Avtomatizacija ogrevalnega sistema s programirljivim logičnim krmilnikom Beckhoff

LOGAR, TINE (author), Logar, Vito (mentor)

Dandanes se vse pogosteje odločamo za vgradnjo sistemov, ki nam lajšajo življenje. Želimo si, da čim več stvari deluje samostojno, da lahko svoj čas porabimo kvalitetnejše. Med take sisteme spada tudi avtomatizacija ogrevanja stanovanjskih hiš. Za projekt sem dobil, da se izvede avtomatizacija kotlovnice s krmilnikom Beckhoff. Sistem je že zgrajen in potrebuje samo še programiranje po naročnikovih željah. Sistem je razdeljen na tri dele, in sicer na sanitarno vodo, talno in radiatorsko ogrevanje. Tako talno, kot radiatorsko ogrevanje, je razdeljeno še na tri nadstropja. Talno gretje je nato še krmiljeno preko ventilov v vsakem nadstropju, da si gretje lahko uporabnik nastavi za vsako sobo posebej. Radiatorji pa imajo nameščene termostatske ventile, zato ne potrebujejo posebnega krmiljenja. Naročnik je želel, da lahko nastavlja urnike ogrevanja za vsako nadstropje posebej in odprtost ventilov talnega ogrevanje. Poleg tega je želel imeti kroženje sanitarne vode, da ob odprtju iz pipe takoj priteče topla voda in ni potrebno točiti mrzle vode, medtem ko čaka na toplo. Prav tako je želel, da lahko preko zaslona na dotik spremlja vse merjene in nastavljene veličine v sistemu in po želji spreminja njegove parametre. Le tako si bo lahko celoten sistem nastavil točno tako, kot si želi.

• Title: Automation of the heating system using a Beckoff programmable logic controller

Abstract

Nowadays we are increasingly deciding to install automated systems that makes our lives easier. We want as many things as possible to work independently, so that we can spend our time better. Such systems also include the automation of residential heating. Fort the project I had to program a boiler room with Beckhoff PLC. The system was already built and only needed to be programmed according to the client's wishes. The system is divided into three parts, namely sanitary water, floor and radiator heating. Both floor and radiator heating is divided into three floors. Floor heating is then controlled via valves on each floor, allowing the user to adjust the heating for each room separately. Since the radiators have thermostatic valves installed, they do not require additional control. The client wanted to be able to set the heating schedules for each floor separately and to open the floor valves manually. The client wanted to have sanitary water circulation, meaning that hot water is available immediately when a faucet is opened and no cold water is wasted while waiting for the hot one. Furthermore, the client also wanted to be able to monitor all measured and set values in the system through a touch screen and change its parameters as desired. Only in this way he will be able to set up the whole system exactly as he wants.
