Lembetsani ku Social Media Yathu Kuti Mupeze Nkhani Yachangu
Mu nthawi ya kupita patsogolo kwaukadaulo, njira zoyendera zinayamba kukhala maziko, zomwe zinayambitsa kupita patsogolo kwakukulu, makamaka m'magawo ofunikira kwambiri. Ulendo wochokera ku njira zoyambira zoyendera zakuthambo kupita ku Inertial Navigation Systems (INS) zamakono ukuwonetsa khama la anthu losagonja lofufuza ndi kulondola kolondola. Kusanthula kumeneku kumayang'ana kwambiri makina ovuta a INS, kufufuza ukadaulo wamakono wa Fiber Optic Gyroscopes (FOGs) ndi gawo lofunika kwambiri la Polarization pakusunga Fiber Loops.
Gawo 1: Kuzindikira Njira Zoyendetsera Zinthu Zosafunikira (INS):
Inertial Navigation Systems (INS) imadziwika ngati njira yodziyimira yokha yoyendetsera galimoto, kuwerengera bwino malo, momwe galimoto ilili, ndi liwiro lake, popanda zizindikiro zakunja. Machitidwewa amagwirizanitsa masensa oyenda ndi ozungulira, ogwirizana bwino ndi zitsanzo zamakompyuta kuti azitha kuyendetsa bwino liwiro, malo, ndi momwe galimoto ilili.
INS ya archetypal imaphatikizapo zigawo zitatu zazikulu:
· Ma Accelerometer: Zinthu zofunika kwambirizi zimalembetsa kuthamanga kwa galimoto, zomwe zimapangitsa kuti mayendedwe ake akhale deta yoyezeka.
· Ma Gyroscope: Ofunika kwambiri pozindikira liwiro la angular, zigawo izi ndizofunikira kwambiri pakuwongolera dongosolo.
· Module ya Pakompyuta: Pakati pa mitsempha ya INS, pokonza deta yochuluka kuti ipereke kusanthula kwa nthawi yeniyeni.
Chitetezo cha INS ku zosokoneza zakunja chimachipangitsa kukhala chofunikira kwambiri m'magawo achitetezo. Komabe, chimalimbana ndi 'kusuntha' - kuwonongeka pang'onopang'ono kwa kulondola, zomwe zimafuna njira zamakono monga kuphatikiza kwa sensor kuti zichepetse zolakwika (Chatfield, 1997).
Gawo 2. Mphamvu Yogwirira Ntchito ya Fiber Optic Gyroscope:
Ma Fiber Optic Gyroscopes (FOGs) akuwonetsa nthawi yosintha momwe kuwala kumayendera, zomwe zimagwiritsa ntchito kusokoneza kwa kuwala. Popeza kuwalako kuli kolondola kwambiri, ma FOG ndi ofunikira kwambiri kuti magalimoto oyendetsa ndege azikhala olimba komanso oyenda bwino.
Ma FOG amagwira ntchito pa Sagnac effect, pomwe kuwala, komwe kumadutsa mbali zina mkati mwa coil yozungulira ya ulusi, kumawonetsa kusintha kwa gawo komwe kumagwirizana ndi kusintha kwa liwiro lozungulira. Njira yosinthika iyi imasintha kukhala miyeso yeniyeni ya angular velocity.
Zigawo zofunika kwambiri ndi izi:
· Gwero la Kuwala: Malo oyambira, nthawi zambiri ndi laser, yomwe imayambitsa ulendo wogwirizana wa kuwala.
· Chophimba cha Ulusi: Msewu wozungulira wowala, umatalikitsa njira ya kuwala, motero umakulitsa mphamvu ya Sagnac.
· Chowunikira zithunzi: Gawoli limazindikira mawonekedwe ovuta a kuwala.
Gawo 3: Kufunika kwa Polarization Kusunga Ma Fiber Loops:
Ma Fiber Loops Osungira Polarization (PM), omwe ndi ofunika kwambiri kwa ma FOG, amatsimikizira kuti kuwala kumakhala kofanana, zomwe zimapangitsa kuti pakhale kulondola kwa mawonekedwe olowererapo. Ulusi wapaderawu, womwe umalimbana ndi kufalikira kwa njira ya polarization, umathandizira kukhudzidwa kwa FOG komanso kutsimikizika kwa deta (Kersey, 1996).
Kusankhidwa kwa ulusi wa PM, komwe kumayendetsedwa ndi zofunikira pakugwira ntchito, mawonekedwe a thupi, ndi mgwirizano wa dongosolo, kumakhudza miyezo yonse ya magwiridwe antchito.
Gawo 4: Kugwiritsa Ntchito ndi Umboni Wovomerezeka:
FOGs ndi INS zimapeza mphamvu pa ntchito zosiyanasiyana, kuyambira kukonza maulendo a mlengalenga opanda anthu mpaka kuonetsetsa kuti zinthu zili bwino pakati pa kusatsimikizika kwa chilengedwe. Umboni wa kudalirika kwawo ndi kutumizidwa kwawo mu Mars Rovers a NASA, zomwe zimathandiza kuti kuyenda kwa zinthu zakuthambo kukhale kotetezeka (Maimone, Cheng, ndi Matthies, 2007).
Njira zogulitsira msika zikulosera kukula kwa ukadaulo uwu, ndi ma vector ofufuza omwe cholinga chake ndi kulimbikitsa kulimba kwa dongosolo, ma matrices olondola, ndi ma spectra osinthika (MarketsandMarkets, 2020).

Chodzikanira:
- Apa tikulengeza kuti zithunzi zina zomwe zimawonetsedwa patsamba lathu zimasonkhanitsidwa kuchokera pa intaneti ndi Wikipedia kuti zipititse patsogolo maphunziro ndi kugawana zambiri. Timalemekeza ufulu waukadaulo wa opanga onse oyamba. Zithunzi izi sizigwiritsidwa ntchito popanda cholinga chofuna kupeza phindu lamalonda.
- Ngati mukukhulupirira kuti zomwe zagwiritsidwa ntchito zikuphwanya ufulu wanu wa kukopera, chonde titumizireni uthenga. Tili okonzeka kuchitapo kanthu moyenera, kuphatikizapo kuchotsa zithunzi kapena kupereka umboni woyenera, kuti titsimikizire kuti malamulo ndi malamulo okhudza katundu wanzeru akutsatira. Cholinga chathu ndikusunga nsanja yokhala ndi nkhani zambiri, yolungama, komanso yolemekeza ufulu wa katundu wa ena.
- Chonde titumizireni uthenga kudzera mu njira iyi yolumikizirana,email: sales@lumispot.cn. Tikudzipereka kuchitapo kanthu mwachangu tikalandira chidziwitso chilichonse ndikuwonetsetsa kuti tikugwirizana 100% pothetsa mavuto aliwonse otere.
