Which microcontroller to choose for very serious tasks? Siemens? And the Model?

Question

Microcontrollers

Hello.

I work in a large taxi company, as a web programmer, I am a little fond of arduino. At work the other day, the manager said that we would do an automatic car wash, while relying as much as possible only on our experience and only occasionally turning to specialists.

Equipment:

1. Sensors for determining the car are still in doubt, if there are options, please write, preferably with approximate prices.

2. Stepper motors, maybe Nema.

3. Electric motors for drying 18.5 kW 2-3 pieces. 1 18.5kw electric motor for the pump.

4. Microcontroller!?

Now the main question is how to manage all this? Accordingly, the word "Microcontroller" immediately flashed through my head, but what kind? I thought in general to do everything on arduino, through relays, contactors and so on, but safety is above all. Now I think, maybe Siemens, if so, which one? After all, you want to save a little, and the task of the microcontroller does not require much (controlling steppers, receiving information from sensors, turning on and off electric motors).

I will be very grateful for the answers of those who know in this area.

Answer 1

All this is certainly great, but ...
"toy" Arduino and industrial Siemens are very different things. Many months of experiments will pass, a lot of dollars spent and a bunch of matyukov listened to from the authorities until you get a more or less sane result.
In reality, everything is solved much easier, find a suitable ready-made solution, come with it to your superiors and explain that you won’t be able to save money “relying only on your experience” (which, as I understand it, neither you nor your boss has in principle). A turnkey solution is not just installed motors, steppers and controllers, it is a balanced hardware and software system
PS. Believe me, in the end, you will spend much more time, resources and money on amateur performance than on a ready-made solution. Either way, look for a new job.

Answer 2

The main thing is the correct circuitry and the catching of curved algorithms. Controller (and other equipment) - no higher than 2..3rd place.

Answer 3

Not necessarily Siemens, there are also Schneider Electric, Allen-Bradley, B&R, Wago.

Answer 4

And then there are GE, Fanuk, Phoenix, Owen... And much more. Simply Siemens:
1) Supplies the ENTIRE range of automation devices (from sensor, controller, network equipment to DCS)
2) Has an extensive network of training centers and technical support throughout Russia
And if something is not in Siemens, then there are partners.
And I would immediately remove the amers - what if they impose sanctions? And where to get iron?
