Abstract

U ovom radu opisan je mjerni sustav i sustav komunikacije uređaja C zgrade Fakulteta Elektrotehnike i računarstva u Zagrebu. Opisani su najpoznatiji standardi s naglaskom na onaj kojime se ova elektroenergetska mreža koristi te je objašnjen Modbus protokol komunikacije. Zasebno je opisan svaki dio sustava, tj. mjerni uređaj, logički kontroler i grafički program LabVIEW te su objašnjeni njegovi osnovni principi rada i dodatni modul LabVIEW Real-Time koji nam je ključan za funkcioniranje sustava u stvarnom vremenu. Uz to navedene su i neke mogućnosti sustava koje bi u budućnosti mogle biti nadograđene na sustav.

Abstract (english)

This paper describes the measuring system and the system of communication devices of the C building of the Faculty of Electrical Engineering and Computing in Zagreb. The most well-known standards are described, with an emphasis on the one used by this power network and the Modbus communication protocol is explained. Each part of the system, ie the measuring device, logic controller and graphic program. Also LabVIEW and its basic principles of operation are described with the additional module LabVIEW Real-Time, which is crucial for the functioning of the system in real time. In addition, some features of the system that could be upgraded are listed.
