Inertial sensors muaj xws li accelerometers (tseem hu ua acceleration sensors) thiab angular velocity sensors (tseem hu ua gyroscopes), nrog rau lawv ib leeg-, dual-, thiab triple-axis ua ke inertial ntsuas units (tseem hu ua IMUs) thiab AHRS.
Lub accelerometer yog tsim los ntawm kev tshawb nrhiav huab hwm coj (tseem hu ua qhov loj me), kev txhawb nqa, potentiometer, lub caij nplooj ntoos hlav, lub damper thiab lub plhaub.Qhov tseeb, nws siv lub hauv paus ntsiab lus ntawm acceleration los xam lub xeev ntawm ib qho khoom txav hauv qhov chaw.Thaum xub thawj, lub accelerometer tsuas paub qhov acceleration nyob rau hauv ntsug kev taw qhia ntawm nto.Nyob rau hauv thaum ntxov hnub, nws tsuas yog siv nyob rau hauv lub ntsuas system rau ntes aircraft overload.Tom qab kev txhim kho kev ua haujlwm thiab kev ua kom zoo dua qub, tam sim no muaj peev xwm nkag siab qhov nrawm ntawm cov khoom hauv txhua qhov kev taw qhia.Lub ntsiab tam sim no yog 3-axis accelerometer, uas ntsuas cov ntaub ntawv nrawm ntawm cov khoom ntawm peb axes ntawm X, Y, thiab Z hauv qhov chaw sib koom ua ke, uas tuaj yeem cuam tshuam tag nrho cov khoom txav ntawm cov khoom txhais lus.
Qhov ntxov tshaj plaws gyroscopes yog txhua yam gyroscopes nrog built-in high-speed rotating gyroscopes.Vim tias lub gyroscope tuaj yeem tswj tau qhov kev sib hloov ceev thiab ruaj khov ntawm lub gimbal bracket, qhov ntxov tshaj plaws gyroscopes yog siv nyob rau hauv navigation los txheeb xyuas cov kev taw qhia, txiav txim siab tus cwj pwm thiab xam lub angular tshaj tawm.Tom qab ntawd, maj mam siv hauv cov cuab yeej dav hlau.Txawm li cas los xij, hom kev siv tshuab muaj cov kev xav tau siab ntawm kev ua haujlwm raug thiab yooj yim cuam tshuam los ntawm kev co sab nraud, yog li kev xam qhov tseeb ntawm cov tshuab gyroscope tsis tau siab.
Tom qab ntawd, txhawm rau txhim kho qhov tseeb thiab siv tau, lub hauv paus ntsiab lus ntawm gyroscope tsis yog siv tshuab xwb, tab sis tam sim no laser gyroscope (lub hauv paus ntsiab lus ntawm kev sib txawv ntawm qhov muag), fiber ntau optic gyroscope (Sagnac effect, optical path txawv hauv paus ntsiab lus) tau tsim.a) thiab microelectromechanical gyroscope (xws li MEMS, uas yog raws li Coriolis quab yuam txoj cai thiab siv nws cov kev hloov pauv sab hauv los xam cov angular tshaj tawm, MEMS gyroscopes yog qhov ntau tshaj plaws hauv smartphones).Vim yog kev siv MEMS thev naus laus zis, tus nqi ntawm IMU kuj tau poob ntau heev.Tam sim no, nws tau siv dav, thiab ntau tus neeg siv nws, xws li xov tooj ntawm tes thiab tsheb mus rau dav hlau, cuaj luaj, thiab dav hlau.Nws kuj yog cov saum toj no-hais sib txawv precisions, txawv daim ntawv thov teb, thiab txawv cov nqi.
Thaum Lub Kaum Hli Ntuj xyoo tas los, inertial sensor loj Safran tau txais qhov tsis ntev los no-rau-sau npe Norwegian chaw tsim khoom ntawm gyroscope sensors thiab MEMS inertial systems Sensonor los nthuav nws txoj kev lag luam rau hauv MEMS-based sensor technology thiab lwm yam kev siv,
Goodwill Precision Machinery muaj cov cuab yeej paub tab thiab kev paub dhau los hauv thaj chaw ntawm MEMS module tsev tsim khoom, nrog rau cov neeg siv khoom ruaj khov thiab koom tes.
Ob lub tuam txhab Fab Kis, ECA Group thiab iXblue, tau nkag mus rau theem ua ntej kev sib koom ua ke ntawm kev sib tham tshwj xeeb.Kev sib koom ua ke, txhawb nqa los ntawm ECA Group, yuav tsim cov European high-tech thawj coj hauv kev ua dej hiav txwv, inertial navigation, chaw thiab photonics.ECA thiab iXblue yog cov koom tes ntev.Partner, ECA integrates iXblue's inertial thiab underwater positioning systems rau hauv nws autonomous underwater tsheb rau naval mine tsov rog.
