Nyorera kuSocial Media Yedu Kuti Uwane Chiziviso Chinokurumidza
Munguva yekufambira mberi kukuru kwetekinoroji, masisitimu ekufambisa akabuda senzvimbo huru, achitungamira kufambira mberi kwakawanda, kunyanya muzvikamu zvakakosha. Rwendo kubva pakufamba kwepasi kwedenga kusvika kuInertial Navigation Systems (INS) yakapfava inoratidza kuedza kwevanhu kutsvaga nekuongorora kururama. Ongororo iyi inotarisa zvakadzama mumakanika akaomarara eINS, ichiongorora tekinoroji yemazuva ano yeFiber Optic Gyroscopes (FOGs) uye basa guru rePolarization mukuchengetedza Fiber Loops.
Chikamu 1: Kunzwisisa Inertial Navigation Systems (INS):
Inertial Navigation Systems (INS) dzinoshanda senzira dzekufambisa dzinozvishandira dzoga, dzichiverenga nzvimbo yemotokari, kurongeka kwayo, uye kumhanya kwayo, dzisingabatanidzwi nezviratidzo zvekunze. Masisitimu aya anobatanidza masensa ekufamba uye kutenderera, zvichibatanidzwa nemamodheru ekuverenga kuti mota iite kumhanya kwayo kwekutanga, nzvimbo yayo, uye kurongeka kwayo.
INS ye archetypal inosanganisira zvikamu zvitatu zvikuru:
· Accelerometers: Zvinhu izvi zvakakosha zvinonyoresa kumhanya kwemotokari nenzira yakatsetseka, zvichishandura kufamba kwayo kuita data rinoyerwa.
· MaGyroscope: Akakosha pakuona kumhanya kwekona, zvikamu izvi zvakakosha pakutungamira kwehurongwa.
· Computer Module: Nzvimbo yepakati yetsinga yeINS, inogadzirisa data rine mativi akawanda kuti ibudise ongororo yemamiriro ezvinhu panguva chaiyo.
Kusadzivirirwa kweINS kumatambudziko ekunze kunoita kuti ive yakakosha muzvikamu zvekudzivirira. Zvisinei, inosangana ne'drift' - kuora kwekururama zvishoma nezvishoma, zvichiita kuti pave nemhinduro dzakaoma senge sensor fusion yekuderedza kukanganisa (Chatfield, 1997).
Chikamu 2. Maitiro Ekushanda kweFiber Optic Gyroscope:
MaFiber Optic Gyroscopes (FOGs) anoratidza nguva yekuchinja mukunzwa kwekutenderera, zvichishandisa kupindira kwechiedza. Nekunyatsorongeka kwayo, maFOG akakosha pakugadzirisa uye kufamba kwemotokari dzemuchadenga.
MaFOG anoshanda paSagnac effect, apo chiedza, chichifamba munzira dzakasiyana mukati me fiber coil inotenderera, chinoratidza phase shift inoenderana nekuchinja kwe rotational rate. Iyi nuanced mechanism inoshandura kuita angular velocity metrics chaiyo.
Zvikamu zvakakosha zvinosanganisira:
· Chitubu cheChiedza: Nzvimbo yekutanga, inowanzo shandiswa nelaser, inotanga rwendo rwechiedza rwakabatana.
· Fiber Coil: Mugero wechiedza wakakomberedzwa, unorebesa nzira yechiedza, nokudaro uchiwedzera simba reSagnac.
· Photodetector: Chikamu ichi chinoona maitiro akaomarara echiedza.
Chikamu 3: Kukosha kwePolarization Kuchengetedza Fiber Loops:
MaFiber Loops ekuchengetedza polarization (PM), ayo anonyanya kukosha kuFOGs, anovimbisa mamiriro akafanana epolarization yechiedza, chinhu chakakosha pakusarudza kwakarurama kwemaitiro ekupindirana. Aya mafibers akasarudzika, anodzivirira kupararira kwepolarization mode, anotsigira FOG sensitivity uye kuvimbika kwedata (Kersey, 1996).
Kusarudzwa kwemafiber ePM, kunoenderana nezvinodiwa pakushanda, hunhu hwemuviri, uye kurongeka kwehurongwa, zvinopesvedzera zviyero zvekushanda zvakazara.
Chikamu 4: Mashandisirwo uye Humbowo Hwechokwadi:
FOGs neINS zvinowana rutsigiro mukushandiswa kwakasiyana-siyana, kubva pakuronga mafambiro emuchadenga asina munhu kusvika pakuona kugadzikana kwemufirimu pakati pekusaziva kwezvakatipoteredza. Chiratidzo chekuvimbika kwavo ndechekuiswa kwavo muMars Rovers yeNASA, zvichiita kuti kufamba kunze kwenyika kusashande zvakanaka (Maimone, Cheng, naMatthies, 2007).
Nzira dzemusika dzinofanotaura kukura kuri kuita matekinoroji aya, nematanho ekutsvagisa akagadzirirwa kusimbisa kusimba kwehurongwa, matrix akarurama, uye maspectra anochinjika (MarketsandMarkets, 2020).

Kuzviramba:
- Tinozivisa kuti mimwe mifananidzo inoratidzwa pawebhusaiti yedu inotorwa kubva painternet neWikipedia nechinangwa chekufambisira mberi dzidzo nekugovana ruzivo. Tinoremekedza kodzero dzepfungwa dzevagadziri vepakutanga vese. Mifananidzo iyi inoshandiswa pasina chinangwa chekuwana purofiti.
- Kana muchifunga kuti chero zviri mukati zvinoshandiswa zvinotyora kodzero dzenyu dzekodzero, ndapota taurai nesu. Tinoda zvikuru kutora matanho akakodzera, kusanganisira kubvisa mifananidzo kana kupa humbowo hwakakodzera, kuti tive nechokwadi chekuti mitemo nemitemo yepfuma yepfungwa inotevedzwa. Chinangwa chedu ndechekuchengetedza puratifomu ine zviri mukati, yakarurama, uye inoremekedza kodzero dzepfuma yepfungwa dzevamwe.
