How can one do a good job in the design of automated instruments in a design institute?

For a design project, it is first necessary to understand the various instruments used in different stages, and to select those that are suitable for the specific working conditions on site. Since the technical parameters of instruments of the same type are generally similar, it is important to have a thorough understanding of the differences between these products, in order to determine the technical parameters that are most appropriate for the project site and use them in the design of the instruments!!!

2# We’re in different places. It seems like you have quite a bit of experience; please share your knowledge with me!

It is recommended to spend a year at the construction site and be fully involved in the commissioning process of a project; if one stays at the design institute the whole time, it will be very difficult

1# pily: I’m facing similar difficulties to lz, and my foundation in automated instrumentation and process control is weak – I didn’t study it seriously before. For now, all that can be done is to learn how to identify instruments and how to select the right models; it’s still too early for actual design work. Could you guys recommend some books to read? Preferably in PDF format. My email address is endymion27@sina.com. Thank you!

Design work involves a lengthy process, and I think it’s not quite appropriate to start learning about *selection right from the beginning. Selection is a very complex task; by the time you think you’ve mastered it, you still don’t know where the real challenges lie. It is best to develop skills, master the software used in the work platform, and understand the relationships between various roles within a project. Secondly, it is to learn the standard construction drawing specifications and apply them in projects. Once again, study carefully on-site and observe the differences between the standard drawings and the actual site conditions, as well as any omissions in one’s own designs, making sure to take notes and draw conclusions. Finally, there is selection, solution design, and so on. This should be something that happens in 3 to 5 years. Indeed, some people say they learned it after 2 years; congratulations, you are an expert – a future engineering master.

If one has substantial practical experience, then designing should come naturally. It’s impossible to expect to be able to create good designs right after graduating from school. Designs made by people without practical experience cannot stand up to scrutiny on construction sites; they are full of mistakes and flaws – there are too many things that seem reasonable on paper but don’t work in practice. These days, people tend to aspire to be \"white-collar\" workers and are unwilling to learn and gain experience at the grassroots level, which actually does no good at all for their design work. Many installation and construction techniques are not available in books. I think spending more time learning and gaining experience at the grassroots level will lead to further improvement.

Gain experience in the project. During this period, it is necessary to read the design manuals and relevant specifications frequently. In fact, many standards are really useful. Creating good instrument design indeed takes time.

It’s not easy to master the design of automated instruments without 3 to 5 years of experience – I know this well. First of all, one needs to study the regulations and standards; it’s best to do so in conjunction with actual projects. Simply looking at those regulations and standards is likely to result in a failure to understand their meaning. Secondly, getting started with instrument design is relatively quick – it may take just half a year to learn how to create tables and make selections based on certain criteria. At this stage, one needs to ask countless questions, to go to the site to understand the situation regarding the instruments, and to figure out the origin and rationale behind each element in the tables. Lastly, instruments evolve rapidly – from electric instruments to pneumatic ones, from separate components to integrated systems nowadays. One shouldn’t stick to old ways of thinking. I now realize that I didn’t pay enough attention to the basics back then; there are still many simple questions that need to be asked frequently. According to my mentor, during the first three years of work, no one will laugh at you if you ask questions, but after five years, people will start to doubt whether you have any experience in instrument design at all

I’ve gained some work experience; I’ve only been working for two years myself, so I can relate to it

Go to the site more often, and also take into account the operating conditions when selecting instruments and meters
