Dear Readers and Friends,
The 6th edition of FRAUSCHER-NEWS is naturally dominated
by InnoTrans 2010.
The leading rail technology event that takes place every two ye-
ars is for many companies an important milestone to announce
innovations or new developments.
This also applies to us, as Frauscher Sensortechnik GmbH will
introduce at InnoTrans 2010 a number of new products and
further developments to any interested visitor of the trade fair
and to our valued customers.
The core of our new developments is our next generation
axle counting system: The Advanced Counter. This sys-
tem, which will not necessarily replace the current ACS2000,
does, offer a large number of new options within its range of
application, such as the integration with electronic signalling
boxes. With a minimum of components and the possibility, for
instance, to communicate safely with super ordinate applica-
tions using Ethernet interfaces, we have laid the foundation for
a new promising generation of systems. By using our proven
wheel sensor technology we have achieved a clear reduction in
capital expenditure and life cycle cost compared with conven-
tional systems.
As one of the world‘s leading manufacturers of highly availa-
ble wheel sensors our Company has a special interest in the
standardization of admissible electromagnetic interferences
at the vehicle/general infrastructure interface. Work regarding
CENELEC standard EN 50238-3 is now showing significant
progress and our Company is collaborating with the EMC re-
search group of DB within the „Sensor System Workgroup“.
Yet, we also strive to pioneer a vehicle / wheel sensor inter-
face that is transparent, measurable and rateable. Hence we
disclosed last year the magnetic interference limitations of our
sensors (see FRAUSCHER-NEWS 04/2009). However, we want
to take it a step further.
We want to provide railway operators and rolling stock manu-
facturers with a measuring device that allows comprehensib-
le standard rating of the electromagnetic interferences along
the rail caused by the different vehicles types. To that effect
we have developed a system in cooperation with ÖBB (Aus-
trian Railways), which goes by the name of Magnetic Noise
Receiver MNR. Accordingly, the newly developed HF and LF
measuring antennas are rail-mounted simply by using rail claws
much like our wheel sensors. The measurement data recorded
are then read and evaluated by a PXI system adapted by Frau-
scher.
But this does not exhaust the number of all the new presenta-
tions planned by our Company.
Presentations include wheel sensor RSR181, a further deve-
lopment of the RSR180 with plug-in cable, the FDS diagnostics
systems as well as a detailed update on the state of the art of
wheelset detection on grooved rails.
InnoTrans is a very international trade fair. We are expecting
many of our international customers and partners at our stand
and all relevant contacts from Frauscher‘s branch offices in
the UK, China, Poland and Austria will be present. We are loo-
king forward to exchanging opinions about the latest products,
technological trends and correct system strategy. To this effect
please take note of two important events:
Our customer evening, Tuesday September 21, 2010, at 6
p.m., presenting Frauscher as a true Austrian company offering
Austrian gastronomic specialities, and our lecture on Thursday
September 23, 2010, between 3 and 4 p.m. in the Speaker‘s
Corner about „Technological challenges for inductive wheel
detection and axle counting technology of the future“.

FRAUSCHER-NEWS – Edition 06 | September 2010
The Frauscher Advanced Counter System FAC is the new axle
counter system generation by Frauscher Sensortechnik GmbH.
The necessary development was started back in 2006. The de-
velopment target was an axle counting system with less com-
ponents and open communication interfaces. This target has
been achieved.
The main features of the system are as follows:
� integration of wheel sensor signal evaluation, safe axle
counting and output of the safe clear/occupied status
on a single board
� communication between all components using a CAN bus
� possibility to communicate with super ordinate systems
(signalling box, level crossing, etc.) or adjacent systems
using serial interfaces
� possibility for user-friendly queries of status data of the
equipment using an optional touch screen
� possibility for decentralised placement of boards along the rail
The central board, the Advanced Evaluation Board AEB (see
figure 3) of the Advanced Counter, not only evaluates the RSR
wheel sensor data, but also carries out axle counting and pro-
vides the clear/occupied indication, which can be output using
either a serial protocol or relay interfaces.
Additionally, the FAC system provides the possibility to input di-
gital data that are independent from axle counting, using the in-
put/output/extention boards IO-EXB (see figure 4) and to output
them at other IO-EXB’s (e. g. transmission of block arguments).
Furthermore, the Frauscher Advanced Counter System FAC can
also be integrated into the Frauscher Diagnostics System FDS

