Nidaamyada Navigation Inertial iyo Tignoolajiyada Fiber Optic Gyroscope

Ku Soo Biir Baraha Bulshada Si Aad U Hesho Qoraal Deg Deg Ah

Xilligii horumarka tignoolajiyada, nidaamyada hagiddu waxay u soo baxeen sidii tiirar aasaasi ah, oo horseedaya horumarro badan, gaar ahaan waaxyada saxda ah ee muhiimka ah. Safarka laga soo bilaabo navigation jannada rudimentary ilaa Nidaamyada Navigation Inertial Inertial Navigation (INS) ee casriga ah ayaa muujinaya dadaallada aan loo meel dayin ee bini'aadamka ee sahminta iyo tilmaamaya saxnaanta. Falanqayntan ayaa si qoto dheer u dhex galaysa makaanikada qalafsan ee INS, iyada oo sahaminta tignoolajiyada cirifka ah ee Fiber Optic Gyroscopes (FOGs) iyo doorka muhiimka ah ee Polarization ee Ilaalinta Wareegyada Fiberka.

Qeybta 1: Go'aaminta Nidaamyada Hagidda Inertial (INS):

Nidaamyada Navigation-ka Inertial (INS) waxay u taagan yihiin inay yihiin gargaaraha duulista, iyagoo si sax ah u xisaabinaya booska gaariga, jihaynta, iyo xawaaraha, ka madax bannaan tilmaamo dibadda ah. Nidaamyadani waxay iswaafajiyaan dhaqdhaqaaqa iyo dareemayaasha wareega, iyagoo si aan kala go 'lahayn ugu dhex milmay moodooyinka xisaabinta ee xawaaraha bilowga, booska, iyo jihaynta.

INS-da qadiimiga ah waxay ka kooban tahay saddex qaybood oo wadnaha ah:

Xawaareyaal: Cutubyadan muhiimka ah waxay diiwaangeliyaan dardargelinta toosan ee baabuurka, iyagoo dhaqdhaqaaqa u turjumaya xog la cabbiri karo.
· Gyroscopes: Isku-dhafan si loo go'aamiyo xawaaraha xaglaha, qaybahan ayaa udub-dhexaad u ah jihaynta nidaamka.
Module Kombuyuutar: Xarunta neerfaha ee INS, oo farsamaysa xog dhinacyo badan leh si ay u soo saarto falanqaynta booska wakhtiga dhabta ah.

Xasaanadda INS ee carqaladaynta dibadda ayaa ka dhigaysa mid aan looga maarmin qaybaha difaaca. Si kastaba ha ahaatee, waxa ay la daalaa dhacaysa 'fiditaanka' - suubban si tartiib ah, oo u baahan xalal casri ah sida fiyuuska dareenka yaraynta khaladka (Chatfield, 1997).

Nidaamka Qaybaha Navigation Inertial Isdhexgalka

Qaybta 2. Dhaqdhaqaaqa Dhaqdhaqaaqa Fiber Optic Gyroscope:

Fiber Optic Gyroscopes (FOGs) waxa ay ku bishaareeyaan xilli isbedel ah xagga dareenka wareega, ka faa'iidaysiga faragelinta iftiinka. Iyada oo saxda ah xudunta u ah, FOGs ayaa muhiim u ah xasilinta iyo socodka gaadiidka hawada sare.

FOG-yadu waxay ku shaqeeyaan saamaynta Sagnac, halkaas oo iftiinku, oo u gudba jihooyinka counter-ka ee ku dhex jira gariiradda fibre-gaaban ee wareegta ah, uu muujiyo isbeddel weji oo la xidhiidha isbeddelada heerka wareegta. Habkan nuanceed waxa uu u tarjumaa qiyaasaha xawliga xaglaha ee saxda ah.

Qaybaha muhiimka ah waxay ka kooban yihiin:

Isha Iftiinka: Barta ka-hortagga, sida caadiga ah laysarka, oo bilaabaysa safarka iftiinka ee isku xidhan.
· Gariiradda Fiber: Dhuunta indhaha oo duuban, waxay dheeraysaa jihada iftiinka, taas oo kor u qaadaysa saamaynta Sagnac.
Sawir-qaade: Qaybtani waxay kala garanaysaa qaababka faragelinta adag ee iftiinka.

Qaybta 3: Muhiimadda Kala-soocidda Ilaalinta Wareegyada Fiber-ka:

 

Ilaalinta Dabaysha (PM) Fiber Loops, oo muhiim u ah FOG-yada, waxay xaqiijisaa xaalada kala soocida isku midka ah ee iftiinka, go'aamiye fure u ah saxnaanta qaabka faragelinta. Fiilooyinkan khaaska ah, la dagaalanka kala firdhisanaanta qaabka polarization, xoojiya dareenka FOG iyo xaqiiqada xogta (Kersey, 1996).

Xulashada fiilooyinka PM-ka, ee lagu tilmaamo ka-baxyada hawl-galka, sifooyinka jireed, iyo is-waafajinta nidaamka, waxay saameeyaan cabbirrada waxqabadka guud.

Qeybta 4: Codsiyada iyo Caddeynta Dhabta ah:

FOG-yada iyo INS waxay ka helayaan dhawaaqyo codsiyo kala duwan ah, laga soo bilaabo abaabulka duullimaadyada hawada aan duuliyaha lahayn ilaa hubinta xasilloonida shaleemada iyada oo ay jirto lama saadaalin karo deegaanka. Marqaati u ah isku halayntooda ayaa ah geyntooda NASA ee Mars Rovers, fududaynta badqabka badqabka ah ee hagidda dhulka (Maimone, Cheng, iyo Matthies, 2007).

Mawduucyada suuqyadu waxay saadaaliyaan niche soo koraya ee tignoolajiyadan, oo leh cilmi-baaris cilmi-baariseed oo loogu talagalay xoojinta adkaysiga nidaamka, jaantusyada saxda ah, iyo muuqaalka la-qabsiga (Suuqyada iyoMarkets, 2020).
