Train Turn-Back Control Using Single On-Board Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current train turn-back control methods require communication links with two sets of vehicle on-board-devices, which affects the turn-back success rate and efficiency, and increases hardware consumption.
Innovation Solution
A method and system that enables train turn-back control using a single set of vehicle on-board-device, where the current state information is determined and reset to obtain new state information for performing turn-back control, thereby reducing the need for multiple communication links and hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two sets of vehicle on-board-devices establish communication links with the zone controller for turn-back control, then the turn-back control can be realized, but the turn-back success rate and efficiency are reduced
Solution Approach 1:
The patent extracts and removes the zone controller from the turn-back control process. Instead of requiring communication between vehicle on-board-devices and the zone controller, the system enables direct peer-to-peer communication between the leading vehicle's on-board-device and the non-leading vehicle's on-board-device, eliminating the intermediary and improving both success rate and efficiency
Solution Approach 2:
The vehicle on-board-devices perform turn-back control autonomously through direct communication with each other. The leading vehicle's on-board-device sends a turn-back instruction to the non-leading vehicle's on-board-device, which then executes the turn-back without requiring zone controller intervention, enabling the system to serve itself
2Reliability
If two sets of vehicle on-board-devices and communication links are used for turn-back control, then the turn-back function can be achieved, but the hardware consumption is increased
Solution Approach 1:
The patent merges the turn-back control function into the existing vehicle on-board-devices. The same on-board-device that controls normal train operation is also used for turn-back control through direct communication, eliminating the need for separate dedicated hardware or additional communication infrastructure
Solution Approach 2:
The vehicle on-board-device is designed to perform multiple functions: it controls both normal train operation and turn-back operations. The on-board-device can communicate with both the zone controller for normal operations and directly with other on-board-devices for turn-back, making it a universal component that reduces overall hardware requirements

AI summary
The present disclosure provides a train turn-back control method, device and system. The method includes: determining first state information of a train when confirming that a turn-back instruction is received; directly resetting the first state information to obtain second state information; and performing turn-back control on the train according to the second state information. The present disclosure can realize turn-back control on the train based on a single set of vehicle on-board-device, thereby improving the turn-back success rate and turn-back efficiency of the train, and reducing the hardware consumption.
