Bhalisela imidiya yethu yezenhlalo yokuthumela okusheshayo
E-Epoch of GroundBreaking Technological Strikes, ama-navigation amasistimu aqhamuka njengezinsika zesisekelo, eshayela intuthuko eminingi, ikakhulukazi emikhakheni ebucayi - ebucayi. Uhambo kusuka ekuzulazuleni kwe-readimentary Celesticary kuya ku-Interitated Navigation Systems (ins) epitomizes arteity arriity attiavas yokuhlola kanye nekubumba ukunemba. Lokhu kuhlaziya kujula ku-Mechanics okuyinkimbinkimbi-ke, kuhlola ubuchwepheshe obunqenqemeni be-fiber optic gyroscopes (inkungu) kanye nendima ebaluleke kakhulu yokubandakanyeka ekugcinweni kwe-fiber loops.
Ingxenye 1: Ukuqamba amasistimu wokuhambisa navigation (ins):
Izinhlelo zokuhamba nge-inertial navigation (ins) zivelele njengezinsiza zokuzulazula ezizimele, zibonisa kahle isikhundla semoto, ukuqondisisa, kanye ne-velocity, ezimele ngezindlela zangaphandle. Lezi zinhlelo zivumelanisa ukunyakaza kanye nezinzwa ezijikelezayo, zihlanganisa ngaphandle komthungo ngamamodeli we-computational for velocity yokuqala, isikhundla kanye nokuqondiswa.
I-Archetypal ins ifaka phakathi izingxenye ezintathu zekhadinali:
· I-accelerometer: Lezi zinto ezibalulekile zibhalisa ukushesha kwemoto, ukuhumusha ukunyakaza kube yidatha enokulinganiswa.
· Gyroscopes: I-Integraal yokunquma i-angular velocity, lezi zingxenye ziyizinto ezibalulekile zokuqondiswa kohlelo.
· Module yekhompyutha
Ukungavikeleki kwezi-ins kokuphazamiseka kwangaphandle kwenza ukuthi kubaluleke kakhulu emikhakheni yezokuvikela. Kodwa-ke, inezimpoqo nge-'Drift '- ukubola okuthe xaxa kancane kancane, kudinga izixazululo eziyinkimbinkimbi njenge-sensor fusion yephutha lokunciphisa iphutha (i-Chatfield, 1997).
Ingxenye 2. Amandla okusebenza kwe-gyroscope ye-fiber optic:
I-Fibre Optic Gyroscopes (FOGS) iqondisa inkathi yokuguqula isimo ngokuzwakala okujikelezayo, ukuphazamiseka kwesibani. Ngokunemba emgogodleni wayo, inkungu ibalulekile ezimotweni ze-aerospace motor 'ukuqina nokuzula.
Inkungu isebenza emphumeleni we-sagnac, lapho kukhanya, kuthatha khona izikhombisi-ndlela zokulwa ngaphakathi kwekhoyili ye-fiber ejikelezayo, kubonisa isigaba sokushintsha kwesigaba sokuhlobana ngezilinganiso ezishintshashintshayo. Le ndlela ethokozisayo ihumusha ngamamethrikhi aqondile angular velocity.
Izakhi ezibalulekile zihlanganisa:
Umthombo wokukhanya: indawo yokuqalwa, imvamisa i-laser, eqala uhambo olubumbene.
· Ikhoyili yefayibha: I-coiled aptical mucheit, i-trajectory ekhanyayo, ngaleyo ndlela khulisa umphumela we-sagnac.
· PhotoDector: Lesi sakhi sibonisa amaphethini wokuphazamiseka ayinkimbinkimbi.
Ingxenye 3: Ukubaluleka kokulondolozwa kokugcina ama-fiber:
Ukulondolozwa kwe-polarization (PM) I-fiber loops, i-quintessential foss, qinisekisa isimo sokukhanya okufanayo, okubalulekile ngokunemba kwephethini yokuphazamisa. Le micu ekhethekile, ukulwa nemodi yokuhlakazwa kwemodi ye-polarization, ukuzwela kwenkungu ye-bolster kanye nobuqiniso bedatha (KERSEY, 1996).
Ukukhethwa kwemicu ye-PM, okuchazwe yiminyaka yokusebenza, izimfanelo ezibonakalayo, kanye nokuvumelana okuhlelekile, okuthonya ama-metric asebenza ngokweqile.
Ingxenye 4: Izicelo kanye nobufakazi obunamandla:
I-FOG NO-INS Thola ukuphikisana nakuzo zonke izicelo ezahlukahlukene, kusuka ekuhlobiseni amafayiya angenamikhawulo okuqinisekisa ukuqina kwe-cinematic phakathi kokungaphenduki kwezemvelo okungacabangi. UTestamente wabo ukuthembeka kwabo ukuthunyelwa kwabo eMars Rovers ye-NASA, kusiza ukuzulazula okuphephile kwe-Fail-ephephile (iMaimone, uCheng kanye naseMatthies, 2007).
Ama-trajectories wemakethe abikezela i-niche evuthayo yalobu buchwepheshe, ngemiphumela yokucwaninga okuhloswe ngayo ukuqinisa ukuqina kohlelo, ukucacisa umatikuletsheni, kanye nama-spectra aguqukayo (amamakethe aguqukayo, 2020).

Nesitatimende:
- Ngale ndlela simemezela ukuthi izithombe ezithile eziboniswe kuwebhusayithi yethu ziqoqwe kwi-Intanethi naseWikipedia ngezinhloso zokuqhubekisela phambili ulwazi lwemfundo nokwabelana ngalo. Sihlonipha amalungelo obunikazi bempahla yabo bonke abadali bokuqala. Lezi zithombe zisetshenziswa ngaphandle kwenhloso yenzuzo yezentengiso.
- Uma ukholelwa ukuthi noma yikuphi okuqukethwe kusetshenziswe ukwephula amalungelo okushicilela, sicela uxhumane nathi. Sizimisele kakhulu ukuthatha izinyathelo ezifanele, okubandakanya ukususa izithombe noma ukuhlinzeka ngesimo esifanele, ukuze kuqinisekiswe ukuthobela imithetho nemigomo yempahla yobunikazi. Inhloso yethu ukulondolozela ipulatifomu ecebile kokuqukethwe, okulungile, kanye nokuhlonipha amalungelo abanye abantu abanengqondo.
- Sicela usifinyelele kithi ngale ndlela elandelayo yokuxhumana,email: sales@lumispot.cn. Siyazibophezela ekuthatheni isinyathelo ngokushesha lapho sithola noma yiliphi isaziso futhi siqinisekise ukubambisana okungu-100% ekuxazululeni noma yiziphi izindaba ezinjalo.
