I-Anatomy ye-"Space Data Center". Iseva ye-Sky-high: bheka ngaphansi kwe-hood

Kusasa sizothumela iseva yethu ku-stratosphere. Ngesikhathi sendiza, ibhaluni ye-stratospheric izosabalalisa i-inthanethi, ishuthe futhi idlulisele ividiyo nedatha ye-telemetry phansi. Sibhale izikhathi eziningana ukuthi sizokhuluma ngohlangothi lwezobuchwepheshe lwephrojekthi yethu "Isikhungo Sedatha Yendawo" (ngaphambilini siphendule igama elithi "Iseva emafini 2.0"). Sathembisa - siyaletha! Ngaphansi kokusikwa kukhona izingcezu ezimbalwa zehadiwe nekhodi.

iseva yewebhu

Ngisho nakuphrojekthi yangaphambilini ethi "Iseva Emafu", lapho sikhuphuka ngebhaluni eligcwele neqembu labantu ababili, ukuthatha nathi iseva egcwele ngokugcwele ngomhlangano webhethri, ake sithi, hhayi okunengqondo. Futhi manje sikhuluma ngebhaluni elincane le-stratospheric, okuzodingeka likhuphuke ngamakhilomitha angu-30, hhayi 1. Ngakho-ke, sikhethe i-Raspberry Pi efanayo njengeseva yewebhu. Le khompyutha encane izokhiqiza ikhasi le-HTML futhi ilibonise kusibonisi esihlukile.

Ukuxhumeka kwesathelayithi

Ngokungeziwe ku-Raspberry, amamodemu asuka kunethiwekhi yokuxhumana ngesathelayithi ye-Iridium ne-Globalstar azondiza ebhodini. Njengoba ukhumbula, sihlele ukungeza imodemu yenethiwekhi ye-Gonets yasekhaya enkampanini yabo, kodwa asibanga naso isikhathi sokuyithola kusengaphambili, ngakho-ke sizoyithumela endizeni elandelayo. Ngemodemu yesathelayithi, iseva yewebhu izothola imilayezo yakho, engathunyelwa kuyo ikhasi lephrojekthi. Le milayezo izodluliselwa ku-Raspberry Pi, ezoyibeka kulayini futhi iyibonise ekhasini le-HTML.

Iphuzu elibalulekile: umkhawulo wobude bomlayezo wombhalo ngesiRashiya yizinhlamvu ezingu-58 (kuhlanganise nezikhala). Uma umyalezo umude, uzonqanyulwa ngesikhathi sokudlulisa. Futhi, zonke izinhlamvu ezikhethekile zizosikwa embhalweni, isibonelo, /+$%&;''""<>n nokunye okunjalo.

Njengoba i-Raspberry Pi inembobo ye-UART eyodwa kuphela, sizoxhuma amamodemu wesathelayithi ngehabhu eliphakathi, elizoqoqa idatha kumamodemu bese liyithumela ku-Raspberry Pi.

Imodemu yomsakazo

Iseva yewebhu ngeke ibonise kuphela yonke imilayezo etholwe kuwe esibonisini, kodwa futhi izoyidlulisela Emhlabeni ngemodemu yomsakazo we-LoRa. Ngakho-ke sifuna ukuhlola umbono wokusabalalisa i-inthanethi kusuka ku-stratosphere (inkokhiso kuphrojekthi ye-Google Loon). Yiqiniso, ibhaluni yethu ye-stratospheric ayiyona into ephindaphindayo yokuxhumana egcwele, kodwa ngisho noma amakhono ayo anele ukudluliswa kwedatha ezinzile, ngaphandle kokulahlekelwa okukhulu kolwazi, khona-ke izinhlelo ezikhethekile zizobhekana nokusabalalisa i-intanethi kusuka endaweni yangaphambili.

I-Telemetry

Ngaphezu kwalokho, sihlela ukubonisa idatha ye-telemetry ekhasini elifanayo le-HTML. I-Raspberry Pi izozithatha kusilawuli sendiza esihlukile.

Iphenya izinzwa ezihlukahlukene ezingafakwa ngaphakathi nangaphandle kwebhokisi le-hermetic le-hardware, iqoqe ulwazi enqwabeni, ilihlanganise futhi inikeze ngendlela efanelekile kulabo ababuzayo. Esimweni sethu, izocela i-Raspberry Pi. Sizorekhoda ingcindezi, ukuphakama, izixhumanisi ze-GPS, isivinini esiqondile nesivundlile kanye nezinga lokushisa.

