20.500.12556/RUL-106057 Obnova krmiljenja ekstruderja Revamping of the control system for the extrusion process Diplomsko delo opisuje delovanje in program ekstruderja, katerega krmilni sistem se je prenavljal v sklopu projekta v podjetju INEA. Ekstruder je stroj, ki združuje tako sekvenčne kot regulacijske procese. Rezultat teh procesov je obdelava plastike v produkt, ki je v tem primeru neprekinjen trak variabilnih dimenzij. Podrobneje so opisani deli programa za katere sem bil osebno zadolžen. Sam program se deli na dva dela: program programirljivega logičnega krmilnika ter program vmesnika človek-stroj. Oba sta napisana s programskim orodjem Siemens TIA Portal v14. Prvi del naloge je posvečen opisu stroja, sestavnih naprav in sekvence zagona. Nato sledi še opis samega programa in njegove strukture, ki je v večini napisan v lestvičnem diagramu z izjemo določenih delov napisanih v strukturiranem tekstu. Na koncu pa je predstavljena funkcionalnost vmesnika človek-stroj. The thesis describes operation and program of an extruder machine, whose control system was renovated within the scope of a project in the INEA company. Extruder is a machine which combines sequential and continuous processes. The result of those is processing of plastics into a product, which is in this case a continuous sheet of variable dimensions. Parts of the project, which were under my responsibility, are described in greater detail. The program itself is split into two parts: a program of programmable logic controller and a program of the human-machine interface. Both are written in Siemens TIA Portal v14 programming tool. The first part of the thesis is dedicated to the description of the machine, its devices and starting sequence. Next, description of the program and it’s structure, which is for the most part written in ladder logic with some exceptions in structured text, is given. In the end, a description of functionality of the human-machine interface is given. ekstruder sekvenčni proces regulacija lestvični diagram strukturiran tekst programirljivi logični krmilnik vmesnik človek-stroj extruder sequential process regulation ladder logic structured text programmable logic controller human-machine interface true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-01-21 10:05:07 2019-01-21 10:05:11 2022-08-18 03:47:39 0000-00-00 00:00:00 2019 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 45181 Spelic_Ziga_-_Obnova_krmiljenja_ekstruderja.pdf Spelic_Ziga_-_Obnova_krmiljenja_ekstruderja.pdf 1 788E069E6D49EAD9A40FC9666CFDBD4D eebc3ec5eb58ebd0326ab8655caf411614e672e472808248cb7371a9bc4a5adc 45abd8fc-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116782 Fakulteta za elektrotehniko 0 0 0
