Centrix stores analogue events for the electric current for DC Track Circuits and average current for AC Audio Frequency Track Circuits.
The electric current is high when the track is not occupied and drops when the track is occupied:
...
The 'Typical Behaviour' line shows the average clear and occupied values over the last 30 days. Overlayed on top of this is a specific occupation event.
Note: When displaying this data on these graphs, Centrix shows both clear regions as 25 percent of the length of the occupied region. This is so that all occupations should look similar to the user and ensure that they are easy to view and interpret.
Creating occupation events can allow Centrix to show high level information about Track Circuit Assets such as the number of occupations in the last time period (week / month / year etc.) and how many alarms have been raised as a fraction of total occupations in the last time period.
