Abstract:
Our
project “railway track tracer” automatically traces the track discontinuity
several kilometers ahead and alarms near by station and the Train about the
track discontinuity.
In
this project, we use series of sensors
which senses the continuity of the track by sensing the vibration in the track.
When a train passes its vibration in track it travels with very
great velocity than the train velocity so that it can be detected several
kilometers ahead before the train. we use a series of sensors which detect the
vibrations from the track. The output of the sensors are fed to the switching
and rectifying circuit which processes the sensed signal ready to feed for the microcontroller.
The processed signals are first fed to the opto couplers, output of which is
fed to the microcontroller. The microcontroller decides from the received
signal about the track discontinuity, and when a discontinuity is found in the
track.
