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.

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.
