Keskkonnaseire hõlmab endas keskkonnaseisundi ja selle parameetrite mõõtmist, kogumist
ja töötlemist. Keskkonda iseloomustavad andmed on põllumajanduse efektiivsemaks
muutmisel oluliseks sisendiks. Andmete põhjal loodud mudelite alusel on võimalik
korraldada taimekultuuride tulemuslikumat kasvatust, sest nii on võimalik planeerida
muutuvatest keskkonnatingimustest sõltuvaid tegevusi. Valminud süsteem koosneb viiest
eraldi seisvast seadmest. Nendeks on kolm andurjaama, tugijaam ja keskseade.
Andurjaama projekteerimisel seati ülesanneteks, et seade peab olema suuteline mõõtma
kolme erinevat temperatuuri- ja mulla niiskusanduri väärtust, töötama patareitoitel ühe
vegetatsiooniperioodi, suutma andmeid edastada tugijaama võimalikult kauge vahemaa
tagant kasutades selleks taskukohase hinnaga raadiosidemoodulit ja olema võimalikult
kompaktne. Tugijaam on suuteline vahendama infot andurjaamade ja keskseadme vahel.
Keskseade salvestab kõik saabunud infopaketid ja töötleb neid lõputöö raames valminud
programmis.
Andmehõivesüsteemi katsetamine viidi läbi ajavahemikus 10.04.2018-22.04.2018.
Andurjaamad paigaldati 100 meetri raadiusse tugiseadmest. Katse tulemusena ilmnesid
andurjaamade töös üksikud tõrked. Katsete tulemusena tõdeti, et andmehõivesüsteem on
rahuldavalt suuteline töötama väliskeskkonnas ja andma kasutajale reaalajas infot õhu ja
mulla olekuparameetrite kohta. Töö autor leiab, et kavandatud süsteemil on mitmeid
edasiarendus võimalusi. Näiteks valmistada andurjaamale lokaalne infosalvestamise
võimalus või kavandada andmehõivesüsteemile juurde häiresüsteem, mis saadaks
kasutajale hädavajalikku informatsiooni.
Environmental data acquisition involves measuring, collecting and processing the environmental parameters. Models created on the basis of environmental data can be used, for example, for more efficient cultivation of plants, because the yield of plants depends highly on the surrounding environmental conditions. The aim of this Master's thesis is to design and construct a data acquisition system for soil and air parameters. The completed system consists of five stand-alone units which are the three sensor stations, a base station and a central unit. The author of the thesis formulated sensor station system requirements as following: to be able to measure three different temperature and soil moisture sensor values, to work on battery power during one vegetation period, to be able to transmit data from the base station as far away as possible, using an affordable radio module and be as compact as possible. The base station is capable of communicating between sensor stations and the central processing unit. The central unit stores all received information packets and processes them in the program completed under the master thesis. Testing of the data acquisition system was carried out between 10.04.2018-22.04.2018. Sensor stations were installed at a radius of 100 meters from the central unit. As a result of the experiment, some minor faults were detected in the sensor stations. The data acquisition system was capable of providing real-time information about air and soil parameters in the external environment. The author of the paper considers that the proposed system has several possibilities for further development. For example, prepare a local information storage device for the sensor station or an alarm system for the data acquisition system to provide the user with the essential information.
