Dynamic Supervision and broadcast System for optimal driving System for Wireless HelmetAbstract: Now a day’s wearing helmet is becoming very essential. A helmet works exactly like your skull. Madefrom fiberglass and thermoplastic it acts like a shell for protecting your brain. The inside of a helmet is lined withexpanded polystyrene (EPS) of controlled density. When the helmet is struck with a hard surface, the inner liningacts as a buffer and absorbs the shock. It bears the sudden change in energy and pressure and keeps the skullintact. The EPS may crush but it still protects the skull. Government has laid many rules for wearing thehelmet. Even tough public isn’t showing their interest in wearing it. Since wearing the helmet is good forpeople’s life. We have designed the wireless helmet which will be very useful for the people. By usingthis 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 tobike. The system will be comprised of a helmet module including stereo speakers and microphone, and abike mounted base unit. The system will make use of different wireless communication protocolsincluding Bluetooth and another radio frequency (RF) protocol with the intent to eliminate all physicalconnections between the rider and the motorcycle. The helmet module will communicate with the bikemodule using a Bluetooth signal.BLOCK DESCRIPTION:HELMET SECTION: The main objective of the system is to eliminate all physical connections between the rider andthe motorcycle. The helmet system is designed with stereo speakers, microphone & a wirelesscommunication device. By using this system user can communicate with the bike wirelessly. For exampleif the rider wants to on the right indicator isn’t necessary to do it physically. Rider can just say right in amicrophone which is placed in his helmet then the data is wirelessly transferred to the bike section usingBluetooth.
VEHICLE SECTION: In vehicle section data from the helmet are received wirelessly through Bluetooth and itactivates the device accordingly. Fuel indication unit is used to find the present fuel level and it displaysthe distance up to which it can travel in LCD. Intruder sensor is used to indicate the rider if any obstaclesare present or any bike comes near it. Using RF module nearest signal status can be intimateddepending on the signal status the rider can driver faster or slower.REQUIREMENTS:Hardware development tools Integrating unit RF module Bluetooth module Voice recognition moduleSoftware development tools OrCAD design Programming IDE Cross compilers Flash Magic
