In my master's thesis I wanted describe my work from the design point of view of planning a new project - a product that was ordered by a foreign pharmaceutical company and was assigned to me as an electrical project engineer employed at Iskra PIO d.o.o. I described the course of the planning phase we encounter in its life cycle. It is basically a pharmaceutical device, as it was a client from the pharmaceutical industry, whose purpose is to create an environment for efficient, clean and safe weighing of powdered substances. That is why it is also called a weighing cabin or weighing booth. The aim of the master's thesis was to create an autonomous system that is completely independent in its operation, while allowing easy modular expansion of the system according to the needs of the client.
At the beginning of the master's thesis, I presented the device and its concept of operation, as well as planning and coordination with the client and his requirements. Then I presented more details of the selected components of the control, measuring and executive system and the program design and coding of the main core of the program on the programmable logic controller (PLC) and also on the HMI screen. The main part of my master's thesis is about the implementation of regulation, which it occupies; the principle of air flow and air temperature regulation according to the structure of the device and known limitations, coding it and configuration of air flow and temperature regulation from the point of view of the control principle, selection of regulators, response testing and tuning them.
