• Analogue Data Replay (e.g. Points and Track

Circuits)

• E-mail Alerts

• Logger Status & Configuration

• Interlocking & Level Crossing Graphical Replay

• Bookmarks

• Reporting & Data Export

Triggered Capture Replay

• Central storage of capture traces sent from

data loggers (MIMOSA XML)

inspection and comparison

• Tagging of traces (normal, anomaly, baseline,

fault)

• User commenting of traces

• Filtering of traces by direction and tag

• See appendix 1

Logger Status & Configuration

• Live status of all configured loggers

• Live log of messages received from loggers

• Mapping of logger inputs to channels within

the system

Analogue Channel (e.g. Track Circuit) Replay

• Graphical replay of analogue data

• Overlay multiple inputs on a graph to inspect

correlations

• Save graph configurations for repeat use

• See appendix 2

Alerts

• Create e-mail alerts based on a given condition

template

• Suppression period configuration to reduce

repeat alert notifications

• Alert on capture trace values (area under curve,

average current, peak current, trace time)

• Alert on analogue level thresholds

• Alert on interlocking/track-side digital events

o Train travelling over speed

o Signal passed at danger (SPAD)

o Relay state change

o Track flick

o Points loss of detection during

passage of train

o Signal reversion

• Live status of all configured alerts, organised by

location

• Audit/replay of triggered alert notifications

(including suppressed)

• Disable e-mail notifications during known

maintenance periods

Interlocking & Level Crossing Replay

• User-editable, drag and drop track map

designer

• Playback of event data represented as

graphical track map

• Concise listing of all monitored relay events

• Logic analyser to confirm sequencing and

timing of events

• Create bookmarks to quickly navigate back to

an incident/fault

• See appendix 3 and 4

Bookmarks

• Create bookmarks of incidents to share with

other users or to re-visit

• Add additional user comments / references to

bookmarks

• Immediately navigate to the playback screen

for the time of the incident

CENTRIX Condition Monitoring

Where is Centrix currently used?

Points Monitoring

• Centrix is being used by a Class I railroad in the

United States.

• The customer is presently evaluating the

benefits of Point Condition Monitoring at 12

sites, prior to a major roll-out.

• Centrix can interface with the customers EMC

Smarts system using SNMP traps.

• During the trial phase, no maintainer

intervention has been conducted on the

monitored point ends.

• This has enabled MPEC to gather quality data

from the point machines, and from the

maintainer about point failures.

Track Circuit Monitoring

• MPEC have strong working relations with

Bombardier Transportation. Centrix has been

used to monitor digital EbiTrack 200, 300 and

400 series receivers and transmitters for a

number of years.

• This includes monitoring of EbiTrack 200 track

circuits in Mackay, Queensland for three years.

• Centrix was used in the UK as a vital tool to aid

with the network acceptance of the EbiTrack

400 system. Centrix has been used to perform

verification and validation of EbiTrack

operation at a number of diverse sites across

the UK.

Interlocking/LX Replay

Centrix is used extensively in the UK for graphical replay

of interlocking and level crossing data

• Free-wired and geographical relay

interlocking’s

• Panel Multiplexer Systems

• Solid State Interlocking’s

• All varieties of Level Crossings

What tools are used to develop the software?

• Application development, build and debugging

using IntelliJ IDEA 12/13

• Build and dependency management provided

by Apache Maven

• Continuous integration of development using

Atlassian Bamboo

• Agile feature/bug backlog management,

planning, work-in-progress and reporting using

Atlassian JIRA

What is the underlying database?

• Percona Server (MySQL replacement) is used for

the core database. Percona is an open-source

MySQL alternative that provides the enterprise-

grade stability and scalability of MySQL, with

the additional performance tuning from

Percona

• Hazelcast is used as an in-memory data store

for caching objects and efficient processing of

alert conditions

How often is the software upgraded/new

releases available?

• Development is carried out in 2-week iterations

at which point a releasable product is available

• Production releases are usually deployed once

a month, however may be as often as 2-weeks
