Train Door Control via Segmented Identifier Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current train door control systems lack flexibility and operational efficiency, particularly when multiple trains park at the same platform, as they rely on unified control instructions that do not account for differing arrival and departure times, leading to inefficiencies and safety concerns.
Innovation Solution
A train door control method and system that acquires unique identifiers for each train and uses a logic control circuit board and signal system to control the opening and closing of doors at different time points, ensuring safety and improving operational efficiency by allowing separate control of each train's doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If unified control instructions are used to control doors of multiple trains, then the control system is simple, but the operational efficiency and flexibility deteriorate when multiple trains park at the same platform
Solution Approach 1:
The patent segments the door control system by introducing train-specific identifiers and separate control logic for each train. Instead of a unified control instruction for all trains, the system now acquires first and second train identifiers to distinguish between different trains, enabling independent door control for each train based on its specific arrival and departure times.
2Device complexity
If unified control instructions are used for all trains, then the control method is simple, but the flexibility deteriorates when trains have different arrival and departure times
Solution Approach 1:
The control method is segmented by train identifier, allowing different control strategies for different trains. The system acquires train identifiers and applies specific control logic for each train's door operations, enabling flexibility to handle varying arrival and departure times while maintaining manageable complexity through structured identification and control sequences.
Solution Approach 2:
The control system becomes dynamic by adapting door control timing based on individual train characteristics. The system adjusts door opening and closing times for different trains (first train vs. second train) according to their specific schedules, transforming a static unified control approach into a dynamic train-specific control approach.
3Device complexity
If doors of multiple trains are controlled simultaneously, then the control process is simple, but safety deteriorates due to potential conflicts between trains
Solution Approach 1:
The control process is segmented by introducing train identifier-based control sequences. The system acquires first and second train identifiers to distinguish between trains, then controls door operations for each train separately based on their specific timing requirements, eliminating safety conflicts that would arise from simultaneous unified control while maintaining a structured and manageable control process.
Solution Approach 2:
The system performs preliminary identification of trains by acquiring train identifiers before executing door control operations. This preliminary action of identifying and distinguishing between different trains enables the subsequent control process to safely manage door operations for multiple trains by preparing the control sequence in advance based on train-specific information.

AI summary
A train door control method and system are provided. The train door control method includes: acquiring a first train identifier and a second train identifier when multiple trains park in a platform at the same time, a door of a first train to which the first train identifier belongs being to be opened at a current time point, and a second train to which the second train identifier belongs being a train arranged behind the first train, which enters the platform and parks in the platform; and controlling the opening and closing of the door of the first train and a door of the second train at different time points respectively according to the first train identifier and the second train identifier.