Inertial Technology thiab Inertial Sensor Development
Los ntawm 2015 txog 2020, qhov sib xyaw ua ke txhua xyoo kev loj hlob ntawm lub ntiaj teb inertial sensor kev lag luam yog 13.0%, thiab kev lag luam loj hauv 2021 yog kwv yees li 7.26 billion US dollars.Thaum pib ntawm txoj kev loj hlob ntawm inertial technology, nws yog tsuas yog siv nyob rau hauv lub teb ntawm kev tiv thaiv thiab tub rog kev lag luam.High precision thiab siab rhiab heev yog cov yam ntxwv tseem ceeb ntawm inertial technology khoom rau kev lag luam tub rog.Cov kev cai tseem ceeb tshaj plaws rau Is Taws Nem ntawm Tsheb, kev tsav tsheb tsis muaj zog, thiab kev txawj ntse hauv tsheb yog kev nyab xeeb thiab kev ntseeg siab, thiab tom qab ntawd kev nplij siab.Tom qab tag nrho cov no yog cov sensors, tshwj xeeb tshaj yog siv MEMS inertial sensors, tseem hu ua inertial sensors.ntsuas ntsuas.
Inertial sensors (IMU) feem ntau yog siv los ntsuas thiab ntsuas acceleration thiab rotational motion sensors.Lub hauv paus ntsiab lus no yog siv nyob rau hauv MEMS sensors nrog ib txoj kab uas hla ntawm ze li ntawm ib nrab ib 'meter' rau fiber optic li nrog ib txoj kab uas hla ntawm ze li ntawm ib nrab ib 'meter'.Inertial sensors tuaj yeem siv dav hauv cov neeg siv khoom siv hluav taws xob, cov khoom ua si ntse, tsheb hluav taws xob, kev lag luam automation, ntse kev ua liaj ua teb, khoom siv kho mob, instrumentation, Robots, kev tsim kho tshuab, navigation systems, satellite kev sib txuas lus, tub rog riam phom thiab ntau lwm yam.
Tam sim no ntshiab high-end inertial sensor ntu
Inertial sensors yog qhov tseem ceeb hauv navigation thiab davhlau tswj systems, txhua hom kev lag luam dav hlau, thiab satellite trajectory kho thiab stabilization.
Kev nce ntawm cov hnub qub ntawm micro thiab nanosatellite rau lub ntiaj teb internet broadband thiab kev saib xyuas lub ntiaj teb tej thaj chaw deb, xws li SpaceX thiab OneWeb, yog tsav qhov kev thov rau satellite inertial sensors mus rau theem tsis tau muaj dua.
Kev loj hlob thov rau inertial sensors nyob rau hauv kev lag luam foob pob hluav taws launcher subsystems ntxiv boosts lub lag luam xav tau.
Robotics, logistics thiab automation systems tag nrho xav tau inertial sensors.
Tsis tas li ntawd, raws li txoj cai tsheb sib txuas mus ntxiv, cov saw hlau logistics muaj kev hloov pauv.
Kev nce siab hauv kev xav tau hauv qab no txhawb nqa kev siv kev lag luam hauv tsev
Tam sim no, thev naus laus zis hauv domestic VR, UAV, tsis muaj neeg siv, neeg hlau thiab lwm yam kev siv thev naus laus zis tau dhau los ua neeg paub tab, thiab daim ntawv thov tau maj mam nrov, uas ua rau cov neeg siv khoom hauv tsev MEMS inertial sensor xav tau nce ib hnub.
Tsis tas li ntawd, nyob rau hauv kev lag luam kev lag luam ntawm kev tshawb nrhiav roj av, kev soj ntsuam thiab daim ntawv qhia, kev tsheb ciav hlau ceev, kev sib txuas lus hauv kev txav, kav hlau txais xov tus cwj pwm saib xyuas, photovoltaic mus txog qhovtwg, kev saib xyuas kev noj qab haus huv, kev soj ntsuam kev co thiab lwm yam kev lag luam, cov qauv ntawm daim ntawv thov ntse yog pom tseeb. , uas tau dhau los ua lwm yam rau kev loj hlob tsis tu ncua ntawm domestic MEMS inertial sensor lag luam.Ib tug pusher.
Raws li cov cuab yeej ntsuas tseem ceeb hauv aviation thiab aerospace teb, inertial sensors yeej ib txwm yog ib qho ntawm cov cuab yeej tseem ceeb koom nrog hauv kev tiv thaiv kev ruaj ntseg hauv tebchaws.Feem ntau ntawm domestic inertial sensor ntau lawm ib txwm yog lub xeev cov koom haum ncaj qha ntsig txog kev tiv thaiv lub teb chaws, xws li AVIC, aerospace, ordnance, thiab Tuam Tshoj Shipbuilding.
Niaj hnub no, lub domestic inertial sensor kev lag luam xav tau tseem kub, txawv teb chaws kev teeb meem yog maj mam overcome, thiab domestic zoo heev inertial sensor tuam txhab uas muag tau sawv ntawm kev sib tshuam ntawm ib tug tshiab era.
Raws li kev tsav tsheb tsav tsheb tau pib maj mam hloov pauv los ntawm theem kev loj hlob mus rau qhov nruab nrab thiab siab ntim ntau lawm, nws yog qhov pom tau tias yuav muaj kev kub ntxhov hauv lub tshav pob kom txo tau lub zog noj, qhov loj me, qhov hnyav, thiab tus nqi thaum tuav lossis nthuav kev ua haujlwm.
Hauv particular, kev paub txog kev tsim khoom loj ntawm micro-electromechanical inertial li tau ua cov khoom siv thev naus laus zis siv dav hauv pej xeem thaj chaw uas qis dua tuaj yeem ua tau raws li daim ntawv thov.Tam sim no, daim ntawv thov teb thiab nplai tau qhia txog kev loj hlob sai.
