Drawbacks of traditional instrumentation
These systems are fixed, (mobile monitoring is
These systems can do only one task (single
sensor). Hence, need different systems for
different purpose of detection.
They bank on portable display which is
attached with the system.
They cannot be accessed from remote locations.
To overcome the problems of traditional
surveillance system a Virtual
Instrumentation based Surveillance system
is developed through which we can monitor
and control the hazardous and inaccessible
places to humans.
What is Virtual Instrumentation?
Virtual instrumentation is the use of customizable
software and modular measurement hardware to
create user-defined measurement systems,
called virtual instruments.
Virtual Instrumentation based Surveillance system
The proposed multi-sensory security system is designed to
have 4 sensors, it is provided with 2 wheels to provide continuous
unmanned monitoring of
o Gas leakages
o Sudden changes of temperature
o Obstacle avoidance
o Smoke ejection.
And notifying through a wireless ZIGBEE module on a LABVIEW
The GENIE system offers flow chart microcontroller
programming and simulation as well as full integration
with circuit wizard.
GENIE Microcontrollers can be programmed using
flowcharts. Flowcharts show the steps that will be
followed by microcontroller when one’s program is
running. Flowcharts are drawn by selecting particular
commands and then linking them together.
GENIE LAB STUDIO
Genie design studio has been used to program microcontroller for obstacle avoidance and the
programmed flow chart for obstacle avoidance is shown below in next slide.
Lab VIEW is an integral part of virtual instrumentation
because it provides an easy-to-use application development
environment designed specifically with the needs of
engineers and scientists in mind.
Features of Lab View:-
Operate the instrumentation program
Control selected hardware
Analyse acquired data
ZIGBEE WIRELESS MODULES
ZigBee is the name of a specification for a suite of high
level communication protocols using small, low power,
low data rate digital radios based on the IEE 802.15.4
standard for wireless personal area network (WPANs),
such as wireless headphones connecting with cell
phones via short range radio. The technology is intended
to be simpler and cheaper than other WPANs, such as
Bluetooth. ZigBee is targeted at radio-frequency (RF)
applications which require a low data rate, long battery
life and secure networking.
The virtual instrumentation based surveillance
system to monitor the changes in surrounding,
helping in preventing the disaster of fire, gas and
smoke out breaks by notifying us the leak. The
results illustrate that the proposed Virtual
Instrumentation based intelligent Surveillance
system provide continuous unmanned monitoring
of Gas leakages, sudden changes of temperature,
obstacle avoidance etc.
