SAAVPS Smart Helmet

Introduction

The SAAVPS (Sobi Anti-Alcohol Vehicles Protection System) is a two-wheeler anti-alcohol vehicle protection system designed to reduce road accidents caused by drunk driving. Road accidents are a major problem worldwide, with thousands losing their lives daily due to various issues, including intoxicated driving.

In Nepal, a developing country with challenging road conditions, accidents are often attributed not only to poor road quality but also to drunk driving. SAAVPS aims to address this by preventing intoxicated individuals from operating motorcycles.

How It Works

The system integrates sensors within a full-face helmet. Upon booting, it checks if the rider is wearing the helmet properly. If not, the motorcycle engine won't start. If the helmet is worn correctly, the system sends specific RF (Radio Frequency) signals to the motorcycle's engine to allow it to start.

An alcohol sensor positioned near the rider's mouth continuously monitors their breath for alcohol concentration ranging from 0.04mg/l to 4mg/l. Should alcohol be detected, the sensor outputs an analog voltage which is recognized by the microcontroller. The microcontroller then stops sending RF signals, triggering a relay mechanism that shuts down the engine for a specified period, thereby preventing the intoxicated individual from riding.

Visual Demonstration

Sensors Used

• Alcohol Sensor: Detects alcohol concentration between 0.04mg/l to 4mg/l in the rider's breath and outputs an analog voltage corresponding to the level detected.
• Helmet Position Sensor: Determines if the helmet is worn correctly. If not, it prevents the motorcycle from starting.

Traffic Safety Awareness

Impact

By integrating SAAVPS into motorcycles, we can significantly reduce accidents caused by drunk driving. This system promotes responsible riding and enhances road safety, potentially saving countless lives.

Call to Action

Support the adoption of SAAVPS to make roads safer and save lives through innovative technology.
