Plug-ins for saving and downloading the vehicle data
By activating certain plug-ins, you can take the vehicle data that are temporarily stored
in TEMS Manager and save them permanently on the Traffic Controller FPS and/or can
transfer them to an external storage medium.
The plug-ins support various storage formats and transfer methods.

Saving vehicle data on the Traffic Controller FPS
The
CSV Export
and
Disk Storage
plug-ins are both used for saving vehicle data on the
Traffic Controller FPS.
•
The
CSV Export
plug-in saves the vehicle data obtained to a tabular csv file, which is
located inside the
/lists
directory. A separate table row is created in the csv file for
each vehicle. As part of this process, you can also specify the period to be covered by a
file. Usually, a csv file contains the vehicle data for a particular day. This makes the csv
file very suitable for statistical purposes.
The time stamp appears in UTC time as the reference time.
•
The
Disk Storage
plug-in stores each detected vehicle in a separate file using the
vehicle
file format. The vehicle file is placed in the
/data
directory.
The vehicle file contains all the information recorded for a vehicle. In addition to the
vehicle data, it includes (among other things), the 3D point cloud data or information
about when and where the vehicle was located within the measuring range when the
data was collected.
•
Please note that the storage space is limited. The storage space is overwritten cyclically
for as long as the plug-ins remain active.
•
For both plug-ins, you can specify in the parameter definition how often the vehicle
data should be deleted from the Traffic Controller FPS data memory (see also chapter
6.7.1 Displaying the system parameters and system status
). The delete operation is
only performed if the plug-ins are active.
•
If the plug-ins have been deactivated, the data inside the
/data
and
/lists
directories
must be deleted
manually
.
•
Any directories that you have created in or under the FTP directory must also be
deleted manually. This process is not automated either.
•
When there is no space left on the internal memory card, the data from the Traffic
Controller must be overwritten. This shortens the service life of the Traffic Controller.
