Návrh a realizace SW pro vyčítání dat z digitizéru

Abstract

The content of this bachelor thesis is to create a program in the LabVIEW environment, as a cornerstone for working with a digitizer. Digitizer is a measuring device supplied by 32dev s.r.o. The digitizer samples 9 analog channels with a sampling frequency of 243,500 samples per second. These are 4x high voltage inputs with ranges from 350 V up to 1.5 kV. Digitizer also has 1x direct current input with a measurable range of 20 mA to 5 A. The last are 4x Rogowski coils with ranges from 0.5 V to 5 V. Each of these measured channels has its own 20-bit ADC. Digitized measured data are sent in the form of continuous current over the network via Ethernet to a PC. The UDP communication protocol is used as a method of data transfer. The received data in the program are decoded and processed in the form of a graph. The measured signal is analyzed with the option to save the measured waveforms to a file in TDMS format.
