Automatic Railway Gate Controller using Bollard with Track Security and Anti-Collision System

Railway gates are generally opened or closed manually by a gate keeper. But some railway crossings are totally unmanned and many railway accidents occur at these level crossings. Through this project we have tried to automate the process of railway gate control with the help of IR sensors, keeping in mind the complete safety of human life. Reflective type IR sensors, where the IR transmitter and receiver are placed side by side, are used. When there is no obstacle in front of the sensor, the IR rays travel undetected. If there is an obstacle, the IR Rays gets reflected from the surface of the obstacle and are incident on the IR Receiver. This setup can be used to detect an object like a train and in turn can be used to control the motor with the help of microcontroller. Some additional features include track security, to detect if there is a crack in the track, bollards at the gate to stop any object from passing after the gate closes, anti-collision to prevent loss of life by getting hit by the train and an LCD display and a buzzer for alerting in the condition of an accident.
