2.  Accidents are increasing at a large pace , and various
technologies are being introduced to reduce the accidents.
Accidents due to drowsiness ,increased stress level and
sudden heart attack are prevented and controlled when
the vehicle is out of control. In this project ,we provide
accident prevention using different sensor simulation
where as the vehicle is stopped slowly an driver status is
transmitted to nearby hospital(using GPS technology) for
immediate rescue operation.

3. LITERATURE SURVEY
STEERING ASSIST CONTROL SYSTEM ON CURVED
ROAD USING CAR-TO-CAR COMMUNICATION
In this paper, we assume that there is a lead vehicle
in front of the host vehicle within the detection range of the
car-mounted sensor and it can detect its relative position.
First, a virtual road boundary estimation method is
proposed based on measurement of the relative position of
the lead vehicle and the lead vehicle status obtained by the
car-to-car communication method.

5. INTRODUCTION
 Vehicle accidents are common if the driving is inadequate
These happen on most factors if the driver is drowsy or
stressed or physically sick(low heart beat level).
 Driver drowsiness & sudden physical problem is an
important factor in the vehicle accidents . It was
demonstrated that driving performance deteriorates with
increased drowsiness with resulting crashes constituting
more than 20% of all vehicle accidents.
 This project involves measure and control the eye blink
rate, stress level & heart beat level using different sensor
And The output of the sensors are cumulated to transmit
driver status to server(i.e. nearby hospital)

MODULES

16. MODULE 1:Program analysis and interfacing with LCD
Keil Compiler:
 The C programming language is a general-purpose,
programming language that provides code efficiency,
elements of structured programming, and a rich set of
operators. Many applications can be solved more easily
and efficiently with C than with other more specialized
languages.
 The Cx51 Optimizing C Compiler is a complete
implementation of the American National Standards
Institute (ANSI) standard for the C language.
 Cx51 provides you the flexibility of programming in C
and the code efficiency and speed of assembly language.

17. Compiling with CX51:
This explains how to use Cx51 to compile C source
files and discusses the control directives you may specify.
These directives allow you to perform several functions. For
example:
• Direct Cx51 to generate a listing file
• Control the information included in the object file
• Specify code optimization and memory models
.

18. Interfacing with LCD
 The LCD display consists of two lines, 20 characters per
line that is interfaced with the PIC16F73. The display
contains two internal byte-wide registers, one for
commands (RS=0) and the second for characters to be
displayed (RS=1).
 It also contains a user-programmed RAM area (the
character RAM) that can be programmed to generate any
desired character that can be formed using a dot matrix.
 To distinguish between these two data areas, the hex
command byte 80 will be used to signify that the display
RAM address 00h will be chosen Port1 is used to furnish
the command or data type, and ports 3.2 to 3.4 furnish
register select and read/write levels.

The Pin diagram for LCD is shown below

20. MODULE 2: Hardware Analysis
Heart beat sensor:
 Heart beat sensor is designed to give digital output of
heat beat when a finger is placed on it.
 OUT Active high output.
 GND power supply ground.

21. DC MOTOR
 A direct-current motor is a shunt-wound motor in which
the field windings and the armature may be connected in
parallel across a constant-voltage supply.
 Torque:0.3 to 18.5 ounce-inches.
 Size: From 20mm to 52mm
 Cost-effective rotary motor control.Dc motor is fully
reversible.

22. UART
 A UART is usually an individual (or part of an)
integrated circuit used for serial communications over
a computer or peripheral device serial port. UART are
commonly used in conjunction with other
communication standards such as EIA RS-232.
 The MAX232 is an integrated circuit that converts
signals from an RS-232 serial port to signals suitable
for use in TTL compatible digital logic circuits.
 The drivers provide RS-232 voltage level outputs
(approx. ± 7.5 V) from a single + 5 V supply via on-
chip charge pumps and external capacitors.

23. Circuit Diagram
The receivers reduce RS-232 inputs (which may be as high
as ± 25 V),to standard 5V TTL levels.These receivers have
a typical threshold of 1.3 V,and a typical hysteresis of 0.5 V.

24. RELAY
 A relay is an electrically operated switch. Current flowing
through the coil of the relay creates a magnetic field which
attracts a lever and changes the switch contacts.
 Relays allow on circuit to switch a second circuit which can
completely separate from the first. For example a low
voltage battery circuit can use a relay to switch a 230V AC
mains circuit. There is no electrical connection inside the
relay between the two circuits, the link is magnetic and
mechanical.

25. Circuit Diagram
 500mA rated collector current(Single output)
 High-voltage outputs: 50V

26. WSN
 WSN is a specification for a suite of high level
communication protocols using small, low-power digital
radios based on the IEEE 802.15.4-2003 standard.
 Power consumption constraints for nodes batteries or
energy harvesting.
 Ease of use.
 Ability to withstand harsh environmental
conditions.
 Mobility of nodes

27. Circuit diagram

28. MICRO CONTROLLER
 The AT89S52 is a low-power, high-performance CMOS 8-
bit microcontroller with 8K bytes of in-system
programmable Flash memory.
 4.0V to 5.5V Operating Range.
 Fully Static Operation: 0 Hz to 33 MHz.

29. LIQUID CRYSTAL DISPLAY(LCD)
 Liquid Crystal Display (LCD) consists of rod-shaped
tiny molecules sandwiched between a flat piece of
glass and an opaque substrate. These rod-shaped
molecules in between the plates align into two
different physical positions based on the electric
charge applied to them.
 When electric charge is applied they align to block the
light entering through them, where as when no-charge
is applied they become transparent.

34. MODULE 4: Displaying driver status in VB
application
 Visual Basic (VB) is an ideal programming language for
developing sophisticated professional applications for
Microsoft Windows.
 Coding in GUI environment is quite a transition to
traditional, linear programming methods where the user is
guided through a linear path of execution and is limited to
small set of operations

35. DESCRIPTION
 In server side a simple vb application is created
which displays the eye blink and heart beat level.
 Also 2 buttons in the application are used to control
the vehicle anytime from the server side.
 In order to provide help, the vehicle location is
tracked with the help of L10 QUECTUEL
EXTERNAL ANTENNA.
 The antenna gives the longitudinal and latitudinal
value of the vehicle in correct location , help can be
provided to the driver at any serious condition.
Therefore this system ensures safe driving

37. CONCLUSION:
This is because of the fact that the driver is not able to
control his vehicle when he is asleep and by the time he
realizes it, there is an accident. The vehicle is at a very
high speed on highways due to which handling is tough
and getting the vehicle to halt in such a condition is
difficult. Due to this many automobile companies are
trying to research onto how an accident which occurs due
to driver fatigue can be prevented.

38. In this project we will generate a model which can
prevent such an incident. The Purpose of such a model
is to advance a system to detect fatigue symptoms in
drivers and control the speed of vehicle to avoid
accidents. The main components of the system
consists of an eye blink sensor for driver blink
acquisition and an adaptive speed controller designed
using stepper motor for providing precise positioning of
the throttle valve to control the speed of vehicle.
Advanced technology offers some hope avoid these up
to some extent.

39. FUTURE ENHANCEMENT
Since GPS signals are based on signal level. When
there is low signal for instance in some interior places
there is loss of signal level.in such case it is possible to
transmit the driver status to nearby vehicle by same
GPS technology.
Hence the proposed system includes a warning
signal to the nearer vehicle drivers. Automatic alert
message sending to the nearer vehicle drivers can be
proposed.
