A low power intelligent helmet system

Abstract

A low power intelligent helmet system is reported in this paper which ensures the safety of a two-wheeler rider. The primary concept behind the working of the system is that the ignition of a two-wheeler will be enabled only if the rider is wearing a helmet and not consuming alcohol. An alcohol sensor and helmet wearing sensitive switches are installed inside a helmet, which is connected wirelessly to the motorbike. The helmet is powered by a lithium ion battery which in turn is charged manually or by a solar panel, integrated outside the helmet. A fully functioning prototype of the reported switch based helmet system has been fabricated and all the necessary circuits are embedded inside the helmet and the motor bike. The proposed system has the unique characteristic of transmitting the appropriate condition of the signals for a predefined duration, followed by holding of these signals for the rest of the time at the receiving end for the proper functioning of the motorbike. Also, the alcohol detection circuit is automatically shut “OFF” after a predefined time. These features of the system results in around 15 times lesser power consumption.
