Zasnova in izvedba elektronskega sistema za upravljanje električne samokolnice

SITAR, MITJA (author), Žemva, Andrej (mentor)

Magistrsko delo obravnava načrtovanje in izdelavo tiskanega vezja, ki deluje kot povezovalni člen med posameznimi električnimi sklopi na intuitivni električni samokolnici. Tiskano vezje je inovativno zasnovano, saj spremlja trenutne električne parametre in na podlagi njih določa naslednja stanja. V nalogi najprej govorimo o obstoječih izdelkih ter o njihovih pomanjkljivostih, nato pa se osredotočimo na zasnovo našega. Opisan je postopek prijave patenta za naš celoten izdelek ter opisi uporabljenih električnih sklopov - motorja, baterije in krmilnika. V drugem sklopu je podrobneje opisana zasnova tiskanega vezja ter posameznih komponent. Tiskano vezje je osnovano okoli mikrokrmilnika ESP32, ki komunicira in upravlja z ostalimi moduli in bloki vezja, kot so: stikalni napajalniki, gumb, kombinacijsko vezje, digitalni ter analogni deli vezja. V tem sklopu je predstavljena tudi simulacija kritičnih signalov s pomočjo programskega okolja. V tretjem sklopu so opisane meritve, testiranja na terenu, ter predstavljene izboljšave in rezultati.

Abstract

The purpose of this Master's thesis is hardware engineering and designing a printed circuit board which acts as a connection between individual electrical assemblies. Printed circuit board can monitor current state of the system and based upon them, determines next parameters. In the first few chapters we take a look at existing similar products and describe their deficiencies, after which we talk about our product. We describe our patent application and describe our electrical assemblies - motor, batteries and controller. In the next few chapters we describe our printed circuit board and indvidiual components. It is designed around microcontroller ESP32 which communicates and manages with other electrical modules and blocks, such as: switching power supplies, button, combinatorial circuit, digital and analogue part. In this section, we also discuss about simulations of some of the critical signals. In the third part of Master's thesis, we discuss about measurements, testing on the go, improvements and final results.
