Ngomso siya kuthumela iseva yethu kwi-stratosphere. Ngethuba lokuhamba, ibhaluni ye-stratospheric iya kusasaza i-Intanethi, idubule kwaye isasaze idatha yevidiyo kunye ne-telemetry emhlabeni. Sibhale amaxesha amaninzi ukuba siza kuthetha ngecala lobugcisa beprojekthi yethu "IZiko leDatha yeNdawo" (eyayiphendulwa ngaphambili kwigama elithi ""). Sathembisa - siyayifeza! Ngaphantsi kokusikwa kukho iinqununu ze-hardware kunye nekhowudi.
umncedisi wewebhu
Nakwiprojekthi yangaphambili ethi "Umncedisi kumafu", xa sinyuka kwibhaluni epheleleyo kunye neqela labantu ababini, sithatha kunye nathi umncedisi ogcweleyo kunye nendibano yebhetri, masithi, kungekhona ingqiqo. Kwaye ngoku sithetha ngebhaluni encinci ye-stratospheric, eya kufuneka inyuke i-30 km, kungekhona i-1. Ngoko ke, sakhetha i-Raspberry Pi efanayo njengomncedisi wewebhu. Le microcomputer izakuvelisa iphepha leHTML kwaye ilibonise kumboniso owahlukileyo.
Uqhagamshelwano lwesathelayithi
Ukongeza kwi-Raspberry, iimodem ezivela kwi-Iridium kunye ne-Globalstar yonxibelelwano lwe-satellite yonxibelelwano ziya kubhabha kwibhodi. Njengoko ukhumbula, sicebe ukongeza imodem yenethiwekhi yeGonets yasekhaya kwinkampani yabo, kodwa besingenaxesha lokuyifumana kwangaphambili, siya kuyithumela kwinqwelomoya elandelayo. Ngemodem yesathelayithi, iseva yewebhu iya kufumana imiyalezo yakho, enokuthunyelwa kuyo . Le miyalezo iya kuthunyelwa kwi-Raspberry Pi, eya kufola kwaye ibonise kwiphepha le-HTML.
Inqaku elibalulekileyo: umda kubude bomyalezo wombhalo ngesiRashiya ngamagama angama-58 (kubandakanywa nezikhala). Ukuba umyalezo mde, uya kunqunyulwa ngexesha logqithiso. Kwakhona, bonke abalinganiswa abakhethekileyo baya kusikwa kwisicatshulwa, umzekelo, /+$%&;''""<>n kunye nokunye.
Ekubeni i-Raspberry Pi ine-port enye ye-UART, siya kudibanisa iimodem zesathelayithi ngokusebenzisa i-hub ephakathi, eya kuqokelela idatha kwiimodem kwaye iyithumele kwi-Raspberry Pi.
Imodem yerediyo
Umncedisi wewebhu akayi kubonisa kuphela yonke imiyalezo efunyenwe kuwe kwisiboniso, kodwa kwakhona ukuyihambisa eMhlabeni ngemodem yerediyo ye-LoRa. Ke sifuna ukuvavanya umbono wokusasaza i-Intanethi ukusuka kwistratosphere (imbeko kwiprojekthi kaGoogle Loon). Kakade ke, ibhaluni yethu ye-stratospheric ayikho into ephindaphindayo yonxibelelwano yonxibelelwano, kodwa nokuba izakhono zayo zanele ukuhanjiswa kwedatha ezinzileyo, ngaphandle kwelahleko enkulu yolwazi, ngoko ke iinkqubo ezikhethekileyo ziya kuhlangabezana nokusasazwa kwe-Intanethi ukusuka kwindawo yangaphambili.
I-Telemetry
Ukongeza, siceba ukubonisa idatha ye-telemetry kwiphepha elifanayo le-HTML. I-Raspberry Pi iya kubathatha kumlawuli wendiza eyahlukileyo.
Iphanda abenzi boluvo abahlukeneyo abanokubekwa ngaphakathi nangaphandle kwebhokisi ye-hermetic ye-hardware, iqokelela ulwazi kwimfumba, idibanise kwaye inike ngendlela efanelekileyo kwabo babuzayo. Kwimeko yethu, iya kucela iRaspberry Pi. Siza kurekhoda uxinzelelo, ukuphakama, ulungelelwaniso lweGPS, isantya esithe nkqo nesithe tyaba kunye nobushushu.
