Munguva yematanho ekutanga etekinoroji, masisitimu ekufambisa akabuda sembiru dzekutanga, achifambisa kufambira mberi kwakawanda, kunyanya muzvikamu zvakakosha.Rwendo rwekubva kune yakareruka yekufamba kwemudenga kuenda kune yakaomesesa Inertial Navigation Systems (INS) inoburitsa pachena kuedza kusingachinji kwevanhu kwekuongorora uye kuona chokwadi.Ongororo iyi inoongorora zvakadzika mukati meINS yakaoma mechanics, ichiongorora yekucheka-kumucheto tekinoroji yeFiber Optic Gyroscopes (FOGs) uye basa rakakosha rePolarization mukuchengeta Fiber Loops.
Chikamu chekutanga: Kutsanangura Inertial Navigation Systems (INS):
Inertial Navigation Systems (INS) inomira pachena sezviyamuro zvekufambisa zvinozvimiririra, zvichinyatso computita nzvimbo yemotokari, mafambisirwo, uye kumhanya, zvisingaenderane nezvido zvekunze.Aya masisitimu anowiriranisa mafambiro uye anotenderera ma sensors, akabatana zvisina musono nemakomputa emhando yekutanga velocity, chinzvimbo, uye kutaridzika.
Iyo archetypal INS inosanganisira matatu emakadhinari zvikamu:
* Accelerometers: Izvi zvakakosha zvinhu zvinonyoresa mutsara wemotokari kukwirisa, kushandura mafambiro kuita data inoyerwa.
· Gyroscopes: Yakabatanidzwa pakuona angular velocity, izvi zvikamu zvakakosha kune system orientation.
· Computer Module: Iyo nerve centre yeINS, kugadzirisa multifaceted data kuburitsa chaiyo-nguva positional analytics.
Kusadzivirirwa kweINS kune kukanganisa kwekunze kunoita kuti ive yakakosha muzvikamu zvekudzivirira.Nekudaro, inonetsana ne 'drift' - kuderera zvishoma nezvishoma, zvichidikanwa mhinduro dzakaomarara senge sensor fusion yekuderedza kukanganisa (Chatfield, 1997).
Chikamu 2. Kushanda Dynamics yeFiber Optic Gyroscope:
Fiber Optic Gyroscopes (FOGs) inozivisa nguva yeshanduko mukutenderera kwekunzwa, inosimudzira kupindira kwechiedza.Nekurongeka pahwaro hwayo, maFOG akakosha kuti mota dzemuchadenga dzigadzikane uye kufamba.
FOGs inoshanda paSagnac mhedzisiro, uko mwenje, uchifamba munzira dzekaunda mukati meinotenderera fiber coil, unoratidza kushanduka kwechikamu kunoenderana nekutenderera kwekuchinja.Iyi nuanced mechanism inoshandura mune chaiyo angular velocity metrics.
Essential components zvinosanganisira:
· Chiedza Chitubu: Nzvimbo yekutanga, kazhinji laser, inotanga rwendo rwechiedza.
· Fiber Coil: Iyo coiled optical conduit, inorebesa nzira yechiedza, nekudaro ichikudza iyo Sagnac mhedzisiro.
· Photodetector: Ichi chikamu chinoziva kupindirana kwakaoma kwemaitiro echiedza.
Chikamu 3: Kukosha kwePolarization Kuchengetedza Fiber Loops:
Polarization Kuchengetedza (PM) Fiber Loops, quintessential yeFOGs, inovimbisa yunifomu polarization mamiriro echiedza, chinhu chakakosha chinotemerwa mukukanganisa pateni chaiyo.Aya mafiber akasarudzika, kurwisa polarization mode dispersion, bolster FOG senitivity uye chokwadi chedata (Kersey, 1996).
Sarudzo yePM fibers, inorairwa neanoshanda exigency, hunhu hwemuviri, uye systemic kuwirirana, inopesvedzera yakanyanya kuita metrics.
Chikamu chechina: Zvishandiso uye Humbowo hweEmpirical:
FOGs uye INS vanowana resonance pane akasiyana maapplication, kubva pakuronga zvisina kurongwa zvemuchadenga forays kusvika pakuona kugadzikana kwecinematic pakati pekusafungira kwezvakatipoteredza.Chiratidzo chekuvimbika kwavo kuiswa kwavo muNASA's Mars Rovers, kufambisa kutadza-kuchengetedzeka kwekufamba kwekunze (Maimone, Cheng, naMatthies, 2007).
Matekinoroji emusika anofanotaura niche iri kuwedzera yetekinoroji iyi, ine mavheji ekutsvagisa akanangana nekusimbisa sisitimu kusimba, chaiyo matrices, uye kuchinjika spectra (MarketsandMarkets, 2020).