Functional design
The FAC system comprises of at least the following boards:
� Power supply board PSC (see figure 2), which processes
the externally provided voltage supply and protects the
system
� Evaluation boards AEB (see figure 3), one per wheel sensor
and which can be configured for section counting
� Communication interface board COM to link geographi-
cally dispersed track sections of the FAC as well as for
safe serial communication or the adequate number of
input/output/extention boards IO-EXB (see figure 4) for the
necessary relay interfaces
All boards of the FAC system are mounted in 19“ board racks.
The evaluation boards AEB of the Advanced Counter commu-
nicate via CAN bus.
The communication interface board COM, equally connected
to the CAN bus, provides an Ethernet interface, which in turn
provides a safe clear/occupied indication for further proces-
sing. Alternatively, the clear/occupied indication can also be
output by the input/output/extention boards IO-EXB connected
to the evaluation boards AEB.
In addition, the communication interface board COM allows
connection of the FDS diagnostics system by Frauscher to the
Advanced Counter System FAC. The FDS system allows log-
ging and evaluation of relevant data. The user interface for the
FDS is a web browser.
Configuration of the track sections can be carried out electively
using DIP switches on the configuration board CO-EXB or a
configuration file.
Over longer distances the communication interface boards
COM communicate via Ethernet. Ethernet connections can be
established using e. g. LWL or DSL modems. It is also possible
to use existing communications networks, provided they com-
ply with class 5 or less as set forth in EN 50159-2.
The power supply board PSC provides the necessary voltage
for the CAN bus and protects the interface boards (up to 19
AEB evaluation boards) of the Advanced Counter against over-
voltages.

Applications
Due to the functional modularity and flexible scalability using
the Ethernet interface, the Frauscher Advanced Counter FAC
system can be configured for all conceivable applications.
From small central systems with direct relay outputs and touch
screen to complex systems in clusters distributed locally along
the track and networked via Ethernet; anything is possible. As
system complexity increases, savings in space, energy and ca-
pital expenditure also increase significantly compared with con-
ventional axle counting systems.
Integrated in efficient electronic signalling boxes the FAC sys-
tem offers all its options with minimal hardware, secure sus-
tainable communication and maximum flexibility. Customised
interfaces are developed individually in cooperation with the
respective system vendor and based on the interface environ-
ment specified.
The development by Frauscher of communication and interface
standards specified by the different railway operators is either in
progress or already implemented.

Optimal support for Frauscher customers and projects has always been a focal point of the Company‘s business philosophy. This
objective has been achieved for many years now either through cooperation with partners in different countries or by establishment
of branch offices for sales and services.
Frauscher Branch Offices
The Polish branch office Frauscher Polska Sp. z o.o. with head office in Ka-
towice was founded back in 1998. Over the years the company succeeded
in establishing itself in the Polish market, wherefore, naturally, many projects
now feature axle counting technology by Frauscher.
To mention but a few reference projects:
� E139 line
� E20 line
� CMK line

