Accident Alert System using Advance Microcontrollerijtsrd
In India most of the accidents are happening due to vehicles over speeding. Sometimes if obstacle is close to the vehicle then they won't be able to judge the distance to apply instant brakes and accident is occurred. To avoid accident due to over speeding, obstacle detection using ultrasonic sensors is used. In this project ultrasonic sensor is used for 360degree detection of obstacle. If obstacle is in front of the vehicle less than safety distance, automatically brakes will be applied or if vehicle comes from backside of the vehicle and is at less than safety distance then the warning light is shown to vehicle. Sometimes if vehicle is coming very close to our vehicle just before hit the vehicle the airbags are open.

IRJET- Performance Study on IR Obstacle Sensor for Automobile Braking SystemIRJET Journal
This document presents a study on using an infrared obstacle sensor for an automobile braking system. The system uses an IR sensor to detect obstacles in front of a vehicle. When an obstacle is detected within a certain distance, based on the vehicle's speed and braking distance calculations, a microcontroller and Arduino would automatically apply the brakes. The goal is to minimize accidents by taking human reaction time out of emergency braking situations. The system includes an IR sensor, Arduino microcontroller, relays to control brakes, and a motor driver circuit. It is proposed that this automatic braking control system could be installed in vehicles to help prevent accidents and save lives.

I. INTRODUCTION
Generally diving a vehicle is a common thing nowadays,
peoples generally use automobile to travel from one
destination to other. The number of automobiles are
increasing day by day. Nowadays, number of accident are
maximizes. Accidents happened frequently and it cause
serious injury and death also. This accidents are generally
causes due to slow response to apply the brake. The main
objective of this project to design speed control & automatic
braking system in the vehicle. That the driver may not brake
it manually but the vehicle can stop automatically due to
obstacle.
The main objective of this project automobile can
run automatic braking due to obstacle when obstacle is to be
detected by the sensors. The function of braking circuit is to
apply the brake after detection of obstacle.
The basic objective of these paper is to developed
and smart braking system using ultrasonic sensor and to
design a vehicle with less human attention to the driving and
to increase the safety of the driver and passengers.
II. OBJECTIVE OF WORK
1) To increase the sureness of braking Application.
2) To reduce the requirement of internal safety devices
like air bags.
3) To provide safe parking.
4) To avoid damage of vehicle.
5) To provide comfort for driver with regarding driving
purpose.
6) To provide additional brake in addition to conventional

III. LITERATURE REVIEW
Dhanya K. R. [1] has proposed a technology of an advance
automatic braking system with sensor fusion concept. In this
they uses the properties of both capacitive &ultrasonic
sensor for detecting the obstacle & also for calculating the
distance between the vehicle & the obstacle and this
distance measurement is used to control automatic braking
system for safety application. In this system they use the 32-
bit microcontroller with ARM processor(LPC2138) as the
brain of this system for controlling process. The
programming is done by using c-language. The additional
feature included in the system are automatic retarding &
automatic horn disabling in restricted area, this is done
through RF signal communication. The RF transmitter is
placed in restricted area, where the speed is limited & horn
is restricted. RF transmitter placed in the traffic signal,
transmit the value of limited speed in km/hr & a signal
corresponding for disabling horn and then automatically
reduce speed into particular rate & horn is disabling in that
area.
S. P. Bhumkar [2] presents a system of about
accidents avoidance & detection on highways. This system
is about advance technology in cars for making it more
intelligent & interactive for avoiding accidents on roads.
ARM7 is using for making this system more
efficient, reliable & effective. In this system, they have
described real-time online safety prototypes that control the
vehicle speed under driver fatigue. The purpose of this
system is to avoid accidents. The main component of this
system consist of number of real time sensor like gas, eye
blink, alcohol, fuel impact sensor & a software is interface
with GPS & Google maps APIs for location. Through this
research work, they have proposed an intelligent car system
for accident prevention & making the world a much better &
safe place to live.
Vidyadhar M. [3] presents a system that can
enhance the safety of vehicle. This system give solution can
assist the driver by warning the driver about impeding
obstacle & approaching vehicle that may lead to collision in
addition to this they are also implementing & auto retarding
system which helps in avoiding accidents. In this system
ultrasonic sensor, motor driver and LCD are used. In
addition to this, they have implemented an automatic wiper
speed control which control speed of wiper is based on the
intensity of rainfall. In the wiper speed control system the IR
sensor is very sensitive & can detect very small quantities of
moisture. In case even slight rainfall the system will get
activated, in higher amount of rain the motor faster & will
implies the wiper runs faster & save the driver from
distraction & provide convenience & safety.
IV. METHODOLOGY

