The Development Of A Drunk Driving Detection System With Car Ignition Control System (PDF/DOC)

Overview

ABSTRACT

The Nigerian government has been advising its citizens not to drink and drive for decades, but for the first time, it may be able to physically stop you from getting behind the wheel while hammered.

The main purpose behind this project is “Drunk driving detection”. Now a days, many accidents are happening because of the alcohol consumption of the driver or the person who is driving the vehicle. Thus Drunk driving is a major reason of accidents in almost all countries all over the world. Alcohol Detector in Car project is designed for the safety of the people seating inside the car.

This device measures alcohol intake, displays percentage of alcohol and also automatically shutdown the engine of the car the drunk person is driving (or about to drive) if it is above a particular threshold. Here we use an alcohol sensor circuit along with LCD display and a relay for shutting down the system

INTRODUCTION

This work discus about alcohol sensing alert with engine cut-off system. Nowadays, higher percentage of accident that occur on high ways are caused by drinking alcohol – drunk drivers. So here we propose an innovative system to eliminate such cases. Our proposed system would be constantly monitoring the driver breath by placing it on the driver wheel or somewhere the drivers breath can be constantly monitored by it. So if a driver is drunk and tries to drive the system detects alcohol presence in his/her breath and locks the engine so that the vehicle fails to start. In another case if the driver is not drunk while he starts the vehicle and engine is started but he/she drinks while driving the sensor still detects alcohol in his breath and stops the engine so that the car would not accelerate any further and driver can steer it to roadside. In this system we use an an arduino microcontroller with an alcohol sensor along with an LCD screen and a dc motor to demonstrate the concept. So here the alcohol sensor is used to monitor users breath and constantly sends signals to the microcontroller. The microcontroller on encountering high alcohol signal from the alcohol sensor displays alcohol detection note on LCD screen and also stops the dc motor to demonstrate as engine locking. The system needs a push button to start the engine. If alcohol is detected at the time of starting the engine the engine does not start at all. If alcohol is detected after engine starting, the system locks the engine at that time.

1.1 BACKGROUND OF THE STUDY

The Nigerian government has been advising its citizens not to drink and drive for decades, but for the first time, it may be able to physically stop you from getting behind the wheel while hammered.

The main unit of this project is an “Alcohol sensor”. If the person inside car has consumed alcohol then it is detected by the sensor. Sensor gives this signal to a comparator IC. The output of comparator is connected to the arduino microcontroller. Microcontroller is the heart of this project. It is the CPU of the complete circuit. Microcontroller gives high pulse to the buzzer circuit and the buzzer is turned on. At the same time a relay is turned off. Due to this the ignition of the car is deactivated [4].

1.2 PROBLEM STATEMENT

Nowadays major accidents occur on road because of increase in traffic and rash or asleep driving of the drivers. Several accidents occur attributable to consumption of alcohol. So alcohol dinked driving is additionally vital reason for accident happens. The alcohol detection in-car system is supposed for the cover of humans seating within the car and in several things, would like the auto and police authority isn’t hip in time. Because of this kind of accident, the help given to the sufferer is delayed.

1.3 OBJECTIVE OF THE PROJECT

The objective of this work is design a drunken driving detecting device, which detects the percentage of alcohol and displays the same on an LCD display. It also sounds an alarm if the amount of alcohol exceeds a particular amount.

1.4 PROJECT MOTIVATION

There is such a large amount of car users who drove a car with Consumption of alcohol, which is the reason for a most of car accidents. Also once Associate in an accident occurs at non-residential place or highways, in this condition most important is to offer primary aid (healing) service to injured human by the support of ambulance. So it was also necessary to include accident detection as well as location detection and this info given to the nearest police/ ambulance emergency service center help of wireless media like SMS (Short Message Service). This can help to reduce the number of accidents occur due to alcohol drunk consumption. In several car accidents there is a possibility of fire. Therefore during this dangerous situation to save individuals people life with the help of fire fighting blower to stop fire yet as data given to the nearest, police station, fire brigade and ambulance emergency service center. Proper seat belt detection is better than traditional seat belt detection. Sometimes there is a possibility of misuses safety harness lock using directly attach of extra safety harness buckle without pull of safety harness by a driver. Therefore car system detects attach the safety belt. By reducing this sort of misuse of safety harness detection within the vehicle, therefore necessary to detect correct seat belt [12].

1.5 PURPOSE OF THE PROJECT

The main purpose behind this project is “Drunk driving detection and automatic automobile engine lock”. Thus Drunk driving is a major reason of accidents in almost all countries all over the world. Alcohol Detector in Car project is designed for the safety of the people seating inside the car.

1.6 APPLICATIONS OF THE PROJECT

Applications of Alcohol Detector in Car:

1) “Alcohol Detector project” can be used in the various vehicles for detecting whether the driver has consumed alcohol or not.

2) Breathing analyser project can also be used in various companies or organization to detect alcohol consumption of employees. Alcohol detection system in an automobile is a must feature which every cab or bus should have [2].

1.7 SIGNIFICANCE OF THE PROJECT

“Alcohol Detection System in Cars” provides an automatic safety system for cars and other vehicles as well.

The sensors can also aid an officer in the detection of alcohol during a stop, not to replace other more reliable and effective testing methods. This equipment helps provide law enforcement with tools to develop initial suspicion of someone breaking the law. Because they lack the precision of other tests and can detect alcohol from sources other than the suspected impaired driver [20].

1.8 ADVANTAGES OF THE PROJECT

To prevent accident due to drunk and driving.
Easy and efficient to test the alcohol content in the body.
Quick and accurate results.
Helpful for police and provides and automatic safety systems for cars and other vehicles as well.

1.9 PROJECT ORGANISATION

The work is organized as follows: chapter one discuses the introductory part of the work, chapter two presents the literature review of the study, chapter three describes the methods applied, chapter four discusses the results of the work, chapter five summarizes the research outcomes and the recommendations.

CHAPTER FIVE

5.1 CONCLUSION

These conclusions are the basis of the study of drinking driving. They can provide some references for the discrimination of drinking driving state and making countermeasure to it. At the same time, they also support the study of driving safety and the research on drivers’ driving model, especially for safety driving.

Determining the alcohol concentration in expired air for monitoring compliance with the blood alcohol limits is important particularly in the area of testing one’s ability to drive in traffic. For this application it is necessary to develop inexpensive alcohol sensors in order to provide versatile expedient hand-operated instruments.

In addition to determining the alcohol concentration in expired air, alcohol content following alcohol consumption can also be detected on the skin. This provides the possibility for continuously measuring alcohol content without the active cooperation of the person being tested, and hence is ideal for monitoring persons who are, for example, in emergency medical situations.

5.2 RECOMMENDATION

This project is designed to be used in cars and checking points for the security of drivers, passengers and vehicles. And should be used and maintain by a qualified personnel.
