Virtuální Datalogger na bázi NI cRIO

Abstract

The dissertation deals with problems of scanning electrical signals, their archivation and possibility of visual reproduction. Datalogger is designed as virtual instrument. Instrument is based on PC and embedded system CompactRIO with FPGA industry modules I/O. CompactRIO hardware is open hardware architecture, connecting controller to processor and RTOS, programmed FPGA logic array and I/O modules in one chassis. All created by National Instruments company. Input signals are digitized and viewed on PC monitor. There is also possibility of data saving into hard disc files. We can view and analyze older stored data too. Inputs are analog and digital signals. Digitized data can be processed by filters. We can also apply other function as add, inverse, derivate, integrate, FFT analysis.
