Dynamic Train Tracking Interval Adjustment by Route Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing train equal-interval adjustment methods fail to dynamically adjust train intervals when the number of actual running trains significantly differs from the planned number, leading to uneven distribution and suboptimal passenger experience.
Innovation Solution
A method that determines overlapping and non-overlapping regions based on route information, adjusts train tracking intervals in these regions according to train duration and train count, and dynamically adjusts intervals in real time to ensure even distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed tracking interval is preset, then the equal-interval adjustment method is simple to implement, but it cannot calculate an appropriate train interval when the number of actual running trains significantly differs from the planned number
Solution Approach 1:
The patent transforms the fixed tracking interval into a dynamic one by introducing real-time calculation based on actual train numbers. The system continuously monitors the number of running trains and adjusts the tracking interval accordingly, allowing the interval to change from static to dynamic adaptation to actual operational conditions
Solution Approach 2:
The patent changes the parameter of tracking interval from a fixed preset value to a variable value that is recalculated based on actual train numbers. By making the interval parameter flexible and adaptive rather than rigid, the system can accommodate varying operational conditions without requiring complex manual adjustments
2Extent of automation
If manual calculation is used to adjust train intervals, then the method is simple to implement, but the manual calculation workload of dispatchers increases
Solution Approach 1:
The system performs self-service by automatically calculating and adjusting tracking intervals based on real-time train number data. Instead of requiring human dispatchers to manually perform calculations, the system autonomously monitors train numbers, computes appropriate intervals, and implements adjustments without human intervention
Solution Approach 2:
The patent replaces the mechanical manual calculation process with an automated information processing system. The manual arithmetic operations performed by dispatchers are substituted by computer-based automatic calculation, transforming a human-driven process into an automated technological system
3Reliability
If trains are distributed evenly on the line, then the riding experience of passengers is improved, but the system complexity increases
Solution Approach 1:
The system implements feedback by continuously monitoring the number of running trains and using this information to adjust tracking intervals. This closed-loop mechanism ensures that trains are distributed evenly by real-time feedback from actual operational conditions, automatically optimizing passenger experience through adaptive response
