SCADA (supervisory control and data acquisition) generally refers to industrial control systems (ICS): computer systems that monitor and control industrial, infrastructure, or facility-based processes, as described below:
Industrial processes include those of manufacturing, production, power generation, fabrication, and refining, and may run in continuous, batch, repetitive, or discrete modes.
Infrastructure processes may be public or private, and include water treatment and distribution, wastewater collection and treatment, oil and gas pipelines, electrical power transmission and distribution, wind farms, civil defense siren systems, and large communication systems.
Facility processes occur both in public facilities and private ones, including buildings, airports, ships, and space stations. They monitor and control HVAC, access, and energy consumption.
The term SCADA usually refers to centralized systems which monitor and control entire sites, or complexes of systems spread out over large areas (anything from an industrial plant to a nation). Most control actions are performed automatically by RTUs or by PLCs or powerful microcontrollers. Here in this project advanced system called GSM to this SCADA monitoring and controlling is done in the form of SMS to authorize mobile.
We will design a RTU comprising a microcontroller interfaced with a Temperature Sensor for temperature and a LCD for display. ADC0804 is connected to a MICROCONTROLLER. In this project mainly supervisory control and data acquisition of temperature and controlling the parameters like heater and cooler .to control the temperature.
