Abstract

Ovim radom proučena su raspoloživa komunikacijska sučelja brojila električne energije. Osim samih komunikacijskih sučelja dan je i kratki opis principa rada brojila. Brojila imaju standardizirani način komunikacije koji je jedinstven za sva korisnička sučelja i odvija se prema IEC 62056-21 mod C protokolu. Dan je kratki opis pojedinog komunikacijskog sučelja, a ostvarenje komunikacije je detaljno opisano po koracima. Za prikupljanje i prikaz podataka koristi se GSN sustav čiji je kratki opis i uvod u rad s istim također dan u tekstu. Opisani su programski omotači i opisnici virtualnih senzora kao i način njihove izrade te puštanja u rad. Za potrebe testiranja razvijena je konzolna korisnička aplikacija koja omogućava slanje upita prema brojilu te po potrebi dodavanje novih upita u aplikaciju. Navedeni su svi korišteni programi i biblioteke i opisane su poteškoće na koje se naišlo tijekom rada. Nastojanje je čim bolje opisati cjelokupni rad s brojilima kako bi se nekada u budućnosti moglo nastaviti s radom imajući kao podlogu čim kvalitetniju dokumentaciju.

Abstract (english)

This paper studied the available communication interfaces of electricity meters. Apart from the communication interfaces, a brief description of the electricity meter work principles is given. The meters have a standardized way of communication that is unique for all user interfaces and carried out according to IEC 62056-21 Mode C protocol. A brief description of each communication interface, and the realization of communication is described in detail in steps. To collect and display data GSN system is used and its brief description and introduction to the work of the same is also given in the text. Wrappers and descriptors of virtual sensors are described and also the method of their writing and running. For testing purposes a console application is developed which allows users to send queries to the meter and, if necessary, add new queries in the application. All required and used programs and libraries are listed and described. Also there are describes of the difficulties encountered during operation. The effort is as better as it can to describe a complete work with the meters to be used in the future to continue working with electricity meters having better documentation available.
