Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diagnostic systems for rail vehicles struggle to effectively correlate and analyze large amounts of data from multiple assets, leading to potential issues being overlooked and reducing the ability to take preemptive actions due to data overload.
Innovation Solution
A visual diagnostic system that includes a data interface to receive data streams and geo-information from wayside units, determining the geographic location and operational status of each asset, and rendering prognostic information through a user interface for display, utilizing multiple sources for increased accuracy and confidence.

Engineering Contradiction Analysis
1Quantity of substance
If large amounts of data are collected from multiple assets and wayside units, then the potential value for monitoring rail vehicle conditions is improved, but the ability to correlate and analyze the data effectively deteriorates due to data overload
Solution Approach 1:
The system segments the large volume of data by associating each data point with a specific asset identifier and geographic location. The controller divides the overall data stream into asset-specific subsets, making it manageable to analyze and correlate data for each individual asset rather than dealing with the entire data set simultaneously.
Solution Approach 2:
The controller acts as an intermediary between the data interface (receiving raw data) and the user interface (displaying analyzed information). It processes the raw data stream by correlating data with asset identities and geographic locations, transforming unstructured data into meaningful diagnostic information that can be easily interpreted.
2Reliability
If data from multiple assets are aggregated together, then comprehensive monitoring coverage is improved, but the ability to identify specific asset issues deteriorates due to information loss
Solution Approach 1:
The system applies local quality by providing asset-specific diagnostic information within the context of the overall train composition. Each asset receives tailored monitoring and analysis based on its specific data stream, while still maintaining comprehensive coverage of all assets. The visual representation allows operators to drill down into specific asset details as needed.
Solution Approach 2:
The controller segments the aggregated data by asset identifier, ensuring that data from each asset is processed and analyzed separately even though all assets are monitored simultaneously. This segmentation prevents information loss by maintaining distinct data pathways for each asset while achieving comprehensive monitoring coverage.
3Measurement precision
If geographic location data is integrated with asset data, then the precision of asset identification is improved, but the complexity of data processing increases
Solution Approach 1:
The system merges geographic location data with asset operational data in the controller. By combining these data streams and correlating them with asset identifiers, the system achieves precise asset identification without requiring separate processing systems. The merged data is then presented in a unified visual representation that simplifies rather than complicates the overall processing architecture.
Data Source
AI summary
A visual diagnostic system for a rail vehicle having multiple assets is disclosed. The visual diagnostic system may have a data interface configured to receive a data stream from a wayside unit. The data stream includes values of a plurality of parameters measured made by the wayside unit. The data interface may also be configured to receive geo-information and configuration-information. The system further includes a memory device configured to store the data stream and a controller configured to determine, from the geo-information and the configuration-information, a geographic location of each of the multiple assets. The controller is further configured to determine prognostic information associated with an operational status of each of the multiple assets. The controller may further render for display in a user interface a visual representation of the rail vehicle with the prognostic information for each asset of the rail vehicle.
