\gTrack system provides the means to control passengers doing regular
trips by special transport (for example, school buses or corporate
vehicles). RFID tags are commonly used for this purpose. Upon getting
into and out a vehicle, passengers bring their tags against a reader.
Received data is sent to gTrack Hosting where it can be further used for
the monitoring purposes.
Algorithm of controlling a passenger
RFID tag sends identical information upon bringing it against a reader.
Therefore, the algorithm should be used in order to establish a strict
line between getting into and out a vehicle:
The first operation of a RFID tag in
24 hours means a passenger gets into a vehicle. The second operation of
the same tag in the same vehicle means a passenger gets out. If the
second operation of the tag occurs in the same vehicle within 1 minute
after getting into/out, then it is considered to be a false one. Such an
operation is ignored by the system.
If a passenger gets into a vehicle
using RFID tag, and afterwards the same tag operates in the other
vehicle, then the system recognizes it as getting out of the first
vehicle and getting into the second one.
If no RFID tag operation detected
within 10 hours after a passenger gets into a vehicle using a RFID tag,
then such a passenger is recognized by the system as the one left a
vehicle.
To implement control over a passenger, it is necessary to create passengers in the interface of the monitoring system and form automatic binding lists. Data received from a RFID tag provides a possibility to implement online monitoring, generate reports on passengers, and send corresponding notifications.
