  4. 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.

  5. Causes for railway accidents Human error. Track problems or adverse weather conditions. Derailment in curves and bends. Mis-signaling due to fog or mist. Collision between trains

  6. Existing system Oral communication through telephonic and telegraphic conversations. LASER Proximity Detector Use of satellites for communication. No combined solution for collision avoidance and railway gate control

  7. FOCUS ON • Collision between trains • Automatic railway gate control

  8. BLOCK DIAGRAM BASE STATION SIDE Motor driver ATMEGA16 IR sensor 1 IR sensor 2 IR sensor 3 IR sensor 4 Motor 1 Motor 2

  9. BLOCK DIAGRAMS • Train side ATMEGA16 Trigger Ultra sonic sensor Motor driver Echo LCD Display Motor 1 Motor 2

  10. Components IR Sensor Ultra sonic sensor ATmega16 DC motor Motor driver LCD

  11. IR SENSOR Used for gate control. Works based on detection mechanism. IR led is used here for detection. Very compact (small size) High performance Low cost

  12. WORKING PRINCIPLE OF IR SENSOR

  13. ULTRA SONIC SENSOR For avoiding collision between train Generate high frequency sound waves TR 40-12 ultra sonic sensor used here 20 mA power consumption Simple pulse in/pulse out communication

  14. WORKING PRINCIPLE OF ULTRA SONIC SENSOR

  15. MICROCONTROLLER The micro controller used here is ATMEGA16 Set of digital logic circuits integrated on a single chip. Micro controller is for entire control. Examples:8051,89c51,PIC,motorola etc

  16. ATMEGA16 Used for entire control 40 pin DIP package Low power consumption RISC architecture 512 bytes of EEPROM

  17. PIN DIAGRAM PORT A PORT B PORT D PORT C

  18. DC MOTOR Runs on direct current Operable directly from rechargeable batteries Cost effective rotary motion control Fully reversible Consists of stator and rotor Stator –stationary part rotor-rotating with respect to the stator

  19. MAIN PARTS OF DC MOTOR

  20. MOTOR DRIVER(L293D) Quadruple high current half-H driver. 4.5 to 36 voltage range High noise immunity inputs Thermal shut down Contain two in built H bridge driver circuits

  21. PIN DIAGRAM OF L293D

  22. LCD Liquid crystal display Uses the light modulating properties of liquid crystals Liquid crystals do not emit light directly more energy efficient Work with almost any µc low electrical power consumption

  23. CIRCUIT DIAGRAM

  24. Collision between trains UV sensor placed in front of the train Continuously check the presence of train Sensor will emit the TRIGGER signal continuously Any train in opposite direction ,TRIGGER signal reflected back as the ECHO signal Train will stop automatically

  25. Automatic railway gate control • Sensor sense presence of train 3 km away. • Output given to µc • µc give instruction to close the gate • Gate is closed automatically using DC motor. • Gate is opened after the train is passing

  26. SOFTWARE USED PROTEUS SIMULATION SOFTWARE IAR EMBEDDED WORK BENCH ORCAD

  27. Result and Discussion • The sensors sense the input and sends to the microcontroller, where it responds • 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 in coherence would help to reduce the train collisions.

  28. 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 & 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.
