Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current control systems for reconfigurable multi-unit vehicles, such as trains, face challenges in efficiently and safely managing composition changes due to their reliance on fixed Input/Output configurations and complex synchronization algorithms, leading to slow performance and increased complexity, which can result in safety risks if not informed of configuration updates.
Innovation Solution
A method that autonomously determines and updates the composition of a multi-unit vehicle using a device for determining composition, generating composition data, and dynamically securing connections between computers and Input/Output modules, ensuring consistency and safety through a security module that prioritizes connections and verifies consistency cyclically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed Input/Output configuration is used in the control system, then the system structure is simple and reliable, but the system cannot adapt to composition changes of the multi-unit vehicle
Solution Approach 1:
The patent applies dynamics by making the Input/Output configuration dynamic rather than fixed. The control system automatically reconfigures its Input/Output connections based on the current composition of the multi-unit vehicle, allowing adaptation to changing configurations while maintaining operational reliability through automated management of connections.
Solution Approach 2:
The control system performs self-service by autonomously determining the vehicle composition and automatically managing its own Input/Output configuration. The system self-updates its connection map without external intervention, reducing the need for manual reconfiguration and maintaining simplicity despite adaptability.
2Adaptability or versatility
If complex synchronization algorithms are used to manage composition changes, then the system can handle reconfiguration, but the performance becomes slow and complexity increases
Solution Approach 1:
The system performs preliminary action by pre-establishing a complete map of possible Input/Output connections and preparing the control system to instantly activate appropriate connections when composition changes occur. This pre-preparation eliminates the need for complex real-time synchronization algorithms, improving response speed.
Solution Approach 2:
The patent extracts the composition determination function from the control system's core processing, separating it into an independent determination device. This extraction allows the control system to quickly receive composition information and directly update its configuration without complex synchronization, improving productivity.
3Reliability
If the control system does not update composition data, then the system remains stable and simple, but safety risks increase when units are uncoupled or coupled
Solution Approach 1:
The system implements feedback by continuously monitoring the actual composition of the multi-unit vehicle and comparing it with the stored composition data. When changes occur (units uncoupled or coupled), the system receives feedback about the new configuration and automatically updates its data, maintaining safety without complex manual intervention.
Solution Approach 2:
The control system performs self-service by autonomously detecting composition changes and automatically updating its own composition data. The system self-corrects any discrepancies between expected and actual configuration, maintaining reliability while simplifying the update mechanism through automated self-management.
