Railway Security System based on ZIGBEE Technology

Abstract

A system for preventing trains from derailing and colliding with hazards on railways is disclose. Railway safety is a crucial aspect of rail operation the world over.. This paper is designed at helping the railway administrations concerned to strengthen their safety culture and develop the monitoring tools required by modern safety management. The train and trolley The CPU calculates the space between the trolley and the train, rate at which the train is roaming, and the distance required for the train to stop. The microcontroller transmit speeding up and deceleration commands to the trolley and/or train to maintain a safe distance between the trolley and a train. If the trolley derail, stop or slow downward due to a hazard on the railway or another difficulty, the CPU generates guidelines to slow down or end the train, as needed, to avoid the train from derailing or colliding with the trolley or a hazard on the railway. The wireless communication can be possible using ZigBee or RF transmitter.
