IMU sensor: mawonekedwe ndi kusanthula

M'malo aukadaulo omwe akusintha mwachangu, masensa a inertial measurement unit (IMU) akhala zinthu zofunika kwambiri pakugwiritsa ntchito kuyambira pamagetsi ogula mpaka ma robotiki apamwamba. Sensa ya IMU ndi chipangizo chosavuta chomwe chimapangidwa kuti chizitha kuyeza mawonekedwe a axis atatu a chinthu komanso kuchuluka kwake komanso kuthamanga kwake. Katunduyu amapangitsa kuti ikhale yofunikira kwambiri pakuthana ndi zovuta zovuta zokhudzana ndi kuyenda, kuyang'ana ndi kuwongolera kuyenda.

Kapangidwe ndi mfundo ntchito

TheSensor ya IMUmakamaka imakhala ndi zigawo ziwiri zofunika: accelerometer ndi gyroscope. Ma Accelerometer amayesa kuthamanga kwa mzere wa chinthu motsatira nkhwangwa zitatu (X, Y, ndi Z). Komano, ma gyroscopes, amayesa kuthamanga kwa ngodya, kupereka chidziwitso chofunikira chokhudza kusuntha kwa chinthu.

Masensa awa amatha kugwiritsidwa ntchito payekhapayekha kapena kuphatikiza kuti apange dongosolo la IMU la 6 kapena 9-axis. Machitidwe a 6-axis nthawi zambiri amaphatikizapo ma accelerometers atatu ndi ma gyroscopes atatu, pamene makina asanu ndi anayi amawonjezera ma magnetometer kuti apereke zambiri zowonjezera. Poyesa mosalekeza kusintha kwa inertia, masensa a IMU amatha kulingalira momwe chinthu chimayendera, kuphatikizapo malo ake, liwiro ndi maganizo. Deta yanthawi yeniyeniyi ndiyofunikira pamapulogalamu omwe amafunikira kutsata kolondola komanso kuwongolera.

Zochitika zantchito

Masensa a IMUndi zosunthika ndipo zitha kugwiritsidwa ntchito m'mafakitale osiyanasiyana. M'gawo lamagalimoto, amagwira ntchito yofunika kwambiri kuti magalimoto azikhala okhazikika komanso kuyenda. Popereka deta yeniyeni yokhudzana ndi kayendetsedwe ka galimoto ndi kuthamanga kwake, masensa a IMU amathandiza makina othandizira oyendetsa galimoto (ADAS) kuti azigwira ntchito bwino, kupititsa patsogolo chitetezo ndi ntchito.

Mu ma robotiki, masensa a IMU ndi ofunikira kuti azikhala okhazikika komanso okhazikika. Amathandizira maloboti kulosera liwiro lawo komanso momwe amayendera, motero amawongolera malo olondola komanso kuyenda. Kuthekera kumeneku ndikofunikira kwambiri pamapulogalamu monga magalimoto odziyendetsa okha ndi ma drones, komwe kuyenda kolondola ndikofunikira kuti ntchitoyo ikhale yabwino.

Kuphatikiza apo, masensa a IMU akuphatikizidwa kwambiri mumagetsi ogula, monga mafoni am'manja ndi zida zamasewera. Amakulitsa luso la wogwiritsa ntchito pothandizira zinthu monga zowongolera zoyenda komanso kugwiritsa ntchito zenizeni zenizeni. M'makina owongolera mafakitale, masensa a IMU amathandizira kukwaniritsa zodziwikiratu komanso kuchita bwino, kulola kuyang'anira bwino ndikuwongolera makina.

Makampani opanga ndege apindulanso kwambiri ndi luso la IMU. M'ndege ndi ndege, masensa a IMU amagwiritsidwa ntchito poyendetsa ndi kuwongolera maganizo kuti awonetsetse kuti ndegezi zitha kugwira ntchito motetezeka komanso moyenera m'malo ovuta.

Powombetsa mkota

Mwachidule,Masensa a IMUndi matekinoloje ofunikira omwe amathandizira ntchito zambiri m'magawo osiyanasiyana. Kukhoza kwake kuyeza kuthamanga ndi kuthamanga kwa angular ndi kulondola kwakukulu kumapangitsa kukhala chida chofunika kwambiri pakuyenda, kuyang'ana ndi kuyendetsa. Pamene teknoloji ikupitirirabe patsogolo, udindo wa masensa a IMU udzakhala wotchuka kwambiri, kuyendetsa luso komanso kupititsa patsogolo magwiridwe antchito a zipangizo zamakono. Kaya mumakina amagalimoto, ma robotiki, zamagetsi ogula kapena zakuthambo, masensa a IMU nthawi zonse azikhala patsogolo pazachitukuko chaukadaulo kuti apange dziko lanzeru, lolumikizana kwambiri.
