SCADA
systems, acronym for Supervisory Control and Data Acquisition systems
are supervisory systems that have made automated tasks more reliable
and efficient without having need of human to intervene or handle any
stage of process.
Thus, SCADA systems are also known as closed loop systems as they
operate of their own and response to change in parameter value/ state
beyond permissible values. Also, there is always a possibility of human
intervention as per the need that provides flexibility to SCADA
systems. Due to high range of flexibility, reliability and efficiency
SCADA systems have found their applications in control systems
(electricity control systems, water sewerage systems), radio
transmissions (long distance Scada GSM).
Even daily routine equipments have not left untouched by this
tremendous technology and many SCADA compatible equipments like water
metering pumps have flooded markets.

SCADA stands for Supervisory Control and Data Acquisition. SCADA can be
thought of as a system which is designed to collect data from the
sensors located in remote locations, such as various areas of a plant,
factory or at any other remote location and then sending the data
collected to a main computer which controls and manages the data.
SCADA has finds its application in wide range of industries from
electric power, water management systems, environmental control
systems, mass transportation or manufacturing systems.
A SCADA system can be divided into following parts: Signal hardware
(for both output as well as input), controllers, user interface (also
known as HMI), networks, and software along with communication
equipment. In general, SCADA means entire system with the common goal
to collect, manage and control the data. |

If
the project encompasses large area to be surveyed and human
surveillance in not possible in such case, then one needs long distance
SACDA radio networks to be employed for sending the data collected from
remote sensors to central unit.
When area under surveillance is hundreds of kilometres such as in case
of petroleum pipeline, the only feasible solution is long distance
Scada GSM. Most important requisite for long range Scada GSMs
is ability to transmit the data to long distance.
For such purposes, repeaters are used as line of sight is limited to 5
miles. Repeaters are radio transmitters which act as boosters for
signals as signals tend to get weak after travelling certain amount of
distance. Thus repeaters boost the attenuated signals and again
transmit them to next repeater/ central system.
