SCADA
scada seminar ppt(pantech).pptx (Size: 1.08 MB / Downloads: 47) First of all, Lets see what is a Control System ? A control system, is a system that holds responsible in top of another system (being controlled system) for setting and stabling the system in a predefined state. Nowadays control systems are mostly microprocessor based. (Microcontrollers, PLCs, PC-Based Control systems). What is SCADA? SCADA is “Supervisory Control And Data Acquisition”. Real-time industrial process control systems used to centrally monitor and control remote or local industrial equipment such as motors, valves, pumps, relays, sensors, etc. SCADA is Combination of telemetry and Data Acquisition. SCADA is not just a hardware, neither a software. It’s a concept, it’s a system as a combination of special hardware, software and protocols. SCADA is used to control chemical plant processes, oil and gas pipelines, electrical generation and transmission equipment, manufacturing facilities, water purification and distribution infrastructure, etc. Why SCADA is needed ? The Ability to Remotely collect different plants on different places. The Ability to control process from a distance. The Ability to create logs and reports about system’s current and past state. The Ability to send necessary information to Engineers and operators in real-time using Instant Messaging and SMS. Where SCADA is used ? Electrical generation/distribution, Natural gas distribution Fuel Oil storage & flow Water storage & flow Lighting Heating, cooling, ventilation Fire alarms & suppression Elevators & escalators Gates & doors, alarms Video security cameras Traffic signals Process Line Control SCADA is not a new stuff ! It has been used since the early days of control systems to remotely Control and Monitor current and past state of being controlled system (our plant, factory, etc.) SCADA Hardware Field level instrumentation and control devices Sensing field variables, controlling the process and …. Remote Terminal Units (RTUs) Send control and monitoring data to MTU. (could be a PLC) Master Terminal Unit or MTU (Also called The Master Station) gathering information from RTUs, Monitoring and processing, sending necessary control actions to RTUs. Communication System Last words on SCADA With new trends and technologies of Computer and Electrical Engineering, there are lots of functionalities available, that we can add to our SCADA system. You saw that SCADA covers different fields of Computer Engineering like Computer networking, Control, Programming, Embedded Systems, Operating Systems, Real-time Systems and …. SCADA is a very fast growing technology which is widely used in plants and factories and makes good job opportunities for you in the industry, in engineering field.. |
