Elektronski modul za dvožično napajanje in komunikacijo s senzorji

Rupar, Jakob (author), Žemva, Andrej (mentor)

Povečanje avtomatizacije prinaša vsakič večjo željo po poenostavitvi izdelave robotov ter povečanju zanesljivosti. Zato se na trgu pojavljajo nove rešitve, ki bi pripomogle k hitrejšem razvoju robotov. Združevanje napajanja in komunikacije po istih vodnikih je v robotskih sistemih novost, kar hkrati pomeni, da je število tovrstnih rešitev še majhno in posledično drago. V RLS Razvojno-inovacijskem laboratoriju smo se odločili za razvoj lastnega modula, ki bi konkuriral trenutnim rešitvam pri znatno nižji ceni. Modul deluje s pomočjo 8-bitnega mikrokrmilnika, ki ne glede na svojo nizko ceno ponuja ogromno fleksibilnosti, kar je ključnega pomena za izdelavo takšnega sistema. V delu je opisan potek razvoja, od same izbire komponent do delovanja napajanja in komunikacije. Glede na začetne zahteve so v rezultatih opisane metode za merjenje in nekatere optimizacije za izboljšanje delovanja. Na koncu je dodana še primerjava med zahtevami in prvo izvedbo modula. Razviti modul je trenutno v takšni fazi, da že lahko konkurira ostalim rešitvam na trgu. Določene funkcionalnosti, ki bi povečale njegovo vrednost, še niso implementirane. Tako obstaja še nekaj prostora za dodatne raziskave in optimizacijo delovanja.

• Title: Electronic module for two-wire power supply and communication with sensors

Abstract

The increasing automation always brings a greater desire for simplifying the manufacturing of robots and enhancing their reliability. Hence, new solutions are emerging in the market, which could contribute to the faster development of robots. The combination of power supply and communication through the same conduits is a novelty in robotic systems, which also means that the number of such solutions is still small and consequently expensive. In the RLS Development and Innovation Laboratory, we have decided to develop our own module that would compete with the current solutions at a significantly lower price. The module operates with the help of an 8-bit microcontroller, which, despite its low cost, offers immense flexibility, which is crucial for the creation of such a system. The work describes the course of development, from the selection of components to the operation of power supply and communication. Based on the initial requirements, the results describe the methods for testing and some optimizations for improving operation. A comparison between the requirements and the first implementation of the module is added at the end. The developed module is currently at a stage where it can already compete with other solutions in the market. Certain functionalities, which would increase its value, are not yet implemented. Thus, there is still some room for additional research and optimization of operation.
