Abstract

Magistrska naloga obravnava nadgradnjo delovanja hidravlične stiskalnice. Osrednji izziv predstavlja avtomatsko generiranje preoblikovalnega cikla. Z uporabo RFID tehnologije lahko dosežemo hitrejši prenos informacij o naročilu in preoblikovancih. S tem namenom so obravnavani pristopi v pametni proizvodnji in delovanje RFID ter pregledani načini programiranja PLK. V nadaljevanju so opisani hidravlična stiskalnica, krmilnik CX9020, računalnik Raspberry Pi ter RFID čitalnik ACR122U. Med njimi je po protokolih CCID, ADS in AMS vzpostavljena komunikacija. Informacije o naročilu se prenesejo z RFID čipa preko čitalnika do delovnega mesta. Algoritem, ki je naložen na računalnik Raspberry Pi, iz naročila, poznanega vhodnega materiala ter znane geometrije orodja avtomatsko generira preoblikovalne cikle hidravlične stiskalnice. Karakteristične točke cikla pošlje programu na krmilniku stiskalnice. Ob potrditvi delavca se preoblikovalni cikel izvede. Program na Raspberry Pi-ju spremlja število preoblikovanih in preostalih kosov, prav tako pa tudi tip preoblikovanca in potrebne nastavitve orodja. Ob zaključeni delovni operaciji se informacija o stanju delovnega naloga spet zabeleži na RFID čip.

Secondary title: Automatic generation of hydraulic press cycles using the RFID identification of plan
Secondary abstract: The master's thesis covers the improvement of operation of the hydraulic press. The central challenge is to generate the press cycle automatically. By using RFID technology we can achieve a faster transmission of information about the work order and the work-in-progress items. To this end, approaches in smart manufacturing and RFID functionality are discussed, and PLC programming methods are reviewed. Furthermore, the hydraulic press, the CX9020 controller, the Raspberry Pi computer and the ACR122U RFID reader are described. Communication is established between them via the CCID, ADS and AMS protocols. The work order information is transmitted from the RFID tag via the reader to the working station. The algorithm running on the Raspberry Pi automatically generates the working cycles according to the work order, known input material and known tool geometry. It then sends the characteristic points of the cycle to the press controller. Following the confirmation from the worker the press cycle is performed. The program on Raspberry Pi monitors the number of reshaped and remaining pieces, as well as the type of product that is to be made and the necessary tool settings. When the work operations are complete the information about the status of the work order is again recorded on the RFID tag.
