CSE engineer developed control systems most, if not all of them are proprietary, ranging from very small, with custom made control boards, Arduino, and Raspberry PI systems, to very large SCADA systems with PLC’s & HMI’s, with brands, like SIEMENS, ALAN BRADLY, ABB, LG, and many more.
as a brief let me tell you that While it doesn’t matter "for such simple objective" what type of control board we use, as long as it supports TCP/IP i.e. boards like Arduino will need a SHIELD. I recommend having a local memory to store alarms\events in case of COMM LOSS
Also, the destination with a fixed IP address, whether it is a “website” running a web app, or a private server, this destination will store the received EVENTS\Status from different sites. This process will need to run in the real time, in order for each site to update its status, and for the command center to respond to any change.
As to the presentation of the site alarms/events we can develop a wide range, from desktop apps to web apps, all with elegant easy to understand graphics and controls.
I can do that, and more, but first we will need a meetup to discuss some more details.
I’ll be waiting for you to contact me soon.
Sincerely,
MAHMOUD
