Hello poster, I can tell you clearly that there are indeed many industries that are engaged in automation. Not only that, but there are many. There are many types of automation and it is very complicated. For example, the number of domestically registered automation trademarks in 2021 exceeded 20,000. Moreover, the threshold for automation is very low now, but anything related to industry can be said to be in the automation industry. If the poster wants to know about the brands of automation, I can tell you slowly:

The more famous brands in PLC automation are: Omron, Panasonic Electric Works, Mitsubishi, Fuji, Siemens, etc., which are well-known at home and abroad. They are all quite famous large companies.

The domestic Lemanson Automation Company is relatively famous in the automation of fluid and pipeline engineering. It is an old company with 12 years of experience and rich experience. A friend of mine works with them. Signed a long-term cooperation contract. I personally recommend it, it's quite formal, and overall it's pretty passable.

Of course I need to explain to the poster that the companies I have listed here are all relatively well-known companies. There are other less well-known companies that I will not list here. There are quite a lot of automation categories. It is quite detailed, so I may have omitted some things here, and you are welcome to add to them. I have said so much, and I hope to get recognition and praise from the poster.
