Abstract

U ovom diplomskom radu razmotrene su metode mjerenja malenih kapaciteta s primjenom u električnoj kapacitivnoj tomografiji. Predložena je arhitektura sklopovskog rješenja višekanalnog sustava za mjerenje kapaciteta s primjenom u električnoj kapacitivnoj tomografiji. Razvijeni su i predloženi prototipovi jednokanalnog i višekanalnog sustava. Sustav se sastoji od generatora sinusnog valnog oblika realiziranog DDS sklopom, izlaznog pojačala, ulaznog nabojskog pojačala, antialiasing filtra, A/D pretvornika, sklopki za odabir pojačanja i načina spajanja elektroda. Razvijena je osnovna programska potpora za STM32F4xxx porodicu mikrokontrolera za potrebe testiranja rada sustava.

Abstract (english)

In this thesis methods for small capacitance measurement were elaborated, with particular emphasis on electrical capacitance tomography (ECT) applications. Architecture of hardware for multichannel measurement system for ECT was proposed. Prototype implementations of single and multi channel measurement systems were developed and proposed. The system consists of sine wave generator using DDS, output amplifier, input charge amplifier, antialiasing filter, A/D converter, and analog switches for gain and electrode selection. The basic software for STM32F4xxx microcontroller family for test purposes was developed.
