FINAL YEAR PROJECT 1 (WEEK 2): What is smart helmet by using microcontroller?

Objectives: 

1) To give an overview about my FYP

2) To make an introduction about my FYP

Methods:

1) By making researches in the internet

2) By searching the technology devices used in the project

Results:

This project is about safety helmet which is basically provided for motorcyclist. It is called as a smart helmet as it it very useful when the motorcyclist had an accident on the road. The smart helmet consists of GSM technology so that it can send SMS to give information about the accident to the ambulance and family members. Other than that, GPS technology also makes the smart helmet is a very useful as it can extract the location of the accident which contains the latitude and longitude values about accident's place. It is included in the SMS so that the ambulance will have the information about the accident occured. Furthermore, pressure sensor also used in the project as it can detect whether the motorcyclist wearing the helmet or not. the motorcycle cannot starts if the person does not wearing it. The alcohol sensor also used in this project for a safety reason as it can sense the alcoholic content whether the motorcyclist is drunken or not. if the alcohol sensor detects it, the motorcycle cannot start as the alcohol detected on LCD display. Another thing that can be very helpful for this smart helmet is vibration sensor. when the motorcyclist had a crashed, the helmet hits the ground and the vibration that had created when the helmet hits on the ground detects by vibration sensor. The microcontroller used for this project is P89V51RD2 type which is also 80C51 microcontrollers. The LED is ON to indicates that power is supplied to the circuit when the system is switch on. The RF is used for start the two wheeler firstly by checking whether the motorcyclist is drunken or not. The motorcycle cannot starts if the motorcyclist is drunk. In normal condition, the helmet has a pressure sensor which senses pressure and the RF transmitter radiates the FM modulated signal. The RF receiver is connected with the motorcycle which is receiving the radiated signal and the relay activate after it. The relay is remove the ignition wire from the ground and connected with the starter switch and the motorcycle will start. When driver met with accident vibration sensor sends message to microcontroller which means that the smart helmet is very safe to use as the system has been circulated starting from when the person wear the helmet until the person met an unexpected accident. 

Conclusion:

This week I am going to give an overview about my final year project at title smart helmet by using microcontroller. There are many technologies that can be used to create the smart helmet such as by using Arduino. This project can be improvise by placed a speed limiter as to restrict driving at high speed. Other than that, it is also can improved by using solar energy to power the circuit so that it uses green energy and does not harm to environment. This project can decrease the case of accidents between the motorcyclists besides can save more lives.
