Ibisubizo bya FOG

Kugenda kwa Inertial ni iki?

Shingiro ryo Kutagira Inertial

Amahame shingiro yo kugendana inertial arasa nubundi buryo bwo kugenda. Ishingiye ku kubona amakuru yingenzi, harimo umwanya wambere, icyerekezo cyambere, icyerekezo nicyerekezo cyerekezo kuri buri mwanya, kandi buhoro buhoro uhuza aya makuru (bisa nibikorwa byo guhuza imibare) kugirango umenye neza ibipimo ngenderwaho, nk'icyerekezo n'umwanya.

Uruhare rwa Sensors muri Inertial Navigation

Kugirango ubone icyerekezo kigezweho (imyifatire) hamwe namakuru yamakuru yikintu cyimuka, sisitemu yo kugendana inertial ikoresha urutonde rwibikoresho bikomeye, bigizwe ahanini na moteri yihuta na giroskopi. Ibyo byuma byifashisha bipima umuvuduko wihuta no kwihuta kwabatwara muburyo butagaragara. Ibyatanzwe noneho bihuzwa kandi bigatunganywa mugihe kugirango bikure umuvuduko namakuru ajyanye namakuru. Ibikurikiraho, aya makuru yahinduwe muri sisitemu yo guhuza ibikorwa, hamwe namakuru yambere yumwanya wambere, bikarangirana no kugena aho ubwikorezi bugeze.

Amahame yimikorere ya sisitemu yo kugendagenda neza

Sisitemu yo kugendana inertial ikora nkuko yonyine, sisitemu yo gufunga-gufunga imbere. Ntabwo bashingira kumyanya-nyayo yamakuru yo hanze kugirango bakosore amakosa mugihe cyabatwara. Nkibyo, sisitemu imwe yo kugendana inertial ikwiranye nigihe gito cyo kugendana imirimo. Kubikorwa byigihe kirekire, bigomba guhuzwa nubundi buryo bwo kugenda, nka sisitemu yo kugendana na satelite, kugirango ikosore rimwe na rimwe amakosa yimbere.

Ihishurwa rya Inertial Navigation

Muri tekinoroji igezweho yo kugendana, harimo kugendagenda mu kirere, kugendesha icyogajuru, hamwe na radiyo, kugendana inertial biragaragara ko byigenga. Ntabwo isohora ibimenyetso mubidukikije cyangwa ntibiterwa nibintu byo mwijuru cyangwa ibimenyetso byo hanze. Kubwibyo, sisitemu yo kugendana inertial itanga urwego rwohejuru rwo guhisha, bigatuma biba byiza kubisabwa bisaba ibanga rikomeye.

Igisobanuro cyemewe cyo Kutagira Inertial Navigation

Sisitemu ya Inertial Navigation Sisitemu (INS) nuburyo bwo kugereranya ibipimo byo kugereranya ikoresha giroskopi na moteri yihuta nka sensor. Sisitemu, ishingiye ku bisohoka bya giroskopi, ishyiraho sisitemu yo guhuza ibikorwa mu gihe ikoresha ibisohoka byihuta kugira ngo ibare umuvuduko n'umwanya w'abatwara muri sisitemu yo guhuza ibikorwa.

Porogaramu ya Inertial Navigation

Ikoranabuhanga ridafite ubuvumbuzi ryabonye porogaramu nini mu bice bitandukanye, birimo ikirere, indege, inyanja, ubushakashatsi bwa peteroli, geodey, ubushakashatsi ku nyanja, gucukura geologiya, robotike, na sisitemu ya gari ya moshi. Hamwe no kwinjizamo ibyuma bitera imbere, tekinoroji yubukorikori yaguye akamaro kayo mu nganda z’imodoka n’ibikoresho bya elegitoroniki by’ubuvuzi, mu zindi nzego. Uku kwaguka kwimikorere ya porogaramu gushimangira uruhare runini rwogutambuka kutagira ingano mugutanga icyerekezo-cyiza cyo kugendana hamwe nubushobozi bwo guhagarara kubantu benshi basaba.

Ibyingenzi bigize Ubuyobozi butagira ingano:Fibre Optic Gyroscope

Intangiriro kuri Fibre Optic Gyroscopes

Sisitemu yo kugendagenda idafite imbaraga ishingiye cyane kubwukuri nibisobanuro byingenzi bigize ibice byabo. Kimwe muri ibyo bintu byazamuye cyane ubushobozi bwa sisitemu ni Fibre Optic Gyroscope (FOG). FOG ni sensor ikomeye ifite uruhare runini mugupima umuvuduko wikinyabiziga utwara neza kandi neza.

