Isixokelelwano sokuhamba ngendlela echanekileyo sesona sixhobo siphambili solawulo lokuhamba ngenqwelomoya kunye nohlaselo oluchanekileyo lwenkqubo yayo yezixhobo.Izikimu zayo eziphambili ziquka izikimu zeplatifomu kunye nezicwangciso ze-strapdown.Ngophuhliso lweteknoloji ye-inertial ye-strapdown kunye ne-optical gyro, i-strapdown isetyenziswe ngokubanzi kwintsimi ye-airborne kunye neenzuzo zayo zokuthembeka okuphezulu, ukukhanya kunye nobukhulu obuncinci, ukusetyenziswa kwamandla aphantsi kunye neendleko eziphantsi.[1-4].Okwangoku, inkqubo yokukhangela i-airborne strapdown navigation system iyindibaniselwano ye-laser gyro strapdown navigation system kunye ne-fiber optic gyro strapdown navigation system.Phakathi kwabo, i-LN-100G ye-Northrop Grumman, i-Honeywell's H-764G laser gyro strapdown navigation system kunye ne-Northrop ye-fiber Grum2 '1 I-optic gyro strapdown navigation system isetyenziswe ngokubanzi kwiinqwelomoya zokulwa zaseMelika[1]I-Northrop Grumman Inkampani iphuhlise inkqubo ye-LN-251 yokuhamba ngenqwelo-ntaka kunye nophawu olubalulekileyo lwe-fiber optic gyro echanekileyo, kwaye emva koko yaphuhlisa i-LN-260 ukuze ivumelane nokuhamba kweenqwelo-moya. I-LN-260 yakhethwa yi-US Air Force ukuze Ukuphuculwa kwe-avionics ye-F-16 yeenqwelo zamazwe ngamazwe zokulwa. Impazamo yesantya se-eastbound ye-2.43ft/s (RMS) kwindawo eguquguqukayo kakhulu.Ngoko ke, inkqubo ye-optical strapdown inertial navigation system inokuhlangabezana ngokupheleleyo neemfuno zokusebenza kwenqwelomoya ngokwendlela yokuhamba kunye nobuchule bokukhokela.[1].
Xa kuthelekiswa ne-laser gyro strapdown navigation system, i-fiber optic gyro strapdown navigation system inezi ngenelo zilandelayo: 1) ayifuni jitter yoomatshini, yenza lula ulwakhiwo lwenkqubo kunye nobunzima boyilo lokunciphisa ukungcangcazela, inciphisa ubunzima kunye nokusetyenziswa kwamandla, kwaye iphucula amandla ombane. ukuthembeka kwenkqubo yokukhangela; 2) Ukuchaneka kombala wefiber optic gyro igubungela inqanaba lobuchule ukuya kwinqanaba lobuchule, kwaye inkqubo yayo yokukhangela ehambelana nayo inokwenza inkqubo yokukhangela ehambelanayo, egubungela yonke into ukusuka kwisimo sengqondo ukuya kwinkqubo yokukhangela kumgama omde- inqwelomoya yokunyamezela;3) Umthamo wefiber optic gyroscope ngokuthe ngqo uxhomekeke kubungakanani beringi yefiber.Ngokusetyenziswa okuvuthiweyo kwefayibha yedayamitha ecolekileyo, umthamo wefiber optic gyroscope ngokuchaneka okufanayo uya usiba mncinci kwaye uncinci, kwaye uphuhliso lokukhanya kunye neminiaturization yinto engenakuthintelwa.
Iskimu soyilo ngokubanzi
I-fiber optic gyro strapdown navigation system ye-airborne iqwalasela ngokupheleleyo inkqubo yokutshatyalaliswa kobushushu kunye nokwahlukana kwe-photoelectric, kwaye yamkele "i-three-cavity" scheme.[6,7], kubandakanywa nomgodi we-IMU, umgodi we-elektroniki kunye nomgodi wamandla wesibini.Umngxuma we-IMU uqulathe ulwakhiwo lomzimba we-IMU, iringi ye-fiber sensing kunye ne-quartz flexible accelerometer (iquartz plus meter); Umngxuma wombane unebhokisi ye-gyro photoelectric, ibhodi yokuguqula iimitha, ikhompyutha yokukhangela kunye nebhodi yojongano, kunye nesikhokelo sococeko. ibhodi;Umgodi wamandla wesibini ubandakanya imodyuli yamandla esibini epakishweyo, isihluzo se-EMI, i-capacitor yokukhupha intlawulo.Ibhokisi ye-gyro photoelectric kunye neringi yefiber optical kumngxuma we-IMU kunye zenza icandelo le-gyro, kunye ne-quartz eguquguqukayo ye-accelerometer kunye nepleyiti yokuguqula iimitha. kunye zenza icandelo le-accelerometer[8].
Iskimu esipheleleyo sigxininisa ukuhlukana kwamacandelo e-photoelectric kunye noyilo lwemodyuli yecandelo ngalinye, kunye noyilo oluhlukeneyo lwenkqubo ye-optical system kunye nenkqubo yesekethe yokuqinisekisa ukutshatyalaliswa kobushushu kunye nokunyanzeliswa kokuphazamiseka komnqamlezo. imveliso, izixhumi zisetyenziselwa ukudibanisa iibhodi zeesekethe kwigumbi le-elektroniki, kwaye i-fiber optical ring kunye ne-accelerometer kwigumbi le-IMU zichithwa ngokulandelanayo.Emva kokwenza i-IMU, yonke indibano iqhutywa.
