Automatic Railway Gate Controlling and Smart System of Railway Gate Crossing using IoT

The main objective of this paper to propose the smart system of controlling the railway gate automatically to avoid the accident while crossing the railway gate as well as smart way of railway gate crossing using the mobile application. In this system we are using the Internet of Thing (IoT). IoT is a network of interconnected devices which are connected with sensors. For IoT device can communicate with no human interrupton. By implementing these, it will provide control of railway gate to the device which operates the railway gate. It reduces the time, gatekeeper carelessness for operating the gate close and open than the gatekeeper. So this system is useful for reduction of the accident at level crossing. In addition to this, one more additional feature is implemented for the driver’s convenience who can use for the level crossing. Here, driver needs to install the mobile application in their mobile by which they can check the railway gate is open or close. The Ultrasonic sensor detect the train is coming or not and with help of NodeMCU send to the Google Firebase and Firebase will send the same information to NodeMCU which is located at level crossing and close the gate with the help of Servo Motor, and when the train departure from the another side Ultrasonic Sensor it will again send data to Google Firebase and Firebase again give command to NodeMCU to open the gate which is located at level crossing. This is cost effective, real time and time saving automatic system.
