ABOUT PROJECT:

The objective of this project is to manage the control

system of railway gate using the microcontroller.

When train arrives at the sensing point alarm is triggered at the railway crossing point so that the people get intimation that gate is going to be closed.

The model of railway track controller is designed by

using 8952 µcontroller to avoid railway accidents.

REQUIREMENTS TO DESIGN EMBEDDED

PROJECT:

SOFTWARE

HARDWARE

SOFTWARE USED:

Keil IDE

Proteus(circuit simulation)

HARDWARE COMPONENTS:

AT 89C52 µcontroller

Vibration sensor

Stepper Motor

L293D motor driver ic

Buzzer

LCD

GENERAL DIAGRAM:

BLOCK DIAGRAM:

AT89C52 µCONTROLLER:

The AT89C52 is a low-power, high-performance CMOS

8-bit µcontroller

8K bytes of Flash programmable and erasable read only

memory (PEROM)

With ram 256 Bytes

1000 Write/Erase cycles which means that it can be erased

and programmed to a maximum of 1000 times

STEPPER MOTOR (L293D):

The stepper tutorial deals with the basic final stage drive

circuitry for stepping motors.

This circuitry is centered on a single issue, switching the

current in each motor winding on and off, and controlling

its direction.

VIBRATION SENSOR:

An accelerometer is a device that measures the vibration

The force caused by vibration or a change in motion

(acceleration) causes the mass to "squeeze" the

piezoelectric material which produces an electrical charge.

It is proportional to the force exerted upon it.

ADVANTAGES:

Accident avoidance

Human safety

Accurate service

With out human interface

CONCLUSION:

The accidents are avoided at places where there is no

human to manage the railway crossing gates.

Here we use the stepper motor to open and close the gates

automatically when it rotates clockwise or anticlockwise

direction to operate the gate automatically.
