Integrated Information Management and Systems


SCADA (Supervisory Control and Data Acquisition) systems are used to control dispersed assets where centralized data acquisition is as important as control. These systems are used in distribution systems such as water distribution and waste water collection systems, oil and natural gas pipelines, electrical utility transmission and distribution systems.



Centralized SCADA centres provide a dashboard view of the entire assets and enable real time control & monitoring of the facilities irrespective of the distances involved and historical archiving of data for future data analysis.


For example Centralized Water SCADA centres integrate the data from raw water sources, water treatment plants, water pumping stations, pipe line distribution,storage locations and flow data up to end consumers ,leakage detection data ,to provide a comprehensive view and control in real time of the water assets and management to the water utility authority.


Design involves selection of appropriate field instrumentation (Flow, Level, Pressure, Analytical Instrumentation & Analyzers), PLC based SCADA Systems/Distributed Control Systems (DCS) and the communication architecture to achieve the desired function.


Supervisory Control and Data Acquisition (SCADA) systems are designed to collect field information, transfer the information to a central computer facility, and display the information to the operator graphically or textually, thereby allowing the operator to monitor and control an entire system from a centralized location-centralized SCADA centres in real time. Based on the sophistication and setup of the individual system, control of any individual system, operation, or task can be automated, or it can be performed by operator commands.


The control center collects and logs information gathered by the field sites, displays information to the Human-Machine Interface (HMI), and may generate actions based upon detected events.


The control center is also responsible for centralized alarming, trend analysis, and reporting. The field site performs local control of actuators and monitor sensors.


Standard and proprietary communication protocols running over serial communications are used to transport information between the control center and field sites using telemetry techniques such as telephone line, cable, fiber, and radio frequency such as GSM,GPRS, microwave and satellite.