Ibhodi yesekethe kumgodi we-elektroniki yibhokisi ye-gyro photoelectric ukusuka phezulu ukuya ezantsi, kubandakanywa nomthombo wokukhanya we-gyro, umtshina kunye nesekethe yokukhupha ngaphambili; Ibhodi yokuguqula itafile igqibezela ukuguqulwa kwesiginali ye-accelerometer yangoku kwisignali yedijithali; Isisombululo sokuNavigation kunye Isekethe yojongano ibandakanya ibhodi yojongano kunye nebhodi yesisombululo sokukhangela, ibhodi yojongano igqibezela ukufunyanwa okuhambelanayo kwedatha yesixhobo esine-inertial yamajelo amaninzi, ukusebenzisana kombane kunye nonxibelelwano lwangaphandle, ibhodi yesisombululo sokukhangela ubukhulu becala igqibezela ukujongwa okusulungekileyo kunye nesisombululo esidibeneyo sokukhangela; Ibhodi yesikhokelo igqibezela ubukhulu becala i-satellite navigation, kwaye ithumela ulwazi kwibhodi yesisombululo sokuhamba kunye nebhodi ye-interface ukugqiba ukuhamba okudibeneyo.Umbane wesibini kunye nesekethe ye-interface ixhunyiwe ngekhonkco, kwaye ibhodi yesiphaluka idibaniswe ngekhonkco.
Iiteknoloji eziphambili
1. Iskimu soyilo oludibeneyo
I-airborne fiber optic gyro navigation system iqonda iidigri ezintandathu ze-aircraft of freedom motion discovery ngokudityaniswa kwezinzwa ezininzi.I-Three axis gyro kunye ne-axis accelerometer emithathu inokuqwalaselwa kuyilo oluphezulu lokudityaniswa, ukunciphisa ukusetyenziswa kwamandla, umthamo kunye nobunzima.Ukwenzela i-fiber optic. icandelo le-gyro, inokwabelana ngomthombo wokukhanya ukwenza uyilo lokudityaniswa kwe-axis ezintathu; Kwicandelo le-accelerometer, i-quartz flexible accelerometer isetyenziswa ngokubanzi, kwaye isekethe yokuguqula inokuyilwa ngeendlela ezintathu kuphela.Kukwakho ingxaki yexesha. ungqamaniso ekufumaneni idatha yeenzwa ezininzi.Ukuhlaziywa kwesimo sengqondo esiguqukayo, ukuhambelana kwexesha kunokuqinisekisa ukuchaneka kohlaziyo lwesimo sengqondo.
2. Uyilo lokuhlukana kweefoto zombane
I-fiber optic gyro iyinzwa ye-fiber optic esekelwe kwimpembelelo ye-Sagnac yokulinganisa i-angular rate.Phakathi kwabo, i-fiber ring iyona nxalenye ephambili yesantya esibucayi se-angular ye-fiber gyroscope.Ingxwelerheka ngamakhulu aliqela eemitha ukuya kumawaka aliqela eemitha zefayibha.Ukuba intsimi yobushushu yefiber optical ring iyatshintsha, iqondo lobushushu kwinqanaba ngalinye lefiber optical ring liyatshintsha ngokuhamba kwexesha, kwaye imiqadi emibini yokukhanya idlula kwindawo. ngamaxesha ahlukeneyo (ngaphandle kwendawo ephakathi kwekhoyili ye-fiber optical), bafumana iindlela ezahlukeneyo ze-optical, okubangelwa ukuhlukana kwesigaba, olu tshintsho lwesigaba esingatshintshiyo alubonakali ukusuka kwisigaba seSagneke esibangelwa ukujikeleza.Ukuze kuphuculwe izinga lokushisa ukusebenza kwe-fiber optic gyroscope, eyona nxalenye ye-gyroscope, i-fiber ring, kufuneka igcinwe kude nomthombo wobushushu.
Kwi-gyroscope edibeneyo ye-photoelectric, izixhobo ze-photoelectric kunye neebhodi zeesekethe ze-gyroscope zisondele kwindandatho ye-fiber optical.Xa isivamvo sisebenza, iqondo lobushushu lesixhobo ngokwalo liya kunyuka ukusa kumlinganiselo othile, kwaye lichaphazele isangqa sefiber optical ngokusebenzisa imisebe kunye ne-conduction. i-gyroscope ye-fiber optical, kubandakanywa nesakhiwo sendlela ye-optical kunye nesakhiwo sesekethe, iintlobo ezimbini zesakhiwo sokuhlukana okuzimeleyo, phakathi kwefiber kunye ne-waveguide line connection.Kuphephe ubushushu obuvela kwibhokisi yomthombo wokukhanya echaphazela i-fiber heat transfer sensitivity.
3. Uyilo lokuzifumanisa ngamandla
I-Fiber optic gyro strapdown navigation system idinga ukuba nombane wokuzivavanya umsebenzi wokuzivavanya kwisixhobo esinertial.Ngenxa yokuba inkqubo yokukhangela ithatha ufakelo olusulungekileyo lwe-strapdown ngaphandle kwe-transposition mechanism, uvavanyo lokuzivavanya lwezixhobo ezingenayo lugqitywe ngomlinganiselo we-static kwiindawo ezimbini, ezizezi. , ukuvavanywa kwenqanaba lesixhobo kunye nokuzivavanya kwenqanaba lenkqubo, ngaphandle kwe-excitation yangaphandle yokuguqula.
