ABSTRACT
Accident identification and alerting project is an existing project.
The previous proposed systems are aurdino
based consist of vibration sensor and gps and gsm modem. Arduino is
the heart of the system which helps in transferring the message to
different devices in the system. Vibration sensor will be activated
when the accident occurs and the information is transferred to the
registered number through GSM module. Using GPS the location can
be sent through tracking system to cover the geographical coordinates
over the area. The accident can be detected by a vibration sensor
which is used as major module in the system.
The problem with the proposed system is when ever
vehicle fell into some larger path holes vibration sensor get activated
and sending some false information to the registered person number
that accident had been occurred. So, now we are going to use MEME
sensors which predict the accident more accurately than these
vibration sensors. To detect the crash more accurately MEME sensors
are used with an advanced electronic control unit capacitance based
method and the server of the crash is easily determined ECU also take
input from the wheel speed sensors and gyroscopes and brake
pressure sensors and seat occupancy sensors.
INTRODUCTION
The development of the transportation system has become the driving
force for human beings to have the highest civilization on Earth. Cars
are very important in our daily life. We use it to go to work,
connect with friends and family, and deliver goods. But it can
also cause us problems and kill us in accidents. Speed is one of the
most important and important risk factors in driving. This not only
affects the severity of the accident, but also increases the risk of the
accident.
Although various governments and non-governmental organizations
around the world are making great efforts through various programs
to prevent reckless driving, accidents still occur frequently. However,
many lives could have been saved if emergency services had received
information about the crash in time. A study by Virtanen et
al. It shows that 4.6% of accident deaths can only be prevented
if timely emergency services can be provided at the scene of an
accident. Therefore, effective automatic accident detection, which
automatically informs emergency services along with the location of
the accident.
WORKING OF PROJECT:
• Arduino is Major control unit to communicate between devices
when an accident occurs which helps in transferring message to
different devices in the system
• GPS module will find the location of the vehicle and the information
is fetched by the receiver through the coordinates
• GSM modem will help to send sms whom ever registered their
number
• The accelerometer and gyroscope detect the accident occurrence
• The vibration sensor is also used to detect the accident by producing
voltage from the impact of vehicle movements

WORKING OF GSM
The GSM SIM900 module is preferred to enable
communication between GPS, GSM and dedicated mobile numbers. The
name SIM900 indicates tri-band operation in the frequency range from
900 MHz to 1900 MHz, such as EGSM900 MHz, PCS 1900 MHz and
DSC 100 MHz. The receive pin of the GSM module and the transmit pin
of the GPS module are used for communication
between modules. and cell phone.
Working of gps
To determine your position on Earth,
everything is split into some coordinates, and you can easily fix your
position with a module called a GPS module. A GPS SIM28ML
is used here. This GPS module locates the vehicle and receives the
information received by the GPS receiver through the coordinates, the
received data is first sent to the Arduino, and the information is sent to
the stored contacts through the GSM module. The frequency operates in
the 1575.42 MHz band and the output of the GPS module is in NMEA
format with real-time data such as location.
Working of aurdino
The Arduino UNO is a popular open
source microcontroller board based on the ATmega328P microcontroller
and developed by Arduino.cc. Arduino is the main control device that
detects or warns you in the event of an accident. It collects data from
vibration sensors, GPRS and GSM modules and displays the output as
a display system or message. Vibration sensors play an important role
here. This vibration sensor receives vehicle vibrations and acts
as an accident detection module. The Arduino collects information from
all other modules and sends messages to the receiver via the GSM module.
Working of gyroscope
A gyroscope is a device mounted on a
base such that its axis rotates freely in one or more directions so that a
rotating disk or wheel maintains its orientation regardless of movement of
the base. However, the direction changes to another in response to an
external torque.
\
MEMS sensor working principle :
whenever the tilt is appled to the MEMS answer then a balanced mass
makes a difference within the electric potential. This can be measured like
a change within capacitance then that signal can be changed to create a
stable output signal in digital, 4-20mA or VDC. These sensors are fine
solution to some applications which do not demand the maximum
accuracy like industrial automation position control role and pitch
measurement and platform leveling.
Types of memes
The common types of Memes sensors are obtainable with in the are:
Memes accelerometer
Memes gyroscopes
Memes pressure sensors,Memes magnetic field sensors
Simulation done using proteus:
Note: since mems sensor is not available in proteus
we procceded with the vibration sensor
The below simulation is designing using aurdino for
for this we are going to add pressure sensor to
achieve our objective
In the above diagram we are not getting the hex.file path at output of
aurdino programming to keep in the proteus simulation we are
working on it .
Once it is resolved we have to attach the pressure
sensor to our simulation and have to do some coding changes along
with it to run our project.
Error we are in proteus simulation.
Conclusion
The accident event detection system has been developed. The proposed
system is for incident notification and detection. It reads the exact latitude
and longitude of the vehicle where the accident occurred and
sends it to the nearest ambulance. Arduino helps pass
messages to other devices in the system. An accelerometer is used to
monitor the direction in which the collision occurred, and a gyroscope is
used to detect if the vehicle is overturning. The information is sent to the
registered number via the GSM module. GPS allows you to include
geographic coordinates for each region by sending your location
through a tracking system.
Contribution
The proposed system contributes to the reduction of deaths
from accidents. Accidents that have occurred are detected
using the proposed methodology. You can also use the GPS module to
pinpoint the scene of the accident and use the GSM module to send a
warning message to emergency medical services so you can
reach the scene on time, saving people life This feature can help
reduce the mortality rate from accidents.
