Supervisory Control and Data Acquisition (SCADA)
Published in Chanchal Dey, Sunit Kumar Sen, Industrial Automation Technologies, 2020
SCADA is a system used for remote monitoring and control of coded data using communication channels – both wired and wireless. Thus the status of the remote plants and machineries can be displayed/recorded at a central location. SCADA systems are highly distributed where centralized data acquisition and control are highly critical for proper plant operations. Oil and gas pipelines, railway transportation network, water distribution systems, power generation, and distribution are some of the areas in which SCADA is applied for data acquisition and control. The centralized control center monitors and controls field sites spread over highly dispersed locations via communication networks. Based on the information received, either automated or operator initiated supervisory commands can be put on the communication channel for controlling remote field devices.

In summary, remote monitoring and control telemetry systems can be expensive. However, there are some benefits if the system is properly planned, designed, and integrated into the standard operating procedures and the business system of an organization. In the last few years, engineers of the RTSs have changed the way they design and fabricate systems. Through the use of ultra-fast computers with large memory bases and standardization of hardware, various systems can be integrated with very little effort and most times with off-the-shelf software. Remote telemetry systems can collect information and monitor water quality continuously (down to sub-millisecond). Using the RTS a central operator can monitor, respond, and adjust water treatment performance in a matter of seconds. Troubleshooting can be done remotely, reducing downtime and increasing the repair efficiency. Automated “smart systems” can identify operating trends and adjust operating parameters to accommodate most trends. Many of the smart systems can remedy problems before technicians are aware that any problematic situation exists within the treatment system. Remote monitoring and control of individual and community treatment systems are now becoming a practical option for the small communities. Remotely monitoring treatment system operating parameters could provide an attractive alternative to fixed sampling and O&M schedules thus permitting customized customer service of the treatment system device by a centralized operator.

The SNs are usually the first SGNs to implement, since they support the most critical applications realized in the SG. Substation automation services include the remote monitoring and control of SCADA systems, phase measurement units (PMUs), remote terminal units (RTUs), and intelligent electronic devices (IEDs). The common characteristic of all these devices is that they generate SG information that needs to be collected via the backhaul networks, that is, the SN, in real-time synchronized mode of operation. Since synchronization is a critical issue, global positioning system (GPS) enabling is usually proposed in the literature [24]. As to PLC transmission, both BB-PLC and NB-PLC seem appropriate to serve SN communications, taking into account that the former option supports low whereas the latter supports high transmission rates. Other options may include wireless and optical media [43].
The potential mental health effects of remote control in an autonomous maritime world

However, consider the situation were a local crew or are not available to receive and give commands, a remote situation room would need to be used (Porathe, Prison, and Man 2014). Thus, a suite of technology is required to support all these human-autonomous actions, at all levels of autonomy. This suite includes large sensor or IoT networks, which are designed to improve remote monitoring and control for both machine learning AI algorithms and human supervisors.
