Train Accident Precaution and Station Information System

Abstract

The Indian Railways is one of the largest railway networks in the world. The increased number of trains has
resulted in increased amount of train accidents. Most of the accidents are due to the collision of trains. Because of the
advancement and development in the field of embedded systems many systems have been evolved to prevent the
accidents. Developing a system in a low cost with a good efficiency is a great challenge. This paper talks about a system
which overcomes these challenges. The aim of the proposed system is to prevent the train from accidents and provide
the information to the nearby station. It is based on the automatic safety control used in trains. This system makes use
of the Li-Fi and ultrasonic sensor on the Arduino platform. This design consists of an ultrasonic sensor, Arduino
processor, and a Li-Fi circuit (transmitter and receiver). Ultrasonic is used to measure the distance between the
obstacle and the Arduino processes that data to get decisions accordingly. The data transmission between the train and
the sub-station is done using Li-Fi transmitter and a receiver circuit [9]. The ultrasonic sensor will be mounted on
front of the train to sense the obstacle. This information is then given to the nearby station via the Li – Fi transmitter.
The Li – Fi receiver at the nearby station receives the information. In this paper, a system which can detect and thus
avoid collision between trains and prevent the accidents is proposed and is studied.
