Ụdị 100 Rotary Fiber Strapdown Inertial Navigation System
Nkọwa ngwaahịa
Na-ewebata FS100, usoro zuru oke e mere iji nye nha nha na ikike njikwa dị elu.Sistemu dị elu nwere ọtụtụ ihe isi ihe, gụnyere Ngalaba Inertial Measurement Unit (IMU), Rotation Mechanism, Kọmputa ngagharị, bọọdụ GNSS, Software Navigation, Nnyefe ọkụ DC, na Ngwa Mechanical.
IMU, akụkụ dị mkpa nke FS100, nwere eriri gyroscopes fiber optic atọ dị elu, quartz flexure accelerometers atọ, kọmpụta igodo, ọkọnọ ike nke abụọ, yana sekit nnweta data.N'iji eriri gyroscope emechiri emechi emechiri emechi, ihe osooso na bọọdụ nnabata GNSS dị elu, sistemụ FS100 na-eji ngwakọta ọtụtụ ihe mmetụta dị mma na algọridim igodo iji wepụta izi ezi pụrụiche na omume, ọsọ na ozi ọnọdụ.
Usoro FS100 na-eme ka nha dị elu dị elu yana ihe njikwa chọrọ n'ofe ọtụtụ ngwa.Ebe isi ngwa ya gụnyere:
Nnukwu ntụzi aka inertial UAV: FS100 na-enye ikike nduzi inertial ziri ezi maka ụgbọ ala ikuku na-enweghị mmadụ (UAV), na-eme ka igodo na njikwa kacha mma.
Kompas mmiri: Site na nkwụsi ike ya dị elu na nkwụsi ike, FS100 na-eje ozi dị ka ezigbo ngwọta kompas maka ngwa mmiri.
Ntuzi aka ogbunigwe nke onwe: Usoro FS100 na-enye ikike ntụzịaka ziri ezi maka sistemu ogbunigwe na-ebugharị onwe ya, na-eme ka ebumnuche na njikwa ziri ezi.
Ọnọdụ dabere na ụgbọ ala na nghazi: N'iji FS100, ụgbọ ala nwere ike nweta nhazi na nhazi nke ọma, na-eme ka igodo na njikwa na gburugburu ebe dị iche iche.
Ntụkọ ekwentị dị elu nke ọma: FS100 karịrị n'ọnọdụ nha ekwentị dị elu, na-ebuga data nha ziri ezi na ntụkwasị obi maka ọtụtụ ngwa.
Platform dị elu dị elu: Site na nkwụsi ike ya na nkenke, FS100 bụ ihe dabara nke ọma maka ngwa ikpo okwu kwụsiri ike dị elu, na-eme ka a rụọ ọrụ nke ọma na ntụkwasị obi.
Nweta oke nha na njikwa dị elu na FS100, ihe ngwọta zuru oke emebere iji zute ihe ndị kachasị achọ na ụlọ ọrụ dị iche iche.
Isi ọrụ
Sistemu ejikọtara ọnọdụ inertial/satellite navigation mode yana ezigbo inertial mode.
Inertial ndu wuru na GNSS bọọdụ, mgbe GNSS dị irè inertial ndu nwere ike ijikọ na GNSS maka igodo, na-enye ndị jikọtara ọnọdụ, elu, ọsọ, àgwà, isiokwu, osooso, angular ọsọ na ndị ọzọ navigation parameters na onye ọrụ, mgbe mmepụta. Ọnọdụ GNSS, elu, ọsọ na ozi ndị ọzọ.
Mgbe GNSS adịghị mma, ọ nwere ike ịbanye na ọnọdụ inertial dị ọcha (ya bụ, ọ dịtụbeghị mgbe ọ rụchara GPS fusion mgbe agbanyere ọkụ, ma ọ bụrụ na ọ tufuru mkpọchi ọzọ mgbe ngwakọta ahụ gasịrị, ọ bụ nke ọnọdụ igodo jikọtara ọnụ) Mgbe ịmalitere, ọ nwere nha àgwà ziri ezi. ọrụ, nwere ike wepụta pitch na mpịakọta isiokwu, na dị ọcha inertial nwere ike ịbụ static n'ebe ugwu chọta.
Isi ọrụ gụnyere
l ọrụ nhazi nke mbụ: ike nduzi inertial na-echere maka ozi satịlaịtị dị irè, satịlaịtị dị irè maka nhazi 300s, nhazi na-agwụcha mgbe a na-enyefe ya na nchikota igodo steeti inertial ndu;
l arụ ọrụ igodo jikọtara ọnụ: ozugbo ntinye nke mbụ n'ime steeti igodo jikọtara ọnụ, ntuziaka inertial na-eji bọọdụ GNSS dị n'ime maka ịnya ụgbọ mmiri jikọtara ọnụ, nwere ike dozie ọsọ nke onye na-ebu ụgbọ, ọnọdụ na àgwà na ozi igodo ndị ọzọ;
l ọrụ nzikọrịta ozi: onye ndu inertial nwere ike wepụta ozi nha ntụzịaka inertial n'èzí dịka protocol siri dị;
l na ikike ịkwalite ngwanrọ na ọnọdụ n'ime ụgbọ: enwere ike ịkwalite ngwanrọ igodo site na ọdụ ụgbọ mmiri;
l nwere ikike ịchọpụta onwe onye, mgbe sistemụ ọdịda, nwee ike izipu ozi na-ezighi ezi, ịdọ aka ná ntị na akụrụngwa dị mkpa;
