Railway is the most popular and friendly transportation system of the largest part of the cities in the world. Train is widely used for comfortable and safe journey in a reasonable fare. People from different professions can effort it. Almost 10,000 billion freight tonne-Kilo-meters and more than 5 billion Passengers of rail transport have been travelled around the world per years. The railway transportation system plays an important role for business as well as for leniency and safe travelling in modern life. One more thing, passengers aboard the train before the train stops. In such a situation, the passengers risk their lives.     The project aims in designing a train accident avoiding system using Arduino. The proposed system is an enhanced technique for monitoring the object which uses Arduino microcontroller, ultrasonic sensor, and radar module. The radar will get the distance from the object and ultrasonic sensor will ensure to avoid the accidents that may occur by the clash between the train and objects.   The controlling device of the whole system is a Microcontroller. Ultrasonic sensor, servo motor long with barrier gates are interfaced to the Microcontroller. When the ultrasonic sensor detects the train, microcontroller will close the barrier gates to let the person in. To achieving the task, the controller is loaded with a program written using Embedded ‘C’ language.  

The main objectives of the project are:

 

1. Automatic train arrival/despatcher detection using ultrasonic sensor.
2. Automatic barrier gates open/close.

   

The major building blocks of the project are:

 

1. Regulated Power Supply.
2. PIC Microcontroller.
3. Ultrasonic sensor.
4. Servo motor through barrier gates.
5. Crystal oscillator.
6. Reset.
7. LED indicators.

 

Software’s used:

   

1. PIC-C compiler for Embedded C programming.
2. PIC kit 2 programmer for dumping code into Micro controller.
3. Express SCH for Circuit design.
