquisition, resource occupancy registration, adjustment scheme generation, and diagram adjustment. This segmentation allows each module to process specific tasks efficiently while maintaining comprehensive control over the entire adjustment process
Solution Approach 2:
The system implements feedback mechanisms where resource occupancy information is continuously registered and used to validate adjustment schemes. The adjustment module receives feedback from resource occupancy data to automatically refine and optimize adjustment plans, ensuring comprehensive control while accelerating response time
3Productivity
If automatic adjustment system is implemented for train operation diagrams, then dispatching efficiency and response time are improved, but system complexity increases
Solution Approach 1:
The adjustment module is designed as a universal system that can handle multiple types of emergencies (section failures, station equipment failures, train failures) and perform multiple adjustment functions (train tracking, resource allocation, timetable revision) through a single integrated platform, thereby improving efficiency without proportionally increasing complexity
Solution Approach 2:
The system introduces an intermediary adjustment module that acts as a mediator between emergency information input and operation diagram output. This intermediary layer processes and coordinates multiple adjustment parameters automatically, managing system complexity while maintaining high dispatching efficiency
4Measurement precision
If resource occupancy registration is performed based on closing symbols and failed trains, then accurate adjustment planning is achieved, but data processing complexity increases
Solution Approach 1:
The system performs preliminary registration of resource occupancy information based on closing symbols and failed train data before actual adjustment is needed. This pre-processing of data establishes an accurate baseline for adjustment planning, improving measurement precision while managing data processing complexity through advance preparation

AI summary
An automatic adjustment method includes: drawing a closing symbol in case of emergency during train operation, and determining a closed section for adjusting a train operation diagram and adjustment conditions for the operation diagram by the closing symbol; obtaining a train set to be adjusted based on the adjustment conditions for the operation diagram; obtaining a train with failure in the closed section, and registering resource occupancy based on the closing symbol and the train with failure in the closed section to generate a resource occupancy list; performing station track adjustment and calculation, arrival and departure time adjustment and calculation, and section operation time adjustment and calculation on each train in the train set to be adjusted based on the resource occupancy in the resource occupancy list, and obtaining a corresponding adjustment result; and applying the adjustment result of each train to a corresponding planned line in the operation diagram.
