THIS PROJECT IS DESIGNED TO MAKE UNATTENDED
AUTOMATIC TOLL TAX STATIONS AT CHECK BARRIERS OR OCTRI CHCK POSTS

Automatic toll tax project is designed ,using
atmel 89c51 microcontroller & descreate
componants. Heart of the
project is an ir
transmitter and receiver modules ,these strong
powerfull modules
transmits 38khz strong
ir beam, has a range of more than 15 feets are sufficiently
enough for our project. I have designed this project as a simple
emplementation of the toll collection process automatically in a model
form. This should not be considered as a real toll collection system
which require much more considerations , tests and huge amount of money,
before they are actually put into use.
However this
project gives enough guidelines for
the actual dvelopment of
the toll collection system. For
the sake of simplicity , we have to make coin box exactly same as used in pco coin box machine fixed on railway station or else
whare. We have to make two coin size holes one for one rupee, and other
for five rupee coin. You have to fixup coin sensors on these holes, one
sensor should be fixed for five rupee coin and one sensor for one rupee
coin.
