Development of the Water Mist Canopy Control System
No full textKäesoleva lõputöö eesmärgiks oli arendada ETS NORD AS-i NORDcanopy tooterühma
kuuluvale veekubule uue generatsiooni juhtimissüsteem, mis teostaks kubu valgustuse,
veesõlme ja väljatõmbeklapi ajamite juhtimist ning veesõlmes veetrassi ja veekulu
monitoorimist. Valminud juhtimissüsteemi jaoks arendati valmis veekubu juhtimiskilp ja
uus veesõlm, läbi mille jõuab vesi kubusse. Lõputöö käigus analüüsiti turul olevaid
lahendusi, toodi välja süsteemi nõutud funktsionaalsused ja tööpõhimõtted, kirjeldati
toodete arendamisega seotud arendusetappe ja sellest tulenevalt töötati välja terviklik
juhtimissüsteem.
Arendatud veesõlme esmaseks eesmärgiks on juhtida vett kubusse ja seeläbi teostada
trassi rõhu ja veekulu monitoorimist. Lõputöö raames valiti veesõlme väljatöötamiseks
sobivad elektrilised ja mehaanilised komponendid etteantud parameetrite järgi, milleks oli
siseneva ja väljuva veetoru läbimõõt ½“ ning kubusse siseneva veetorustiku rõhk peab
olema 2 bar juures.. Veesõlme monitoorimine lahendati rõhuanduriga veesõlme alguses ja
veekulu anduriga peale solenoid ventiili. Rõhuandur annab süsteemile loa veekubu
veesüsteemi käivitamiseks ja kuluandur jälgib, et vesi jõuaks kubusse ning annab
tagasisidet kubus paiknevate veepihustusdüüside ummistumisest.
Lõputöö käigus arendatud juhtimissüsteemi juhtimiskilp teostab veesõlme, kubu
valgustuse ja väljatõmbeklapi ajamite juhtimist ning teavitab kasutajat süsteemis tekkinud
häiretest läbi LED-teavituspaneeli või kubu valgustuse vilgutamisega. Valminud
juhtimissüsteemi saab juhtida läbi kubu küljes oleva kahe nupu, millest üks on valgustusele
ja teine veesõlmele. Juhtimiskilbi võimekuses on ühilduvus hooneautomaatikaga, et
viimane saaks informatsiooni süsteemi tööolekute ja häirete kohta. Hooneautomaatika
ühilduvus on läbi releeväljunditelt tulenevate olekusignaalidega või Modbus andmeside
TCP/IP protokolli kaudu. Väljatöötatud juhtimiskilbi arendus hõlmas endas süsteemi
sisendite ja väljundite kaardistamist, mis oli eelduseks juhtimiskontrolleri valikul,
komponentide valikut, elektriskeemide koostamist ja kontrolleri tarkvara loomist koos
juhtimisalgoritmiga.
Valminud ETS NORD AS-i veekubu juhtimissüsteemi arendusega täideti kõik esitatud
eesmärgid ja funktsionaalsused, mis olid eelduseks süsteemi edukaks toimimiseks ja
konkureerimiseks areneval ventilatsiooniturul.The aim of this thesis was to develop a new generation control system for the water mist
canopy in the NORDcanopy product group of ETS NORD AS. The system is designed to
control the canopy’s lighting, water control unit, and exhaust valve actuators, as well as to
monitor pressure of the water pipeline and water consumption within the water control
unit. A control unit and a new water control unit, which directs water to the canopy, were
developed for the control system. The thesis includes an analysis of existing solutions on
the market, outlines the required functionalities and operating principles of the system,
describes the development stages and presents the resulting control system for the water
mist canopy.
The primary goal of the developed water control unit is to direct water to the canopy and
monitor pipeline pressure and water consumption. For the development of the water
control unit, suitable electrical and mechanical components were selected based on
predetermined parameters, including an inlet and outlet pipe diameter of ½", and a
pressure of 2 bar for the water entering the canopy. The monitoring of the water control
unit was implemented using a pressure sensor at the inlet of the water control unit and a
flow sensor after the solenoid valve. The pressure sensor enables the activation of the
canopy’s water system, while the flow sensor ensures that water reaches the canopy and
provides feedback on blockages in the water spray nozzles located in the canopy.
