1.6.4 Recommended Configuration
Recommended configuration is based on fast periodic AVL data acquisition mainly according
to the change of the object’s geographic angle (Min.Angle = 10 degrees). According to this
configuration the FM1100 device will generate AVL record every time the object’s angle is changed
more than 10 degrees. Such AVL data acquisition is rational in cases the object mostly moves in the
city. Min.Distance = 100 meters, so the additional AVL record will be generated after driving more
than 100 meters in the straight line. If the object with FM1100 device is not moving, the AVL data
records are generated periodically every 1 hour (Vehicle on STOP Min.period = 3600 s). If the object
with FM1100 device is moving, the AVL data records are generated periodically every 300 seconds.
AVL data is sent via GPRS to the server as soon as the AVL data record is generated (Min.
saved records = 1; Send period = 1 s). According to this configuration one AVL data record,
containing information about the GPS position and Input/Output (I/O) parameters is sent to the
server at least every 300 seconds.
Following I/O elements’ vales are monitored in every AVL data record:
DIN1 (as ignition) {values: 0 –Off; 1 –On};
Movement {values: 0 –object is not moving; 1 –object is moving};
Power voltage {values: from 10 V to 30 V, according to the power source).
Speed {values: current vehicle speed in km/h}
Additional AVL data records called “events” are generated on following parameter value
changes:
If power voltage value falls to less than 11 V;
Speed is less than 5 km/h for more than 1 minute;
Ignition is turned ON/OFF (DIN1=1 or DIN1=0).
1.6.5 What is the purpose of testing FM1100 in this scenario?
The main purpose of this testing scenario is for the user to see the highly detailed track (as in
the sample screenshot below) of his driven track in the city. The user will be able to see his vehicles
current position as well as the position in any selected time in the past. The user will be able to see the
time and points in the map in which the ignition has been turned ON/OFF, power voltage has become
less than 11 V (car battery needs to be recharged). The user will be able to compare “Vehicle on
STOP” and “Vehicle MOVING” modes.
