Wireless Transfer of Dynamic Event Data using RF Module |

-
If there are various violation data while the bus is in operation,
when it arrives
at
the garage,
the violation data is sent wirelessly (by RF Module).

Violations include speeding,
driving with doors opened, sudden starts and stops.

If there are
violating vehicles based
on the wirelessly transmitted data, the
corresponding vehicle¡¯s hard rack can be collected and searched closely in the office.

In addition, when the driver gets in an accident, they are embarrassed
& forget
to
record the time of accident.
If they did not record the time, it must be searched
on
an estimation with loss
of time.
- To avoid such loss of time, a switch is installed on the left
side of the driver¡¯s seat, separately
from the DVR so that the driver can press the Accident Button to automatically
record the time of the accident on the DVR.
-
Then this accident
time is recorded together in the event recording section.

Just like when violations occur, if the accident time is selected
on the list, the time is searched to play the video. |
