Nyob rau lub sijhawm ntawm kev siv tshuab tshiab, cov txheej txheem navigation tau tshwm sim ua lub hauv paus tseem ceeb, tsav ntau qhov kev nce qib, tshwj xeeb tshaj yog nyob rau hauv cov kev lag luam uas muaj kev ntsuas qhov tseeb. Txoj kev taug kev los ntawm kev tsav tsheb saum ntuj ceeb tsheej mus rau Inertial Navigation Systems (INS) uas muaj kev txawj ntse qhia txog tib neeg txoj kev siv zog rau kev tshawb nrhiav thiab kev ntsuas qhov tseeb. Qhov kev tshuaj xyuas no nkag mus tob rau hauv INS cov txheej txheem nyuaj, tshawb nrhiav cov thev naus laus zis tshiab ntawm Fiber Optic Gyroscopes (FOGs) thiab lub luag haujlwm tseem ceeb ntawm Polarization hauv Kev Tswj Xyuas Fiber Loops.
Ntu 1: Txhais Cov Txheej Txheem Inertial Navigation (INS):
Cov Tshuab Taw Qhia Kev Nkoj (Inertial Navigation Systems - INS) sawv tawm ua cov cuab yeej pab taw qhia uas tsis muaj neeg tswj, suav qhov chaw, kev taw qhia, thiab qhov ceev ntawm lub tsheb kom meej, tsis hais txog cov cim qhia sab nraud. Cov tshuab no sib haum xeeb cov cuab yeej txav mus los thiab kev tig, sib xyaw ua ke nrog cov qauv suav rau qhov ceev pib, qhov chaw, thiab kev taw qhia.
Ib qho INS archetypal muaj peb lub ntsiab lus tseem ceeb:
· Cov ntsuas kev nrawm: Cov ntsiab lus tseem ceeb no sau npe lub tsheb txoj kev nrawm nrawm, txhais cov kev txav mus los ua cov ntaub ntawv ntsuas tau.
· Gyroscopes: Ib qho tseem ceeb rau kev txiav txim siab qhov ceev ntawm lub kaum sab xis, cov khoom no yog qhov tseem ceeb rau kev taw qhia ntawm lub kaw lus.
· Lub Khoos Phis Tawj Module: Lub hauv paus ntawm INS, ua cov ntaub ntawv ntau yam los muab cov kev tshuaj xyuas qhov chaw tiag tiag.
INS txoj kev tiv thaiv rau kev cuam tshuam sab nraud ua rau nws tseem ceeb heev hauv kev tiv thaiv teb chaws. Txawm li cas los xij, nws sib ntaus nrog 'drift' - qhov kev poob qis ntawm qhov tseeb, uas yuav tsum tau muaj cov kev daws teeb meem zoo li sensor fusion rau kev txo qhov yuam kev (Chatfield, 1997).
Tshooj 2. Kev Ua Haujlwm Dynamics ntawm Fiber Optic Gyroscope:
Cov Fiber Optic Gyroscopes (FOGs) qhia txog lub caij nyoog hloov pauv hauv kev ntsuas kev sib hloov, siv lub teeb cuam tshuam. Nrog rau qhov tseeb ntawm nws lub hauv paus, FOGs yog qhov tseem ceeb rau kev ruaj khov thiab kev tsav tsheb hauv aerospace.
Cov FOGs ua haujlwm ntawm Sagnac effect, qhov twg lub teeb, hla mus rau hauv cov lus qhia rov qab hauv lub kauj fiber tig, qhia txog kev hloov pauv theem sib raug zoo nrog kev hloov pauv ntawm kev tig. Lub tshuab nuanced no txhais tau tias yog cov ntsuas qhov ceev ntawm lub kaum sab xis.
Cov khoom tseem ceeb muaj xws li:
· Qhov Chaw Teeb: Lub hauv paus pib, feem ntau yog laser, pib txoj kev taug kev sib koom ua ke.
· Cov kauj fiberIb txoj hlua khi kho qhov muag, ua rau lub teeb txoj kev mus ntev dua, yog li ua rau Sagnac effect loj dua.
· Photodetector: Cov khoom no pom cov qauv cuam tshuam ntawm lub teeb.
Tshooj 3: Qhov Tseem Ceeb ntawm Polarization Tswj Xyuas Fiber Loops:
Kev Tswj Xyuas Polarization (PM) Fiber Loops, quintessential rau FOGs, ua kom muaj lub xeev polarization sib xws ntawm lub teeb, qhov tseem ceeb txiav txim siab hauv kev cuam tshuam tus qauv. Cov fibers tshwj xeeb no, tawm tsam hom polarization dispersion, txhawb nqa FOG rhiab heev thiab cov ntaub ntawv tseeb (Kersey, 1996).
Kev xaiv cov PM fibers, uas raug txiav txim los ntawm kev ua haujlwm xav tau, cov yam ntxwv ntawm lub cev, thiab kev sib haum xeeb ntawm lub cev, cuam tshuam rau cov kev ntsuas kev ua tau zoo thoob plaws.
Ntu 4: Cov Ntawv Thov thiab Cov Pov Thawj Pom Tseeb:
FOGs thiab INS pom muaj kev cuam tshuam thoob plaws ntau yam kev siv, los ntawm kev tswj hwm kev tsav dav hlau tsis muaj neeg tsav mus rau kev ua kom muaj kev ruaj khov ntawm cov yeeb yaj kiab thaum muaj kev tsis paub tseeb txog ib puag ncig. Ib qho pov thawj rau lawv qhov kev ntseeg tau yog lawv qhov kev xa mus rau NASA's Mars Rovers, ua rau muaj kev nyab xeeb rau kev tsav nkoj sab nraud (Maimone, Cheng, thiab Matthies, 2007).
Cov kev lag luam kwv yees tias yuav muaj kev loj hlob ntawm cov thev naus laus zis no, nrog rau cov kev tshawb fawb tsom mus rau kev txhawb nqa lub zog ntawm lub kaw lus, cov matrices meej, thiab cov spectra adaptability (MarketsandMarkets, 2020).
