This project is designed and developed
for helping the passengers traveling in train and bus especially during
night. The people who are not aware of the station on which
one should get down will find this very helpful. Here the station name
is displayed and announced simultaneously when the station is about to
reach which can assist both literate and illiterate.
The RF technology is used in the project
to communicate between the transmitter and receiver. Each transmitter
has a unique binary code which is transmitted continuously to space in a
particular range. This signal is captured by the receiver when it
reaches in its range. So in the case of a train, the transmitter placed
in the station is detected by the receiver in the train and the binary
code is processed to give out the station name display and audio
corresponding to the binary code in the receiver. A LCD unit is used for
displaying the station name and a speaker is used for the announcement.
