Fiber Optic Gyroscope - Tus coj ntawm Modern Navigation.
Mar 30, 2018| Tam sim no txoj hauj lwm ntawm fiber optic gyro nyob rau hauv lub tshav pob ntawm inertial technology tau tsim thiab maj tsim mus rau hauv ib qho ntawm cov twj paj nruag mainstar ntawm inertial navigation. Tuam Tshoj kuj tau sau nws ua ib qho ntawm cov tseem ceeb technologies hauv lub tshav pob ntawm kev siv tshuab hluav taws xob. Hauv kev siv engineering, fiber optic gyroscope yog siv los rau kev qhia txog kev sib ntaus sib tua tactical, kev txav chaw txav ntawm tus cwj pwm, satellite positioning thiab precision spacecraft.
Lub hauv paus ntawm gyroscope yog tias thaum tus kwv yog tig ntawm kev kub ceev, lub siab lub zog yog loj heev, thiab lub axis ntawm kev sib hloov yuav ib txwm yuav ruaj taw mus rau qhov ntawm ib qho kev coj, thiab kev coj ua kev coj ua. Cov tsoos hnyuv pliav no yog hais txog cov neeg ua khoom ua si, cov neeg ua khoom ua si muaj lub siab xav tau rau cov txheej txheem, tus qauv yog txoj, thiab nws cov lus kom meej yog txwv los ntawm ntau yam. Txij li thaum xyoo 1970, txoj kev loj hlob ntawm cov khoom siv niaj hnub no tau nkag mus rau ib theem tshiab. Vali txo nws hwj mus rau cov tswv yim tshiab ntawm cov khoom siv fiber ntau ntawm gyroscope, xws li nyob rau hauv eighty s, kev tsim kho cov niaj hnub siv fiber ntau gyroscope tau txais sai heev, vim hais tias qhov fiber optic gyroscope muaj compact qauv, siab rhiab, kev lag luam txhim kho thiab zoo li ntawd, yog li cov fiber ntau optic gyroscope nyob rau hauv ntau qhov chaw tau hloov tag nrho cov neeg kho tshuab gyroscope, ua lub cim tseem ceeb ntawm cov cuab yeej navigation niaj hnub.
Raws li fiber ntau optic gyro angular rate dynamic environment, koj tuaj yeem pom tias yuav tsum muaj kev tuag ntawm fiber optic gyroscope cheeb tsam, kev taug kev mus, misalignment Angle, zero, scale factor, tshwj xeeb tshaj yog cov me angular tus nqi ntawm cov ntsuas yog ntsuas kom zoo. Fiber optic gyroscope nyob rau hauv hnyav ib puag ncig thiab muaj zog vibration dynamic siab nyob rau hauv qhov chaw tso zis drift yog ib qho ntawm qhov yuam kev loj, yuav tsum tau ua tib zoo tsim thiab ntsuam xyuas hauv av, coj kev ntsuas kom tshem tawm qhov yuam kev. Tsis tas li ntawd, thaum tus qauv loj thiab kev siv hluav taws xob muaj txaus redundancy, qhov kev xaiv ntawm kev tswj kev kub tswj tau hloov qhov qauv nyuaj thiab kev ua algorithm thiab txo cov teeb meem ntawm cov khoom calibration. Rau ntawm qhov no, nws tuaj yeem tua cov suab nrov thiab qhov kev hloov hauv lub cev qhov hluav taws xob thiab txhim kho cov kev ua tiav kev sib txuam nrog kev sib txuam nrog kev sib tw los ntawm kev ntxiv cov khoom siv thiab khoom sib nqus shielding rau lub gyroscope thiab lub cev ua ke.
Cov yam ntxwv ntawm fiber ntau optic gyroscope yog raws li lub hauv paus ntsiab lus ntawm kho qhov cuam tshuam, uas muaj tag nrho cov qauv hauv lub xeev, uas muaj cov yam ntxwv ntawm lub teeb me me, siab precision, yoojyim pib, dav bandwidth thiab ruaj ntseg ntev kev ua tau zoo. Nyob rau hauv daim ntawv thov txheej txheem, cov qauv no ruaj khov thiab tiv taus rau tej yam; Siab rhiab heev thiab kev daws teeb meem; Dynamic ntau yog tsis tshua muaj dav; Lub neej ntev, ruaj ntseg thiab txhim khu kev qha teeb liab.
Txoj kev loj hlob ntawm fiber ntau-optic gyro yog hloov sai heev. Muaj ntau lub tuam txhab loj tshaj plaws koom nrog kev tshawb nrhiav thiab kev tsim kho rau kev cia siab ntawm lawv txoj kev ua lag luam. Txij li thaum daim ntawv thov fib fib optic gyro zoo tagnrho hauv cov cab kuj thiab cov tub rog, cov tub rog ntawm txhua lub teb chaws tau nqis peev ntau thiab siv zog.
