Lub hauv paus ntsiab lus thiab kev faib tawm ntawm cov huab
(1) txoj ntsiab cai
Lub hauv paus ntsiab lus ntawm huab yog hu ua Sagnac cov nyhuv hauv physics. Nyob rau hauv lub teeb lub teeb Yog tias lub teeb lub teeb tsa tau sib hloov ntawm qhov chaw inertial, uas yog ib qho kev sib txawv ntawm txoj kev sib hloov ntawm txoj kev sib hloov ntawm lub kaum sab xis. Kev sib hloov lub nrawm yog xam los ntawm kev siv cov theem sib txawv ntsuas los ntawm photoelectric ntsuas.
Los ntawm cov qauv, qhov ntev dua cov fiber ntau, qhov loj dua qhov kho qhov muag hluav taws xob, tus luv luv lub wavelength. Cov txiaj ntsig zoo tshaj plaws ntawm kev cuam tshuam cov txiaj ntsig yog. Yog li qhov tseem ceeb dua qhov ntim ntawm huab, qhov siab dua qhov tseeb. Sagnac nyhuv yog qhov tseem ceeb ib qho kev cuam tshuam cov nyhuv, uas yog ib qho tseem ceeb heev rau kev tsim cov dej noo.
Lub hauv paus ntsiab lus ntawm cov huab yog tias lub nqaj ntawm lub teeb xa tawm los ntawm cov raj yees duab photoelectric thiab dhau los ntawm cov coupler (ib qho kawg nkag mus rau hauv peb nres). Ob lub nqaj nkag rau hauv lub nplhaib hauv cov lus qhia sib txawv los ntawm lub nplhaib thiab tom qab ntawd rov qab ib ncig ntawm ib lub voj voog rau kev sib koom tes sib haum. Lub teeb xa rov qab mus rau LED thiab kuaj pom cov kev siv los ntawm LED. Lub hauv paus ntsiab lus ntawm cov huab zoo li yooj yim, tab sis qhov tseem ceeb tshaj plaws yog yuav ua li cas tshem tawm cov kev kho kho kab ntawm ob qho teeb meem tseem ceeb-muaj teeb meem tseem ceeb uas yuav pos huab.
Txoj cai ntawm fiber ntau optic gyroscope
(2) kev faib tawm
Raws li tus ua haujlwm ua haujlwm, fiber ntau optic gyroscopes tuaj yeem faib ua ke optic gyrosouin optic gyroscope fiber ntau optic gyroscope (b-pos). Tam sim no, tshaj plaws cov fiber ntau optic gyroscope yog qhov sib cuam tshuam fiber ntau optic gyroscope optic fiber optic gyroscope), uas yog siv dav. Nws siv ntau-tig fiber ntau chev los txhim kho cov sagnac nyhuv. Ntawm qhov tod tes, ob chav nqaj hlau ci ntsa iab sib xyaw ntawm cov neeg muaj ntau hom-hom fiber ntau-hom muaj zog, uas yuav ua rau tag nrho cov qauv ntau dua complex.
Raws li hom Voj, Huab tuaj yeem muab faib ua qhib-voj voos post thiab kaw-voj huab. Qhib-Voj Fiber Optic Gyroscope (OGG) muaj qhov zoo ntawm cov qauv yooj yim, tus nqi qis, muaj kev ntseeg siab, thiab tsis tshua muaj hluav taws xob. Ntawm qhov tod tes, qhov tsis zoo ntawm Ogg yog cov tswv yim tsis zoo-tawm tawm ntawm kab thiab cov khoom me me. Yog li ntawd, nws yog tsuas yog siv los ua lub kaum sensor. Cov qauv theem pib ntawm qhib-voj yog tias lub nplhaib ob-nqaj cuam tshuam. Thiaj li, nws yog siv feem ntau hauv qhov xwm txheej ntawm qhov qis qis thiab ntim me me.
Kev Kawm Ua Ntej ntawm Huab
Huab yog tsuas yog siv los ntsuas angular ntev, thiab ib qho kev ntsuas yog qhov ua yuam kev.
(1) suab nrov
Lub suab nrov ntawm cov huab yog feem ntau ua rau lub qhov muag lossis photicelectric lossis kev txiav txim siab tsawg kawg ntawm cov dej noo. Nyob rau hauv fiber ntau gyroscope (huab), tus parameter cim cov zis dawb ntawm lub suab nrov dawb ntawm cov coefficient ntawm cov bandwidth. Xws li cov suab nrov dawb xwb, cov ntsiab lus ntawm kev taug kev ntawm kev taug kev ntawm kev ntsuas kev ntsuas kom tau yooj yim rau cov hauv paus square rau hauv cov bandwidth tshwj xeeb
Yog tias muaj lwm hom suab nrov lossis drift, peb ib txwm siv allan kev txheeb xyuas ntawm kev sib txawv kom tau txais kev taug kev random los ntawm txoj kev tsim nyog.
(2) xoom drift
Lub kaum sab xis suav yog xav tau thaum siv pos. Lub kaum sab xis yog tau los ntawm angular velocity kev koom ua ke. Hmoov tsis zoo, lub drift yog sau tom qab lub sijhawm ntev, thiab qhov yuam kev tau loj dua thiab loj dua. Feem ntau hais lus, rau cov lus thov ceev (luv luv), suab nrov cuam tshuam lub system. Tseem, rau cov ntawv thov navigation (sijhawm ntev), xoom drift muaj cov cawv tseem ceeb ntawm lub system.
(3) qhov sib teev (teev tshwj xeeb)
Qhov ntsuas me me qhov yuam kev yog, qhov ntau dua qhov tshwm sim yog.
Beijing Rofoeltronics Co., Ltd. Sib Koom Tes Ua Si " Peb lub tuam txhab feem ntau yog koom nrog kev tshawb fawb ywj pheej thiab tsim qauv, thiab muab cov kev pabcuam tsim kho tshiab, thiab cov kws tshawb fawb txog kev lag luam thiab cov kws tshawb nrhiav kev lag luam. Tom qab xyoo ntawm kev ywj pheej tshiab, nws tau tsim cov khoom nplua nuj thiab zoo nkauj, hluav taws xob siv hauv nroog, hluav taws xob, kev kawm, kev kho mob thiab lwm yam kev lag luam.
Peb tab tom nrhiav rau pem hauv ntej rau kev koom tes nrog koj!
