I-Fiber Optic Integrated Navigation System
Izici Zomkhiqizo
I-fiber optic integrated navigation system i-S300D isekelwe ku-cloc-loop fiber optic gyroscope engabizi kakhulu, i-accelerometer kanye nebhodi yokwamukela ye-GNSS ephezulu, ngokusebenzisa i-multi-sensor fusion kanye nokuqaliswa kwe-algorithm yesisombululo sokuzulazula ukuze kuhlangatshezwane nezidingo zeselula ephakathi nendawo nenembayo ephezulu. amasistimu okulinganisa, ama-UAV amakhulu, njll.
Inkambu yesicelo idinga ukulinganiswa okunembile kwesimo sengqondo, isihloko kanye nolwazi lwendawo.
Izimo zohlelo lokusebenza
Isistimu inemodi yokuzulazula ehlanganisiwe ye-inertial/satellite kanye nemodi ehlanzekile ye-inertial.
Amasathelayithi angatholwa yisamukeli se-GNSS kumodi yokuzulazula edidiyelwe ye-inertial/satellite yolwazi lokuma kwesathelayithi lokuzulazula okuhlangene;okukhiphayo esikhundleni sesixazululo se-inertial ngemva kokulahlekelwa isimo sengqondo sesivinini sesignali, ngokunemba kokuma kwezinga lemitha ngesikhathi esifushane.
Ngemuva kokuthi imodi ye-inertia emsulwa isiqalile, inomsebenzi wokulinganisa isimo sengqondo esinembile futhi ingakhipha ukugeleza kwephimbo nesihloko, inertia emsulwa ingafuna enyakatho ngokwezibalo.
Izici Zomkhiqizo
- Ukunemba kwesikhundla kuze kufike ezingeni lamasentimitha
- Iphutha lokulinganisa isimo sengqondo lingcono kuno-0.01°
- Ibanga lokushisa elisebenzayo: -40 ~ 60 ℃
- Imvelo yokudlidliza: 20 ~ 2000Hz, 3.03g
- Izinhlobo ze-interface ezicebile, isekela i-RS232, i-RS422, i-CAN nezinye izixhumi ezibonakalayo ezijwayelekile
- Isikhathi esimaphakathi phakathi kokwehluleka kufika ku-30000h
Izici zikagesi
- Ukunikezwa kwamandla: okokufaka kwe-voltage ebanzi 12 ~ 36V
- Amandla alinganiselwe: 24W (ubukhulu)
