Umqondo oyisisekelo we-fiber optic gyroscope

1, Umqondo oyisisekelo we-fiber optic gyroscope

I-fiber optic gyroscope yesimanje iyithuluzi elikwazi ukunquma ngokunembile ukuma kwezinto ezihambayo, iyithuluzi lokuzulazula elingasebenzi elisetshenziswa kabanzi ekundizeni kwesimanjemanje, ukuzulazula, i-aerospace kanye nomkhakha wezokuvikela, ukuthuthukiswa kwayo kunokubaluleka kwamasu okubaluleke kakhulu embonini yezwe, ukuvikela izwe. kanye nokunye ukuthuthukiswa kobuchwepheshe obuphezulu.

2. Incazelo ye-fiber optic gyro

I-Fiber optic gyroscope iyisici esibucayi esisekelwe kumakhoyili e-fiber optical.Ukukhanya okuphuma ku-laser diode kusakazeka ezinhlangothini ezimbili eduze kwe-fiber optical.Umehluko womzila wokusabalalisa ukukhanya unquma ukugudluka kwe-angular kwento ebucayi.

Izinzuzo ze-fiber optic gyroscope uma kuqhathaniswa ne-gyroscope yemishini yendabuko zonke ziyisimo esiqinile, azikho izingxenye ezijikelezayo nezingxenye zokungqubuzana, impilo ende, ububanzi obukhulu obuguquguqukayo, isiqalo esisheshayo, isakhiwo esilula, usayizi omncane nesisindo esilula.Uma kuqhathaniswa ne-laser gyroscope, i-fiber optic gyroscope ayinayo inkinga yokunamathisela futhi ayidingi umshini oqondile womzila we-optical block ye-quartz, ngakho-ke izindleko ziphansi.

3, Isimiso sokusebenza esiyisisekelo se-Fiber optic gyro

Ukuqaliswa kwe-fiber optic gyroscope kusekelwe ikakhulukazi kumbono we-Segnick: lapho i-beam yokukhanya ihamba ngesiteshi esimise njengendandatho, uma isiteshi sendandatho sona sinesivinini sokujikeleza, isikhathi esidingekayo ukuze ukukhanya kuhambe ngendlela ukuzungezisa isiteshi kungaphezu kwesikhathi esidingekayo ukuze uhambe uye kwelinye icala lalesi siteshi.Lokhu kusho ukuthi uma iluphu yokubona izungeza, ububanzi bokukhanya be-loop ebonakalayo bushintsha ezindleleni ezihlukene zokuhamba ngokuphathelene nobubanzi bokukhanya beluphu ekuphumuleni.Kusetshenziswa lolu shintsho ebangeni le-optical, umehluko wesigaba phakathi kwezihibe ezimbili ze-optical noma ukuguqulwa komphetho wokuphazamiseka kutholwa, futhi isivinini se-angular sokujikeleza kwe-optical loop singalinganiswa, okuyisimiso sokusebenza se-fiber optic gyroscope.

4, Isingeniso sethiyori kaSegnick

Ithiyori ye-Seignik ithi lapho i-beam yokukhanya iqhubekela phambili ku-loop, uma iluphu ngokwayo inesivinini sokuzungeza, kusho ukuthi kuthatha isikhathi esithe xaxa ukuthi ukukhanya kuqhubekele ohlangothini lokuzungezisa iluphu kunokuba iqhubekele ngokuphambene. isiqondiso sokujikeleza kweluphu.

Lokhu kusho ukuthi uma iluphu yokubona izungeza, ububanzi bokukhanya be-loop yokubona bushintsha eziqondisweni ezihlukile eziya phambili ngokuhlobene nobubanzi bokukhanya beluphu ekuphumuleni.Ngokusebenzisa lolu shintsho kububanzi be-optical, uma ukuphazamiseka kukhiqizwa phakathi kokukhanya okuqhubekela phambili ngezindlela ezihlukene ukukala isivinini sokuzungezisa iluphu, kungadalwa i-interferometric fibre optic gyroscope.Uma usebenzisa lolu shintsho endleleni ye-optical ye-loop ukuze ufinyelele ukuphazamiseka phakathi kokukhanya okujikelezayo ku-loop, okungukuthi, ngokulungisa imvamisa ye-resonant yokukhanya ku-optical fiber loop bese ukala isivinini sokujikeleza kweluphu, i-resonant fibre optic gyroscope ingakhiqizwa.
