These systems have existed in various forms since the 1960s, and since the 1990s they have experienced a great expansion with the appearance of faster and more efficient computer and microcontroller devices. They can be used for simple monitoring (eg temperature, air humidity, pressure) as well as for complex monitoring and management (eg production processes in factories or regulation of rail and road traffic).
A SCADA system typically consists of:
* converters and actuators
* RTU (eng. Remote Terminal Unit)
* communication networks
* central stations
Transducers and actuators represent the beginning of the chain. They are electrically or mechanically linked to the process we are observing. The task of the transducers is to monitor the values of pressure, flow, temperature, speed... and to transmit information about the current state of the measured quantity to the RTU in analog or digital form. The actuators receive information from the RTU and e.g. they close or open the valves.
In case of errors during the night intervals, our employees are trained to eliminate the errors and return the system to normal operation.
