A supervisory system is a type of system that oversees and monitors the operation of other systems or processes. It typically involves the use of sensors, controllers, and communication devices to collect data, analyze performance, and make real-time decisions to ensure the efficient and effective operation of the system being supervised. Supervisory systems are commonly used in industrial settings, such as manufacturing plants, power plants, and infrastructure systems, to monitor and control various processes and equipment. They help to optimize performance, minimize downtime, and improve overall productivity. These systems often include features such as data logging, alarm notifications, remote access, and automated control functions. They are typically customizable and can be tailored to suit the specific needs and requirements of the system or process being monitored. Overall, supervisory systems play a crucial role in enhancing the operational efficiency, safety, and reliability of complex systems and processes.
