We have an option to built in the Vehicle Tracking Device in the DCU or have it
an independent micro-controller based device with built-in GPS interface and GPRS modem. If it is made external
then the Controller unit is connected to the Vehicle Tracking device through RS232C serial port. The Vehicle
Tracking Device reads the current location of the vehicle and other parameters like speed etc. from the GPS device
at regular internal. It passes this information to the central VTS Server through GPRS connection. Additionally,
it passes this information to the Controller Unit on serial port.
The Controller unit uses the location information to identify the current and/or next stop on the route and
make the requisite voice announcement.
The Controller unit uses the GPRS modem of the tracking device to send data / messages to the central Server
(back office). The data shall include captured video data from cameras, ticketing information received from the
ETMs etc.
The Vehicle Tracking Device also supports a set of I/O ports through which it can monitor various
parameters of the vehicle fuel Level & theft prevention, Oil Pressure, Temperature, speed of engine,
Speed of Vehicle and other subsystem.
