Berrito waxaan u diri doonaa server-kayaga stratosphere. Inta lagu jiro duulimaadka, buufinku wuxuu bixin doonaa gelitaanka internetka, qabashada iyo u gudbinta xogta fiidyowga iyo telemetry dhulka. Waxaan qornay dhowr jeer inaan wadaagno faahfaahinta farsamada ee mashruucayaga "Xarunta Xogta Goobta" (horey loo yiqiin "") Waanu balan qaadnay - waanu ilaalinaynaa!
server web
Xataa mashruucii hore ee "Server in the Clouds", markii aanu ku fuulnay buufin hawada kulul oo buuxa oo ay saaran yihiin shaqaale laba ka mid ah, qaadashada server buuxa oo batari batari ah, miyaan nidhaahnaa, wax aan macquul ahayn. Hadda waxaan ka hadleynaa buufin yar oo stratospheric ah oo kori doona 30 km halkii uu ka ahaan lahaa 1. Sidaa darteed, waxaan dooranay Raspberry Pi la mid ah server-ka webka. Kumbuyuuterkan yar ayaa soo saari doona bog HTML ah oo ku soo bandhigi doona bandhig gaar ah.
Isku xirka dayax-gacmeedka
Marka lagu daro Raspberry Pi, modem ka Iridium iyo shabakadaha isgaarsiinta satalaytka Globalstar ayaa saarnaan doona. Sida aad xasuusan karto, waxa aanu qorshaynay in aanu ku darno modem ka shabakada Gonet-ka gudaha darajooyinkooda, laakiin maanu haysan wakhti aanu ku helno wakhtigeeda, markaa waxaanu u diri doonaa duulimaadka xiga. Adeegga shabakada waxa uu fariimahaaga ku heli doona modemka satalaytka, kaas oo loo diri karo Farimahan waxaa loo gudbin doonaa Raspberry Pi, kaas oo saf ugu geli doona oo ku soo bandhigi doona bogga HTML.
Muhiim: Xadka dhererka fariimaha qoraalka ah ee Ruushku waa 58 xaraf (oo ay ku jiraan meelo bannaan). Haddii fariintu dheeraato, waa la gooyn doonaa inta lagu jiro gudbinta. Dhammaan xarfaha gaarka ah ayaa sidoo kale laga saari doonaa qoraalka, sida: /+$%&;''""<>n iyo wixii la mid ah.
Maadaama Raspberry Pi uu leeyahay hal deked oo UART ah, waxaanu ku xidhi doonaa modem-ka dayax-gacmeedka iyada oo loo marayo xarun dhexe, kaas oo xogta ka ururin doona modem-ka una diri doona Raspberry Pi.
modem raadiyaha
Adeegaha shabakadu kaliya kuma soo bandhigi doono dhammaan fariimaha lagaa helay shaashadda laakiin sidoo kale u gudbin doonaa Earth iyada oo loo marayo modem raadiyaha LoRa. Tani waa sida aan rabno in aan u tijaabino fikradda ka qaybinta internetka ee stratosphere (qadarinta mashruuca Google Loon). Dabcan, buufinteena stratospheric ma aha isgaarsiin dhamaystiran oo ku celis ah, laakiin xitaa haddii awooddeeda ay ku filan tahay gudbinta xogta deggan iyada oo aan la helin xogta muhiimka ah, nidaamyada khaaska ah ayaa hubaal ah inay awood u yeelan doonaan inay wax ka qabtaan qaybinta internetka ee hore.
Telemetry
Waxaan sidoo kale qorsheyneynaa inaan ku soo bandhigno xogta telemetry isla bogga HTML. Raspberry Pi wuxuu ka heli doonaa maamule duuleedka oo gooni ah.
Waxay codaynaysaa dareemayaasha kala duwan, kuwaas oo la dhigi karo gudaha iyo dibaddaba xayndaabka qalabka, ururinta xogta, habaynta, oo u gudbisa qaab ku habboon kuwa codsanaya. Xaaladeena, waxay codsan doontaa Raspberry Pi. Waxaan duubi doonaa cadaadiska, joogga, isku-duwayaasha GPS-ka, xawaaraha toosan iyo kan jiifka, iyo heerkulka.
