20.500.12556/DKUM-54771 ANALIZA PREJETIH PODATKOVNIH PAKETOV V DIGITALNEM KOMUNIKACIJSKEM STANDARDU DMX512 ANALYSIS OF RECEIVED DATA PACKAGES IN DMX512 DIGITAL COMMUNICATIONS STANDARD Diplomska naloga je v teoretičnem delu posvečena vsebini in načinu delovanja digitalnega komunikacijskega standarda DMX512, v drugem delu pa izdelavi tiskanega vezja, ki omogoča komunikacijo preko protokola RS-485, ter dekodiranju signala DMX512 s pomočjo prototipne ploščice STM32F407VG Discovery. Delo vsebuje temeljne povzetke standarda DMX 512, ki so potrebni za nadaljnje delo, saj je poudarek praktičnega dela na razpoznavanju in dekodiranju signala DMX512, za kar je potrebno tudi teoretično predznanje. Opisanih je več pristopov do razpoznavanja signala in izgradnje filtrov, navedenih je tudi nekaj prednosti in slabosti posameznih rešitev. Rezultati so pokazali, da je možno konstruirati filtre, s katerimi lahko zaznamo določene napake, vendar se pri implementaciji teh filtrov pojavljajo težave, ki so posledica ohlapnosti standarda v določenih segmentih. The theoretical part outlines the main characteristics and operational properties of the DMX512 communication standard, while in the second part the construction and manufacturing process of the circuit board, enabling communication using RS-485 protocol, and decoding the DMX512 signal using the prototype STM32F407VG Discovery board is described. As the main emphasis of the practical part of the project lies on the recognition and decoding of the DMX512 signal, the fundamental properties of the DMX512 standard, required for further work, are briefly outlined. Different possible approaches for signal recognition and construction of appropriate filters are discussed, objectively assessing performance, pros and cons of each option. We conclude that the topic of DMX512 signal analysis is a very interesting one, although very tedious and complicated. Nevertheless the project has shown potential for developing accessible high-quality technological solutions at home.
