Mikrokrmilniški regulator ventilacijskega sistema za industrijske elektro omare

Plahuta, Tilen (author), Murovec, Boštjan (mentor)

Diplomsko delo obsega zasnovo, razvoj in izvedbo regulatorja prezračevanja za industrijske aplikacije, ki potrebujejo ustrezno hlajenje notranjosti električnih omar. Da bi zagotovili ustreznost za industrijske razmere, vse elektronske komponente, uporabljene v napravi, ustrezajo industrijskim standardom. Namen naprave je regulacija hitrosti ventilatorjev, ki jo krmilimo s spreminjanjem efektivne napetosti. Cilj je učinkovito hlajenje industrijskih električnih omar, hkrati pa tudi podaljšanje življenjske dobe filtrov ventilatorjev. Ti filtri so bistveni za preprečevanje vstopa prašnih delcev v notranjost ohišja. Osrčje krmilnega sistema je mikrokrmilnik, ki nadzoruje in upravlja delovanje sistema ter omogoča komunikacijo s programirljivim logičnim krmilnikom (PLK) proizvajalca Siemens. Uporabniški vmesnik je izveden z uporabo LCD zaslona in tipk, s katerima lahko uporabnik nastavi želeno referenčno temperaturo. Poleg tega ima naprava vgrajen modul za brezžično povezavo, ki omogoča spremljanje temperature v realnem času prek platforme ThingSpeak. Naprava je izdelana na tiskanem vezju in je nameščena v ohišju za montažo na DIN letev, kar olajša namestitev. Rezultat dela je naprava, ki uspešno izvaja vse opisane funkcije in uporabniku omogoča intuitivno in preprosto uporabo.

• Title: Microcontroller based ventilation system for industrial electrical enclosures

Abstract

The thesis covers the design, development and implementation of a ventilation controller for industrial applications that require adequate cooling of the interior of electrical enclosures. To ensure suitability for industrial conditions, all electronic components used in the device comply with industry standards. The purpose of the device is to regulate the speed of the fans, which is controlled by varying the effective voltage. The aim is to provide efficient cooling of industrial electrical enclosures, while at the same time extending the lifetime of the fan filters. These filters are essential to prevent dust particles from entering the interior of the enclosure. At the heart of the control system is a microcontroller that monitors and controls the operation of the system and allows communication with a programmable logic controller (PLC) from Siemens. The user interface is implemented using an LCD display and keys that allow the user to set the desired reference temperature. In addition, the device has a built-in wireless module that allows real-time temperature monitoring via the ThingSpeak platform. The device is manufactured on a printed circuit board and is housed in a DIN-rail mounting enclosure, which facilitates installation. The result of the work is a device that successfully performs all the described functions and allows the user to use it intuitively and easily.
