Mazuva mashoma apfuura ruzivo rwakaburitswa nezve muunganidzwa wedata unoburitsa mhando yesoftware uye Hardware iyo inoshandiswa muSpaceX, masisitimu anoshanda anoshandiswa muFalcon 9 roketi kune mhando yehardware inoshandiswa. Ruzivo urwu rwese rwakavakirwa pazvikamu zvakataurwa nevashandi veSpaceX muhurukuro dzakasiyana.
Saka nekudaro, mukati meruzivo rwakaziviswa Izvo zvinotaurwa kuti iyo Falcon 9 yakadzamidzirwa masisitimu anoshandisa akareruka Linux y matatu makopi emakomputa zvichibva pane zvakajairwa processor yemhuri hunyambiri musimboti x86.
Pamusoro pekuti mukati memidziyo inoshandiswa, kushandiswa kwehunyanzvi machipisi hakudiwe neakakosha radiation yekudzivirira kweFalcon 9 makomputa, sezvo yekutanga yekudzoka nhanho isiri munzvimbo yekunze kwenguva yakareba uye kudzikiswa kwemaitiro kwakaringana.
Chikamu icho chisina kuziviswa pachacho, ndechekuti ndeipi chip chaiyo inoshandiswa mu Falcon 9, asi kushandiswa kweyakajairwa CPU kwakajairika tsika, semuenzaniso, iyo Intel 80386SX 20 MHz CPU yakatanga kugadzirirwa neInternational Space Station control multiplexer uye demultiplexer (C&C MDM) uye HP ZBook mabhuku emabhuku anoshandiswa mukushanda kwezuva nezuva pa ISS 15s ine iyo "Debian" Linux kugoverwa, Sayenzi Linux kana Windows 10.
Kune maLinux masisitimu, iwo anoshandiswa semitunhu iri kure yeC & C MDM uye Windows ye leer maemail, kuvhura pawebhu uye kuvaraidza (Chokwadi chiri kuda kuziva, asi chinonzwisisika kana zvasvika pakudzivirira mapuratifomu makuru kubva kuanozivikanwa zvino "kukanganisa kwevanhu").
Kana ari Falcon 9 ndege yekudzora software yakanyorwa muC / C ++ uye inomhanya yakafanana pane imwe neimwe yemakomputa matatu.
Makomputa matatu asingadiwi anodikanwa kuti ave nechokwadi cheyero chaiyo yekuvimbika nekuda kwenzvimbo dzakawanda dzekuchengetedza. Mhedzisiro yesarudzo yega yega inofananidzwa nemhedzisiro inowanikwa mune mamwe makomputa, uye chete kana node nhatu dzichienderana, iwo murairo unogamuchirwa ne microcontroller iyo inodzora mota uye rattice rudders.
Nei ma processor matatu? Izvi zvinodaro nekuti, sezvakatsanangurwa muStackExchange Space Exploration, SpaceX inoshandisa iyo Actor-Mutongi system kupa chengetedzo kuburikidza ne redundancy. Mune ino sisitimu, nguva imwe neimwe sarudzo painotorwa, inofananidzwa nezvakabuda kune mamwe macores. Kana paine kusawirirana, sarudzo inoraswa uye maitiro acho anotangazve. Izvo chete kana processor yega yega ikawana mhinduro imwechete iyo murairo unotumirwa kune PowerPC microcontroller.
Aya madhairekita, ayo anoita sarudzo dzeroketi mota uye zvimbi pamambure, vanowana mirairo mitatu kubva kune yega yega maX86 processor. Kana tambo dzese nhatu dzakaenzana, ipapo microcontroller inoita rairo, asi kana imwe yevatatu isiriyo, mutungamiriri anotevera kuraira kwekupedzisira kuri pamusoro. Kana zvinhu zvikatadza kufamba zvakanaka, iyo Falcon 9 inofuratira mirairo kubva kune inokundikana chip.
Chikwata chinosanganisira vanhu makumi matatu nevashanu yakagadzira yakatarwa software yehurongwa mungarava Falcon 9, rocket simulator, zvishandiso zvekuyedza kodhi yekudzora ndege, kodhi yekutaurirana uye software yekuongorora ndege kubva pasi masisitimu.
Pamberi pekuburitswa chaiko kwesoftware yekudzora nendege, inoedzwa mune simulator, umo mamiriro akasiyana enendege nemamiriro ekukurumidzira zvinoenzaniswa.
Crew Dragon yakagadziriswa spacecraft yakaunzwa munzira yayo zvakare shandisa Linux uye C ++ ndege software. Iyo inowirirana maastronuts inoshanda nayo inoitwa pachishandiswa a Vhura webhu-based JavaScript application muChromium. Management iri kuburikidza neyekubata skrini, asi kana zvikakundikana pane zvakare keyboard yekudzora iyo spacecraft.
Chekupedzisira, kana iwe uchida kuziva zvakawanda nezve ruzivo rwakatorwa, unogona kubvunza yekutanga noti nekuenda kunotevera chinongedzo.
