Smart Helmet with Motorbike unit for Accident and Rash Driving Detection

Abstract

Reckless driving and drinking and driving are some of the most common causes of accidents. Youth riders usually ride very recklessly leading to accidents. The aim of the projects is to solve these problems. The project consists of a helmet unit (HU) and a motorbike unit(MU). The HU and MU communicate via RF using the NRF24L01 Module. The helmet unit continuously monitors the pulse rate of the rider, alcohol in the breath of the rider, and vibration intensity. The ignition system of the bike is activated only when the readings of the pulse rate sensor are cross the threshold. The motorbike unit has GPS and GSM module which send messages with the position of the rider in case of a mishap. Both units have an accelerometer for accident detection. The MU checks for approaching vehicles, rash driving, and accidents. Upon detection of alcohol in the breath of the rider or if the rider is met with an accident the ignition system of the bike is turned off, the buzzer starts beeping, the name and number of an emergency contact start flashing on the OLED screen, and a message with the location of the user is sent to the emergency numbers. If the rider is safe the rider can press the push button switch and a rider safe message will be sent. The LIDAR sensor in the motorbike unit helps in alerting the rider from vehicles approaching from behind. The motorbike unit is also fitted with IR sensors and ultrasonic sensors which detect the position of hands and legs of the rider respectively. The accelerometer fitted in the bike is capable of identifying the orientation of the bike. Upon detection of rash driving or approaching vehicles, a message is displayed on the OLED screen and the buzzers start beeping.
