Ingolise ho Mecha ea Rona ea Litaba tsa Sechaba bakeng sa Poso e Potlakileng
Nakong ea tsoelo-pele e ncha ea theknoloji, litsamaiso tsa ho tsamaea li ile tsa hlaha e le litšiea tsa motheo, tsa khanna tsoelo-pele e mengata, haholo-holo mafapheng a bohlokoa ka ho nepahala. Leeto ho tloha ho tsamaisong ea maholimo ea motheo ho ea ho Mekhoa e rarahaneng ea ho Tsamaea ea Inertial (INS) le bontša boiteko bo sa fetoheng ba batho ba ho batla le ho nepahala ho totobetseng. Tlhahlobo ena e teba ka botebo mek'henikeng e rarahaneng ea INS, e hlahloba theknoloji ea sejoale-joale ea Fiber Optic Gyroscopes (FOGs) le karolo ea bohlokoa ea Polarization ho Boloka Li-Fiber Loops.
Karolo ea 1: Ho Hlalosa Mekhoa ea ho Tsamaea e sa Laoleheng (INS):
Mekhoa ea ho Tsamaea ea Inertial (INS) e hlahella e le lithuso tsa ho tsamaea tse ikemetseng, e bala boemo ba koloi, tataiso le lebelo ka nepo, ntle le matšoao a kantle. Mekhoa ena e hokahanya li-sensor tsa motsamao le potoloho, e kopana ka mokhoa o se nang sekoli le mehlala ea lik'homphieutha bakeng sa lebelo la pele, boemo le tataiso.
INS ea archetypal e kenyelletsa likarolo tse tharo tsa bohlokoa:
· Li-accelerometer: Lintho tsena tsa bohlokoa li ngolisa lebelo le otlolohileng la koloi, li fetolela motsamao hore e be data e ka lekanngoang.
· Li-Gyroscope: Li bohlokoa bakeng sa ho fumana lebelo la angular, likarolo tsena ke tsa bohlokoa bakeng sa tataiso ea sistimi.
· Mojule oa Khomphutha: Setsi sa methapo ea kutlo sa INS, se sebetsanang le lintlha tse nang le mahlakore a mangata ho hlahisa tlhahlobo ea boemo ba nako ea sebele.
Ho itšireletsa ha INS litšitisong tsa kantle ho etsa hore e be ea bohlokoa haholo makaleng a tšireletso. Leha ho le joalo, e sebetsana le 'ho kheloha' - ho bola butle-butle ha ho nepahala, ho hlokang litharollo tse rarahaneng joalo ka ho kopanya sensor bakeng sa ho fokotsa liphoso (Chatfield, 1997).
Karolo ea 2. Matla a Ts'ebetso ea Gyroscope ea Fiber Optic:
Li-Gyroscope tsa Fiber Optic (FOGs) li phatlalatsa mehla ea phetoho ho utloang ho potoloha, li sebelisa tšitiso ea leseli. Ka ho nepahala ha eona, li-FOG li bohlokoa bakeng sa ho tsitsisa le ho tsamaea ha likoloi tsa sefofane.
Li-FOG li sebetsa holim'a phello ea Sagnac, moo leseli, le fetang ka litsela tse fapaneng ka har'a coil ea faeba e potolohang, le bonts'a phetoho ea mohato e amanang le liphetoho tsa sekhahla sa ho potoloha. Mokhoa ona o nang le lintlha tse fapaneng o fetolela ho litekanyo tse nepahetseng tsa lebelo la angular.
Likarolo tsa bohlokoa li kenyelletsa:
· Mohloli oa Leseli: Sebaka sa ho qala, hangata ke laser, se qalang leeto la leseli le kopaneng.
· Koili ea Faeba: Mokero o kobehileng wa optical, o lelefatsa tsela ya lesedi, ka hona o eketsa phello ya Sagnac.
· Sesebediswa sa ho lemoha foto: Karolo ena e lemoha dipaterone tse rarahaneng tsa tshitiso ya lesedi.
Karolo ea 3: Bohlokoa ba ho Boloka Li-Fiber Loops tsa Polarization:
Li-Fiber Loops tsa ho Boloka Polarization (PM), tse hlokahalang bakeng sa FOGs, li netefatsa boemo bo tšoanang ba polarization ba leseli, e leng ntho ea bohlokoa e khethollang ho nepahala ha paterone ea tšitiso. Li-fiber tsena tse ikhethileng, li loantša ho hasana ha mokhoa oa polarization, li matlafatsa kutloisiso ea FOG le bonnete ba data (Kersey, 1996).
Khetho ea likhoele tsa PM, e laoloang ke litlhoko tsa ts'ebetso, litšobotsi tsa 'mele le kutloano ea tsamaiso, e susumetsa litekanyo tse akaretsang tsa ts'ebetso.
Karolo ea 4: Litšebeliso le Bopaki bo Bontšang Katleho:
FOG le INS li fumana kutloano lits'ebetsong tse fapaneng, ho tloha ho hlophiseng maeto a sefofane a sa laoleheng ho isa ho netefatseng botsitso ba cinema har'a ho se tsejoe esale pele ha tikoloho. Bopaki ba ho tšepahala ha tsona ke ho kenngoa ha tsona ho Mars Rovers ea NASA, ho nolofalletsa ho tsamaea ka sefofane kantle ho lefatše ka mokhoa o sireletsehileng (Maimone, Cheng, le Matthies, 2007).
Mekhoa ea 'maraka e bolela esale pele sebaka se ntseng se hola bakeng sa mahlale ana, ka li-vector tsa lipatlisiso tse reretsoeng ho matlafatsa ho tiea ha sistimi, matrices e nepahetseng, le li-spectra tsa ho ikamahanya le maemo (MarketsandMarkets, 2020).
