Abstract: A smart helmet is a special idea which makes motorcycle driving safer than before. This is implemented
using GSM and GPS technology. The working of this smart helmet is very simple, vibration sensors are placed in
different places of helmet where the probability of hitting is more which are connected to microcontroller board.
So when the rider crashes and the helmet hit the ground, these sensors sense and gives to the microcontroller
board, then controller extract GPS data using the GPS module that is interfaced to it. When the data exceeds
minimum stress limit then GSM module automatically sends message to ambulance or family members.
INTRODUCTION
The thought of developing this project comes to do some good things towards the society. Day by day the two wheeler
accidents are increasing and leads to loss of many lives. Accord to a survey of India there are around 698 accidents
occurring due to bike crashes per year. The reasons may be many such as no proper driving knowledge, no fitness of the
bike, fast riding of bike, drunken and drive etc. Some time the person injured, the accident may not be directly responsible
for the accident, it may be fault of rider, but end of the day it’s both the drivers involved in the accidents who is going to
suffer. If accidents are one issue, lack of treatment in proper time is another reason for deaths. According to the survey
India 698 accidents occur per year, nearly half the injured people die due to lack of treatment in proper time. The many
reasons for this such as late arrival of ambulance, no persons at place where the accident occur to give information to the
ambulance or parents.
This is a situation we observe our day to day life, a thought of finding some solution to resolve this problem come up with
this idea of giving the information about accident as soon as possible and in TIME….!!!!Because after all time matters a
lot, if everything is done in time, at least we can save half the lives that are lost due to bike accidents.
Considering three major factors for avoiding the accident causes such as I. Make wearing the helmet compulsory. II.
Avoid drunk and drive. III. If person met with an accident, no one is there to help him. Simply leaving or ignoring the
person he may die. In such situation, informing to ambulance or family members through mobile to rescue him for an
extent.
The idea of this work is to give information about the rider wearing the helmet or not, whether the rider drunken or not
and also, he met with an accident it gives an information about location where he is met with an accident through GSM
module to mobile numbers family members, so I have chosen GSM technology to give the information by sending SMS,
using GSM module which has SIM card slot to place the SIM and send SMS. Sending SMS alone can’t help the driver, if
we send and an SMS saying that accident had occurred where the ambulance will come without knowing the location of
the accident. So to trace out the location where exactly accident occur using GPS module, and gives to microcontroller,
then it sends the SMS which contains the latitude and longitude of a area to family members mobile numbers For this we
use GPS module to extract the location of the accident, the GPS data will contain the latitude and longitude values using
which we can find the accurate position of the accident place.
Hardware Software Description
The P89V51RD2 are 80C51 microcontrollers with 64kB flash and 1024 bytes of data RAM. A key feature of the
P89V51RD2 is its X2 mode option. The design engineer can choose to run the application with the conventional 80C51
clock rate (12 clocks per machine cycle) or select the X2 mode (six clocks per machine cycle) to achieve twice the
throughput at the same clock frequency. The flash program memory supports both parallel programming and in serial ISP.
Parallel programming mode offers gang-programming at high speed, reducing programming costs and time to market. ISP
allows a device to be reprogrammed in the end product under software control. The capability to field/update the
application firmware makes a wide range of applications possible.
LCD display
LCD (Liquid Crystal Display) screen is an electronic display module and find a wide range of applications. A 16x2 LCD
display is very basic module and is very commonly used in various devices and circuits. These modules are preferred over
seven segments and other multi segment LEDs.The reasons being LCDs are economical easily programmable have no
limitation of displaying special & alphanumeric characters A 16x2 LCD means it can display 16 characters per line and
there are 2 such lines.
Software required is keil’s software for run the code and to dump the code into controller using flash magic. Using
assembly language to write the code for the system.
ADC0809
ADC0809 is an 8-bit analog to digital converter. It is used to convert the analog voltage of temperature sensor and battery
circuit. The reference voltage of ADC0809 is 5V. It is an 8 channel ADC. The temperature sensor is connected to channel
0 and battery circuit is connected to channel 1.The 8-bit A/D converter uses successive approximation as the conversion
technique. The converter features a high impedance chopper stabilized comparator, a 256R voltage divider with analog
switch tree and a successive approximation register. The 8-channel multiplexer can directly access any of 8-single-ended
analog signals.
Vibration Sensor
This sensor buffers a piezoelectric transducer. As the transducer is displaced from the mechanical neutral axis, bending
creates strain within the piezoelectric element and generates voltages. The Vibration Sensor Detector is designed for the