Idatha esuka kumlawuli wenqwelomoya ihanjiswa ngemigca emide, ethi ke, kusetyenziswa le khowudi:
$str = 'N:647;T:10m55s;MP.Stage:0;MP.Alt:49;MP.VSpeed:0.0;MP.AvgVSpeed:0.0;Baro.Press:1007.06;Baro.Alt:50;Baro.Temp:35.93;GPS.Coord:N56d43m23s,E37d55m68s;GPS.Home:N56d43m23s,E37d55m68s;Dst:5;GPS.HSpeed:0;GPS.Course:357;GPS.Time:11h17m40s;GPS.Date:30.07.2018;DS.Temp:[fc]=33.56;Volt:5.19,0.00,0.00,0.00,0.00,0.00,0.00,0.00';
parse_str(strtr($str, [
':' => '=',
';' => '&'
]), $result);
print_r($result);Jika ube luluhlu ngendlela elungele umboniso:
Array
(
[N] => 647
[Т] => 10m55з
[MP_Stage] => 0
[MP_Alt] => 49
[MP_VSpeed) => 0.0
[MP_AvgVSpeed] => 0.0
[Baro Рrеss] => 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] => [fс] ЗЗ.56
[Volt] => 5.19, 0.00,0.00,0.00,0.00,0.00,0.00,0.00
)Siza kusasaza idatha yetelemetry kuMhlaba kunye nemiyalezo yakho. Ukwenza oku, siya kuthumela isikhululo sokwamkela kwindawo yophehlelelo.
Umboniso kunye nekhamera
Ukuze uqinisekise ukuba umncedisi ufumana imiyalezo yakho ngonxibelelwano lwesathelayithi, kwaye eneneni iye yabhabhela kwi-stratosphere kwaye ayimi kwiofisi yethu, sigqibe kwelokuba sibonise yonke imiyalezo nge-telemetry kumboniso oza kubanjwa. iGoPro. Kwakukho ixesha elincinane lokulungiselela iprojekthi (inokubakho njani into eninzi ?!), Ngoko asizange sikhathazeke nge-Aliexpress kunye nentsimbi ye-soldering, kodwa endaweni yoko sathatha isixhobo esele silungile. Yanele kwiimfuno zethu. Siza kudibanisa umboniso kwiRaspberry nge-HDMI.
Sikwaceba ukusasaza ividiyo esuka kwiGoPro ngejelo likanomathotholo elahlukileyo, kodwa indlela eza kusebenza ngayo ayaziwa-mhlawumbi amafu aphantsi aya kulunciphisa kakhulu uluhlu lonxibelelwano. Kodwa kuyo nayiphi na imeko, emva kokuba sifumene ibhaluni ye-stratospheric, siya kuthumela ividiyo esuka kwikhamera kwaye unokuzibonela ngokwakho ukuba yeyiphi imiyalezo "indawo yethu yedatha yangaphambili" efunyenweyo kunye nokuba inyuke kangakanani na - i-telemetry iya kuboniswa. kwiphepha elifanayo le-HTML, Ukongeza, iqhekeza le-horizon liza kubonakala.
Ukunikezelwa kwamandla
Bonke ubuhle obuchazwe ngasentla buya kunikwa amandla yindibano yeebhetri ze-lithium ezihlanganiswe ngokwesekethe ye-3S4B - ezintathu kwiichungechunge, ezine ngokufana. Umthamo opheleleyo malunga ne-14 Ah kwi-voltage ye-12 V. Ngokutsho koqikelelo lwethu, oku kufuneka kube ngokwaneleyo, kodwa emva kwendibano yokugqibela, ngokuqinisekileyo, siya kulinganisa ukusetyenziswa kwangempela, kwaye ukuba kuyimfuneko, yongeza iibhetri ezininzi.
Yongeza kuzo zonke ezi bhakhoni zeGPS, esiza kuzisebenzisa ukukhangela ibhaluni yestratospheric. Kwaye ibhokisi ye-hermetic iya kuba "yindlu" yomncedisi kunye nezinye izixhobo.
Iya kukhusela izixhobo ezibuthathaka kubushushu kunye notshintsho loxinzelelo. Kwangaxeshanye, iya kunciphisa idosi yemitha, nangona oku kungadlali nayiphi na indima kwiprojekthi yethu, umncedisi uya kubhabha kwi-stratosphere ixesha elifutshane kakhulu, kwaye imvelaphi ayikho phezulu njenge-ISS.
Ukongeza kokuthumela imiyalezo kwi , unokuthatha inxaxheba kukhuphiswano kwaye uqikelele ukuba uphononongo luya kuhlala phi. Elona bhaso liphambili luhambo oluya e-Baikonur kuphehlelelo lwe-Soyuz-MS-13 yesiphekepheke esiphathwayo.
