Automatic Railway Gate Control System with Arduino
The document outlines a project by students at the International Islamic University Chittagong to create an automatic railway gate system to improve safety and efficiency at level crossings. The system employs an Arduino-based embedded setup with sensors to detect train arrival and operates gates accordingly, aiming to reduce manual errors and accidents. Key components include an Arduino board, motors, sensors, and light indicators to manage the gate operations automatically.
Introduces the International Islamic University Chittagong, Faculty of Science & Engineering, and lists the contributors: Ahasanul Kalam Akib and team.
Describes the purpose of the project to introduce an automatic railway gate system to enhance safety, reduce manual errors, and minimize gate operation time.
Defines embedded systems as microcontroller-based systems that integrate hardware and software to control machinery and equipment.

The arrivalof train is detected by the sensors placed on either side of the gate at about 1 km from the gates. Once the sensors sense the train, the signal is sent to Arduino. Subsequently, buzzer indication and light signals on either side are provided to the road users indicating the closure of gates. Continue…..

After 2minutes of indicating light signal & buzzer indication, Arduino sent a signal to the motor driver to operate the motor and close the gate. After passing the level crossing the opposite sensors detect the departure of the train. So Arduino get again another signal fr0m the sensors for stopping buzzer & opening the gates. After 1 minutes of stopping buzzer Arduino sent a signal to the motor driver to open the gate.
What is Arduino? Arduino is an open-source prototyping platform based on easy-to-use hardware and software.Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you have to use the Arduino programming language (based onWiring), and the Arduino Software (IDE).

In our projectwe use IR sensor IR Sensors work by using a specific light sensor to detect a select light wavelength in the Infra-Red (IR) spectrum. By using an LED which produces light at the same wavelength as what the sensor is looking for, you can look at the intensity of the received light. When an object is close to the sensor, the light from the LED bounces off the object and into the light sensor. This results in a large jump in the intensity.

As theIR obstacle sensor can sense all objects come in front of it, it might send false signal even if there is any object other than a train. So in real-life, we recommend to use the frequency of the railway lines when a train appears as the signal to control the gate. As we used a toy train in this project, we could not measure the frequency of the lines, so we use the IR obstacle sensors.
