Razvoj komunikacijskega vmesnika po standardu RS 485

ALEŠ, PETER (author), Agrež, Dušan (mentor)

Diplomsko delo zajema proces razvoja elektronske strojne opreme za RS485 komunikacijo, namenjeno za komunikacijo med elektronskimi električnimi števci delovne energije podjetja Iskraemeco. V uvodnem delu so predstavljene vrste kominikacij in ostalih vmesnikov, ki se uporabljajo za daljinsko upravljanje in odčitavanje električne energije. Cilj je bil izdelati tri variante RS485 vmesnika in opisati proces načrtovanja, ki zajema osnovno idejo, izbiro konceptov, izbiro komponent in predvidevanje obnašanja sistema s pomočjo simulacije. Na podlagi izvedenih testnih procedur in rezultatov meritev je bila opravljena primerjava različic po funkcijskih lastnostih, dimenzijah, ceni in zanesljivosti s FMECA analizo.

Abstract

The Diploma thesis describes the process of development of electronic hardware for RS485 communication used for communication between electronic electric meters made by Iskraemeco. In the beginning is description of types of communication and interfaces for remote control and reading of electrical energy. The goal was to build three versions of the RS485 interface and describe process, which comprises the principle idea, selection of concepts, selection of components, and prediction of system performance using simulation. Based on test procedures and measurement results, different versions were compared according to their functions, dimensions, price and reliability analysis with FMECA.
