In this project we control railway crossing system automatically. In this project we use total three control systems.
-
Train Detection
-
Both side Barrier of Train
-
PIR security For person or vehicle in between Crossing
-
Station Monitoring

Auto open and close railway gate . this provision is very important version also. By using this technique we not only save the valuable life of human being but provide a smart modification in railway automation. Opening and closing of this door is provide by the stepper motor logic. Here we use stepper motor for opening and closing the door automatically. When we use this option then we use magnetic reed sensor for this purpose. By using this technique when train sense the magnetic sensor then railway gate is automatic open and automatic closed. For opening and closing the door we use two reed sensor. In this project we will use two IR sensor for train detection. So that crossing should open and close according to train only.

Two barriers- there will be barrier motors on both side of crossing. Normally students make project with barrier on one side only. In this project we will make barrier DC geared motors on both side of Crossing. We will use Dc geared motors On both side of crossing. We will use H bridge circuit for controlling motors. We will use 12v 100 RPM motors. We can use transistors or L293D ic for making h-bridge circuit.

We will Use PIR sensor for person detection in between the crossing during train detection. PIR are proximity infrared sensors. PIR should work only when any Train and person both detected. Other wise it should not work. PIR give High output when it works. It will give pulse to Transistor . Transistor will give low high pulse to Microcontroller. When MCU will detect pulse then it will give pulse to buzzer circuit. We will use transistorized circuit to drive buzzer.
