Train Signaling Device Modular National Module Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing train signaling devices require new approval and additional costs when a national signaling module is added after the device has been installed on a train, which is inconvenient and costly for freight trains crossing multiple countries.
Innovation Solution
A signaling device with software that detects and activates national signaling modules without the need for new approval, by using groups of instructions for module detection, activation, and deactivation, allowing the train to operate with added modules without re-certification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a national signaling module is added to the device after it has been put into service on board a train, then the adaptability of the signaling system is improved, but a new approval of the entire device becomes necessary, increasing costs and complexity
Solution Approach 1:
The patent segments the signaling device into a fixed approved core (ERTMS system) and modular national signaling modules. The ERTMS system remains unchanged and approved, while national modules can be added or removed independently. This segmentation allows individual modules to be modified without requiring re-approval of the entire system, resolving the contradiction between adaptability and approval complexity.
Solution Approach 2:
The patent creates a universal interface and control architecture that can work with multiple different national signaling modules through a single ERTMS system. The configuration module provides multi-functionality by supporting various national modules through standardized interfaces, allowing the same core system to serve multiple purposes across different countries without requiring separate approvals for each configuration.
2Reliability
If the number of national signaling modules is fixed at the time of installation and approval, then the reliability of the approved configuration is maintained, but the ease of operation for adding modules is reduced
Solution Approach 1:
The patent performs preliminary actions by pre-configuring the ERTMS system with the capability to recognize and manage multiple national signaling modules through standardized interfaces. The configuration module is pre-programmed with knowledge of various national modules, allowing them to be added later without requiring system re-approval. This preliminary preparation maintains reliability while enabling easy operation.
Solution Approach 2:
The configuration module acts as an intermediary between the approved ERTMS system and the national signaling modules. It provides a buffer layer that translates between the standardized ERTMS interface and various national module protocols, allowing modules to be added or removed without affecting the core approved system. This intermediary maintains system reliability while facilitating easy module addition and removal.

AI summary
The device (10) has control signal outputting terminals (11, 13) connected to a train. A protection and electrical connection unit (17) electrically connects first national signaling modules (18, 20, 22) to European Rail Traffic Management System (ERTMS) type on-board signaling system (14). Each module is characteristic of a country, and processes national data addressed to the train by a current signaling network, when it is activated by groups of instructions (32-35) of software (16). The number of groups of instructions is strictly higher than the number of the modules. The protection and electrical connection unit has an empty place (23) to receive and electrically connect a second national signaling module. An independent claim is also included for a method for forming and validating, on-board a train, a signaling device.
