This project is a self-propelled railway control gate control using the AT89S52 microcontroller. Using the built-in technology to provide an effective and reliable, closed, feedback management system. The microcontroller allows dynamic speed control. The AT89S52 microcontroller is the heart of the circuit, it manages all functions. PROCORP Technologies is the best place in Hyderabad for mini projects for eee at low cost with effective results.

The main goal of the project is to use a docking gate, for example, to automatically shut down when the train arrives and is open after the train passes. With this designation, the train arrivals are set in any direction. For this purpose, two pairs of infrared transmitters and receivers are used in the project. LCD display provided to illustrate the arrival and departure of the train. One IR TX-RX pair is placed at one end of the railway gate. The second pair is placed at another end of the gate. In each pair, the TX and RX are arranged face to face across the railway track i.e., TX is situated at one side of the track and RX is placed at another side of the track since the RX should continuously get the signal from the transmitter.

Whenever any train is coming on the track, the IR signal will be disturbed due to the interruption of the train. Thus the microcontroller identifies the arrival of the train. Before closing the gate, the microcontroller activates the siren to alert the people who are on the track. After 30 sec, the controller closes the gate by rotating the stepper motor.

The microcontroller needs to know if the train has left the crossing or not to open the gate. For this purpose, the second IR pair is used. This LCD screen sets the train, as the IR signal is disrupted when the train arrives between TX and RX. The micro controller will wait for the last compartment to leave the IR pair and after leaving, the receiver again gets IR signal. Till this time the gate is closed. Now, after the train had left the crossing, the microcontroller will open the gate by rotating the stepper motor.

  1. Excellent post. I was checking continuously this blog and I’m impressed!
    Very useful information particularly the last part :
    ) I care for such information a lot. I was seeking this certain info for a
    long time. Thank you and best of luck.
