Locomotive Auto-Driving Mode Switching with State Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current railway trains lack reliable and safe methods for switching between manual and automatic operation modes, leading to potential loss of control or safety issues due to improper mode switching.
Innovation Solution
A method and apparatus for switching the operation mode of a train, which involves determining if state information from the automatic train operation device and control devices indicate that the automatic operation mode is allowed, prompting activation if conditions are met, sending activation instructions, and switching to the automatic mode upon receiving acknowledgment from all control devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver switches operation mode based on experience without standardized procedures, then the switching process is simple and fast, but the reliability and safety of mode switching deteriorates due to potential loss of control or improper switching
Solution Approach 1:
The system performs preliminary detection of switching conditions before executing mode switching. The automatic train operation device detects whether switching conditions are met (including checking if the train is in a safe state for mode transition) before allowing the driver to switch modes, preventing improper switching and ensuring safety before the actual mode change occurs.
Solution Approach 2:
The system provides feedback to the driver regarding the status of switching conditions. The automatic train operation device detects and communicates whether the conditions for mode switching are satisfied, giving the driver informed feedback before mode transition, thereby improving reliability while maintaining operational control.
2Reliability
If comprehensive condition checking is performed before mode switching, then the safety and reliability improve, but the switching time and operational efficiency worsen
Solution Approach 1:
The system continuously monitors and pre-evaluates switching conditions in the background before a mode switch is requested. By having the automatic train operation device already detect and assess whether switching conditions are met prior to the driver's switching action, the system prepares safety verification in advance, reducing actual switching time while maintaining comprehensive safety checks.
3Productivity
If the automatic operation mode is activated without verifying control device states, then the productivity increases, but the train may be out of control due to loss of suitable operation commands
Solution Approach 1:
Before activating automatic operation mode, the automatic train operation device performs preliminary detection to determine whether switching conditions are met, including verifying that control devices are in appropriate states. This preliminary check ensures that the train will remain controllable and have suitable operation commands available before transitioning to automatic mode.
Solution Approach 2:
The system provides feedback on the status of control devices and switching conditions before allowing automatic mode activation. The automatic train operation device communicates whether conditions for safe mode switching are satisfied, ensuring that productivity gains from automatic operation do not compromise control reliability.

AI summary
A locomotive driving mode switching method, an apparatus, and a computer readable storage medium. Said method comprises: determining whether state information of control apparatuses and self-state information satisfy an automatic driving mode; and when all the state information and self-state information satisfy the automatic driving mode, displaying prompt information of activating the automatic driving mode; upon reception of an automatic driving activation instruction in conformity to a safety rule, sending the automatic driving activation instruction to the control apparatuses, and upon reception of response messages for automatic driving activation confirmation fed back by the control apparatuses, adjusting a self-driving mode to the automatic driving mode, thereby completing switching of a locomotive from a manual driving mode to the automatic driving mode. A locomotive can switch to the automatic driving mode only when all apparatuses satisfy the condition of entering an automatic driving mode, improving the reliability and safety of switching a locomotive driving mode.
