15. 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

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 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

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.