Gukora Fibre Optic Gyroscope

FOG ikora ku ihame ryingaruka za Sagnac, ikubiyemo kugabanya urumuri rwa lazeri mu nzira ebyiri zitandukanye, bikemerera kugenda mu cyerekezo gitandukanye na fibre optique. Iyo umwikorezi, yashyizwemo na FOG, azunguruka, itandukaniro ryigihe cyurugendo hagati yibiti byombi bigereranwa numuvuduko wimpande zuzunguruka. Iki gihe cyo gutinda, kizwi kwizina rya Sagnac icyiciro, noneho gipimwa neza, bigatuma FOG itanga amakuru yukuri yerekeranye no kuzenguruka kwabatwara.

Ihame rya fibre optique giroscope ikubiyemo gusohora urumuri rwumucyo uva kuri fotodektor. Urumuri rumuri runyura muri coupler, rwinjira kuva kuruhande rumwe rusohoka kurundi. Hanyuma iranyura muri optique. Imirasire ibiri yumucyo, ituruka mubyerekezo bitandukanye, winjire mumuzinga hanyuma wuzuze superpression ihuriweho nyuma yo kuzenguruka. Umucyo ugaruka wongeye kwinjira muri diode itanga urumuri (LED), ikoreshwa mukumenya ubukana bwayo. Mugihe ihame rya fibre optique giroscope rishobora gusa nkaho ryoroshye, ikibazo gikomeye cyane ni ugukuraho ibintu bigira ingaruka kumihanda ya optique yuburebure bwibiti byombi. Iki nikimwe mubibazo bikomeye byahuye nabyo mugutezimbere fibre optique giroscopes.

Ibyiza bya Fibre Optic Gyroscopes

FOGs itanga inyungu nyinshi zituma ziba ingirakamaro muri sisitemu yo kugendagenda neza. Barazwi cyane kubwukuri budasanzwe, kwiringirwa, no kuramba. Bitandukanye na giros ya mashini, FOG ntigira ibice byimuka, bigabanya ibyago byo kwambara no kurira. Ikigeretse kuri ibyo, barwanya ihungabana no kunyeganyega, bigatuma biba byiza kubidukikije bisabwa nk'ikirere hamwe na porogaramu zo kwirwanaho.

Kwishyira hamwe kwa Fibre Optic Gyroscopes muri Inertial Navigation

Sisitemu yo kugendana inertial igenda yinjizamo FOG bitewe nuburyo bwuzuye kandi bwizewe. Iyi giroskopi itanga ibipimo byingenzi byerekana umuvuduko ukenewe kugirango hamenyekane neza icyerekezo n'umwanya. Muguhuza FOG muri sisitemu yo kugendana inertial ihari, abashoramari barashobora kungukirwa no kunoza neza kugendagenda neza, cyane cyane mubihe bikenewe cyane.

Porogaramu ya Fibre Optic Gyroscopes muri Inertial Navigation

Kwinjizamo FOG byaguye porogaramu za sisitemu yo kugendana inertial muri domaine zitandukanye. Mu kirere no mu ndege, sisitemu ifite ibikoresho bya FOG itanga ibisubizo nyabyo byo kuguruka ku ndege, drone, hamwe n’icyogajuru. Zikoreshwa kandi cyane mukugenda mu nyanja, ubushakashatsi bwa geologiya, hamwe na robo yateye imbere, bituma sisitemu ikora hamwe nibikorwa byizewe kandi byizewe.

Imiterere itandukanye yuburyo bwa Fibre Optic Gyroscopes

Fibre optique giroscopes ije muburyo butandukanye bwubatswe, hamwe niganje muri iki gihe yinjira mubice byubwubatsi ni thegufunga-kuzenguruka polarisiyasi-kubungabunga fibre optique giroscope. Intandaro yiyi giroscope nipolarisiyasi-ikomeza fibre loop, igizwe na polarisiyasi-ibungabunga fibre hamwe nuburyo bwateguwe neza. Iyubakwa ryuyu muzingo ririmo uburyo bune bwo guhuza uburyo bwo guhinduranya, bwunganirwa na gel idasanzwe yo gufunga kugirango ikore fibre ikomeye ya fibre.
