ADVANCED SMART HELMET WITH ALCOHOL DETECTION AND ENGINE LOCK FOR ENHANCED RIDER SAFETY

Abstract

One of the main causes of traffic accidents nowadays is drunk driving. There are a significant number of fatalities in cities. A 2021 survey found that, with 57,221 reported incidents annually, Tamil Nadu had the highest number of drunk driving accidents in India. We’re working on a "smart helmet" that can determine if the driver has consumed alcohol and stop the motor. We incorporated methods for both prototypes and real-time applications in our analysis. In real­time implementation, the Electronic Control Unit, or ECU, is an essential part. To explain the main idea of our research, we developed a prototype using an Arduino Uno and a MQ-3 alcohol sensor. Our study focusses on two-wheelers, whereas current research on alcohol detection is conducted for four-wheelers. By encouraging more people to wear helmets when driving, this smart helmet idea would lower the amount of fatalities brought on by traffic accidents.

Specification

The following technical description goes into extensive detail about both the invention itself and the process in which it is to be carried out.

Driving under the influence (DUI) or driving while intoxicated (DWI) is a serious crime, involving operating a vehicle with a blood alcohol content (BAC) level of 0.08% or higher. Those most at risk of DUI are binge drinkers or individuals with alcohol use disorders, who consume excessive amounts of alcohol in a short period. Alcohol absorption into the bloodstream occurs within 30 to 120 minutes, impairing breathing and cognitive abilities, and posing significant risks to both the driver and others on the road. Individuals driving under the influence often struggle to respond to emergency situations. Findings from a 2008 investigation conducted by the World Health Organization indicate that approximately 50%- 60% of traffic accidents are linked to alcohol impairment, with drunk driving emerging as the leading cause of fatal car accidents.

Design an automatic system for alcohol detection and engine lockout technology specifically for two-wheelers.

The brain of the system is a microcontroller (such as an Arduino of Raspberry Pi), which processes information from the alcohol sensor and determines whether to start the engine. In the event that alcohol is discovered, it is linked to the car's ignition system to immobilise the engine. To make sure the helmet is worn properly and the alcohol sensor is actively monitoring, some research looks into wireless communication modules (such as Bluetooth and RF). An essential layer of safety can be added by successfully preventing an intoxicated rider from starting the vehicle by connecting the alcohol sensor to the engine's ignition system, according to research. The literature emphasises that the helmet's weight, comfort, and ventilation shouldn't be sacrificed in order to
incorporate sensors.
To keep the system usable and feasible for everyday usage, advanced materials and ergonomic designs are frequently suggested. Additionally, some publications suggest integrating GPS and GSM systems to alert authorities or emergency contacts in the event that someone tries to start the car while
intoxicated.
44 SUMMARY OF INVENTION
Approximately 3341 fatalities are attributed to drunk driving each year. These kinds of accidents can be avoided with the use of smart helmets. The goal of

this effort is to stop drunk driving incidents, utilising technological and practical solutions. Building on current four-wheeler prototypes, we want to develop a two-wheeler-specific alcohol detection and engine locking prototype. Fixing the alcohol detection equipment in helmets makes detection simple and eliminates the need to change the two-wheeler's design. This project could significantly lower the number of drunk driving-related traffic accidents. Traffic cops will also find this quite useful. Two-wheelers and other vehicles are automatically protected by engine lockout and alcohol detection. Additional tragedies or crises can be avoided if the engine is automatically locked. This can save other people's lives as well as the life of the driver. This strategy will help society in many ways, such as increased economic development and traffic safety. 4.4 DETAILED DISCRIPTION OF THE INVENTON
Alcohol detection and engine lockout technology designed specifically for two- wheelers. This concept combines alcohol detection with engine locking, specifically for two-wheelers. The detecting equipment will be integrated inside the helmet, making it compatible with all two-wheeler models. The prototype uses a MQ-3 alcohol sensor and a relay to automatically turn off the motor when alcohol is detected. The Arduino UNO is the key component for signal
transfer.
In real-time applications, an alcohol sensor detects the presence of alcohol and sends the level to an Arduino UNO. The signal is then sent to a relay module, causing the engine to turn off automatically. This concept combines alcohol detection with engine locking, specifically for two-wheelers. The detecting


euipment will be integrated into the helmet, making it applicable to all two ­wheeler models. The prototype uses an alcohol sensor (MQ-3) to detect alcohol and a relay to turn off the motor automatically. The Arduino UNO is the primary component for signal transfer. Real-time applications can use the same alcohol sensor to monitor alcohol levels and send the signal to an Arduino UNO, which can then activate a relay.
