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.

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……

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.

In service trains

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.

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?
