Innovation Solution
A method and system for joint control of vehicle doors and platform doors, where a vehicle-mounted device sends open-or-close-vehicle-doors commands to a first ground device, which determines validity and generates corresponding open-or-close-platform-doors commands, ensuring accurate platform door control by monitoring timing and validity, and feeding back state information to improve reliability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the platform doors system autonomously controls opening and closing based on microwave carrier waves, then compatibility with various train types and operation schemes is achieved, but the requirements for determination accuracy of the platform doors system increase significantly
Solution Approach 1:
The patent introduces a vehicle-mounted device as an intermediary component that assists the ground device in determining train operation states and door side information. This intermediary device collects and transmits train state information, reducing the burden on the ground-based platform doors system and improving determination accuracy without sacrificing compatibility with various train types and operation schemes.
2Adaptability or versatility
If the platform doors system determines train operation state and door side information autonomously, then the control solution satisfies various train operation schemes, but erroneous judgement may occur affecting operation order and efficiency
Solution Approach 1:
The patent implements a feedback mechanism where the vehicle-mounted device continuously provides train state information to the ground device, and the system monitors and verifies determination results. This feedback loop reduces erroneous judgments by cross-checking information from multiple sources and providing real-time corrections, thereby improving reliability while maintaining versatility across different operation schemes.
Solution Approach 2:
The system performs preliminary determination of train operation states and door side information before actual door control actions are executed. The vehicle-mounted device prepares and transmits necessary information in advance, allowing the ground device to verify and validate data before making critical control decisions, thus preventing erroneous operations while supporting various train types.
3Productivity
If the platform doors system autonomously controls door operations, then operation efficiency is improved, but high requirements for determination accuracy increase system complexity
Solution Approach 1:
The patent divides the autonomous control function into separate modules: the vehicle-mounted device handles train state monitoring and information collection, while the ground device performs determination and control decision-making. This segmentation distributes system complexity across multiple components, allowing each to specialize in specific functions, thereby maintaining high operation efficiency while managing overall system complexity through functional decomposition.

AI summary
Disclosed is a method for joint control of vehicle doors and platform doors applied to a high-speed railway. The method includes: sending, by a vehicle-mounted device, an open-or-close-vehicle-doors command to a first ground device; determining, by the first ground device, a validity of the open-or-close-vehicle-doors command and performing a processing operation depending on the determination; converting, by a second ground device, the open-or-close-platform-doors command received from the first ground device into a platform-doors-relay-driving command recognizable by a platform doors system and sending the platform-doors-relay-driving command to the platform doors system; performing, by the platform doors system, an open-or-close-platform-doors action; capturing, by the second ground device, platform-doors-relay-state information, converting the platform-doors-relay-state information into first platform doors state information and sending the first platform doors state information to the first ground device; and converting, by the first ground device, the first platform doors state information into second platform doors state information and determining whether to return the second platform doors state information to the vehicle-mounted device. Thus, the stability and reliability of the vehicle doors/platform doors joint control system are improved, improving the efficiency of operation.
