| Summary: | Bridge
scour is an
erosion which remove
s
stream bed or bank
material from bridge foundation
due to flowing
of
water.
Too much bridge scour is risky
for the bridge foundation
and cause
s
sudden bridge to
collapse without any warning. It implements significant impacts on the traveling public safety
as well as the
economy of the country
. A number
of parameters are associated with scour, thus different types of sensors are
required to measur
e the individual affecting factor. A complex and expensive data logging from sensor and
electronic communication
system
s are used to
monitor
the
br
idge scour in real
-
time to
ensure the integrity
of
bridge
structure. A high frequency band (13.56MHz) radio f
requenc
y identification (RFID) system ha
s
been
proposed and that
has been
validated by simulation
using PSpice software
for
the
direct scour monitoring
scheme
, which is simple and low
-
cost
. A number
of passive RFID tag
s
have been
piled surrounding the brid
ge
foundation
which
is continuously detected
by the FRID reader
. The erosion of the river bed carries out the RFID
tag from nearby the bridge structure
. A
s a result
,
the RFID reader
can
directly detect the absence of the tag
s
as
well as the amount of the s
couring.
Since,
the
design
structure of the RFID system
is simple
, it is highly robust
and easy to implement. The system can easily
be
implement
ed
with an existing bridge structure and a wireless
telemetry can be used to send the real
-
time data from the pr
oposed system to a desktop computer in the
monitoring lab |