The idea for the development of the Magnetic Noise Receiver
MNR is actually a few years old and came about when Frau-
scher Sensortechnology became an active member of the DB
workshop dedicated to the electromagnetic radiation of vehic-
les within the frequency range of sensor systems. The „Sensor
systems workgroup“ is an offspring of that workshop. The cor-
rect measuring process for recording and evaluation of magne-
tic interference fields was the topic of many discussions.
Since there is still no measuring device able to record all three
axes of the interference fields in a single measurement cycle,
Frauscher has used its experience in the field of sensor techno-
logy in order to develop a measuring device that complies with
the following requirements:
� easy mounting and erection of the measuring device
� fast commissioning affording minimal time at rail
� resistance against current stress loads at the rail
� coverage of the complete frequency range of 10 kHz to
1,3 MHz
� admissible deviation < 1,5 dB
� 3D detection of measuring fields in a single test run
� automatic start and stop of measurements
� recording of traversing speed and provision of a normal
time stamp
� online evaluation of measurement data in compliance with
EN 50238-3 (2009) and comparison with maximum admis-
sible threshold values
� online evaluation of measurement data using FFT analysis
Product requirements were reviewed in cooperation with Aust-
rian Railways (ÖBB). Shortly after, the first prototype was ready
to be tested under laboratory conditions. However, this proved
Magnetic Noise Receiver MNR
to be difficult, because first it was necessary to generate a noise
spectrum that had to be recorded using a Helmholtz coil. After
adequate adaptations of the MNR the first field test together
with ÖBB was soon under way.
So as to achieve optimal linearity the required frequency range
had to be captured by two antenna systems, operating simulta-
neously if required. Recordings in the lower frequency range are
made by the MNR-LF probe. The higher frequencies are recor-
ded by the MNR-HF probe and cover all three axis (X-Y-Z).
A MNR probe (see figure 8) comprises, besides the recording
coils, all electronics necessary to linearise frequency response.
This allows measurement results with amplitude deviations of
< 1,5 dB.
The preamplifier equally integrated into the MNR with
downstream anti-aliasing filter allows the transmission of the
measurement data through shielded cables and over longer di-
stances (approx. 25 m). This procedure allows the MNR recor-
der to be operated away from the probe, i. e. outside the danger
zone of the rail.
The MNR recorder (see figure 8) is a highly precise analogue re-
cording device. The collected analogue data are evaluated on-
line by a processor. Calculation results and analogue data can
be saved to the hard disk of the mobile processor. Operation
and online evaluation do not require any other external devices,
such as a laptop (see figure 7).
EN 50238 stipulates that especially those frequency ranges re-
served for sensors must be viewed in detail and assessed in
compliance with the diagrams forming part of EN 50238. Based

on the reference diagram the evaluation can be immediately
interpreted as measurement result (see figure 9).
However, knowing and displaying the residual spectrum is also
of interest to infrastructure operators and vehicle manufactur-
ers as rail vehicle licensing conditions also include interference
spectra outside the preferred sensor frequencies. For this pur-
pose the evaluation algorithm of the MNR recorder was expan-
ded with a FFT analysis (see figure 10). This affords a conti-
nuous display of the entire emission spectrum.
Thus, the MNR probe with a MNR recorder is also suitable for
lasting deployment at the rail (e. g. at check points) for the per-
manent monitoring of passing rolling stock.
The measuring device is monitored by means of a Helmholtz
coil.

Summary of advantages:
� 3D recording of the interference field in a single run
� one traversing cycle is enough to record the entire frequency range
� compatibility measurements according to EN 50238-3 with just one measuring device
� possibility to display the entire interference spectrum
� evaluation as per EN 50238 by comparison with the diagrams on site

Business development in China
CRCEF, a company of the CRSC Group has signed a coopera-
tion agreement with Frauscher Sensortechnik GmbH regarding
the integration of Frauscher wheel detection components into
the new axle counting system of the JZ.GD series. The system
is to allow deployment for all applications (subway, main line
and high speed lines) and is based on the world-wide proven
wheel sensor and evaluation technology by Frauscher. This co-
operation agreement continues the long-standing partnership
of the two companies and is an important element in the busi-
ness development of Frauscher Group in China.

14001 and OHSAS 18001 this evaluation by DB AG is an im-
portant commendation for our Quality Management System.
Frauscher-Short-Notes
New board production line launched
May 2010 saw the start of manufacture of the board production in its new premises (see figure 11). The new conditions increase
production capabilities and optimise the flow of materials during the production process. Another advantage of the new production
area is the expansion and improvement of the switching cabinet production (see figure 12). The pillar jib crane mounted in that area
supports both production and packing/delivery of the axle counting systems mounted into the switching cabinets.
