ABSTRACT
As we all know that there is cheating & corruption
all around. Top to bottom everyone everywhere looks
for the place to earn extra money, in better words easy
money.
Hate to admit this but auto rickshaw meter
tampering in India is quite common. The drivers get
away with their devious plan because the current meter
calculates fare based on the rotations of the wheel of
the vehicle. This system can be easily tampered with.
Finally the burden comes on the shoulder of the
middle class public. And big amount they pay extra as
fare.
Keywords: Bluetooth communication, automatic metering,
industrial automation, microcontroller, embedded system
I. INTRODUCTION
An auto rickshaw/Taxi is a vehicle for hire, and it is one
of the chief modes of transport in India. A large number of
people use these vehicles for their daily transportation and
every time they pay extra amount as fare because there is
no check on the reading of meter available.
Hence, it is necessary that we should have something
that can cross check the reading of the meter and guide us
the right fare amount.
This daily problem of the public encouraged us to work
in this area and we came up with an idea of FAIR FARE
SYSTEM for social benefit of all.
II.
BACKGROUND OVERVIEW
A. Existing System
The calculation of fare amount is calculated on the basis
of no. of wheel rotation of the vehicle. There is no such
system available which can check weather the calculation
shown by the meter is correct or not.
If the driver has tempered the meter the fare amount
shown will be high but as no crosschecking is done the
passengers are forced to pay the extra money.
B. Drawbacks of Existing System




Tempering the current system is very easy.
Passengers are forced to pay extra.
Increases corruption and malpractices in society.
Creates burden on the pocket of the public.
C. Proposed System
Our proposed system will have a circuit inbuilt in the
existing meter and will send the count of wheel rotation on
Bluetooth frequency with the help of Bluetooth modem.
This data can be received on the mobile of passenger after
pairing their mobile with the Bluetooth device of the meter
with the help of the meter id printed on the meter.
The software in the mobile will calculate the fare
amount on the basis of the data received by the meter.
Now passenger can cross check the fare amount between
mobile reading and the meter reading. If there is difference
then one can easily point out that there is tempering in
meter. The passenger will pay as per mobile reading only.

C. Explanations of Blocks
The following are the brief explanations of the working
principle of the various major blocks or sections used in
the system…
 Power Supply
This unit will supply the various voltage
requirements of each unit. This will be consists of
transformer, rectifier, filter and regulator. The
rectifier used here will be Bridge Rectifier. It will
convert 230VAC into desired 5V/12V DC.
 Microcontroller
This unit is the heart of the complete system. It is
actually responsible for all the process being
executed. It will monitor & control all the
peripheral devices or components connected in the
system. In short we can say that the complete
intelligence of the project resides in the software
code embedded in the Microcontroller.
The controller here user will be of 8051 family.
The code will be written in Embedded C and will
be burned or programmed into the code memory
using a programmer.
This unit requires +5VDC for it proper operation.
 LCD 16x2
It is called Liquid Crystal Display. We are going to
use 16x2 character LCD. This will be connected to
microcontroller. The job of LCD will be to display
all the system generated messages coming from the
controller. LCD will provide interactive user
interface.
This unit requires +5VDC for it proper operation.
 555 Timer
The 555 monolithic timing circuit is a highly stable
controller capable of producing accurate time
delays, or oscillation. Here we are using it in
Astable Multivibrator mode for generating clock
pulses. The frequency depends upon the external
register connected to the IC.
This unit requires +5VDC for it proper operation.
 Bluetooth Modem
Bluetooth Modem is a device that acts as mediator
between any embedded system and the Bluetooth
communication medium. It has built-in protocol
for serial communication i.e. Serial Port Profile.
Thus it provides an ideal solution for developers
who want to integrate Bluetooth wireless
technology into their design with limited
knowledge of Bluetooth and RF technologies.
This unit requires +3.3VDC for it proper operation.
 IR Tx
This is basically Infrared Transmitter that emits
light in the range of 10-6-10-3 wavelength(m). This
light is not visible by human eye and hence mostly
used in security systems for proximities.
This unit requires +1.5VDC for it proper operation.
IR Receiver is nothing but a photodiode that break
down the diode junction when exposed to IR rays.
Thus it can be used for activation & deactivation of
particular system.
D. Features
The Following are the prominent features of the above
discussed system…
 Any Mobile can be paired with any meter,
 Mobile software will increment FARE as per
government rule,
 Real time increment as soon as meter starts,
 No cheating possible with passenger,
