INTRODUCTION

“DOCTORS COME AFTER ACCIDENTBUT WE ENGINEERS CAN PREVENT

ACCIDENT”

World is plagued by accidents.

Human errors

Need an alert for the driver

Checking the speed of the car is important

ACCIDENT

High speed leads to accidents.

Accident = short distance+ high speed

STATISTICS1 2 3

61 person dies every 6 minutes 10 are injured in the same frame Indias share of global car accidents is 10%

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

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.

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.

>100 mts.

• If the distance between two vehicle is within the 100m the Bluetooth devices get enabled.

<=100 mts.

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

<10 mts.

COMPONENTS 1)Speed sensors

2)Pump

3)Valves 4)Controller

• 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.

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

• Controls the speed of the car.

AUTOMATIC BRAKING SYSTEM

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

Advantage

It reduces the accident rate

It gives the alert to driver

Its maintenance is low

This technology gives safety

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

• 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.
