Idea 1
In this project the vibration sensing element is
placed on the track. It's fancied with peizo electrical plate. It converts the
mechanical vibration in to electrical signal. The vibration sensing element
output is given to electronic equipment so as to amplify that electrical
signal. At that point the amplified signal is given to microcontroller.
Furthermore, that they have transmitter and receiver each square measure
connected with cables.
These square measure closely connected with track, if
the track is cut, this cable also will cut. In actual time they need this
vibration sensing element, transmitter and receiver in track for each two
hundred meters. On the other hand they will extend this distance victimization
amplifiers. Once the train comes on the track, the vibration sensing element
detects the train's vibration and sends a coffee pulse to the microcontroller.
At whatever point the controller detects a coffee
pulse from sensing element, it'll send a checking data to receiver from the
transmitter. On the off chance that the receiver gets the signal while not loss
means that, the receiver send a high pulse to controller then it establish the
track is beautiful. On the off chance that the receiver did not get the signal
means that the controller can sends a warning sms to the receiver mobile, that
is in train, through the transmitter mobile, that is interfaced with
microcontroller.
The rs232 is employed for communicate the controller and
mobile. In this manner the accident is avoided. Once the staff square measure
reaching to work on the track means that they're going to press key, that is
interfaced with microcontroller. At that point the controller can send an alert
sms to the receiver mobile. Prior to this they have to program the
microcontroller for this application.
Idea 2
The venture is intended to recognize a split,
assuming any, on the railroad track and caution the individual railroad office.
This is to keep away from rail mishaps by utilizing most recent correspondence
advancements. In this venture gsm correspondence conventions are utilized to
pass on the message of break identification through sms.
This venture utilizes a microcontroller from 8051
family. The essential target of this venture is to recognize the break in the
railroad track and caution the close-by station through successful and very
solid correspondence mode. To exhibit this venture, two rails framing the part
of a track are made utilizing a couple of wire which is associated with a
separable jumper in the middle of every wire/track. Expelling the separable
jumper makes a blame in the separate track; else it is by and large shorted by
the jumper wire to recreate solid track condition.
Evacuating the jumpers bring about driving
transistors conveying an alternate rationale to the controller. The program
from that point assumes control to send a sms through gsm modem interfaced
through a level shifter ic to the microcontroller. A lcd is additionally
interfaced to the mc to show the status of gsm and track condition. Hence the
proposed model is intended to perceive the breaks in the railroad tracks and
gives moment data to the concerned railroad powers.
The power supply comprises of a stage down
transformer 230/12v, which ventures down the voltage to 12v ac. This is changed
over to dc utilizing a bridge rectifier. The swells are expelled utilizing a
capacitive channel and it is then directed to +5v utilizing a voltage
controller 7805 which is required for the operation of the microcontroller and
different segments.
