DataMapMaking sense of rail infrastructure asset data

DataMapTM
The data storage, display and analysis tool designed to manage the large volumes of infrastructure data collected by rail monitoring vehicles
DataMapTM supports a move to ‘predict and prevent’ maintenance It helps make the best use of available data and turns it into useful information that can be easily understood. DataMap™ provides a sound foundation for ‘predict and prevent’ maintenance regimes and helps control maintenance costs.
Best use of available dataDataMap™ can take data from any number of different sources, recorded on different vehicles and dates, and spatially align the data together on a geographical map of the rail network. For example, a combination of track geometry, structure gauging and video can be used to provide the user with detailed information pertaining to the track asset and the surrounding infrastructure at a specific location on the railway network.
Our methodology delivers significant benefitsDataMap™ utilises a model based methodology. This locates data with greater consistency run-on-run and in turn, offers significant benefits for analysis and maintenance management.
capabilitiesSoftware
More effective maintenance DataMap™ supports more effective maintenance by readily identifying clusters of repeat faults. Once under control, repeat fault clusters can be managed on a proactive basis by predicting when they will become safety threatening in the future and directing maintenance before this happens in a cost effective manner.
The same is true of monitoring statistical quality parameters which are recorded across the same section of track with a location consistency across runs that allows small trends to become discernable over time.
Users can also perform “what if” analysis for cost effective modelling of maintenance regimes.
Versatile system supports many requirementsThe versatility of the system services a huge range of requirements; from the engineer who wants to upload the latest data and pull off the fault details for immediate, cost-effective, targeted, action with the minimum of effort; to the engineer who wants to examine data in detail across a range of data types to hunt for correlations to obtain a better understanding of the infrastructure. Quality indices provide ideal management tools for monitoring and demonstrating improvements to the track.
With vehicle captured video, it is even possible to perform a track walk in the comfort of the office with all aspects of the recorded data synchronised with the video frames, allowing stop, start, forward and reverse play-back functionality. In this context, DataMap™ can reduce track-walking costs dramatically, by providing the engineer with all measured aspects of track, synchronised with video, in the safety of the office – ideal for monitoring heavily trafficked sections of the network.

Technical InformationThe heart of DataMap™ is a link node model definition of the railway. Each link is a unique section of track that links two nodes. Any data which can be mapped to the link node model of the network is available at a given location, providing the universal view of all data spatially synchronised against the model definition. This includes video frames, profiles of running rails or structures, ballast profiles, geometry, corrugation, overhead line, ultrasonics data etc.
Data viewing is not restricted to paths taken by recording vehicles. A user can define any contiguous path of interest on the model and DataMap™ will then stitch together the latest available data for that path, link by link. The system will, if required, use data from different vehicles and different recording dates to present the most recent composite view. Alternatively, selected data can be superimposed in any combination of date order.
The system also allows reporting by areas or regions rather than by specific contiguous paths, providing a wealth of statistical parameters that define the quality of the geometric area as a whole.
DataMap™ utilises Microsoft SQL Database and supports laptop versions with full functionality, but limited database storage capability using SQL Express (Microsoft license free) for track walking support or for the remote user.
Security and region definitions ensure that users only see the data that they are allowed to view and that they only perform the functions they are privileged to access.
DataMap™ consists of the following main entities:
Tabular Based Reporting
DataMap™ will generate tables of exceedence or statistics data and the content of these tables can be sorted in a multitude of different ways, for example; order of severity, order as encountered along the path etc., serious safety breaches only etc. The resultant table can then be printed directly or exported. Excel exports are directly available and Excel can be used to format up data in any manner required with the use of macros etc.
The Upload Facilities
The Upload process allows data recorded to be registered against the Link Node Model and then loaded into the DataMap™ data repository spatially synchronised against the model and thereby with every other data set stored.
Enhanced Visualisation
The visualisation tool is composed of a chart area (the main area for viewing data), and a number of additional windows giving further information, as required by the operator. During operation, the operator can modify both the chart and the additional windows.The operator has the ability to configure the following elements:
• Theregionoftherailnetworktobedisplayed• Thetypesofdatatobedisplayed• Howeachtypeofdataistobedisplayed
The map of the network is used to ensure consistent run-on-run registration of data, which is vital to ensure accurate trending of data over time, as well as for the production of well targeted fault reports.
The Link Node Model
DataMap™ is intimately bound to a link node model of the railway network. This is a geometric representation of the railway which provides the sub-metre consistency in reporting location run-on-run across time.
The model has a time dimension embedded into it which ensures that if track is changed and the model is updated, data remains bound to the model description at the time that the data was captured.
The model can be of a very simple nature (horizontal, linear representation of paths without interconnectivity) to a full geometric representation encompassing interconnectivity between paths, thereby allowing any contiguous path of interest to be mapped.
The Data Repository
A repository for data, either held within the DataMap™ database itself, or within files that reside in a file repository intimately linked to the database content through stored metadata.
The Viewing Facilities
A range of facilities based on plug-in architecture that allow the myriad data types to be displayed on screen, spatially synchronised.
The Processing Facilities
Facilities that process data and present the results to the user, such as raw data smoothing, “as is” design determination, statistics calculations based on user defined measurement section lengths etc.
