  5. 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.

  6. FOCUS ON • Train derailment in curves and bends • Collision between trains • Automatic railway gate control

  7. Components (base station) • Micro controller(PIC 16f877a) • Vibration sensor • Servo motors • ZigBee transceiver

  8. Components (Train side) • Micro controller(PIC 16f73) • ZigBee transceiver

  9. BLOCK DIAGRAMS • BASE STATION Power Microcontroller (PIC 16f877a) ZigBee Vibration sensor Servo motor for gate control

  10. TRAIN SIDE Power Microcontroller (PIC 16f73) ZigBee Brake control

  11. ZIGBEE Networking protocol IEEE 802.15.4 suite for high level communication Uses mesh network Based on OSI architecture Data rate-250 Kbits/sec

  12. SERVO MOTOR Rotary actuator Modified form of DC motor Precise control of angular position Based on PWM switching

  13. MICROCONTROLLER • PIC16f877a(Base station) • 8-bit microcontroller. • 40 or 44 pin package. • 256 bytes of EEPROM data memory. • Interfaced with the input sensing devices.

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

  15. Vibration sensor Uses piezoelectric effect Vibration indicates the arrival or departure of train. Sense the position of train at 1 to 3km away.

  16. types Continued…. • Mini sense 100-vertical • Mini sense 100-horizontal The sensor used here is mini sense 100 vertical

  17. Continued…. Mini sense 100 vertical • High sensitivity • Good frequency response • Excellent linearity • Shielded construction • Analog output • With stands high shock

  18. 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 Power supply will cutoff Collision can avoided

  19. TIP 122 1. Base 2.Collector 3.Emitter silicon Epitaxial-Base NPN power transistors switching applications. High power transistor Power dissipation - 2w DC collector current - 5v No of pins - 3

  20. 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.

  21. 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

  22. Continued…. Automatic railway gate control START CHECK ANY DATA PRESENT IF DATA RXED FROM TRAIN NO YES GATE CLOSED

  23. OVER ALL WORKING • The proposed model makes use of ZigBee protocol as a medium of transferring information

  24. 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

  25. 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.
