Razvoj naprave za oddaljeni nadzor prenapetostnih zaščit in zajem podatkov

BAŠKOVČ, BLAŽ (author), Kotnik, Tadej (mentor)

V diplomskem delu sem predstavil in opisal razvoj naprave ProALARM II. Naprava je namenjena nadzoru stanja prenapetostnih zaščit in ostalih naprav podjetja, ki omogočajo brez napetostni izhod. ProALARM II nadzira stanja priključene naprave po protokolu progrid in posreduje stanje v nadzorni sistem ProGRID Cloud, ki je namenjen končnemu uporabniku. V uvodnem delu sem na kratko opisal izvore prenapetosti, ki nastanejo v naravi, tipe odvodniških elementov, ki se uporabljajo, prenapetostno zaščito in števce, ki jih izdeluje podjetje. Nadaljeval sem z opisom načrtovanja strojne opreme, opisal ključne komponente (mikroprocesor, napajalno vezje, ščitenje vhodov v napravo, TCP/IP modul, čelno tipkovnico), ki sestavljajo napravo, in predstavil orodje, ki sem ga uporabil med razvojem programskega dela naprave. Delovanje programa sem prikazal z blok diagrami in kratkimi izseki kode, kot so glavna zanka, delovanje in zaznavanje spremembe stanj na vhodih, upravljanje LED diod čelne tipkovnice, komunikacijo RS-232 in delovanje podprogramov s časovniki. V zadnjem delu sem predstavil uporabo spletnega nadzornega sistema ProGRID Cloud, ki se uporablja za pregled podatkov, katere pošlje naprava, uporabo alarmiranja preko spletne pošte in SMS sporočanje. V zaključku pa so podane možnosti izboljšave in nadgradnje naprave.

• Title: Development of a device for remote monitoring of SPDs and data collection

Abstract

In this thesis I presented and described the development of device for remote monitoring of overvoltage protection devices state and other devices of the company. In the introductory part of the paper I briefly described the origins of surges which occur in nature, types of protection elements that are used, overvoltage protection and surge counters manufactured by the company. I continued with a description of the design of hardware, described the key components (microprocessor, power supply circuit, input ports protection, TCP/IP module, front keyboard label), and tool that I used during the development of firmware. Operation of the program is presented with block diagrams and short extracts of code, such as the main loop, operation and detected ports changes, management of LED’s frontal keypad, RS-232 communication and operation routines with interrupt timers. In the last part of the thesis I presented web based control panel ProGrid Cloud, which is used to review the data, sent from the device, using the alarm via e-mail or SMS messaging. In conclusion, I presented possibilities for improvement and upgrading of the device.
