Lembetsani ku Social Media Yathu Kuti Mutumize Posachedwa
Munthawi yaukadaulo wotsogola kwambiri, makina apanyanja adakhala ngati mizati yoyambira, zomwe zidapangitsa kupita patsogolo kwambiri, makamaka m'magawo ofunikira kwambiri. Ulendo wochokera kumayendedwe osavuta akumwamba kupita kuukadaulo wapamwamba wa Inertial Navigation Systems (INS) ukuwonetsa zoyesayesa za anthu zofufuza ndikuzindikira zolondola. Kusanthula uku kumayang'ana mozama pamakina odabwitsa a INS, ndikuwunika ukadaulo wotsogola wa Fiber Optic Gyroscopes (FOGs) komanso gawo lofunikira la Polarization mu Kusunga Fiber Loops.
Gawo 1: Kuzindikira Mayendetsedwe Osasinthika a Inertial (INS):
Inertial Navigation Systems (INS) imadziwikiratu ngati zida zodziyimira pawokha, zomwe zimawerengera bwino momwe galimoto ilili, momwe ikulowera, komanso liwiro lake, osatengera zomwe zili kunja. Makinawa amalumikizana ndi masensa oyenda ndi ozungulira, kuphatikiza mosasunthika ndi mitundu yowerengera ya liwiro loyambira, malo, ndi mawonekedwe.
Archetypal INS imaphatikizapo zigawo zitatu zazikulu:
Ma Accelerometers: Zinthu zofunika izi zimalembetsa kuthamanga kwa mzere wagalimoto, kumasulira kusuntha kukhala deta yoyezeka.
· Ma Gyroscopes: Zophatikizira kudziwa kuthamanga kwa angular, zigawozi ndizofunikira kwambiri pakuwongolera dongosolo.
· Computer Module: Pakatikati pa mitsempha ya INS, kukonza deta yamitundumitundu kuti ipereke ma analytics a nthawi yeniyeni.
Kutetezedwa kwa INS ku zosokoneza zakunja kumapangitsa kuti ikhale yofunika kwambiri m'magawo achitetezo. Komabe, imalimbana ndi 'kugwedezeka' - kuwola pang'onopang'ono, kumafunikira mayankho apamwamba monga kuphatikizika kwa sensor kuti muchepetse zolakwika (Chatfield, 1997).
Gawo 2. Mphamvu Zogwirira Ntchito za Fiber Optic Gyroscope:
Ma Fiber Optic Gyroscopes (FOGs) amalengeza nyengo yosinthika pakuzindikira kozungulira, kusokoneza kusokoneza kwa kuwala. Ndi kulondola kwenikweni, ma FOG ndi ofunikira kuti magalimoto apamlengalenga azikhazikika komanso kuyenda.
Ma FOG amagwira ntchito pamphamvu ya Sagnac, pomwe kuwala, kumayenda mozungulira mkati mwa koyilo ya ulusi wozungulira, kumawonetsa kusintha kwa gawo komwe kumayenderana ndi kusintha kwa kasinthasintha. Makina ophatikizika awa amamasulira kumayendedwe olondola aang'ono.
Zofunikira zili ndi:
· Gwero Lowala: Poyambira, nthawi zambiri ndi laser, yomwe imayambitsa ulendo wolumikizana.
· Fiber Coil: Njira yopindika ya kuwala, imatalikitsa njira ya kuwala, motero imakulitsa mphamvu ya Sagnac.
· Photodetector: Chigawo ichi chimazindikira kusokoneza kwa kuwala.
Gawo 3: Kufunika kwa Polarization Kusunga Zingwe za Fiber:
Polarization Maintaining (PM) Fiber Loops, quintessential for FOGs, imatsimikizira kuwala kofananako, chomwe chimapangitsa kuti pakhale kusokoneza. Ulusi wapaderawu, wolimbana ndi kufalikira kwa ma polarization, kukhudzika kwa FOG komanso kutsimikizika kwa data (Kersey, 1996).
Kusankhidwa kwa ma fiber a PM, motsogozedwa ndi zovuta zogwirira ntchito, mawonekedwe a thupi, ndi mgwirizano wadongosolo, zimakhudza magwiridwe antchito apamwamba.
Gawo 4: Ntchito ndi Umboni Wamphamvu:
Ma FOG ndi INS amapeza kumveka pamitundu yosiyanasiyana, kuyambira pakupanga maulendo apamlengalenga osayendetsedwa ndi anthu mpaka kuwonetsetsa bata la kanema mkati mwa kusadziŵika kwa chilengedwe. Umboni wa kudalirika kwawo ndi kutumizidwa kwawo ku Mars Rovers ya NASA, kuthandizira kuyenda motetezeka kunja kwa dziko lapansi (Maimone, Cheng, and Matthies, 2007).
Mayendedwe amsika amaneneratu za kukwera kwamatekinoloje awa, okhala ndi ma vector ofufuza omwe cholinga chake ndi kulimbikitsa kulimba kwa dongosolo, masamu olondola, komanso mawonekedwe osinthika (MarketsandMarkets, 2020).

Chodzikanira:
- Apa tikulengeza kuti zithunzi zina zowonetsedwa patsamba lathu zimatengedwa kuchokera pa intaneti ndi Wikipedia ndicholinga chopititsa patsogolo maphunziro ndi kugawana zambiri. Timalemekeza ufulu wazinthu zaluntha wa onse omwe adalenga. Zithunzizi zimagwiritsidwa ntchito popanda cholinga chofuna kupindula ndi malonda.
