SpaceX e sebelisa Linux le li-processor tse tloaelehileng tsa x86 ho Falcon 9

E hatisitsoe pokello ea tlhahisoleseding e mabapi le software e sebelisoang roketeng Falcon 9, e ipapisitse le lintlha tse ling tse boletsoeng ke basebetsi ba SpaceX lipuisanong tse fapaneng:

• Sistimi ea Falcon 9 ea onboard e sebelisa e hlobotsoeng
  Linux le likhomphutha tse tharo tse sa sebetseng tse ipapisitseng le li-processor tsa dual-core x86 tse tloaelehileng. Tšebeliso ea li-chips tse khethehileng tse nang le tšireletso e khethehileng ea mahlaseli bakeng sa lik'homphieutha tsa Falcon 9 ha li hlokehe, kaha sethaleng sa pele se khutlisitsoeng ha se qete nako e telele sepakapakeng le tsamaiso ea redundancy e lekane.

  Ke chip efe e khethehileng e sebelisoang ho Falcon 9 e sa tlalehoang, empa tšebeliso ea li-CPU tse tloaelehileng ke tloaelo e tloaelehileng, mohlala, ho laola multiplexer le demultiplexer (C & C MDM) ea International Space Station e ne e le qalong. hlometse CPU Intel 80386SX 20 MHz, 'me mosebetsing oa letsatsi le letsatsi ho ISS re sebelisa lilaptop tsa HP ZBook 15s tse nang le Debian Linux, Scientific Linux kapa Windows 10. Litsamaiso tsa Linux li sebelisoa e le li-terminals tse hole tsa C&C MDM, 'me Windows e sebelisetsoa ho bala lengolo-tsoibila, ho bala Web le boithabiso.

• Software ea taolo ea sefofane ea Falcon 9 e ngotsoe ka C/C++ 'me e tsamaisana ka ho bapa ho e 'ngoe le e 'ngoe ea likhomphutha tse tharo. Likhomphutha tse tharo tse sa sebetseng lia hlokahala ho etsa bonnete ba boemo bo nepahetseng ba ho tšepahala ka ho fokotsa mesebetsi e mengata. Sephetho sa qeto e 'ngoe le e' ngoe se bapisoa le sephetho se fumanoang lik'homphieutheng tse ling, 'me hafeela ho e-na le papali ho li-node tsohle tse tharo, taelo e amoheloa ke microcontroller e laolang li-motor le li-rudders tsa lattice.

  Taelo e amoheloa ke microcontroller haeba e amoheloa ka likopi tse tharo tse tšoanang, ho seng joalo taelo ea ho qetela e nepahetseng e etsoa. Haeba ho hloleha ha chip ho phetoa kapa litaelo ha li sa hlahisoa, joale chip e qala ho hlokomolohuoa 'me tsamaiso e sebetsa lik'homphieutha tse ling, haeba ho e-na le ho se lumellane ha lipalo moo mosebetsi o tsosolositsoeng ho fihlela sephetho se lumellana. Ha ho ka etsahala hore k'homphieutha e hlolehe, sefofane se ka phethoa ka katleho haeba bonyane ho na le tsamaiso e le 'ngoe e tsoelang pele ho sebetsa.

• Software e khethehileng bakeng sa Sistimi ea Falcon 9 ka holim'a board, simulator ea rocket, lisebelisoa tsa tlhahlobo ea khoutu ea sefofane, khoutu ea likhokahano le software ea tlhahlobo ea sefofane ho tsoa litsing tsa fatše. ntshetswa pele sehlopha sa batho ba ka bang 35.
• Pele ho qala ts'ebetso ea 'nete, lisebelisoa tsa taolo ea sefofane le hardware li lekoa ka har'a simulator, e etsisang maemo a fapaneng a sefofane le maemo a tšohanyetso.
• The Crew Dragon e tsamaisang sepakapaka se tsamaisoang ka har'a orbit e boetse e sebelisa Linux le software ea sefofane ho C ++. Sehokelo seo bo-astronote ba sebetsang ka sona se kengoa tšebetsong se ipapisitse le sesebelisoa sa webo sa JavaScript se buloang ho Chromium. Taolo e etsoa ka skrine ea ho ama, empa haeba e ka hloleha fumaneha le konopo ea konopo ho laola sepakapaka.
