Creating or editing an asset

To create or edit an EBITtrack 400 asset begin by navigating to the asset list, using the menu on the top left of the Centrix front-end.

Use the create asset control on the top left to define a new asset, or search for a pre-existing asset by name, and edit using the pencil control on the right of the list entry.

If you’re creating a new asset, you’ll be asked to select the asset type, in this case an EBITrack 400 receiver.

You will then be presented with the asset create/edit display.

At the top, you will need to enter an asset name, and confirm the default asset parameters are acceptable. The asset parameters are as follows:

Asset Parameters

These asset parameters can be tweaked to adjust the behaviour of the occupation labelling system and the health score calculation.

The channel fields shown above are used to map Centrix channels to datalogger channels. The names of the datalogger channels and Centrix channels should generally match

As shown above, asset-to-asset relations can be defined, for example linking adjacent track sections, points and crossings. The latitude and longitude of the asset can also be defined. At a future date, these parameters will be used to evaluate the impact of weather/environment on the asset and associate the performance of adjacent/joined assets.

Once all the fields are filled in or changed, the save changes control at the bottom of the page must be clicked to save changes.

Creating or editing alarms

Alarms for EBITrack 400s are based on an asset health score. The asset health score is a percentage, with 100% assigned to assets with no apparent faults, 0% assigned to assets with many anomalous occupations indicating a fault, and percentages in between reflecting to proportion of good to anomalous occupations. The health score can be viewed on the asset status page (shown in the section below) and is treated as a synthetic data channel on the asset in Centrix. Alarms can be raised when the asset health score is low.

Alarms for EBITrack 400 assets can be created and updated either in bulk using the alarm wizard, or individually. In both cases, begin by navigating to the alarm management page using the menu on the top left of the Centrix front-end.

To use the alarm wizard to create/update multiple alarms, use the create multiple alarms control in the top left. To create an individual alarm use the create new alarm control on the top left. To edit an existing alarm individually, find the alarm in the main list on the right, highlight it, and use the edit control.

Using the alarm wizard

After clicking the create multiple alarms control you will be presented with the following menu, which allows you to pick the alarm type to create. For EBITrack 400s, select the Track Circuit alarm option.

After selecting Track Circuit alarms you will be presented with the following page.

First highlight the box labelled Automatic.

Next, select the Alarm Sensitivity level on the bottom left. A high sensitivity alarm will provide earlier warnings about developing faults but at the cost of false alarms, whereas a low sensitivity will provide less timely notice of faults but with minimal false alarms.

Next, select the assets you want to create alarms for using the Select Assets control. The list can be filtered by site or group if needed.

The training data date range selectors do not need to be adjusted for EBITrack 400 alarms, as the relevant “learned” alarm parameters are updated automatically.

Once all the above items have been completed, use the Next control to generate/update the alarms.

You will then be presented with the alarm generation status page.

After a few moments, each asset will have an alarm generated for it. A green checkmark will appear next to each alarm in the list once the alarm calibration process is complete.

At the top of the page, you can edit the following items:

If you click on the alarms in the list, you can assign additional alarm labels to individual alarms if needed and edit the Advanced Configuration options shown below.

These advanced options should normally be left at the default shown here, however if you wish to edit them, refer to the description of these parameters in the Creating and editing assets section above.

Creating and editing individual alarms

For more control over alarm creation, alarms can be created and calibrated individually, using the Create new alarm or Edit control on the alarm management page. When these controls are clicked you will be presented with the edit alarm page.

Here the following items can be specified

Once all of these items have been completed, use the Save Alarm control to save or update the alarm.

Using alarm labels

Alarm labels can be considered as a mailing list, typically used where a team of people are monitoring a group of assets. When an alarm label is created, a list of emails can be added to it, so that when an alarm with this label is raised all the recipients will receive an email. Alarm labels can be created and edited by navigating to the Alarm Labels page via the Centrix menu in the top left of the front-end.

Viewing the current and historical status of alarms

The current and historical status of alarms can be monitored in real-time by navigating to the Alarm Status page via the Centrix menu in the top left of the Centrix front-end.

By default, this page lists all active alarms. Alarms which have just been raised have a red exclamation icon next to them, and alarms which have been raised in the past but not yet acknowledged have a blue icon. The list of alarms can be filtered by type, site, and severity using the controls on the left of the page, with an option to include alarms which are not active.

Clicking on an alarm raise report will open a small menu below it (as illustrated above). From here you can navigate to the asset status page, the alarm raise history, or alarm raise report using the relevant control. Once the alarm has been investigated and dealt with, clicking the Clear Alarm control will remove the alarm raise from this page.

Viewing the current and historical status of an asset

The current and historical status of an asset can be investigated and viewed by clicking on the asset in the asset list page.

When the asset view page is first opened, the asset playback tab is shown by default.

For EBITrack 400 devices, the most recent track occupation is shown. Using the time and navigation control above the chart, occupations can be flicked through by date, alarm raise, event, or tag. In the image above we can see that this occupation has been given two tags by Centrix: a high current and unstable current tag, indicating that this occupation is anomalous. When occupations receive tags like this, the health score for the associated asset drops.

Beneath the occupation chart, the most recent value recorded on each asset channel is displayed. These values will be updated as the time and navigation control at the top of the page is moved.

Configuration parameters associated with the asset are listed in the asset details table at the bottom.

The next tab on the asset page is the alarm tab. Here all the alarms associated with this asset are shown in the alarms table. If there are other alarm types available for this asset which have not yet been created, they are listed in the missed asset alarms table. By clicking the checkmark next to the missing alarm entries and using the Generate Selected Alarms control, these alarms can be automatically generated.

Finally, by clicking on the health tab, a time-series chart showing the historical health score is shown, allowing the user to review the health of the asset over time.

Generating reports

The reporting tool in Centrix can be accessed via the Centrix menu in the top left of the Centrix front-end.

Several types of report can be generated to summarise historical data in Centrix. For EBITrack 400 assets, the following reports may be useful.