Idatha evela kusilawuli sendiza idluliswa ngemigqa emide, bese kusetshenziswa le khodi:

$str = 'N:647;T:10m55s;MP.Stage:0;MP.Alt:49;MP.VSpeed:0.0;MP.AvgVSpeed:0.0;Baro.Press:1007.06;Baro.Alt:50;Baro.Temp:35.93;GPS.Coord:N56d43m23s,E37d55m68s;GPS.Home:N56d43m23s,E37d55m68s;Dst:5;GPS.HSpeed:0;GPS.Course:357;GPS.Time:11h17m40s;GPS.Date:30.07.2018;DS.Temp:[fc]=33.56;Volt:5.19,0.00,0.00,0.00,0.00,0.00,0.00,0.00';
parse_str(strtr($str, [
	
':' => '=',
	
';' => '&'
]), $result);
print_r($result);

shintsha ube amalungu afanayo ngendlela elungele ukuboniswa:

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 
)

Futhi sizosakaza idatha ye-telemetry eMhlabeni kanye nemilayezo yakho. Ukwenza lokhu, sizosebenzisa isiteshi sokwamukela endaweni yokwethulwa.

Isibonisi nekhamera

Ukuze wenze isiqiniseko sokuthi iseva ithola imilayezo yakho ngesathelayithi, nokuthi indizele ku-stratosphere futhi ayimile ehhovisi lethu, sinqume ukubonisa yonke imilayezo nge-telemetry kusibonisi esizothathwa ngu. iGoPro. Kwakukhona isikhathi esincane sokulungiselela iphrojekthi (kungenzeka kanjani ukuthi kube khona okuningi?!), Ngakho-ke asizange sikhathazeke nge-Aliexpress kanye ne-soldering iron, kodwa esikhundleni salokho sathatha idivayisi esenziwe ngomumo. Kungaphezu kokwanele izidingo zethu. Sizoxhuma isibonisi kuRaspberry nge-HDMI.

Sihlela futhi ukusakaza ividiyo evela ku-GoPro ngesiteshi somsakazo esihlukile, kodwa ukuthi izosebenza kanjani akwaziwa - mhlawumbe amafu aphansi azonciphisa kakhulu ububanzi bokuxhumana. Kodwa kunoma yikuphi, ngemva kokuthola ibhaluni le-stratospheric elimisiwe, sizothumela ividiyo evela kukhamera futhi ungazibonela ngokwakho ukuthi yimiphi imilayezo "isikhungo sethu sedatha yangaphambi kwesikhala" esiyitholile nokuthi sikhuphukele kuliphi izinga - i-telemetry izoboniswa. ekhasini elifanayo le-HTML, Ngaphezu kwalokho, ucezu lomkhathizwe luzobonakala.

Питание

Bonke ubuhle obuchazwe ngenhla buzonikwa amandla ukuhlanganiswa kwamabhethri e-lithium ahlanganiswe ngokuvumelana nesekethe ye-3S4B - amathathu ochungechungeni, amane ngokuhambisana. Umthamo ophelele umayelana ne-14 Ah ku-voltage ye-12 V. Ngokwezilinganiso zethu, lokhu kufanele kube ngokwanele, kodwa ngemva komhlangano wokugcina, yiqiniso, sizokala ukusetshenziswa kwangempela, futhi uma kunesidingo, engeza amabhethri amaningi.

Engeza kuwo wonke lawa mabhakhoni e-GPS, esizowasebenzisa ukucinga ibhaluni ye-stratospheric ehlezi. Futhi ibhokisi le-hermetic lizoba "indlu" yeseva namanye amadivayisi.

Izovikela imishini ethambile ekushintsheni kwezinga lokushisa nokucindezela. Ngesikhathi esifanayo, izophinde inciphise umthamo wemisebe, nakuba lokhu kungadlali noma iyiphi indima kuphrojekthi yethu, iseva izondizela ku-stratosphere isikhathi esifushane kakhulu, futhi isizinda sakhona asiphezulu njengaku-ISS.

Ngaphezu kokuthumela imiyalezo ku iwebhusayithi yephrojekthi, ungabamba iqhaza emqhudelwaneni futhi uqagele ukuthi uphenyo luzofika kuphi. Umklomelo omkhulu uwuhambo oluya e-Baikonur lapho kwethulwa khona umkhumbi-mkhathi ophethwe umuntu i-Soyuz-MS-13.
