SCADA (SUPERVISORY CONTROL & DATA ACQUISITION) For Remote Industry Based On 8051 Microcontroller
SCADAsystems are mostly
used in industry for supervisory control and data acquisition of industrial
process application as they are simple, robust, and reliable in use. This
process can be industrial and infrastructural, with the further use of
electronic and the SCADA systems are used in large scale industrial plant
automation where monitoring andcontrolling all the process at a time manually
is not possible. It provides an efficient tool to monitor and control equipment
in manufacturing processes
The
main goal of the supervisory control of data acquisition for remote industry is
to process the real-time data obtaining under supervisory control for a
large-scale remote industrial environment.
Block diagram:
Here temperature
sensors are interfaced to the 8051 micro-controller Information gathered from the temperature sensors are always sent to the
microcontroller which is thus associated with a PC.On the front end,
“DAQ System” (software) loaded in the computer which takes these values and
displays them on its front panel, and also logs then in the database. We can
set parameters like set point, low limit and high limits on the computer
screen.
When temperature of a
sensor goes above the set point the micro-controller sends a command to the
corresponding relay. The heaters are connected through relay contacts
(corresponding to their sensors) are turned OFF are available for generating an
AV alarm on the PC in the event of system failure. Hence, processes at
hazardous area can be controlled accurately and better safety using Supervisory
Control and Data Acquisition. Adapting such a technology will save both money
and time.
