Projekti alguses defineeriti tarkmaja juhtimissüsteemi seadmete omadused ja
funktsionaalsuse lähtuvalt seadmete rakendusvõimalusest. Töös kirjeldatakse vabavaralisel
tark- ja riistvaral baseeruvat prototüüpseadmete süsteemi ja seadmete ehitust ning
katsetust. Projektis kavandati ja koostati madala maksumusega targa maja seadmete
süsteem, mis on funktsionaalsuse osas konkurentsivõimeline teiste töös võrreldud
seadmetega. Seadmete süsteem koosneb veebiserveri põhimõttel töötavast seadmete
haldustarkvarast Domoticz, keskarvutina töötavast Raspberry PI-st ning alamseadmetest,
mis suhtlevad juhtmevabalt keskarvuti lüüsiga (ingl gateway), mille üks osa on
raadiojaamamoodul NRF24L01+. Alamseadmed koosnevad toiteahelast,
mikrokontrollerist, raadiojaamamoodulist ning anduritest, releedest ja lülititest. Kavandamise
protsessis defineeriti projekteeritavate seadmete funktsionaalsused ning anti
prototüüpseadmetele nimetused: a) patareitoitel andurseade, b) Nutipesa, c) elektrienergia
arvesti, d) temperatuuri ja õhuniiskuse mõõtmise ning liikumistuvastuse seade. Projekti
käigus viidi läbi andurseadme voolutarbe mõõtmise katse ning patarei teoreetilise eluea
arvutus. Katsete käigus töötati välja metoodika raadiojaamamooduli levi kauguse ja
kvaliteedi hindamiseks.
Lõputöös kirjeldatud seadmete süsteem on kasutusele võetav kohas, kus on vajadus
elektriseadmete juhtimiseks, monitoorimiseks ning anduritega andmehõiveks. Projekti
eesmärgiks olnud targa maja juhtimissüsteemi prototüüpseadmete valmisehitamine,
katsetamine ning töölerakendamine õnnestus täies mahus. Prototüüpseadmete kavandamise
esimeses etapis seadmetele esitatud nõuded täideti.
The characteristics and functionality of the smart house automation system devices were defined in the early stage of the project according to the use. This project describes a prototype device system based on freeware and open hardware and the building and testing of the devices. A low-cost smart house system was designed which is able to compete with existing equivalents in the market. The system consists of managing software Domoticz, central computer Raspberry PI and slave devices that communicate wirelessly with the gateway (one part of it is NRF24L01+ radio module). The slave devices consist of a power circuit, microcontroller, radio module and sensors, relays and switches. The functions and names of the devices were defined in the planning process: a) battery powered sensor device, b) smart plug, c) power meter, d) device for measuring temperature, humidity and identifying movement. A test for measuring the sensor device's power consumption and a calculation of the theoretical battery life were conducted. Methods for evaluating the distance and quality of the radio module signal were developed. The described device system is usable in places where there is a need for controlling and monitoring electrical appliances and for data acquisition with sensors. The aim of this project, which was to build, test and implement prototype devices for the smart house system, was reached successfully. The requirements for the prototype devices (given in the first stage of planning) were met fully.
