5.3 Regular GPS data reporting
GPS data can be sampled by 3 means: by time interval, by distance or by heading change.
They can be enabled or disabled separately, only sampled by time interval is enabled by
default.
The sample rate for time interval can be 2-600s and default setting is 30s, for distance
interval can be 50-5000m and default setting is 500m, for heading change can be 5-90
°
and
default setting is 15
°.
There can be single or several groups of GPS data in one GPS message, determined by
groups of GPS data per message, device will not report GPS message until it has collected
specified groups of GPS data. Groups of GPS data per message can be 1-30 and default
setting is 1.
For example, sampled by time interval and sampled by distance are enabled, and the
respective settings are 10s and 500m, groups of GPS data per message is 5. Assume that
vehicle is running at speed of 72km/h (20m/s), then it takes 25s to run out of 500m, so GPS
data are sampled at 10th, 20th, 25th, 30th, 40th second and reported at 40th second as 5
groups of GPS data have been collected at that time.
The suggested minimal interval for GPS report is 10s. For example, if only sampled by time
interval is enabled, then the settings might be 10s of sample rate and 1 group of GPS data
per message, or 5s of sample rate and 2 groups of GPS data per message.
5.4 Regular G-Sensor Data Reporting
Device reports G-Sensor data (g-value of X/Y/Z axis) according to configured time interval,
this function is disabled by default.
The sample rate can be 200-6000ms and default setting is 1000ms.
There can be single or several groups of G-Sensor data in one G-Sensor message, determined
by groups of G-Sensor data per message, device will not report G-Sensor message until it has
collected specified groups of G-Sensor data. Groups of G-Sensor data per message can be
50-100 and default setting is 100.
5.5 Regular Diagnostic Data Reporting
(CAN required)
Device is able to read variety of vehicle diagnostic data, also called PID (parameter ID),
including vehicle speed, engine RPM, engine coolant temperature, mass flow air, etc, and
report up to 10 types of PID data according to configured time interval.
The sample rate can be 2-600s and default setting is 60s.
There can be single or several groups of PID data in one PID message, determined by groups
of PID data per message, device will not report PID message until it has collected specified
groups of PID data. Groups of PID data per message can be 1-30 and default setting is 1.
