Creating a New Report

Image Modified

To create a new report, fill in the input values (explained below) and click the Create Report button to generate a new report.

The report takes the following input parameters;

Parameter	Description	Example
Site Name	The level crossing site to generate a report for, select from the drop-down list.	My LX
Report Title	The title of this specific report, this will populate the "Line" field in the Excel report.	Up Fast

From Date

Time Range	The date range to run the report

from

over. Select 'custom' to manually set a start and end date. To set these values, click the

field to display the

'start date' and 'end date' boxes to bring up a date picker.

04/08/2014To Date

The date to run the report to, this must be after the "from date", click the field to display the date picker.

08/08/2014Sequence

The start date must be before the end date.

Channels

The unique sequence of events to extract the warning time.
This must contain at least entries, one for the start event and one for the end event. For SIN/137 this should be the functions that represent the strike-in and arrival.
Additional events may be added to guarantee a match on the sequence (specifically necessary for bi-directional lines).

To add to the sequence, select the channel from the list

and select whether you want to detect when the function changes to UP or DN. Then

, then click the + button.

When you've added

the state changes

a channel to the sequence, you should select a State (either up or down).

When you've added all the required channels, set the Start and End

event

events using the radio buttons in the sequence list. The report will calculate the time between the Start and End event, this allows you to add sequence proving events before and after the start/end events without them affecting the sequence timing.

Warning

There is a known limitation, any channels that are used in the sequence must have their states fully represented from the strike-in event through to the arrival event. This is especially important when using something such as a treadle as the strike-in, for example the following sequence will fail to generate any timings:

535b QNPR,DN,S

538 T1PR,DN,A

By the time arrival event is fired, the train has already passed the treadle which caused the 535b QNPR channel to change state to UP. This extra event in between the strike-in and arrive causes the report generator to miss the sequence as the strike-in channel is essentially "disarmed" before the arrive event is encountered. To resolve this issue, simply ensure that all channels used in the level crossing sequence (535 QNPR and 538 T1PR in this example) have their states fully represented:

535b QNPR,DN,S

535b QNPR,UP,-

538 T1PR,DN,A

The Event Replay feature in Centrixcan help identifying the correct level crossing sequence.

1 TR,DN,S
A (DWL) R,UP,-
2 TR,DN,A


Design Time	The minimum warning time (in seconds) from LX design	30
Route, Line Name, ELR, Crossing Name, Crossing Type, Direction.	These fields should be entered and will be automatically entered into the NR/SIN/137 report upon download
File name	The file name to be given to the generated report download. .xls will be added automatically so there is no need to enter it.

Note

title	Dates

When selecting a custom date range, the time will be automatically set to midnight (00:00) on the start day and 23:59 on the end day.

Once you have specified the report parameters and clicked the Create Report button the page will refresh and , you should be redirected back to the list. There, there should be a new report entry at the bottom of the Reports section. Notice that the Status column currently indicates that the report is PENDING. Reports are stored in a queue on the server which is processed every 5 seconds, hit the Refresh button after a few seconds and repeat until the status of the report has changed.Image Removedtop of the list, with a loading spinner and a yellow indicator.

When the report has finished processing you should see READY in the Status column, the report is now ready to be viewed.Image Removedthe indicator should change to green.

You will be taken to another screen, towards the top of on the page you'll see data categorised into the time bins (20 to 100 and >100).

Towards the bottom of the page you can a pair of graphs displaying the current distribution of time sequences for each bin. Each bin represents a particular sequence length in seconds, and the count is the number of sequences that have this length. These bins are automatically selected to fully contain all the available data. If you wish to reduce the number of bins this can be achieved by editing the minimum and maximum bin values below the graphs and pressing the View button.

The data used to generate these graphs is displayed below in the Sequence Data table.
