Abstract
This paper presents a centralized solution for network communication and control of remote devices aimed for partial discharge monitoring. Java SWT server application (user interface) is realized for that solution. Server user interface is intended to replace the remote desktop in the local network. The remote desktop is replaced due to limitations imposed by the extension of the monitoring system. As the monitoring system for partial discharge is installed on five more generators, there arise a need to centralize data on server computer. The server user interface is located on server (monitoring pc) and communicates with Java SWT client applications installed on local computers. The partial discharge monitoring application software runs on local computers. All relevant informations for end user are transmitted using server-client connection. The server user interface has two access levels: administrator and user. Depending on the access level it is possible either only to observe monitoring parameters or to change parameters and to give commands.
Sažetak
U radu je predstavljeno centralizovano rešenje za mrežnu komunikaciju i kontrolu udaljenih uređaja za monitoring parcijalnih pražnjenja. Za tu priliku razvijena je Java SWT serverska aplikacija (maska). Serverska maska ima ulogu da u lokalnoj mreži zameni takozvani udaljeni pristup računaru (remote desktop). Udaljeni pristup je potrebno zameniti zbog ograničenja koje se javilo proširenjem sistema za monitoring. Kako je sistem za parcijalna pražnjenja bilo potrebno instalirati na pet novih generatora, javila se i potreba za centralizovanjem podataka na serverski računar. Serverska aplikacija putem ethernet-a komunicira sa Java SWT (standard widget toolkit) klijentskim aplikacijama koje se nalaze na lokalnim računarima. Na lokalnim računarima se obavlja monitoring parcijalnih pražnjenja. Sve bitne informacije za krajnjeg korisnika se prenose vezom server-klijent. Serverska maska ima dva nivoa pristupa korisnički i administratorski. U zavisnosti od nivoa pristupa moguće je samo posmatrati parametre ili izdavati komande i menjati parametre.
