[Discussion] Smart Helmet: Ride Bike Securely and Smartly!

Hello, Mi Fans!
Road accidents are on the rise day by day, and in countries like India where bikes are more prevalent many people die due to carelessness caused in wearing motorcycle helmets. Even though there has been the continuous awareness from the government authorities regarding helmets and seat belts a majority of the drivers do not heed them.
In order to put an end to this misery, we have developed the smart helmet for motorcycle, a way to stop starting of vehicles without wearing a helmet or even if the driver is boozed. In addition, it has a great feature of detecting accidents and informs specific people via SMS with location and speed of the bike before the accident occurs with the help of GPS GSM based tracking system, thus aiding ambulance to reach the correct location.We have implemented all the sensors within the helmet, which will send the information to the module connected with the bike engine wirelessly. A display is provided to monitor the status.


This smart bike helmet system has two modules, one on the helmet and another one on the bike. Accident sensor, helmet sensor, and alcohol sensor are attached with the helmet module and GPS and GSM are connected with the module on the bike that has displayed to monitor status. These two modules communicate wirelessly using RF transmitter and receiver with encoder and decoder, PIC16F877A is used as CPU.This is one of the most advanced electronics projects for engineering students.


Working of smart helmet for motorcycle.

Helmet module
  • The three sensors- alcohol, accident and the helmet sensors are assembled here; it will run with a 9V battery. The 7805 linear regulator IC connected to the circuit will convert 9V to 5V.
  • This circuit contains RF transmitter, Encoder, sensors, and regulator. The output from each of the sensors is connected to the data input pins of the encoder (AD9, AD10, and AD11). The encoder will continuously encode and these sensors values are fed to RF transmitter to transmit data to the ECU unit for further actions.
  • All the sensors we have used here is digital (TTL output) to makes our system easier.
  • The push button is used here as helmet sensor i.e. it will detect the wearing of a helmet.It must be pushed off type i.e. in normal condition it will be ON and when pushed it will be OFF.
  • Alcohol sensor must be placed in front of the mouth to check alcohol content in the breath.
  • A vibration sensor is used to detect an accident, so it should be placed on the helmet where vibration occurs when the helmet hits the ground.

ECU module
  • This system includes GPS module, GSM module, PIC microcontroller, RF receiver and decoder
  • RF receiver receives signals from the helmet module and are decoded by decoder IC HT12D
  • The decoder is directly connected to PORTE, it is continuously scanned by PIC and does the required actions.
  • The relay is used to short the spark plug to a ground; normally vehicle body is connected to ground.
  • In normal case spark plug is shorted to ground, it will disconnect from the ground only after wearing a helmet and when no alcohol is detected.
  • The vibration sensor is fixed on the helmet, if an accident occurs it will detect and send signals through RF, it will send SMS to the specified number with the accident location and vehicle speed just before the accident had occurred.
  • LCD display shows the status of the system- detection of alcohol, accident detection, the speed of the vehicle and accident location.
