Rail Vehicle Diagnostic Software for Modular Maintenance Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods and systems for monitoring and diagnosing rail vehicle components lack flexibility and efficiency, particularly in adapting software for condition-based maintenance without disrupting operation or compromising safety.
Innovation Solution
A modular evaluation software structure that allows dynamic addition, deletion, or modification of software modules via a control center, enabling continuous adaptation and integration of new functions during operation, with communication between onboard units and a control center for predictive maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the evaluation software uses a fixed structure, then system stability is maintained, but adaptability to new maintenance requirements is reduced
Solution Approach 1:
The evaluation software is divided into independent, interchangeable modules that can be individually added, removed, or updated. Each module handles specific maintenance evaluation tasks, allowing the system to adapt to new requirements by simply adding or modifying individual modules rather than redesigning the entire software structure.
Solution Approach 2:
The software architecture transitions from a static, fixed structure to a dynamic, configurable structure where modules can be loaded and unloaded at runtime. This enables the system to dynamically adapt its functionality based on changing maintenance requirements while maintaining a stable core framework.
2Adaptability or versatility
If software modules are added or modified during operation, then maintenance flexibility is improved, but system reliability may be compromised
Solution Approach 1:
Software modules are pre-validated and prepared before being deployed to the rail vehicle. The control center verifies module integrity and compatibility before transmission, ensuring that only reliable, tested modules are installed. This preliminary validation maintains system reliability while enabling flexible updates during operation.
Solution Approach 2:
The control center acts as an intermediary between module developers and the onboard evaluation system. It manages the secure transmission, validation, and installation of software modules, ensuring that updates are performed reliably without compromising operational safety or system stability.
3Measurement precision
If comprehensive monitoring of all components is implemented, then diagnostic accuracy is improved, but data processing complexity increases
Solution Approach 1:
The monitoring system divides comprehensive component monitoring into specialized modules, each responsible for specific component types or diagnostic functions. This segmentation allows the system to maintain high diagnostic accuracy across all components while managing data processing complexity through modular organization and specialized handling of different data streams.

AI summary
The invention relates to a method for monitoring and diagnosing components (2, 4) of a rail vehicle, as a singular rail vehicle or as part of a rail vehicle train consisting of a plurality of rail vehicles, with regard to the necessary repair or maintenance, as appropriate, of at least one component (2, 4), in which at least one measuring device (6, 8) captures at least one measurement variable, which is relevant to an assessment of a necessary repair or maintenance, as appropriate, of the component (2, 4), an evaluation of the captured measurement variable with regard to a repair or maintenance of the affected component (2, 4), which is necessary immediately or in the future as appropriate, is carried out by an evaluation software implemented in an evaluation device (10, 12) arranged on board the rail vehicle or rail vehicle train, and, in the event that the evaluation device (10, 12) deems that it is necessary for a repair or maintenance of the corresponding component (2, 4) to be carried out immediately or in the future, a message (14, 16) in this respect is generated by the evaluation device (10, 12) and transmitted to a control center (28), which is located outside the rail vehicle (1) or outside the rail vehicle train. The invention is characterized by supplementation, extension, modification or adaptation of the evaluation software implemented in the evaluation device (10, 12) by means of instructions, data and/or software modules sent from the control center (28) to the evaluation device (10, 12).
