3. Introduction
 Data transfer has become part of our daily lives,
emails, text messages, social media etc.
 Devices are getting smarter, this means we also
need to get smarter so that we can interface and
analyse the data we receive from them.
 The demand for OCMS has increased the past
few years due to the lines being very busy, new
locomotives being bought and we are unable to
meet the demand from depots, data handling is
one of the major issues that slows down our
performance.
 It is estimated that about 22 exabytes
(23622320128 Gigabytes) of analogue data is
generated. this value is said to double by 2020,
these are devices such as strain gauges, LVTDs,
thermocouples etc.
 With so much data being generated, we need
smarter and efficient ways of dealing with it.
 On average It takes about 1500min ( 5 working
days) to analyse data for the Nactor line.

4. Current data handling by the OCMS
 The OCMS generates an average of
about 1G of data per test depending
on the length of the section being
measured, for this presentation
Natcor line we be used as an
example.
 The data is saved as bin files which is
then converted to PFD files using an
in-house customised program called
OCMS overview.
 The data is then analysed manually
page by page and parameter
exceedances for the contact wire are
extracted.
 This exceedances are then manually
loaded to a program called
mapSource then transferred in to a
GPS device so that visual inspections
can be conducted.
 This process is inefficient ,tiring and
makes people to fell like……

5. SMART Loading of OCMS exceedances and ADD activations into a GPS or smart device
 GPS coordinates are formed by two
components which are latitude and longitude:
 Latitude: North-south with reference to
the equator.
 Longitude: East-west position with
reference to the prime meridian.
 Common GPS coordinate formats:
 DD (decimal degrees) -29.906939 30.975903 or
29.906939S 30.975903E.
 DM (Degree minutes) S29°54.41634S.
030°58.55418E.
 DMS (degrees, minutes, seconds) 29°54'24.98"S
30°58'33.251"E.

GPS device( Garmin )
 R 4 799.00
 If by any chance you are lucky enough to have them both , test, compare
and decide which one is best for your application.

8. RRV
The present/future
 Pre-processing of data.
 Share data with relevant
personnel in real time.
Measuring Vehicles
In service trains

9. Feed back from the coalline
 I've introduced the technology to the coalline maintenance personnel, they managed
to check the ADD activations from the 21Es and managed to locate the defects. They
are very happy with the accuracy and level of efficiency provided by the smart device.

10. Conclusion
 Smarter data management system will enable OHTE faults to be attended almost
immediately, preventing hook-ups which leads to train delays and cancellations.
 Personnel handing the data in just 6 min instead of 1500 min.
 A reliable and available train service will results in:
 Lets make technology our friend, Smart technology and devices can help our
business.
 Technology is like a passenger train and we are like passengers at a station, whether
we jump in or not its still going to pass , so do we jump in or get left behind?
