1. Dynamic Supervision and broadcast System for optimal driving System for
Wireless Helmet
Abstract:
Now a day’s wearing helmet is becoming very essential. A helmet works exactly like your skull. Made
from fiberglass and thermoplastic it acts like a shell for protecting your brain. The inside of a helmet is lined with
expanded polystyrene (EPS) of controlled density. When the helmet is struck with a hard surface, the inner lining
acts as a buffer and absorbs the shock. It bears the sudden change in energy and pressure and keeps the skull
intact. The EPS may crush but it still protects the skull. Government has laid many rules for wearing the
helmet. Even tough public isn’t showing their interest in wearing it. Since wearing the helmet is good for
people’s life. We have designed the wireless helmet which will be very useful for the people. By using
this system people can drive their vehicle safely and comfortly.
In this proposed system we have used a wireless communication between bike to helmet and bike to
bike. The system will be comprised of a helmet module including stereo speakers and microphone, and a
bike mounted base unit. The system will make use of different wireless communication protocols
including Bluetooth and another radio frequency (RF) protocol with the intent to eliminate all physical
connections between the rider and the motorcycle. The helmet module will communicate with the bike
module using a Bluetooth signal.
BLOCK DESCRIPTION:
HELMET SECTION:
The main objective of the system is to eliminate all physical connections between the rider and
the motorcycle. The helmet system is designed with stereo speakers, microphone & a wireless
communication device. By using this system user can communicate with the bike wirelessly. For example
if the rider wants to on the right indicator isn’t necessary to do it physically. Rider can just say right in a
microphone which is placed in his helmet then the data is wirelessly transferred to the bike section using
Bluetooth.

2. VEHICLE SECTION:
In vehicle section data from the helmet are received wirelessly through Bluetooth and it
activates the device accordingly. Fuel indication unit is used to find the present fuel level and it displays
the distance up to which it can travel in LCD. Intruder sensor is used to indicate the rider if any obstacles
are present or any bike comes near it. Using RF module nearest signal status can be intimated
depending on the signal status the rider can driver faster or slower.