Xogta ka timi hagaha duulimaadka waxa lagu kala qaadaa xadhkaha dhaadheer, kuwaas oo lagu farsameeyo isticmaalka summadan:
$str = 'N:647;T:10m55s;MP.Stage:0;MP.Alt:49;MP.VSpeed:0.0;MP.AvgVSpeed:0.0;Baro.Press:1007.06;Baro.Alt:50;Baro.Temp:35.93;GPS.Coord:N56d43m23s,E37d55m68s;GPS.Home:N56d43m23s,E37d55m68s;Dst:5;GPS.HSpeed:0;GPS.Course:357;GPS.Time:11h17m40s;GPS.Date:30.07.2018;DS.Temp:[fc]=33.56;Volt:5.19,0.00,0.00,0.00,0.00,0.00,0.00,0.00';
parse_str(strtr($str, [
':' => '=',
';' => '&'
]), $result);
print_r($result);waxaa loo rogaa soo diyaari qaab ku habboon in la soo bandhigo:

)Waxaan sidoo kale u gudbin doonaa xogta telemetry Dhulka oo ay la socdaan fariimahaaga. Ujeedadan awgeed, waxaanu geyn doonaa goob qaabilaada goobta la bilaabayo.
Bandhig iyo kamarad
Si loo hubiyo in server-ku uu dhab ahaantii ku helayo farriimahaaga satalaytka, iyo in ay dhab ahaantii ku jirto stratosphere oo aan ku fadhiyin xafiiskayaga, waxaanu go'aansanay inaan ku soo bandhigno dhammaan fariimaha telemetry ee bandhigga uu qabtay GoPro. Waxaan haysanay waqti yar oo aan ku diyaarino mashruuca (iyo goorma ayaa waligeed waqti ku filan?!), Markaa waxaan iska iloobin dhibkii AliExpress iyo birta alxanka, bedelkeeda waxaan dooranay qalab diyaarsan. Waa wax aad ugu filan baahidayada. Waxaan ku xidhi doonaa bandhiga Raspberry Pi anagoo adeegsanayna HDMI.
Waxaan sidoo kale qorsheyneynaa inaan ka sii deyno fiidiyowga GoPro anagoo adeegsanayna kanaal raadiye gaar ah, laakiin sida uu u shaqeyn doono wali lama garanayo - daboolka daruuriga hoose wuxuu si weyn u yareyn karaa kala duwanaanshaha isgaarsiinta. Si kastaba ha noqotee, ka dib markaan helno buufinta soo degtay, waxaan ka dhejin doonaa muuqaalka kamarada, waxaadna awoodi doontaa inaad naftaada aragto fariimahayaga "xarunta xogta ka hor inta aan la gaarin" iyo inta ay gaarsiisan tahay - telemetry waxaa lagu soo bandhigi doonaa isla bogga HTML, iyo qayb ka mid ah muraayadda ayaa muuqan doonta.
Питание
Dhammaan quruxdan waxaa ku shaqayn doona batari 3S4B lithium-saddex taxane ah iyo afar is barbar socda. Awoodda wadarta waxay ku dhowdahay 14 Ah at 12 V. Waxaan ku qiyaaseynaa in tani ay tahay mid ku filan, laakiin ka dib kulanka ugu dambeeya, waxaan, dabcan, cabbiri doonaa isticmaalka dhabta ah oo ku dar batari dheeraad ah haddii loo baahdo.
Ku dar dhammaan calaamadaha GPS-ka, kuwaas oo aan u isticmaali doono si aan u helno buufinka degay. Xerada hermetic waxay u adeegi doontaa sidii "guri" serverka iyo qalabka kale.
Waxay ka ilaalin doontaa qalabka jilicsan heerkulka iyo isbeddelka cadaadiska. Waxay sidoo kale hoos u dhigi doontaa qiyaasta shucaaca, inkastoo tani aysan khusayn mashruucayaga; Server-ku kuma duulayo stratosphere muddo aad u dheer, shucaaca asalka ahi ma aha mid u sarreeya sida ISS-ta.
Waxa intaa dheer in fariimaha loo diro , waxaad ka qayb qaadan kartaa tartan oo waxaad qiyaasi kartaa goobta baaritaanka. Abaalmarinta weyni waa safar lagu tagayo Baikonur si loo soo saaro dayax gacmeedka Soyuz-MS-13.
