Frauscher Tracking Solutions FTS

The best of both worlds: The combination of Frauscher Acoustic Sensing FAS and axle counters or wheel detection systems creates new possibilities for railways.

A range of tests with DAS revealed that limitations of existing approaches regarding their use on railways can be overcome through intensive research. Frauscher has installed its own expert team to take full advantage of potential that this technology can provide. All members of that working group thus had to bring fundamental knowledge regarding DAS as well as about the needs and standards of the railway industry.

FTS-FAS: Frauscher Acoustic Sensing – a railway specific DAS

A railway specific DAS based solution has now been developed in close cooperation with interested railway operators who gave valuable inputs regarding some important criteria. These affected, for example, the system resolution that is needed to carry out various applications as well as transmission and storage of data. In a subsequent step, the research group developed some prototype-algorithms to enable detection and classification of specific events.

The outcome of this process, Frauscher Acoustic Sensing (FAS), is now available for some basic applications. These include train tracking in nonsafety relevant areas, monitoring of infrastructure components, for instance by detecting wheel flats, rail breaks or people and activities, such as digging on and near the track.

Even the initial pilot installations have revealed a range of additional application areas. Now we plan to make further revisions to hardware and software, to evaluate further potentials within these specific fields.

Integration with detection systems: FTS-FAS+

In an early combination, FAS is used together with proven wheel detection systems and wheel sensors: overlaying data from both approaches increases the possibilities of applying such information significantly. Trains can be assigned to tracks and their length can be determined more exactly. Furthermore, detected events and asset conditions, such as wheel flats, can be localised accurately. Thus an integrated solution with wheel detection systems enables the use of FAS on multi-track lines, where several rails are connected by numerous switching points.

FAS provides additional information for modern axle counters: FTS-FAdC+

The most advanced combination consists of FAS and a modern axle counter, such as the Frauscher Advanced Counter FAdC. In this configuration, the FAS provides valuable data to support complex and safety-relevant applications, given that the axle counter operates on a CENELEC SIL 4 level.

Using FTS-FAdC+, the axle counter can be used as a failsafe system for track vacancy detection, while data input from FAS, such as dynamic train location or estimated time of arrival (ETA), can be added.

Human Machine Interface HMI

True to the motto “track more with less” we have also developed a specific Human Machine Interface (HMI) for making access to and handling of all generated data as simple as possible: the FAS Display Unit. This provides clearly arranged delivery of all information as well as accurate classification of tracked events as a basis for planning and implementing appropriate activities.

Furthermore, information can also be provided to mobile devices through text messages or even drones that can be sent to appropriate locations according to precise GPS data. Additionally, interfacing with IT networks is enabled.
Whichever option is chosen, FTS allows for immediate response, either as a standalone or as a combined solution.
