INTRODUCTION
“DOCTORS COME AFTER ACCIDENT
BUT WE ENGINEERS CAN PREVENT
ACCIDENT”

4.
World is plagued by accidents.
Human errors
Need an alert for the driver
Checking the speed of the car is
important

5.
ACCIDENT
High speed leads to
accidents.
Accident =
short distance
+
high speed

6% of the worlds road accident deaths
happen in India.

BLUETOOTH
Bluetooth can communicate
with 8 other devices
simultaneously
Hence we can check the speed
of 8 cars simultaneously
Range of communication is up to
100 meters of each other
100 mts

9.
Equipment
The group of 8 devices is known as
PICONET.
PICONET is a collection of master
and slaves .
The frequency of 2.4GHz is
shared among all the devices in the
piconet.

10.
Equipment
 Master is a device
which controls all
the devices around
it.
Slave is a device
which is being
controlled by a
master.
• Here A,B are masters and S1 to S6 are the
slaves.

11.
>100 mts.
• If the distance between two
vehicle is within the 100m the
Bluetooth devices get enabled.
<=100 mts.

12.
•If the distance come closer
within 10m the automatic
braking system takes the
control.
<10 mts.

13.
COMPONENTS
1)Speed sensors
2)Pump
3)Valves
4)Controller

14.
• Short distance, low power radio
operating in the unlicensed
spectrum of 2.4 GHz and using a
nominal antenna power of 20
dBm.
• At the 20 dB the range is 100
meters, meaning equipment must
be Within 100 meters to each
other (about 328 feet) to
communicate using the
Bluetooth standard.
• With the help of this technology
we can send data to the eight
devices.

15.
Automatic braking pump and valves
A computer constantly monitors the distance
between each of these cars
When its senses that the car is getting too
close it moves the hydraulic valves to increase
pressure on the braking circuit
It effectively increasing the braking force on
the wheels

16.
• Controls the speed of the car.

AUTOMATIC BRAKING SYSTEM

17.
FUNCTIONS OF HYDRAULIC VALVES
In position one the valve is opening
,pressure from the master cylinder is passed
right through to the brake.
In position two the valve blocks the line
,isolating that brake from the master cylinder
This prevents the pressure from rising
further should the driver push the brake
pedal harder
In position three, the valve releases some of
pressure from the brake

18.
Advantage
It reduces the accident rate
It gives the alert to driver
Its maintenance is low
This technology gives safety

19.
Disadvantage
Every car must and should have
Bluetooth to communicate with
each other
Due to the automatic braking
system the throttle valve get
damage
The automatic braking system is
some what costlier

20.
• The Bluetooth technology is being widely
adopted by the Industry leaders.
• The possibility for new applications is very
exciting with this Versatile technology.
• It provides a simple, logical answer to all the
Problems-which is built a single common
radio into every mobile computer.
• It neither do companies have to worry about
WAN, nor do communication companies need
to worry about building external cables.
