eye blink sensor accident prevention seminar report
Vehicle accidents are most common if the driving is inadequate. These happen on most factors if the driver is drowsy or if he is alcoholic. Driver drowsiness is recognized as 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. But the life lost once cannot be re-winded. Advanced technology offers some hope avoid these up to some extent.
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. The IR receiver is used to receive the reflected infrared rays of eye. If the eye is closed means the output of IR receiver is high otherwise the IR receiver output is low. This to know the eye is closing or opening position. This output is give to logic circuit to indicate the alarm.
This project helps in controlling accidents due to unconsciousness through Eye blink. Here one eye blink sensor is fixed in vehicle where if driver looses consciousness, then it is indicate through alarm.
A car simulator study was designed to collect physiological data for validation of this technology. Methodology for analysis of physiological data, independent assessment of driver drowsiness and development of drowsiness detection algorithm by means of sequential fitting and selection of regression models is presented.
INTRODUCTION
Vehicle accidents are common if he 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.
Working Procedure of Sensor
The eye-blink sensor illuminates the eye with infrared light, monitoring the changes in the reflected light.
The output is active high for Eye close and can be given directly to micro-controller for interfacing applications.
Consequently a buzzer is activated in order to wake the driver.
The motor of the vehicle is slowed down through a relay switch so as to prevent impending accident.

Motor Driver-L293D
L293D is a dual motor driver integrated circuit (IC) Act as current amplifiers. This higher current signal is use to drive the motors.
L293D contains two inbuilt driver circuits.
In common mode of operation, two DC Motors can be driven simultaneously, both in forward and reverse direction.
Enable pins 1 & 9 (corresponding to the two motors) must be high for motors to start operating.
Buzzer
A signaling device, usually electronics, typically used in automobiles, household appliances.
Usually illuminates a light on the appropriate button or control panel.
Sounds a warning in the form of a continuous or intermittent buzzing or beeping sound.
LCD Display
Consists of two lines, 20 characters per line.
3 control lines and I/O Lines.
8 data pins D700
RS : Register Select
R/W : Read or Write
E : Enable (LATCH DATA)
Software Used
MikroC is a powerful, feature rich development tool for PIC Micro-controllers.
Provides the programmer with easiest possible solution for developing applications for embedded systems, without compromising performance or control.
Advantages of Project
The prime purpose is to provide safety Measures.
IT is used for Automatic Parking.
It can be used in wireless technology.
The eye blink module of this project can be separately used for RFID detection in global Industries.
It can be used in image processing application by MERA MODULE.
