TRAIN COMES AWAY FROM TRACK:
It means that track is not all
problems but train moves out of track. This happens because
Of lack of concentration of the people who works with track. For
example when the nuts and bolts get loosed these sorts of problems will
occur, where property loss will happen to both public and railways but
not that much as the second case.
TRACK DISCONTINUITY:
This happens because of terrorism attack, natural
disaster. There will be damage to track which causes severe damage to
both public and railways which in many cases have led to several deaths.
By keeping such issues in mind, we have come up with an
idea to detect the track discontinuity very sooner before the
train reaches the accident zone.
ABSTRACT:
In our 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.
METHODOLOGY:
Overview:
In our project 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.
Microcontrollers
We use series of the microcontrollers to decide the defect area and the
defect in the track.
Every slave microcontrollers (M1, M2, M3 and so on) are connected
directly to the output of the few sets (S1, S2, S3) and the masters are
connected to many slave microcontrollers. The slave micro controller
decides the defect from processed signal. And the master controller
detects the exact location of the defect area.
