ʻAno 100 Rotary Fiber Strapdown Inertial Navigation System
wehewehe huahana
Ke hoʻolauna nei i ka FS100, kahi ʻōnaehana holoʻokoʻa i hoʻolālā ʻia e hāʻawi i ke ana pololei kiʻekiʻe a me nā mana mana.Aia kēia ʻōnaehana holomua i kekahi mau mea nui, me ka Inertial Measurement Unit (IMU), Rotation Mechanism, Navigation Computer, GNSS Board, Navigation Software, DC Power Supply, a me Mechanical Components.
ʻO ka IMU, he mea koʻikoʻi o ka FS100, he ʻekolu gyroscopes fiber optic kiʻekiʻe, ʻekolu quartz flexure accelerometers, kamepiula hoʻokele, kahi lako mana lua, a me kahi kaapuni ʻikepili.Me ka hoʻohana ʻana i kahi gyroscope fiber optic gyroscope, accelerometer, a me ka papa hoʻokipa GNSS kiʻekiʻe, hoʻohana ka ʻōnaehana FS100 i ka ʻokiʻoki multi-sensor fusion a me nā algorithm hoʻokele e hāʻawi i ka pololei ʻokoʻa i ka ʻano, ka wikiwiki, a me ka ʻike kūlana.
Hāʻawi ka ʻōnaehana FS100 i nā ana kikoʻī kiʻekiʻe a me nā koi hoʻomalu ma waena o nā noi he nui.ʻO kāna mau wahi noi nui e komo pū me:
Nui UAV Reference Inertial Guidance: Hāʻawi ka FS100 i nā mana alakaʻi inertial pololei no nā kaʻa lewa nui ʻole (UAV), e hōʻoia i ka hoʻokele maikaʻi loa a me ka mana.
Kāpena Moana: Me kona pololei kiʻekiʻe a me ka paʻa, lawelawe ka FS100 ma ke ʻano he hopena panana kūpono no nā noi kai.
ʻO ka hoʻonohonoho ʻana i nā artillery pono'ī: Hāʻawi ka ʻōnaehana FS100 i nā hiki ke hoʻonohonoho pono no nā ʻōnaehana pū hoʻokele ponoʻī, hiki ke hoʻopaʻa pololei ʻia a me ka mana.
Hoʻonohonoho a me ka hoʻonohonoho ʻana i nā kaʻa: Ke hoʻohana nei i ka FS100, hiki i nā kaʻa ke hoʻokō pololei i ke kūlana a me ka hoʻonohonoho ʻana, hoʻonui i ka hoʻokele a me ka hoʻokele ʻana i nā kaiapuni like ʻole.
Ana Kiʻekiʻe-Precision Mobile: ʻOi aku ka FS100 i nā hiʻohiʻona ana kelepona paʻa kiʻekiʻe, e hāʻawi ana i nā ʻikepili ana pololei a hilinaʻi no kahi ākea o nā noi.
Kiʻekiʻe-Precision Stable Platform: Me kona kūpaʻa kūʻokoʻa a me ka pololei, ʻo ka FS100 kahi kūpono kūpono no nā noi paʻa paʻa kiʻekiʻe, e hōʻoiaʻiʻo ana i ka hana pono a pololei.
E ʻike i ke kiʻekiʻe o ke ana a me ka hoʻomalu ʻana me ka FS100, kahi hoʻonā piha i hoʻolālā ʻia e hoʻokō i nā koi koi loa i nā ʻoihana like ʻole.
HANA NUI
Ua hui pū ka ʻōnaehana i ke ʻano hoʻokele inertial/satellite a me ke ʻano inertial maʻemaʻe.
ʻO ke alakaʻi inertial i kūkulu ʻia i ka papa GNSS, ke hiki ke hoʻohui ʻia ke alakaʻi inertial GNSS me GNSS no ka hoʻokele, a hāʻawi i ke kūlana hui, kiʻekiʻe, wikiwiki, ʻano, poʻomanaʻo, acceleration, angular velocity a me nā ʻāpana hoʻokele ʻē aʻe i ka mea hoʻohana, ʻoiai e hoʻopuka ana. Ke kūlana GNSS, ke kiʻekiʻe, ka wikiwiki a me nā ʻike ʻē aʻe.
Ke hewa ʻole ʻo GNSS, hiki iā ia ke komo i ke ʻano inertial maʻemaʻe (ʻo ia hoʻi, ʻaʻole ia i hana i ka GPS fusion ma hope o ka mana, a inā nalowale ka laka ma hope o ka hui ʻana, pili ia i ke ʻano hoʻokele hui) Ma hope o ka hoʻomaka ʻana, loaʻa iā ia ke ana ʻano pololei. hana, hiki ke hoʻopuka i ka pitch a me ka ʻōwili poʻomanaʻo, a ʻo ka inertial maʻemaʻe hiki ke ʻike i ka ʻākau.
Aia nā hana nui
l ka hana alignment mua: ka mana alakaʻi inertial a kali i ka ʻike satellite, kūpono ka satellite no 300s alignment, hoʻopau ʻia ka alignment ma hope o ka hoʻololi ʻana i ke alakaʻi inertial mokuʻāina hoʻokele hui;
l ka hana hoʻokele hui: ma hope koke o ka hoʻonohonoho mua ʻana i ka mokuʻāina hoʻokele hui, alakaʻi inertial me ka hoʻohana ʻana i ka papa GNSS kūloko no ka hoʻokele hui ʻana, hiki ke hoʻonā i ka wikiwiki o ka mea lawe, ke kūlana a me ke ʻano a me nā ʻike hoʻokele ʻē aʻe;
l ka hana kamaʻilio: hiki i ke alakaʻi inertial ke hoʻopuka i ka ʻike ana alakaʻi inertial i waho e like me ka protocol;
l me ka hiki ke hoʻonui i ka lako polokalamu ma kahi o ka moku: hiki ke hoʻonui ʻia ka polokalamu hoʻokele ma o ke awa serial;
l me nā hiki ke ʻike ponoʻī, i ka wā i hāʻule ʻole ai ka ʻōnaehana, hiki ke hoʻouna i ka ʻike hewa ʻole, ʻōlelo aʻo i nā mea pono;
l me ka wobble alignment hana.
Hōʻike ʻia ke kaʻina hana alakaʻi inertial ma ka Figure 1 ma lalo nei.