The control unit developed during the thesis manages the water control unit, canopy
lighting, exhaust valve actuators and notifies the user of system malfunctions through an
LED notification panel or by flashing the canopy’s lighting. The control system can be
operated via two buttons located on the canopy, one for lighting and the other for the
water control unit. The control unit also supports integration with building automation
systems, providing operational and fault status information. Compatibility with building
automation is achieved through status signals from relay outputs or via the Modbus TCP/IP
communication protocol. The development of the control unit involved mapping the
system’s inputs and outputs, which was crucial for selecting the appropriate controller,
choosing components, creating electrical schematics, and developing the controller
software along with the control algorithm.
The development of the ETS NORD AS water mist canopy control system successfully
achieved all the stated objectives and functionalities, ensuring the system's effective
operation and competitiveness in the evolving ventilation market

The official reason for this gathering was to discuss the role of creative unions in carrying out the decisions of the 27th Congress of the CPSU and preparing for the 9th all-union party conference. At the same time, the plenum of creative unions represented the transformation of cultural sphere into political sphere, and therefore, constituted the breaking point of the times of perestroika and a step closer on the way towards the independence of the Republic of Estonia. As architect and the organizer of the plenum of creative unions Ignar Fjuk said in an expert interview: “When this event was over, it was called the new parliament of Estonia”.
During the two-day plenum the speeches were given by 14 writers, 8 journalists and architects, 6 theater people, 4 artists, 2 musicians, historians, candidates of philosophy and one candidate of philology. The floor was also taken by five politicians of whom Indrek Toome, the Secretary of the Estonian Communist Party (ECP), occupied the highest position. Toome said the opening words of the plenum and, also, summed it up.
The results of the expert interviews conducted in the course of this study enable to conclude that the plenum was a successful rhetorical action the aim of which was to ensure as democratic regime as possible by elating the nation and undermining the authorities. All the other raised questions served the purpose of the main goal without attracting greater individual attention.
Both qualitative and quantitative analyses of the content and the interviews allow to conclude that the plenum of creative unions in 1988 is characterized by constant growth and development of reflexivity emanating from verbalization. There was a significant shift from collective values towards individual values. The supporting factors were the forethought of the organizers of the activity and the constant analysis and planning of the plenum. The plenum of creative unions was an important milestone in the process of formulating the idea
of independence. The question of autonomy and state regime that was mentioned by Mikk Mikiver in the opening words of the plenum and summed up by Indrek Toome was the central issue that was directly or insinuatively discussed during the two days. The most prevalent problem/example was the sustainability of the nation. Thus, it could be said that, emotionally, the plenum was focused on the mental and cultural preservation of the nation, and on the basis of that the main subject was profoundly developed idea of the independence.
Largely because of the plenum of creative unions in 1988, where the ideas were intensively generated and vigorously formulated, the vague perception of the independence started to turn to more and more realistic vision, which, in turn, played a significant role in achieving the independence of Estonia just three years later. Ideas are born in exchange of opinions.
In the course of the study the author used content analysis and grounded theory on which the qualitative analysis of texts and interviews was based. For the purposes of this study the interviews were conducted with four representatives of the creative unions and one representative of the soviet power. The interviews were conducted with architect Ignar Fjuk, writer Paul-Eerik Rummo, singer and actor Tõnu Tepandi, artist Heinz Valk and the Secretary of the ECP Indrek Toome.
The plenums of creative unions are described, for example, in the memoirs of the people who participated in them; in 2003, a conference “15 aastat loomeliitude pleenumist“ (15 years from the plenum of creative unions) was organized; and each year, on the anniversary of the plenum, different articles on the subject are published, but this is the first, and hopefully not the last, academic study on the plenums of creative unions.http://tartu.ester.ee/record=b2569071~S1*es
