S\u00f5brad, on aeg kokku v\u00f5tta meie projekti-konkurssi \u201eServer pilvedes\u201d tulemused. Kui keegi ei tea, siis me tegime l\u00f5busat geeki projekti: ehitasime v\u00e4ikese serveri Raspberry Pi 3-l, lisasime sellele GPS-j\u00e4lgija ja andureid, laadisime k\u00f5ik selle hea \u00f5hupalli ning usaldasime looduse j\u00f5ududele. Kus pall maandub, teavad ainult tuulet jumalad ja \u00f5hulaevade patroonid, seega pakkusime k\u00f5ikidele soovijatele v\u00f5imaluse m\u00e4rkida kaardile punkte \u2014 kelle punktid on k\u00f5ige l\u00e4hemal tegelikule maandumiskohale, saavad \u201emaitsvaid\u201d auhindu.<\/p>\n

Nii et meie server on juba pilvedes tiirutanud ja on aeg kokku v\u00f5tta meie konkursi tulemused.

    Ja kogemus, poeg raskete vigade kohta<\/h2>\n

    \nNagu te m\u00e4letate, plaanisime edastada andmeid serverist GSM-modemi kaudu. See oli peamine teabe edastamise kanal. Me arvasime, et oleme ette n\u00e4inud k\u00f5ik ootamatused mobiiliv\u00f5rgu katvuses, paigaldades modemisse kaks SIM-kaarti parima katvusega operaatoritelt Dmitrovi piirkonnas. Lisaks oli modemil hea suunatud antenn. Kuid nagu \u00f6eldakse, inimene kavandab, aga operaatorid m\u00e4\u00e4ravad. Kui pall t\u00f5usis \u00fcle 500 meetri (Ostankino televisioonitornist k\u00f5rgemal), kadus mobiilside t\u00e4ielikult. <\/p>\n

    \"Server
    \n
    \nTagantj\u00e4rele m\u00f5eldes n\u00e4ib see ilmselge, kuid see ongi tagantj\u00e4rele. Loomulikult on mobiilside antennid m\u00f5eldud katmiseks maapinnal, mitte \u00f5hus. Nende suunamuster \u201el\u00f6\u00f6b\u201d m\u00f6\u00f6da maastikku ja ei \u201evalgusta\u201d pilvi. Nii et mobiilside poole kilomeetri k\u00f5rgusel ja k\u00f5rgemal on vaid juhuslik uue peegeldus m\u00f5ne antenni lehelt. Seega pool teed mobiilsidega palliga ei olnud. Ja langemisel, kui olime langenud alla 500 meetri, t\u00f6\u00f6tas mobiilside taas.<\/p>\n

    Kuidas me saime kuuldata teavet kuuli kohta? Selle eest on t\u00e4nu andmeseiru dubleerivale kanalile. Me paigaldasime kuule komplekti LoRa-raadiotehnoloogiat<\/a><\/noindex>, mis t\u00f6\u00f6tab sagedusel 433 MHz. <\/p>\n

    \"Server
    \n
    \nSelle l\u00e4bilaskev\u00f5ime ei ole suur, kuid meie \u00fclesannete jaoks oli seda t\u00e4iesti piisavalt. Ja mis puudutab kuuli asukoha m\u00e4\u00e4ramist GPS-i j\u00e4rgi, siis sellega ei ilmnenud mingeid probleeme, j\u00e4lgija t\u00f6\u00f6tas t\u00f5rgeteta.<\/p>\n

    \"Server
    \n
    \nJa lennu ajal selgus, et USB-kaabel, mis \u00fchendas telemeetriamooduli Raspberry Pi 3-ga, oli defektne. Maandudes t\u00f6\u00f6tas see, kuid lennates andis otsad. Ilmselt kartis k\u00f5rgust. Kaabli viga avastasime alles p\u00e4rast maandumist. \u00d5nneks suutsime andmeedastust otse telemeetriamoodulist LoRa kaudu taastada.<\/p>\n
