INTRODUCTION

In the rapidly flourishing country like ours, accidents in rail road railings are increasing day by day.

The train accidents cause severe damage to life and property

This project deals with one of the efficient method to avoid train accidents.

  • PIC16f73(TRAIN SIDE)
  • 256 bytes EEPROM.
  • 8 KB of flash memory.
  • 28 pin package.
  • Placed inside the train.
vibration sensor
Vibration sensor

Uses piezoelectric effect

Vibration indicates the arrival or departure of train.

Sense the position of train at 1 to 3km away.

Mini sense 100 vertical

  • High sensitivity
  • Good frequency response
  • Excellent linearity
  • Shielded construction
  • Analog output
  • With stands high shock
collision between trains
Collision between trains

Sensor sense the vibration

More than one sensor show high value

µc sends signal to µc in train side

Using zigbee transceiver section

Train derailment in curves and bends

  • Sensor sense continuously.
  • µc doesn’t get value.
  • µc sends signal to µc in train side
  • Using zigbee transceiver section
  • Power supply will cutoff
  • Train will be stopped.

Automatic railway gate control

  • Sensor sense vibration 3 km away.
  • Output given to µc
  • µc give instruction to close the gate
  • Gate is closed automatically using servomotor.
  • Gate is opened after the train is passing

Result and Discussion

The sensors sense the input and sends to the microcontroller, where it

responds and gives

command to the particular component with predefined algorithm.

The time parameters are crucial

which can be easily changed and modified using Micro-controllers.

Thus, this device would work in

coherence would help to reduce the train collisions.

Train safety

conclusion
CONCLUSION

In this project, an anti-collision system for trains have been designed, simulated and tested.

The simulation has been done using proteus electronic simulation package

Train collisions , de railing & rail road accidents are avoided.

Hence it is expected that, major train mishaps can be prevented and human life saved if this system is implemented.
