Nadzor vodovodnega omrežja

Potočnik, Gašper (avtor), Bešter, Janez (mentor)

V diplomskem delu je predstavljen pojem »internet stvari«. Opisana je zgodovina povezovanja naprav v skupno omrežje ter pojav termina internet stvari. Opisanih je nekaj splošnih primerov IoT, kot so pametni prenosni elektronski dodatki, pametni domovi in pametna mesta. Predstavljene so prednosti tovrstnega povezovanja med napravami ter priložnosti za optimizacijo procesov v transportu, infrastrukturi in varčevanje z naravnimi ter drugimi viri tako v zasebnem sektorju kot v industriji. V drugem delu je predstavljen vodovodni sistem vasi Zgornja Besnica pri Kranju. Opisan je razvoj vodovodnega sistema skozi čas ter težave, ki se pojavljajo na cevovodu in povzročajo izpad dobave vode porabnikom. Predstavljene so možnosti za avtomatizacijo ter sistematičen pristop k realizaciji implementacije nadzornega sistema v sistem vodovodnega omrežja. Predstavljena je razdelitev načrtovanih meritev v tri dele, ki bodo omogočali postopno dodajanje merilnih mest skupnemu nadzornemu sistemu. V 5. poglavju je predstavljena rešitev za avtomatizacijo vodovodnega sistema v obsegu, ki ga zajema prvi del. V tem delu se zajame meritve pretokov, tlakov in nivojev na dveh lokacijah – v zgornjem rezervoarju ter na območju vrtine. Predstavljena je oprema, ki omogoča zajem podatkov, to so senzorji pretoka, temperature in tlaka, potem krmilnika, locirana na omenjenih lokacijah, način programiranja v lestvični logiki ter posamezni programi za zajem in obdelavo zajetih podatkov ter medsebojno komunikacijo. Opisan je tudi postopek obveščanja upravljavcev in možnost razširitve sistema s spletnim uporabniškim vmesnikom, ki bi posameznikom omogočal vpogled v stanje sistema. Predstavljena sta še drugi in tretji sklop meritev, ki bi omogočila podrobnejši vpogled v stanje sistema. Na koncu je predstavljen ciljni načrt, meritve, zajete v vseh treh delih načrta, težave, ki onemogočajo izpeljavo projekta nadzora v enem delu. Predstavljena je tudi priložnost, ki bi jo nudil celoten sklop meritev za nadzor in upravljanje z vodovodnim omrežjem, predvsem možnosti za zanesljivejše in upravljavcu prijaznejše omrežje.

The diploma thesis presents the concept of the Internet of Things. It describes the history of device connection into common network and the emergence of the term Internet of Things. There are described some general IoT use cases such as smart wearables, smart house, smart city and the possibilities and opportunities of such type of interconnection for optimization of processes in transportation, infrastructure, saving of natural and other resources both in private and in industrial sector. The second part presents water supply network for the village Zgornja Besnica near Kranj. It describes the development of the system through time and the problems which occur on the pipeline, causing loss of water supply to consumers. It presents possibilities for automation and systematic approach to the realization of the control system implementation to the water supply network. Concept of automation implementation is divided to three main phases, which will allow partial adding of measuring points to the automation system. Chapter 5 presents a solution for the automation of the water supply system to the extent covered by the first set of measurements. In this part, data from the higher tank location and data available in the area of the well are captured. Presented is the equipment, which allows data capturing, water flow, temperature and pressure sensors and industrial controllers. Later on is presented the ladder diagram type of microcontroller programming language, parts of program for data acquisition, processing and communication between parts of the system. Also there is part which describes how the managers of the system are informed about the water system status and the possibilities of system extension with web user interface, which would allow users to observe system status. Described are also the second and third set of measurements, planned additional measurement points and impact of implementation which would present bigger picture on village water management system. At the end there is presented whole automation system, which would cover all measurements from parts 1, 2 and 3 and possibilities which would such set of captured data offer to make water distribution system more reliable and manager friendly.