After studying the different techniques of braking
system it is clear that electrical supply & compressed air
supply is the source require for braking application. The
distance from obstacle where vehicle is supposed to be stop,
compressed air supply, stroke of pneumatic cylinder, speed
of vehicle and deceleration of the vehicle are the important
parameters.
It is decided to plan and proceed with Ultrasonic Sensor
and Flow Control Valve made up of metal and with Air
Medium and 230V A.C. and 50 Hz for its performance
analysis involving experimental and necessary instruments
for measurement of pressure in valves, hose and collector.
Also high pressure compressed air is supply towards
pneumatic cylinder. A separate compressor is used to
compressed the air. The experiment is carried out on one
wheel only.
The proposed method will automatically inform to
driver about the obstacle in the path of the automobile on the
LED display with the obstacle distance with ultrasonic
sensor. The driver takes different actions based on these
signals to create a safe drive. When the distance between
two obstacle is reach upto it’s limiting distance, means if
accidents like situation are detected by ULTRASONIC
sensor then the automatic pneumatic braking system is
activated.
A. Obstacle Detection.
The objective of the obstacle detection is to control
deceleration of the vehicle and secure the comfort and safety
of the driver against different types of obstacle. To get these
results ultrasonic sensors are attached on front sides of the
vehicle. The ultrasonic Sensor has one transmitter and one
receiver. The transmitter of the ultrasonic sensor will
continuously transmit the signal. When these transmitting
signals will collide with any hurdles and will be reflected
back, the receiver of sensor will receive these reflected
signals and forward them towards controller.
B. Signal Transmission.
The obstacle detected by ultrasonic sensor and it will
transmit the signal to the driver. On the LED display driver
will see the distance of obstacle. The controller will take the
actions for the comfort drive if in any case the controller
was unable to take the actions then the system will send
signal to the flow control valve and it will open the
compressed air flow.
C. Activation Of Pneumatic Braking System
The primary objective of braking system is to control the
vehicle or stop the vehicle in case of emergency. The
controller of the vehicle is not able to take action then,
signal will transmit towards the flow control valve of 50 Hz
and it will supply the compressed air supply. The
compressed air supply is actuate the pneumatic cylinder
which is attached to the brake lever and it will retard or stop
the vehicle.
V. LIST OF COMPONENTS
There are various types of components such as ultrasonic
sensor, flow control valve, double acting pneumatic cylinder
are to be used while studying the subject.
A. Pneumatic Cylinder
Here we are using and double acting cylinder. DAC is a
cylinder in which the working fluid acts alternately on both
sides of the piston.
Here we are using the pneumatic cylinder of air
medium and temperature limit up to 0°c to 85°c. of diameter
25mm and of bore diameter of 50mm.
The function of the piston is to move forward when
flow control valve is open and to apply the brake and retard
the vehicle.

B. Ultrasonic Sensor
The range of ultrasonic sensor is upto 400cm so it will
detect the object within it and it will show it on LED to the
driver. The brake will apply within the limited distance
which is has been setup by the controller. The sensor will
contain the one is transmitter and other is receiver.

VI. DESIGN OF PISTON
A. Thickness of Piston
The thickness of the piston head is calculated from flat-plate
theory
t = D (3/16 x P/f) ½
Where,
P - Maximum combustion pressure = 100 bar
f - Permissible stress in tension = 34.66 N/mm²
Piston material is aluminium alloy
.∴t = 0.050 (3/16 x 100/34.66 x 106
/105)½
x 1000
= 12 mm
B. Length of the Piston
Length of the piston = 1.625 x D
Length of the piston = 81.25 mm
Length of the piston skirt =Total length – Distance of first
ring from top of
The first ring (No. of landing between rings x
Width of land) – (No. of compression ring x
Width of ring)
= 81.25 – 5 – 2 x 1.875 – 3 x 2.5
= 65 mm
C. Design of Pneumatic Cylinder
Force to be exerted is 40N
Force = pressure x Area
Pressure in the cylinder = 0.4 x105 N/m2
Area of the piston, (πd2
)/4 = Force/pressure
= 40/ 40000
= 0.001m2
Bore diameter = 0.0356m = 35.6 mm
From pneumatic products catalogue we have selected 40mm
bore diameter cylinder
For Forward Stroke
For 40mm bore diameter
Corresponding rod diameter = 16mm
Area of the piston = (πd2
)/4
= (πx402)/4
= 1256.8mm2
Force (modified) to be exerted = pressure ×area
= 0.4 x105 x1256.8
= 50N
For Return Stroke
On the return stroke, when the pressure is applied to the
reverse direction, the force on
The Piston due to the pressure is
= P × (A-a)
Where,
P = Pressure in the cylinder (N/m2
)
A = Area of the piston (m2)
a = Cross sectional area of the piston rod (m2
)
Therefore
Area of the piston (A-a) = {(π× d2
)/4}-{(π× d1
2
)/4}
= {(π× 402
)/4}-{π (×162
)/4}
= 1256.6-201
= 1055mm2
Force To Be Converted
On the reverse direction = Pressure Area
= 0.4× 105×1055
= 42.2 N
For working pressure of 0.4×105 N/m2
Extending force = 50.3 N
Retracting force = 42.2 N
VII. ADVANTAGES AND DISADVANTAGES
1) Free from wear adjustment
2) Less power consumption
3) It gives simplified very operation.
4) Installation is simplified very much
5) Need separate air tank
6) In this system there is no speed controlling system
7) Addition cost is required to install this system to four
wheeler.
VIII. FUTURE SCOPE
The future scope of these study give us benfits of reduction
in stress, decreased in accidents and safe and secure drive
for younger drive. The further study of these system will
give us the better results in safety and comfortness of the
vehicle. Drivers need to be better informed about situations
in which their system is unlikely to react. Based on the
potential safety benefits and problems more research is
needed to determine the overall safety impact of these
systems. The future scope of the system is implementation
on hardware. These system can be improved by including
the buzzer or light indicator and can be able to set the speed
in the vehicle by using the keyboard and keyboard encoder
in the system.
IX. CONCLUSION
In this paper work we have conclude that the pneumatic
braking system has an wide effort on safety and comfort.
Paper work suggests that there are safety benefits from using
pneumatic brake as a technology, such as reduction in speed,
applying brakes at safer distances. This technology also
avoid the skidding of vehicles due it’s speed controlling
technology. As ultrasonic sensors can detect any kind of
obstacle, this system can also prevent collision of the
vehicle with pedestrians, or can at least reduce the injuries
occurring.
