This report has been specifically designed to meet the requirements of NR/SIN/137.
The report will provide a list of Level Crossing Warning Times for a given sequence and provide statistics to show how many trains fall into which time.
Access the Report
To access this report;
- Login into Centrix
- Click the Reporting tab on the main menu
- Click the Sequence Timing report in the report list
- A new window in your browser should open with the Sequence Timing Report Generator
Create a New Report
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 | The date to run the report from, click the field to display the date picker. | 04/08/2014 |
| To Date | The date to run the report to, this must be after the "from date", click the field to display the date picker. | 08/08/2014 |
| Sequence | The unique sequence of events to extract the warning time. 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 click the + button. When you've added the state changes to the sequence, you should select a Start and End event 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.
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 Centrix can help identifying the correct level crossing sequence. | 1 TR,DN,S |
| Design Time | The minimum warning time (in seconds) from LX design | 30 |
Dates
When selecting a date, the time will be automatically set to midnight (00:00) on the selected day. For example, running a report from Monday to Friday will actually be running the report from the start of Monday until the start of Friday (4 days). To run the report for the whole 5 days, specify the end date as the day afterwards (Saturday in this case).
Once you have specified the report parameters and clicked the Create Report button the page will refresh and there should be a new 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.
When the report has finished processing you should see READY in the Status column, the report is now ready to be viewed.
Download a Report
To download the NR/SIN/137 Excel Spreadsheet for a report, click the Download SIN/137 button next to a report.
You should then be prompted to download the report.
The filename for the report is based on it's parameters and has the following format: sin_137_report_{SITE NAME}_{TITLE}_{GENERATED ID}.xls
Open the downloaded xls report to view the graphs and calculations.
Viewing a Report's Raw Data
It is also possible to view the raw data that was used to generated an Excel Spreadsheet report, click on the View button next to a report.
You will be taken to another screen, towards the top of the page you'll see data categorised into the time bins (20 to 100 and >100).
Towards the bottom of the page you can see the raw event data which was used to generated the binned values.
Duplicate a Report
If you want to run a new report with the same settings as an existing report but change only the dates (for example), you can click the Copy button next to an existing report.
This will copy the values from the selected report into the report generation form.
Delete a Report
To delete a generated report, click the Delete button on the report you wish to delete.
A confirmation dialog will prompt you to confirm the deletion.
