    1. 1. VEHICLE ACCIDENTPREVENTATION USING EYE BLINK SENSOR PROJECT GUIDE D.KISHORE M.Tech(Ph.D)
    2. 2. ABSTRACT Accidents are increasing at a large pace, and various technologies are being introduced to reduce the accidents. Inthis project we provide by means of accident prevention using eye blink where as the vehicle is stopped immediately and intimated wherever needed.
    3. 3. OVERVIEW INTRODUCTION BLOCK DIAGRAM OF TRANSMITTER BLOCK DIAGRAM OF RECEIVER MICROCONTROLLER PIN DESCRIPTION EYE BLINK SENSOR AND COMPARATOR CIRCUIT RF COMMUNICATION ENCODER AND DECODER MOTOR POWER SUPPLY UNIT LCD DISPLAY LCD INTERFACING SOFTWARE SED PROGRAM CONCLUSION FUTURE SCOPE
    4. 4. INTRODUCTION Vehicle accidents are most common if the driving is inadequate. Driver drowsiness is recognized as an important factor in the vehicle accidents. This project involves measure and controls the eye blink using IR sensor. The IR transmitter is used to transmit the infrared rays in our eye.

    6. 6. BLOCK DIAGRAM OF TRANSMITTER EYE Blink RF Sensor Transmitter Microcontroller AT89S52 comparator Encoder
    7. 7. BLOCK DIAGRAM OF RECEIVER DC Motor RF Receiver Microcontroller Buzzer AT89S52 Decoder LCD Display
    8. 8. MICROCONTROLLER(AT89S52) Pin Diagram
    9. 9. Pin Desciption Low power, high performance CMOS 8 bit microcontroller. 8K bytes of Flash, 256 bytes of RAM, 32 I/O lines two data pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture VCC PSEN GND EA/VPP PORT 0 XTAL1 PORT 1 XTAL2 PORT 2 PORT3 RST ALE/PROG
    10. 10. RF COMMUNICATION
    11. 11. RF COMMUNICATIONTRANSMITTER:• Low Cost• 1.5-12V operation• Small sizeRECEIVER:• operates at 4.5 to 5.5 volts
    12. 12. ENCODER &DECODER
    13. 13. MOTOR (L293D) L293D Pin description Logic Diagram Functional description
    14. 14. POWER SUPPLY UNIT
    15. 15. LCD DISPLAY• LCD display consists of two lines, 20characters per line.• 3 control lines and 8 I/O lines. - 8 data pins D7:D0 - RS: Register Select - R/W: Read or Write - E: Enable (Latch data)
    16. 16. LCD INTERFACING
    17. 17. SOFTWARE USED Keil compiler is the software used where the machine language code is written and compiled. The machine source code is converted into hex code, this hex code is dumped into the microcontroller for further processing.

PROGRAM#include<reg51.h>//#include<lcd.h>sbit s1=P1^4;sbit s2=P1^5;sbit s3=P1^6;sbit s4=P1^7;sbit r1=P1^0;sbit r2=P1^1;sbit r3=P1^2;sbit r4=P1^3; sbit rs=P3^7;sbit en=P3^6;void delay(unsigned int ch) //delay function { unsigned int i=0,j=0; for(i=0;i<=ch;i++) { for(j=0;j<=i;j++) { } } } void clcd(unsigned char ch){ P2=ch; rs=0; en=1; delay(15); en=0;}
    19. 19. void dlcd(unsigned char ch) { P2=ch; rs=1; en=1; delay(15); en=0; } void stringlcd(unsigned char ch,unsigned char *chrt) { unsigned int ix=0; if(ch==0x80) clcd(0x01); clcd(ch); for(ix=0;chrt[ix]!=0;ix++) { dlcd(chrt[ix]); } } void initlcd() { clcd(0x38); clcd(0x0e); clcd(0x06); clcd(0x01); clcd(0x80); ◦ } void main(){P1=0x00;initlcd();stringlcd(0x80,"hai");
    20. 20. while(1){ if(s1==0) //front { r1=1; r2=0; r3=1; r4=0; stringlcd(0xc0,"front "); } else if(s2==0) { r1=0; r2=1; r3=0; r4=1; stringlcd(0xc0,"back "); }else if(s3==0){ r1=1; r2=0; r3=0; r4=1; stringlcd(0xc0,"left "); } else if(s4==0){ r1=0; r2=1; r3=1; r4=0; stringlcd(0xc0,"right ");} else { r1=0; r2=0; r3=0; r4=0;stringlcd(0xc0,"stopped ");} delay(300);
    21. 21. CONCLUSION Reduce the number of accidents. It is also used for security alerts where 24 hours surveillance is required.
    22. 22. FUTURE SCOPE This is extended with alcoholic detection also. If the person took alcohol who is driving then the vehicle will be stopped immediately by giving alarm .s
