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.

TRAIN SIDE

MICROCONTROLLER

• 8-bit microcontroller.

• 40 or 44 pin package.

• 256 bytes of EEPROM data memory.

• Interfaced with the input sensing devices.

PIC16f877a (Base station)

MICROCONTROLLER

• 256 bytes EEPROM.

• 8 KB of flash memory.

• 28 pin package.

• Placed inside the train.

PIC16f73 (TRAIN SIDE)

Vibration sensor

Uses piezoelectric effect

Vibration indicates the arrival or departure of train.

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

ZIGBEE

Networking protocol

IEEE 802.15.4

suite for high level communication

Uses mesh network

Based on OSI architecture

Data rate-250 Kbits/sec

Rotary actuator

Modified form of DC motor

Precise control of angular position

SERVO MOTOR

Train derailment in curves and bends

Sensor is placed on the track.

Sensor output given to µc

µc sends pulse to the ZigBee receiver

Receiver get signal with out loss means , track is good

Receiver doesn’t get signal means µc sends instruction to stop the train

Collision between trains

Using vibration, the sensors identify the position of trains.

Distance & position monitored by µc.

µc responds and gives command to braking system of train using Zigbee.

Stop the trains to avoid collision.

OVER ALL WORKING

The proposed model makes use of ZigBee protocol as a medium of transferring information

TRAIN COLLISION AVOIDANCE

Result and Discussion

The sensors sense the input and sends to the microcontroller, where it responds and givescommand to the particular component with predefined algorithm. The time parameters are crucialwhich can be easily changed and modified using Micro-controllers. Thus, this device would work incoherence would help to reduce the train collisions.

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.
