2. 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.

3. REQUIREMENTS TO DESIGN EMBEDDED
PROJECT:
 SOFTWARE
 HARDWARE
SOFTWARE USED:
 Keil IDE
 Proteus(circuit simulation)

4. HARDWARE COMPONENTS:
 AT 89C52 µcontroller
 Vibration sensor
 Stepper Motor
 L293D motor driver ic
 Buzzer
 LCD

5. GENERAL DIAGRAM:

6. BLOCK DIAGRAM:

7. 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

8. 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.

9. 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.

10. ADVANTAGES:
 Accident avoidance
 Human safety
 Accurate service
 With out human interface

11. 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.
