Automatic Fire Initiated Braking and Alert System for Trains
By every new day alternative technologies are being developed which in turn are helping to increase the speed of trains. Indian Railways aims to increase the speed of its passenger trains to 140 -- 180 km/h on conventional tracks. Thus it can be seen from the trending aspects of railways that they are primarily focusing on increasing the speed rather than the SAFETY of the passengers. The primary focus should be the safety of passengers. Generally it is seen that when a train compartment catches fire due to any reason it's not easy to detect the fire initially and react to it. Due to which train does not stop instantly, which results in casualties and heavy damage to train. The objective of this paper is to design an Automatic Fire initiated braking and alert system for trains. This system consists a micro controller, motor, fire and smoke sensor, alarm, and alert system. This paper proposes an embedded system that will be used to alert people so that life as well as the damage can be minimized. If the train coach catches fire, the smoke sensor will sense it and send a signal to the micro controller. This micro controller activates the motor to pull the chain and also activates an emergency alert system which sends an alert message to the train driver and guard room and activates the alarm. If the chain system to stop the train does not work properly, then even in that case, this system is very effective. So this system is useful to protect precious lives of passengers and minimize the heavy damages due to the fire accidents.
