Abstract - In present time many cases of bike accident
can be seen around us. peoples get injured or might be
dead and one of the reason is not wearing helmet.
Many peoples could save their life in accident cases if
they weared helmet at the time of accident.
Continuously road rules are violated. So as to overcome
these problems, an Smart helmet is proposed having a
control system built inside a helmet. Smart Helmet for
Motorcyclist is a project undertaken to increase the rate
of road safety among motorcyclists. The idea is
obtained after knowing that the increasing number of
fatal road accidents over the years is cause for concern
among motorcyclists. It consist a RF transmitter and a
RF receiver system. the bike will not get start without
wearing helmet by the user, as user wear helmet a rf
signal radiate from transmitter and once these rf signal
get sensed by the receiver placed in the ignition switch
of the bike, bike will get start. Security system applied
in this project meet the characteristics of a perfect rider
and the application should be highlighted. The project
is expected to improve safety and reduce accidents,
especially fatal to the motorcyclist.
INTRODUCTION
In today’s era, especially in the young generation, the
craze of motorbikes is really remarkable. The middle class
families prefer to buy motorbikes over 4-wheelers,
because of their low prices, various varieties available in
the market, due to cut-throat competitions between 2-
wheeler companies and durability. As the bikers in our
country are increasing, the road mishaps are also
increasing day by day[1], due to which many deaths occur,
most of them are caused due to most common negligence
of not wearing the helmets, also many deaths occur due to
lack of prompt medical attention needed by the injured person. This motivates us to think about making a system
which ensures the safety of biker, by making it necessary
to wear helmet, as per government guidelines, also to get
proper and prompt medical attention, after meeting with
an accident. The project aims at the security and safety of
the bikers against road accidents. The circuit is so
designed that the bike wont’ start without wearing helmet
It introduced a security system on the rider with the
perfect helmet usage before riding.in this system no
advanced concepts of JAVA Programming (JavaScript, j2me)
and Microcontroller 8051 based circuitry is used[2].based
on RF link simple working and operation. By using RF
transmitter and RF receiver, the motorcycle can be moved
if it receive signal from the helmet .Here our main object is
to design the circuit that can improve the safety of
motorcyclists. [3]The statics of law breaker is depicted
below in table.
2.2 Technical Description
This radio frequency (RF) transmission system employs
Amplitude Shift Keying (ASK) with transmitter/receiver
(Tx/Rx) pair operating at 434 MHz. The transmitter
module takes serial input and transmits these signals
through RF. The transmitted signals are received by the
receiver module placed away from the source of
transmission.
The system allows one way communication between two
nodes, namely, transmission and reception. The RF
module has been used in conjunction with a set of four
channel encoder/decoder ICs. Here HT12E & HT12D have
been used as encoder and decoder respectively.
3. RF TRANSMITTER SECTION
Encoder IC (HT12E) receives parallel data in the form of
address bits and control bits. The control signals from
remote switches along with 8 address bits constitute a set
of 12 parallel signals. The encoder HT12E encodes these
parallel signals into serial bits. Transmission is enabled by
providing ground to pin14 which is active low. The control
signals are given at pins 10-13 of HT12E. The serial data is
fed to the RF transmitter through pin17 of HT12E.
RF RECEIVER SECTION
In simple terms, HT12D converts the serial input into
parallel outputs. It decodes the serial addresses and data
received by, say, an RF receiver, into parallel data and
sends them to output data pins. The serial input data is
compared with the local addresses three times
continuously. The input data code is decoded when no
error or unmatched codes are found. A valid transmission
in indicated by a high signal at VT pin and then relay goes
on. A string of address and data bit is used to prevent from
false triggering
5. APPLICATION
Useful for school students.
Useful for bike and scooters.
Help to protect life in accident case.
Number of cases of voilated traffic rules can be
reduced.
6. RESULT
Smart helmet for safe rider is designed with radio
frequency link. , as user wear helmet a rf signal radiate
from transmitter and these RF signal get sensed and
synchronized with the help of address matching by the
receiver section placed in the ignition switch of the bike
and bike get started and bike stopped working as helmet
keep out from head. This means bike work properly till
helmet keep on head.
7. CONCLUSIONS
This system is very effective for the safety purpose of the
user. User has to wear helmet to ride two wheeler vehicle
and hence traffic rules will follow with this. This system is
under pocket control ie. Ride two wheeler vehicle having
safety in hand and in budget also. Easy functioning to
operate this system. It provides a better security to the
biker.
